[A case of advanced gastric cancer effectively treated by combined chemotherapy of TS-1 and paclitaxel].

A patient was a 66-year-old male who had advanced gastric cancer with left gastric artery lymph node metastasis and invasion of pancreas and spleen. We thought a complete resection was difficult, so he was given neo-adjuvant chemotherapy by combined of TS-1 100 mg/day (2 weeks administration and 1 week rest) and Paclitaxel (PTX) 75 mg/body (day 1, 8). After 2 courses of this neo-adjuvant chemotherapy, tumor and lymph node swelling had decreased in size, and the tumor markers were reduced remarkably (CEA 9 2.5 --> 12.2 ng/ml, CA 19-9 2, 739 --> 19 3 U/ml). He underwent total gastrectomy and Roux-en Y reconstruction. No.4 d and No.7 lymph nodes were swollen and hard, but white with a neurotic-like appearance. On pathological study, no malignancy was seen in the lymph nodes, and a good partial response was achieved. In this chemotherapy, no side effects were seen, and he maintained good quality of life. TS-1/PTX therapy was thought to be an effective neoadjuvant chemotherapy for advanced gastric cancer.
