[A Long Surviving Case of Resected Advanced Gastric Cancer with a Synchronous Adrenal Metastasis].

We report a long surviving case of gastric cancer with a synchronous adrenal metastasis in a patient who underwent curative resection. The patient was a 74-year-old man. Endoscopic examination revealed a type 3 gastric cancer in the proximal stomach. Abdominal computed tomography (CT) revealed a soft tissue density mass in the right adrenal gland and a high-density mass suspected as hemangioma in the left adrenal gland. The CT scan indicated no other distant metastasis. The patient had no endocrine abnormalities according to blood test results. Total gastrectomy with D2 lymphadenectomy and right adrenalectomy were performed in August 2003. On histopathological examination, the gastric tumor was diagnosed as a poorly differentiated adenocarcinoma. The histopathological findings of the right adrenal tumor were compatible with those of gastric cancer. The final diagnosis was por1, 105×65 mm, pT2 (SS), pN1 (#1: 2/8, #3: 1/11), P0, H0, CY0, pM1 (ADR), pStage Ⅳ. Two months after the surgery, the patient was treated with adjuvant TS-1 monotherapy (80 mg/m2 day 1-28/q6w) for 1 year 9 months. The patient had been in good health without a recurrence for more than 9 years 3 months after the operation.
