Radiation, energy released in the form of particle or electromagnetic waves. Common sources of radiation include radon gas, cosmic rays from outer space, medical x-rays, and energy given off by a radioisotope (unstable form of a chemical element that releases radiation as it breaks down and becomes more stable). Protocol is a detailed plan of a scientific or medical experiment, treatment, or procedure. In clinical trials, it states what the study will do, how it will be done, and why it is being done. It explains how many people will be in the study, who is eligible to take part in it, what study drugs or other interventions will be given, what tests will be done and how often, and what information will be collected. Cancer is a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is a cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is a cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is a cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord. Also called malignancy.
Preview- It`s possible to observe, according to recent studies, the average lifetime dose of diagnostic radiation has increased sevenfold since 1980 and more than half of all cancer patients receive radiation therapy. More and more cancer patients are receiving radiation therapy in the form of IMRT (intensity modulated radiation therapy), a rapidly growing therapy, where we believe that the pace of technology is getting ahead of proper, common sense safety protocols. Although radiation therapy, particularly in the treatment of cancer, has shown great usefulness, the tragic fact remains that when safety rules and protocols for the administration of radiation treatment are violated, the injury and harm can be deadly, as noted in the Thompson Cancer Center report, IMRT QA II. QA is a process that looks at activities or products on a regular basis to make sure they are being done at the required level of excellence. In clinical trials, QA makes sure that all parts of the trial follow the law and the Good Clinical Practice guidelines. Also called quality assurance. ALL is an aggressive (fast-growing) type of leukemia (blood cancer) in which too many lymphoblasts (immature white blood cells) are found in the blood and bone marrow. Also called acute lymphoblastic leukemia and acute lymphocytic leukemia. Radiation therapy is the use of high-energy radiation from x-rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external-beam radiation therapy), or it may come from radioactive material placed in the body near cancer cells (internal radiation therapy). Systemic radiation therapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that travels in the blood to tissues throughout the body. Also called irradiation and radiotherapy. IMRT is a type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy reduces the damage to healthy tissue near the tumor. Also called intensity-modulated radiation therapy. Therapy, treatment. Administration is in medicine, the act of giving a treatment, such as a drug, to a patient. It can
