False positives in PIRADS (V2) 3, 4, and 5 lesions:relationship with reader experience and zonal location

PURPOSE: To investigate the effect of reader experience and zonal location on the occurrence of false positives (FPs) in PIRADS (V2) 3, 4, and 5 lesions on multiparametric (MP)-MRI of the prostate. MATERIALS AND METHODS: This retrospective study included 139 patients who had consecutively undergone an MP-MRI of the prostate in combination with a transrectal ultrasound MRI fusion-guided biopsy between 2014 and 2017. MRI exams were prospectively read by a group of inexperienced radiologists (cohort 1; 54 patients) and an experienced radiologist (cohort 2; 85 patients). Multivariable logistic regression analysis was performed to determine the association of experience of the radiologist and zonal location with a FP reading. FP rates were compared between readings by inexperienced and experienced radiologists according to zonal location, using Chi-square (χ2) tests. RESULTS: A total of 168 lesions in 139 patients were detected. Median patient age was 68 years (Interquartile range (IQR) 62.5-73), and median PSA was 10.9 ng/mL (IQR 7.6-15.9) for the entire patient cohort. According to multivariable logistic regression, inexperience of the radiologist was significantly (P = 0.044, odds ratio 1.927, 95% confidence interval [CI] 1.017-3.651) and independently associated with a FP reading, while zonal location was not (P = 0.202, odds ratio 1.444, 95% CI 0.820-2.539). In the transition zone (TZ), the FP rate of the inexperienced radiologists 59% (17/29) was significantly higher (χ2P = 0.033) than that of the experienced radiologist 33% (13/40). CONCLUSION: Inexperience of the radiologist is significantly and independently associated with a FP reading, while zonal location is not. Inexperienced radiologists have a significantly higher FP rate in the TZ

Systematic Review of Active Surveillance for Clinically Localised Prostate Cancer to Develop Recommendations Regarding Inclusion of Intermediate-risk Disease, Biopsy Characteristics at Inclusion and Monitoring, and Surveillance Repeat Biopsy Strategy

none38siContext: There is uncertainty regarding the most appropriate criteria for recruitment, monitoring, and reclassification in active surveillance (AS) protocols for localised prostate cancer (PCa). Objective: To perform a qualitative systematic review (SR) to issue recommendations regarding inclusion of intermediate-risk disease, biopsy characteristics at inclusion and monitoring, and repeat biopsy strategy. Evidence acquisition: A protocol-driven, Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)-adhering SR incorporating AS protocols published from January 1990 to October 2020 was performed. The main outcomes were criteria for inclusion of intermediate-risk disease, monitoring, reclassification, and repeat biopsy strategies (per protocol and/or triggered). Clinical effectiveness data were not assessed. Evidence synthesis: Of the 17 011 articles identified, 333 studies incorporating 375 AS protocols, recruiting 264 852 patients, were included. Only a minority of protocols included the use of magnetic resonance imaging (MRI) for recruitment (n = 17), follow-up (n = 47), and reclassification (n = 26). More than 50% of protocols included patients with intermediate or high-risk disease, whilst 44.1% of protocols excluded low-risk patients with more than three positive cores, and 39% of protocols excluded patients with core involvement (CI) >50% per core. Of the protocols, ≥80% mandated a confirmatory transrectal ultrasound biopsy; 72% (n = 189) of protocols mandated per-protocol repeat biopsies, with 20% performing this annually and 25% every 2 yr. Only 27 protocols (10.3%) mandated triggered biopsies, with 74% of these protocols defining progression or changes on MRI as triggers for repeat biopsy. Conclusions: For AS protocols in which the use of MRI is not mandatory or absent, we recommend the following: (1) AS can be considered in patients with low-volume International Society of Urological Pathology (ISUP) grade 2 (three or fewer positive cores and cancer involvement ≤50% CI per core) or another single element of intermediate-risk disease, and patients with ISUP 3 should be excluded; (2) per-protocol confirmatory prostate biopsies should be performed within 2 yr, and per-protocol surveillance repeat biopsies should be performed at least once every 3 yr for the first 10 yr; and (3) for patients with low-volume, low-risk disease at recruitment, if repeat systematic biopsies reveal more than three positive cores or maximum CI >50% per core, they should be monitored closely for evidence of adverse features (eg, upgrading); patients with ISUP 2 disease with increased core positivity and/or CI to similar thresholds should be reclassified. Patient summary: We examined the literature to issue new recommendations on active surveillance (AS) for managing localised prostate cancer. The recommendations include setting criteria for including men with more aggressive disease (intermediate-risk disease), setting thresholds for close monitoring of men with low-risk but more extensive disease, and determining when to perform repeat biopsies (within 2 yr and 3 yearly thereafter).noneWillemse, Peter-Paul M; Davis, Niall F; Grivas, Nikolaos; Zattoni, Fabio; Lardas, Michael; Briers, Erik; Cumberbatch, Marcus G; De Santis, Maria; Dell'Oglio, Paolo; Donaldson, James F; Fossati, Nicola; Gandaglia, Giorgio; Gillessen, Silke; Grummet, Jeremy P; Henry, Ann M; Liew, Matthew; MacLennan, Steven; Mason, Malcolm D; Moris, Lisa; Plass, Karin; O'Hanlon, Shane; Omar, Muhammad Imran; Oprea-Lager, Daniela E; Pang, Karl H; Paterson, Catherine C; Ploussard, Guillaume; Rouvière, Olivier; Schoots, Ivo G; Tilki, Derya; van den Bergh, Roderick C N; Van den Broeck, Thomas; van der Kwast, Theodorus H; van der Poel, Henk G; Wiegel, Thomas; Yuan, Cathy Yuhong; Cornford, Philip; Mottet, Nicolas; Lam, Thomas B LWillemse, Peter-Paul M; Davis, Niall F; Grivas, Nikolaos; Zattoni, Fabio; Lardas, Michael; Briers, Erik; Cumberbatch, Marcus G; De Santis, Maria; Dell'Oglio, Paolo; Donaldson, James F; Fossati, Nicola; Gandaglia, Giorgio; Gillessen, Silke; Grummet, Jeremy P; Henry, Ann M; Liew, Matthew; Maclennan, Steven; Mason, Malcolm D; Moris, Lisa; Plass, Karin; O'Hanlon, Shane; Omar, Muhammad Imran; Oprea-Lager, Daniela E; Pang, Karl H; Paterson, Catherine C; Ploussard, Guillaume; Rouvière, Olivier; Schoots, Ivo G; Tilki, Derya; van den Bergh, Roderick C N; Van den Broeck, Thomas; van der Kwast, Theodorus H; van der Poel, Henk G; Wiegel, Thomas; Yuan, Cathy Yuhong; Cornford, Philip; Mottet, Nicolas; Lam, Thomas B
