Abstract
A 71-year-old woman underwent a distal gastrectomy for gastric cancer two years ago. The tumor was Stage IIIB composed of T3, N2, M0 and poorly differentiated adenocarcinoma (non-solid type) histologically.
TS-1 100 mg was given as postoperative adjuvant chemotherapy for 6 months. Abdominal computed tomography (CT) scan 25 months after gastrectomy revealed left adrenal metastasis, 30 mm in size. Despite three courses of chemotherapy with TS-1, the size of the adrenal metastasis increased to 35 mm. Positron emission tomography (PET) and CT showed accumulation with a standardized uptake value (SUV) only in the left adrenal metastasis. We diagnosed her as having left adrenal metastasis only, and perfomed a left adrenectomy. Histological examination revealed adrenal metastasis from gastric cancer. The patient did well without recurrence or metastasis for 10 months. We report a rare case of resected adrenal metastasis from gastric cancer.
