Patients were classified into a pre-mpMRI era (2007\u20132012) and a post-mpMRI era (2014\u20132019), excluding 2013 as a transition year. From 2014, standardized 3T mpMRI interpreted by a single uroradiologist was systematically integrated into side-specific surgical planning, including nerve-sparing decisions. The primary endpoint was any positive surgical margin (PSM); the secondary endpoint was biochemical recurrence (BCR, prostate-specific antigen (PSA)\u2009\u2a7e\u20090.2\u2009ng\/mL) within 24\u2009months. Logistic regression (overall and stratified by pT2\/pT3) assessed associations between era and PSM, with multivariable adjustment for age, PSA, tumor volume, biopsy Gleason score, D\u2019Amico risk group, and pathological stage. BCR-free survival was analyzed with Kaplan\u2013Meier curves, log-rank tests, and Cox models censored at 24\u2009months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Of 844 men, 393 were operated on in 2007\u20132012 and 451 in 2014\u20132019. Compared with the pre-mpMRI era, patients in the mpMRI era were older (median 67 vs 64\u2009years) and had larger tumor volume (3.6 vs 2.2\u2009cc) and less favorable Gleason and D\u2019Amico profiles, while pT distribution was similar. Margin status was available for 802 patients; PSM decreased from 25% (97\/381) to 15% (65\/421) in the mpMRI era (absolute reduction ~10 percentage points). In the overall cohort, surgery in the mpMRI era was associated with lower odds of PSM (adjusted odds ratio 0.51; 95% CI 0.34\u20130.74;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.001). In pT2 disease, the association was directionally favorable but non-significant (adjusted odds ratio (OR) 0.71; 95% CI 0.42\u20131.17;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.20), whereas in pT3 tumors the mpMRI era was associated with a marked reduction in PSM (adjusted OR 0.35; 95% CI 0.19\u20130.63;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.001). Among 807 patients with PSA follow-up, 24-month BCR-free survival was 0.896 (95% CI 0.861\u20130.923) in 2007\u20132012 and 0.846 (95% CI 0.801\u20130.881) in 2014\u20132019 (log-rank\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.0377); the corresponding unadjusted hazard ratio for BCR was 1.55 (95% CI 1.02\u20132.35), which attenuated and lost significance after adjustment for age and D\u2019Amico risk (adjusted hazard ratio 1.10;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.656).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In a high-volume center with a stable, experienced robotic surgeon, the preoperative mpMRI era has been linked to better surgical outcomes, particularly for patients with more pT3 disease. While this temporal association supports a potential contribution of systematic preoperative mpMRI to surgical precision, residual temporal confounding cannot be excluded. Early BCR-free survival within 24\u2009months did not differ significantly between eras after adjustment for baseline risk. In the future, more precise 3D MRI mapping could further enhance the preservation of neurovascular bundles without compromising the oncological prognosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Trial registration:<\/jats:title>\n                    <jats:p>Not applicable (retrospective analysis of routinely collected clinical data).<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17562872261452717","type":"journal-article","created":{"date-parts":[[2026,6,5]],"date-time":"2026-06-05T07:02:31Z","timestamp":1780642951000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Impact of preoperative MRI on surgical outcomes of robot-assisted laparoscopic prostatectomy: a single-center retrospective cohort of 844 patients"],"prefix":"10.1177","volume":"18","author":[{"given":"Charles Henry","family":"Rochat","sequence":"first","affiliation":[{"name":"Clinique G\u00e9n\u00e9rale Beaulieu, Geneva 1206, Switzerland"},{"name":"Swiss International Prostate Center, Geneva, Switzerland"},{"name":"Geneva Foundation for Medical Education and Research, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Schaffar","sequence":"additional","affiliation":[{"name":"Swiss International Prostate Center, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-2368-7634","authenticated-orcid":false,"given":"Jacques Martin","family":"Randriantsalama","sequence":"additional","affiliation":[{"name":"Geneva Foundation for Medical Education and Research, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ildiko Quinodoz","family":"Szalay","sequence":"additional","affiliation":[{"name":"Swiss International Prostate Center, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georges Antoine","family":"de Boccard","sequence":"additional","affiliation":[{"name":"Clinique G\u00e9n\u00e9rale Beaulieu, Geneva, Switzerland"},{"name":"Swiss International Prostate Center, Geneva, Switzerland"},{"name":"Geneva Foundation for Medical Education and Research, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martina Martins","family":"Favre","sequence":"additional","affiliation":[{"name":"Swiss International Prostate Center, Geneva, Switzerland"},{"name":"Imagerive, Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,5]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21834"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.juro.2012.01.061"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11701-011-0266-7"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clgc.2017.06.001"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.3390\/cancers14163966"},{"issue":"1095","key":"e_1_3_4_7_2","article-title":"Accuracy of multiparametric magnetic resonance imaging in predicting extracapsular extension of prostate cancer: a systematic review and meta-analysis","volume":"92","author":"Zhang F","year":"2019","unstructured":"Zhang F, Yang XJ, Fan Y, et al.
