Researchers are studying patients with cancerous solid tumors, blood disorders, and healthy HLA-compatible family members to better understand these diseases and improve treatments. This observational study collects biological samples to evaluate therapies, refine approaches, and explore prevention opportunities. Participants include those enrolled or being screened for treatment protocols at the NIH Clinical Center, as well as those receiving care through home health providers. The study collects blood, bone marrow, urine, stool, oral and nasopharyngeal samples, and tissue biopsies during routine medical care or research procedures. HLA-compatible donors may also provide white blood cells through leukapheresis, a process that separates white cells from blood. Samples are tracked, stored, analyzed, and used to study transplant effects and disease characteristics. Participants contribute samples during their medical visits or home care, with additional samples requested periodically. Assessments include collection of various biological specimens, with some procedures performed specifically for research. The main outcome is ongoing biospecimen storage. The study involves patients aged 2 years and older and may include healthy volunteers, with no set end date.
