Core Tip

Core tip: This was a retrospective study to evaluate the surgical approach for pT4b gastric cancer with pancreatic head invasion. The overall 3-year survival rate of the patients in the gastrectomy plus en bloc pancreaticoduodenectomy group was significantly longer than that in the gastrectomy alone group. Curative resection of the invaded pancreas should be performed to improve survival after balancing the risk and survival benefit.
