UNLABELLED: Current opinion is divided about the value of excisional surgery in Evans stage III neuroblastoma. AIMS: To evaluate and correlate the survival of patients with stage III neuroblastoma with the effectiveness of the surgical excision, as assessed by (1) the surgeon (resection data) at the time of operation and (2) the pathologist (excision data). METHODS: The ENSG (European Neuroblastoma Study Group) database of 202 patients from 29 centres with proven stage III were analysed. The data include all patients with neuroblastoma diagnosed between 1982 and 1992 and their subsequent follow-up. RESULTS: Patients were grouped according to the extent of resection (100%, 75% to 99%, and < 75%) and the completeness of excision (complete, microscopic residual, macroscopic residual). There were 123 with resection data, a subgroup of 104 with excision data, and 27 with no excision. There was no statistically significant difference (log rank test) in overall survival (p = 0.11) or event-free survival between the resection subgroups, even when the data from patients without resection were included. Complete excision was associated with a highly significant survival advantage, in terms of overall survival (P = .007) and event-free survival (P = .006). This effect is most obvious among patients with the worst prognosis: older children and those with an abdominal tumour. CONCLUSION: Histological confirmation of complete excision confers a significant survival advantage for patients with stage III neuroblastoma and justifies a painstaking attempt at complete resection.
