[A case of recurrence after resection of gastric cancer successfully treated by combination chemotherapy with CPT-11 and CDDP].

A 62-year-old man received total gastrectomy and splenectomy for gastric cancer in April 2008. The pathological diagnosis was stage IIIA(pT3N2M0). After the surgery, he was treated with oral administration of S-1 as postoperative adjuvant chemotherapy, but stopped after five months because of a drug eruption and general fatigue. He visited our hospital with complaints of abdominal pain and appetite loss in January 2010. Tumor marker(CEA)was elevated, and he was diagnosed as local recurrence with metastasis to the mediastinal/Virchow lymph node and thoracic vertebra after several examinations. He started to undergo combination chemotherapy with CPT-11 and CDDP. After three courses of treatment, local recurrence had almost disappeared and CEA level was normalized. After five courses of treatment, FDG-PET showed that all recurrent tumors had decreased in size and FDG uptake. We finished this combination chemotherapy after ten courses. After the treatment, PET-CT detected a slowly-growing right lung tumor. He received S6 segmentectomy of the right lung in May 2012. The pathological diagnosis was squamous cell carcinoma, and he was diagnosed as primary lung cancer(pT1aN0M0, stage I A). He was followed without showing any recurrence of gastric cancer in October 2012.
