BACKGROUND: HER2-positive gastric and gastroesophageal junction (GEJ) cancers have poor prognosis despite standard trastuzumab-based chemotherapy. Immune checkpoint inhibitors (ICIs) may enhance therapeutic efficacy when combined with trastuzumab.
METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines. PubMed, Cochrane Library, Embase, and Scopus were searched up to December 29, 2025. Studies evaluating ICIs plus trastuzumab and chemotherapy versus trastuzumab-based therapy alone were included. Kaplan-Meier curves were digitized using WebPlotDigitizer and reconstructed to individual participant data (IPD). Pooled survival outcomes, objective response rate (ORR), disease control rate (DCR), and safety were analyzed.
RESULTS: Six studies including 1,097 patients were included. ICIs plus trastuzumab and chemotherapy significantly improved median progression-free survival (10.4 vs. 8.27 months; HR 0.6951, p<0.0001) and overall survival (20.4 vs. 17.2 months; HR 0.8104, p=0.004) compared with control. ORR (OR 1.85, p<0.00001) and DCR (OR 2.46, p=0.006) were also superior. Grade ≥3 adverse events were similar between groups.
CONCLUSIONS: ICIs combined with trastuzumab and chemotherapy improve survival and response rates in HER2-positive gastric/GEJ cancers with manageable toxicity, supporting their integration into treatment strategies.
