What is EGFR treatment?
Epidermal growth factor receptor (EGFR) is a protein on the surface of cells. It normally helps the cells grow and divide. Sometimes NSCLC cells have too much EGFR, which makes them grow faster. Drugs called EGFR inhibitors can block the signal from EGFR that tells the cells to grow.
Can EGFR lung cancer be cured?
Advanced or metastatic EGFR-mutant NSCLC isn't yet considered curable. However, many patients can have a long response (sometimes for multiple years) with EGFR-targeted therapy, though they typically become resistant to it eventually.
Is EGFR mutation treatable?
Although EGFR inhibitors can be effective treatments, they can only control the growth of the EGFR mutation lung cancer for several months or years. After a certain amount of time, a person's EGFR mutation lung cancer may become resistant to the EGFR inhibitor.
How do you reduce EGFR?
The two primary means of inhibiting the EGFR pathway are small molecule tyrosine kinase inhibitors (TKIs) and monoclonal antibodies (mAbs). EGFR TKIs (molecular weight 400–500 daltons) exert their effects intracellularly.
