What is a tumor marker? Tumor marker testing and cancer treatment Tumor markers and personalized cancer therapy Where are the tumor markers? Can all cancers be diagnosed with tumor markers? The most common tumor markers AFP (alpha phytoprotein) BCL2 BRCA1 and BRCA2 CA 19-9 Carcinoembryonic antigen (CEA) Fibrin/fibrinogen lactate dehydrogenase (LDH) prostate specific antigen (PSA) thyroglobin Type UGT1A1\*28 How is the tumor marker test? How long does it take to prepare the tumor marker test? Normal range of tumor markers What does the increase of tumor markers mean? What does the reduction of tumor markers mean? What is the cause of false increase of tumor markers? Does stress increase tumor markers? Tumor markers are particles that provide information about certain types of cancer.. They may be proteins released by cancer cells or DNA changes inside these cells.. They help the doctor to diagnose and get more information about the type of cancer.. What is a tumor marker?.. Any particle that is a sign of cancer in your body is called a tumor marker.. In general, proteins produced by cancer cells are called tumor markers.. But Sometimes non-cancerous cells also produce tumor markers in response to cancer.. Also, a tumor marker can be a genetic change (mutation) in tumor cells... The following names are also used for tumor markers: - Tumor test - Tumor/cancer genetic testing - Genomic testing or molecular cancer testing - Cancer somatic test Cancer marker - Biomarker It is important to know that tumor marker testing is different from genetic cancer testing. In genetic cancer testing, inherited mutations that are associated with cancer risk are checked. Tumor marker testing and cancer treatment. Tumor markers, along with other tests, help to: - Diagnosis of the type of cancer - Choosing the type of treatment - Determination of response to treatment - Estimate the probability of recovery - Recurrence of some cancers Some tumor markers provide information about a specific type of cancer, and others provide information about more than one type of cancer.. For example, people with cancer who have specific genetic changes in the EGFR gene respond well to EGFR inhibitor drugs. In these cases, tumor marker testing helps identify mutations in this gene and select treatment. And treatment is based on genes, proteins, and other cellular factors. In cancer, personalized treatment means using biomarkers and other tests to select the best and most effective treatment method. It is not, but recent findings in science and technology have played an important role in its development.. Type of cancer... Some of these changes affect response to treatment.. However, personalized therapy is not yet part of the routine treatment options in most cancers.. In general, there are 2 types of tumor markers: - There are mobile tumor markers in blood, urine, feces, saliva or bone marrow.... - Tumor markers of cancerous tissue.... Are all cancers detectable with tumor markers?... No, currently most cancers do not have known tumor markers.... In these cases, the doctor recommends laboratory tests or other imaging such as CT or MRI... The most common tumor markers ### AFP (alpha phytoprotein) Measuring the amount of AFP in a blood sample helps to diagnose and determine the response rate to treatment in liver cancer, testicular cancer and other germ cell tumors.... ### BCL2 Investigating BCL2 gene rearrangement in blood, bone marrow or tumor samples helps to diagnose and choose the type of treatment in leukemia and lymphoma.... ### BRCA1 and BRCA2 Examining BRCA1 and BRCA2 mutations in blood, saliva or tumor samples helps to diagnose, choose the screening method and type of treatment in breast cancer and ovarian cancer.... ### CA 19-9 Examining CA 19-9 in blood samples helps to diagnose and the success rate of treatment in pancreatic, gall bladder, bile duct and stomach cancer.... ### Carcinoembryonic Antigen (CEA) Examining CEA in blood samples helps to diagnose, the rate of response to treatment or recurrence of colon cancer.... ### Fibrin/Fibrinogen Measurement of fibrin in urine samples helps to determine the response to treatment in bladder cancer.. ### Lactate dehydrogenase (LDH) Measuring LDH in blood samples helps to determine the stage and response to treatment in leukemia, lymphoma, melanoma, neuroblastoma and germ cell tumors. ### Prostate Specific Antigen (PSA) Measuring PSA in a blood sample helps to diagnose, the success rate of treatment and recurrence of prostate cancer.... ### thyroglobin Measurement of thyroglobin in blood sample helps to diagnose, response to treatment and recurrence of thyroid cancer.... ### type UGT1A1*28 Examining the UGT1A1\*28 genotype in blood or saliva samples is used to diagnose colon cancer and predict the response to a type of chemotherapy drug called irinotecan. - Blood.... - Saliva.... - Urine.... - Stool.... - Biopsy....Doctors order this test to diagnose, choose a type of treatment, or respond to treatment....Sometimes multiple tumor markers are tested in the same type of cancer....How long does it take for a tumor marker test to be ready?...It depends on several factors, such as the type of tumor marker requested...Usually the results of the blood, urine, stool, or saliva test may be available within a day or two. Get ready.. The normal range is different for each type of tumor marker.... Consult your doctor to know the types of tumor markers for each type of cancer.... What does an increase in tumor markers mean?.. **Increasing tumor markers** can be a sign of cancer... It can also be caused by its progress or metastasis.... What does a decrease in tumor markers mean?.. **Decreasing tumor markers** can be a sign of treatment effectiveness.... In general, it is normal for tumor markers to rise and fall even during treatment. Since it is difficult to measure them continuously, doctors prefer to request this test together with other diagnostic tests. What is the cause of false increase of tumor markers? In many non-cancerous cases, tumor markers are increased. The most common ones are: - Anemia.... - Thyroid disorder.... - Benign ovarian cyst.... - Kidney disorders.... - Kidney stones.... - Hepatitis.... - Sarcoidosis.... Does stress increase tumor markers?.. Studies show that high stress can cause or relapse cancer in people who have had a history of cancer.. **The cost of tumor marker testing** varies according to their type and the number of markers checked.
