Abstract
•
Resectable NSCLC has a high recurrence rate of 30-55%. Neoadjuvant, adjuvant, or perioperative combination of ICIs and CTX improved survival outcomes and response rates compared to CTX alone. Our meta-analysis of 11 RCTs suggests that neoadjuvant or perioperative treatment resulted in more favorable OS, EFS, and pathological response rates, supporting the use of these treatment regimens in this patient population. Meanwhile, adjuvant ICI significantly improved DFS with a trend towards improvement in OS.
•
Positive PD-L1 status, non-squamous histology, and stage III achieved a more profound EFS advantage. A longer, perioperative regimen might be required to improve survival outcomes in subgroups that obtained less advantage from ICI, such as squamous histology. Other clinical factors, such as age, sex, race, and geographical location, did not modify the benefit obtained from ICI, exhibiting the generalizability of ICI in different demographics.
•
Head-to-head studies to compare neoadjuvant versus perioperative ICI and the duration of adjuvant ICI should be further investigated to determine the optimal sequence and duration of ICI in patients with resectable NSCLC.
期刊介绍:
Clinical Lung Cancer is a peer-reviewed bimonthly journal that publishes original articles describing various aspects of clinical and translational research of lung cancer. Clinical Lung Cancer is devoted to articles on detection, diagnosis, prevention, and treatment of lung cancer. The main emphasis is on recent scientific developments in all areas related to lung cancer. Specific areas of interest include clinical research and mechanistic approaches; drug sensitivity and resistance; gene and antisense therapy; pathology, markers, and prognostic indicators; chemoprevention strategies; multimodality therapy; and integration of various approaches.
