FROM THE PRESIDENT AND EVP: MOVING INFORMATION IN THE DIGITAL AGE For the past four years, Dr. Laura W. Lamps has led the Education Committee to adopt a more progressive attitude regarding changes in presentation methodology, including the incorporation of interactive elements such as audience response systems, utilization of virtual slides, interactive microscopy modalities and a pilot approach to converting the traditional classroom to an interactive conversational venue. As Dr. Lamps transitions from her position as Chair of the Education Committee, she is recognized for excellence as the recipient of the 2017 President s Award. N. Volkan Adsay, M.D. President David B. Kaminsky, M.D., FIAC Executive Vice President Pathologists are confronted with information overload on a daily basis. Laboratories generate more than 70% of the medical record with increasingly greater impact on the delivery of healthcare. Pathology requires constant updates in new developments relevant to translational research, improved diagnostic criteria, novel methodologies and practice changers in order to fulfill its increasing role in disease management and prognostication. USCAP is a force in information generation and delivery in the world of diagnostics, and is moving pathology education to the next dimension. The 2017 Annual Meeting showcases how USCAP delivers crucial information, curated by experts, packaged in modular units, distributed digitally, available on demand, and accessible also on mobile devices. Social media is now an integral part of the information transfer. The USCAP Social Media Committee celebrated achieving 29 million tweet impressions during the 2016 Annual Meeting and routinely moves information on Facebook, Twitter, Instagram and YouTube. A novel approach was the broadcast from the USCAP Interactive Center of a segment of Dr. Jason Hornick s interactive microscopy course on soft tissue tumors on FaceBook Live on December 11, 2016. The educational programs of this meeting will now also become a part of the new modern library of digital educational assets that are professionally re-mastered and/ or developed at the studio of the USCAP Linder Learning Center, providing long-term (and much wider) access to highly respected information presented at USCAP meetings. While USCAP is proud of the way it delivers critical information, it s important to remember that we are also the consummate platform for cutting edge research in diagnostic pathology. This Annual Meeting attracted the submission of 2,700 abstracts encompassing all subspecialty areas of translational research in anatomic and molecular pathology. As in the past, the research presented and discussed at this meeting with the participation of thousands from our community will ultimately move from platforms and poster boards, leading the way to progress, new diagnostic criteria and creation of the basis of precision medicine. In this Meeting, and throughout the year at the USCAP Learning Center in Palm Springs, CA, you will also have the opportunity to benefit from the USCAP interactive microscopy sessions, 36 concise courses organized for you under the leadership of Dr. Steven Billings. Our and membership have determined that offering our educational programs also to pathologists practicing in under-resourced countries is an essential part of our mission. The engagement of Paul Lewin as Director of International Development has been an extraordinary impetus to innovating education, fostering the next generation of pathologists and promoting global health. He has facilitated, in collaboration with the Foundation Committee, the opportunity for 20 pathologists from underserved countries and 15 pathologists-in-training to attend this meeting; promoted growth of funds that support the USCAP Interactive Learning Center; and revolutionized the way courses and digital products from the Interactive Learning Center are managed for exposure and sales. Global health through philanthropy is a strategic initiative of the Academy, and we are proud of the progress we continue to make in its support. The recently improved USCAP website, www.uscap.org, is your resource for all things about the Academy. Its functional, aesthetic and personalized format is now customized to your needs and convenience. Be sure to use the APP for navigating this meeting. Harness your energies to explore all facets of this energizing and stimulating educational event. Don t miss the Maude Abbott Lecture and USCAP Honors special program at 4:15 P.M. on Tuesday, March 7, in the Stars at Night ballroom, or the Generation U celebration which is for and about you. And what you can say about yourself at the end of the week is: #IAMUSCAP. I AM A BETTER PATHOLOGIST.

WHEN PATIENTS PROGRESS, IT S TIME TO TEST IMPORTANT SAFETY INFORMATION There are no contraindications for TAGRISSO Interstitial Lung Disease (ILD)/Pneumonitis occurred in 3.3% and was fatal in 0.5% of 813 TAGRISSO patients. Withhold TAGRISSO and promptly investigate for ILD in any patient presenting with worsening of respiratory symptoms indicative of ILD (e.g., dyspnea, cough and fever). Permanently discontinue TAGRISSO if ILD is confirmed QTc interval prolongation occurred in TAGRISSO patients. Of the 411 patients in two Phase II studies, 0.2% were found to have a QTc greater than 500 msec, and 2.7% had an increase from baseline QTc greater than 60 msec. Conduct periodic monitoring with ECGs and electrolytes in patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval. Permanently discontinue TAGRISSO in patients who develop QTc interval prolongation with signs/symptoms of life threatening arrhythmia Cardiomyopathy occurred in 1.4% and was fatal in 0.2% of 813 TAGRISSO patients. Left Ventricular Ejection Fraction (LVEF) decline >10% and a drop to <50% occurred in 2.4% of (9/375) TAGRISSO patients. Assess LVEF before initiation and then at 3 month intervals of TAGRISSO treatment. Withhold TAGRISSO if ejection fraction decreases by 10% from pretreatment values and is less than 50%. For symptomatic congestive heart failure or persistent asymptomatic LV dysfunction that does not resolve within 4 weeks, permanently discontinue TAGRISSO Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during TAGRISSO treatment and for 6 weeks after the final dose. Advise males with female partners of reproductive potential to use effective contraception for 4 months after the final dose The most common adverse reactions (>20%) observed in TAGRISSO patients were diarrhea (42%), rash (41%), dry skin (31%) and nail toxicity (25%) INDICATION TAGRISSO is indicated for the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC), as detected by an FDA-approved test, who have progressed on or after EGFR tyrosine kinase inhibitor therapy. This indication is approved under accelerated approval based on tumor response rate and duration of response.

TAGRISSO TM (osimertinib) tablets, for oral use Brief Summary of Prescribing Information. For complete prescribing information consult official package insert. INDICATIONS AND USAGE TAGRISSO is indicated for the treatment of patients with metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC), as detected by an FDA-approved test, who have progressed on or after EGFR tyrosine kinase inhibitor (TKI) therapy. This indication is approved under accelerated approval based on tumor response rate and duration of response [see Clinical Studies (14) in full Prescribing Information]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. DOSAGE AND ADMINISTRATION Patient Selection Confirm the presence of a T790M EGFR mutation in tumor or, in the absence of tumor, plasma specimens prior to initiation of treatment with TAGRISSO [see Indications and Usage (1) and Clinical Studies (14) in full Prescribing Information]. Testing for the presence of the mutation in plasma specimens is recommended only in patients for whom a tumor biopsy cannot be obtained. If this mutation is not detected in a plasma specimen, re-evaluate the feasibility of biopsy for tumor tissue testing. Information on FDA-approved tests for the detection of T790M mutations is available at http://www.fda.gov/companiondiagnostics. Recommended Dosage Regimen The recommended dose of TAGRISSO is 80 mg tablet once a day until disease progression or unacceptable toxicity. TAGRISSO can be taken with or without food. If a dose of TAGRISSO is missed, do not make up the missed dose and take the next dose as scheduled. Administration to Patients Who Have Difficulty Swallowing Solids Disperse tablet in 60 ml (2 ounces) of non-carbonated water only. Stir until tablet is dispersed into small pieces (the tablet will not completely dissolve) and swallow immediately. Do not crush, heat, or ultrasonicate during preparation. Rinse the container with 120 ml to 240 ml (4 to 8 ounces) of water and immediately drink. If administration via naso-gastric tube is required, disperse the tablet as above in 15 ml of non-carbonated water, and then use an additional 15 ml of water to transfer any residues to the syringe. The resulting 30 ml liquid should be administered as per the nasogastric tube instructions with appropriate water flushes (approximately 30 ml). Dosage Modification Adverse Reactions Table 1 Recommended Dose Modifications for TAGRISSO Target Organ Adverse Reaction a Dose Modification Interstitial lung disease Permanently discontinue TAGRISSO. Pulmonary (ILD)/Pneumonitis a b c Cardiac Other QTc interval greater than 500 msec on at least 2 separate ECGs b QTc interval prolongation with signs/symptoms of life-threatening arrhythmia Asymptomatic, absolute decrease in LVEF c of 10% from baseline and below 50% Symptomatic congestive heart failure Grade 3 or higher adverse reaction If improvement to Grade 0-2 within 3 weeks If no improvement within 3 weeks Withhold TAGRISSO until QTc interval is less than 481 msec or recovery to baseline if baseline QTc is greater than or equal to 481 msec, then resume at 40 mg dose. Permanently discontinue TAGRISSO. Withhold TAGRISSO for up to 4 weeks. If improved to baseline LVEF, resume. If not improved to baseline, permanently discontinue. Permanently discontinue TAGRISSO. Withhold TAGRISSO for up to 3 weeks. Resume at 80 mg or 40 mg daily. Permanently discontinue TAGRISSO. Adverse reactions graded by the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 (NCI CTCAE v4.0). ECGs = Electrocardiograms LVEF = Left Ventricular Ejection Fraction QTc = QT interval corrected for heart rate Drug Interactions Strong CYP3A4 Inducers If concurrent use is unavoidable, increase TAGRISSO dosage to 160 mg daily when coadministering with a strong CYP3A inducer. Resume TAGRISSO at 80 mg 3 weeks after discontinuation of the strong CYP3A4 inducer [see Drug Interactions (7), and Clinical Pharmacology (12.3) in full Prescribing Information]. CONTRAINDICATIONS None. WARNINGS AND PRECAUTIONS Interstitial Lung Disease/Pneumonitis Across clinical trials, interstitial lung disease (ILD)/pneumonitis occurred in 3.3% (n=27) of TAGRISSO treated patients (n=813); 0.5% (n=4) were fatal. Withhold TAGRISSO and promptly investigate for ILD in any patient who presents with worsening of respiratory symptoms which may be indicative of ILD (e.g., dyspnea, cough and fever). Permanently discontinue TAGRISSO if ILD is confirmed [see Dosage and Administration (2.4) and Adverse Reactions (6) in full Prescribing Information]. QTc Interval Prolongation The heart rate-corrected QT (QTc) interval prolongation occurs in patients treated with TAGRISSO. Of the 411 patients in Study 1 and Study 2, one patient (0.2%) was found to have a QTc greater than 500 msec, and 11 patients (2.7%) had an increase from baseline QTc greater than 60 msec [see Clinical Pharmacology (12.2) in full Prescribing Information]. In Study 1 and 2, patients with baseline QTc of 470 msec or greater were excluded. Conduct periodic monitoring with ECGs and electrolytes in patients with congenital long QTc syndrome, congestive heart failure, electrolyte abnormalities, or those who are taking medications known to prolong the QTc interval. Permanently discontinue TAGRISSO in patients who develop QTc interval prolongation with signs/symptoms of life-threatening arrhythmia [see Dosage and Administration (2.4) in full Prescribing Information]. Cardiomyopathy Across clinical trials, cardiomyopathy (defined as cardiac failure, pulmonary edema, ejection fraction decreased or stress cardiomyopathy) occurred in 1.4% (n=11) of TAGRISSO treated patients (n=813); 0.2% (n=2) were fatal. In Study 1 and Study 2, Left Ventricular Ejection Fraction (LVEF) decline >10% and a drop to <50% occurred in 2.4% (9/375) of patients who had baseline and at least one follow-up LVEF assessment. Assess LVEF by echocardiogram or multigated acquisition (MUGA) scan before initiation of TAGRISSO and then at 3 month intervals while on treatment. Withhold treatment with TAGRISSO if ejection fraction decreases by 10% from pretreatment values and is less than 50%. For symptomatic congestive heart failure or persistent, asymptomatic LV dysfunction that does not resolve within 4 weeks, permanently discontinue TAGRISSO [see Dosage and Administration (2.4) in full Prescribing Information]. Embryo-Fetal Toxicity Based on data from animal studies and its mechanism of action, TAGRISSO can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, osimertinib caused post-implantation fetal loss when administered during early development at a dose exposure 1.5 times the exposure at the recommended human dose. When males were treated prior to mating with untreated females, there was an increase in preimplantation embryonic loss at plasma exposures of approximately 0.5-times those observed in patients at the 80 mg dose level. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TAGRISSO and for 6 weeks after the final dose. Advise males with female partners of reproductive potential to use effective contraception for 4 months after the final dose [see Use in Specific Populations (8.1), (8.3) and Clinical Pharmacology (12.3) in full Prescribing Information]. ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Interstitial Lung Disease/Pneumonitis [see Warnings and Precautions (5.1) in full Prescribing Information] QTc Interval Prolongation [see Warnings and Precautions (5.2) in full Prescribing Information] Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data described below reflect exposure to TAGRISSO (80 mg daily) in 411 patients with EGFR T790M mutation-positive non-small cell lung cancer who received prior EGFR TKI therapy, in two single-arm studies, Study 1 and Study 2. Patients with a past medical history of ILD or radiation pneumonitis that required steroid treatment, serious arrhythmia or baseline QTc interval greater than 470 ms were excluded from Study 1 and Study 2. Baseline patient and disease characteristics were: median age 63 years, 13% of patients were 75 years old, female (68%), White (36%), Asian (60%), metastatic (96%), sites of brain metastases (39%), World Health Organization (WHO) performance status of 0 (37%) or 1 (63%), 1 prior line of therapy [EGFR-TKI treatment only, second line, chemotherapynaïve (31%)], 2 or more prior lines of therapy (69%). Of the 411 patients, 333 patients were exposed to TAGRISSO for at least 6 months; 97 patients were exposed for at least 9 months; however, no patient was exposed to TAGRISSO for 12 months. In Studies 1 and 2, the most common (>20%) adverse reactions (all grades) observed in TAGRISSO-treated patients were diarrhea (42%), rash (41%), dry skin (31%), and nail toxicity (25%). Dose reductions occurred in 4.4% of patients treated with TAGRISSO. The most frequent adverse reactions that led to dose reductions or interruptions were: electrocardiogram QTc prolonged (2.2%) and neutropenia (1.9%). Serious adverse reactions reported in 2% or more patients were pneumonia and pulmonary embolus. There were 4 patients (1%) treated with TAGRISSO who developed fatal adverse reactions of ILD/pneumonitis. Other fatal adverse reactions occurring in more than 1 patient included pneumonia (4 patients) and CVA/cerebral hemorrhage (2 patients). Discontinuation of therapy due to adverse reactions occurred in 5.6% of patients treated with TAGRISSO. The most frequent adverse reactions that led to discontinuation were ILD/pneumonitis and cerebrovascular accidents/infarctions. Tables 2 and 3 summarize the common adverse reactions and laboratory abnormalities observed in TAGRISSO-treated patients.

DRUG INTERACTIONS Effect of Other Drugs on Osimertinib Strong CYP3A Inducers Coadministering TAGRISSO with a strong CYP3A4 inducer decreased the exposure of osimertinib compared to administering TAGRISSO alone [see Clinical Pharmacology (12.3) in full Prescribing Information]. Decreased osimertinib exposure may lead to reduced efficacy. Avoid coadministering TAGRISSO with strong CYP3A inducers (e.g., phenytoin, rifampin, carbamazepine, St. John s Wort) [note: effect of St. John s Wort varies widely and is preparation-dependent]. Increase the TAGRISSO dosage when coadministering with a strong CYP3A4 inducer if concurrent use is unavoidable [see Dosage and Administration (2.4) in full Prescribing Information]. No dose adjustments are required when TAGRISSO is used with moderate and/or weak CYP3A inducers. Effect of Osimertinib on Other Drugs Coadministering TAGRISSO with a BCRP substrate increased the exposure of the BCRP substrate compared to administering the BCRP substrate alone [see Clinical Pharmacology (12.3) in full Prescribing Information]. Increased BCRP substrate exposure may increase the risk of exposure-related toxicity. Monitor for adverse reactions of the BCRP substrate (e.g., rosuvastatin, sulfasalazine, topotecan), unless otherwise instructed in its approved labeling, when coadministered with TAGRISSO. USE IN SPECIFIC POPULATIONS Pregnancy Risk Summary Based on data from animal studies and its mechanism of action, TAGRISSO can cause fetal harm when administered to a pregnant woman. There are no available data on TAGRISSO use in pregnant women. Administration of osimertinib to pregnant rats was associated with embryolethality and reduced fetal growth at plasma exposures 1.5 times the exposure at the recommended human dose [see Data]. Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically-recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data When administered to pregnant rats prior to embryonic implantation through the end of organogenesis (gestation days 2-20) at a dose of 20 mg/kg/day, which produced plasma exposures of approximately 1.5 times the clinical exposure, osimertinib caused postimplantation loss and early embryonic death. When administered to pregnant rats from implantation through the closure of the hard palate (gestation days 6 to 16) at doses of 1 mg/kg/day and above (0.1-times the AUC observed in patients at the recommended dose of 80 mg), an equivocal increase in the rate of fetal malformations and variations was observed in treated litters relative to those of concurrent controls. When administered to pregnant dams at doses of 30 mg/kg/day during organogenesis through lactation Day 6, osimertinib caused an increase in total litter loss and postnatal death. At a dose of 20 mg/kg/day, osimertinib administration during the same period resulted in increased postnatal death as well as a slight reduction in mean pup weight at birth that increased in magnitude between lactation days 4 and 6. Lactation Risk Summary There are no data on the presence of osimertinib in human milk, the effects of osimertinib on the breastfed infant or on milk production. Administration to rats during gestation and early lactation was associated with adverse effects, including reduced growth rates and neonatal death [see Use in Specific Populations (8.1) in full Prescribing Information]. Because of the potential for serious adverse reactions in breastfed infants from osimertinib, advise a lactating woman not to breastfeed during treatment with TAGRISSO and for 2 weeks after the final dose. Females and Males of Reproductive Potential Contraception Females Advise females of reproductive potential to use effective contraception during treatment with TAGRISSO and for 6 weeks after the final dose [see Use in Specific Populations (8.1) in full Prescribing Information]. Males Advise male patients with female partners of reproductive potential to use effective contraception during and for 4 months following the final dose of TAGRISSO [see Nonclinical Toxicology (13.1) in full Prescribing Information]. Infertility Based on animal studies, TAGRISSO may impair fertility in females and males of reproductive potential. The effects on female fertility showed a trend toward reversibility. It is not known whether the effects on male fertility are reversible [see Nonclinical Toxicology (13.1) in full Prescribing Information]. Pediatric Use The safety and effectiveness of TAGRISSO in pediatric patients have not been established. Geriatric Use One hundred eighty-seven (45%) of the 411 patients in clinical trials of TAGRISSO were 65 years of age and older, and 54 patients (13%) were 75 years of age and older. No overall differences in effectiveness were observed based on age. Exploratory analysis suggests a higher incidence of Grade 3 and 4 adverse reactions (32% versus 25%) and more frequent dose modifications for adverse reactions (23% versus 17%) in patients 65 years or older as compared to those younger than 65 years. Renal Impairment No dose adjustment is recommended in patients with mild [creatinine clearance (CLcr) 60-89 ml/min, as estimated by the Cockcroft Gault method (C-G)] or moderate (CLcr 30-59 ml/min, as estimated by C-G) renal impairment. There is no recommended dose of TAGRISSO for patients with severe renal impairment (CLcr <30 ml/min) or end-stage renal disease [see Clinical Pharmacology (12.3) in full Prescribing Information]. Hepatic Impairment No dose adjustment is recommended in patients with mild hepatic impairment [total bilirubin less than or equal to upper limit of normal (ULN) and AST greater than ULN or total bilirubin between 1.0 to 1.5 times ULN and any AST]. There is no recommended dose for TAGRISSO for patients with moderate or severe hepatic impairment [see Clinical Pharmacology (12.3) in full Prescribing Information].

2016 BUSINESS MEETING MINUTES TUESDAY, MARCH 15, 2016 WASHINGTON STATE CONVENTION CENTER, HALL 4E 3:30 PM 5:00 PM 2016 The program preliminary to the Annual Business Meeting opened at 3:41pm with video interviews by several key USCAP faculty members addressing Next Generation Learning. The President, John Goldblum, M.D. and the Executive Vice-President, David B. Kaminsky, M.D. were introduced. Dr. Goldblum thanked everyone for attending and then discussed how USCAP is conscious of changes in the way medical professionals learn. The traditional classroom teaching style is no longer the preferred method, particularly for millennial pathologists, who relate more to interactive, digital, on demand methodologies to grow their medical knowledge. Dr. Kaminsky spoke on the clinical implications of our knowledge and refining communication style, how we educate to meet the demands of how we learn. Video interviews with key USCAP faculty members underscored the importance of the paradigm shift in the ways new learners can receive access to knowledge and interactive learning. The Interactive Center is a prime example of how USCAP is leading the way to this new method of learning. The importance of the microscope is crucial in the learning of a pathologist. A video of the transformation of the Powers-Sanchez Interactive Center and Linder Learning Center was presented. Dr. Kaminsky described the construction of the Linder Learning Center and how it completes USCAP s vision of delivering education by a variety of versatile methods utilizing the broadcast studio and conference theater. USCAP s segment on The Discovery Channel s television series, Innovations was screened following introduction by Dr. Kaminsky. USCAP won the Silver Telly Award, Telly s highest honor. Dr. Goldblum described the process over the past year to create a more aesthetic and functional website with enhanced connectivity, representing USCAP s Smart Network. He then described creation of the Social Media Sub-committee under the leadership of Dr. Jerad Gardner, which energetically responds to the social demands of our members. Dr. Kaminsky described the redesign of the Ambassador program to attract pathologists-in-training to serve as diplomats for USCAP and propel them through their career tracks. He announced creation of the President s Helix, a group of Past-Presidents with historical wisdom, who desired to reconnect with the modern Academy. 1. CALL TO ORDER DR. JOHN R. GOLDBLUM The formal 2016 USCAP Business Meeting was called to order by Dr. Goldblum on Tuesday March 15, 2016 at 4:07 pm. 2. ADOPTION OF AGENDA DR. JOHN R.

SCHEDULE & GENERAL INFO 2016 BUSINESS MEETING MINUTES 6. REPORT OF THE EDUCATION COMMITTEE DR. LAURA LAMPS Dr. Laura Lamps presented a summary of the 2016 Annual Meeting Statistics. There were 4,709 registrants from 84 countries. She stated that 3,054 abstracts were submitted with 2,096 accepted: an acceptance rate of 69%; these were triaged to 1,816 posters and 280 platform presentations. Dr. Lamps enumerated that the total number of possible CME s per person is 55.5 hours and SAMs per person 52.5 hours. She explained the excitement surrounding the new digital products, Interactive Microscopy, the Interactive Center, the opportunity to enhance mentoring and a reinvigorated subcommittee on Informatics. Dr. Lamps ended with a slide on a Formula for Success, which contained all the above-referenced totals. 7. REPORT OF THE FINANCE COMMITTEE DR. WENDY FRANKEL Financial success allows the USCAP to build its future, with investments like the interactive learning center and redesigned website. This growth and diversification of the Academy represents positive change, strengthening our ability to serve our members. A collective effort among the USCAP of Directors, Committees, and Management team working collaboratively resulted in USCAP s achieving strong financial metrics, developing a strong financial position and reinforcing USCAP as the most prestigious provider of continuing medical education for pathologists globally for many years to come. The combined revenues of the Academy totaled $7.2 million last fiscal year with more than 85% directed to fund USCAP programs for our customers and members. With a strong investment portfolio, primarily consisting of a diverse mix of mutual funds, treasury notes and bonds, we continue to achieve our annual targeted rate of return. In November 2015, auditors released their annual report on the Academy finances, which included no errors in management s presentation of the financial statements. 8. REPORT OF THE MEMBERSHIP/RAC COMMITTEES DR. TARIK TIHAN Dr. Tihan thanked the committee members and Dr. Kaminsky for their assistance over the last two years. He explained the structure and terms of the Membership Committee by presenting a list of the committee members. The bylaws change ratified the previous year (re-structuring member categories) has allowed over 70 Ph.D. colleagues to become members of USCAP. The creation of the Membership Passport is encouraging members for life. Dr. Tihan spoke on the revamping of the Ambassador program and he thanked the dedicated staff member Debbie Waterhouse. To assist with additional media support, the creation of the Social Media Sub-committee was developed under the supervision of Dr. Jerad Gardner. Dr. Tihan provided the attendees with graphical representations of the membership database and the demographics of the distribution of the membership. Priorities for 2016 include gathering member demographic data by mining the database, surveys, engaging clinical pathologists, creating members for life, continuing support for the Resident Advisory Sub-committee and Social Media committee, developing a member gift program and assisting the Executive Vice-President with the Ambassador program. 9. REPORT OF THE USCAP FOUNDATION DR. GREG FULLER Dr. Fuller thanked the Foundation Committee for their dedication in making this another successful year for the USCAP Foundation. The Foundation has adopted the goal of improving health globally by leveraging the power of philanthropy. The priorities of the Foundation are innovating education, fostering new pathologists and promoting global health. Dr. Fuller further described the importance of the Interactive Center and how the Foundation would play an integral role in its financial support. He reinforced mentorship as a key core value. Dr. Fuller described the several on-going initiatives of the Foundation such as partnering with the Cleveland Clinic and Yale for the multi-week clerkship for three young pathologists from Haiti, Paraguay, and Nepal; the Miles-for-Mentors cross-fit edition which was a success (Yoga was proposed for 2017 in San Antonio); provision of travel grants to ten pathologists-in-training to attend the Annual Meeting; and transforming the G20 2015 program to the G40 2016 program to provide travel scholarships to 40 pathologists from underserved countries who would not have otherwise had the opportunity to attend the meeting. The Foundation continues to support the West African school and thanked the ASCP for their collaboration on the Africa Calls initiative. Dr. Fuller thanked Dr. Hardwick for the creation of the USCAP Canada Foundation to allow Canadians an opportunity to make tax deductible contributions in support of the educational mission of the USCAP. 31

COMPANION MEETINGS COMPANION SOCIETY MEETING AMERICAN ASSOCIATION OF NEUROPATHOLOGISTS Pineal Region Tumors SATURDAY, MARCH 4, 2017 7:00 PM 10:00 PM CC 221 A-C MODERATORS: Christine Fuller, MD, Cincinnati Children s Hospital Medical Center, Cincinnati, OH Adekunle Adesina, MD, PhD, Baylor University, Texas Children s Hospital, Houston, TX COURSE DESCRIPTION: To address the difficult and challenging issues that can be encountered by both the practicing surgical pathologists and neuropathologists alike. The regional approach will facilitate the understanding of the practical issues and differential diagnostic problems that arise in actual practice. Many practicing pathologists encounter surgical neuropathology specimens and are in a position to provide intraoperative consultations and final diagnoses on a broad spectrum of neurosurgical specimens, while they are not necessarily trained in the field of neuropathology. These talks will provide a framework for them to formulate their work-up and diagnoses, while educating them on the intricacies and pitfalls of various tumors seen in the pineal region. Upon completion of this educational activity, participants should be able to: Describe the classification of pineal parenchymal tumors and WHO grading Identify the major tumors encountered in the pineal region and their differential diagnosis Effectively avoid pitfalls arising from the unusual histologic appearances inherent to the pineal region Become familiar with the tumors with papillary features arising in the pineal region 7:00 PM OPENING REMARKS Christine Fuller, MD, Cincinnati Children s Hospital Medical Center, Cincinnati, OH Adekunle Adesina, MD, PhD, Baylor University, Texas Children s Hospital, Houston, TX 7:10 PM PINEAL PARENCHYMAL TUMORS Tarik Tihan, MD, PhD, University of California San Francisco, San Francisco, CA 7:50 PM GERM CELL TUMORS Eyas Hattab, MD, University of Louisville, Louisville, KY 8:30 PM PAPILLARY TUMOR OF THE PINEAL REGION AND THE DIFFERENTIAL DIAGNOSIS OF PAPILLARY TUMORS Brent Orr, MD, PhD, St. Jude Children s Research Hospital, Memphis, TN 9:10 PM PINEAL CYST, GLIAL AND OTHER RARE TUMORS Hannes Vogel, MD, Stanford University Medical Center, Stanford, CA 41

COMPANION MEETINGS COMPANION SOCIETY MEETING ASSOCIATION FOR PATHOLOGY INFORMATICS The March Towards Precision Medicine: Value of Pathology Informatics in Creation of Pixel and Genome Pipelines to Enhance the Diagnostic Process SATURDAY, MARCH 4, 2017 7:00 PM 10:00 PM CC 221 D MODERATOR: Anil Parwani, MD, PhD, MBA, The Ohio State Universality, Columbus, OH COURSE DESCRIPTION: Digital pathology, image-based and genomic analytics is being increasingly appreciated as a critical area of pathology practice. The goal of the symposium is to present several aspects of digital pathology, next generation sequencing and image based analytics, and to apply these approaches too current and future pathology practice. As digital pathology and next generation sequencing becomes more mainstream, pathologists and pathologists in training need to not only understand the applications of these new technologies in routine practice, but how these technologies will change the pathology practice. Topics will focus on creating pipelines of image and genomic data through advanced techniques such as digital imaging and next generation sequencing. Focus will also be on leveraging data analytics utilizing both genomic and digital image pipelines. Very little exposure to these concepts is available in most pathology practices. In summary, this symposium will provide useful insights into the creation of pipelines of information from images and genomic sequencing and how these pipelines require an understanding of pathology informatics in providing solution, robust infrastructure and analytical tools. Upon completion of this educational activity, participants should be able to: Have a greater familiarity with the most recent advancement in the growing field of Digital Pathology and image analysis Understand the requirements for next generation sequencing of pathology specimens and system implementation Understand the opportunities afforded by the availability of digital pathology for computational analysis and creation of decision support analytical tools Apply concepts of digital image analysis to clinical practice and research such as multiplex analysis of pathology samples Present practical examples of next generation sequencing applications and the support of clinical diagnosis and precision medicine 7:00 PM INTRODUCTION AND SYMPOSIUM OVERVIEW: EMERGING TRENDS IN PATHOLOGY INFORMATICS Anil Parwani, MD, PhD, MBA, The Ohio State University, Columbus, OH 7:15 PM RE-IMAGINING THE MICROSCOPE TO FACILITATE COLLABORATION AND INTEGRATION OF BIG DATA IN MEDICINE Bruce Levy, MD, CPE, Geisinger Health System, Danville, PA 8:00 PM CREATION OF A PIXEL PIPELINE AND THE NEED FOR IMAGE ANALYSIS TO IMPROVE WORKFLOW AND INCREASE ADOPTION OF DIGITAL PATHOLOGY FOR CLINICAL USE Andrew J.

Lloyd, MD, PhD, The University of Wisconsin, Madison, WI COURSE DESCRIPTION: Ki67 labeling index (LI) has been established as the reliable method of demonstrating the proliferative activity of tumor cells and is replacing classical mitotic index in potential classification, prediction of clinical outcome and therapeutic response to adjuvant or neoadjuvant therapy and others. Therefore, the exact value of Ki67 LI has been frequently asked by clinical oncologists managing the patients with cancer patients. In particular, among endocrine neoplasms, Ki67 LI plays indispensable roles in surgical pathology diagnosis of neuroendocrine neoplasms in pancreas, GI tract and lung, pituitary tumors and adrenal neoplasms, especially adrenocortical carcinoma. However, it is also true that the methodology of obtaining Ki67 LI has not been standardized especially in where to be evaluated, hot spots versus average and how to be counted, eye ball versus computer assisted image analysis. Therefore, in this companion symposium, the value and pitfalls of Ki67 labeling index will be summarized in lung, pancreas and GI tract neuroendocrine neoplasms, pituitary tumors and adrenal neoplasms. Upon completion of this educational activity, participants should be able to: Describe the importance and limitations of Ki67 labeling index in endocrine tumors including the value of threshold in discerning malignancy in individual endocrine tumors, possible overlap between benign and malignant endocrine tumors, its value as surrogate markers for adjuvant and neoadjuvant therapy in specific endocrine tumors Identify the threshold of Ki67 labeling index for discerning malignancy in endocrine tumors according to WHO classification and other guidelines. The proposed threshold of Ki67 LI in selecting specific medical therapy in endocrine neoplasms to communicate with clinical oncologists or endocrinologists. The importance of standardization of Ki67 LI as well as its limitations Incorporate the absolute Ki67 labeling index number in surgical pathology report of endocrine neoplasms including the methodology of immunostaining and scoring 7:00 PM INTRODUCTION: KI67; AVERAGE VERSUS HOT SPOTS; EYE BALL VERSUS IMAGE ANALYSIS Hironobu Sasano, MD, PhD, Tohoku University School of Medicine, Sendai, Japan 7:15 PM KI67 IN PANCREATIC NEN OR NEUROENDOCRINE NEOPLASM ACCORDING TO WHO 2017 Günter Klöppel, MD, PhD, Consultation Center for Pancreatic and Endocrine Tumors, München, Germany 7:45 PM KI67 IN PITUITARY TUMORS: WHAT INFORMATION COULD WE OBTAIN?

COMPANION MEETINGS COMPANION SOCIETY MEETING ARTHUR PURDY STOUT SOCIETY OF SURGICAL PATHOLOGISTS There Are No Magic Bullets: When Immunostains Can Get You Into Trouble SUNDAY, MARCH 5, 2017 8:30 AM 12:00 PM CC HEMISFAIR 2 & 3 MODERATORS: Vania Nosé, MD, PhD, Massachusetts General Hospital, Harvard Medical School, Boston, MA Rhonda Yantiss, MD, PhD, Weill Cornell Medicine, New York, NY COURSE DESCRIPTION: Pathologists increasingly rely upon ancillary techniques, particularly immunohistochemistry, to facilitate or render diagnoses. While these stains work well in narrowing down a differential diagnosis, results can also generate confusion, particularly when pathologists utilize reflexive immunohistochemical stain panels for the evaluation of specific tumor types. Many tumors show aberrant, or unexpected expression of markers that can lead to erroneous diagnoses. For example, CD138 is generally considered to be a marker of plasma cell differentiation, although this antibody can also stain a variety of other types of plasmacytoid tumor, including gastrointestinal stromal tumors. Pleomorphic sarcomas that show epithelioid morphology often express keratins, and some lymphomas can be negative for CD45. The purpose of this session is to discuss common immunohistochemical pitfalls that can lead to diagnostic errors. Upon completion of this educational activity, participants should be able to: Describe a rationale for ordering immunohistochemical stains for the classification of soft tissue tumors Identify diagnostic problems introduced by immunohistochemical staining patterns that are not entirely specific Measure overall stain utilization in their own practices 8:30 AM INTRODUCTION Vania Nosé, MD, PhD, Massachusetts General Hospital, Boston, MA Rhonda Yantiss, MD, PhD, Weill Cornell Medical College, New York, NY 8:35 AM PRESIDENT S AWARD 8:45 AM GENITOURINARY PATHOLOGY Jesse McKenney, MD, Cleveland Clinic, Cleveland, OH 9:10 AM GASTROINTESTINAL PATHOLOGY John Hart, MD, University of Chicago, Chicago, IL 9:35 AM HEMATOPATHOLOGY Judith Ferry, MD, Massachusetts General Hospital, Boston, MA 10:00 AM BREAK 10:30 AM PRIZE 10:40 AM GYNECOLOGIC PATHOLOGY Teri Longacre, MD, Stanford University, Stanford, CA 11:05 AM SOFT TISSUE PATHOLOGY Andrew Folpe, MD, Mayo Clinic, Rochester, MN 11:30 AM NEUROENDOCRINE TUMORS David Klimstra, MD, Memorial Sloan-Kettering Cancer Center, New York, NY 47

Khoury, MD, University of Texas MD Anderson Cancer Center, Houston, TX Larissa V. Furtado, MD, FCAP, University of Utah/ARUP Laboratories, Salt Lake City, UT COURSE DESCRIPTION: Since 1986, the CAP Cancer Protocols have served as a resource and reference for complete reporting of malignant tumors, including American Joint Committee on Cancer (AJCC) staging and the World Health Organization (WHO) histologic type standard elements. The CAP Cancer Committee is responsible for producing and maintaining these important reference resources and cancer reporting tools. The protocols have grown in number and scope over the past several years, and have influenced important global efforts such as the International Collaboration on Cancer Reporting (ICCR) datasets. Reporting cancer elements has progressed from the traditional narrative reporting style with observed characteristics of the neoplastic cells to more highly arranged synoptic reports that better optimize readability with computer reporting systems. The current drive to develop structured reporting for cancer attempts to organize the data elements in the synoptic field to integrate with the laboratory information system (LIS) and then with the electronic medical record (EMR). The CAP Cancer Protocols are intended to: 1) support pathologists in generating complete reports that contain all the core data elements, and 2) ensure that the core data elements are clear and unambiguous for clinicians. The CAP Cancer Protocols are evolving to meet the needs for greater data usage and integration as the cancer community develops new therapies and big-data research. Upon completion of this educational activity, participants should be able to: Explain the value of the cancer protocols to patient care Distinguish the difference between synoptic reporting and structured reporting and the value both bring to cancer patients Demonstrate the key changes to the staging elements with the AJCC 8th edition Cancer Staging Manual (TNM) 8:30 AM INTRODUCTION Joseph D.

A continuing rise in the identification of cancer-causing germline mutations for which molecular testing is available, coupled with a heightened awareness of the importance of a detailed family history for sarcoma patients, has improved diagnosis, prevention, surveillance, and therapy for affected families. The genetic breakthroughs that have resulted from the investigation of inherited cancer syndromes have not only benefited patients with heritable tumor predisposition but have also shed light on the regulatory molecular pathways in sporadic tumors thereby advancing the care of sarcoma patients without known risk factors too. These discoveries continue to expand the role of the surgical pathologist in the multidisciplinary care of patients with these neoplasms. In this companion meeting, new developments as well as current principles of molecular and surgical pathology in bone and soft tissue tumors (heritable and sporadic counterparts) and their application to the clinical management of these neoplasms will be emphasized. The symposium theme and content are selected by the President with input from the executive officers of the International Society of Bone and Soft Tissue Pathology. The agenda has been designed to meet the educational needs of general surgical pathologists as well as bone and soft tissue tumor subspecialists who are involved in the management of patients with mesenchymal neoplasms.

The project was undertaken because of discussions that occurred while updating the most recent edition of the WHO blue book on the Diagnosis of Gynecologic Neoplasms. Experts felt that there were significant inconsistencies in terminology and criteria for the diagnosis of endometrial carcinoma around the world. It was also felt that there was need to update the currently used criteria to include recent advances in the understanding of molecular events in endometrial carcinoma. The ISGyP sponsored a broad project which included conducting a survey of the membership of the ISGyP to identify areas of controversy and confusion in the diagnosis of endometrial carcinoma. A conference was subsequently convened in Seattle in 2016, where discussion occurred and where possible guidelines were vetted and standardized criteria proposed. This conference will discuss the culmination of those efforts and will present those guidelines and recommendations, which will be published in 2017 in the International Journal of Gynecological Pathology. Upon completion of this symposium, participants should be better able to: Define the most useful histological features and immunohistochemical stains to diagnose clear cell carcinoma of the endometrium Identify the patterns of mixed endometrial cancer and distinguish them from diagnostic mimics Describe strategies for classifying high grade endometrial carcinoma into clinically relevant categories Determine how to assess staging parameters in endometrial carcinoma Describe the standardized grossing of tissues removed for the diagnosis and staging of endometrial carcinoma Describe the recent developments in the molecular classification of endometrial carcinoma 1:30 PM RATIONALE AND BACKGROUND FOR THE ISGYP ENDOMETRIAL CARCINOMA PROJECT Vinita Parkash, MBBS, Yale University School of Medicine, New Haven, CT 1:40 PM THE DIAGNOSIS OF MIXED CARCINOMA OF THE ENDOMETRIUM Joseph Rabban, MD, MPH, University of California San Francisco, San Francisco, CA 2:05 PM STRATEGIES FOR CLASSIFYING ENDOMETRIAL CARCINOMA WITH CLEAR CELLS Oluwole Fadare, MD, University of California San Diego, San Diego, CA 2:35 PM STRATEGIES FOR TYPING HIGH GRADE ENDOMETRIAL CARCINOMA Blake Gilks, MD, Vancouver General Hospital, Vancouver, BC 3:05 PM BREAK 3:30 PM ISGYP AWARD CEREMONY W.

SPECIAL COURSES SPECIAL COURSE Molecular Diagnostic and Genomic Applications in Cancer: A Primer for the Pathologist TUESDAY, MARCH 7, 2017 8:00 AM 5:15 PM CC HEMISFAIR 2 COURSE DIRECTORS: George J. Netto, MD, The University of Alabama at Birmingham, Birmingham, AL Karen Kaul, MD, PhD, North Shore University Health System, Evanston, IL COURSE DESCRIPTION: The pathologist is increasingly expected to play a central role in the management of cancer patients in the era of personalized oncology. Molecular diagnostic and genomic applications are rapidly penetrating the daily practice of the pathologist as the list of actionable genetic alteration in solid and hematologic tumors continues to expand. As highlighted in the USCAP 2012 combined companion meeting of the Association for Molecular Pathology Joint Meeting with American Society for Clinical Pathology in Coordination with American Society for Investigative Pathology, efforts to develop residency curricula that will address the educational needs in molecular and genomic pathology for pathologists in training are underway by some academic institutions and others. These initiatives include the efforts sponsored by the Training Residents in Genomics (TRIG) working group of the Pathology Residency Directors Section of the Association of Pathology Chairs. Similar educational needs are evident among practicing pathologists in the community and academic centers, pathology residents and fellows in institutions that are yet to develop a formal curriculum. A survey of the positive responses from attendees of the sold out special course titled Basic Principles and Practice of Molecular Pathology in Cancer, which was in its final iteration at USCAP 2012, is very indicative of an urgent and important educational need. The current course proposal intends to build upon and extend the role that the latter course, that is no longer offered, fulfilled. In fact, the proposal stems from the shared recognition of the AMP, ASIP and ASCP organizations that sponsored the 2012 combined companion meeting and from the director and faculty of the previous special course that there is the continuous need to offer educational opportunities to augment medical knowledge and to address competency deficiencies among the intended target audience, which is, primarily, the group of anatomic pathologists.

LONG COURSE LONG COURSE Prostate Pathology: Practical Issues WEDNESDAY, MARCH 8, 2017 8:00 AM- 5:30 PM CC SNB 3&4 COURSE DIRECTOR: CO-DIRECTOR: Cristina Magi-Galluzzi, MD, PhD, Cleveland Clinic, Cleveland, OH Ming Zhou, MD, PhD, New York University Medical Center, New York, NY COURSE DESCRIPTION: Accurate diagnosis, Gleason grading and staging of prostate cancer, and prudent use of ancillary tests are critical for management of prostate cancer patients. However, error in diagnosing, grading and reporting prostate cancer has remained a significant problem in clinical practice, with diagnostic errors that potentially impact clinical management in 1-15% of prostate biopsies. Gleason grading system has undergone significant modification and a new grading system has been proposed, yet the adoption of these changes in clinical practice is slow. New entities of important clinical significance, such as intraductal carcinoma, have been described. There have been tremendous advances in the understanding of molecular and genetic mechanisms in prostate carcinogenesis and progression which has led to development of multigene genetic and genomic tests. However, there has been a lack of understanding of the new entities and molecular diagnostic tests among practicing pathologists. Upon completion of this educational activity, participants should be able to: Review histological criteria for diagnosing prostate cancer and use of immunohistochemistry markers. Review benign mimickers of prostate cancer and cancer that mimics benign prostate lesions. Update on recent modifications of Gleason system and the novel grading system (grade grouping). Identify the clinical relevant pathological parameters that should be included in the surgical pathology report. Learn the new advances in molecular mechanisms in prostate carcinogenesis/progression and clinically relevant genetic tests. 8:00 AM WELCOME/INTRODUCTION Cristina Magi-Galluzzi, MD, PhD, Cleveland Clinic, Cleveland, OH Ming Zhou, MD, PhD, NYU Medical Center, New York, NY 8:05 AM EPIDEMIOLOGY AND GENOMICS OF PROSTATE CANCER: AN UPDATE Mark Rubin, MD, Weill Cornell Medical College, New York, NY 8:30 AM PROSTATE CANCER: DIAGNOSTIC CRITERIA AND ROLE OF IMMUNOHISTOCHEMISTRY Cristina Magi-Galluzzi, MD, PhD, Cleveland Clinic, Cleveland, OH 8:55 AM BENIGN MIMICKERS OF PROSTATE CANCER Kiril Trpkov, MD, University of Calgary, Calgary, AB 9:25 AM QUESTIONS 9:30 AM BREAK 10:30 AM PROSTATE CANCER GRADING: FROM GLEASON TO A CONTEMPORARY NEW GRADING SYSTEM Jonathan Epstein, MD, The Johns Hopkins Medical Institute, Baltimore, MD 11:00 AM UNUSUAL VARIANTS OF ACINAR PROSTATE CANCER MIMICKING BENIGN Peter A.

THE MAUDE ABBOTT LECTURE PETER A. HUMPHREY, M.D., PH.D. 2 0 1 7 USCAP HONORS HIGH PERFORMANCE ACHIEVEMENT Dr. Peter A. Humphrey is a surgical pathologist with expertise in urologic and prostate pathology. He was born in Chicago, Illinois and earned his B.A. from the University of Kansas, where he majored in chemistry and biochemistry. In 1984 he received his M.D. degree and Ph.D. degree (in biochemistry) from the University of Kansas Medical Center, followed by anatomic pathology residency at Duke University Medical Center. During the middle of his residency he took 2 research years to work on epidermal growth factor receptor (EGFR) mutant proteins and was awarded, at a USCAP meeting, the Benjamin Castleman Award for the work, published in PNAS, on creation of an antibody specific for a deletion mutant EGFR protein expressed in glioblastomas. During residency at Duke he launched his career-long interest in urologic pathology and prostate cancer, at a time when there was a surge of national clinical interest in prostate cancer with the introduction of prostate-specific antigen (PSA) testing and more widespread utilization of radical prostatectomy. In December 1988, he joined the faculty at Duke as Assistant Professor of Pathology and in 1992 left to become Associate Professor at Washington University School of Medicine in St. Louis, where he became Full Professor and in 2006 was named the Ladenson Professor and Director of Anatomic and Molecular Pathology. In 2014 he joined the Yale School of Medicine Department of Pathology as Professor and Director of Genitourinary Pathology. Dr. Humphrey has published over 330 papers, reviews, and book chapters, with a dominant focus on genitourinary pathology and diseases of the prostate. He is sole author of the 2003 textbook Prostate Pathology, is co-author of the 2011 AFIP Fascicle on Tumors of the Prostate, is editor and co-author of the 2008 and 2012 editions of The Washington Manual of Surgical Pathology, is co-author of the 2014 textbook Neoplastic Mimics in Genitourinary Pathology, and is a volume editor and co-author of the 2016 WHO Classification of Tumours of the Urinary System and Male Genital Organs. He has lectured and given courses throughout the United States and world, including 6 of the 7 continents (with only Antarctica to go). His prostate research includes clinico-pathologic and molecular pathologic studies. Molecular pathologic studies led to publications on the role of hepatocyte growth factor (scatter factor) and its receptor, c-met in prostate cancer, and separate papers on gene expression profiling of prostatic atrophy, ductal adenocarcinoma of the prostate, and acinar prostate cancer. Surgical pathology investigations include an original description of pseudohyperplastic adenocarcinoma and characterization of additional deceptively benign appearing prostate cancers including microcystic, foamy, and atrophic adenocarcinomas. Additional papers have addressed diagnostic immunohistochemistry, prostatic intraepithelial neoplasia, screen-detected prostate cancers, and prognostic indicators of tumor extent and grade. Teaching/ medical education is a vital component of Dr. Humphrey s career. He feels fortunate to have had the opportunity to provide many courses and lectures in many different venues. He also feels privileged to have worked with so many bright residents and fellows over the years. He has won resident teaching awards at Duke University and Washington University. Dr. Humphrey first attended a United States and Canadian Academy of Pathology (USCAP) Annual Meeting as a resident and has attended and contributed to every USCAP Annual Meeting since 1987. He has served as member of the Nominating Committee, member of Council, member of the Abstract Review, and member of the Education Committee. He has been moderator of numerous platform sessions, has helped give two short courses, and co-directed the 2003 Long Course on Prostate. The United States and Canadian Academy of Pathology has been crucial in Dr. Humphrey s career development. He is honored to provide the 2017 Maude Abbott Lecture. 107

HARVEY GOLDMAN MASTER TEACHER OF THE YEAR AWARD STEVEN H. SWERDLOW, M.D. 2 0 1 7 USCAP HONORS HIGH PERFORMANCE ACHIEVEMENT Dr. Steven Swerdlow recognized his destiny at a young age. A workbook page entitled My Plans for the Future drawn in third grade shows him seated looking through a microscope with a pair of glasses and a mouse in a cage at his side! A graduate of Brandeis University and Harvard Medical School, he did his AP/CP training at Beth Israel Hospital in Boston, followed by a hematopathology fellowship with R. D. Collins and then a research fellowship at St. Bartholomew s Hospital in London. After nine years at the University of Cincinnati, he joined the University of Pittsburgh where he is Professor of Pathology and Hematopathology Division Director. Dr. Swerdlow is an accomplished hematopathologist and dedicated educator. His clinical work has been recognized with inclusion in America s Top Doctors and Best Doctors in America. His investigative efforts have concentrated on B-cell lymphomas (eg, with M. Williams helped establish the genetic basis of mantle cell (centrocytic) lymphoma), and to a lesser extent on T/NK-cell neoplasms, cutaneous lymphomas and the post-transplant lymphoproliferative disorders. He was involved in developing the WHO-EORTC classification of cutaneous lymphomas, lead editor for the 2008 WHO monograph on Classification of Tumours of Haematopoietic and Lymphoid Tissues and is lead editor for the 2016/2017 revision. He has >200 peer-reviewed publications, and published numerous chapters, a lymph node pathology text, and co-edited a pediatric hematopathology text. These accomplishments have led to many invited lectures around the world and the inaugural Society for Hematopathology (SH) Berard-Dorfman Founders Award for a senior hematopathologist (2015). He is an American of Pathology trustee, an ACGME Pathology Review Committee member; and, former USCAP council member, SH President, EAHP Executive Committee member, and Pittsburgh Pathology Society President. His lectures are known for their educational content, visual interest and entertaining qualities. He has received three resident teaching awards and has provided courses, helped organize slide workshops and provided other educational and special lectures for the USCAP (5 short courses, 2 long courses including one as co-director, and Diagnostic Pathology faculty) and numerous other organizations/institutions. He is grateful to the USCAP for its critical role in promoting his career. Of those from the old days, only Carolyn Lane remains, but Jo Ann Johnson, Jim Crimmins, and Fred Silva will never be forgotten. This award is of particular significance to Dr. Swerdlow because of his personal connection to Dr. Harvey Goldman admiring him as a teacher in medical school, and as an important mentor during his residency. Although he knows he drove Dr. Goldman crazy since he was unable to keep up a conversation about the Boston Red Sox while signing out together over the summer, he remained a friend until the end. Dr. Goldman, along with Dr. Donald Antonioli, worked with Dr. Swerdlow on his first classification project, one related to dead bowels, not lymphomas. Receiving this award would have pleased Dr. Swerdlow s father, an academic pathologist and winner of multiple Golden Apple teaching awards, and is a source of joy for his 92-year-old mother. Finally, he is grateful for the support of his wife Jenny, daughters Debbie (son-in-law Scott and granddaughter Mia) and Naomi. Many years ago, Naomi wrote that If you don t know what slides are, they have a picture on it and you put one in a thing you turn on the fwockis[sic] and look throw[sic] and see a neat picture and Debbie that The job of being a pathologist (a kind of doctor) is quite hard. Like most doctors, they try to cure people. Nothing more needs to be said. 5

2 0 1 7 USCAP HONORS HIGH PERFORMANCE ACHIEVEMENT THE RAMZI S. COTRAN YOUNG INVESTIGATOR S AWARD ANTHONY J. GILL, MBBS, FRCPA, M.D. Dr. Anthony Gill was born at Royal North Shore Hospital in Sydney in the old maternity unit, not more than 20 meters from the location of his current office and laboratory. He attended the Shore School on a full academic scholarship where he was dux and prefect before progressing to fulfilling his childhood dream to study medicine (MBBS) at the University of Sydney. He graduated with the Royal North Shore Hospital Medal and prizes for first in the university in both Medicine and Surgery in 1996. His postgraduate training included clinical years as an intern, resident and registrar in both internal medicine and emergency. Almost on a whim in 2000 he commenced training in the dark arts of Anatomical Pathology at Royal North Shore Hospital under the tutelage of pathologists whom he greatly respects including Judith Fryer, Jeanette Philips and Roberts Eckstein. He was immediately entranced by the ability of dedicated and highly trained pathologists to make critical decisions and directly and dramatically help patients on a daily basis, often despite minimal community recognition. During his training he had the opportunity to learn at Royal Prince Alfred Hospital, the Children s Hospital Westmead and the NSW Institute of Forensic Medicine. He qualified FRCPA in 2005 and commenced practice as a staff specialist at Royal North Shore Hospital with special interest in endocrine, gastrointestinal and pancreaticobiliary pathology. He also commenced translational research in surgical pathology gravitating towards the areas of endocrine and pancreaticobiliary pathology primarily because it was in these areas that he encountered particularly passionate and dedicated clinical and laboratory teams. He was awarded a higher doctorate by publication by the University of Sydney in 2011 and promoted to Associate Professor in 2012. Seeing a strong need for pathologists to not just contribute to translational research in clinical fields and the basic sciences, but also to be given the opportunity to undertake pathologistdirected research explicitly in the field of surgical pathology, he founded the Cancer Diagnosis and Pathology website www.cancerdxpathology.org.au with a mission to facilitate research by surgical pathologists in surgical pathology. He has published extensively both within the structure of this group and in major international collaborations including the International Cancer Genome Consortium (ICGC) where he was a key member of the Australian Pancreatic Genome Initiative, initially as lead pathologist and now as chairman. He was awarded a personal chair as Professor of Surgical Pathology at the University of Sydney in 2016. Dr Gill has co-authored more than 240 original research publications (more than one quarter as senior scientific author) but is particularly proud of his work in the field of succinate dehydrogenase deficient neoplasia. While he fully acknowledges the work of many other research groups in this very active field, his work has been crucial to the widespread recognition of both succinate dehydrogenase deficient GIST and succinate dehydrogenase deficient renal cell carcinoma as unique entities with profound clinical significance. He has been a co-author of 10 WHO Blue Book chapters across three different books and was a member of the WHO Consensus Committee which met in Lyons, France (April 26 28 2016) to finalize the 4th Edition 2017 Genetics of Tumour of Endocrine Organs. He is grateful for the recognition that his work has achieved including the 2011 Benjamin Castleman Award from USCAP, the 2014 NSW Premier s Award for excellence in Translational Cancer Research and the NSW Cancer Institute Wildfire Award (twice). 6 He is particularly grateful to his surgical pathology collaborators and mentors. He has always felt welcomed by the international community of pathologists from around the world and, in particular, by USCAP.

BENJAMIN CASTLEMAN AWARD CARLOS A. MURGA-ZAMALLOA, M.D. 2 0 1 7 USCAP HONORS HIGH PERFORMANCE ACHIEVEMENT Dr. Carlos A. Murga-Zamalloa was born in Lima, Peru. He received his M.D. degree from San Martin de Porres University, Lima. Subsequently, he completed two postdoctoral trainings at the University of Michigan in Dr. Anand Swaroop s and Dr. Megan Lim s laboratories. In 2015, he completed his Anatomic and Clinical Pathology Residency at the University of Michigan and is currently a Hematopathology Fellow at the University of Michigan. Dr. Murga-Zamalloa has published 24 peer-reviewed manuscripts, one third of them as first-author. His current work focuses on the pathogenesis of T-cell lymphomas and specifically on the role of actin-related signaling networks during the development and progression of these types of tumors. His most recent work has demonstrated the role of Wiskott-Aldrich syndrome protein (WASp) in regulating the oncogenesis of anaplastic large cell lymphoma. Dr. Murga-Zamalloa has been the recipient of the 2014 Hematological Opportunities for the Next Generation of Research Scientists (HONORS) Award from the American Society of Hematology (ASH) and the 2015 Stowell-Orbison Award Certificate of Merit from the United States and Canadian Academy of Pathology (USCAP). He is currently working under the mentorship of Dr. Ryan Wilcox and Dr. Stephen Weiss at the University of Michigan. 7

DR. L. CLARKE JR. & ELAINE F. STOUT ENDOWMENT AWARD NATALIA RUSH, M.D. 2 0 1 7 USCAP HONORS HIGH PERFORMANCE ACHIEVEMENT Dr. Natalia Rush is a pathologist-in-training in the Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis. She earned her Medical Degree from Indiana University School of Medicine and Bachelor of Science in Biomedical Engineering from Illinois Institute of Technology, Chicago. Her academic interests are hepatic, gastrointestinal, and solid organ transplant pathology. Dr. Rush enjoys academic research and will continue her training as a fellow in liver and gastrointestinal pathology at Indiana University School of Medicine. Dr. Romil Saxena is her mentor who shaped her interests in hepatic and gastrointestinal pathology; together they have worked on several interesting clinicopathologic research projects. One such project led to the paper Hepatic arterial buffer response: pathologic evidence in non-cirrhotic human liver with extrahepatic portal vein thrombosis published in Modern Pathology (2016; 29:489-99), for which Dr. Rush is being honored by USCAP s 2017 Dr. L Clarke Jr. and Elaine F. Stout Award. Intricacies of the hepatic microvasculature and sophistication of its compensatory mechanisms make the study of hepatic vascular physiology and hepatic vascular diseases particularly challenging in human subjects. The hepatic arterial buffer response has been well documented in animals and has been demonstrated during surgery by imaging modalities in human subjects, but has persistently defied pathologic study. Using time honored principles of histopathologic observations and morphometric analyses, Dr. Rush and colleagues have provided pathologic evidence of a compensatory hepatic vascular physiologic response that is essential for maintaining whole body homeostasis. Their paper thus honors the Dr. L Clarke Jr. and Elaine F. Stout Award s founding principle of solving a medical problem based on anatomic studies. 9
