요약

Early-stage NSCLC에서 perioperative pembrolizumab 후 tumor microenvironment와 peripheral circulation의 immune profiling을 통해 MPR 관련 biomarker를 탐색한 연구다.

핵심 포인트

방법

NCT02818920 phase 2 neoadjuvant pembrolizumab trial의 biospecimens를 이용해 baseline 및 post-treatment PBMC, resected tumor immune cells를 profiling했다.

주요 결과

Baseline PBMC와 tumor microenvironment에서 MPR과 관련된 immune cell subset 및 marker distribution differences가 확인되었다.

해석

Pembrolizumab monotherapy neoadjuvant setting에서 response prediction은 cell frequency만이 아니라 marker distribution과 immune architecture를 함께 봐야 한다.
