Abbreviated Protocols versus Multiparametric MRI for Assessment of Extraprostatic Extension in Prostatic Carcinoma: A Multireader Study.

BACKGROUND/AIM: Prostate multiparametric magnetic resonance imaging (mpMRI) is the reference imaging modality for extraprostatic extension of disease (EPE) assessment. We aimed to compare the diagnostic accuracy of different abbreviated MRI protocols to the standard prostate mpMRI in the identification of EPE of PCa. PATIENTS AND METHODS: Fifty patients were retrospectively enrolled. Dual-pulse (dpMRI) and biparametric (bpMRI) abbreviated protocols were obtained from mpMRI. The performance of two experienced radiologists and two radiology residents was correlated with a reference standard and compared. Inter and intra-reader agreements were evaluated. RESULTS: All protocols were strongly correlated to the reference standard (p≤0.001). A significant difference was found between dpMRI and mpMRI (p=0.009), no differences emerged between bpMRI and mpMRI (p=0.27). All readers showed moderate agreement (ĸ=0.47, ĸ=0.50 and ĸ=0.53 for dpMRI, bpMRI and mpMRI, respectively). Intra-reader agreement was good (all ĸ values ≥0.70). CONCLUSION: Only bpMRI showed similar diagnostic performance to mpMRI, thus appearing as a feasible alternative to the standard protocol for EPE detection.

Quality of Life Assessment With Orthotopic Ileal Neobladder Reconstruction After Radical Cystectomy: Results From a Prospective Italian Multicenter Observational Study.

OBJECTIVE: To assess health-related quality of life (HRQoL) parameters in patients who received radical cystectomy (RC) with ileal orthotopic neobladder (IONB) reconstruction and to identify clinic-pathologic predictors of HRQoL. PATIENTS AND METHODS: From January 2010 to December 2013, a multicenter, retrospective on 174 RC-IONB patients was carried out. All patients completed the following questionnaires: the European Organization for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the IONB-Patient Reported Outcome (IONB-PRO). Univariate and multivariate analyses were computed to identify clinic-pathologic predictors of HRQoL. RESULTS: Median age was 66 years (range, 31-83), and 91.4% of patients were men. Median follow-up period was 37 months (range, 3-247). The EORTC QLQ-C30 revealed that age >65 years, absence of urinary incontinence, and absence of peripheral vascular disease were independent predictors of deteriorated body image. A follow-up > 36 months and the presence of urinary incontinence were independent predictors of worsened urinary symptoms, whereas the absence of urinary incontinence was an independent predictor of a worsened body image according to EORTC QLQ-BLM30 results. A follow-up >36 months and the absence of urinary incontinence were independent predictors of better functioning in terms of relational life, emotional life, and fatigue as revealed by the IONB-PRO. CONCLUSION: Age, presence of urinary incontinence, length of follow-up, and comorbidity status may influence postoperative HRQoL and should all be taken into account when counseling RC-IONB patients.
