Radiotherapy 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 radiotherapy uses a radioactive substance, such as a radiolabeled monoclonal antibody, that travels in the blood to tissues throughout the body. Also called irradiation and radiation therapy. 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 could seem apparant that, compare relapse-free survival and larynx preservation in patients with resectable hypopharyngeal or laryngeal cancer treated with sequential vs alternating cisplatin and fluorouracil and radiotherapy. Resectable, able to be removed by surgery. Relapse-free survival is in cancer, the length of time after primary treatment for a cancer ends that the patient survives without the return of any signs or symptoms of that cancer. In a clinical trial, measuring the relapse-free survival is one way to see how well a new treatment works. Also called RFS. Laryngeal, having to do with the larynx. Laryngeal cancer, cancer that forms in tissues of the larynx (area of the throat that contains the vocal cords and is used for breathing, swallowing, and talking). Most laryngeal cancers are squamous cell carcinomas (cancer that begins in flat cells lining the larynx). Relapse is the return of a disease or the signs and symptoms of a disease after a period of improvement. Larynx is the area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called voice box. Cisplatin is a drug used to treat many types of cancer. Cisplatin contains the metal platinum. It kills cancer cells by damaging their DNA and stopping them from dividing. Cisplatin is a type of alkylating agent. Fluorouracil is a drug used to treat cancers of the breast, stomach, and pancreas, and certain types of colorectal and head and neck cancers. It is also used in a cream to treat basal cell skin cancer and actinic keratosis (a skin condition that may become cancer). It is being studied in the treatment of other conditions and types of cancer. Fluorouracil stops cells from making DNA and it may kill cancer cells. It is a type of antimetabolite. Also called 5-fluorouracil, 5-FU, Adrucil, Efudex, and Fluoroplex.
- Finally, it might seem to be apparant that, PDQ Cancer Information Summaries Complementary and Alternative Medicine (CAM) Information about complementary and alternative forms of treatment for patients with cancer. PDQ, pDQ is an online database developed and maintained by the National Cancer Institute. Designed to make the most current, credible, and accurate cancer information available to health professionals and the public, PDQ contains peer-reviewed summaries on cancer treatment, screening, prevention, genetics, complementary and alternative medicine, and supportive care; a registry of cancer clinical trials from around the world; and directories of physicians, professionals who provide genetics services, and organizations that provide cancer care. Most of this information, and more specific information about PDQ, can be found on the NCI`s Web site at http://www.cancer.gov/cancertopics/pdq. Also called Physician Data Query. Medicine, refers to the practices and procedures used for the prevention, treatment, or relief of symptoms of a diseases or abnormal conditions. This term may also refer to a legal drug used for the same purpose. Alternative medicine, treatments that are used instead of standard treatments. Standard treatments are based on the results of scientific research and are currently accepted and widely used. Less research has been done for most types of alternative medicine. Alternative medicine may include special diets, megadose vitamins, herbal preparations, special teas, and magnet therapy. For example, a special diet may be used instead of anticancer drugs as a treatment for cancer. Complementary and alternative medicine, forms of treatment that are used in addition to (complementary) or instead of (alternative) standard treatments. These practices generally are not considered standard medical approaches. Standard treatments go through a long and careful research process to prove they are safe and effective, but less is known about most types of CAM. CAM may include dietary supplements, megadose vitamins, herbal preparations, special teas, acupuncture, massage therapy, magnet therapy, spiritual healing, and meditation. Also called CAM.
