Importance Multiparametric magnetic resonance imaging (MRI), with or without prostate biopsy, has become the standard of care for diagnosing clinically significant prostate cancer. Resource capacity limits widespread adoption. Biparametric MRI, which omits the gadolinium contrast sequence, is a shorter and cheaper alternative offering time-saving capacity gains for health systems globally. Objective To assess whether biparametric MRI is noninferior to multiparametric MRI for diagnosis of clinically significant prostate cancer. Design, Setting, and Participants A prospective, multicenter, within-patient, noninferiority trial of biopsy-naive men from 22 centers (12 countries) with clinical suspicion of prostate cancer (elevated prostate-specific antigen [PSA] level and/or abnormal digital rectal examination findings) from April 2022 to September 2023, with the last follow-up conducted on December 3, 2024. Interventions Participants underwent multiparametric MRI, comprising T2-weighted, diffusion-weighted, and dynamic contrast–enhanced (DCE) sequences. Radiologists reported abbreviated biparametric MRI first (T2-weighted and diffusion-weighted), blinded to the DCE sequence. After unblinding, radiologists reported the full multiparametric MRI. Patients underwent a targeted biopsy with or without systematic biopsy if either biparametric MRI or multiparametric MRI was suggestive of clinically significant prostate cancer. Main outcomes and measures The primary outcome was the proportion of men with clinically significant prostate cancer. Secondary outcomes included the proportion of men with clinically insignificant cancer. The noninferiority margin was 5%. Results Of 555 men recruited, 490 were included for primary outcome analysis. Median age was 65 (IQR, 59-70) years and median PSA level was 5.6 (IQR, 4.4-8.0) ng/mL. The proportion of patients with abnormal digital rectal examination findings was 12.7%. Biparametric MRI was noninferior to multiparametric MRI, detecting clinically significant prostate cancer in 143 of 490 men (29.2%), compared with 145 of 490 men (29.6%) (difference, −0.4 [95% CI, −1.2 to 0.4] percentage points; P = .50). Biparametric MRI detected clinically insignificant cancer in 45 of 490 men (9.2%), compared with 47 of 490 men (9.6%) with the use of multiparametric MRI (difference, −0.4 [95% CI, −1.2 to 0.4] percentage points). Central quality control demonstrated that 99% of scans were of adequate diagnostic quality. Conclusion and relevance In men with suspected prostate cancer, provided image quality is adequate, an abbreviated biparametric MRI scan, with or without targeted biopsy, could become the new standard of care for prostate cancer diagnosis. With approximately 4 million prostate MRIs performed globally annually, adopting biparametric MRI could substantially increase scanner throughput and reduce costs worldwide.

Radical prostatectomy is widely used as the primary modality of treatment for clinically localised prostate cancer. A considerable proportion of men will have adverse histopathologic features and could benefit from adjunctive treatments: mainly adjuvant or salvage radiation. This review focusses on the still unanswered questions: How to manage the patient after radical prostatectomy? Which patients need further treatment and which ones will not progress if not treated? How to refine patients selection for further treatments? What is the role for clinical nomograms and biomarkers and which ones are validated? When is it wise to propose adjuvant radiation therapy (RT) instead of observation with or without salvage RT? What is the optimal timing for the use of salvage RT and how to choose patients for each approach? This article discusses the evidence available in the current literature, providing a critical analysis of the controversies of each strategy.

AbstractBackgroundMetabolic syndrome (MetS) has a negative impact on functional recovery and complications after many surgical procedures.AimTo assess the role of Mets on functional outcomes and complications after radical prostatectomy (RP) for prostate cancer.Patients and MethodsComplete data were collected from 5758 patients, undergoing RP at a single referral centers in a 10‐year period and the presence of MetS before surgery was ascertained in 17.7% of them using a modified version of the IDF‐AHA/NHLBI criteria. Outcomes included 1‐year continence and potency rates, early (≤90 days) and late (>90 days) complications.ResultsPostoperative continence (no pads) was significantly less likely in MetS patients (75.4% vs 82.6%, P < .01), despite no difference in preoperative continence. Erections with or without therapy were reached in 55.8% of non‐MetS and 41.8% of MetS patients (P < .01), in this case a significant difference in preoperative function was seen. No differences in early and late complications, except for wound infections (5.8% vs 3.9%, P < .01) were observed.ConclusionsIn the present study RP was safe from the complications standpoint in MetS patients, but the presence of the syndrome was a significant risk factor for post‐RP incontinence and impotence.

Objective To investigate the association between smoking status and pathological response to cisplatin‐based neoadjuvant chemotherapy ( NAC ) and survival outcomes in patients with muscle‐invasive bladder cancer ( MIBC ) treated with radical cystectomy ( RC ). Patients and Methods We reviewed 201 patients treated with NAC and RC for cT 2– cT 4N0M0 BC between 01/1999 and 01/2015. Smoking status was categorised as: ‘never', ‘former', and ‘current' smoker. Pathological response to NAC was defined as: complete (ypT0N0), partial (ypTis/Ta/T1, N0), and no response (ypT2–4 or ypN+). Clinicopathological characteristics were analysed according to smoking status. Logistic regression analyses tested the association between smoking status and pathological response to NAC . Cox regression analyses tested risk factors associated with recurrence, overall ( OM ) and cancer‐specific mortality ( CSM ). Results Overall, there were 58 (28.9%) never smokers, 87 (43.3%) former smokers, and 56 (27.9%) current smokers. No response to NAC was more frequently noted in current smokers (73.2%; P = 0.007). Former smoker ( odds ratio [OR] 2.28; P = 0.024) and current smoker statuses ( OR 4.52; P < 0.001) were significantly associated with no response to NAC , after adjusting for age, gender, Charlson Comorbidity Index, and clinical stage. Similarly, current smoking status ( hazard ratio [HR] 2.14; P = 0.03) and extravesical pathological tumour stage ( HR 3.31; P < 0.001) were independently associated with an increased risk of recurrence after RC . Conclusion Cigarette smoking was significantly associated with adverse pathological response to cisplatin‐based NAC in patients with MIBC treated with RC . Current smokers were at significantly higher risk of disease recurrence as compared to former and never smokers.
