Pancreatic metastasis of renal cell carcinoma: presentation, treatment and survival.
OBJECTIVE
The pancreas is an uncommon site of metastasis from renal cell carcinoma, comprising 2% of pancreatic tumors removed in sizable series of operations. To our knowledge the role of operative resection in the setting of metastatic malignancy to the periampullary region has not yet been defined. We reviewed the records of 6 women and 2 men who underwent pancreatic resection due to malignancy and analyzed various prognostic factors.


METHODS
Between 1985 and 1995, 269 patients underwent pancreatic resection for malignancy at our hospitals, including 150 (56%) for pancreatic duct cancer, 65 (24%) for carcinoma of the ampulla, 27 (10%) for distal bile duct cancer, 19 (7%) for duodenal carcinoma and 8 (3%) for renal cell carcinoma metastasis. We reviewed the records of these latter 8 cases, and analyzed demographics, primary tumor type, disease-free interval, resection type, concomitant other organ resection, histological examination of the specimen, morbidity, adjuvant therapy and survival.


RESULTS
Pancreatic metastasis of renal cell carcinoma was managed by duodenopancreatectomy in 5 patients and total pancreatectomy in 3. There were no perioperative deaths. Mean tumor size in cases of a solitary pancreatic metastasis was 4 cm. (range 1.5 to 8). In the 3 patients treated with total pancreatectomy there were 2, 5 and 3 pancreatic metastases, respectively. Pathological examination revealed negative lymph nodes in all cases. Mean survival was 48 months. At study end 6 patients were alive at 24, 26, 30, 46, 84 and 88 months, while 2 died at 13 and 70 months, respectively.


CONCLUSIONS
We advocate aggressive surgical resection when possible. Surgical removal of metastatic lesions prolongs survival but radical lymph node dissection is not mandatory. We also recommend careful long-term followup of patients with a history of renal cell carcinoma.
