What should your AFP tumor marker be?
An AFP level between 10 ng/mL to 20 ng/mL is normal for adults. An extremely high level of AFP in your blood—greater than 400 ng/mL—could be a sign of liver tumors. High levels of AFP may mean other cancers, including Hodgkin disease, lymphoma, and renal cell carcinoma (kidney cancer).
What is the difference between AFP and AFP-L3?
AFP-L3 reacts with L culinaris agglutinin A and it is a fucosylated variant of AFP. To differentiate an increase in AFP due to HCC or benign liver disease, AFP-L3 can be used. It means that compared with the total AFP level, the AFP-L3 isoform seems to be more specific for diagnosing HCC.
Is AFP specific for HCC?
AFP >400–500 ng/ml is considered diagnostic for HCC, although fewer than half of patients may generate levels that high 39. With values of that magnitude, the specificity of AFP is close to 100% but at a cost to the sensitivity which falls below 45% 40.
What is AFP a marker for?
Alpha-fetoprotein (AFP) is used as a tumor marker to help detect and diagnose cancers of the liver, testicles, and ovaries.
What happens if an AFP test is positive?
What does it mean if my AFP PLUS test result is screen positive? A positive AFP PLUS test means that you are in a higher likelihood group for having a baby with a neural tube defect or a chromosome abnormality. However, it does not prove by itself that there is anything wrong with the pregnancy.
What is an abnormal AFP result?
What do the results mean? If your results show higher than normal AFP levels, it may mean your baby has a neural tube defect such as spina bifida, a condition in which the bones of the spine don’t close around the spinal cord, or anencephaly, a condition in which the brain does not develop properly.
Can fatty liver cause elevated AFP?
The presence of hepatic inflammation and/or fibrosis may be the underlying cause of increased serum AFP levels in patients with severe fatty liver. Necrosis or active regeneration may also play a role in these patients.
How can I lower my AFP levels naturally?
Iron reduction therapy by phlebotomy alone or in combination with a low-iron diet is an inexpensive treatment with few side effects and may reduce the risk of hepatocarcinogenesis associated with HCV [18]. A few studies have shown that phlebotomy can reduce serum AFP levels in patients with chronic hepatitis C [34–36].
How do you confirm HCC?
Tests and procedures used to diagnose hepatocellular carcinoma include:
- Blood tests to measure liver function.
- Imaging tests, such as CT and MRI.
- Liver biopsy, in some cases, to remove a sample of liver tissue for laboratory testing.
What is the survival rate for hepatocellular carcinoma?
Unfortunately, HCC is typically diagnosed late in its course, with a median survival following diagnosis of approximately 6 to 20 months. In the United States, 2 years survival is less than 50% and 5-year survival is only 10%.
What happens if AFP is high?
If your results show high levels of AFP, it may confirm a diagnosis of liver cancer, or cancer of the ovaries or testicles. Sometimes, high levels of AFP can be a sign of other cancers, including Hodgkin disease and lymphoma, or noncancerous liver disorders.
How do you read AFP results?
Alpha fetoprotein normal range is below ten ng/ml. In the case of adults who aren’t pregnant, if the results show that there is a high level of AFP, then it indicates that you have liver disease. The AFP levels fluctuate throughout pregnancy. In pregnant women, a higher AFP level indicates Spina bifida in your fetus.
What is the sensitivity of AFP-L3 for HCC?
When the cut-off value of AFP-L3% is 5%, the sensitivity for HCC reaches 47.2% compared with that of 38% for total AFP (6). Consequently, AFP-L3 is expected to be a useful marker for HCC. 3. Proteantigen
Which is the best marker for early detection of HCC?
AFP AFP is the most widely used tumor biomarker currently available for the early detection of HCC. Findings of a previous clinical study demonstrated that serum AFP had a sensitivity of 41–65% and specificity of 80–94% when the cut-off value is 20 ng/ml (3).
What is the difference between AFP and HCC?
Additionally, a small hepatic tumor results in AFP expression being lower than the limit of detection, whereas AFP expression is delayed or higher than the limit of detection when the tumor is large, yielding AFP-negative HCC. AFP heterogeneity
How is AFP used to diagnose liver cancer?
Thus, the identification of new high sensitivity and specificity markers for HCC are essential. α-fetoprotein (AFP) together with iconography and pathology detection are commonly used in clinical early diagnosis for liver cancer.
