title: [A case of advanced gastric cancer with invasion of pancreas effectively treated by combined chemotherapy of TS-1 and paclitaxel (TXL)].
abstract: The patient was a 55-year-old woman who had unresectable advanced gastric cancer with celiac lymph node metastases and invasion of pancreas. The lesions were considered surgically incurable, so she was placed on neoadjuvant chemotherapy consisting of TS-1 and low-dose CDDP, for a total of 3 courses of TS-1 (100 mg/day, 12 weeks) and 2 courses of low-dose CDDP (10 mg/day, 100 mg). The only side effect of this chemotherapy was light anorexia, and the patient maintained a good QOL. After chemotherapy, the tumor had decreased partially in size, but there was little change in the abdominal lymph node metastases. She was considered to have little response and underwent palliative distal gastrectomy, because of the incomplete dissection of abdominal lymph node metastases. After the operation, she was treated with 2 courses of TS-1 100 mg/day (3 weeks administration and 2 weeks rest) and CDDP 70 mg or 50 mg/body (day 8). She had grade 3 anorexia. After discharge, she was treated by combined therapy of TS-1 100 mg/day (2 weeks administration and 2 weeks rest) and TXL 60 mg/body (day 1, 8, 15). After 2 courses of TS-1/TXL therapy, the abdominal lymph node metastases had decreased in size and the tumor markers were reduced remarkably: CEA 146.1-->26.9 ng/ml, and CA19-9,351.5-->210.6 U/ml. The patient received 5 courses of TS-1/TXL therapy, and she had no trouble with side effects. She maintained a good QOL. TS-1/TXL therapy was associated with few adverse events in hospital visits, and thought to be an effective adjuvant chemotherapy against advanced gastric cancer.
