Isolated Pancreatic Metastasis From Renal Clear Cell Renal Cell Carcinoma 29 Years After Radical Nephrectomy.

Isolated metastatic tumors of the pancreas from other origins are only 2-3% of pancreatic cancers, and renal cell carcinoma is the most common origin of metastasis. It is challenging to differentiate between pancreatic tumors and those with a history of renal cancer to optimize treatment and management of this tumor. Here, we present a case of isolated renal cell cancer metastasis to the pancreas, which occurred 29 years after the radical nephrectomy. Surgical resection and pancreatectomy is a feasible treatment because of the low rate of complication and favorable prognosis. However, isolated metastatic pancreatic cancer from renal cell cancer is rare and has relatively high risk of recurrence. Therefore, a larger sample size is necessary to evaluate long-term oncologic outcomes and to optimize diagnostic and therapeutic strategies.
