摘要:
目的: 评估癌栓粘连静脉壁对肾细胞癌伴下腔静脉癌栓患者手术难度和预后的影响。方法: 对北京大学第三医院泌尿外科于2017年1月至2020年6月收治的94例非转移性肾细胞癌合并下腔静脉癌栓患者进行回顾性队列研究,收集患者的一般情况、临床病理特征、手术及生存信息。按术中发现癌栓粘连静脉壁为标准将患者分为两组,其中64例为癌栓粘连静脉壁组(deep invasive tumor thrombus, DITT), 30例为非粘连组(non-invasive tumor thrombus, NITT)。分别采用卡方检验、t检验和Mann-Whitney U检验进行两组间分类变量和连续变量的单因素比较,绘制Kaplan-Meier曲线并进行多变量Cox回归分析以评估癌栓粘连静脉壁对患者预后的影响。结果: 与NITT组相比,DITT组患者的手术难度明显增加,主要表现为手术时间更长(362.5 vs. 307.5 min,P=0.010),手术出血量更多(1 200 vs. 450 mL,P=0.006),围术期输血量更多(800 vs. 0 mL,P=0.021),血浆输注量更多(200 vs. 0 mL,P=0.001),开放手术占比更高(70.3% vs. 36.7%,P=0.002),术后住院时间更长(9.5 vs. 8.0 d,P=0.036),且发生术后并发症的比例更高(46.9% vs. 13.8%,P=0.002)。DITT与患者的总生存期更差呈正相关(P=0.022),即使在多因素分析中,DITT仍是影响肾细胞癌伴下腔静脉癌栓患者术后总生存率的不良预后因素[HR: 4.635 (1.017~21.116),P=0.047]。结论: 对于非转移性肾细胞癌合并下腔静脉癌栓的患者而言,癌栓粘连静脉壁会明显增加其手术难度,并与患者的不良预后相关。
