Resection of pancreatic metastasis from renal cell carcinoma and an early gastric cancer.

An 81-year-old woman, who had undergone left radical nephrectomy for renal cell carcinoma 17 years previously, was found to have a mass approximately 5cm in diameter in the body of the pancreas and an early gastric cancer. The patient was suspected of having pancreatic metastasis from renal cell carcinoma and an early gastric cancer and underwent distal pancreatectomy, splenectomy, and distal gastrectomy. Histologic examination showed that the pancreatic tumor was a clear cell renal cell carcinoma that had metastasized to the body of the pancreas and that the gastric cancer was a well-differentiated adenocarcinoma that had invaded the mucosa. Twenty months after the operation, the patient was well, without any evidence of recurrence. Renal cell carcinoma metastatic to the pancreas with gastric cancer rarely occurs, and surgical resection might have improved the quality of life in this patient. Careful long-term follow-up is necessary for patients who have undergone surgery for renal cell carcinoma.
