Abstract

Background and Objectives: Biologic therapy is changing the landscape of lung cancer treatment. The objectives of this study were to compare overall survival (OS) between patients with non–small cell lung cancer (NSCLC) undergoing neoadjuvant and adjuvant biologic therapy in combination with surgery and to evaluate the impact of chemotherapy on survival after combination biologic therapy and surgery. Methods: The National Cancer Database was queried for cases of NSCLC from 2004 to 2016. Patient treatment was categorized into neoadjuvant and adjuvant biologic therapy in combination with surgery. Kaplan-Meier curves were generated to compare OS between treatment groups and between those who did and did not also undergo chemotherapy. Cox regression was used to identify factors predictive of OS. Results: Six hundred seventy-three patients underwent both biologic therapy and surgery. The unadjusted overall 5-year OS was longer for patients undergoing neoadjuvant biologic therapy than for those undergoing adjuvant biologic therapy (P =.006), with OS being 56.2% and 33.0%, respectively. When comparing OS between those who did and did not undergo additional chemotherapy, no difference was observed. Conclusions: Neoadjuvant biologic therapy was associated with longer OS than adjuvant biologic therapy. Chemotherapy did not have an effect on OS when combined with biologic therapy and surgery.
