Consequently, CEA is usually present at very low levels in the blood of healthy adults (about 2–4 ng/mL). [2] However, the serum levels are raised in some types of cancer, which means that it can be used as a tumor marker in clinical tests. Serum levels can also be elevated in heavy smokers. [3]
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 ...
While numerous challenges exist in translating biomarker research into the clinical space; a number of gene and protein based biomarkers have already been used at some point in patient care; including, AFP (liver cancer), BCR-ABL (chronic myeloid leukemia), BRCA1 / BRCA2 (breast/ovarian cancer), BRAF V600E (melanoma/colorectal cancer), CA-125 ...

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]
The objective of this study was to compare different tumor markers and their diagnostic value. The tumor markers tested in this experiment were CA 19-9, CA 242 and CEA tumor markers. The data revealed that although each marker have its own level of specificity and correspond to a cancer, all three makers together increase diagnostic value. [7]
In addition to these common markers, there are prognostic markers specific to different cancer types. For example estrogen level, progesterone and HER2 are markers specific to breast cancer patients. There is evidence showing that genes behaving as tumor suppressors or carcinogens could act as prognostic markers due to altered gene expression ...
CA 27.29 is a tumor marker for breast cancer. [1] It is a form of glycoprotein MUC1. [2] References This page was last edited on 4 November 2023 ...
