The association between fasting blood glucose and the risk of primary liver cancer in Chinese males: a population-based prospective study
Menée en Chine à partir de données portant sur 109 169 hommes inclus depuis 2006, cette étude de cohorte prospective évalue l'association entre le niveau de glycémie à jeun et le risque de cancer primitif du foie
Résumé en anglais
Background: To investigate the association between fasting blood glucose (FBG) levels and the risk of incident primary liver cancer (PLC) in Chinese males, a large prospective cohort was performed in the current study.
Methods: A total of 109 169 males participating in the routine checkups every two years were recruited in the Kailuan male cohort study since May 2006. Cox proportional hazards regression models and restricted cubic spline (RCS) were used to evaluate the association between levels of baseline FBG and the risk of incident PLC.
Results: Compared to the males with normal FBG (3.9less than or equal toFBG<6.1 mmol l−1), the males with impaired fasting glucose (IFG: 6.1less than or equal toFBG<7.0 mmol l−1) and diabetes mellitus (DM: FBG greater than or equal to7.0 mmol l−1) had a 60% (95% CI: 1.09–2.35) and a 58% (95% CI: 1.07–2.34) higher risk of incident PLC, respectively. Subgroup analysis found that IFG increased the risk of PLC among the non-smoker (HR=1.73, 95% CI: 1.01–2.98) and current alcohol drinker (HR=1.80, 95% CI: 1.03–3.16). While DM increased the risk of PLC especially among the males with normal BMI (<25 kg m−2) (HR=1.76, 95% CI: 1.05–2.94) and the HBV negativity (HR=1.89, 95% CI: 1.16–3.09), RCS analysis showed a positive non-linearly association between the FBG levels and the risk of PLC (p-overall=0.041, p-non-linear=0.049).
Conclusions: Increased FBG may be an important and potentially modifiable exposure that could have key scientific and clinical importance for preventing PLC development.
