摘要
目的探讨治疗前18F-脱氧葡萄糖(FDG) PET/CT显像对小儿神经母细胞瘤(NB)预后的预测价值。方法回顾性分析2012年6月至2015年11月间经病理证实且临床及随访资料完备的NB患者27例[男18例、女9例;平均年龄(4.6±2.4)岁],在患者治疗前行PET/CT显像,分别记录原发肿瘤最大径、原发肿瘤最大标准摄取值(Tmax)、肝脏最大标准摄取值(Lmax)及Tmax/Lmax,同时记录患者临床分期、血清铁蛋白、血清乳酸脱氢酶(LDH)及血清神经元特异性烯醇化酶(NSE)等数据。对患者进行治疗后随访(3~32个月,中位时间24个月),应用Kaplan-Meier法分析Tmax及Tmax/Lmax对患者2年无进展生存(PFS)的影响,应用Cox回归分析探讨各种因素对PFS的影响。结果27例患者中,12例(44.4%)患者病情进展。单变量分析显示,是否存在N-myc基因扩增、血清LDH水平、血清NSE水平、血清铁蛋白水平、原发肿瘤的最大径、Tmax及Tmax/Lmax均对预测2年PFS有价值;多变量分析显示,仅Tmax及Tmax/Lmax是预测2年PFS的独立预后预测因素。结论18F-FDG PET/CT显像能在小儿NB患者预后预测中提供有价值信息。
ObjectiveTo explore the prognostic value of pretreatment 18F-fluorodeoxyglucose (FDG) PET/CT in pediatric neuroblastoma (NB).MethodsTwenty-seven NB patients (18 males, 9 females; average age (4.6±2.4) years) confirmed by pathology from June 2012 to November 2015 were retrospectively included. All patients had detailed clinical and follow up data. They underwent 18F-FDG PET/CT scan before any treatment, and the largest diameter of primary tumors, maximum standardized uptake value (SUVmax) of primary tumor (Tmax), SUVmax of liver (Lmax), Tmax/Lmax ratio, clinical staging, serum ferritin, serum lactate dehydrogenase (LDH) and serum neuron-specific enolase (NSE) were recorded as prognostic factors. Patients were followed up after treatment for 3-32 months (median: 24 months). Kaplan-Meier survival analysis was used to analyze the influence of Tmax and Tmax/Lmax ratio on 2-year progression free survival (PFS). Cox regression analysis was used to comprehensive analyze the influence of various factors on PFS.ResultsOf the 27 patients, 12(44.4%) experienced disease progression during the follow-up period. Univariate analysis showed that N-myc gene amplification, serum LDH, serum NSE, serum ferritin, the largest diameter of primary tumors, Tmax and Tmax/Lmax ratio were significant prognostic factors for 2-year PFS. The multivariate analysis showed that only the Tmax and Tmax/Lmax ratio were independent prognostic factors for 2-year PFS.Conclusion18F-FDG PET/CT can provide effective information on the prognostic information for pediatric NB patients.
