Successes and failures of immunotherapy for gastric cancer

Abstract

Many exploratory clinical studies have been conducted on immune checkpoint inhibitors (ICIs) as new therapeutic approaches for the first-line treatment of patients with advanced gastric cancer. Despite varying interpretations of the successes and failures of this clinical research, most analyses have focused on the results from the perspective of exploring the superiority of immunotherapy. Consequently, the role of chemotherapy as an important partner of immunotherapy in first-line combination therapy regimens for gastric cancer has attracted less attention. Here, we explore and analyze first-line immunotherapies for gastric cancer from the perspective of chemotherapy, to understand reasons for the failure of studies and to indicate directions for future clinical research.
