Diagnosis and treatment of prostate cancers in renal-transplant recipients

BACKGROUND: There is no consensus regarding prostate cancer in renal-transplant recipients (RTR). A questionnaire evaluating prostate cancer screening after transplantation and assessing the number, diagnostic modalities, treatment, and outcome of prostate cancer cases was mailed to 22 French renal-transplant centers. RESULTS: Among 1,680 RTR in 1998, 11 (0.65%) cases of prostate cancer were diagnosed, and among the 2,338 recipients followed up, 28 (1%) cases of prostate cancer have been diagnosed and treated. Median ages at diagnosis and at transplantation were 63 and 58, respectively. Clinical stages were T1 50% and T2 25%. Eighteen patients had a Gleason score under 7. At 18 months of mean follow-up, 2 men had died from prostate cancer, and in the curative treatment group, 16 of 17 men were alive with no evidence of disease. CONCLUSIONS: The incidence of prostate cancer in RTR appeared to be higher than expected. Prostate specific antigen (PSA) testing should be performed routinely each year in renal transplantation centers.
