ABSTRACT: The patient was a 72-year-old woman diagnosed with advanced gastric cancer, hepatic portal lymph node and para-aortic lymph node metastases. After five courses of S-1/CDDP combination therapy, both the primary tumor and lymph node metastases disappeared clinically. She wished to continue chemotherapy instead of having a resection. After three more courses of S-1/CDDP therapy, gastric cancer and lymph node metastases were still completely regressed, but complications of carcinoma of the gallbladder were suspected. Gastrectomy was performed with cholecystectomy, and a histopathological examination revealed cancer cells remaining in the gastric submucosa and xanthogranulomatous cholecystitis. We consider surgical therapy for clinically completely disappearing advanced gastric cancer by chemotherapy, in addition to case report.
