A 64-year-old man had undergone subtotal gastrectomy with a D2 lymphadenectomy for advanced carcinoma of the stomach with paraaortic lymph nodes metastases 12 months earlier. The histopathological findings revealed a well differentiated adenocarcinoma [type 2 macroscopic findings, SE, INF beta, ly2, v1, N2, M1 (LYM)]. On admission, biochemical investigations showed an elevation of CEA, CA19-9, and CA 125. An abdominal ultrasonography and a computed tomography (CT) revealed lymph node swelling of the paraaorta. After non-curative operation, he has received adjuvant chemotherapy with TS-1 plus CDDP. At first, 100 mg/day of TS-1 was orally administered for three weeks followed by two drug-free weeks, with CDDP (60 mg/m2/day) infused on day 8. Next, the treatment course consisted of four-week consecutive administration of TS-1 (80 mg/day) followed by two drug-free weeks, with biweekly infusion of CDDP at a dose of 15 mg/m2. The CT findings revealed that an almost complete reduction of the metastatic paraaortic lymphnodes was obtained after completion of course 1, and was maintained thereafter. No noteworthy adverse reactions were observed and the patient has a good QOL. The patient is now in a good health and continues to undergo low dose TS-1 plus CDDP chemotherapy as an outpatient.
