摘　　要：背景伴有MYCN基因扩增的神经母细胞瘤(NB)患儿的长期生存率不容乐观,目前国内相关大宗病例报道不多。目的总结伴有MYCN基因扩增的NB患儿的临床特征、治疗效果及预后相关因素。设计病例系列报告。方法纳入2007年2月1日至2020年1月30日首都医科大学附属北京儿童医院血液肿瘤中心确诊NB且经荧光原位杂交法确定伴有MYCN扩增的患儿,分析患儿瘤灶部位、大小、转移部位、肿瘤标记物、病理亚型、治疗情况及影响预后的相关因素。主要结局指标3年生存影响因素。结果纳入133例MYCN扩增的NB患儿,占同期收治总NB患儿的12.0%。男82例,女51例,中位发病年龄(35.7±9.8)个月;原发瘤灶位于腹膜后及肾上腺区129例(97.0%),位于后纵隔区域4例(3.0%);骨髓转移81例(60.9%),骨骼转移80例(60.2%),中枢转移24例(18.1%);99例(74.4%)血清LDH≥1500 U·L^(-1),126例(94.7%)神经元特异性烯醇化酶≥100 ng·mL^(-1);原发瘤灶最大直径≥10 cm者89例(66.9%)。3年OS和EFS分别为(19.7±3.5)%和(19.0±3.6)%。78例进展复发,在诱导、巩固、维持及停药后进展复发分别为8、20、46和4例,进展复发的部位以原发瘤灶、骨髓、中枢神经系统及骨骼最常见,中位首次进展时间为11.3月。伴有骨髓、骨转移、合并1p36缺失、年龄<18月及未行自体外周血造血干细胞移植患儿预后不良。结论伴有MYCN扩增的NB患儿原发瘤灶以腹膜后肾上腺区为主,早期远处转移率高,50%以上患儿在维持治疗期间肿瘤进展,3年OS仅为19.7%。伴有MYCN扩增的NB患儿迫切需要靶向治疗等新的治疗手段,以提高疗效,改善预后。Background The long-term survival of children with neuroblastoma(NB)associated with MYCN amplification is not promising,and few studies have been previously reported in China.Objective To summarize the related factors of clinical characteristics,therapeutic effect and prognosis in NB children with MYCN amplification and to further improve the recognization of this group in NB.Design Case series report.Methods The clinical information of NB with MYCN amplification,diagnosed and treated from Feb 2007 to Jan 2020,were analyzed retrospectively,and the tumor location,size,metastasis,treatment,and risk factors affecting the prognosis were analyzed.Main outcome measures Factors affecting the 3-year survival of NB with MYCN amplification.Results A total of 133 NB patients with MYCN-Amp were included in this study,accounting for 12.02%of total NB patients in the same period in our center.The median age of onset was 35.7±9.8 months.There were 129 cases(97%)located in abdomen region and 4 cases(3%)in posterior mediastinal region.There were 81 cases(60.9%)with bone marrow metastasis,80 cases(60.2%)with bone metastasis and 24 cases(18.1%)with central nerves system metastasis.Serum LDH≥1500 U·L^(-1) was shown in 99 cases(74.4%).NES≥100 ng·mL^(-1) was found in 126 cases(94.7%).The largest tumor diameter(>10 cm)was in 89 cases(66.9%).The 3-year OS and EFS were 19.7%and 19.0%.There were 78 cases of progressive recurrence,8,20,46 and 4 cases of progressive recurrence happened at induction,consolidation,maintenance and withdrawal,respectively.Primary tumor,bone marrow,central nervous system and bone were the most common sites of progressive recurrence.The median time of first progression was 11.3 months.Bone marrow and bone metastasis,deletion of 1p36 were risk factors.Conclusion A single center with large sample of MYCN-Amp NB showed that the primary tumor was predominantly located in the retroperitoneal adrenal region,with a high rate of early distant metastasis,and more than 50%of the children developed tumor progression
