Chemoembolization: Chemoembolization is a procedure in which anticancer drugs are administered directly into the tumor and the blood supply to the tumor is then blocked by injection of an embolizing- or blocking agent. This permits 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 chemical messengers and were first found attracting white blood cells to areas of inflammation. Chemokines are involved in several forms of acute and chronic inflammation, infectious diseases, and cancer.
- Chemokine receptor
Chemokine receptor: A molecule that receives a chemokine and associated proteins (chemokine docks). Several chemokine receptors are essential co-receptors for the HIV virus.
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 cancer.
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.
