Outcome is a specific result or effect that can be measured. Examples of outcomes include decreased pain, reduced tumor size, and improvement of disease. 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- Seemingly, treating head and neck cancer with radiotherapy can lead to serious loss of salivary gland function with the only current method of reducing such adverse effects being the lowering of the dose of radiotoxic therapy given. The problem with such a method is that the dose has to be substantial enough to treat the cancer and so lowering the dose may not offer the best course of treatment for patients in the long-run. Salivary gland is a gland in the mouth that produces saliva. 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. Gland is an organ that makes one or more substances, such as hormones, digestive juices, sweat, tears, saliva, or milk. Endocrine glands release the substances directly into the bloodstream. Exocrine glands release the substances into a duct or opening to the inside or outside of the body. Head and neck cancer, cancer that arises in the head or neck region (in the nasal cavity, sinuses, lips, mouth, salivary glands, throat, or larynx [voice box]).
- Apparently, patients with head and neck cancer (HNC) receiving radiation therapy (RT) alone or with concurrent chemotherapy (CRT) often develop mucositis that may lead to unplanned treatment interruptions and/or chemotherapy dose reductions. Some RT schedules have included planned treatment breaks to allow normal tissues to recover from these toxicities. 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). Mucositis is a complication of some cancer therapies in which the lining of the digestive system becomes inflamed. Often seen as sores in the mouth. Recover, to become well and healthy again. Chemotherapy, treatment with drugs that kill cancer cells. 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.
