Molecular-Guided Therapy for Relapsed and Refractory Childhood Cancer

A total of 48 neuroblastoma, brain tumor, and rare tumor patients who are refractory or relapsed on conventional therapy will be treated. Guided therapy will allow the use of any therapeutic combination (up to 4 agents) provided it includes medications contained in the study report. All patients will be followed for survival, disease response, progression and safety. All patients will be treated according to the discretion of the treating oncologist and study committee (minimum 3 oncologists and one pharmacist). Extent of disease will be measured and assessed for changes throughout the course of the study and at 6-8 week intervals (every 2 cycles).
