Fasting blood glucose and cancer risk in a cohort of more than 140,000 adults in Austria.
AIMS/HYPOTHESIS: We investigated relations between fasting blood glucose and the incidence of cancer. METHODS: A population-based cohort of more than 140,000 Austrian adults (63,585 men, 77,228 women) was followed over an average of 8.4 years. Incident cancer (other than non-melanoma skin cancers) was ascertained by a population-based cancer registry (n=5,212). Cox proportional-hazards models were used to estimate hazard rate ratios (HR) stratified for age and adjusted for smoking, occupational group and body mass index. RESULTS: The highest fasting blood glucose category (>/=7.0 mmol/l) was weakly associated with all cancers combined (HR 1.20; 95% CI, 1.03-1.39 in men and 1.28; 95% CI, 1.08-1.53 in women) relative to the reference level (4.2-5.2 mmol/l). The strongest association was found for liver cancer in men (HR 4.58; 95% CI, 1.81-11.62). Positive associations between fasting hyperglycaemia (6.1-6.9 or >/=7.0 mmol/l) and cancer incidence were also observed for non-Hodgkin's lymphoma in men, and for colorectal and bladder cancer in women. Breast cancer in women diagnosed at or after age 65 was also associated with fasting blood glucose >/=7.0 mmol/l. Positive associations with glucose values >5.3 mmol/l were noted for thyroid cancer, gallbladder/bile duct cancer and multiple myeloma in men and women combined. CONCLUSIONS/INTERPRETATION: These findings provide further evidence that elevated blood glucose is associated with the incidence of several types of cancer in men and women.[1]References
