Eur Urol Focus:根治性前列腺切除术中冷冻切片研究

2019-04-06 AlexYang MedSci原创

神经血管术(NVB)和神经血管术保留(NVBP)以及手术切缘状态是影响前列腺癌患者根治性切除术后功能和结果的主要术中影响因素。最近,有研究人员分析了NVBP术中执行冷冻切片技术(IFST)对NVB频率的影响以及对阳性手术切缘(PSMs)的影响。研究总共包括了346名患者。在这些患者中54.9%(n=190)经历了RP和IFST,45.1%的患者经历了RP而没有经历IFST。在NVBP期间进行了IF

神经血管术(NVB)和神经血管术保留(NVBP)以及手术切缘状态是影响前列腺癌患者根治性切除术后功能和结果的主要术中影响因素。最近,有研究人员分析了NVBP术中执行冷冻切片技术(IFST)对NVB频率的影响以及对阳性手术切缘(PSMs)的影响。

研究总共包括了346名患者。在这些患者中54.9%(n=190)经历了RP和IFST,45.1%的患者经历了RP而没有经历IFST。在NVBP期间进行了IFST后,研究发现,在整个群体中(pT2:14.6% vs 8.6%;pT3:47.1% vs 29.4%)PSM从29.5%减少到了15.4%(p=0.003)。相反地,在整个群体中(pT2:68.9% vs 99.0%; pT3:39.1% vs 88.2%)NVBP从55.3%增加到了95.5%(p<0.001)。在多变量逻辑回归分析中,在控制了患者和肿瘤特性后,IFST使用时PSMs的一个独立预测因子(风险比(OR):0.54,95%置信区间(CI):0.30-0.98; p=0.047),同时也是NVBP(OR: 5.60, 95% CI: 3.10-10.51; p<0.001)的一个独立预测因子。

最后,研究人员指出,与不进行IFST比较,在NVBP期间执行IFST能够导致NVBP频率变高,并且与更低的PSM相关。因此,研究人员最后建议在术中推荐进行IFST。

勃起功能障碍(ED)是根治性前列腺切除术的常见副作用,甚至在神经保留操作中也存在。为了减轻上述问题,被称为阴茎重建的计划已经开始进行。在上述问题中,最为常用的方法是在患者术后进行西地那非治疗或者PDE5抑制剂治疗。该方法基于一种理论,即这些药物可能能够增加阴茎氧化作用并提供抗凋亡因子(主要是NO和cGMP),从而保护阴茎组织在术后一段时期内神经功能减弱。预临床研究确认了西地那非在治疗ED中的作用,

前列腺是男性生殖器附属腺中最大的实质性器官。由前列腺组织和肌组织构成。前列腺癌是指发生在前列腺的上皮性恶性肿瘤。2004年WHO《泌尿系统及男性生殖器官肿瘤病理学和遗传学》中前列腺癌病理类型上包括腺癌(腺泡腺癌)、导管腺癌、尿路上皮癌、鳞状细胞癌、腺鳞癌。其中前列腺腺癌占95%以上,因此,通常我们所说的前列腺癌就是指前列腺腺癌。梅斯医学小编整理了近期前列腺疾病的研究进展,与大家一起分享学习!【
