摘要：

The CpG island methylator phenotype (ClMP) was closely associated with poor overall survival (OS) in Japanese neuroblastoma (NBL) cases in our previous study. Here, in German NBL cases, CIMP(+) cases (n = 95) showed markedly poorer OS (hazard ratio (HR) = 9.5; P < 0.0001) and disease-free survival (DFS) (HR = 5.4; P < 0.0001) than CIMP(-) cases (n = 50). All the 23 cases with N-myc amplification had CIMP. Among the remaining cases without N-myc amplification, CIMP(+) cases (n 27) had a poorer OS (HR = 4.5; P = 0.02) and DFS (HR = 5.2; P < 0.0001) than CIMP(-) cases (n = 95). In multivariate analysis, CIMP and N-myc amplification had an influence on OS and DFS independent of age and disease stage. CIMP had a stronger influence on DFS than N-myc amplification while N-myc had a stronger influence on OS. (c) 2006 Elsevier Ireland Ltd. All rights reserved.
