目的:完全肿瘤细胞减灭术(cytoreductive surgery,CRS)及术后辅助化疗,是晚期原发性上皮性卵巢癌(epithelial ovarian cancer,EOC)的重要预后因素。然而,EOC患者接受辅助化疗开始时机及其与预后的关系尚不明确,值得深入探讨。方法:本研究选取2010年1月至2017年12月在印度班加罗尔马尼帕尔综合癌症中心接受完全细胞减灭术的185例晚期原发性EOC患者,其中部分患者接受腹腔化疗或辅助化疗,部分患者未接受腹腔化疗和辅助化疗。分别记录并分析术后开始进行辅助化疗的时间及其对预后的影响。结果:接受单纯CRS、CRS联合经腹腔港的腹腔内化疗(intraperitoneal chemotherapy,IP)或腹腔热灌注化疗(hyperthermic intraperitoneal chemotherapy,HIPEC)的患者分别为50例、60例和75例。CRS组术后开始接受辅助化疗的平均时间为32天,CRS+IP组为34天,CRS+HIPEC组为41天。CRS组中,术后化疗间隔时间>42天对无复发生存(relapse-free survival,RFS)期有显著影响(36个月vs. 17个月:P=0.02);在CRS+IP组中,患者RFS差异无统计学意义(35个月vs. 28个月;P=0.78);CRS+HIPEC组,RFS差异无统计学意义(35个月vs. 32个月;P=0.17)。如期行辅助化疗患者生存期较延迟化疗更好(88个月vs. 71个月,P=0.49)。结论:化疗时间延迟是单纯接受完全CRS患者RFS的不良预后因素。与非HIPEC组相比,化疗时间延迟对HIPEC组患者并未产生显著影响,其原因可能在于术中单次HIPEC弥补了化疗时间延迟带来的不利影响。
