ABSTRACT
A 64-year-old man underwent long-term chemotherapy for advanced gastric cancer with para-aortic lymph node metastasis (cT3 N3 M0 P0, cStage IV). S-1 (120 mg/day) was orally administered for 14 days and CDDP (60 mg/m2) was administered 10 times by intravenous drip on day 8. Next, paclitaxel (PTX 80 mg/m2) was administered 12 times by intravenous drip on days 1, 8 and 15. After 10 S-1/CDDP courses and 12 paclitaxel courses, the lymph node swelling decreased in size, but the tumor increased. CPT-11 (100 mg/m2) was administered as third-line therapy by intravenous drip on days 1, 8, 15 and 22. A partial response (PR) was obtained after 2 courses, but due to severe pyloric stenosis, a food passage disorder appeared. We performed distal gastrectomy with D2 lymph node dissection. The histological diagnosis revealed a complete disappearance of cancer cells in the stomach and lymph nodes.
