MT2011-11C: High Dose Chemotherapy and Autologous Peripheral Blood Stem Cell (PBSC) Rescue for Neuroblastoma
This therapy involves the use of consolidation chemotherapy, autologous stem cell rescue, post-transplant radiation therapy and a maintenance phase with Isotretinoin (Accutane, 13-cis-retinoic acid) therapy. If available, patients should also consider post-transplant therapy with cytokines and monoclonal antibody (ch14.18) on a COG or NANT trial. Ideally, patients should begin consolidation chemotherapy no later than 8 weeks after the start of Induction Cycle #6. (It is strongly recommended to begin consolidation within 4-6 weeks after starting Induction Cycle #6).
• Less than 30 years of age at diagnosis of neuroblastoma
• No evidence of disease progression: defined as increase in tumor size of >25% or new lesions
• Recovery from last induction course of chemotherapy (absolute neutrophil count > 500 and platelet > 20,000)
• No uncontrolled infection
• Minimum frozen peripheral blood stem cells (PBSCs) of 2 x 10^6 CD34 cells/kg for transplant are mandatory and 2 x 10^6 CD34 cells/kg for back-up are strongly recommended (thus, PBSC of 4 x 106 CD34 cells/kg is encouraged)
• Adequate organ function defined as:
• Hepatic: aspartate aminotransferase (AST) < 3 x upper limit of institutional normal 8 Cardiac: shortening fraction ≥ 27% or ejection fraction ≥ 50%, no clinical congestive heart failure 8 Renal: Creatinine clearance or glomerular filtration rate (GFR) > 60 mL/min/1.73m^2 If a creatinine clearance is performed at end induction and the result is < 100 ml/min/1.73m^2, a GFR must then be performed using a nuclear blood sampling method or iothalamate clearance method. Camera method is NOT allowed as measure of GFR prior to or during Consolidation therapy for patients with GFR or creatinine clearance of < 100 ml/min/1.73m^2 Exclusion Criteria
• Patients with progressive disease should consider participating in phase I studies since consolidation therapy using the regimen outlined in this document have not been determined to be useful.
• Patients who are delayed in consolidation chemotherapy beyond 8 weeks, and don't meet organ function criteria.
