Lancet oncol:癌症幸存患儿的实体器官移植率

2019-08-28 MedSci MedSci原创

癌症患儿幸存者常发生严重的慢性疾病。研究人员对癌症患儿因终末器官损伤进行实体器官移植的概率和危险因素进行研究,同时评估这类患儿器官移植后的5年存活率。研究对象为1970年1月1日-1986年12月31日期间,21岁前确诊癌症后存活5年以上的个体。受试者所患的癌症有白血病、淋巴瘤、恶性中枢神经系统肿瘤、神经母细胞瘤、威尔姆斯瘤、骨及软组织肉瘤。共13318位符合要求的患儿,100位进行了实体器官移植

癌症患儿幸存者常发生严重的慢性疾病。研究人员对癌症患儿因终末器官损伤进行实体器官移植的概率和危险因素进行研究,同时评估这类患儿器官移植后的5年存活率。

研究对象为1970年1月1日-1986年12月31日期间,21岁前确诊癌症后存活5年以上的个体。受试者所患的癌症有白血病淋巴瘤、恶性中枢神经系统肿瘤、神经母细胞瘤、威尔姆斯瘤、骨及软组织肉瘤。

共13318位符合要求的患儿,100位进行了实体器官移植(50位肾脏、37位心脏、9位肝脏、7位肺),67位登记等待移植(21位肾脏、25位心脏、15位肝脏、6位肺)。在确诊癌症后35年,肾、心、肝、肺移植或等待移植的累计发生率分别为0.54%(95% CI 0.40–0.67)、0.49%(0.36-0.62)、0.19%(0.10-0.27) 和0.10%(0.04-0.16)。肾移植的风险因素为单侧肾切除(HR 4.2,95% CI 2.3-7.7)、异环磷酰胺(24.9,7.4-83.5)、全身放疗(6.9,2.3-21.1)和平均肾放疗>15Gy(15-20Gy,3.6[1.5-8.5];>20Gy,4.6[1.1-19.6]);心脏移植的风险因素是蒽环霉素和平均心脏放疗>20Gy(均为剂量依赖性);肝移植的风险因素是放线菌素D(3.8,1.3-11.3)和甲氨蝶呤(3.3,1.0-10.2);肺移植的风险因素是卡莫司汀(12.3,3.1-48.9)和平均肺放疗>10Gy(15.6,2.6-92.7)。肾、心、肝、肺移植后的5年总体存活率分别为93.5%、80.6%、27.8%和34.3%。

在年长的儿童癌症形成者中,实体器官移植并不常见。器官特异性的放疗可增加该器官移植的发生率。幸存5年以上的重度终末器官衰竭的癌症患儿应被纳入器官移植人群。
