Metachronous pancreatic metastasis of renal carcinoma: report of 4 cases

Abstract

Metastatic disease of the pancreas is a rare entity, and the most common primary tumor that occurs is carcinoma of the kidney. A retrospective observational study was performed in a hospital of third level of complexity during the period between January 2005 and December 2014. We analyzed the anatomical-pathological and clinical records of patients that after having undergone surgery by a neoplasia of the kidney, have subsequently undergone surgery of the pancreatic gland. Out of 177 nephrectomies, 4 patients with these characteristics were observed, being all cases metastatic pancreatic carcinoma of the kidney (2.25%). In all cases, surgery was the only treatment. To date, 3 of the 4 patients remain alive and free of disease. Pancreatic resection for metastases from renal cell cancer can be performed with acceptable morbidity and mortality rates, having a proved benefit in terms of patient survival.
