Abstract:
Members of epidermal growth factor receptor (EGFR) or ErbB receptor family play a critical role in a wide range of human cancers. In the past decade, there has been a remarkable progress in developing ErbB targeted therapeutics. However, a substantial portion of patients has non-responsive disease or subsequently shows evidence of tumour relapse following initial success with anti-ErbB agents. Improved insights into the biology of ErbB receptor family have led to more effective second- and third-generation anti-ErbB therapies. In this review, we have summarised salient features of the ErbB receptor physiology and highlighted key mechanisms involved in abnormal ErbB signalling in tumorigenesis. The rationale of anti-ErbB receptor therapies are outlined along with key mechanisms proposed for resistance to treatment as well as the current concept of combined anti-ErbB therapies. In conclusion, improved understanding of the molecular pathways that confer resistance to anti-ErbB therapeutics will be essential in minimising tumour resistance to ErbB targeted treatments.
Insights
Targeted therapies for epidermal growth factor receptor (EGFR) or ErbB family are crucial in cancer treatment. Understanding resistance mechanisms is key to improving therapies and overcoming tumor relapse in patients receiving anti-ErbB agents.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Epidermal growth factor receptor (EGFR) and ErbB family members are critical in human cancers.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
