Abstract

Introduction: Renal cell carcinoma (RCC) is a relative rare tumor, accounting for approximately3% of adult malignancies. Renal cell carcinoma has a high metastatic potential and isrenowned for its ability to spread to almost any organ of the body. Pancreas is a rare site formetastasis from other primary cancers. Moreover, pancreatic metastasis is difficult todifferentiate and may be misdiagnosed as a primary pancreatic cancer. The aim of this studywas to review our cases of renal cell carcinoma that had metastasized to the pancreas afterradical nephrectomy.Methods: We did a retrospective review of the records of 4 patients with pathologicallyconfirmed RCC that had metastasized to the pancreas after radical nephrectomy.Results: Our group of 4 patients consisted of 2 men and 2 women. Their average age was58.7 years (± 10.51 years). The locations within the pancreas were the head, in 2 (50.0%) andthe body/tail in 2 (50.0%) patients. The pancreatic metastases were treated bypancreaticoduodenectomy in 2 patients, and by distal pancreatectomy in 2 patients. Mediansurvival duration was 109.0 (± 67.3 months) "Median" is associated with an interquartile range(25% to 75%). The number 67.3 appears to be a standard deviation which is associated withthe "mean".Conclusions: RCC is an unpredictable tumor that may result in a late metastasis even from anearly stage. Aggressive surgical management of pancreatic lesions offers a chance of long-termsurvival
