2018年1月,发表在《BMJ》上的一项准实验研究,考察了新辅助化疗(NACT)对晚期卵巢癌全因死亡率的影响。

目的:评估NACT的增加使用对晚期上皮性卵巢癌全因死亡率的因果效应效应。

设计:准实验模糊回归不连续设计和横断面分析。

建立:由癌症协会批准的美国癌症项目。

受试者:2011至2012年间NACT使用快速增加区域(新英格兰和东南部中部地区增加27%)或保持不变区域(控制地区,南大西洋,西北中部,东北中部)被诊断为上皮性卵巢癌3C或4阶段的6034名妇女。

主要结局:3年内全因死亡率的诊断。采用Kaplan-Meier曲线和比例风险模型评估比较快速使用区域和控制区域之间的死亡率差异。

结果:2011和2012年间,两个快速使用区域共有1156名晚期上皮性卵巢癌女性接受治疗,3个对照区域有4878名女性接受治疗。在快速使用区域中,2012年治疗的患者同2011年相比,校正死亡时间趋势后的死亡风险比为0.81(95%置信区间0.71至0.94),然而在对照区域内未观察到差异(1.02,0.93至1.12)。同对照区域相比,快速使用区域的90日内手术死亡率(7.0%至4.0% vs 5.0%至4.3%,P=0.01)和未接受手术与化疗的女性百分比(20.0%至17.4% v 19.0至19.5%,P=0.04)降辐较大。横断面分析证实NACT使用较大的区域的治疗与较低的死亡率相关(P=0.001)。

结论:新英格兰和东南部部地区晚期上皮性卵巢癌的NACT使用大幅度降低了确诊后3年的死亡率。
