cancer of the pancreas, stomach, breast, lung, and certain types of thyroid and ovarian cancer. Levels over 20 ng/ml before therapy are associated with cancer which has already metastasized (spread).
CEA is useful in monitoring the treatment of CEA-rich tumors. If the CEA is high before treatment, it should fall to normal after successful therapy. A rising CEA level indicates progression or recurrence of the cancer. (Chemotherapy and radiation therapy can themselves cause a rise in CEA due to death of tumor cells and release of CEA into the blood stream but that rise is typically temporary).
“Carcinoembryonic” reflects the fact that CEA is made by some cancers (“carcino-“) and by the developing fetus (“-embryonic”).
- Tumor marker, NSE
neuroblastoma, small cell lung cancer, medullary thyroid cancer, carcinoid tumors, endocrine tumors of the pancreas, and melanoma. Studies of NSE as a tumor marker have concentrated primarily on patients with neuroblastoma and small cell lung cancer. Measurement of NSE levels in patients with these two diseases can provide information about the extent of the disease […]
- Tumor necrosis factor
One of multiple proteins capable of inducing necrosis (death) of tumor cells that possess a wide range of proinflammatory actions. Abbreviated TNF. TNF is a multifunctional cytokine with effects on lipid metabolism, coagulation, insulin resistance, and the function of endothelial cells lining blood vessels. Drugs that block the action of TNF have been shown to […]
- Tumor registry
Recorded information about the status of patients with tumors. Although a registry was originally the place where information was collected (in registers), the word registry has also come to mean the collection itself. A tumor registry is organized so that the data can be analyzed. For example, analysis of data in a tumor registry maintained […]
- Trench fever
184-189, 1999). The organism (B. quintana) that causes trench fever also has been found responsible for a disease called bacillary angiomatosis in people infected with HIV and for infection of the heart and great vessels (endocarditis) with bloodstream infection. Trench fever is also called Wolhynia fever, shin bone fever, quintan fever, five-day fever, Meuse fever, […]
An abnormal, repetitive shaking movement of the body. Tremors have many causes and can be inherited, related to illnesses (such as thyroid disease), or caused by fever, hypothermia, drugs, or fear.
