在获得关于其对生存率影响的高质量证据之前,微创手术已经是早期宫颈癌根治性子宫切除术(opensurgery)的替代方法。我们试图确定微创手术对宫颈癌根治性子宫切除术妇女全因死亡率的影响。
METHODS方法

我医院委员会进行了一项队列研究,研究对象是-年期间因IA2或IB1期宫颈癌而接受根治性子宫切除术的妇女。研究采用了治疗倾向评分加权的逆概率。我们还使用监测、流行病学和最终结果程序数据库,对间断性地-年期间因宫颈癌接受根治性子宫切除术的妇女进行了分析。
RESULTS结果

在初步分析中,名女性中有人(49.8%)接受了微创手术。接受微创手术治疗的女性通常都是白人,有私人保险,有较高的社会经济地位,有较小的、较低级别的肿瘤,而且在研究期间比接受开放式手术的女性更可能晚得到诊断。
Overamedianfollow-upof45months,the4-yearmortalitywas9.1%amongwomenwhounderwentminimallyinvasivesurgeryand5.3%amongthosewhounderwentopensurgery(hazardratio,1.65;95%confidenceinterval[CI],1.22to2.22;P=0.bythelog-ranktest).
在45个月的中位随访中,接受微创手术的妇女4年死亡率为9.1%,接受开放式手术的妇女死亡率为5.3%(危险比为1.65;95%置信区间[CI],1.22~2.22;通过log-rank检验的P=0.)。

在采用微创根治性子宫切除术之前(即,在-年期间),接受子宫癌根治性子宫切除术的妇女4年相对生存率保持稳定(年百分比变化0.3%;95%可信区间,0.1?0.6)。采用微创手术的同时,年以后4年相对生存率下降0.8%(95%CI,0.3~1.4)(趋势变化P=0.01)。

在一项流行病学研究中,在患有IA2或IB1宫颈癌的女性中,微创根治性子宫切除术的总生存期短于开放性手术。(由美国国家癌症研究所和其他机构资助)
