Purpose: To elucidate the precise reason for the better prognosis in ganglioneuroblastoma (GNB) than in neuroblastoma (NB), the prognostic factors (age at diagnosis, stage at diagnosis, primary site, N-myc amplification, Shimada classification, and ploidy) were analyzed. Methods: A retrospective analysis of the 57 neuroblastoma cases (20 GNB cases and 37 NB cases), that had not been detected by mass screening over the past 19 years at the authors' institute, was carried out. Results: A Kaplan-Meier analysis of the 5-year survival rates were 67.2% and 35.1% in cases of GNB and NB, respectively, and these rates were significantly higher in GNB (logrank test; P= .04631). No significant differences were seen between GNB and NB regarding the rate in patients 1 year of age or older (95.0% v 78.4%; P = .1005), the rate of advanced cases (60.0% v 78.4%, P = .1406), the rate of an unfavorable histology (Shimada classification, 54.5% v 68.4%, P = .4473), or the diploid pattern rate (75.0% v 76.9%, P = .9200). However, N-myc amplification was found exclusively in NB (amplified cases per examined cases; 15/31), and all cases with N-myc amplification died. When the 5-year survival rate was evaluated in the patient without N-myc amplification between GNB and NB, no significant difference was observed (logrank test; P = .8568). Conclusion: The better prognosis in patients with GNB was thus thought to be exclusively related to an absence of N-myc amplification.
