Collection of Blood and Urine From Patients Undergoing Radiation Therapy

Background: -Research in NCI's Radiation Oncology Branch depends on the availability of blood and urine samples from patients receiving radiation therapy. Objectives: -To explore the effects of radiation therapy on gene expression in white blood cells, to measure radiation damage in red blood cells and to examine changes in hormone levels in the blood and urine after radiation therapy. Eligibility: -Patients 18 years of age and older who are receiving radiation therapy. Design: * Blood and urine samples are collected when participants enter the study. * Additional samples may be collected at different times during and after treatment. Ideally, samples are obtained before, at the completion of, and 1 month following radiation therapy. Blood samples usually will be collected during routine patient monitoring procedures and will not require an additional needle stick. * A total of 300 patients will be studied at the NCI in Bethesda, MD, Johns Hopkins University in Baltimore and the University of Pennsylvania in Philadelphia.
