EGFR mode of action
Binding of EGF to the receptor on the tumour cell surface leads to activation of an intracellular signalling cascade, which is important in the development and survival of solid tumours.
The EGFR gene can have mutations that cause the EGFR to be permanently activated.
Patients who have tumours that contain activating EGFR mutations are likely to respond well to EGFR tyrosine kinase inhibitors.
