[A case of synchronous multiple primary cancers of the stomach and kidney]
Abstract:
In line with an increase in the incidence of multiple primary cancers, we have encountered a case of synchronous multiple primary cancers of the stomach and the left kidney. The patient, a 69-year-old male, visited our hospital after experiencing epigastric discomfort for three months. An advanced gastric cancer, Borrmann III type, was detected by endoscopic examination. Preoperative abdominal computed tomography also revealed a large low density mass occupying the upper part of the left kidney. On angiography, the left kidney showed a hypervascular mass, showing pooling and tumoral stains, thereby suggesting a renal cell carcinoma. The patient thus underwent a subtotal gastrectomy with an R2 lymph node dissection and a left radical nephrectomy. Histologically, the gastric lesion was a poorly-differentiated adenocarcinoma and the left renal lesion was a renal cell carcinoma of the clear cell type.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
