The Italian Neuroblastoma Registry was investigated to describe 781 children with neuroblastoma experiencing tumour recurrence (424 progressions and 357 relapses). Ten-year overall survival (OS) was 6.8% (95% confidence interval (CI) 4.3-10.0) after progression and 14.4% (95% CI 10.5-18.9) after relapse. For both circumstances, OS was better for age at diagnosis <18 months, less advanced International Neuroblastoma Staging System (INSS) stage, normal lactate dehydrogenase (LDH) serum level, normal MYCN gene status (P<0.001) and a non-abdominal primary site (P=0.034 for progression, and P=0.004 for relapses). A local type of recurrence had a significantly better outcome only in case of relapse (P<0.001). Probability of survival increased by era of diagnosis. Survival of children with recurrent neuroblastoma is very poor. A small cohort of patients, mainly represented by children with stages 1 and 2 who underwent local recurrence or developed late relapse may still benefit from further conventional treatment. For the remaining larger proportion of patients, experimental therapies should be proposed.
意大利神经母细胞瘤注册研究旨在描述 781 例经历肿瘤复发的神经母细胞瘤患儿(424 例进展和 357 例复发)。进展后 10 年总生存率(OS)为 6.8%(95%置信区间(CI)4.3-10.0),复发后为 14.4%(95%CI 10.5-18.9)。对于这两种情况,诊断时年龄<18 个月、国际神经母细胞瘤分期系统(INSS)分期较低、乳酸脱氢酶(LDH)血清水平正常、MYCN 基因状态正常(P<0.001)和非腹部原发部位(进展时 P=0.034,复发时 P=0.004)的患者 OS 更好。仅在复发的情况下,局部复发类型的预后才有显著改善(P<0.001)。诊断时的时代与生存概率呈正相关。复发性神经母细胞瘤患儿的生存状况非常差。一小部分患者,主要是接受局部复发或晚期复发的 1 期和 2 期患儿,可能仍受益于进一步的常规治疗。对于其余比例较大的患者,应提出实验性治疗。
