ObjectiveTo review the research progress of the relationship between the insulin resistance, insulin-like growth factor-Ⅰ(IGF-Ⅰ), insulin-like growth factor-Ⅱ(IGF-Ⅱ), and colorectal cancer, and to explore the future research trends.
MethodsThe related literatures in recent 5 years from abroad databases (PubMed, Web of Science, and EMBASE)and domestic databases (CNKI, WANFANG, and WEIPU)were collected and reviewed.
ResultsThe research on the correlation between the changes and colorectal cancer with insulin resistance and IGF-Ⅰand IGF-Ⅱlevels, epidemiological studies and the mechanism research, indicates that there are complex and close relationship between them.
ConclusionsThe research about the relationship between the insulin resistance, IGF-Ⅰ, IGF-Ⅱ, and colorectal cancer is promising.However, many issues need to be further investigated.
