Complete response induced by anti–PD‐1‐based immunotherapy with toripalimab in a patient with locally advanced lung adenocarcinoma who failed rapidly after concurrent chemoradiotherapy: A case report

Abstract

What is known and objective Several immune checkpoint inhibitors (ICIs) are now available for treatment of non‐small cell lung cancer (NSCLC). However, not all patients benefit from ICI therapy, and the choice of ICIs is limited. Case summary A 54‐year‐old man with locally advanced NSCLC achieved partial response after definitive chemoradiotherapy. When he opted for consolidation therapy, metastatic lesions were found. Surprisingly, after immunotherapy with toripalimab, he quickly achieved complete response. What is new and conclusion As a PD‐1 inhibitor, toripalimab may be an effective option for subsequent therapy of patients with locally advanced NSCLC after concurrent chemoradiotherapy.
