Perioperative Outcomes and Survival After Preoperative Immunotherapy for Non-Small Cell Lung Cancer.
BACKGROUND: Although preoperative immunotherapy is increasingly utilized for non-small cell lung cancer, there remains a paucity of robust clinical data on its safety and long-term survival. Our objective was to evaluate the perioperative outcomes and survival associated with immunotherapy followed by surgery for patients with non-small cell lung cancer. METHODS: Outcomes of patients with non-small cell lung cancer who underwent lung resection after preoperative chemotherapy with or without radiation or immunotherapy (with or without chemotherapy or chemoradiation) in the National Cancer Database (2010 to 2017) were evaluated using Kaplan-Meier analysis, multivariable logistic regression, multivariable Cox proportional hazards analysis, and propensity score-matched analysis. RESULTS: From 2010 to 2017, 236 patients (2.2%) received immunotherapy and 10 715 patients received preoperative chemotherapy followed by surgery. There were no significant differences between the immunotherapy and preoperative chemotherapy groups with regard to margin positivity (8.5% [n = 20] vs 7.5% [n = 715], P = .98), 30-day readmission (4.2% [n = 10] vs 4.1% [n = 440], P = .87), and 30-day mortality (0.4% [n = 1] vs 2.4% [n = 253], P = .25). The immunotherapy and preoperative chemotherapy groups had similar overall survival (5-year survival 63% [95% confidence interval, 50% to 74%] vs 51% [95% confidence interval, 50% to 52%], log rank P = .06; multivariable adjusted hazard ratio 0.98; 95% confidence interval, 0.67 to 1.41; P = .90). A propensity score matched analysis of 344 patients, well matched by preoperative characteristics, showed no significant differences in short-term outcomes and overall survival (log rank P = 1.00) between the two groups. CONCLUSIONS: In this national analysis, preoperative immunotherapy followed by surgery for non-small cell lung cancer was found to be safe and feasible with similar short-term outcomes and overall survival when compared with preoperative chemotherapy followed by surgery.
