[A case of advanced gastric cancer responding to neoadjuvant TS-1/CDDP therapy].
A 62-year-old advanced gastric cancer patient with bulky N2 lymph node metastases was treated by neoadjuvant chemotherapy with TS-1 and CDDP. TS-1 (100 mg/body/day) was orally administered for 3 weeks followed by a drug-free 2-week period as 1 course, and 75 mg/body/day of CDDP was administered by intravenous drip on day 8. After the first course, the primary lesion and the regional lymph node metastases showed partial response in terms of size. No serious drug adverse reaction was observed. During the second course, urgent total gastrectomy with distal pancreatectomy and splenectomy was performed for massive bleeding from a deep gastric peptic ulcer. The histopathological findings showed complete response of the carcinoma as primary lesion except for two sites of minimal lymphatic permeation and one lymph node (No. 8a) metastasis. The combined use of TS-1 and CDDP is useful as neoadjuvant chemotherapy for advanced gastric cancer.
