Abstract

Introduction. Solid organ transplant increases the risk for muscle-invasive bladder cancer (MIBC). Although a common tumor, urothelial cell carcinoma (UCC) of the bladder in patients with kidney-pancreas transplants is scarcely reported. Case Presentation. A 65-year-old male with history of type 1 diabetes and a 14-year status post deceased donor pancreas-kidney transplant presented with 3 weeks of gross hematuria. CT scan showed multiple bladder masses. Transurethral resection of bladder tumor (TURBT) showed papillary UCC. 5 months later, the patient reported new-onset gross hematuria. TURBT showed MIBC. The patient elected for bladder-preserving TMT. On cystoscopy there was no gross evidence of carcinoma at 3.5 years of follow up. Discussion. Currently, no specific management guidelines target this population with MIBC. The first-line treatment for MIBC is radical cystectomy (RC) with neoadjuvant chemotherapy. For patients that are medically unfit or unwilling to undergo RC, trimodal therapy (TMT) is an alternative. TMT for bladder cancer consists of complete tumor resection with chemotherapy and radiation. This report demonstrates a unique case of a patient with kidney-pancreas transplant diagnosed with MIBC treated with TMT that has no evidence of gross tumorigenesis at 3.5 years after diagnosis. Our findings suggest that trimodal therapy should be considered for treatment of MIBC in patients with kidney-pancreatic transplants to preserve the donated allografts.
