What is a normal range for tumor markers?
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
What does a high CA 27/29 mean?
Generally, the higher the CA 27-29 level, the more advanced the breast cancer or larger the tumor burden. If the tumor produces CA 27-29, then tumor marker levels tend to increase as the tumor grows. The highest levels may be seen in metastatic breast cancer, particularly with metastases to the liver or the bones.
What is considered a high level of CA 19 9?
Here is what your results may mean: If your CA 19-9 is less than 37 U/mL, you may not have cancer. If your CA 19-9 is above 37 U/mL, you may have cancer of the pancreas, liver, gallbladder, lung, colon, or stomach.
What is a good CA 125 level?
The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer. Your doctor may recommend other tests and procedures to determine your diagnosis.
What is a normal CA 27-29?
Healthcare providers measure CA 27-29 in units per milliliter (U/mL). A normal test should be less than or equal to 38 U/mL. Here is what your test results may mean: If your CA 27-29 is less than 38 U/mL, it may mean that you don’t have active breast cancer.
What does a CA125 of 11 mean?
What is a normal c125?
Results of the CA 125 test are measured in units per milliliter (U/mL). The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer.
Are there any clinical guidelines for tumor markers?
The American Society of Clinical Oncology (ASCO) has developed and published clinical practice guidelines on a variety of topics, including tumor markers for breast cancer, colorectal cancer, lung cancer, and others.
Can a elevated tumor marker be a sign of cancer?
Although an elevated level of a circulating tumor marker may suggest the presence of cancer, this alone is not enough to diagnose cancer. For example, noncancerous conditions can sometimes cause the levels of certain tumor markers to increase.
What is the most common tumor marker for colon cancer?
For example, carcinoembryonic antigen (CEA) is a tumor marker used in colon cancer, yet only 70-80% of colon cancers make CEA. This means 20-30% of people with colon cancer will not have a raised CEA level.
Which is a tumor marker for hepatocellular cancer?
A serum test used as a tumor marker for hepatocellular cancer. Elevated alpha-fetoprotein levels are also found in certain ovarian and teratocarcinoma or embryonal carcinoma of the testis. Elevated alpha-fetoprotein levels are not found in other histologies of testicular cancer.
