摘要: 目的 评估儿童Ⅳ期颅外恶性生殖细胞肿瘤(MGCT)化疗方案的疗效。方法 回顾分析2003年6月至2013年 12月接受Ⅳ期方案治疗和随访的患儿资料并进行统计学分析。结果 25例Ⅳ期颅外MGCT患儿中,男13例、女12例,中位 年龄2.0岁(1~11岁)。 剔除外院曾化疗的1例,诊断后放弃治疗的1例,治疗≤2个疗程病情好转中放弃治疗的3例,共20 例患儿纳入分析。其中经治疗获得完全缓解(CR)18例(90.0%),部分缓解(PR) 1例(5.0%),初治总有效率(CR+PR)为 95.0%。中位随访时间55个月(5~156个月),5年无事件生存率(EFS)及总生存率(OS)分别为(70.0±10.2) %及(82.4±9.2) %。 治疗过程中没有因合并症导致的死亡。结论 此诊疗方案对儿童颅外Ⅳ期MGCT疗效肯定。与PEB(顺铂、依托泊苷、博来 霉素)等其他化疗方案相比,药物累积剂量不大,但涉及药物较多,可能导致远期不良反应增多。

Abstract:  Objective To evaluate the outcomes of children with stage Ⅳ malignant extracranial germ cell tumors. Methods Twenty-five patients were enrolled in the retrospective analysis. Event-free survival (EFS) and overall survival (OS) rates were estimated by Kaplan-Meier method with SPSS 13.0. Results Of the 25 children, there were 13 males and 12 females. The mean age at diagnosis was 2 years old (ranged 1 to 11). Five patients receiving chemotherapy in another hospital before (n=1), or giving up treatment after confirmed diagnosis (n=1), or giving up effective treatment after received less than 2 cycles (n=3) were excluded from this analysis. Of the 20 patients, 90.0% (18/20) achieved complete remission and 5.0% (1/20) achieved partial remission after treatment. The 5-year EFS rate and 5-year OS rate were 70.0%±10.2% and 82.4%±9.2% respectively. There was no death occurred due to complications. Conclusions The effect of this treatment program is positive. The cumulative dose of the drugs is not high, compared with other schemes such as PEB, but there are more drugs involved. Whether these drugs may cause long-term adverse reactions needs further research.
