NEJM:选择性颈清扫术更适合治疗早期口腔鳞状细胞癌

2015-06-01 崔倩 译 MedSci原创

背景:早期口腔癌患者在节点复发后初次手术时应用选择性颈清扫术还是治疗性颈清扫术进行治疗的问题是一直存在争论的。      方法:在这项前瞻性、随机对照试验中,研究人员评估了单侧阶段T1或T2口腔鳞状细胞癌患者使用选择性淋巴结清扫术(在初次手术时同侧颈淋巴清扫术)和治疗淋巴结清扫术(观察等待之后进行淋巴结复发的颈淋巴结清扫术)对生存的影响。主要和次要终点分别是

背景:早期口腔癌患者在节点复发后初次手术时应用选择性颈清扫术还是治疗性颈清扫术进行治疗的问题是一直存在争论的。  
    
方法:在这项前瞻性、随机对照试验中,研究人员评估了单侧阶段T1或T2口腔鳞状细胞癌患者使用选择性淋巴结清扫术(在初次手术时同侧颈淋巴清扫术)和治疗淋巴结清扫术(观察等待之后进行淋巴结复发的颈淋巴结清扫术)对生存的影响。主要和次要终点分别是总生存率和无病生存率。
    
结果:从2004年到2014年,共有596名患者参加此项研究。根据预先设定的数据安全监测委员会,该报告前500名患者的总结果(治疗手术组255人,选择性手术组245人),中位随访39个月。选择性手术组有81例复发,50例死亡。治疗手术组有146例复发,79例死亡。治疗3年后,与治疗性颈清扫术的总生存率(67.5%;95%Cl,61.0-73.9)相比,选择性颈清扫术整体生存率有所改善(80.0%;95%的置信区间[Cl],74.1-85.8),选择性颈清扫术组的死亡危险比为0.64(95%Cl,0.45-0.92;数秩检验P=0.01)。当时,选择性颈清扫术组患者的无病生存率也比治疗性颈清扫术组的要高(69.5% vs 45.9%,P<0.001)。选择手术组在所有亚组中没有显著的相互作用。选择手术组和治疗手术组的不良事件发生率分别为6.6%和3.6%。
    
结论:对于早期口腔鳞状细胞癌患者,选择性颈淋巴清扫术的整体和无病生存率都要高于治疗性颈淋巴结清扫术。
