abstract = {Previous in vitro and case-control studies have found an
association between the insulin-like growth factor
(IGF)-axis and bladder cancer risk. Circulating
concentrations of IGF-I have also been found to be
associated with an increased risk of several cancer types;
however, the relationship between pre-diagnostic circulating
IGF-I concentrations and bladder cancer has never been
studied prospectively. We investigated the association of
pre-diagnostic plasma concentrations of IGF-I with risk of
overall bladder cancer and urothelial cell carcinoma (UCC)
in a case-control study nested within the European
Prospective Investigation into Cancer and Nutrition (EPIC)
cohort. A total of 843 men and women diagnosed with bladder
cancer between 1992 and 2005 were matched with 843 controls
by recruitment centre, sex, age at recruitment, date of
blood collection, duration of follow-up, time of day and
fasting status at blood collection using an incidence
density sampling protocol. Odds ratios (ORs) and $95\%$
confidence intervals (CIs) were calculated using conditional
logistic regression with adjustment for smoking status. No
association was found between pre-diagnostic circulating
IGF-I concentration and overall bladder cancer risk
(adjusted OR for highest versus lowest fourth: 0.91, $95\%$
CI: 0.66-1.24, ptrend = 0.40) or UCC (n of cases = 776;
0.91, 0.65-1.26, ptrend = 0.40). There was no significant
evidence of heterogeneity in the association of IGF-I with
bladder cancer risk by tumour aggressiveness, sex, smoking
status, or by time between blood collection and diagnosis
(pheterogeneity > 0.05 for all). This first prospective
study indicates no evidence of an association between plasma
IGF-I concentrations and bladder cancer risk.},
