IMPORTANCE
Stratifying patients with biochemical recurrence (BCR) after primary treatment for prostate cancer based on the risk of prostate cancer-specific mortality (PCSM) is essential for determining the need for further testing and treatments.
OBJECTIVE
To evaluate the association of BCR after radical prostatectomy or radiotherapy and its current risk stratification with PCSM.
DESIGN, SETTING, AND PARTICIPANTS
This population-based cohort study included a total of 16 311 male patients with 10 364 (64%) undergoing radical prostatectomy and 5947 (36%) undergoing radiotherapy with curative intent (cT1-3, cM0) and PSA follow-up in Stockholm, Sweden, between 2003 and 2019. Follow-up for all patients was until death, emigration, or end of the study (ie, December 31, 2018). Data were analyzed between September 2022 and March 2023.
MAIN OUTCOMES AND MEASURES
Primary outcomes of the study were the cumulative incidence of BCR and PCSM. Patients with BCR were stratified in low- and high-risk according to European Association of Urology (EAU) criteria.
EXPOSURES
Radical prostatectomy or radiotherapy.
RESULTS
A total of 16 311 patients were included. Median (IQR) age was 64 (59-68) years in the radical prostatectomy cohort (10 364 patients) and 69 (64-73) years in the radiotherapy cohort (5947 patients). Median (IQR) follow-up for survivors was 88 (55-138) months and 89 (53-134) months, respectively. Following radical prostatectomy, the 15-year cumulative incidences of BCR were 16% (95% CI, 15%-18%) for the 4024 patients in the low D'Amico risk group, 30% (95% CI, 27%-32%) for the 5239 patients in the intermediate D'Amico risk group, and 46% (95% CI, 42%-51%) for 1101 patients in the high D'Amico risk group. Following radiotherapy, the 15-year cumulative incidences of BCR were 18% (95% CI, 15%-21%) for the 1230 patients in the low-risk group, 24% (95% CI, 21%-26%) for the 2355 patients in the intermediate-risk group, and 36% (95% CI, 33%-39%) for the 2362 patients in the high-risk group. The 10-year cumulative incidences of PCSM after radical prostatectomy were 4% (95% CI, 2%-6%) for the 1101 patients who developed low-risk EAU-BCR and 9% (95% CI, 5%-13%) for 649 patients who developed high-risk EAU-BCR. After radiotherapy, the 10-year PCSM cumulative incidences were 24% (95% CI, 19%-29%) for the 591 patients in the low-risk EAU-BCR category and 46% (95% CI, 40%-51%) for the 600 patients in the high-risk EAU-BCR category.
CONCLUSIONS AND RELEVANCE
These findings suggest the validity of EAU-BCR stratification system. However, while the risk of dying from prostate cancer in low-risk EAU-BCR after radical prostatectomy was very low, patients who developed low-risk EAU-BCR after radiotherapy had a nonnegligible risk of prostate cancer mortality. Improving risk stratification of patients with BCR is pivotal to guide salvage treatment decisions, reduce overtreatment, and limit the number of staging tests in the event of PSA elevations after primary treatment.

Review
PURPOSE
To provide a comprehensive update on the different techniques and outcomes of contemporary Single-Port (SP) Robotic Radical Prostatectomy (RARP) approaches.
METHODS
A literature review was performed to identify cohort studies that have utilized the purpose-built SP robotic platform (Intuitive Surgical Inc., Sunnyvale, California) for RARP. All published approaches of SP-RARP were included in our review. Baseline clinical, perioperative, and postoperative oncological and functional outcomes were collected from the included studies.
RESULTS
A total of 16 studies involving 1159 patients were identified. To date, five approaches of SP-RARP have been described, namely Transperitoneal, Extraperitoneal, Retzius-Sparing, Transperineal, and Transvesical. The surgical steps and clinical outcomes of the aforementioned approaches were discussed. While operating times were still faster in the Transperitoneal and Extraperitoneal cohorts, the novel and more regionalized Transvesical approach allowed for radical prostatectomy to be pursued in more patients with previous abdominal surgeries and contributed to significantly improved postoperative outcomes, including the earlier return of urinary continence and with most patients being discharged on the same day without any opioids.
CONCLUSION
Based on the existing literature, the introduction of SP-RARP not only enriched the repertoire of minimally-invasive surgical treatment options for prostate cancer but also provided the opportunity for urologists to develop new techniques that can improve perioperative outcomes and postoperative quality of life. Given the limited number of patients and heterogeneity in the patient selection and reporting of postoperative outcomes, further research remains necessary to better understand the different benefits and improve patient selection algorithms for the different techniques.

Review
OBJECTIVE
To compare the perioperative, oncological, and functional outcomes between single-port robot-assisted radical prostatectomy (SP-RARP) and multiport robot-assisted radical prostatectomy (MP-RARP) via a meta-analysis.
METHODS
For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until January 15, 2022. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR Guidelines. The risk ratio and weighted mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI).
RESULTS
Of the 368 retrieved abstracts, 41 underwent full-text review, and seven studies were included in the final analysis, comprising a total cohort of 1,934 cases of RARP (355 SP-RARP cases and 1,579 MP-RARP cases). Compared to MP-RARP, the SP-RARP group had less postoperative pain score (MD = -0.7, 95% CI -1 to -0.4, <0.001), morphine milligram equivalents usage (MD = -3.8, 95% CI -7.5 to -0.1, =0.04), hospital stay (MD = -1, 95% CI -1.8 to -0.1, =0.019), and urinary catheterization time (MD = -1.1, 95% CI -1.9 to -0.3, =0.008). However, the SP-RARP group had a longer console time than the MP-RARP group (MD = 5.3, 95% CI 2.6 to 7.9, <0.001).
CONCLUSIONS
Our study demonstrated that early results were mostly equivalent with the single-port approach. This technology may help to reduce the hospital stay and postoperative pain for patients undergoing radical prostatectomy compared to MP-RARP, without compromising the functional and early oncological outcomes.

Outcomes of Cytoreductive Radical Prostatectomy for Oligometastatic Prostate Cancer on Prostate-specific Membrane Antigen Positron Emission Tomography: Results of a Multicenter European Study.
BACKGROUND
De novo oligometastatic prostate cancer (omPCa) on prostate-specific membrane antigen (PSMA) positron emission tomography (PET) is a new disease entity and its optimal management remains unknown.
OBJECTIVE
To analyze the outcomes of patients treated with cytoreductive radical prostatectomy (cRP) for omPCa on PSMA-PET.
DESIGN, SETTING, AND PARTICIPANTS
Overall, 116 patients treated with cRP at 13 European centers were identified. Oligometastatic PCa was defined as miM1a and/or miM1b with five or fewer osseous metastases and/or miM1c with three or fewer lung lesions on PSMA-PET.
INTERVENTION
Cytoreductive radical prostatectomy.
OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS
Thirty-day complications according to Clavien-Dindo, continence rates, time to castration-resistant PCa (CRPC), and overall survival (OS) were analyzed.
RESULTS AND LIMITATIONS
Overall, 95 (82%) patients had miM1b, 18 (16%) miM1a, and three (2.6%) miM1c omPCa. The median prebiopsy prostate-specific antigen was 14 ng/ml, and 102 (88%) men had biopsy grade group ≥3 PCa. The median number of metastases on PSMA-PET was 2; 38 (33%), 29 (25%), and 49 (42%) patients had one, two, and three or more distant positive lesions. A total of 70 (60%) men received neoadjuvant systemic therapy, and 37 (32%) underwent metastasis-directed therapy. Any and Clavien-Dindo grade ≥3 complications occurred in 36 (31%) and six (5%) patients, respectively. At a median follow-up of 27 mo, 19 (16%) patients developed CRPC and eight (7%) patients died. The 1-yr urinary continence rate was 82%. The 2-yr CRPC-free survival and OS were 85.8% (95% confidence interval [CI] 78.5-93.7%) and 98.9% (95% CI 96.8-100%), respectively. The limitations include retrospective design and short-term follow-up.
CONCLUSIONS
Cytoreductive radical prostatectomy is a safe and feasible treatment option in patients with de novo omPCa on PSMA-PET. Despite overall favorable oncologic outcomes, some of these patients have a non-negligible risk of early progression and thus should be considered for multimodal therapy.
PATIENT SUMMARY
We found that patients treated at expert centers with surgery for prostate cancer, with a limited number of metastases detected using novel molecular imaging, have favorable short-term survival, functional results, and acceptable rates of complications.

Review
There are multiple treatment strategies for patients with localized prostate adenocarcinoma. In intermediate- and high-risk patients, external beam radiation therapy demonstrates effective long-term cancer control rates comparable to radical prostatectomy. In patients who opt for initial radiotherapy but have a local recurrence of their cancer, there is no unanimity on the optimal salvage approach. The lack of randomized trials comparing surgery to other local salvage therapy or observation makes it difficult to ascertain the ideal management. A narrative review of existing prospective and retrospective data related to salvage radical prostatectomy after radiation therapy was undertaken. Based on retrospective and prospective data, post-radiation salvage radical prostatectomy confers oncologic benefits, with overall survival ranging from 84 to 95% at 5 years and from 52 to 77% at 10 years. Functional morbidity after salvage prostatectomy remains high, with rates of post-surgical incontinence and erectile dysfunction ranging from 21 to 93% and 28 to 100%, respectively. Factors associated with poor outcomes after post-radiation salvage prostatectomy include preoperative PSA, the Gleason score, post-prostatectomy staging, and nodal involvement. Salvage radical prostatectomy represents an effective treatment option for patients with biochemical recurrence after radiotherapy, although careful patient selection is important to optimize oncologic and functional outcomes.

Meta-Analysis
CONTEXT
Surgical treatment is important for male lower urinary tract symptom (LUTS) management, but there are few reviews of the risks of reoperation.
OBJECTIVE
To systematically evaluate the current evidence regarding the reoperation rates of surgical treatment for LUTS in accordance with current recommendations and guidelines.
EVIDENCE ACQUISITION
Eligible studies published up to July 2023, were searched for in the PubMed (National Library of Medicine, Bethesda, MD, USA), Embase (Elsevier, Amsterdam, the Netherlands), and Web of Science™ (Clarivate™, Philadelphia, PA, USA) databases. STATA (StataCorp LP, College Station, TX, USA) software was used to conduct the meta-analysis. Random-effects models were used to calculate the pooled incidences (PIs) of reoperation and the 95% confidence intervals (CIs).
EVIDENCE SYNTHESIS
A total of 119 studies with 130,106 patients were included. The reoperation rate of transurethral resection of the prostate (TURP) at 1, 2, 3, and 5 years was 4.0%, 5.0%, 6.0%, and 7.7%, respectively. The reoperation rate of plasma kinetic loop resection of the prostate (PKRP) at 1, 2, 3, and 5 years was 3.5%, 3.6%, 5.7%, and 6.6%, respectively. The reoperation rate of holmium laser enucleation of the prostate (HoLEP) at 1, 2, 3, and 5 years was 2.4%, 3.3%, 5.4%, and 6.6%, respectively. The reoperation rate of photoselective vaporization of the prostate (PVP) at 1, 2, 3, and 5 years was 3.3%, 4.1%, 6.7%, and 7.1%, respectively. The reoperation rate of surgery with AquaBeam at 1, 2, 3, and 5 years was 2.6%, 3.1%, 3.0%, and 4.1%, respectively. The reoperation rate of prostatic artery embolization (PAE) at 1, 2, 3, and 5 years was 12.2%, 20.0%, 26.4%, and 23.8%, respectively. The reoperation rate of transurethral microwave thermotherapy (TUMT) at 1, 2, 3, and 5 years was 9.9%, 19.9%, 23.3%, and 31.2%, respectively. The reoperation rate of transurethral incision of the prostate (TUIP) at 5 years was 13.4%. The reoperation rate of open prostatectomy (OP) at 1 and 5 years was 1.3% and 4.4%, respectively. The reoperation rate of thulium laser enucleation of the prostate (ThuLEP) at 1, 2, and 5 years was 3.7%, 7.7%, and 8.4%, respectively.
CONCLUSION
Our results summarized the reoperation rates of 10 surgical procedures over follow-up durations of 1, 2, 3, and 5 years, which could provide reference for urologists and LUTS patients.

Meta-Analysis
IMPORTANCE
Patients with high-grade prostate cancer with low levels of prostate-specific antigen (PSA; <4 ng/mL) are at high risk of mortality, necessitating an improved treatment paradigm.
OBJECTIVE
To assess for these patients whether adding docetaxel to standard of care (SOC) treatment is associated with decreased prostate cancer-specific mortality (PCSM) and all-cause mortality (ACM).
DATA SOURCES
PubMed search from 2000 to 2022.
STUDY SELECTION
Five prospective randomized clinical trials (RCTs) performed in the US, France, and the United Kingdom evaluating SOC treatment with radiotherapy and androgen deprivation therapy (ADT) or with radical prostatectomy vs SOC plus docetaxel.
DATA EXTRACTION AND SYNTHESIS
Individual data were included from patients with nonmetastatic prostate cancer, a PSA level of less than 4 ng/mL, and a Gleason score of 8 to 10. Patients initiated treatment between February 21, 2006, and December 31, 2015 (median follow-up, 7.1 [IQR, 5.4-9.9] years). Data were analyzed on December 16, 2022.
MAIN OUTCOMES AND MEASURES
Hazard ratio (HR) of ACM and subdistribution HR (sHR) of PCSM adjusted for performance status (1 vs 0 or good health), Gleason score (9 or 10 vs 8), tumor category (T3-T4 vs T1-T2 or TX), and duration of ADT (2 years vs 4-6 months).
RESULTS
From a cohort of 2184 patients, 145 patients (6.6%) in 4 RCTs were eligible (median age, 63 [IQR, 46-67] years). Thirty-one patients died, and of these deaths, 22 were due to prostate cancer. Performance status was 0 for 139 patients (95.9%) and 1 for 6 patients (4.1%). A reduced but nonsignificant risk of ACM (HR, 0.51 [95% CI, 0.24-1.09]) and PCSM (sHR, 0.42 [95% CI, 0.17-1.02]) was associated with patients randomized to SOC plus docetaxel compared with SOC. The risk reduction in ACM (HR, 0.46 [95% CI, 0.21-1.02]) was more pronounced among patients with a performance status of 0 and was significant for PCSM (sHR, 0.30 [95% CI, 0.11-0.86]).
CONCLUSIONS AND RELEVANCE
Adding docetaxel to SOC treatment for patients who are in otherwise good health with a PSA level of less than 4 ng/mL and a Gleason score of 8 to 10 was associated with a significant reduction in PCSM and therefore has the potential to improve prognosis.

Review
Prolonged urinary incontinence represents one of the most severe complications after a radical prostatectomy procedure, significantly affecting patients' quality of life. In an attempt to ameliorate postprostatectomy continence rates, several sphincter preservation techniques have been reported. The purpose of this article is to report several different sphincter preservation techniques and identify the ones which affect postoperative outcomes the most. For our narrative review, PubMed was searched using the keywords "sphincter," "continence," "preservation," "techniques," and "prostatectomy." Other potentially eligible studies were identified using the reference lists of included studies. Sphincter preservation techniques can be summarized into bladder neck preservation, minimizing injury to the external urethral sphincter, and preserving the maximal length of the external sphincter and of the membranous urethra. Three anatomical structures must be recognized and protected in an attempt to maintain the sphincter complex: the bladder neck, the external urethral sphincter and the musculature of the membranous urethra. While there is strong evidence supporting the importance of bladder neck preservation, the role of maximal preservation of the external sphincter and of the intraprostatic part of the membranous urethra in improving continence rates has not yet been reported in a statistically significant manner by high-quality studies.
