Background The efficacy of pre-treated advanced gastric or gastroesophageal junction cancer (G/GEJC) with HER2 overexpressed (IHC 2+/3+) remains unsatisfactory. This retrospective real-world study aimed to analyse the safety and efficacy of disitamab vedotin (RC48) plus programmed death-1 (PD-1) inhibitor in pre-treated patients with advanced G/GEJC.
Xiao et al. (2025) studied this question.
