OBJECTIVE: To review the incidence and long-term outcomes of squamous cell carcinoma (SCC) of the bladder in patients after kidney transplantation.
METHODS: Between January 1976 and March 2013, five patients from one center (0.0013%) developed SCC of the bladder after undergoing a deceased donor kidney transplant. Their relevant risk factors included long-term self-intermittent catheterization/indwelling catheter (n = 2), smoking history (n = 2), and a prior history of cyclophosphamide treatment for vasculitis (n = 1). Primary outcome variables were overall patient survival and latency period between transplantation and SCC diagnosis.
RESULTS: The duration of long-term follow-up was 94 ± 89 (range: 4-239) months. The latency period between transplantation and bladder SCC was 87 ± 87 (range: 2-228) months, and all five patients were immunosuppressed with tacrolimus, mycophenolate mofetil, and prednisone. Four patients had suspected metastases upon presentation, and one patient presented with organ-confined disease. This patient underwent a radical cystectomy and remains disease free eight months post-operatively. Despite radical treatment, the remaining four patients died from metastatic disease 7 ± 4.4 (range: 2-11) months after their initial diagnosis.
CONCLUSION: SCC of the bladder has a poor prognosis particularly in renal transplant patients. Early detection with flexible cystourethroscopy in patients with risk factors for SCC may improve long-term outcomes in this patient cohort.
