Аннотация
We report a case of advanced gastric cancer that showed a complete histological response to neoadjuvant chemotherapy. The patient, a 56-year-old man, was diagnosed as having advanced gastric cancer with lymph node metastases( cT3 cN1 cH0 cP0 cM0, cStageIIIA). He was initially treated with combined neoadjuvant chemotherapy comprising CPT-11+S-1. S-1(120 mg/day)was administered orally for 21 days, followed by CPT-11(130 mg/body)divon days 1 and 15. The primary lesion and lymph node metastases were diminished by 2 courses of chemotherapy, and no serious toxicities were observed. Distal gastrectomy and lymph node dissection(D2)were performed. Only a small ulcer was observed on the resected stomach. Histological examination of the resected stomach and lymph nodes revealed no remaining viable cancer cells. The patient has been doing well without any recurrence for 1 year since the start of treatment.
