Survey on prostate MRI reading and interpretation among urology residents in Italy, Brazil and the UK: a cry for help.

BACKGROUND: Prostate MRI is an essential tool in the diagnostic pathway of prostate cancer and its accurate reading helps decision to biopsy. The aim of this study was to assess the Urology residents' level of confidence in reading and interpreting prostate MRI, their interest in new learning opportunities and whether prostate MRI training should be part of the urology core curriculum during residency. METHODS: A 23-item survey has been created and distributed via Web to an international cohort of Urology residents over a 3-month period. Surveys obtained from Countries representing >10% total distribution of responses were analyzed. RESULTS: A total of 304 complete surveys were obtained from Urology residents, with a geographical prevalence from Europe (59.54%, 181/304) and South America (29.28%, 89/304). Only 17-20% of residents reported having received formal prostate MRI training during residency. Overall, <20% residents expressed to feel confident in reading and interpreting prostate MRI. As a result, >90% Urology trainees stated they would be willing to receive a formal training and would be interested in new learning opportunities in MRI reading and interpretation during residency, independently of their year of training. Despite UK Urology trainees showed to have a higher availability of MRI resources and MRI-based biopsies compared to the other countries, they still expressed concerns in regard to not feeling confident with MRI reading and interpretation and requested a formal training. CONCLUSIONS: This survey highlights the need for major learning opportunities and a formal training in prostate MRI reading and interpretation during urology residency.

Are localized prostate cancer biomarkers useful in the clinical practice?

Prostate cancer presents itself in a heterogeneous way with both aggressive and indolent forms. Despite the controversy surrounding its use, prostate-specific antigen screening ultimately leads to a greater number of diagnosed patients. One of the biggest challenges in clinical practice is to select the right patients for biopsy and, among diagnosed patients, to differentiate tumors with an indolent course from those with an unfavorable prognosis, in order to determine the best therapeutic decision for each case, avoiding unnecessary interventions. Currently, several types of biomarkers are available for clinical use in patients with prostate cancer, which include blood-based (prostate-specific antigen, Prostate Health Index®, 4K score®); urine sample-based (PCA3, SelectMDx®, ExoDx Prostate IntelliScore®); and biopsy, transurethral resection, or radical prostatectomy tissue-based (ConfirmMDx®, Oncotype®, Prolaris®, Decipher®). The aim of this review is to provide an overview of the current state of evidence and to highlight recent advances in the evaluation and diagnosis of prostate cancer, with emphasis on biomarkers related to diagnosis and to prognostic evaluation of localized prostate cancer.
