For example, tumor markers like Ki-67 can be used to choose form of treatment or in prognostics but are not useful to give a diagnosis, while other tumor markers have the opposite functionality. Therefore it's important to follow the guidelines of the specific tumor marker. Tumor markers are mainly used in clinical medicine to support a ...
A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule." [18] In cancer research and medicine, biomarkers are used in three primary ways: [19] To help diagnose conditions, as in the case of identifying early stage cancers (diagnostic)
These tumor biomarkers are used to track the health of tumors, but cannot serve as the sole diagnostic for specific cancers. Examples of tumoral markers used to follow up cancer treatment are the Carcinoembryonic Antigen (CEA) for colorectal cancer and the Prostate Specific Antigen (PSA) for prostate cancer. [42]

Such antibodies to CEA are commonly used in immunohistochemistry to identify cells expressing the glycoprotein in tissue samples. In adults, CEA is primarily expressed in cells of tumors (some malignant, some benign) [ 19 ] but they are particularly associated with the adenocarcinomas , such as those arising in the colon, lung, breast, stomach ...
The diversity of immunohistochemistry markers used in diagnostic surgical pathology is substantial. Many clinical laboratories in tertiary hospitals will have menus of over 200 antibodies used as diagnostic, prognostic and predictive biomarkers. Examples of some commonly used markers include: BrdU: used to identify replicating cells. Used to ...
