Disease control intervals in high‐risk neuroblastoma

Current salvage therapy for recurrent high‐risk neuroblastoma is rarely curative. Assessment of the effectiveness of new, primarily cytostatic agents requires the redefinition of study endpoints to reflect disease stabilization rather than tumor response or regression. The intervals of disease control in the patients in the current study with recurrent neuroblastoma were characterized to provide comparison criteria for exploratory studies of new agents.
