This study assessed the concordance of Gleason scores between MRI\u2013TRUS fusion biopsy and radical prostatectomy specimens, and identified clinical and histopathological factors associated with post-procedural Gleason score upgrading. Methods: This retrospective analysis involved patients who underwent transperineal MRI\u2013TRUS fusion biopsy followed by radical prostatectomy from 2020 to 2025. Concordance, upgrading, and downgrading of the Gleason score were assessed by comparing biopsy results with the final histopathological examination. Clinical parameters (age, PSA level, prostate volume, and PSA density) and histopathological features of biopsies (Gleason score and percentage of prostate lobes affected by cancer) were analyzed. Multivariate logistic regression models were stratified by PSA level (&lt;10 ng\/mL and &gt;10 ng\/mL). Results: Gleason score concordance was found in 53.1% of the 603 patients analyzed, upgrading in 29.9%, and downgrading in 17.1%. Higher Gleason scores on biopsy were independently associated with a lower risk of upgrading in the entire cohort and in both PSA subgroups. Larger tumor extent on biopsy was associated with a lower risk of upgrading, with heterogeneous dependencies between prostate lobes. The other clinical parameters showed no independent association with upgrading. Conclusions: Gleason score upgrading remains common after radical prostatectomy. The risk of this progression is primarily related to the histopathological features of the biopsy rather than to baseline clinical parameters, reflecting the limitations of biopsy as a sampling method and the biological heterogeneity of prostate cancer.<\/jats:p>","DOI":"10.3390\/jcm15072780","type":"journal-article","created":{"date-parts":[[2026,4,7]],"date-time":"2026-04-07T09:40:31Z","timestamp":1775554831000},"page":"2780","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Underestimation of Prostate Cancer Grade in Transperineal Fusion Biopsy and Its Predictive Factors: Correlation of Biopsy Findings with Post-Da Vinci Radical Prostatectomy Specimens"],"prefix":"10.3390","volume":"15","author":[{"given":"Hubert Andrzej","family":"Krzepkowski","sequence":"first","affiliation":[{"name":"Department of General, Oncological and Functional Urology, Military Institute of Medicine\u2014National Research Institute, 04-141 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Z\u0105bkowski","sequence":"additional","affiliation":[{"name":"Department of General, Oncological and Functional Urology, Military Institute of Medicine\u2014National Research Institute, 04-141 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4311-9995","authenticated-orcid":false,"given":"Maciej","family":"Wal\u0119dziak","sequence":"additional","affiliation":[{"name":"Department of General, Oncological, Metabolic and Thoracic Surgery, Military Institute of Medicine\u2014National Research Institute, Szaser\u00f3w 128 St., 04-141 Warsaw, Poland"},{"name":"Faculty of Medicine, University of Warsaw, 04-141 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8688-4171","authenticated-orcid":false,"given":"Tomasz Waldemar","family":"Kami\u0144ski","sequence":"additional","affiliation":[{"name":"VERSITI Blood Research Institute, 8727 W Watertown Plank Road, Wauwatosa, WI 53226, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hubert","family":"D\u0105browski","sequence":"additional","affiliation":[{"name":"Psychiatric Ward of the Mental Health Center in Kielce, 59 Kosuci\u0144skiego, 25-450 Kielce, Poland"},{"name":"\u015awi\u0119tokrzystkie Center of Psychiatry in Morawica, 5 Spacerowa, 26-026 Morawica, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Syry\u0142o","sequence":"additional","affiliation":[{"name":"Department of General, Oncological and Functional Urology, Military Institute of Medicine\u2014National Research Institute, 04-141 Warsaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,7]]},"reference":[{"key":"ref_1","first-page":"229","article-title":"Global Cancer Statistics 2022: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries","volume":"74","author":"Bray","year":"2024","journal-title":"CA Cancer J.
