BackgroundWe currently know that prostate cancer (Pca) risk is reduced in patients undergoing kidney transplantation. However, its impact and treatment are not widely studied.MethodsThis was a retrospective study of male patients submitted to kidney transplantation in our center from 1980 to 2016 evaluating incidence, treatment, and follow-up of Pca in our population.ResultsIn 1805 patients undergoing kidney transplantation, 20 men were diagnosed with Pca, leading to an incidence of 1.1%. Median age at renal transplantation was 53.4 years with a median age at diagnosis of Pca of 61.2 years. Initial median prostate-specific antigen (PSA) was 6 ng/mL and Gleason score was 7 (3 + 4) in about 50% of cases. Bone metastasis developed in 10% and no visceral metastases were diagnosed. The majority of patients were submitted to radical prostatectomy and bilateral pelvic lymph node dissection. Some other cancers occurred in these patients such as skin and pulmonary cancers. In 35% of the cases, the graft was lost. The main cause of patient death was cardiovascular. The mean graft survival was about 14 years. The majority of patients are alive with functioning grafts (65%).ConclusionIn our center the clinical incidence of Pca in patients undergoing kidney transplantation is 1.1% and surgical treatment seems to be a good initial option.
