Abstract
Background: Prospective studies on insulin-like growth factor I (IGF-I) and epithelial ovarian cancer (EOC) risk are inconclusive. Data suggest risk associations vary by tumour characteristics.

Methods: We conducted a nested case–control study in the European Prospective Investigation into Cancer and Nutrition (EPIC) to evaluate IGF-I concentrations and EOC risk by tumour characteristics (n ¼ 565 cases). Multivariable conditional logistic regression models were used to estimate associations.

Results: We observed no association between IGF-I and EOC overall or by tumour characteristics.

Conclusions: In the largest prospective study to date was no association between IGF-I and EOC risk. Pre-diagnostic serum IGF-I concentrations may not influence EOC risk.
