title: [A case of paraaortic lymph nodes metastases responding to TS-1 following surgery for gastric cancer].
abstract: A 58-year-old man underwent distal gastrectomy with a D2 lymph adenectomy for advanced gastric cancer (pStage IIIB). Seven months later, abdominal CT revealed multiple paraaortic lymph nodes metastases. Radiation therapy was not effective, so TS-1 chemotherapy was started (each treatment course consisted of daily oral administration of 100 mg TS-1 for 4 weeks followed by 2 drug-free weeks). The CT findings revealed that the metastatic lesion had shrunk markedly after the first course. A complete response was observed after the fifth course, and was maintained thereafter. The serum level of CEA decreased from 337 to 2.7 ng/ml after the third course, but gradually rose again and stayed between 30 and 50 ng/ml. Although the re-elevation of serum CEA level suggested the existence of a recurrent lesion, no sign of recurrence was found by radiographical or endoscopic examinations. Leukocytopenia and anemia (grade 2) were the only observed adverse effects. This patient continues to undergo outpatient treatment with good QOL.
