[A Case of Long-Term Survival of a Patient with Gastric Cancer with Peritoneal Dissemination].

The patient was a 75-year-old man with a history of gastrectomy with combined resection of the transverse colon ligament for gastric cancer in July 2011. He was diagnosed with adenocarcinoma (tub2, tub1), L, Ant-Gre, type 2, pT4b (SI: transverse colon ligament) and pN3b, H0, M0, P0, CY0, Stage ⅢC.
