Management of prostate cancer in kidney transplant recipients

Kidney transplantation is the treatment of choice in eligible patients with end-stage kidney disease. Prostate cancer (PC) is the second most common cancer in men worldwide. The prevalence of chronic kidney disease worldwide is 13.4%. The management of localized PC in these patients is challenging due to immunosuppressive therapy and pelvic graft localization. High graft and recipient survival rates have resulted in higher numbers of these patients in our everyday practice. A retrospective analysis of male patients who had undergone kidney transplantation at our center between 2002 and 2022 and were diagnosed and treated for PC was performed. We analyzed the incidence, treatment methods, and follow-up of PC patients in this population. A total of 1079 male patients were transplanted. PC was diagnosed in 12 patients (8 after and 4 before transplantation). The incidence of PC was 1.11%. Radical prostatectomy was performed in 11 patients, and one patient was treated with radical radiotherapy. Eleven patients had stable graft function; 1 graftectomy was performed, unrelated to PC. Three patients were indicated for salvage radiotherapy, one is in process for prostate-specific membrane antigen positron emission tomography (PSMA PET CT), and 7 patients are in follow-up and without recurrence. Radical prostatectomy is a safe treatment method for localized PC in kidney transplant recipients, which does not impair graft function and survival.
