Purpose: We report the results of the French multicentric phase II study MIITOP (NCT00960739), which evaluated tandem infusions of I-metaiodobenzylguanidine (mIBG) and topotecan in children with relapsed/refractory metastatic neuroblastoma (NBL).
Methods: Patients received I-mIBG on day 1, with intravenous topotecan daily on days 1-5. A second activity of I-mIBG was given on day 21 to deliver a whole-body radiation dose of 4 Gy, combined with a second course of topotecan on days 21-25.
