摘要 目的探讨姑息预后指数(palliative prognosis index,PPI)对晚期癌症患者生存期的预测价值。方法回顾性分析2017年5月至2019年3月本院收治的160例晚期非小细胞肺癌患者的临床资料。采用Kaplan-Meier法进行生存分析;根据患者资料中的相关变量作为分组标准,进行生存期的单因素及Cox多因素分析。根据中位生存时间将160例患者分为<39天组(n=88)和≥39天组(n=72),统计并比较PPI指数、KPS评分在预测晚期癌症患者生存期方面的准确度、特异度、敏感度。结果160例晚期癌症患者的中位生存时间为39天(95%CI:35.478~42.522)。1个月、2个月、3个月的生存率分别为68.75%、37.50%、26.25%。PPI指数、KPS评分是晚期癌症患者死亡的独立危险因素。PPI指数、KPS评分在预测晚期癌症患者生存期方面的准确度、敏感度、特异度均无统计学差异(P值均>0.05)。结论PPI与晚期非小细胞肺癌患者的生存期相关,能够为患者生存期的临床预测提供依据。
