What is normal CEA for breast cancer?
The cut-off values of CEA and CA15-3 were 5.0 ng/mL and 25 U/mL, respectively, and the value was considered positive or negative for the marker if the level was above or below the cut-off value, respectively.
What is a high tumor marker number for metastatic breast cancer?
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.
Is CEA elevated in breast cancer?
In breast cancer, elevated CEA is associated with metastatic disease. Preoperative CEA measurements have been shown to correlate with pathological stage and tumor extent and is stage dependent. Circulating levels of CEA in breast cancer patients are directly dependable on the size of both primary and metastatic tumor.
Can a CEA blood test detect breast cancer?
High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema. A CEA test can’t tell you what kind of cancer you have, or even whether you have cancer. So the test is not used for cancer screening or diagnosis.
How high can breast cancer tumor markers go?
How are the results of a tumor marker test interpreted?
| Marker test | Normal | High |
|---|---|---|
| CA 27-29 | Less than 38 U/mL | 38 U/mL or higher |
| CA125 | Less than 35 U/mL | Greater than 35 U/mL |
| CEA | Less than 2.5 ng/mL | Extensive disease: Greater than 10 ng/mL Metastatic disease: Greater than 20 ng/mL |
| CTCs | N/A | Greater than 5 CTCs per 7.5 mL of blood |
How high do CEA markers go?
Normal Results The normal range is 0 to 2.5 ng/mL (0 to 2.5 µg/L). In smokers, slightly higher values may be considered normal (0 to 5 ng/mL, or 0 to 5 µg/L).
What can falsely elevated CEA?
Diabetes, smoking, chronic obstructive pulmonary disease, and colonic polyps were considered as causes of false elevation. The false-positive rates of CEA according to level were as follows: 5.1–10.0 ng/mL, 99.5%; 10.1–15.0 ng/mL, 87.2%; 15.1–20.0 ng/mL, 100.0%; >20.0 ng/mL, 33.3%.
Is CEA level 8 high?
A CEA value of greater than 8 ng/ml was highly suggestive of residual disease or recurrence, even when no clinical evidence was present. Approximately 90% of the patients dying from colorectal cancer showed an increase in CEA to greater than 8 ng/ml during the course of the disease.
What is a normal CEA tumor marker?
The normal range for CEA is 0 to 2.5 nanograms per milliliter of blood (ng/mL). If CEA levels remain elevated during treatment, your treatment may not have been as successful as hoped. Anything greater than 10 ng/mL suggests extensive disease, and levels greater than 20 ng/mL suggest the cancer may be spreading.
What is the highest CEA level?
What are the causes of Elevated CEA?
– Cancer: It is a tumor marker and raises in the presence of a malignant tumor. – In inflammatory bowel diseases (ulcerative colitis, diverticulitis, Crohn’s, etc.). – Liver disease ( cirrhosis, hepatitis, etc.).
What is normal range for CEA marker?
What is normal range for CEA marker? Normal Results The normal range is 0 to 2.5 ng/mL (0 to 2.5 µg/L). In smokers, slightly higher values may be considered normal (0 to 5 ng/mL, or 0 to 5 µg/L). Does CEA increase with age?
What are tumor markers in breast cancer?
The most common tumor markers used for prognosis in breast cancer are the estrogen receptor assay (ERA) and the progesterone receptor assay (PRA). Both are steroid hormones receptors. ERA and PRA are used to estimate the potential response to endocrine, or hormone, therapy.
