We aimed to investigate the associations of IGF-I, IGF-II, IGFBP-1, IGFBP-2 and IGFBP-3 concentrations with overall, aggressive and early-onset prostate cancer.Prospective analysis of biomarkers using the Endogenous Hormones, Nutritional Biomarkers and Prostate Cancer Collaborative Group dataset (up to 20 studies, 17 009 prostate cancer cases, including 2332 aggressive cases). Odds ratios (OR) and $95\%$ confidence intervals (CI) for prostate cancer were estimated using conditional logistic regression. For IGF-I, two-sample Mendelian randomization (MR) analysis was undertaken using instruments identified using UK Biobank (158 444 men) and outcome data from PRACTICAL (up to 85 554 cases, including 15 167 aggressive cases). Additionally, we used colocalization to rule out confounding by linkage disequilibrium.In observational analyses, IGF-I was positively associated with risks of overall (OR per 1 SD = 1.09: $95\%$ CI 1.07, 1.11), aggressive (1.09: 1.03, 1.16) and possibly early-onset disease (1.11: 1.00, 1.24); associations were similar in MR analyses (OR per 1 SD = 1.07: 1.00, 1.15; 1.10: 1.01, 1.20; and 1.13; 0.98, 1.30, respectively). Colocalization also indicated a shared signal for IGF-I and prostate cancer (PP4: $99\%).$ Men with higher IGF-II (1.06: 1.02, 1.11) and IGFBP-3 (1.08: 1.04, 1.11) had higher risks of overall prostate cancer, whereas higher IGFBP-1 was associated with a lower risk (0.95: 0.91, 0.99); these associations were attenuated following adjustment for IGF-I.These findings support the role of IGF-I in the development of prostate cancer, including for aggressive disease.}, keywords = {Insulin-like growth factor-I (Other) / Mendelian randomization (Other) / aggressive prostate cancer (Other) / international consortia (Other) / prospective analysis (Other) / prostate cancer (Other)}, cin = {C020}, ddc = {610}, cid = {I:(DE-He78)C020-20160331}, pnm = {313 - Krebsrisikofaktoren und Prävention (POF4-313)}, pid = {G:(DE-HGF)POF4-313}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:35726641}, doi = {10.1093/ije/dyac124}, url = {https://inrepo02.dkfz.de/record/180416}, }
