Abstract
A 54-year-old man was seen at the hospital because of epigastralgia. Endoscopic and upper gastrointesti-nal x-ray examinations revealed a cancer of the stomach. Abdominal ultrasonography and CT scan detected a tumor at superior segment of the left kidney which was diagnosed as renal cell carcinoma by magnetic resonance imaging (MRI) and renal angiography.
Based on a consideration that this synchronous double cancer could be successfully resected on an onestep approach, total gastrectomy with D2 lymph node dissection, cholecystectomy, distal pancreatectomy, splenectomy and radical nephrectomy were performed. Histopathologically, the gastric cancer showed poorly differentiated adenocarcinoma (SS, ly3, ow(-), aw(-), n2(+), stage IIIa) and the renal cell carcinoma was clear cell subtype (G2, INFα, pT2, pN0, pM0, pV0, stage II) . In addition, it was found that the gastric cancer showed aneuploidy, while renal cell carcinoma was diploidy by DNA analysis.
Postoperative course was uneventful, and now he is healthy without any recurrence signs.
