中文摘要:
      目的:分析前列腺癌根治术后病理得分较穿刺得分增加的原因,并建立一个可以预测中国人群中前列腺癌根治术后病理升 级的模型。方法:以2008 年8 月至2013 年12 月在我院泌尿科行前列腺癌根治性切除术的264例患者的临床资料为基础,根据 术前和术后患者病理得分的变化将其分为升级组和未升级组。运用单因素和多因素logistic 回归分析病理升级的原因,并通过多 因素回归系数建立预测病理升级的诺模图。结果:264 例患者中,共238 例最终纳入统计分析,多因素logistic 回归分析显示前列 腺特异抗原密度(0R=3.854,P=0.001 )和穿刺Gleason(≤ 6)评分是中国人群中前列腺癌根治术后病理升级的独立危险因素。前列腺 特异抗原密度和穿刺得分的ROC 最佳截断取值为0.37 ng/ml 2和8 分。运用上述两个变量建立了一个可用于预测病理升级的诺 模图。结论:前列腺特异抗原密度和穿刺Gleason 评分是预测中国人群中前列腺癌根治术后病理升级的独立危险因素,本研究所 得的诺模图可以很好地预测前列腺癌根治术后的病理升级。
英文摘要:
      Objective:To analyze the reason of upgrade in Gleason score between initial prostate biopsy and final radical prostatectomy specimens and develop a nomogram to predict the probability of pathological upgrade.Methods:From August 2008 to December 2013, a total of 264 prostate cancer patients underwent RP in our department were selected and divided into two groups according to the upgrade of biopsy and final pathology GS. Both a univariate analysis and a Forward conditional multivariate logistic regression model (LRM) analysis were performed to identify the risk factor (s) of pathological upgrade. A nomogram predicting the probability of pathological upgrade was established by using LRM regression coefficients.Results:In total, 238 of the 264 patients were analyzed. Multivariate logistic regression analysis showed that higher prostate specific antigen density(PSAD) (0R=3.854, P=0.001) and low grade (≤ 6) biopsy GS were. The dependent risk factors of the pathological upgrade after radical prostatectomy. The optimal cutoff value of PASD and biopsy score were 0.37 ng/ml 2 and 8 points. A nomogram combining aforementioned two variables to predict pathological upgrading was established.Conclusion:PASD and biopsy Gleason score were independent risk factors for predicting the postoperative pathological upgrade in Chinese population, the nomogram established in the study could well predict the pathological upgrade.
