Antigen 1). tumor-specific antigen. tumor-specific antigen (TSA) any cell-surface antigen of a tumor that does not occur on normal cells of the same origin. V antigen (Vi antigen) an antigen contained in the sheath of a bacterium, as Salmonella typhosa (the typhoid bacillus), and thought to contribute to its virulence.. any of several antigens, coded for by the viral genome, associated with transformation of infected cells by certain DNA tumor viruses. Called also tumor antigen. 2. an antigen present on human erythrocytes that is exposed by treatment with neuraminidase or contact with certain bacteria.

How the Cancer Antigen 27.29 Test Is Used to Monitor Breast Cancer Cancer Antigen 27.29 (CA 27.29) - Definition. Cancer antigen 27.29 (CA 27.29) is a blood test that is done specifically for people with breast cancer. It is one of the tumor markers that can be used to monitor the course of the disease. One version of this test is called the Truquant BR Radioimmunoassay test..

Tumor Markers; AFP, HCG, CA-125 Tumor marker, CEA: Carcinoembryonic antigen (CEA) is a protein found in many types of cells but associated with tumors and the developing fetus.CEA is tested in blood. The normal range is.Benign conditions that can increase CEA include smoking, infection, inflammatory bowel disease, pancreatitis, cirrhosis of the liver, and some benign tumors (in the same organs which have cancers with increased CEA).EA is tested in blood.

Clinical Applications of Monoclonal Antibodies With solid tumors, cell type specificity becomes an issue as there are not many specific targets for monoclonal antibodies that are not cross-reactive with antigens on normal tissues. Trastuzumab is the most widely used monoclonal antibody against solid tumor in the USA.As an alternative first-line monotherapy, trastuzumab has demonstrated efficacy and safety in patients with metastatic breast cancer that has rarely been seen with other medicinal approaches.Table 1.ith solid tumors, cell type specificity becomes an issue as there are not many specific targets for monoclonal antibodies that are not cross-reactive with antigens on normal tissues.

Tumor Markers; AFP, HCG, CA-125 Tumor markers are molecules occurring in blood or tissue that are associated with cancer and whose measurement or identification is useful in patient diagnosis or clinical management.he PSA screening test is a blood test that looks for a specific tumor marker. In general, tumor markers are produced by the tumor itself or by our body in response to the presence of cancer or non-cancerous conditions.

- The carcinoembryonic antigen (CEA) test may be used: 1  To monitor the treatment of people diagnosed with colon cancer. It may also be used as a marker for medullary thyroid cancer and cancers of the rectum, lung, breast, liver, pancreas, stomach, and ovaries. An initial CEA test is typically ordered prior to treatment as a baseline value.

- Ado-trastuzumab emtansine (Kadcyla) is one such drug approved to treat HER2-positive breast cancer. Ado-trastuzumab emtansine contains an antibody that attaches to the HER2 receptors on the breast cancer cells.The cancer cells then ingest the antibody, which releases a few molecules of chemotherapy.The chemotherapy only damages the cancer cells, leaving the surrounding healthy cells undamaged. A number of monoclonal antibody drugs are available to treat various types of cancer.Clinical trials are studying monoclonal antibody drugs in treating nearly every type of cancer.he cancer cells then ingest the antibody, which releases a few molecules of chemotherapy.

Tumor marker A tumor marker is a biomarker found in the blood, urine, or body tissues that can be elevated in cancer, among other tissue types.here are many different tumor markers, each indicative of a particular disease process, and they are used in oncology to help detect the presence of cancer. An elevated level of a tumor marker can indicate cancer; however, there can also be other causes of the elevation.

Immune system The main response of the immune system to tumors is to destroy the abnormal cells using killer T cells, sometimes with the assistance of helper T cells. Tumor antigens are presented on MHC class I molecules in a similar way to viral antigens. This allows killer T cells to recognize the tumor cell as abnormal.

Prostate Specific Antigen (PSA) Prostate specific antigen (PSA) is a protein produced primarily by cells in the prostate, a small gland that encircles the urethra in males and produces a fluid that makes up part of semen. Most of the PSA that the prostate produces is released into this fluid, but small amounts of it are also released into the bloodstream. This test measures the amount of PSA in the blood. The PSA test is used as a tumor marker to screen for and to monitor prostate cancer.

- Carcinoembryonic Antigen Test (CEA). A carcinoembryonic antigen (CEA) test is a blood test used to help diagnose and manage certain types of cancers, especially cancer of the colon.The test measures the amount of CEA present in the blood. If you already have cancer, this test helps a doctor determine if the treatment for the cancer is working. CEA test is most useful to monitor patients who already have been diagnosed with a type of cancer that is known to produce CEA. Not all cancers produce CEA. Increased levels of CEA may be found in the following cancers: 1  colorectal (colon) cancer. 2  medullary thyroid carcinoma.

Prostate-Specific Antigen (PSA) Test Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The PSA test measures the level of PSA in a man’s blood. For this test, a blood sample is sent to a laboratory for analysis. The results are usually reported as nanograms of PSA per milliliter (ng/mL) of blood.

Biology - Cancer Blood tests for tumor antigens/antibodies produced against tumors are called tumor marker tests. They can be used to detect first-time cancer and cancer relapses. Genetic Tests When individuals test positive for the presence of marker genes, such as the BRCA1 breast cancer oncogene, they should be vigilant for signs of cancer.
