Pair-matched patient-reported quality of life and early oncological control following focal irreversible electroporation versus robot-assisted radical prostatectomy.

ABSTRACT: PURPOSE:The design, conduct and completion of randomized trials for curative prostate cancer (PCa) treatments are challenging. To evaluate the effect of robot-assisted radical prostatectomy (RARP) versus focal irreversible electroporation (IRE) on patient-reported quality of life (QoL) and early oncological control using propensity-scored matching. METHODS:Patients with T1c-cT2b significant PCa (high-volume ISUP 1 or any 2/3) who received unifocal IRE were pair-matched to patients who received nerve-sparing RARP. Patient-reported outcomes were prospectively assessed using the Expanded Prostate Cancer Index Composite (EPIC), AUA symptom score and Short Form of Health Survey (SF-12) physical and mental components. Oncological failure was defined as biochemical recurrence (RARP) or positive follow-up biopsies (IRE). Generalized mixed-effect models were used to compare IRE and RARP. RESULTS:50 IRE patients were matched to 50 RARP patients by propensity score. IRE was significantly superior to RARP in preserving pad-free continence (UC) and erections sufficient for intercourse (ESI). The absolute differences were 44, 21, 13, 14% for UC and 32, 46, 27, 22% for ESI at 1.5, 3, 6, and 12 months, respectively. The EPIC summary scores showed no statistically significant differences. Urinary symptoms were reduced for IRE and RARP patients at 12 months, although IRE patient initially had more complaints. IRE patients experienced more early oncological failure than RARP patients. CONCLUSIONS:These data demonstrated the superior preservation of UC and ESI with IRE compared to RARP up to 12 months after treatment. Long-term oncological data are warranted to provide ultimate proof for or against focal therapy.

Project description:ObjectiveTo evaluate: (i) safety, (ii) feasibility, and medium-term (iii) oncological and (iv) functional outcomes of salvage radical prostatectomy (sRP) for recurrent localised prostate cancer (PCa) following initial focal therapy using irreversible electroporation (IRE).Patients and methodsAn international, multicentre and retrospective analysis of prospectively collected data of patients that underwent sRP for recurrent localised PCa after initial primary IRE treatment. Data were reported on (i) surgical complications, (ii) feasibility of sRP reported by surgeons, (iii) time interval between IRE and sRP and pathology results, and (iv) urinary continence, erectile function, and quality of life.ResultsIn four participating centres, a total of 39 patients with a median (interquartile range [IQR]) age 64 (60-67) years were identified. No serious adverse events occurred during or following sRP and surgery was deemed feasible without difficulties. The median (IQR) time to recurrence following IRE was 14.3 (9.1-38.8) months. Pathology results showed localised disease in 21 patients (53.8%) and locally-advanced disease in 18 (46.2%). Positive surgical margins (PSMs) were observed in 10 patients (25.6%), of which six (15.4%) had significant PSMs. A persistent detectable prostate-specific antigen level was found in one case after sRP, caused by metastatic disease. One patient had a biochemical recurrence 6 months after sRP. These two cases, together with a PSM case, required additional therapy after sRP. After a median (IQR) follow-up of 17.7 (11.8-26.4) months, urinary continence and erectile function were preserved in 34 (94.4%) and 18 patients (52.9%), respectively, while quality of life remained stable.ConclusionsSalvage RP is safe and feasible for patients with recurrent localised PCa following initial IRE treatment. The medium-term oncological and functional outcomes are similar to primary RP. Strict patient selection for focal therapy and standardised follow-up is needed as some patients developed high-grade disease.

Project description:PurposeThis study investigated the oncological and functional outcomes of robot-assisted radical prostatectomy (RaRP) in high-risk and very high-risk prostate cancer patients.Materials and methodsOne hundred localized prostate cancer patients receiving RaRP from August 2015 to December 2020 were retrospectively enrolled. According to NCCN risk classification, patients were classified into two groups, below high-risk group, and high-risk/very high-risk group, to analyze continence outcome within postoperative year one and biochemical recurrence-free survival.ResultsThe mean age of the cohort was 69.7 ± 7.4 years with a median follow-up of 26.4 (range 3.3-71.3) months. Among them, 53%, and 47% patients were below high-risk group, and high-risk/very high-risk group, respectively. The median biochemical recurrence-free survival of the entire cohort was 53.1 months. The high-risk/very high-risk group without adjuvant treatment had significantly worse biochemical recurrence-free survival than the high-risk/very high-risk group with adjuvant treatment (19.6 vs. 60.5 months, p = 0.029). Rates of postoperative stress urinary incontinence at 1 week, 1 month, and 12 months were 50.7%, 43.7%, and 8.5%, respectively. High-risk/very high-risk patients had significantly higher rates of stress urinary incontinence at postoperative week 1 (75.8% vs. 28.9%) and month 1 (63.6% vs. 26.3%) than the below high-risk group (both p < 0.01). Rates of stress urinary incontinence after RaRP did not differ between two groups from postoperative 3 months to 12 months. The factor of high-risk / very high-risk group was a predictor of immediate but not for long-term postoperative stress urinary incontinence.ConclusionsHigh-risk and very high-risk prostate cancer patients receiving a combination of RaRP and adjuvant treatment had comparable biochemical recurrence-free survival to below high-risk prostate cancer patients. The high-risk/very high-risk factor impeded early but not long-term postoperative recovery of continence. RaRP can be considered a safe and feasible option for high-risk and very high-risk prostate cancer patients.
