Multiparametric MRI (mpMRI) is the standard for local staging, but its sensitivity for EPE remains limited, and its interpretation is subject to inter-reader variability. In this narrative review, we aim to create an overview of contemporary strategies for the preoperative detection of EPE. We searched PubMed, Embase, Web of Science, and Google Scholar, focusing on studies published between 2015 and 2025 including articles evaluating clinical parameters, mpMRI features, nomograms, radiomics, machine learning, and deep learning models for EPE prediction. The analyzed literature was compared with respect to diagnostic performance, validation strategy, and clinical applicability of individual methods. Clinical parameters and traditional nomograms provide moderate accuracy for EPE detection. mpMRI improves staging, with tumor\u2013capsule contact length as the most important single imaging marker. Radiomics-based and machine-learning models matched and occasionally outperform conventional approaches, achieving AUC values ranging from 0.75 to 0.85. Deep-learning models demonstrated similar performance by directly analyzing imaging data, although most lacked external validation and were sensitive to dataset heterogeneity. Several radiomics and deep learning models demonstrated performance comparable to, and in selected studies exceeding, expert radiologist assessment. Binary EPE classification has limited clinical value, while side-specific and graded EPE assessment offers a more clinically relevant approach. Translation of these tools into routine practice will require multimodal, side-specific, and externally validated models supported by automated segmentation and explainable artificial intelligence frameworks.<\/jats:p>","DOI":"10.3390\/cancers18030456","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T13:04:46Z","timestamp":1769778286000},"page":"456","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Contemporary Preoperative Detection of Extraprostatic Extension in Prostate Cancer"],"prefix":"10.3390","volume":"18","author":[{"given":"Jan","family":"St\u0119pka","sequence":"first","affiliation":[{"name":"Doctoral School, Pozna\u0144 University of Medical Sciences, 60-812 Pozna\u0144, Poland"},{"name":"Department of Urology, Ministry of Internal Affairs Hospital, 61-701 Pozna\u0144, Poland"},{"name":"Department of Urology and Oncological Urology, Pozna\u0144 University of Medical Sciences, 61-701 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomasz","family":"Milecki","sequence":"additional","affiliation":[{"name":"Department of Urology and Oncological Urology, Pozna\u0144 University of Medical Sciences, 61-701 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u0119drzej","family":"Ksepka","sequence":"additional","affiliation":[{"name":"Students\u2019 Society of Urology, Pozna\u0144 University of Medical Sciences, 60-812 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7762-4012","authenticated-orcid":false,"given":"Anna","family":"Kujawska","sequence":"additional","affiliation":[{"name":"Department of Urology and Oncological Urology, Pozna\u0144 University of Medical Sciences, 61-701 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ja\u015bmina","family":"Hendrysiak","sequence":"additional","affiliation":[{"name":"Students\u2019 Society of Urology, Pozna\u0144 University of Medical Sciences, 60-812 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9257-6888","authenticated-orcid":false,"given":"Wojciech A.","family":"Cie\u015blikowski","sequence":"additional","affiliation":[{"name":"Department of Urology and Oncological Urology, Pozna\u0144 University of Medical Sciences, 61-701 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2864","DOI":"10.1007\/s00261-019-02023-1","article-title":"Extracapsular Extension on MRI Indicates a More Aggressive Cell Cycle Progression Genotype of Prostate Cancer","volume":"44","author":"Wibmer","year":"2019","journal-title":"Abdom.
