Meat Intake and the Risk of Hepatocellular Carcinoma: A Meta-Analysis of Observational Studies
A partir d'une revue systématique de la littérature publiée jusqu'en juin 2021 (17 études, 4 953 patients atteints d'un carcinome hépatocellulaire), cette méta-analyse évalue l'association entre une consommation de viandes (viande rouge, viande blanche, poisson, viande transformée et viande totale) et le risque de développer la maladie
The association between meat intake and hepatocellular carcinoma (HCC) risk is still unclear. We conducted a meta-analysis with observational studies to clarify this relationship. A total of 17 studies involving 2,915,680 participants and 4,953 cases of HCC were included in the meta-analysis. Ten studies reported red meat intake, nine reported white meat intake, nine reported fish intake, seven reported processed meat intake, and five reported total meat intake. The results showed that the consumption of red meat (relative risk [RR]?=?1.04; 95% confidence interval [CI]: 0.91?1.18; I2=50.50%; P?=?0.033) and total meat intake (RR = 1.01; 95% CI: 0.90?1.13; I2 = 15.50%; P?=?0.316) were not associated with risk of HCC. However, a higher dietary intake of processed meat (RR = 1.20; 95% CI: 1.02?1.41; I2 = 26.30%; P?=?0.228) may increase the risk of HCC. In contrast, the intake of white meat (RR = 0.76; 95% CI: 0.63?0.92; I2 = 68.30%; P?=?0.001) and fish (RR = 0.91; 95% CI: 0.86?0.96; I2 =40.90%; P?=?0.095) were inversely associated with risk of HCC. Our findings suggest that dietary intervention may be an effective approach to preventing HCC. These need to be verified with further well-designed observational studies and experimental clinical research.
