Transurethral resection of the prostate in 85+ patients: a retrospective, multicentre study.

PURPOSE: To determine the safety and efficacy of transurethral resection of the prostate (TUR-P) in patients 85 years or older. METHODS: In this retrospective, multicentre study, patients equal or older than 85 years at the time of surgery (2015-2020) were included. Several pre-, peri- and postoperative parameters were collected. The main outcome criterion was spontaneous voiding with a post-void residual (PVR) volume < 100 ml at dismission and at 12 months after surgery. RESULTS: One hundred sixty-eight patients (median age: 87 years, interquartile range [IQR]: 86-89) were recruited. The patients took on average 5.2 permanent medications (3-8), 107 (64%) were anticoagulated preoperatively and neurological co-morbidities were present in 29 (17%). The indication for surgery was recurrent urinary retention in 66.3% (n = 110) with a mean retention volume of 849 ml. The mean PVR volume of the remaining 35% was 146 ml. Surgery was successfully completed in all patients. A perioperative surgical revision had to be performed in 3% and 13 patients (7.7%) required blood transfusion. After catheter removal, 85% of patients were able to void spontaneously with a PVR < 100 ml, and 14.3% were dismissed with a catheter. Twelve months data were available for 93 patients (55%). Of this cohort, 78 (83.9%) were able to void spontaneously with a PVR < 100 ml, 12 (12.9%) were on permanent catheterization. One patient (0.6%) died perioperatively. The only significant factor associated with an unsuccessful outcome was the number of permanent medications (6.8 vs. 5.0, p = 0.005). CONCLUSION: This retrospective multicentre study documents the safety and efficacy of TURP (monopolar and bipolar) in the old-old cohort.

Real-World Evidence of Triplet Therapy in Metastatic Hormone-Sensitive Prostate Cancer: An Austrian Multicenter Study.

INTRODUCTION: Two randomized trials demonstrated a survival benefit of triplet therapy (androgen deprivation therapy [ADT]) plus androgen receptor pathway inhibitor [ARPI] plus docetaxel) over doublet therapy (ADT plus docetaxel), thus changing treatment strategies in metastatic hormonesensitive prostate cancer (mHSPC). PATIENTS AND METHODS: We conducted the first real-world analysis comprising 97 mHSPC patients from 16 Austrian medical centers, among them 79.4% of patients received abiraterone and 17.5% darolutamide treatment. Baseline characteristics and clinical parameters during triplet therapy were documented. Mann-Whitney U test for continuous or X²-test for categorical variables was used. Variables on progression were tested using logistic regression analysis and tabulated as hazard ratios (HR), 95% confidence interval (CI). RESULTS: Of 83.5% patients with synchronous and 16.5% with metachronous disease were included. 83.5% had high-volume disease diagnosed by conventional imaging (48.9%) or PSMA PET-CT (51.1%). While docetaxel and ARPI were administered consistent with pivotal trials, prednisolone, prophylactic gCSF and osteoprotective agents were not applied guideline conform in 32.5%, 37%, and 24.3% of patients, respectively. Importantly, a nonsimultaneous onset of chemotherapy and ARPI, performed in 44.3% of patients, was associated with significantly worse treatment response (P = .015, HR 0.245). Starting ARPI before chemotherapy was associated with significantly higher probability for progression (P = .023, HR 15.781) than vice versa. Strikingly, 15.6% (abiraterone) and 25.5% (darolutamide) low-volume patients as well as 14.4% (abiraterone) and 17.6% (darolutamide) metachronous patients received triplet therapy. Adverse events (AE) occurred in 61.9% with grade 3 to 5 in 15% of patient without age-related differences. All patients achieved a PSA decline of 99% and imaging response was confirmed in 88% of abiraterone and 75% of darolutamide patients. CONCLUSIONS: Triplet therapy arrived in clinical practice primarily for synchronous high-volume mHSPC. Regardless of selected therapy regimen, treatment is highly effective and tolerable. Preferably therapy should be administered simultaneously, however if not possible, chemotherapy should be started first.
