[Late pancreatic metastasis of renal carcinoma. Description of 2 cases and review of the literature].

Authors report two cases of pancreatic metastasis from renal clear cell carcinoma, discovered in a 62 years-old-man and in a 73 years-old woman, respectively 17 and 11 years after undergoing curative nephrectomy for primary tumor. Immunological forces and slow doubling times of tumor may explain this type of late recurrence, whereas, the endocrine status is lacking in importance. The risk of a recurrence of tumour ten years or later after nephrectomy suggests a lifelong follow-up of patients with an history of renal cell carcinoma.
