In our study tumour stage was significantly predictive of outcome (p<0.001), especially for patients with advanced disease (Stage III (p=0.0171) and IV (p<0.001)). Our findings therefore correlated with the MaGIC analysis which demonstrated a statistically significant relationship between stage IV disease, and poor outcome, particularly in children over 11 years of age with advanced stage extragonadal tumours and metastatic ovarian tumours (18). Earlier studies also documented that advanced disease was predictive of poorer outcomes (26, 27).
