Review and perspective on adjuvant and neoadjuvant immunotherapies in NSCLC.

Postoperative patients have risk recurring, even for completed resected early stage non-small-cell lung cancer (NSCLC). To control the recurrence rate, neoadjuvant and adjuvant therapies have been applied widely in clinical practice; however, neoadjuvant and adjuvant immunotherapy clinical trials on NSCLC are still being explored. In this review, we summarized the research progress and outline the issues need to be solved on adjuvant and neoadjuvant immunotherapies in NSCLC.
