Excerpt:
6/29 (21%; 95% CI: 0.08-0.40) achieved ypCR with TRS 0 in resected patients. 26/29 (90%; 95% CI: 0.73-0.98) had ypRR with TRS ≤2. Twenty-six patients finished adjuvant therapy with a median 36.3-month follow-up...Preoperative ICI + chemotherapy enhanced immune responses significantly with increasing expression of PD-L1 (CPS ≥10, p = 0.0078) and CD8 (>5%, p = 0.0059)...The perioperative pembrolizumab and mFOLFOX combination in resectable esophageal/gastric/GEJ adenocarcinoma is very effective with 90% ypRR, 21% ypCR, and impressive long-time survival benefits.
