Background & aims: Prospective studies are needed to increase knowledge of fruit and vegetable consumption effects on hepatocellular carcinoma (HCC) risk. This study aimed to investigate the association between fruit and vegetable consumption and incident HCC in French patients with cirrhosis.
Methods: This study used data from a French prospective observational cohort nested in two national prospective cohorts of patients with histologically proven compensated alcohol-related or viral cirrhosis. Fruit and vegetable consumption was assessed by a trained dietitian using a semiquantitative food-frequency questionnaire validated in French and analyzed as binary exposure according to predefined thresholds (≥240 g/day for fruit or vegetables and ≥400 g/day for fruit and vegetables combined). Incident HCC was primary outcome. Propensity scores were used in Poisson regression models.
Results: Among 179 patients analyzed, 20 HCC were diagnosed during follow-up (median 7.3 [Q1-Q3: 4.1-8.0] years). A significant association was observed between HCC incidence and vegetable consumption ≥240 g/day (adjusted relative risk [RR] 0.35, 95%CI [0.13; 0.98], p = 0.04), but not with consumption of fruit and vegetable ≥400 g/day (RR = 0.49, 95%CI [0.18; 1.32], p = 0.16), nor with fruit consumption ≥240 g/day (RR = 0.80, 95% CI [0.28; 2.31], p = 0.68).
Conclusions: This longitudinal study documented insufficient fruit and/or vegetable consumption in 42.5% of patients with cirrhosis and a 65% reduction of HCC incidence in those with vegetable consumption ≥240 g/day. Reproduction of results in a larger sample are necessary to explore the potential of fruit and vegetables as protective factors in HCC.
