Abstract:
Objective:To investigate the influencing factors of pathological positive surgical margins(PSM)after radical resec-tion of prostate cancer.Methods:The clinical data of 407 patients who underwent radical resection of prostate cancer in our hospital from 2011 to 2020 were retrospectively analyzed.And the patients were divided into two groups according to postoperative pathological results.Single factor analysis was used to evaluate the differences in postoperative Gleason score,preoperative total prostate-specific antigen(tPSA),preoperative serum free prostate-specific antigen to preoperative tPSA ratio(fPSA/tPSA),clinical stage,postopera-tive pathological stage,operation method,age,body mass index(BMI),diameter and volume of prostate tumor.Multivariate logistic regression was used to determine the independent risk factor of PSM.Results:Among 407 patients with prostate cancer,179 cases(43.98％)were positive.Univariate analysis showed that there were significant differences in postoperative Gleason score,preopera-tive tPSA,clinical stage and postoperative pathological stage between the two groups(P＜0.05).And Gleason score,preoperative tPSA and pathologic stage were independent risk factors for PSM.Conclusion:There are relationships between PSM and post opera-tive Gleason score,tPSA,clinical T stage,postoperative pathologic pT stage.Among them,postoperative Gleason score(Gleason=7 points,Gleason≥8 points),preoperative total prostate-specific antigen(tPSA＞20 μg/L),and postoperative pathologic pT stage(pT3a,pT3b)were independent risk factors for positive pathological margins of prostate cancer.
