不同的手术技术可以减少手术期间肿瘤细胞向血液中的传播。本项研究旨在比较手术中不同血管结扎序列对肿瘤细胞扩散和非小细胞肺癌患者生存的影响。

背景及目的:
不同的手术技术可以减少手术期间肿瘤细胞向血液中的传播。本项研究旨在比较手术中不同血管结扎序列对肿瘤细胞扩散和非小细胞肺癌患者生存的影响。

方法:
这是一项多中心随机临床试验,开始于2016年12月结束于2018年3月,所有患者均为接受胸腔镜肺叶切除术的非小细胞肺癌患者。不同干预措施的分组为:首先结扎静脉组与首先结扎动脉组。主要观察结果为手术后叶酸受体阳性循环肿瘤细胞(FR + CTC)和5年总体,无疾病和肺癌特异性存活率的变化。

结果:
共有86人被随机分组,对其中78名患者进行了分析。手术后,相比于结扎静脉组38例中有12例(31.6%),结扎动脉组40例患者中有26例(65.0%)观察到FR + CTC 的增量变化,(P= .003)。多变量分析证实,首先结扎动脉是手术中FR + CTC增加的危险因素(风险比[HR],4.03 [95%CI,1.53-10.63]; P= .005)。倾向性匹配分析包括420名患者(210名患者采用静脉结扎手术,210名采用动脉结扎)。首先结扎静脉组的结果显着优于首先结扎动脉组5年总生存率(73.6%[95%CI,64.4%-82.8%] vs 57.6%[95%CI,48.4%-66.8%]; P= .002),无病生存率(63.6%[95%CI,55.4%-73.8%]对48.4%[95%CI,40.0%-56.8%]; P= .001)和肺癌特异性生存率(76.4%[95%CI,67.6%-85.2%] vs 59.9%[95%CI,50.5%-69.3%]; P= .002)也明显较好。

结论:
在手术期间首先结扎出血静脉可以减少肿瘤细胞的传播,并改善非小细胞肺癌患者的生存结果。
