Purpose: To evaluate biopsy-related complications and detection rates of any PCa and clinically significant PCa (csPCa, intended as grade group ≥ 2) between MRI-targeted TP fusion biopsies (TPBx) and TR ones (TRBx). Methods: We performed a multicentric study on 4841 patients who underwent fusion biopsy between 2016 and 2023. A case–control matching was performed to find comparable cohorts of 646 TPBx and 646 TRBx. Mean T test and Pearson chi-square tests were used to compare continuous and categorical variables. Results: Baseline characteristics were comparable between the cohorts, except for target location with a higher rate of anterior lesions in TPBx group. Complications were rare and no difference was found between the groups, with similar rates of infections after TRBx and TPBx (N = 5 (0.8%) vs N = 2 (0.3%), p 0.45). All patients in TRBx and 90.1% in TPBx group received antibiotic prophylaxis. A higher csPCa detection rate was found in TPBx over the group (50.5% vs 36.2%, p < 0.001). On average, positive targeted cores were increased in TPBx group, for any PCa (1.6 vs 1.4, p 0.04) and csPCa (1.0 vs 0.8, p 0.02). Among the limitations of study, we acknowledge the retrospective design and the possible under-reporting of complications. Conclusions: MRI-targeted fusion TPBx achieves a significantly higher csPCa detection than TRBx, with a diagnostic advantage for apical and anterior lesions. No significant differences were found in terms of complications that were rare in both groups, considering a widespread adoption of antibiotic prophylaxis. [ABSTRACT FROM AUTHOR]

Introduction: To investigate whether initial tumor burden at biopsy could predict adverse features after radical prostatectomy (RP) in International Society of Urological Pathology (ISUP) 1 prostate cancer (PCa) patients. Methods: This retrospective study was conducted in six referral centers. The cohort included patients with ISUP 1 PCa at systematic and MRI-targeted biopsy. We defined a high tumor burden at biopsy if ≥ 20% of cores were positive. The endpoint of the study was adverse features at RP, defined as ≥ pT3a stage and/or N1 and/or ISUP ≥ 3. Sensitivity analyses were performed to assess associations between different thresholds on biopsy (percentage of positive cores [PPC] ≥ 25%, ≥ 33%, ≥ 50%, bilateral positivity and positive cores > 3) and adverse features. As the number of targeted biopsies sampled may influence the number of positive cores, we used a virtual biopsy model in which all targeted biopsy results were interpreted as a single targeted biopsy. Results: A total of 312 contemporary patients were included. At final pathology, 99 patients (32%) had adverse features. In multivariate logistic regression analysis, there was no statistical association between PPC > 20% and adverse features (OR = 1.22; 95%CI:0.69–2.22, p = 0.5). In sensitivity analysis, tumor burden at biopsy was not associated with the risk of adverse features, regardless of the definition used (all p > 0.05). When we considered a unique virtual targeted biopsy, tumor burden remained not associated with adverse features (all p > 0.05). Conclusions: ISUP 1 PCa tumor burden at biopsy did not predict adverse features in this study, suggesting that it should not be used alone as an exclusion criterion when assessing eligibility for active surveillance.

Background: Given the increasing focus on patient safety in healthcare systems worldwide, understanding the impact of Continuous Quality Improvement Programs (QIPs) is crucial. QIPs, including Morbidity and Mortality Conferences (MMCs) and Experience Feedback Committees (EFCs), have been identified as effective strategies for enhancing patient safety culture. These programs engage healthcare professionals in the identification and analysis of adverse events to foster a culture of safety (ie the product of individual and group value, attitudes, and perceptions about quality and safety). This study aimed to determine whether patient safety culture differed regarding care provider participation in MMCs and EFCs activities. Methods: A cross-sectional web-only survey was conducted in 2022 using the Hospital Survey on Patient Safety Culture (HSOPS) among 4780 employees at an 1836-bed, university-affiliated hospital in France. We quantified the mean differences in the 12 HSOPS dimension scores according to MMCs and EFCs participation, using Cohen d effect size. We performed a multivariate analysis of variance to examine differences in dimension scores after adjusting for background characteristics. Results: Of 4780 eligible employees, 1457 (30.5%) participated in the study. Among the respondents, 571 (39.2%) participated in MMCs or EFCs activities. Participants engaged in MMCs or EFCs reported significantly higher scores in six out of twelve HSOPS dimensions, particularly in "Nonpunitive response to error", "Feedback and communication about error", and "Organizational learning" (Overall effect size = 0.14, 95% confidence interval = 0.11 to 0.17, P< 0.001). Notably, involvement in both MMCs and EFCs was associated with higher improvements in patient safety culture compared to non-participation or singular involvement in either program. However, certain dimensions such as "Staffing", "Hospital management support", and "Hospital handoffs and transition" showed no significant association with MMCs or EFCs participation, highlighting broader systemic challenges. Conclusion: The study confirms the positive association between participation in MMCs or EFCs and an enhanced culture of patient safety, emphasizing the importance of such programs in fostering an environment conducive to learning, communication, and nonpunitive responses to errors. While MMCs or EFCs are effective in promoting certain aspects of patient safety culture, addressing broader systemic challenges remains crucial for comprehensive improvements in patient safety.

Purpose: Accurate prediction of extraprostatic extension (EPE) is crucial for decision-making in radical prostatectomy (RP), especially in nerve-sparing strategies. Martini et al. introduced a three-tier algorithm for predicting contralateral EPE in unilateral high-risk prostate cancer (PCa). The aim of the study is to externally validate this model in a multicentric European cohort of patients. Methods: The data from 208 unilateral high-risk PCa patients diagnosed through magnetic resonance imaging (MRI)-targeted and systematic biopsies, treated with RP between January 2016 and November 2021 at eight referral centers were collected. The evaluation of model performance involved measures such as discrimination (AUC), calibration, and decision-curve analysis (DCA) following TRIPOD guidelines. In addition, a comparison was made with two established multivariable logistic regression models predicting the risk of side specific EPE for assessment purposes. Results: Overall, 38%, 48%, and 14% of patients were categorized as low, intermediate, and high-risk groups according to Martini et al.’s model, respectively. At final pathology, EPE on the contralateral prostatic lobe occurred in 6.3%, 12%, and 34% of patients in the respective risk groups. The algorithm demonstrated acceptable discrimination (AUC 0.68), comparable to other multivariable logistic regression models (p = 0.3), adequate calibration and the highest net benefit in DCA. The limitations include the modest sample size, retrospective design, and lack of central revision. Conclusion: Our findings endorse the algorithm's commendable performance, supporting its utility in guiding treatment decisions for unilateral high-risk PCa patients. [ABSTRACT FROM AUTHOR]
