Your eGFR is a number based on your blood test for creatinine, a waste product in your blood. In the case of EGFR-positive non small cell lung cancer (NSCLC), a mutation, or damage, in a gene causes the EGFR to remain stuck in the “on” position. Once the biomarker testing is complete, and EGFR-positive lung cancer determined, there are many treatment options available. EGFR stands for epidermal growth factor receptor. Drugs called EGFR inhibitors can block (or target) the signal from EGFR that tells the cells to grow. The EGFR gene is divided into 28 numbered sections called exons, each of which are at risk for mutation. You still need to measure the net effect of all processes, not just the individual molecular targets. There are many clinical trials looking at other medications to treat EGFR mutation-positive lung cancer, as well as treatments for other molecular changes in cancer cells. ", Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.

What is eGFR? This can cause cells to grow out of control and lead to cancer. Elevated levels of the epidermal growth factor receptor (EGFR), a growth-factor-receptor tyrosine kinase, and/or its cognate ligands have been identified as a common component of multiple cancer types and appear to promote solid tumour growth. Doctors may also be able to check for the mutations via a special blood test called a liquid biopsy, which analyzes DNA that has been shed from tumor cells in your blood. Often, the DNA sample from a blood draw is not significant enough to make a clear diagnosis, but research is being done to find effective ways to use liquid biopsies in the diagnosis or monitoring of lung cancer. If you receive a lung cancer diagnosis, the very first thing you should do is make sure your doctors have ordered comprehensive biomarker testing done on your lung cancer tumor. For some NSCLC sufferers there is a mutation (or damage) to the gene coding for this protein which means it can be significantly over expressed. Kozuki T.
