To assess the relationship between circulating insulin-like growth factors, particularly IGF-I, and the risks of overall, aggressive, and early-onset prostate cancer.
Collaborative pooled analysis synthesizing data across 20 prospective cohort studies.
Mendelian randomization analysis evaluating causal associations between genetically predicted insulin-like growth factor levels and prostate cancer outcomes.
Circulating IGF-I concentrations show a significant positive association with overall prostate cancer development.
Higher IGF-I levels specifically correlate with an elevated risk of aggressive prostate cancer phenotypes.

Implication

Collaborative analysis reveals circulating IGF-I increases the risk of overall and aggressive prostate cancer in men, highlighting insulin-like growth factors as potential targets.

Abstract

These findings support the role of IGF-I in the development of prostate cancer, including for aggressive disease.
