Chemoprophylaxis
|
|
ChemoprophylaxisPrevention of disease by the use of chemicals or drugs.
RELATED TERMS--------------------------------------
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
SIMILAR TERMS--------------------------------------
Chemet
Chemet is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): succimer.
Chemical menopause
Menopause induced by chemotherapy or other chemicals or medications.
Chemical reaction
A process in which one substance is transformed into another. Thousands of different types of chemical reactions occur in the body and are essential to its structure and function.
Chemo
Slang for chemotherapy -- drug therapy for cancer.
Chemobrain
Cognitive dysfunction associated with chemotherapy. It is thought that chemotherapy may cause memory loss, attention loss, and other problems that make it difficult for patients to think clearly. Also known as chemo-brain, chemo-fog, and chemotherapy-related cognitive dysfunction.
Chemoembolization
A procedure in which the blood supply to a tumor is blocked and anticancer drugs are administered directly into the tumor, permitting a much higher concentration of drugs to be in contact with the tumor for a longer period of time, while depriving the tumor of oxygen and nutrients. The procedure is used to treat cancer originating in the liver (primary liver cancer) as well as cancer that has metastasized (spread) to the liver from another area.
Chemokine
One of a large group of proteins that act as lures and were first found attracting white blood cells. The chemokines are involved in a wide variety of processes including acute and chronic types of inflammation, infectious diseases, and cancer. Chemokines may lure cancer cells and help determine the sites to which cancer cells spread by metastasis.
Chemokine receptor
A molecule that receives a chemokine and a chemokine dock.
Chemokinesis
The response of a cell to a chemical that causes the cell to make some kind of change in its movement by speeding it up, slowing it down or changing its direction. The molecules that achieve these results are called chemokines.
Chemoprevention
The use of natural or laboratory-made substances to prevent a disease such as cancer. The regular use of aspirin is known to reduce the risk of the polyps from which colorectal cancer arises. This is an instance of chemoprevention. The term chemoprevention was coined to parallel the term chemotherapy. Chemoprevention prevents and chemotherapy treats. Chemoprevention is also called chemoprophylaxis.
Chemoradiotherapy
The combination of simultaneous chemotherapy and radiation therapy. Chemoradiotherapy before surgery has been found to reduce the risk of local recurrence of rectal cancer.
Chemosense
The chemical sensing system. The sense of smell is part of our chemical sensing system, or the chemosenses.
Chemosis
Swelling around the iris (the colored circle that surrounds the pupil) due to edema (swelling) of the bulbar conjunctiva (the clear membrane that coats the outer surface of the eye).
Chemotaxis
The movement of cells in response to chemical messengers. The movement of neutrophils and macrophages into damaged tissues is brought about by signals released by damaged tissues, and bacterial products. The term applies to the movement of any organism attracted by a specific chemical, which may be a suitable nutrient.
Chemotherapy
The use of chemicals (medicines) to treat cancer.
Chemotherapy, adjuvant
Chemotherapy (drug therapy) that is given after tumor surgery.
Chemotherapy, topical
Treatment with an anticancer drug in a lotion, ointment or cream that is applied to the skin.
PREVIOUS AND NEXT TERMS--------------------------------------
Coordinating centre
Headquarters for a multisite trial that collects all data.
Coordinating committee
A committee that a sponsor may organise to coordinate the conduct of a multicentre trial.
Correlation
The relationship of one variable to another, not to be confused with causation.
Crossover trial
In crossover trials, each subject receives both treatments being compared (often the test drug for one period and the placebo for another period). Such trials are used for patients who have a stable, usually chronic, condition during both treatment period.
Cerebrospinal
Relating to the brain and the spinal cord.
Chemoprophylaxis
Cholinergic
Relating to nerve cells or fibers that employ acetylcholine as their neurotransmitter.
Coagulopathy
A disease affecting the coagulability of the blood.
Coccobacillus
A short, thick bacterial rod of the shape of an oval or slightly elongated coccus.
Carcinogenic
Of a substance which causes cancer.
Chronic obstructive pulmonary disease (COPD)
A progressive lung disease process characterized by difficulty breathing, wheezing, and a chronic cough. Complications include bronchitis, pneumonia, and lung cancer.
