Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Autologous stem cell rescue is an established therapy in high risk neuroblastoma and relapsed Hodgkin's lymphoma and an experimental therapy in some other solid and brain tumors to facilitate the use of very intense chemotherapy beyond bone marrow tolerance. It is usually tolerated with acceptable toxicity and graft failure is practically not existent. But whereas immune reconstitution in allogeneic hematopoietic stem cell transplantation (HSCT) setting is widely studied, the investigators have no comprehensive data available in the autologous setting regarding recovery of the innate and adaptive immune system. However, observations in patients with autoimmune disease undergoing autologous HSCT suggest not an exact recovery of the patient's pre-transplant immune system but some re-education during reconstitution of immune function. Also, recent developments of cancer-directed immunotherapy with monoclonal antibodies and immunocytokines rely on activity of the patient's own immune system via complement-mediated or antibody-dependent cellular cytotoxicity. These novel therapies are given either with or shortly after conventional chemotherapy. To find the optimal time point for administration of immunotherapy, it is important to know how and when immune effector cells recover after conventional myelosuppressive and/or immunosuppressive chemotherapy which are used in Induction regimens. Researchers at St. Jude Children's Research Hospital want to study the research participant's immune profile once prior and at multiple set time points after autologous stem cell infusion during the recovery process. In a subset of participants the investigators want to study the recovery of lymphocyte subsets and function after one course of conventional chemotherapy preceding the high dose chemotherapy and autologous stem cell transplant. That way the investigators hope to learn about the pace and order of recovery and the functional capacity of different compartments of the immune system during reconstitution.
