Takeaway

  • Individual metabolic syndrome (MetS) components showed a sex-specific linear or U-shaped association with the risk of liver cancer.

  • Central obesity and hyperglycaemia were linked to an increased risk of liver cancer in men.

Why this matters

  • Findings emphasise the significance of sex-specific liver cancer prevention strategies, particularly in patients with MetS.

Study design

  • A prospective cohort study included 474,929 participants (age, 40-69 years; 219,383 men; 256,276 women) without cancer from the UK Biobank (2006-2010).

  • Funding: Guangdong provincial Natural Science Fund project and others.

Key results

  • Of 474,929 participants, 276 incident cases of liver cancer (175 men; 101 women) were reported over a median follow-up of 6.6 years.

  • Compared with women, the risk of liver cancer was higher in men with (adjusted HR [aHR]; 95% CI):

    • MetS (1.48; 1.27-1.72; P<.001);

    • central obesity (1.62; 1.16-2.27; P<.01); and

    • hyperglycaemia:

      • pre-diabetes (1.70; 1.22-2.59; P<.05); and

      • diabetes (2.88; 1.91-4.34; P<.001).

  • High waist circumference (WC) and blood glucose had a dose-dependent association with an increased risk of liver cancer in both genders (aHR; 95% CI):

    • WC:

      • women (1.02; 1.01-1.03); and

      • men (1.02; 1.00-1.04; Pinteraction=.71).

    • blood glucose:

      • women (1.09; 0.95-1.26); and

      • men (1.19; 1.12-1.26; Pinteraction=.13).

  • U-shaped associations were seen between high-density lipoprotein (HDL) cholesterol and liver cancer in both genders and between blood pressure and liver cancer in women.

  • Low HDL cholesterol (<1.35 mmol/L) in men and high HDL cholesterol (>1.52 mmol/L) in women were associated with a higher risk of liver cancer.

Limitations

  • Observational design.
