RESUMO
Cryotherapy is an ablative therapy that can be used to treat localized prostate cancer. In case of recurrence, treatment options are not well-defined, and their outcomes are unknown. We therefore collected all patients treated with radiotherapy after cryotherapy for prostate cancer recurrence in Nantes (France) between 2012 and 2019. We identified ten patients. After a median follow-up of 5 years, two patients presented late grade 3 toxicities; one patient presented a grade 3 rectal hemorrhage, and one had a grade 3 hematuria. Two patients relapsed at 61 and 62 months, and three patients died of other causes. Radiotherapy to treat local prostate cancer recurrence after cryotherapy seems feasible and effective in local control. These results do not allow us to recommend this technique in current practice but are encouraging for the conduct of prospective trials.

PURPOSE: The present study assessed the incidence and histopathological features of incidentally diagnosed prostate cancer (PCa) in specimens from radical cystoprostatectomy (RCP) for bladder cancer. The patient outcomes also were evaluated. METHODS: We retrospectively reviewed the histopathological features and survival data of 4,299 male patients who underwent a RCP for bladder cancer at 25 French centers between January 1996 and June 2012. No patients had preoperative clinical or biological suspicion of PCa. RESULTS: Among the 4,299 RCP specimens, PCa was diagnosed in 931 patients (21.7%). Most tumors (90.1%) were organ-confined (pT2), whereas 9.9% of them were diagnosed at a locally advanced stage (≥pT3). Gleason score was <6 in 129 cases (13.9%), 6 in 575 cases (61.7%), 7 (3 + 4) in 149 cases (16.0%), 7 (4 + 3) in 38 cases (4.1%), and >7 in 40 cases (4.3%). After a median follow-up of 25.5 months (interquartile range 14.2-47.4), 35.4% of patients had bladder cancer recurrence and 23.8% died of bladder cancer. Only 16 patients (1.9%) experienced PCa biochemical recurrence during follow-up, and no preoperative predictive factor was identified. No patients died from PCa. CONCLUSIONS: The rate of incidentally diagnosed PCa in RCP specimens was 21.7%. The majority of these PCas were organ-confined. PCa recurrence occurred in only 1.9% of cases during follow-up.
