What is EGFR plasma?

Epidermal growth factor receptor (EGFR) mutation tests are in vitro diagnostic (IVD) tests used to help identify adults with non-small-cell lung cancer (NSCLC) suitable for treatment with EGFR tyrosine kinase inhibitors (EGFR‑TKIs).

What is EGFR in cancer treatment?

A substance that blocks the activity of a protein called epidermal growth factor receptor (EGFR). EGFR is found on the surface of some normal cells and is involved in cell growth. It may also be found at high levels on some types of cancer cells, which causes these cells to grow and divide.

What is EGFR marker?

Abbreviation: EGFR, epidermal growth factor receptor; EGFR-TKIs, epidermal growth factor receptor tyrosine kinase inhibitors; P, phosphorylate. In this review, we aim to summarize the role of EGFR as a prognostic marker for postoperative patients and as a predictive marker for response to cytotoxic chemotherapy.

How is EGFR testing done?

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

What is EGFR mutation test?

Aims. Activating mutations in the gene encoding epidermal growth factor receptor (EGFR) can confer sensitivity to EGFR tyrosine kinase inhibitors such as gefitinib in patients with advanced non-small-cell lung cancer. Testing for mutations in EGFR is therefore an important step in the treatment-decision pathway.

What causes abnormal EGFR?

Coronary artery disease or heart disease. Diabetes. Family history of kidney disease. Frequent urinary tract infections (UTIs) or urinary blockages.

What is normal range for EGFR?

A normal eGFR is 60 or more. If your eGFR is less than 60 for three months or more, your kidneys may not be working well.

Is EGFR hereditary?

EGFR mutations usually occur during the patient’s lifetime, although in a small number of cases the EGFR mutation can be inherited from a parent. EGFR mutations are found more frequently in never-smokers but can also occur in former smokers.

What causes EGFR?

Somatic mutations in the EGFR gene most often occur in a type of lung cancer called non-small cell lung cancer, specifically a form called adenocarcinoma. These mutations are most common in people with the disease who have never smoked.

What cancers does eGFR cause?

EGFR-positive lung cancer represents about 10-15% of lung cancer in the United States and generally appears in adenocarcinoma subtype of non-small cell lung cancer.

What does EGFR mean in lung cancer?

EGFR (epidermal growth factor receptor) is a protein on cells that helps them grow. A mutation in the gene for EGFR can make it grow too much, which can cause cancer.
