目的:建立预测前列腺癌术后切缘阳性结果的列线图模型,并进行相应的验证,为预测术后切缘阳性的风险提供依据。方法:纳入PC-follow数据库中北京医院、北京大学第一医院、北京大学第三医院、海军军医大学第一附属医院、西安交通大学第一附属医院2015—2018年收治的2215例前列腺癌患者的病例资料,年龄67.3(33~88)岁。PSA(45.2±18.9)ng/ml。前列腺穿刺活检针数6~32针,穿刺阳性针数百分比4%~100%,穿刺活检病理Gleason评分6~10分。采用单纯随机抽样法将患者分为建模组和验证组。建模组1770例,年龄65.5(33~88)岁,PSA(48.2±12.4)(0.01~99.4)ng/ml。验证组445例,年龄68.6(47~82)岁,PSA(43.7±14.8)(0.01~87.2)ng/ml。对两组患者年龄(<60岁,60~70岁,>70岁)、PSA(<4 ng/ml,4~10 ng/ml,11~20 ng/ml,>20 ng/ml)、盆腔MRI检查结果(阴性,可疑,阳性)、肿瘤临床分期(T 1~T 2期,≥T 3期)、穿刺阳性针数百分比(≤33%,34%~66%,>66%)、穿刺活检病理Gleason评分(≤6分,7分,≥8分)进行单因素和多因素logistic分析,筛选有意义的指标构建预测前列腺癌术后切缘阳性结果的列线图模型。在验证组对该模型进行验证,并与构成列线图的单一因素的预测效果进行比较。结果:单因素分析结果显示,术前PSA水平、盆腔MRI检查结果、穿刺针数阳性率、穿刺病理Gleason评分与术后切缘阳性率有相关性(P<0.05)。多因素分析结果显示,术前PSA水平(OR=2.046,95%CI 1.022~4.251,P=0.009)、穿刺阳性针数百分比(OR=1.502,95%CI 1.136~1.978,P=0.002)、穿刺病理Gleason评分(OR=1.568,95%CI 1.063~2.313,P=0.028)、盆腔MRI检查结果(OR=1.525,95%CI 1.160~2.005,P=0.033)为前列腺癌术后切缘阳性的独立预测指标,根据上述指标建立列线图模型。列线图模型预测验证组切缘阳性的受试者工作特征曲线(ROC)的曲线下面积为0.776,而以术前PSA水平、穿刺阳性针数百分比、穿刺病理Gleason评分、盆腔MRI检查结果、术后病理Gleason评分等单一因素预测验证组切缘阳性的ROC曲线下面积分别为0.554、0.615、0.556、0.522和0.560,列线图模型与单一指标比较差异均有统计学意义(P<0.05)。结论:构建的列线图模型较单独应用术前PSA水平、穿刺阳性针数百分比、穿刺病理Gleason评分、盆腔MRI检查结果、术后病理Gleason评分在预测前列腺癌术后切缘阳性方面具有更高的诊断价值。 相似文献

PURPOSE: Pretreatment clinical staging of prostatic adenocarcinoma is important due to the increasing use of nonsurgical treatment options. Using multivariate analysis we assessed the predictive value of biopsy cores positive for cancer as a percent of all cores obtained as well as the percent surface area of needle cores involved with tumor for determining tumor volume and pathological stage at radical prostatectomy. Candidate variables for the multivariate model included patient age, clinical disease stage, serum prostate specific antigen (PSA) and Gleason score of cancer in the needle biopsy. MATERIALS AND METHODS: We reviewed prostate needle biopsy findings in 207 consecutive patients who subsequently underwent radical retropubic prostatectomy. Each biopsy specimen was assessed for tumor involvement by calculating the percent of cores positive for cancer, percent surface area involved in all cores and Gleason score. Initial serum PSA and preoperative clinical disease stage were incorporated with biopsy results into a multivariate model to determine the parameters most predictive of pathological stage and tumor volume at radical retropubic prostatectomy. RESULTS: Of the 207 patients 152 (73.4%) had organ confined cancer and 55 (26.6%) had extraprostatic extension (pathological stages T2 and T3 or greater, respectively). Preoperative clinical staging information was available in 195 cases, in which disease was clinically confined and not confined in 184 (94.4%) and 11 (5.6%), respectively. Needle biopsy revealed a surface area of cancer ranging from less than 5% in 69 patients (33.3%) to 90% (mean 16, median 10). Univariate analysis demonstrated that the risk of extraprostatic extension was predicted by preoperative serum PSA (p = 0.027), the percent of cores and percent of surface area positive for cancer (p <0.0001), and Gleason score (p = 0.0009). Clinical stage approached significance (p = 0.071). Multivariate analysis showed that the percent of positive cores (p = 0.0003), initial serum PSA (p = 0.005) and Gleason score of cancer in the needle biopsy (p = 0.03) were the only parameters that jointly predicted pathological stage (T2 versus T3). Percent of tumor surface area involvement in the needle biopsies did not add any more information after the percent of positive cores was known. Univariate analysis revealed that the percent of cores positive for cancer (Spearman r = 0.52, p <0.0001), Gleason score (Spearman r = 0.34, p <0.0001) and initial serum PSA (Spearman r = 0.24, p = 0.003) were predictive of log tumor volume at radical prostatectomy, while clinical stage was not (rank sum test p = 0.14). On multivariate analysis the percent of positive cores (p <0.0001), Gleason score (p <0.0001) and initial serum PSA (0.0033) were the only variables that jointly were predictive of tumor volume. CONCLUSIONS: The percent of needle biopsy cores and surface area positive for cancer are the strongest predictors of pathological stage and tumor volume on multivariate analysis incorporating preoperative serum PSA and Gleason score. 相似文献

PURPOSE: We addressed whether Gleason score 3 + 4 = 7 and 4 + 3 = 7 cancers on needle biopsy behave differently and whether this behavior is independent of the number of cores involved by cancer. If it is not an independent predictor of prognosis, one may report Gleason score 7 cancer with the number of positive cores without regard to whether the primary pattern was 3 or 4. This practice would remove a source of poor interobserver reproducibility when grading prostate cancer on needle biopsy. MATERIALS AND METHODS: We identified 537 patients with Gleason score 7 tumors on biopsy. The results of patient preoperative digital rectal examination, serum prostate specific antigen (PSA) measurement and age were used to predict 4 outcomes based on assessment of the corresponding radical prostatectomy specimens, including 1) pathological stage (organ confined, focal extraprostatic extension, nonfocal extraprostatic extension or seminal vesicle-lymph node involvement), 2) organ confinement (yes/no), 3) Gleason score and 4) surgical margin status (positive/negative) RESULTS: Multivariate regression of postoperative Gleason score groups against all 5 input variables (3 + 4 versus 4 + 3, number of positive cores, PSA, age and digital rectal examination) yielded a statistically significant positive correlation with preoperative PSA (p <0.001) and preoperative Gleason scores of 4 + 3 versus 3 + 4 on biopsy (p <0.001). Pathological stage correlated with preoperative PSA (p <0.001), Gleason score 4 + 3 disease (p = 0.016), positive digital rectal examination (p <0.001) and 3 or more positive cores (p = 0.016). Positive surgical margins were predicted only by preoperative PSA (p = 0.001). CONCLUSIONS: Because the biological behavior of biopsy Gleason score 3 + 4 or 4 + 3 of Gleason score 7 cancer differs regardless of the number of cores involved, future nomograms predicting pathological stage would benefit from examining 3 + 4 and 4 + 3 disease separately. 相似文献

Objectives To compare positive surgical margins in both radical retropubic prostatectomies and laparoscopic surgery in two reference
centres in Brazil.
Materials and methods One hundred and seventy nine pathological studies from patients, who underwent radical prostatectomy due to prostate adenocarcinoma,
89 submitted to retropubic surgery and 90 to laparoscopic surgery, were analyzed. Inclusion criteria
Patients with PSA ≤15 ng/ml, and a Gleason score ≤7 at the prostate biopsy, maximum T2 clinical staging.
Results There has been surgical margin compromising in 41.57% of the patients submitted to retropubic radical prostatectomy (RRP),
34.21% of which were at pT2 stage and 84.61% were at pT3 stage. In patients submitted to laparoscopic radical prostatectomy
(LRP) positive surgical margin was found at 24.44% of the cases: 20.98% of which were at pT2 stage and 55.55% at pT3 stage.
Conclusions In the analyzed samples, proportion of positive surgical margin was higher in RRP than in LRP (P = 0.023). A higher number of patients on a randomized prospective study would be necessary for a better comparison between
the groups. 相似文献

OBJECTIVES: To analyze the association between Gleason score, stage and status of surgical margins with tumor volume in prostate cancer progression after radical prostatectomy. METHODS: 200 consecutive radical prostatectomy specimens were analyzed. Preoperative clinical stage, PSA, results of prostate biopsies as well as pathological results were noted. A biochemical recurrence was defined as a single, postoperative detectable PSA level (>0.2 ng/ml). Tumor volume was compared to postoperative staging, Gleason score, and surgical margin status to predict tumor progression. Univariate and multivariate analysis using stepwise logistic regression were used to identify parameters with additional prognostic value. RESULTS: Pathological results of the prostatectomy specimens showed 149 (74.5%) pT2a-b, 29 (14.5%) pT3a and 22 (11%) pT3b tumors. Tumor volume was 0.57 cc for pT2a, 1.2cc for pT2b, 1.7cc for pT3a and 2.9cc for pT3b, respectively (p<0.05). Taken together, mean volume for pT2 and pT3 were 1.06 and 2.2 cc, respectively (p<0.0001). Five-year progression-free actuarial survival was 69.7%. Using univariate analysis, tumor progression correlated with final Gleason score (p<0.0007), positive surgical margins (p=0.02), tumor volume (p=0.009) and stage (p<0.0001). In a multivariate analysis, tumor progression correlated only with the final Gleason score (p=0.04) and stage (p=0.0002). CONCLUSION: Gleason score and pathological stage are independent factors to predict prostate cancer progression after radical prostatectomy. When these parameters are known, tumor volume does not provide additional information. 相似文献
