| 1 | Overall rate, location, and predictive factors for positive surgical margins after robot-assisted laparoscopic radical prostatectomy for high-risk prostate cancer显示文摘我们与高风险的前列腺癌症在 271 个病人报导全面的率,地点和积极外科的边缘(PSM ) 的预兆的因素。在 2008 年 4 月和 2011 年 10 月之间,我们有希望地从作为 D'Amico 分类的病人收集了数据高风险经历了帮助机器人的 laparoscopic 激进分子前列腺切除术。PSM 的全面的率和地点被报导。逐步的逻辑回归模型被适合估计 PSM 的预兆的因素。PSM 的全面的率是 25.1%(271 个病人中的 68 个) 。这些 PSM,(68 中的 26 个)38.2% 是 posterolateral (PL ) , 26.5%(68 中的 18 个) multifocal, 16.2%(68 中的 11 个) 在顶, 14.7%(68 中的 10 个) 在膀胱颈,并且 4.4%(3/68 ) 在另外的地点。有病理学的阶段 pT2 的病人的 PSM 率是 8.6%(140 中的 12 个) , 26.6%(64 中的 17 个) pT3a, 53.3%(32/60 ) pT4 的 pT3b,和 100%(7 中的 7 个) 。在包括 pre- , intra- ,和手术后的参数的一个逻辑回归模型,身体团索引(机会比率[或] :1.09;95% 信心间隔[CI ] :1.01-1.19, P= 0.029 ) ,病理学的舞台(pT3b 或更高对 pT2;或:5.14;95% CI:1.92-13.78;P = 0.001 ) 并且肿瘤的百分比(或:46.71;95% CI:6.37-342.57;P < 0.001 ) 是为 PSM 的独立预兆的因素。在病人在的 PSM 的最普通的地点高风险是 PL 方面,它反映报导肿瘤攻击性。PSM 的唯一的重要预兆的因素是病理学的结果,例如在标本和病理学的舞台的肿瘤的百分比。 | Sung Gu Kang Oscar Schatloff Abdul Muhsin Haidar Srinivas Samavedi Kenneth J Palmer Jun Cheon Vipul R Patel | 2016 | Asian Journal of Andrology2016，18，1： | 9 |
| 2 | Magnetic resonance imaging-guided prostate biopsydA review of literature显示文摘Objective:Multiparametric magnetic resonance imaging(MP-MRI)helps to identify lesion of prostate with reasonable accuracy.We aim to describe the various uses of MP-MRI for prostate biopsy comparing different techniques of MP-MRI guided biopsy.Materials and methods:A literature search was performed for“multiparametric MRI”,“MRI fusion biopsy”,“MRI guided biopsy”,“prostate biopsy”,“MRI cognitive biopsy”,“MRI fusion biopsy systems”,“prostate biopsy”and“cost analysis”.The search operation was performed using the operator“OR”and“AND”with the above key words.All relevant systematic reviews,original articles,case series,and case reports were selected for this review.Results:The sensitivity of MRI targeted biopsy(MRI-TB)is between 91%e93%,and the specificity is between 36%e41%in various studies.It also has a high negative predictive value(NPV)of 89%e92%and a positive predictive value(PPV)of 51%e52%.The yield of MRI fusion biopsy(MRI-FB)is similar,if not superior to MR cognitive biopsy.In-bore MRI-TB had better detection rates compared to MR cognitive biopsy,but were similar to MR fusion biopsy.Conclusions:The use of MRI guidance in prostate biopsy is inevitable,subject to availability,cost,and experience.Any one of the three modalities(i.e.MRI cognitive,MRI fusion and MRI in-bore approach)can be used.MRI-FB has a fine balance with regards to accuracy,practicality and affordability. | Kulthe Ramesh Seetharam Bhat Srinivas Samavedi Marcio Covas Moschovas Fikret Fatih Onol Shannon Roof Travis Rogers Vipul R.Patel Ananthakrishnan Sivaraman | 2021 | Asian Journal of Urology2021，8，1： | 3 |
