Focal instead of whole gland ablation for prostate cancer has been proposed to decrease treatment morbidity. We sought to determine differences in erectile function and urinary continence after focal and whole gland ablation for prostate cancer.From 2009 to 2018, 346 patients underwent high intensity focused ultrasound or cryotherapy for prostate cancer. Urinary continence was defined as use of no pads and sexual potency as enough erection for sexual penetration. Logistic regressions to treatment groups and covariates age, prostate specific antigen, International Society of Urological Pathology grading, prostate volume and energy modality were performed to access the effect of focal therapy in sexual potency and urinary continence after 3 and 12 months. IIEF-5 (International Index of Erectile Function) and I-PSS (International Prostate Symptom Score) questionnaires were evaluated. Propensity score matching was performed to adjust for potential baseline differences between groups.After exclusion, 195 post-focal therapy and 105 post-whole gland therapy patients were included in analysis. No significant difference was seen in baseline I-PSS and IIEF-5 scores. In multivariate models focal therapy was the most important factor related to sexual potency at 3 (OR 7.7) and 12 months (OR 3.9). Median IIEF-5 score at 3 months was 12 and 5 (p0.001), and at 12 months was 13 and 9 (p=0.04) in focal therapy and whole gland therapy groups, respectively. Focal therapy was the only factor related to continence (OR 0.7, p0.001). Results remained significant after propensity score matching.Focal ablation instead of whole gland therapy is the most important factor related to better sexual and urinary continence recovery after high intensity focused ultrasound and cryotherapy for prostate cancer.

We report oncologic outcomes in patients treated with focal therapy for prostate cancer.We retrospectively analyzed a single institution cohort of men with localized prostate cancer who received focal therapy using high intensity focused ultrasound or cryotherapy from 2009 to 2018. Focal therapy was offered for low or intermediate risk disease (prostate specific antigen less than 20 ng/ml, Gleason score 7 or less and clinical stage T2b or less). Patients with previous prostate cancer treatment or less than 6 months of followup were excluded from study. Failure was defined as local or systemic salvage treatment, a positive biopsy Gleason score of 7 or greater in-field or out-of-field in nontreated patients, prostate cancer metastasis or prostate cancer specific death. Cox regression analysis was done to identify independent predictors of failure after focal therapy.Of the 309 patients included in study 190 and 119 were treated with high intensity focused ultrasound and cryotherapy, respectively. Median followup was 45 months. At 1, 3 and 5 years the failure-free survival rate was 95%, 67% and 54%, and the radical treatment-free survival rate was 99%, 79% and 67%, respectively. The 5-year metastasis-free survival rate was 98% and no prostate cancer specific death was registered in this cohort. Before focal therapy a biopsy Gleason score of 7 (3 + 4) or greater (HR 2.4, p0.001) and nadir prostate specific antigen (HR 2.2, p0.001) were independently associated with failed focal therapy. In the salvage focal therapy setting in-field recurrence after primary focal therapy was associated with poorer failure-free survival (p=0.02).Almost half of the men were free of focal therapy failure 5 years after treatment. Still, a significant proportion experienced recurrence at the midterm followup. The preoperative biopsy Gleason score and nadir prostate specific antigen were significantly associated with treatment failure.

We assessed the impact of focal therapy on perioperative, oncologic and functional outcomes in men who underwent salvage robotic assisted radical prostatectomy compared to primary robotic assisted radical prostatectomy.Focal therapy was performed in patients presenting with Gleason score 3 + 3 or 3 + 4, clinical stage cT2a or less, serum prostate specific antigen 15 ng/ml or less, unilateral positive biopsy, maximum length of any positive core less than 10 mm and life expectancy greater than 10 years. Focal therapy was defined as target ablation of the index lesion plus a 1 cm safety margin in the normal ipsilateral prostatic parenchyma. The salvage group included 22 men who underwent salvage prostatectomy after focal therapy failure. The primary group was defined using matched pair 1:2 selection of 44 of 2,750 patients treated with primary prostatectomy. The primary and secondary end points were the between group differences in functional and oncologic outcomes, respectively.Complication rates were comparable (p0.05). Pad-free probability was comparable between the groups at 1 and 2 years (p = 0.8). Recovery of erectile function was significantly lower after salvage robotic assisted radical prostatectomy (p = 0.008), which also showed a significantly lower probability of cumulative biochemical recurrence-free survival compared to primary robotic assisted radical prostatectomy (56.3% vs 92.4% at 2 years, p = 0.001). Salvage prostatectomy demonstrated a significantly increased risk of biochemical recurrence (HR 4.8, 95% CI 1.67-13.76, p = 0.004). Study limitations included the retrospective nature, the lack of randomization and the short followup.Salvage robotic assisted radical prostatectomy after focal therapy failure is feasible with acceptable complication rates. However, patients assigned to primary focal therapy should be advised about a poorer prognosis in terms of oncologic control and lower erectile recovery rates in case of a future salvage surgery.
