抄録

The number of the cases of multiple primary cancer has been increasing. The authers report two cases of synchronous double cancer of the kidney and stomach. In each case, renal cell carcinoma was incidentally diagnosed by abdominal ultrasonography (US) and computed tomography (CT) prior to a gastric operation. Both cancers were resected simultaneously.<br> Case 1: A 70-year-old man was admitted to the hospital because of an epigastric pain. Endoscopic studies and US revealed a gastric cancer in the upper third and multiple renal cell carcinomas in both kidneys. Wedge resection of the stomach and three partial nephrectomies were simultanously performed. Case 2: A 69-year-old woman was admitted for a resection of a gastric cancer in the antrum. CT and US revealed a renal cell carcinoma in the left kidney. Distal gastrectomy, D2 and a radical nephrectomy were simultanously performed. Both patients are disease-free for 5 years without any signs of recurrence.<br> Renal cell carcinomas are often silent especially in an early phase. In evaluating the CT and US findings before and after gastrectomy, the kidney should be examined, by entertaining a possible double cancer of it.
