Current Policy Statement Health Net Inc., considers the following tumor markers medically necessary for the diagnosis and/or management of cancer (more information on each marker can be found following the table): Tumor Marker Afirma Thyroid FNA Analysis AFP (alpha-fetoprotein) AFP, lactate dehydrogenase (LDH), and beta-human chorionic gonadotropin (beta hcg) ALK Gene rearrangement B2M (beta-2 microglobulin) Bladder-tumor antigen stat test (BTA) Calcitonin CA (cancer antigen) 15-3, also known as CA 27.29 or Truquant RIA CA 19.9 CA125 Carcinoembryonic antigen (CEA) CgA (chromogranin A) CD- 117 (C-kit) (cluster of differentiation-117) Cyclin D1 Cancer Thyroid Cancer Primary hepatocellular cancer Germ cell tumors Refer to policy, Molecular Tumor Markers for Non-Small lung Cancer Multiple myeloma; Chronic lymphocytic leukemia; Some lymphomas (see below) Bladder cancer Thyroid medullary carcinoma Metastatic breast cancer Pancreatic cancer; Gallbladder cancer; Cholangiocarcinoma; Carcinoma of the ampulla of Vater Epithelial ovarian cancer; Endometrial cancer Breast Cancer: Colorectal cancer; Medullary thyroid cancer Neuroendocrine tumors (e.g., carcinoid tumors, neuroblastoma, and small cell lung cancer) Gastrointestinal stromal tumors Mantle cell lymphoma Tumor Makers for Cancer Apr 14 2

Tumor Marker EGFR (epidermal growth factor receptor) ER/PR (estrogen receptors and progesterone receptors) 5-HIAA (5-hydrocyindoleacetic acid) HE4 (human epididymis protein 4) HER2 (human epidermal growth factor receptor 2) ImmunoCyt/uCyte+ KRAS gene sequencing MPO (myeloperoxidase) Nuclear-Matrix Protein (NMP22) NSE (neuron-specific enolase) Placental alkaline phosphatase (PLAP) PSA (prostate-specific antigen) Thyroglobulin UroVysion Cancer Refer to policy, Molecular Tumor Markers for Non-Small lung Cancer Breast cancer Carcinoid tumors Ovarian cancer Refer to policy, Her2/neu Bladder cancer Refer to policy, Molecular Tumor Markers for Non-Small lung Cancer and K-RAS Mutation Analysis of Colon Cancer Acute myeloid leukemia Bladder cancer Small cell lung cancer Germ cell seminoma and non-seminoma germ cell tumors in unknown primary cancers Prostate cancer Differentiated thyroid cancer Bladder cancer Afirma Thyroid FNA The Afirma Thyroid FNA Analysis is intended for adults with thyroid nodules at least 1 centimeter in size, that are indeterminate and who are being evaluated for the possibility of a thyroid malignancy. AFP (alpha-fetoprotein) Hepatocellular Cancer AFP is not frequently elevated in early stage hepatocellular carcinoma (HCC) thus its utility as a screening biomarker is limited. AFP testing can be useful in conjunction with other test results to guide management of patients for whom a diagnosis of HCC is suspected. AFP is also useful in monitoring individuals with HCC. AFP, lactate dehydrogenase (LDH), and beta-human chorionic gonadotropin (beta HCG) Germ Cell Tumors Tumor Makers for Cancer Apr 14 3

AFP, LDH and beta-hcg are critical in diagnosing germ cell tumors (GCTs), determining prognosis, and assessing treatment outcome. They are useful for monitoring all stages of nonseminomas. They are useful in monitoring metastatic seminomas because elevated marker levels are early signs of relapse. B2M (beta-2 microglobulin) Multiple Myeloma The level of beta-2 microglobulin reflects the tumor mass and is considered a standard measure of the tumor burden in multiple myeloma. Chronic Lymphocytic Leukemia Elevated levels of serum beta-2microglobulin have been shown to be a strong independent prognostic indicator for treatment-free intervals, response to treatment, and overall survival, in individuals with chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) Lymphomas Beta-2 microglobulin may be useful prognostic indicator in anaplastic large cell lymphoma (ALCL) Beta-2 microglobulin is useful in the initial diagnostic work-up for Follicular lymphoma (FL), Diffuse Large B-Cell Lymphoma (DLBCL) Measurement of Beta-2 microglobulin may be useful in some circumstances in the initial work-up of mantle cell lymphoma, lymphoblastic lymphoma amnd Aids related B-Cell lymphoma. Bladder-tumor antigen stat test (BTA) Bladder Cancer Per the NCCN, urine molecular tests for urothelial tumor markers are now available. Most of these tests have a better sensitivity for detecting bladder cancer than urine cytology, but specificity is lower. However, it remains unclear whether these tests offer additional information that is useful for detection and management of non-muscle-invasive bladder tumors. NCCN considers this to be a 2B recommendation (i.e., Based on lower level of evidence, there is NCCN consensus that the intervention is appropriate) Calcitonin Medullary Thyroid Cancer Basal serum calcitonin and serum carcinoembryonic antigen (CEA) are generally accepted in the preoperative work-up for medullary thyroid cancer. Calcitonin is useful for post operative management and surveillance, to evaluate effectiveness of treatment and assess for recurrence of medullary thyroid cancer. CA 15-3; CA 27.29 Metastatic breast cancer The NCCN states that monitoring of patients symptoms and cancer burden during treatment of metastatic breast disease is important to determine whether the treatment is providing benefit and that the patient does not have toxicity from an ineffective therapy. Increasing tumor markers (CEA, CA 15-3 and CA 27.29) are findings that are concerns for progression of disease, but may also be seen in the setting of responding disease. An isolated increase in tumor markers should rarely be used to declare progression of disease. Changes in bone lesions are often difficult to assess on plain or cross-sectional radiology or on bone scan. For these reasons, patient symptoms and serum tumor markers may be more helpful in patients with bone-dominant metastatic disease. Tumor Makers for Cancer Apr 14 4

CA 19.9 Pancreatic Cancer The NCCN reports that the best validated and most clinically useful biomarker in pancreatic cancer is CA 19-9. CA 19-9 is commonly expressed and shed in pancreatic and hepatobiliary disease, and in many malignancies; thus it is not tumor specific. However, the degree of increase in CA 19-9 levels may be useful in differentiating pancreatic adenocarcinoma from inflammatory conditions of the pancreas. CA 19-9 is a good diagnostic marker in symptomatic individuals, but its low predictive value makes it a poor biomarker for screening. Preoperative CA 19-9 levels correlate with both AJCC staging and resectability and thus provide additional information for staging and determining resectability, along with information from imaging, laparoscopy and biopsy. CA 19-9 seems to have value as a prognostic marker. Low post operative levels or serial decrease following surgery have been found to correlate with survival for individuals undergoing resection for pancreatic cancer. Changes in CA 19-9 levels after chemotherapy in patients with advanced disease has been shown to be a reliable predictive marker for response to treatment. CA 19-9 may be undetectable in Lewis antigen-negative individuals. CA 19-9 may be falsely positive in cases of benign or malignant biliary obstruction and do not necessarily indicate cancer or advanced disease. NCCN recommends measurement of CA 19-9 levels prior to surgery (if bilirubin levels are normal), following surgery prior to administration of adjuvant therapy or for surveillance (category 2B, i.e., based on lower level evidence, there is consensus that intervention is appropriate) Biliary Tract Cancer CA 19-9 may be considered in initial workup of individuals with a suspicion of gallbladder cancer, although the markers are NOT specific for gallbladder cancer. CA 19-9 testing can be considered after biliary decompression. CA 19-9 may be considered in initial workup of individuals with a suspicion of cholangiocarcinoma, although the markers are NOT specific for cholangiocarcinoma. Ampullary Cancer Some ampullary cancers are associated with increased serum levels of CA 19-9 and/or carcinoembryonic antigen (CEA). Serial assay of these tumor markers may be useful for posttreatment follow-up. CA 125 Ovarian Cancer Per the NCCN, tumor markers (including CA-125, inhibin, AFP, and beta-hcg) can be measured if clinically indicated. Per the NCCN, CA 125 and other tumor markers may be done as clinically indicated prior to each cycle of chemotherapy. After completion of primary surgery and chemotherapy in individuals with all stages of ovarian cancer who have complete response, the recommendation is observation with follow-up. If the CA 125 level was initially elevated, the measurement of a CA 125 level or other tumor markers at each follow-up evaluation is recommended. The NCCN concurs with the Society of Gynecologic Oncology (SGO) opinion which states that individuals should discuss the pros and cons of CA 125 monitoring and that the use of CA 125 levels for surveillance is optional. The FDA has approved the use of HE4 and CA 125 for estimating the risk of ovarian cancer in women with a pelvic mass. Currently, the NCCN does not Tumor Makers for Cancer Apr 14 5

recommend the use of these biomarkers for determining the status of an undiagnosed pelvic mass. Endometrial Carcinoma Per the NCCN, in individuals with extrauterine disease, a serum CA 125 assay may be helpful in monitoring clinical response. However, serum CA 125 levels may be falsely increased in women who have peritoneal inflammation/infection or radiation injury, normal in women with isolated vaginal metastases and may not predict recurrence in the absence of other clinical findings. Both NCCN and SGO recommend that CA 125 and MRI/CT may be useful before surgery to assess if extrauterine disease is present. Hereditary Breast and Ovarian Cancer Syndrome (HBOC) For individuals with HBOC who have not elected salpingo-oophorectomy, the NCCN recommends considering concurrent transvaginal ultrasound (preferably day 1-10 of menstrual cycle in premenopausal women) and CA 125 (preferably after day 5 of menstrual cycle in premenopausal women) every 6 months starting at age 30y or 5-10 years before the earliest age of the first diagnosis of ovarian cancer in the family. Carcinoembryonic antigen (CEA) Breast Cancer Increasing tumor markers (CEA, CA 15-3 and CA 27.29) are findings that are concerns for progression of disease, but may also be seen in the setting of responding disease. An isolated increase in tumor markers should rarely be used to declare progression of disease. Changes in bone lesions are often difficult to assess on plain or cross-sectional radiology or on bone scan. For these reasons, patient symptoms and serum tumor markers may be more helpful in patients with bone-dominant metastatic disease. Colorectal Cancer Testing of CEA in the initial work-up is recommended for individuals who present with invasive colon cancer appropriate for resection. CEA determination should be included in the workup for individuals with metastatic synchronous adenocarcinoma. Colorectal Cancer Surveillance CEA testing is recommended at baseline and every 3-6 months for 2 years and then every 6 months for a total of 5 years, for patient with stage III disease and those with stage II disease if the clinician determines that the individual is a potential candidate for aggressive curative surgery. CEA testing is also recommended every 3-6 months for 2 years and then every 6 months for a total of 5 years, for individuals with stage IV disease with no NED after curative-intent surgery and subsequent adjuvant treatment. Surveillance of are similar to those recommendations for individuals with stage II/III disease, except that certain evaluations are performed more frequently. CEA testing is recommended every 3-6 months for the first 2 years. Routine CEA monitoring and routine CT scanning are not recommended beyond 5 years Medullary Thyroid Cancer Basal serum calcitonin and serum carcinoembryonic antigen (CEA) are generally accepted in the preoperative work-up for medullary thyroid cancer. A rapidly increasing CEA level, particularly in the setting of a stable calcitonin level may be important for predicting a worse prognosis. Tumor Makers for Cancer Apr 14 6

Measurement of CEA is useful for post operative management and surveillance, to evaluate effectiveness of treatment and assess for recurrence of medullary thyroid cancer. CgA (chromogranin A) Neuroendocrine tumors Chromogranin A may be used as a tumor marker; (NCCN category 3, i.e. based on any level of evidence, there is major NCCN disagreement that the intervention is appropriate) Although not diagnostic, elevated levels have been associated with recurrence. Analysis of a large prospective database showed that CgA levels elevated twice the normal limit or higher were associated with shorter survival times for individuals with metastatic neuroendocrine tumors. CgA levels can be elevated in other conditions (e.g., renal or hepatic insufficiency, hypertension, chronic gastritis) and are also commonly also elevated in the setting of concurrent proton pump inhibitors, thus caution should be used when considering initiating new therapy based on a rising CgA level in an asymptomatic individual with a tumor that appears stable. CD-117 (C-kit) (cluster of differentiation-117) Gastrointestinal Stromal Tumors Gastrointestinal stromal tumors (GISTs) that arise in adults are characterized by the near-universal expression of the CD117 antigen. The CD117 antigen is part of the KIT transmembrane receptor tyrosine kinase that is the product of the KIT (also denoted c-kit) protooncogene Cyclin D1 Non Hodgkins Lymphoma Per the NCCN, immunophenotyping/genetic testing is useful in the differential diagnosis of mature B-cell and NK/T-cell neoplasms in conjunction with clinical and morphologic correlation. In the differential diagnosis of small cell lymphomas [i.e., Chronic Lymphocytic Leukemia (CLL)/Small Lymphocytic Lymphoma (SLL), Mantle Cell Lymphoma (MCL), Hairy Cell Leukemia (HCL), Splenic Marginal Zone Lymphoma (MZL), extra-nodal MZL, nodal MZL, and Follicular Lymphoma] cyclin D1 is included in the panel for immunophenotyping. Distinguishing CLL/SLL from mantle cell lymphoma is essential and cyclin D1 expression is the most reliable marker for differentiating between CLL and MCL. In select cases, the use of cyclin D1 may be useful to differenciate PC-MZL from mantle cell lymphomas. Cyclin D1 is also include in the immunophenotyping panel for the diagnosis of medium-sized lymphomas [Burkitt lymphoma (BL), diffuse large B-cell lymphoma (DLBCL), blastoid variant of MCL.] Cyclin D1 positively confirms the diagnosis of blastoid MCL. ER/PR (estrogen receptors and progesterone receptors) Breast Cancer Per the NCCN, the work-up of individuals with invasive breast cancer should include determination of tumor estrogen/progesterone receptor (ER/PR) status and Her2 status. ER/PR tumor status is normally determined by immunohistochemistry (IHC) testing. Per NCCN, the revised AJCC cancer staging manual recommends the collection of prognostic factors, including tumor grade, estrogen receptor (ER) content, progesterone receptor (PR) content and human epidermal growth factor receptor Tumor Makers for Cancer Apr 14 7

2 (HER2) status, although these characteristics do not specifically influence assigned stage of disease. 5-HIAA (5-hydrocyindoleacetic acid) Carcinoid Tumor 5-hydrocyindoleascetic acid (5-HIAA), a metabolite of serotonin may also be considered as a biochemical marker in some cases, particularly in individuals with small-intestinal carcinoid tumors. Baseline levels of 5-HIAA may be considered to monitor subsequent progression of disease. HE4 (human epididymis protein 4) Per NCCN, although human epididymis protein 4 (HE4) and CA125 appear to be useful in detecting ovarian cancer, recent data showthat several markers (including CA125, HE4, etc) do not increase early enough to be useful in detecting early-stage ovarian cancer. The FDA has approved the use of HE4 and CA 125 for estimating the risk of ovarian cancer in women with a pelvic mass. Currently, the NCCN does not recommend the use of these biomarkers for determining the status of an undiagnosed pelvic mass. ImmunoCyt/uCyt+ Bladder cancer May be used for detecting primary bladder cancer in patients with signs/symptoms of bladder cancer or for detecting recurrent bladder cancer in patients with a history of bladder cancer, when used as an adjunct to cystoscopy and urinary cytology Per the NCCN, urine molecular tests for urothelial tumor markers are now available. Most of these tests have a better sensitivity for detecting bladder cancer than urine cytology, but specificity is lower. However, it remains unclear whether these tests offer additional information that is useful for detection and management of non-muscle-invasive bladder tumors. NCCN considers this to be a 2B recommendation (i.e., Based on lower level of evidence, there is NCCN consensus that the intervention is appropriate) MPO (myeloperoxidase) Acute Myeloid Leukemia Immunohistochemical staining for myeloperoxidase is the best method for determining which cells are committed to the myeloid lineage Nuclear-Matrix Protein (NMP22) Bladder Cancer Consideration may be given to the FDA approved urinary biomarker testing by fluorescence in situ hybridization or nuclear matrix protein 22 in the monitoring for recurrence. NSE (neuron-specific enolase) Small Cell Lung Cancer (SCLC) Neuroendocrine tumors account for approximately 20% of lung cancers; most (~15%) are small cell lung cancer. Most SCLCs stain positively for markers of neuroendocrine differentiation, including chromogranin A, neuron-specific enolase, neural cell adhesion molecule and synaptophysin. Placental alkaline phosphatase (PLAP) Tumor Makers for Cancer Apr 14 8

Occult Primary (Cancer of unknown Primary) Placental alkaline phosphatase (PLAP) is mainly found in seminomas but is also expressed in some nonseminoma germ cell tumors, and genitourinary, gastrointestinal, and pulmonary carcinomas. PSA (prostate-specific antigen) Prostate Cancer The decision to participate in an early detection program for prostate cancer is complex. Factors that should be considered include patient age, life expectancy, family history, race, and previous early detection test results. Initial suspicion of prostate cancer is based on abnormal digital rectal exam (DRE) or an elevated PSA level. Prostate cancers are characterized by clinical (TMN ) stage determined by DRE, Gleason score in the biopsy specimen, and serum PSA levels. NCCN guidelines incorporate a risk stratification scheme that uses a minimum of stage, grade and PSA to assign individuals to risk groups. These groups are used to select the appropriate options that should be considered for treatment and to predict the probability of biochemical failure after definitive local therapy. Biochemical progression-free survival can be reassessed post-operatively using age, serum PSA, and pathologic grade and stage. PSA levels are monitored in individuals choosing active surveillance and in individuals choosing active treatment. Many commercially available serum total PSA testing are currently available. They perform comparably, however, the levels are not interchangeable since they standardized against two different standards. An abnormal PSA result should be confirmed by retesting. Unbound or free PSA (fpsa) expressed as a ratio of total PSA has emerged as a clinically useful molecular form of PSA, with the potential to provide improvements in early detection, staging, and monitoring of prostate cancer. Studies have shown that the percentage of fpsa is significantly lower in men who have prostate cancer compared to men who have not. The US Food and Drug Administration (FDA) approved the use of percent-free PSA for the early detection of prostate cancer in men with PSA levels between 4-10 ng/ml. NCCN guidelines recommend the use of the percent-free PSA as an alternative in the management of patients with normal DREs and total PSA levels between 4-10ng/mL if there is a relative contraindication to biopsy. Physicians and patients electing to use percent-free PSA should be cautioned that this assay and the multi-institutional study performed to obtain its FDA approval were designed with the intention of avoiding unnecessary biopsies in men with a high likelihood of not having prostate cancer. Thyroglobulin Thyroid Cancer Thyroglobulin is most often measured in differentiated thyroid cancers (i.e., papillary, follicular, and Hurthle cell). Postoperative elevation of the thyroglobulin level above 10 nanograms per milliliter is suggestive of cancer recurrence UroVysion Bladder Cancer Per the NCCN, urine molecular tests for urothelial tumor markers are now available. Most of these tests have a better sensitivity for detecting bladder cancer than urine cytology, but specificity is lower. However, it remains unclear whether these tests offer additional information that is useful for detection and management of non-muscle-invasive bladder tumors. NCCN considers this to be Tumor Makers for Cancer Apr 14 9

The evaluation of thyroid nodules, which may represent benign lesions or malignant thyroid tumors, typically includes a cytopathologic examination of a biopsy specimen obtained by fine-needle aspiration (FNA). Generally, only nodules >1 cm should be evaluated, since they have a greater potential to be clinically significant cancers. Occasionally, there may be nodules <1 cm that require evaluation because of suspicious US findings, associated lymphadenopathy, a history of head and neck irradiation, or a history of thyroid cancer in one or more first-degree relatives. The NCCN notes that FNA is a very sensitive test, however, false negative results are sometimes obtained, therefore, a reassuring FNA should not override worrisome clinical findings. Cytologic examination of an FNA specimen is typically categorized as: carcinoma; follicular or Hurthle cell neoplasm; follicular lesion of undetermined significance; thyroid lymphoma; benign (i.e., nodular goiter, colloid goiter, hyperplastic /adenomatoid nodule, Hashimoto s thyroiditis) or insufficient biopsy (nondiagnostic) (NCI 2007). Thyroid nodules are subsequently classified based on cytology, with 70% to 75% of nodules being benign and approximately 5% being malignant. Approximately 20% to 25% of thyroid nodules are classified as indeterminate and represent a significant diagnostic challenge for physicians. Genetic or genomic markers have been investigated to aid in evaluating indeterminate thyroid nodules. There are two approaches to the molecular characterization of FNA aspirates that are commercially available in the United States: identification of particular molecular markers of malignancy, such as BRAF and RAS mutational status, and use of high density genomic data for molecular classification (an FNA-trained mrna classifier) The mrna classifier measures the Tumor Makers for Cancer Apr 14 14

activity level of 167 genes within the nodule (using the FNA aspirate). The Afirma Gene Expression Classifier measures the expression of 142 genes to reclassify ambiguous thyroid FNA samples as either benign or suspicious for cancer. The molecular portion of the test, which involves an analysis of RNA extracted from thyroid nodule aspirates, utilizes the GEC to classify indeterminate nodules as either benign or suspicious. An analysis of an additional 25 genes is included in order to help classify rare tumor subtypes. FNA samples for both cytopathology and the Gene Expression Classifier are performed at the same visit. Patient samples submitted for the Afirma Thyroid FNA Analysis are read by specialized cytopathologists at Thyroid Cytopathology Partners (TCP), an independent group based in Austin, Texas. Veracyte believes TCP to be the largest thyroid-only cytopathology practice in the country. According to Veracyte Inc., The Afirma Thyroid FNA Analysis provides a novel solution for improved thyroid nodule assessment. This advanced offering combines specialized cytopathology with the Gene Expression Classifier (GEC) for the management of patients with thyroid nodules. The GEC reclassifies FNAs (fine needle aspirates) with indeterminate cytopathology results as either benign or suspicious for cancer. By helping physicians pre-operatively identify benign nodules (negative predictive value greater than 94%) in approximately half of patients with indeterminate cytopathology, our solution may enable clinical and sonographic follow-up for these patients in lieu of diagnostic surgery. Studies show that the risk of malignancy of a benign GEC result (less than 6%) is similar to that of a benign cytopathology diagnosis. Per NCCN (2013), Molecular diagnostics to detect individual mutations [eg. BRAF, RET/PTC, RAS, Pax8-PPAR (peroxisome proliferator-activated receptors) gamma] or pattern recognition approaches using molecular classifiers may be useful in the evaluation of FNA samples that are indeterminate. The NCCN recommends molecular diagnostics for evaluating FNA results that are suspicious for Follicular or Hurthle cell neoplasms; or follicular lesion of undetermined significance. They note, Rather than proceeding to immediate surgical resection to obtain a definitive diagnosis in these categories, patients can be followed with observation if the applications of a specific molecular diagnostic test results in a predicted risk of malignancy that is comparable to the rate seen in cytologically benign thyroid FNA. It is important to note that the predictive value of molecular diagnostics may be significantly influenced by the pre-test probability of disease associated with the various FNA cytology categories. Furthermore, in the cytologically indeterminate groups, the risk of malignancy for FNA can vary widely between institutions. Because the published studies have focused primarily on adult patients with thyroid nodules, the diagnostic utility of molecular diagnostics in pediatric patients remains to be defined. Therefore, proper implementation of molecular diagnostics into clinical care requires an understanding of both the performance characteristics of the specific molecular test and its clinical meaning across a range if pre-test probabilities. The Afirma Thyroid FNA Analysis is not specifically mentioned by name in the guidelines. 2010 Guidelines from the American Association of Clinical Endocrinologists (AACE), Associazione Medici Endocrinologi (AME), and European Thyroid Association (ETA) state that molecular and immunohistochemical markers may improve the accuracy of cytologic diagnosis, but they do not have consistent predictive value for malignancy and their use is still expensive and restricted to specialized centers. On the basis of current limited evidence, routine use of molecular and immunohistochemical markers in clinical practice is not recommended and should be reserved for selected cases. The Afirma Thyroid FNA Analysis is not mentioned in the guidelines. Tumor Makers for Cancer Apr 14 15

The American Thyroid Association guidelines (updated 2009) reported that the use of molecular markers (e.g., BRAF, RAS, RET/PTC, Pax8-PPAR gamma, or galectin-3) may be considered for patients with indeterminate cytology on FNA to help guide management. (Recommendation rating: C I.e., The recommendation is based on expert opinion.) The guidelines do not mention genomic tests, such as the Afirma Thyroid FNA Analysis. Alexander et al (2014) analyzed all patients who had received Afirma GEC testing at five academic medical centers between 2010 and 2013. Nodule and patient characteristics, fine needle aspiration cytology, Afirma GEC results, and subsequent clinical or surgical follow-up were obtained for 339 patients. Results were analyzed for pooled test performance, impact on clinical care, and site-to-site variation. Three hundred thirty-nine patients underwent Afirma gene expression classifier (GEC) testing of cytologically indeterminate nodules [165 atypical or follicular lesion of undetermined significance (AUS/FLUS); 161 follicular neoplasm (FN); 13 suspicious for malignancy] and 174 of 339 (51%) indeterminate nodules were GEC benign, whereas 148 GEC were suspicious (44%). GEC results significantly altered care recommendations, as 4 of 175 GEC benign were recommended for surgery in comparison to 141 of 149 GEC suspicious (P<.01). Of 121 Cyto Indeterminate/GEC Suspicious nodules surgically removed, 53 (44%) were malignant. Variability in siteto-site GEC performance was confirmed, as the proportion of GEC benign varied up to 29% (P=.58), whereas the malignancy rate in nodules cytologically indeterminate/gec suspicious varied up to 47% (P=.11). Seventy-one of 174 GEC benign nodules had documented clinical follow-up for an average of 8.5 months, in which 1 of 71 nodules proved cancerous. The investigators concluded these multicenter, clinical experience data confirm originally published Afirma GEC test performance and demonstrate its substantial impact on clinical care recommendations. Although nonsignificant site-to-site variation exists, such differences should be anticipated by the practicing clinician. Follow-up of GEC benign nodules thus far confirm the clinical utility of this diagnostic test. Dedhia et al (2014) reported increasing utilization of genetic expression profiling (GEP) for thyroid nodules with indeterminate FNA results will potentially decrease the number of patients requiring diagnostic thyroidectomy.a retrospective review of thyroidectomy procedures performed over 1 year at the University of Michigan in the endocrine surgery division evaluated the indications for thyroidectomy, FNA Bethesda classification, and final surgical pathology to determine how application of GEP on indeterminate FNA results would affect decision for surgery and subsequent thyroidectomy volume. During the study period, 358 thyroidectomies were performed. The indication for procedure included: FNA findings, n = 122; symptomatic multinodular goiter, n = 85; nodule >4 cm, n = 30; Graves', n = 26; other, n = 95. FNA was performed in 231 patients. Bethesda classification included: benign, n = 69; malignant, n = 55; follicular lesion of undetermined significance, n = 59; follicular neoplasm, n = 20; suspicious for malignancy, n = 16; nondiagnostic, n = 12. If standard GEP was performed for all indeterminate FNA results, it would have influenced the decision for surgery in 68 (19 %) patients. Assuming 38 % of indeterminate FNA specimens will have benign results on genetic profiling, 27 patients would not have undergone thyroidectomy, translating into a 7.2 % decrease in overall thyroidectomy volume over a year. Reviewers concluded that in an academic endocrine surgery program, the most common indication for thyroidectomy is an FNA result; however, standard application of GEP for all indeterminate thyroid FNAs would result in a minimal reduction in overall thyroidectomy volume. Harrell and Bimston (2013) analyzed the performance of the GEC over 27 months in a community hospital-based thyroid surgery practice. Authors began using GEC and Thyroid Cytopathology Partners (TCP) exclusively for thyroid FNA analysis in 1/2011, Tumor Makers for Cancer Apr 14 16

shortly after the Afirma GEC first became commercially available. They focused on patients with indeterminate FNA results and the outcomes of GEC analysis, with particular attention to the calculation of the negative predictive value of the Afirma test. They performed 645 FNA's in 519 patients over 27 months. 58 of the FNA's (9%) were read as indeterminate, with 36 of these classified as suspicious by GEC (62%), 20 characterized as GEC benign (34%) and 2 determined to be inadequate due to low mrna content. Of the 36 suspicious GEC patients, 30 underwent thyroidectomy and 21 of the 30 had malignant final pathology. Of the 20 benign GEC patients, 5 underwent thyroid surgery and 2 were discovered to have malignancies. Negative predictive value for the Afirma GEC in their practice environment was 89.6%. The authors concluded in a practice with a high incidence of thyroid cancer in patients with indeterminate FNA's (33% for their practice), the negative predictive value of the Afirma GEC test may not be as robust as suggested in the literature to date. Gomberawalla and Elaraj (2014) reported multiple genetic mutations have been found to be associated with thyroid cancer, and molecular testing of thyroid nodule FNA specimens has been proposed as an adjunct to the cytologic diagnosis. The reviewers examined how molecular testing of FNAs could be used to guide surgical decision-making. B-type RAF kinase mutations in papillary thyroid cancer have been found to be associated with extrathyroidal extension, lymph node metastases, and advanced stage in two meta-analyses that are based largely on retrospective data. Testing for a panel of gene mutations has been found to have high specificity and positive predictive value, whereas microarray testing using a commercially available gene-expression classifier has been found to have high sensitivity and negative predictive value for the diagnosis of malignancy in cytologically indeterminate FNAs. Although there is no consensus regarding the use of such tests, they have already started to change clinical practice. Reviewers concluded molecular testing of FNA specimens may help to avoid diagnostic thyroidectomy or may help in deciding the extent of surgery in a patient with an indeterminate FNA biopsy. The use of these tests is currently undergoing review by a task force within the American Thyroid Association. The evidence supporting the validity and utility of the Afirma Thyroid FNA Analysis is somewhat limited, although it consistently supports the assertion that the assay may be useful as a rule out test, used to help exclude malignancy in thyroid nodules with indeterminate FNA cytology. Given its relatively high NPV (i.e., approximately 90% to 96%), the likelihood of a thyroid malignancy may be decreased significantly in many patients with indeterminate FNA biopsies. In addition, evidence supporting the clinical utility indicates that GEC results may influence medical management decisions in patients with indeterminate thyroid nodules and can lead to a significant decrease in diagnostic thyroid surgeries Scientific Rationale Update February 2014 Molecular Intelligence (MI) is a group of molecular biomarker tests provided by Caris Life Sciences, based upon a previous test, Target Now Molecular Profiling. Molecular Intelligence differs from Target Now in its methodology, which incorporates nextgeneration sequencing (NGS), and in the biomarkers analyzed. The MI profile includes immunohistochemistry (IHC), fluorescence/chromogenic in situ hybridization (FISH/CISH), next-generation sequencing (NGS), and quantitative polymerase chain reaction (qpcr) methodologies performed on formalin-fixed, paraffin-embedded (FFPE) tissues or biopsies preserved in neutral buffered formalin. Molecular Intelligence is proposed to provide information based upon literature review that associates a tumor s biomarker status with therapeutic agents that may have potential or lack of potential clinical benefit. It is proposed to identify open clinical trials relevant to particular biomarkers, with information provided in the form of a MI Tumor Makers for Cancer Apr 14 17

Profile Report. The MI Profile is for use in solid tumors, intended for therapeutic decision support and qualification for clinical trials in the treatment of aggressive, rare, or refractory cancers. Although Caris Molecular Intelligence is available for all solid tumors, including cancers of unknown primary, it is especially helpful when treating rare tumors or cancers with undefined standard of care, (e.g. sarcoma or glioma), aggressive cancers with few standard treatment options, (e.g. melanoma, pancreatic cancer), and difficult-to-treat cancers, such as certain metastatic and refractory diseases, e.g.(ovarian or triple-negative breast cancer). Although there are studies on molecular biomarkers, there are currently no Clinical Trials and a paucity of published peer reviewed data specifically on the Molecular Intelligence assay for cancer, therefore, it is considered investigational at this time. There is no information in NCCN Guidelines on (2014) Colon Cancer, (2014) Occult Primary Cancer, (2013) Soft Tissue Sarcoma, (2014) Melanoma, (2014) Pancreatic Cancer, (2013) Ovarian Cancer. or (2014) Breast Cancer, that specifically addresses the Molecular Intelligence assay. Scientific Rationale Initial Tumor markers are indicators of cellular, biochemical, molecular, or genetic alterations whereby neoplasia can be recognized. Tumor markers fall into three broad categories proteins, genetic mutations, and epigenetic changes (e.g., differential promoter-region methylation). The utility of tumor markers is adjunctive to medical and surgical management of malignancies, serving to help detect recurrences as well as predict prognosis. The clinical value of any given tumor marker will depend on its specificity and sensitivity as well as its intended clinical use. Serum tumor markers are currently used for screening, diagnosing, and predicting prognosis and treatment response. Use of tests for screening of disease, even those with high sensitivity and specificity, should be confined as much as possible to populations at risk for the disease. Bladder Cancer According to the National Comprehensive Cancer Network (NCCN), bladder cancer is the fourth most common cancer, occurring three times more often in men than women in the U.S. Bladder cancer is rarely diagnosed in individuals younger than 40 years. Bladder cancer is divided into three categories: non-muscle-invasive tumors, muscle invasive lesions and metastatic lesions. Prognosis, management and therapeutic aims differ among the categories. The diagnosis of bladder cancer commonly is suggested by the presence of hematuria, which may be either gross or microscopic. However, hematuria is frequently seen in a wide range of benign conditions. The diagnosis of bladder cancer ultimately requires a histologic diagnosis, which usually comes from a biopsy that is obtained at cystoscopy. Cytology may provide strong evidence for the presence of malignancy, but it has a low sensitivity and occasional false positives are reported. Urine biomarkers have potential applications in individuals in whom bladder cancer is suspected based upon the presence of hematuria, symptoms, or in whom there is an unusually high risk of tumor. Urine biomarkers may also have a role in detecting recurrences in patients who have been treated for non-muscle-invasive disease. Although cystoscopy is the gold standard for surveillance in patients with a history of bladder cancer, it does not detect all recurrences nor does it visualize the upper urinary tract. Performing a biomarker test in addition to cystoscopy may minimize the risk of missing a high grade tumor. Tumor Makers for Cancer Apr 14 18

A number of urine biomarkers and techniques are being evaluated. Many of these are based upon immunologic detection of soluble molecules in the urine [e.g., Bladder tumor antigen (BTA-STAT, Nuclear matrix protein 22 (NMP 22)]. Other techniques analyze exfoliated cells that are isolated from urine or bladder washings by centrifugation (e.g., UroVysion, ImmunoCyt). Per 2013 NCCN guidelines on Bladder cancer, Management of bladder cancer is based on pathologic findings of biopsy specimen, with attention to histology, grade and depth of lesion. These factors are used to estimate the probability of recurrence and progression to a more advanced stage. Consideration may be given to the FDA approved urinary biomarker testing by fluorescence in situ hybridization or nuclear matrix protein 22 in the monitoring for recurrence. NCCN guidelines on bladder cancer also state that urine molecular tests for urothelial tumor markers are now available. Most of these tests have a better sensitivity for detecting bladder cancer than urine cytology, but specificity is lower. However, it remains unclear whether these tests offer additional information that is useful for detection and management of non-muscle-invasive bladder tumors. NCCN considers this to be a 2B recommendation (i.e., Based on lower level of evidence, there is NCCN consensus that the intervention is appropriate). Miyake et al (2012) investigated the influence of hematuria on the performance of the bladder tumor antigen (BTA) tests in a clinical cohort and in an experimental model. Urine samples from a cohort of 126 subjects (64 with BCa and 62 controls) were analyzed by ELISA for hemoglobin and BTA. The experimental model involved the spiking of urine with blood from the same subject, and hemoglobin, red blood cell count, and BTA levels (BTA stat and BTA-TRAK). BTA-TRAK analyses were also performed on serum samples obtained from 40 subjects (20 with confirmed with BCa). In the 126 subject cohort, correlation between hemoglobin and BTA was 0.732. Of the 64 BCa samples, 72 % had a positive BTA assay, but 47 % of controls were also positive. The sensitivity and specificity of BTA to detect BCa was 72 and 53 %, respectively. Hematuria, measured by urinary hemoglobin, was a better indicator of BCa with 75 % sensitivity and 90 % specificity. Spiking of BTA-negative urine samples with as little as 1 μl/10 ml was enough to produce a positive BTA test. High levels of BTA were found equally in the serum of subjects with or without BCa (mean BTA levels 355,159 vs. 332,329 U/ml, respectively). Investigators concluded rather than detecting a bladder tumor antigen, urinary BTA assays may be measuring serum cfh introduced by bleeding, a common presenting factor in BCa subjects. The presence of hematuria in subjects without malignant disease can result in falsepositive BTA assays. Lüdecke et al (2012) tested the suitability of three point of care (POC) test systems, UBC rapid, NMP22 BladderChek and BTA stat, available on the market, with respect to interference due to blood contamination in urine samples. Urine samples were obtained from voluntary asymptomatic individuals without a history of bladder cancer. A specimen negative in all test systems was selected for further study. This sample was treated with fresh heparinized blood in a 1:10 ratio and then titrated in a dilution series. All the urine samples and their consecutive test results were photographed and a urinalysis was performed on each sample. In none of the samples of the dilution series did UBC rapid or NMP22 BladderChek show a falsepositive result due to blood contamination. In contrast, with the BTA stat testing system, false-positive results were obtained from all samples with macrohaematuria and with densities up to 150 erythrocytes/μl, indicating a suspected tumor, whereas the sample was actually proven to be tumor free. Investigators concluded for the primary diagnosis of bladder carcinoma, neither the UBC rapid nor the NMP22 BladderChek POC test systems are sensitive to the presence of blood in the urine, whereas BTA stat consistently yields false-positive results due to cross-reactivity to Tumor Makers for Cancer Apr 14 19

macrohaematuria and microhaematuria up to a density of 150 erythrocytes/μl, thus this system should not be employed for this examination. Todenhöfer et al (2013) investigated whether combinations of 4 of the most broadly available tests [cytology, FISH, ucyt+, and nuclear matrix protein 22 (NMP22- ELISA)] may improve their diagnostic performance. The study was comprised of 808 patients who were suspected of having urothelial carcinoma (UC). All patients underwent urethrocystoscopy and upper urinary tract imaging and, in the case of positive findings, transurethral resection/biopsy. FISH, ucyt+, cytology, and NMP22- ELISA were performed in all patients. UC was diagnosed in 115 patients (14.2%). Cytology and FISH were found to be the single tests with the best overall performance (area under the curve [AUC], 0.78/0.79). Combinations of 2, 3, and 4 markers were found to increase the AUC to various extents compared with the use of single markers. Combining cytology and FISH improved the sensitivity and performance (AUC, 0.83) compared with the single tests and identified 12 tumors that were not detected by cytology alone. The percentage of WHO grade 3/carcinoma in situ tumors not detected by cytology was reduced by 62.5% when FISH was performed in cytology-negative patients. The addition of ucyt+ as a third test further improved performance (AUC, 0.86), whereas the addition of NMP22- ELISA was not found to have any additional influence on the performance of the test combination. Investigators concluded the results of the current study support the combined use of urine markers and may form the basis of further studies investigating whether risk stratification based on urine marker combinations may individualize diagnostic algorithms and the surveillance of patients suspected of having UC. Hatzichristodoulou et al (2012) compared nuclear matrix protein 22 expression by BladderChek and ELISA, as urine-based assays for bladder cancer (BC) detection. Urine samples of 100 BC patients and 100 controls were analyzed. Comparative statistical evaluations were based on sensitivity and specificity. Seventy-one patients had primary and 29 recurrent BC. The sensitivity of BladderChek was significantly higher compared to ELISA in the overall cancer cohort and in patients with primary BC (p<0.0001 and p=0.0001, respectively). Both tests demonstrated significant correlation of sensitivities and tumor stage/grade for the overall cancer cohort and for patients with primary BC. Both tests had specificity values of 100% in healthy individuals. Specificity was 93% for BladderChek and 99% for ELISA in patients with benign diseases (p=0.048). Investigators concluded BladderChek may be clinically more useful for BC detection. Due to high specificity, BladderChek could be used for high-risk screening. However, due to its low sensitivity, BladderChek cannot replace but only complement cystoscopy for BC detection. Schlake et al (2012) compared the performance of NMP-22, urinary cytology and office cystoscopy when utilized in a urology practice for 1 year. A total of 391 consecutive office cystoscopy procedures performed over 1 year were included in the study. NMP-22 and cytology were performed on the urine specimens of patients presenting for cystoscopy. Tumor resection/bladder biopsy was performed when cystoscopy, NMP-22 or urinary cytology were abnormal. Cystoscopy, NMP-22, and urinary cytology data were available in 351 encounters and 69 tumor resections were performed. Urothelial carcinoma bladder (UCB) was identified in 37 bladder specimens. NMP-22, urinary cytology and cystoscopy demonstrated sensitivity and specificity of (51%/96%), (35%/97%), and (92%/88%), respectively. Investigators concluded the study demonstrates cystoscopy was the most sensitive test in the diagnosis of UCB. NMP-22 had a higher sensitivity than urinary cytology and similar specificity to cytology. The authors concluded additional urinary marker testing has a limited role in the management of bladder cancer in the office setting. When adjunct Tumor Makers for Cancer Apr 14 20
