A 63-year-old male complaining of jaundice was examined and diagnosed with advanced gastric cancer (type 3, tub 2, cT3, cN3, cH0, cM1, cStage IV), and obstructive jaundice due to lymph node metastasis. Since curative surgery was deemed not possible, we started chemotherapy with S-1+CDDP. S-1 (120 mg/day) was administered orally for 21 days, followed by CDDP (60 mg/m2) div on day 8. After the 9th course, a significant tumor reduction was obtained. Total gastrectomy and lymph node resection (D1) were performed. The histological diagnosis revealed complete disappearance of cancer cells in both the main tumor and lymph nodes. Herein we report this rare case with a view of the literature.
