PATIENTS AND METHODS: Prospective data on 183 consecutive LRP patients with pT2 disease, operated on by a single surgeon (2003-2009), were studied. Outcomes were grouped as pre-, peri-, and post-operative and included: age, ethnicity, Gleason score, reporting pathologist, percentage of positive cores, operative time, blood loss, nerve-sparing status, hospital stay and prostate weight. Descriptive analysis and logistic regression analysis were carried out to compare these variables by positive margin status. RESULTS: A total of 30 (16.4 %) positive surgical margins (PSMs) were reported. Surgical stage, earlier date of surgery, and lower prostatic weight showed statistically significant associations with PSM status in both univariate and multivariate analysis. The reporting pathologist was not found to be predictive of PSMs (P = 0.855). CONCLUSION: We showed that the reporting pathologist does not influence T2 positive margin status, in contrast to tumour characteristics and surgeon experience. T2 positive margin assessment therefore appears to be an objective quality outcome measure. date: 2017-01-01 date_type: published official_url: http://doi.org/10.1007/s00345-016-1836-0 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: JOURNAL ARTICLE verified: verified_manual elements_id: 1132934 doi: 10.1007/s00345-016-1836-0 pii: 10.1007/s00345-016-1836-0 lyricists_name: Wulaningsih, Wahyu lyricists_id: WULAN33 full_text_status: public publication: World Journal of Urology volume: 35 number: 1 pagerange: 35-43 issn: 1433-8726 citation: Damani, A; Van Hemelrijck, M; Wulaningsih, W; Crawley, D; Cahill, D; (2017) Are you now a good surgeon?
