[A case of gastric cancer with intensive peritoneal dissemination treated with long-term chemotherapy and surgery].

ABSTRACT

A 45-year-old man was transferred to our hospital because of advanced gastric cancer and peritoneal dissemination. After he received an S-1 plus cisplatin( CDDP) regimen for 6 courses, the primary lesion and ascites had disappeared. However, the primary lesion recurred, and he underwent treatment with 16 courses of an S-1 plus docetaxel regimen. He subsequently developed peripheral neuropathy, and was switched to the irinotecan (CPT-11) regimen. As he experienced appetite loss, it was impossible to continue the chemotherapy. Therefore, he underwent a salvage surgery and an R0 resection was performed. However, 9 months after the surgery, he experienced paraaortic lymph node recurrence and peritoneal dissemination. The patient died 13 months after the surgery.
