AGENDA Revised (8th) Edition of TNM Staging System for Lung Cancer Surgical Approaches in Localized Lung Cancer Radiation for Localized Lung Cancer
PRINCIPLES OF SURGICAL THERAPY Resection is the preferred local treatment RESECTION Anatomic pulmonary resectionis preferred for the majority of patients Sublobar resection: segmentectomy and wedge resection with: Margins > 2 cm or > the nodule size Appropriate N1 &N2 sampling Sublobar / wedge resection is appropriatein: Poor pulmonary reserve or major comorbidity that contraindicates lobectomy. Peripheral nodule < 2 cm with at least one of the following: Pure AIS histology. > 50% GGO in CT. Long doubling time (> 400 days) in radiologic surveillance.
PRINCIPLES OF RADIATION THERAPY Early-stage NSCLC (Stage I) SBRT is recommended for inoperable patients or those who refuse surgery. SBRT is appropriate for high surgical risk patients (do not tolerate lobectomy). SBRT comparable disease control rate and OS to lobectomy in operable disease. TheLancet, May 14, 2015: similar efficacy, lesstoxicity withsbrt
Surgical Approaches in Localized Lung Cancer ORAL35.02 -Wedge Resection vs Segmentectomy for Patients with T1A N0 Non-Small Cell Lung Cancer ORAL35.03 -Salvage Surgery for Local Failures after Stereotactic Ablative Radiotherapy for Lung Malignancies ORAL35.05 -The Role of Surgical Mediastinal Resection in CT Screen-Detected Lung Cancer Patients ORAL35.07 -The Feasibility and Safety of Complete VATS for NSCLC Under Non-Intubated Intravenous Anesthesia in Comparison with Intubated Anesthesia
ORAL 35.02 What is better?
Wedge resection might have lower perioperative mortality than lobectomy or segmentectomy. Retrospective database analysis Objective: To assess outcomes of patients who underwent wedge resection or segmentectomyfor stage T1aN0 NSCLC No differences in pts characteristics (1230 each arm)
CONCLUSIONS SegmentectomyforT1aN0M0 NSCLC patienthas betteros evenin < 1 cm tumors and forpatientswithno comorbidities Segmentectomyshouldbe thepreferred sublobar resectionfor ct1an0 NSCLC
ORAL 35.03
1 out of 4 lung tumors that are medically operable prefers SBRT. Carefully follow-up and early detection of local recurrence is critical. Limited information of salvage surgery after SBRT. MATERIAL AND METHODS 9 ptshad recurrence of early NSCLC 8 ptshad recurrence of lung mets, 4 ptstreated for lung mets underwent 2 separate resections for local recurrence
16/21 hadno furtherprogression OS aftersurgery: Median: 38 m 1 year: 100% 2 years: 80% CONCLUSIONS: Salvagesurgery for isolatedlocal recurrenceafterlung SBRT is feasiblewithoutmajorcomplications
ORAL35.05
Therapeutic value of MLNR continues to be a source of debate ACOSOG Z0030 trial: OS similar in early cancer with regard to complete LN resection vs LN sampling. Hypothesis: is MLNR necessary in small tumors detected by screening? I-ELCAP DATABASE RESECTED NSCLC More lobectomy and central tumors in the MLNR group
CONCLUSIONS For patients with small screen-diagnosed NSCLC it seems reasonable not to perform lymph node sampling, particularly in subsolidnodules. Future prospective studies are needed
ORAL 35.07
INTRODUCTION VATS usually performed under general anesthesiawith single-lung ventilation (GATI) Retrospective analysis of patients who received VATS radical resection of lung cancer under IV anesthesiawith spontaneous brathing (IASB) over 3 years
RESULTS Significantly lower postop stay in the intervention group. CONCLUSION: VATS under non-intubated anesthesia is safe and feasible and might have advantages in terms of post-op rehabilitation

Observation for Early-Stage NSCLC in Elderly Patients ORAL19.01 -The SPACE Study: A Randomized Phase II Trial Comparing SBRT and 3DCRT in Stage I NSCLC Patients; Final Analysis including HRQL ORAL19.03 -NRG Oncology/RTOG 0813 Trial of Stereotactic Body Radiotherapy (SBRT) for Central Tumors -Adverse Events
MINI 18.01 Do we have to treat inoperable, elderly patients?
No random studies of observation vs SBRT in elderly, medically inoperable patients. Retrospective study. National Cancer Data Base NSCLC treated with SBRT or no treatment, > 70 years, T1-3N0M0, 2003-2006. Primary endpoint: OS SBRT: 258 pts No treatment: 2.889 pts Med age: 79 y All patients better survival with SBRT
CONCLUSION: SBRT reducesa36%therelativerisk of deathin elderlypatientsvsno treatment.
ORAL 19.01
Jan 2007-Jul 2011 N: 102 ( 49 SBRT, 53 DCRT) Follow up 37 months
CONCLUSIONS: SBRT has numerically less toxicity, better QoL, improved DCR.
ORAL19.03
INTRODUCTION SBRT is used for inoperablepatients with peripheral tumors. High toxicity observed for central tumors. Phase I/II trial Primary objective: To determine MTD of SBRT for centrally-located NSCLC and the tumor control rate at the MTD. METHODS: N: 120 pts HerearereportedAEsobservedin thetrial DLT andmtd submittedto ASTRO 2015
4 G5 toxicity: hemoptysisoccurringat 13 m post SBRT (range 5.5-14m) AlthoughSBRT waswelltolerated, 4/100 ptshadfatal hemoptysisattributableto SBRT. Verypreliminarydata
TAKE HOME MESSAGES Revised (8th) Editionof TNM More relevance to tumor size & reclassification of some T descriptors Acknowledgement of relevance of quantification of nodal disease Three metastatic groups More stages for better prognostic stratification Operable patients: For patients with small screen-diagnosed NSCLC it is reasonable not to perform lymph node sampling, particularly in subsolidnodules. VATS under non-intubated anesthesia is safe and feasible and might have advantages in terms of post-op rehabilitation
TAKE HOME MESSAGES Operable patients: Patientsnotsuitable for lobectomy: Segmentectomy should be thepreferred sublobar resectionforct1an0 NSCLC. Salvagesurgeryforlocal recurrenceafterlungsbrt is feasiblewithoutmajorcomplications. Inoperable patients: SBRT in elderly, medicallyinoperable patientsseemsbetter thanobservationin ct1-3n0m0 tumors. In NSCLC T1-2 < 6cm SBRT presents numericallyless toxicity, betterqol, improved DCR (Phase II). Notreadyfor SBRT in central NSCLC tumors.
