Toxic, having to do with poison or something harmful to the body. Toxic substances usually cause unwanted side effects. Chemotherapy, treatment with drugs that kill cancer cells. 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- Apparently, furthermore, in most solid tumors increasing the doses of cytotoxic drugs above the standard ones will strikingly increase toxic effects with little, if any, improvement in efficacy, especially for non-small-cell lung cancer which has a low sensitivity to most cytotoxic drugs. Lung cancer, cancer that forms in tissues of the lung, usually in the cells lining air passages. The two main types are small cell lung cancer and non-small cell lung cancer. These types are diagnosed based on how the cells look under a microscope. Sensitivity, when referring to a medical test, sensitivity refers to the percentage of people who test positive for a specific disease among a group of people who have the disease. No test has 100% sensitivity because some people who have the disease will test negative for it (false negatives). Cell is the individual unit that makes up the tissues of the body. All living things are made up of one or more cells. Efficacy, effectiveness. In medicine, the ability of an intervention (for example, a drug or surgery) to produce the desired beneficial effect. Cytotoxic, cell-killing. Lung, one of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body.
- It really is clear that, definitive evidence of these findings through prospective trials could affect the treatment and outcome of many patients receiving chemotherapy, they added. Prospective is in medicine, a study or clinical trial in which participants are identified and then followed forward in time. Outcome is a specific result or effect that can be measured. Examples of outcomes include decreased pain, reduced tumor size, and improvement of disease.
- It could seem apparant that, advise patients that neutropenia, a side effect, may be a surrogate marker for optimum dosing of chemotherapy drugs in patients with non-small-cell lung cancer. Neutropenia is a condition in which there is a lower-than-normal number of neutrophils (a type of white blood cell). Marker is a diagnostic indication that disease may develop. Side effect is a problem that occurs when treatment affects healthy tissues or organs. Some common side effects of cancer treatment are fatigue, pain, nausea, vomiting, decreased blood cell counts, hair loss, and mouth sores.
