e15145 Background: The risk of biological recurrence following radical prostatectomy depends, among other factors, on surgical margins status. This study compared the prognosis of prostate cancer patients with positive surgical margins according to the predominant Gleason pattern (PrdGP). Methods: Prospective study of 247 consecutive prostate cancer patients, who underwent radical prostatectomy (RP) from 3/2007 to 12/2009, and were followed up in our institution. Pathological stage and Gleason score were determined in RP specimens by a pathological reference. Biological recurrence was defined as two consecutive values of PSA > 0.2 ng/mL. The median overall follow-up was 33 months (2 to 54 months). Biological recurrence-free survival was estimated and compared using Kaplan-Meier plots and Log rank test. A multivariate logistic regression model was done with PrdGP4, and two other predictive variables (pT≥3a, preoperative PSA level) entered as statistically significant independent predictors of biological recurrence. Results: Forty-eight patients (19.4%) had a positive surgical margins, 26 patients have PrdGP3 (54%) and 22 have PrdGP4 (46%). Whereas 7 biological recurrences were observed in PrdGP4 patients, none occurred in PrdGP3 patients. Biological recurrence-free survivals were significantly different (Log rank p=0.001). In multivariate analysis, PrdGP4 was a predictor of biological recurrence (p<0.0001, OR= 9.023, 95% CI [3.161–25.757]). Conclusions: This study demonstrates that biological recurrence after positive surgical margin are correlated with the predominant Gleason pattern assessed on radical prostatectomy specimen which s more easily evaluable than accurate margins features. Adjuvant treatment, specifically external beam radiotherapy, should be indicated in accordance to this result. [Table: see text]

IntroductionPositive surgical margins (PSM) in cancer patients are commonly associated with worse prognosis and a higher risk of secondary treatment. However, the relevance of this parameter in prostate cancer patients undergoing radical prostatectomy (RP) remains controversial, given the inconsistencies in its ability to predict biochemical recurrence (BCR) and oncological outcomes. Hence, further assessment of the utility of surgical margins for prostate cancer prognosis is required to predict these outcomes more accurately. Over the last decade, studies have used the Gleason score (GS) of positive margins to predict outcomes. Herein, the authors aim to conduct a systematic review investigating the role of GS of PSM after radical prostatectomy in predicting BCR and oncological outcomes.Methods and analysisWe will perform a search using MEDLINE, EMBASE, SCOPUS and COCHRANE databases. The review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We will screen titles and abstracts to select articles appropriate for full-text review. Studies discussing GS of PSM after RP will be included. Given the change in reporting of GS, only articles from 2005 to 2019 will be included. The quality of the studies chosen will be assessed using the Newcastle Ottawa tool for non-randomised and Cochrane risk of bias for randomised control studies. We will adopt the grading of recommendations, assessment, development and evaluation framework to comment on quality of cumulative evidence. The primary outcome measure will be time to BCR. Secondary outcome measures include secondary treatment, disease-specific survival, disease progression-free and overall mortality at follow-up period. We aim to perform a meta-analysis if the level of heterogeneity is acceptable (I2<50%).Ethics and disseminationThe review does not require ethics approval as it is a review of published literature. The findings of the review will be submitted for peer-reviewed publications and presented at scientific meetings.PROSPERO registration numberCRD42019131800.

Abstract Background Patients with advanced high-risk prostate cancer (PCa) are prone to have worse pathological diagnoses of positive surgical margins and/or lymph node invasion, resulting in early biochemical recurrence (BCR) despite having undergone radical prostatectomy (RP). Therefore, it is controversial whether patients with high-risk PCa should undergo RP. The purpose of this study was to evaluate the efficacy of neoadjuvant chemohormonal therapy (NAC) followed by “extended” RP. Methods A total of 87 patients with high-risk PCa prospectively underwent extended RP after NAC; most of the patients underwent 6 months of estramustine phosphate (EMP) 140 mg twice daily, along with a luteinizing hormone-releasing hormone agonist/antagonist. We developed our surgical technique to reduce the rate of positive surgical margins. We aimed to approach the muscle layer of the rectum by dissecting the mesorectal fascia and continuing the dissection through the mesorectum until the muscle layer of the rectum was exposed. Results More than 1 year had elapsed after surgery in all 86 patients, with a median follow-up period of 37.7 months. The 3-year BCR-free survival was 74.9%. Multivariate Cox-regression analysis revealed that a positive core ratio of 50% or greater and pathological stage of pT3 or greater were independent predictors for BCR. About 17 of 23 cases received salvage androgen deprivation therapy and concurrent external beam radiotherapy, and showed no progression after the salvage therapies. Conclusions NAC concordant with extended RP is feasible and might provide good cancer control for patients with high-risk PCa.

113 Background: Follow up after radical prostatectomy should be tailored to clinical and pathologic characteristics. To determine predictive factors for early, intermediate and late biochemical recurrence (BCR) after minimally invasive radical prostatectomy (MIRP: lap and robot) in patients with localized prostate cancer (PCa). Methods: Prospective clinical, pathologic, and outcome data were collected for 6195 patients with cT1-3N0M0 PCa treated with MIRP at our institution from 2000 to 2016. None of them received neoadjuvant therapy. BCR was defined as PSA level greater than 0.2 ng/ml. Time to BCR was divided in terciles to identify variables associated with early ( < 12 months), intermediate (12-36 months) and late BCR ( > 36 months). Comparisons among groups were performed using ANOVA or Chi square test. Logistic regression models were built to determine risk factors associated with BCR at each time interval. Results: We identified 1148 (19%) patients with BCR. Median time to BCR was 24 months. Statistically significant differences were found between the groups concerning PSA preoperative, D’Amico risk, type of surgery, pT stage, pathological Gleason, positive margins and extracapsular extension. Multivariable logistic regression analysis showed preoperative PSA, positive nodes, positive surgical margins and laparoscopic surgery were associated with early BCR. Laparoscopic surgery was the only risk factor associated with intermediate term BCR. Significant predictors of late BCR included Gleason ≥ 7, ≥ pT3, positive surgical margins, lymph node dissection performance and laparoscopic surgery. Conclusions: Patients with high risk features like Gleason ≥ 7, ≥ pT3 and or positive surgical margins may develop late recurrence and deserve long term follow up. Identify patients with higher PSA and lymph node invasion has an important predictive role due to the risk of BCR within the first year. The association between laparoscopic technique and late BCR deserves further evaluation.
