Comparisons of serum NSE (a), CA125 (b) and 24-hour urine VMA (c) at baseline of the children with pediatric neuroblastoma between recurrence (n = 102) and non-recurrence (n = 163) group during 5 years follow-up. Box plots with all data points were used to present the data. *** p < 0.001. Mann Whitney test. Spearman’s correlation analysis was used to measure the correlations between serum NSE and CA125 (d), serum NSE and 24-hour urine VMA (e), serum CA125 and 24-hour urine VMA (f) in children with pediatric neuroblastoma. n = 265
