A systematic review and meta-analysis. PG - 2794-2807 LID - 10.1097/JS9.0000000000000496 [doi] AB - OBJECTIVE: Overall survival is the gold-standard outcome measure for phase 3 trials, but the need for a long follow-up period can delay the translation of potentially effective treatment to clinical practice. The validity of major pathological response (MPR) as a surrogate of survival for non small cell lung cancer (NSCLC) after neoadjuvant immunotherapy remains unclear. METHODS: Eligibility was resectable stage I-III NSCLC and delivery of PD-1/PD-L1/CTLA-4 inhibitors prior to resection; other forms/modalities of neoadjuvant and/or adjuvant therapies were allowed. Statistics utilized the Mantel-Haenszel fixed-effect or random-effect model depending on the heterogeneity ( I2 ). RESULTS: Fifty-three trials (seven randomized, 29 prospective nonrandomized, 17 retrospective) were identified. The pooled rate of MPR was 53.8%. Compared to neoadjuvant chemotherapy, neoadjuvant chemo-immunotherapy achieved higher MPR (OR 6.19, 4.39-8.74, P <0.00001). MPR was associated with improved disease-free survival/progression-free survival/event-free survival (HR 0.28, 0.10-0.79, P =0.02) and overall survival (HR 0.80, 0.72-0.88, P <0.0001). Patients with stage III (vs I/II) and PD-L1 >/=1% (vs <1%) more likely achieved MPR (OR 1.66,1.02-2.70, P =0.04; OR 2.21,1.28-3.82, P =0.004). CONCLUSIONS: The findings of this meta-analysis suggest that neoadjuvant chemo-immunotherapy achieved higher MPR in NSCLC patients, and increased MPR might be associated with survival benefits treated with neoadjuvant immunotherapy. It appears that the MPR may serve as a surrogate endpoint of survival to evaluate neoadjuvant immunotherapy. CI - Copyright (c) 2023 The Author(s). Published by Wolters Kluwer Health, Inc.
