Objective: Approximately 30% of non-small cell lung cancers will recur after surgery, highlighting a need for additional perioperative therapies. Several recent clinical trials demonstrated a reduction in non-small cell lung cancer recurrence with the use of neoadjuvant chemoimmunotherapy. Recognizing that trial results may not always be replicated in the general population, our objective was to evaluate perioperative outcomes of immunotherapy in the real-world setting.

Methods: Adult patients diagnosed with clinical stage I to III non-small cell lung cancer in the National Cancer Database between 2018 and 2022 were included. Perioperative outcomes were evaluated in the following groups: neoadjuvant chemoimmunotherapy, neoadjuvant chemotherapy, or neoadjuvant chemoradiotherapy.

Results: Overall, 3956 patients were identified, including 1051 treated with neoadjuvant chemoimmunotherapy (33.2%), 1590 treated with chemotherapy (40.1%), and 1315 treated with neoadjuvant chemoradiotherapy (26.5%). The pneumonectomy rate after induction chemoimmunotherapy was 6.2%, which was lower than after chemotherapy (10.0%, P = .001) but similar to after chemoradiotherapy (7.9%, P = .11). Postoperative 90-day mortality among patients receiving chemoimmunotherapy was less than 1.0%, which was lower than both chemotherapy (2.0%, P < .001) and chemoradiotherapy (3.5%, P < .001). Nodal downstaging was seen in 43.9% of patients receiving chemoimmunotherapy. The pathologic complete response rate was 30.2%, which was higher than chemotherapy (9.1%, P < .001) but comparable to chemoradiotherapy (26.8%, P = .13). Results from adjusted logistic regressions were consistent with findings of unadjusted analyses.

Conclusions: Real-world outcomes suggest that the reassuring safety and impressive downstaging effect of neoadjuvant chemoimmunotherapy seen in clinical trials can be reproduced in the general population with non-small cell lung cancer. Further study to understand the impact of perioperative chemoimmunotherapy in the real-world setting is justified.
