OBJECTIVES: To provide a contemporary statement on focal therapy (FT) for localised prostate cancer (PCa) from an international and diverse group of physicians treating localised PCa, with the aim of overcoming the limitations of previous consensus statements, which were restricted to early adopters, and to offer direction regarding the various aspects of FT application that are currently not well defined. MATERIALS AND METHODS: The FocAL therapy CONsensus (FALCON) project began with a 154-item online survey, developed following a steering committee discussion and literature search. Invitations to participate were extended to a large, diverse group of professionals experienced in PCa management. From 2022 to 2023, a Delphi consensus study consisting of three online rounds was conducted using the Modified Delphi method. A 1-9 Likert scale was used for the survey, which was followed by an in-person expert meeting. The threshold for achieving consensus was set at 70% agreement/disagreement. Six main aspects of FT were covered: (i) patient selection; (ii) energy source selection; (iii) treatment approach; (iv) treatment evaluation and follow-up; (v) treatment cost and accessibility; and (vi) future perspectives. RESULTS: Of 246 initial participants, 148 (60%) completed all three rounds. Based on participant feedback, 27 new statements were added in the second round, and 33 questions related to personal expertise, for which consensus was not necessary, were excluded. After the third and final round, consensus had not been reached for 69 items. These items were discussed at the in-person meeting, resulting in a consensus of 57 additional items. Consensus was finally not reached on 12 items. Given the volume of data, the voting outcomes are summarised in this article, with a detailed breakdown presented in the form of figures and tables. CONCLUSIONS: The FALCON project delivered a significant consensus on the approach to FT for localised PCa. Additionally, it highlighted gaps in our knowledge that may provide guidance for future research.

BACKGROUND AND OBJECTIVE: Persistent prostatic specific antigen (PSA) represents a poor prognostic factor for recurrence after radical prostatectomy (RP). However, the impact of persistent PSA on oncologic outcomes in patients undergoing salvage RP is unknown. To investigate the impact of persistent PSA after salvage RP on long-term oncologic outcomes. MATERIAL AND METHODS: Patients who underwent salvage RP for recurrent prostate cancer between 2000 and 2021 were identified from twelve high-volume centers. Only patients with available PSA after salvage RP were included. Kaplan-Meier analyses and multivariable Cox regression models were used to test the effect of persistent PSA on biochemical recurrence (BCR), metastasis and any death after salvage RP. Persistent PSA was defined as a PSA-value ≥ 0.1 ng/ml, at first PSA-measurement after salvage RP. RESULTS: Overall, 580 patients were identified. Of those, 42% (n = 242) harbored persistent PSA. Median follow-up after salvage RP was 38 months, median time to salvage RP was 64 months and median time to first PSA after salvage RP was 2.2 months. At 84 months after salvage RP, BCR-free, metastasis-free, and overall survival was 6.6 vs. 59%, 71 vs. 88% and 77 vs. 94% for patients with persistent vs. undetectable PSA after salvage RP (all p < 0.01). In multivariable Cox models persistent PSA was an independent predictor for BCR (HR: 5.47, p < 0.001) and death (HR: 3.07, p < 0.01). CONCLUSION: Persistent PSA is common after salvage RP and represents an independent predictor for worse oncologic outcomes. Patients undergoing salvage RP should be closely monitored after surgery to identify those with persistent PSA.

PURPOSE: Recent advancements in the management of biochemical recurrence (BCR) following local treatment for prostate cancer (PCa), including the use of androgen receptor signaling inhibitors (ARSIs), have broadened the spectrum of therapeutic options. We aimed to compare salvage therapies in patients with BCR after definitive local treatment for clinically non-metastatic PCa with curative intent. METHODS: In October 2023, we queried PubMed, Scopus, and Web of Science databases to identify randomized controlled trials (RCTs) and prospective studies reporting data on the efficacy of salvage therapies in PCa patients with BCR after radical prostatectomy (RP) or radiation therapy (RT). The primary endpoint was metastatic-free survival (MFS), and secondary endpoints included progression-free survival (PFS) and overall survival (OS). RESULTS: We included 19 studies (n = 9117); six trials analyzed RT-based strategies following RP, ten trials analyzed hormone-based strategies following RP ± RT or RT alone, and three trials analyzed other agents. In a pairwise meta-analysis, adding hormone therapy to salvage RT significantly improved MFS (HR: 0.69, 95% CI: 0.57-0.84, p < 0.001) compared to RT alone. Based on treatment ranking analysis, among RT-based strategies, the addition of elective nodal RT and androgen deprivation therapy (ADT) was found to be the most effective in terms of MFS. On the other hand, among hormone-based strategies, enzalutamide + ADT showed the greatest benefit for both MFS and OS. CONCLUSIONS: The combination of prostate bed RT, elective pelvic irradiation, and ADT is the preferred treatment for eligible patients with post-RP BCR based on our analysis. In remaining patients, or in case of post-RT recurrence, especially for those with high-risk BCR, the combination of ADT and ARSI should be considered.

OBJECTIVES: This study aimed to test the association between of type and number of D'Amico high-risk criteria (DHRCs) with cancer-specific mortality (CSM) in high-risk prostate cancer patients treated with radical prostatectomy. MATERIALS AND METHODS: In the Surveillance, Epidemiology, and End Results database (2004-2016), we identified 31,281 radical prostatectomy patients with at least 1 DHRC, namely, prostate-specific antigen (PSA) >20 ng/mL (hrPSA), biopsy Gleason Grade Group (hrGGG) score of 4 and 5, or clinical tumor stage ≥T3 (hrcT). Multivariable Cox regression models and competing risks regression models (adjusting for other cause mortality) tested the association between DHRCs and 5-year CSM. RESULTS: Of 31,281 patients, 14,394 (67%) exclusively harbored hrGGG, 3189 (15%) harbored hrPSA, and 1781 (8.2%) harbored hrcT. Only 2132 patients (6.8%) harbored a combination of the 2 DHRCs, and 138 (0.6%) had all 3 DHRCs. Five-year CSM rates ranged from 0.9% to 3.0% when any individual DHRC was present (hrcT, hrPSA, and hrGGG, in that order), 1.6% to 5.9% when 2 DHRCs were present (hrPSA-hrcT, hrcT-hrGGG, and hrPSA-hrGGG, in that order), and 8.1% when all 3 DHRCs were present. Cox regression models and competing risks regression confirmed the independent predictor status of DHRCs for 5-year CSM that was observed in univariable analyses, with hazard ratios from 1.00 to 2.83 for 1 DHRC, 2.35 to 5.88 for combinations of 2 DHRCs, and 7.13 for all 3 DHRCs. CONCLUSIONS: Within individual DHRCs, hrcT and hrPSA exhibited weaker effects than hrGGG did. Moreover, a dose-response effect was identified according to the number of DHRCs. Accordingly, the type and number of DHRCs allow further risk stratification within the high-risk subgroup.

OBJECTIVES: To test for differences in overall and recurrence-free survival between laparoscopic and open surgical approaches in patients undergoing radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: We retrospectively identified patients treated for UTUC from 2010 to 2020 from our institutional database. Patients undergoing laparoscopic or open RNU with no suspicion of metastasis (cM0) were for the current study population. Patients with suspected metastases at diagnosis (cM1) or those undergoing other surgical treatments were excluded. Tabulation was performed according to the laparoscopic versus open surgical approach. Kaplan-Meier plots were used to test for differences in overall and recurrence-free survival with regard to the surgical approach. Furthermore, separate Kaplan-Meier plots were used to test the effect of preoperative ureterorenoscopy on overall and recurrence-free survival within the overall study cohort. RESULTS: Of the 59 patients who underwent nephroureterectomy, 29% (n = 17) underwent laparoscopic nephroureterectomy, whereas 71% (n = 42) underwent open nephroureterectomy. Patient and tumor characteristics were comparable between groups (p ≥ 0.2). The median overall survival was 93 and 73 months in the laparoscopic nephroureterectomy group compared to the open nephroureterectomy group (p = 0.5), respectively. The median recurrence-free survival did not differ between open and laparoscopic nephroureterectomies (73 months for both groups; p = 0.9). Furthermore, the median overall and recurrence-free survival rates did not differ between patients treated with and without preoperative ureterorenoscopy. CONCLUSIONS: The results of this retrospective, single-center institution showed that overall and recurrence-free survival rates did not differ between patients with UTUC treated with laparoscopic and open RNU. Furthermore, preoperative ureterorenoscopy before RNU was not associated with higher overall or recurrence-free survival rates.

OBJECTIVE: To assess differences in the distribution of type and number of D'Amico high-risk criteria (DHRCs) according to race/ethnicity (R/E) and their effect on cancer-specific mortality (CSM) in prostate cancer (PCa) patients treated with external beam radiotherapy (RT). METHODS: In the SEER database (2004-2016), we identified 31,002 PCa patients treated with RT with at least one DHRCs, namely PSA >20 ng/dL, biopsy Gleason Grade Group 4-5, and clinical T stage ≥T2c. Competing risks regression (CRR) model tested the association between DHRCs and 5-year CSM in all R/E subgroups. RESULTS: Of 31,002 patients, 20,894 (67%) were Caucasian, 5256 (17%) were African American, 2868 (9.3%) were Hispanic-Latino, and 1984 (6.4%) were Asian. The distributions of individual DHRCs and combinations of two DHRCs differed according to R/E, but not for the combination of three DHRCs. The effect related to the presence of a single DHRC, and combinations of two or three DHRCs on absolute CSM rates was lowest in Asians (1.2-6.8%), followed by in African Americans (2.3-12.2%) and Caucasians (2.3-12.1%), and highest in Hispanic/Latinos (1.7-13.8%). However, the opposite effect was observed in CRR, where hazard ratios were highest in Asians vs. other R/Es: Asians 1.00-2.59 vs. others 0.5-1.83 for one DHRC, Asians 3.4-4.75 vs. others 0.66-3.66 for two DHRCs, and Asians 7.22 vs. others 3.03-4.99 for all three DHRCs. CONCLUSIONS: R/E affects the proportions of DHRCs. Moreover, within the four examined R/E groups, the effect of DHRCs on absolute and relative CSM metrics also differed. Therefore, R/E-specific considerations may be warranted in high-risk PCa patients treated with RT.

BACKGROUND: To assess the association between of type and number of D'Amico high-risk criteria (DHRCs) with rates of cancer-specific mortality (CSM) in prostate cancer (PCa) patients treated with external beam radiotherapy (RT). METHODS: In the Surveillance, Epidemiology, and End Results database (2004-2016), we identified 34,908 RT patients with at least one DHRCs, namely prostate-specific antigen (PSA) >20 ng/dL (hrPSA), biopsy Grade Group (hrGG) 4-5, clinical T stage (hrcT) ≥T2c. Multivariable Cox regression models (CRM), as well as competing risks regression (CRR) model, which further adjust for other cause mortality, tested the association between DHRCs and 5-year CSM. RESULTS: Of 34,908 patients, 14,777 (42%) exclusively harbored hrGG, 5641 (16%) hrPSA, 4390 (13%) had hrcT. Only 8238 (23.7%) harbored any combination of two DHRCs and 1862 (5.3%) had all three DHRCs. Five-year CSM rates ranged from 2.4% to 5.0% when any individual DHRC was present (hrcT, hrPSA, hrGG, in that order), versus 5.2% to 10.5% when two DHRCs were present (hrPSA+hrcT, hrcT+hrGG, hrPSA+hrGG, in that order) versus 14.4% when all three DHRCs were identified. In multivariable CRM hazard ratios relative to hrcT ranged from 1.07 to 1.76 for one DHRC, 2.20 to 3.83 for combinations of two DHRCs, and 5.11 for all three DHRCs. Multivariable CRR yielded to virtually the same results. CONCLUSIONS: Our study indicates a stimulus-response effect according to the type and number of DHRCs. This indicates potential for risk-stratification within HR PCa patients that could be applied in clinical decision making to increase or reduce treatment intensity.

Mutations in the BRCA1 and BRCA2 tumour suppressor genes are associated with prostate cancer risk; however, optimal screening protocols for individuals with these mutations have been a subject of debate. Several prospective studies of prostate cancer incidence and screening among BRCA1/2 mutation carriers have indicated at least a twofold to fourfold increase in prostate cancer risk among carriers of BRCA2 mutations compared with the general population. Moreover, BRCA2 mutations are associated with more aggressive, high-grade disease characteristics at diagnosis, more aggressive clinical behaviour and greater prostate cancer-specific mortality. The risk for BRCA1 mutations seems to be attenuated compared with BRCA2. Prostate-specific antigen (PSA) measurement or prostate magnetic resonance imaging (MRI) alone is an imperfect indicator of clinically significant prostate cancer; therefore, BRCA1/2 mutation carriers might benefit from refined risk stratification strategies. However, the long-term impact of prostate cancer screening is unknown, and the optimal management of BRCA1/2 carriers with prostate cancer has not been defined. Whether timely localized therapy can improve overall survival in the screened population is uncertain. Long-term results of prospective studies are awaited to confirm the optimal screening strategies and benefits of prostate cancer screening among BRCA1/2 mutation carriers, and whether these approaches ultimately have a positive impact on survival and quality of life in these patients.

PURPOSE: Guidelines suggest less favorable cancer control outcomes for local tumor destruction in T1a renal cell carcinoma patients with tumor size 3.1-4 cm. We compared cancer-specific mortality between cryoablation vs heat-based thermal ablation in patients with tumor size 3.1-4 cm, as well as in patients with tumor size ≤3 cm. MATERIALS AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2018), we identified patients with clinical T1a stage renal cell carcinoma treated with cryoablation or heat-based thermal ablation. After up to 2:1 ratio propensity score matching between patients treated with cryoablation vs heat-based thermal ablation, we addressed cancer-specific mortality relying on competing risks regression models, adjusted for other-cause mortality and other covariates (age, tumor size, tumor grade, and histological subtype). RESULTS: Of 1,468 assessable patients with tumor size 3.1-4 cm, 1,080 vs 388 were treated with cryoablation vs heat-based thermal ablation, respectively. After up to 2:1 propensity score matching that resulted in 757 cryoablations vs 388 heat-based thermal ablations, in multivariable competing risks regression models, heat-based thermal ablation was associated with higher cancer-specific mortality (HR:2.02, P < .001), relative to cryoablation. Of 4,468 assessable patients with tumor size ≤3 cm, 3,354 vs 1,114 were treated with cryoablation vs heat-based thermal ablation, respectively. After up to 2:1 propensity score matching that resulted in 2,217 cryoablations vs 1,114 heat-based thermal ablations, in multivariable competing risks regression models, heat-based thermal ablation was not associated with higher cancer-specific mortality (HR:1.13, P = .5) relative to cryoablation. CONCLUSIONS: Our findings corroborated that in cT1a patients with tumor size 3.1-4 cm, cancer-specific mortality is twofold higher after heat-based thermal ablation vs cryoablation. Conversely, in patients with tumor size ≤3 cm either ablation technique is equally valid. These findings should be considered at clinical decision making and informed consent.
