ClinConnect Summary

Peritoneal metastasis is the most common pattern of disease relapse and is attributed to the dismal prognosis of the gastric cancer. The National Comprehensive Cancer Network (NCCN) guidelines suggest that systemic chemotherapy is the first-line standard strategy, and chemotherapy combined with trastuzumab for patients with positive HER-2. HIPEC can significantly improve survival in peritoneal metastasis from gastric cancer. PD-1/PD-L1 antibody has shown promising outcomes for unresectable or metastatic solid tumors. The present study aimed to evaluate the safety and efficacy of HIPEC combi...
