title: [A case of remnant gastric cancer responding to neoadjuvant TS-1 therapy].
abstract: We report the case a 77-year-old male with remnant gastric cancer successfully treated with TS-1 as neoadjuvant chemotherapy. His treatment was daily oral administration of 100 mg TS-1 for 28 days. This therapy was safely carried out on an outpatient basis. The histological diagnosis of the resected stomach revealed complete disappearance of cancer cells in the stomach and the regional lymph nodes. This case suggests that TS-1 may have a potent therapeutic effect in neoadjuvant chemotherapy for recurrent gastric cancer.
