Diffuse type advanced gastric cancer showing dismal prognosis is characterized by deeper invasion and emerging peritoneal cancer cell: the latest comparative study to intestinal advanced gastric cancer.

Abstract

Our research revealed for the first time that more dismal prognosis of D-AGC than I-AGC could be explained by propensity of deeper invasion and emerging peritoneal cancer cell, and histology itself did not have a prognostic value, hence indicating that present staging system works properly even in D-AGC as well as I-AGC. We must identify its molecular mechanism of both invasion and emerging peritoneal disease of D-AGC in order to improve the prognosis.
