Abstract

目的回顾性研究原发肠道结外鼻型NK/T细胞淋巴瘤(ENKTL)患者的临床特征、生存及影响预后的因素。方法收集2009年1月至2019年12月就诊于空军军医大学第一附属医院诊断为肠道淋巴瘤的病例,从中筛选原发肠道ENKTL并收集患者资料进行回顾性分析。结果在210例肠道淋巴瘤患者中,原发肠道ENKTL患者34例(16.2%),其中男26例,女8例,中位年龄45(20~69)岁,年龄≤60岁者占85.3%。主要症状:腹痛(76.5%)、腹泻(20.6%)、便血(29.4%)、腹部包块(2.9%),85.3%伴B症状,73.5%血清LDH升高。病变部位:大肠(52.9%)、小肠(29.4%)、大肠及小肠均受累(17.7%)。内镜分型:隆起型(8.8%)、溃疡型(32.4%)、弥漫型(2.9%)和混合型(55.9%)。Lugano分期Ⅰ/Ⅱ期24例(70.6%),Ⅳ期10例(29.4%)。组织病理免疫组化EBER阳性者占94.1%。中位生存时间为60 d。ECOG评分、血清LDH、IPI评分及是否有并发症影响患者的OS率(P值分别为0.037、0.009、0.002和0.000)。结论原发肠道ENKTL多见于青中年男性,以腹痛最多见,常合并B症状,血清LDH多异常升高,病变多位于大肠,病灶主要呈混合型或溃疡型。IPI评分低危、无并发症者OS率较高。
