Abstract
目的明确美国国家综合癌症网络国际预后指数(NCCN-IPI)对外周T细胞淋巴瘤(PTCL)患者化疗后的预后评估价值。方法回顾性分析2003年1月至2013年5月接受CHOP或CHOP样方案化疗的162例初治PTCL患者的临床资料,采用国际预后指数(IPI)和NCCN-IPI进行危险分层和预后评估。结果①162例患者预期5年总生存(OS)和无进展生存(PFS)率分别为33%和20%,中位OS和PFS时间分别为17.0和9.2个月。②多因素分析提示美国东部肿瘤协作组体能状态评分(ECOG评分)≥2分(PFS:HR=2.418,95%CI 1.535~3.809,P<0.001;OS:HR=2.347,95%CI 1.435~3.839,P=0.001)和存在特定的结外病变部位(PFS:HR=1.800,95%CI 1.216~2.665,P=0.003;OS:HR=1.608,95%CI 1.054~2.454,P=0.027)是影响患者PFS和OS的独立危险因素;ALK+是影响间变性大细胞淋巴瘤患者PFS(HR=0.424,95%CI 0.184~0.975,P=0.043)及OS(HR=0.276,95%CI 0.087~0.877,P=0.029)的独立预后良好因素。③NCCN-IPI低危组患者的生存率显著高于IPI低危组患者(5年OS率74%对54%,χ2=5.041,P=0.025;5年PFS率50%对38%,χ2=5.295,P=0.021),差异均有统计学意义。结论NCCN-IPI较IPI对低危PTCL患者具有更好的预后判断意义,可作为PTCL患者有效的预后分层工具。
