Curative resection of bladder cancer with pancreas head metastasis

Bladder cancer is the 9th most frequent cancer worldwide. Its incidence is increasing. The pancreas is an infrequent site of metastasis in relation to any type of malignancy. In this study, we report our experience with a patient who has undergone a pancreaticoduodenectomy for metastatic bladder cancer. A 61-year-old male was admitted with jaundice and pancreas head mass. He underwent robot assisted-cystectomy and ileal conduit for bladder cancer 7 months ago. Initial diagnosis under the imaging study was a resectable pancreas head cancer. However, we did not rule-out a metastatic bladder cancer. He underwent a classic pancreaticoduodenectomy. Based on histologic findings and immunohistochemistry results, a pancreas tumor with 4.9-cm sized metastatic urothelial carcinoma was diagnosed. He experienced no complication. He was discharged 11 days after the surgery. Four cycles of gemcitabine and cisplatin were administered. He remained recurrence-free of tumors for 16 months. Although the benefit of pancreatectomy for patient survival has been reported for metastases from renal cell carcinoma, it is unknown for bladder cancer because of no report. We believe that curative resection for metastasis to pancreas of urothelial carcinoma might be helpful for its management.
