Long-term Evaluation and Follow-up Care of Patients Treated With Stem Cell Transplants

While patients surviving more than three years from SCT have a high probability of being cured of their underlying disease, they are still at risk from several categories of complications which could remain lifelong risks including late recurrence (or continued persistence) of original disease, late effects from transplant related GVHD, immune dysfunction, or consequences from the chemotherapy and/or radiation given during transplant conditioning. Since these complications are iatrogenic, the long term follow-up of SCT patients is the ethical responsibility of the transplant team. In addition, collecting data on late occurring complications allows for prospective evaluation of the long term consequences of surviving a particular transplant treatment approach (i.e. total body irradiation versus chemotherapy conditioning, T cell depleted versus T cell replete transplants). This protocol is designed to allow for long term evaluation, data collection, and when needed, standard medical care of patients (and when appropriate their stem cell donor) who have received allogeneic stem cell transplantation in NHLBI protocols. This may include patients with bone marrow failure states, cytopenias, hemoglobinopathies, metastatic solid tumors, or hematologic malignancies. No investigational treatments will be administered on this protocol. Participation will not constitute a promise of long-term medical care at the NIH, nor will it provide for the evaluation and treatment of any non-transplant related medical problems. This protocol will provide access to NIH hematologists experienced in the care of post transplant patients who can help transplant patients and their local physician manage post transplant complications. In return, data collected from subjects and their donors (when applicable) will provide NIH researchers valuable information and/or laboratory samples for the purposes of better understanding the long term consequences of stem cell transplantation and identifying areas in need of future research.
