Collection of Tissue Specimens From Patients With Solid Tumors or Blood Disorders and Their HLA-Compatible Family Members

Overview

This study will collect biological samples for use in research experiments aimed at better understanding the clinical features of certain diseases. The specimens may be used to evaluate the effectiveness of known therapies, refine treatment approaches, identify potential new therapies, and explore opportunities for disease prevention. The following individuals 2 years of age or older may be eligible for this study: * Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder who are being screened for or who are enrolled in a treatment study at the NIH Clinical Center * HLA-compatible donor family members (18 years of age or older) of the above patients who are being evaluated for or are enrolled in an NIH study as a stem cell transplant donor * Patients with a cancerous solid tumor or a cancerous or non-cancerous blood disorder or a bone marrow failure condition who cannot participate in an NIH treatment protocol or travel to the NIH Clinical Center and who are referred for participation through their home health care provider. Research samples will be collected from participants when blood is drawn or bone marrow, urine, or stool is collected, or tumor or other tissue is biopsied as part of their general medical care. Investigators may periodically request an additional sample of blood, stool, or urine. Participants who are 18 years of age or older may donate a large number of white blood cells through a procedure called leukapheresis. This procedure is not part of general medical care and would be done for research purposes only. For apheresis, a catheter (plastic tube) is placed in a vein in the subject's arm. Blood flows from the vein into a cell separator machine, where the white cells are separated from the red cells, platelets, and plasma by a spinning process. The white cells are removed and collected, and the rest of the blood is returned to the subject through a second tube placed in the other arm. ...

The purpose of this protocol is to collect blood, bone marrow, urine, stool, oral samples, nasopharyngeal samples and/or both malignant and non-malignant tissue from patients who are either being evaluated for enrollment, are consented to NIH Clinical Center treatment protocols, or are receiving therapy for their disease through home health care providers. Since a substantial proportion of the clinical and translational research in the NHLBI involves patients undergoing allogeneic stem cell transplantation, this protocol will also be open to people identified as suitable HLA compatible donors for patients undergoing evaluation for or already enrolled in an allogeneic stem cell transplant protocol or receiving a stem cell transplant through their home health care providers. These HLA compatible donors will serve as a source of peripheral blood mononuclear cells (peripheral blood draws or leukapheresis) for use in evaluating allogeneic graft versus host and graft-versus-tumor effects. The primary objective is to provide a mechanism for collection, tracking, storing, dispensing, analyzing, and disposing of these laboratory research samples from patients and HLA matched donors. There is no primary endpoint.
