The tyrosine kinase signaling pathway is an important pathway for cell signal transduction, and is involved in regulating cell proliferation, cell cycle, apoptosis and other essential biological functions. Gene mutations involved in the tyrosine kinase signaling pathway often lead to the development of cancers. Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor-2 (HER2) are well known receptor tyrosine kinases (RTKs), which belong to the ERBB family and have high mutation frequency in cancers. Tyrosine kinase inhibitors (TKI) targeting EGFR and HER2 have been widely used in the clinical treatment of lung and breast cancers. However, after a period of treatment, patients will inevitably develop resistance to TKI. The insulin-like growth factor (IGF) receptor family, like the ERBB receptor family, belongs to the receptor tyrosine kinase superfamily, which also conducts an important cell signal transduction function. There is an overlap between IGF signaling and EGFR signaling in biological functions and downstream signals. In this review, we summarize the current state of knowledge of how IGF signaling interacts with EGFR signaling can influence cell resistance to EGFR/HER2-TKI. We also summarize the current drugs designed for targeting IGF signaling pathways and their research progress, including clinical trials and preclinical studies. Altogether, we aimed to discuss the future therapeutic strategies and application prospects of IGF signaling pathway targeted therapy.
