Hypertension Associated with the Risk of Extrahepatic Cancers in the Metabolic Dysfunction-associated Steatotic Liver Disease Population: A Multicenter Cross-sectional Study in China.

Abstract

Background and aims: Extrahepatic cancers have been recognized as a significant outcome of metabolic dysfunction-associated steatotic liver disease (MASLD), which involves five cardiometabolic risk factors, including hypertension, and is associated with the tumorigenesis of several cancers or with anti-cancer treatment. We aimed to investigate the association between hypertension, liver fibrosis, and extrahepatic cancers in the MASLD population.

Methods: This multicenter cross-sectional study was based on a MASLD population from hospital-based databases across 11 centers nationwide in China, according to MASLD diagnostic criteria identified using keywords and ICD-10 codes. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between risk factors and extrahepatic cancers.

Results: A total of 103,652 individuals with MASLD were identified, among whom 6,605 were diagnosed with extrahepatic cancers. The primary outcome revealed that hypertension was significantly associated with extrahepatic cancers (OR 1.14, 95% CI: 1.08-1.21), and its combination with hyperglycemia further increased this association (OR 1.36, 95% CI: 1.22-1.51). Risk factors for extrahepatic cancers included being over 40 years of age and female sex. Conversely, certain metabolism-based treatments were found to have potentially protective effects, including angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, fibrates, GLP-1 receptor agonists, and thiazolidinediones. After adjusting for confounding factors, the fibrosis-4 (FIB-4) score was associated with extrahepatic cancers. In the hypertension subgroup, FIB-4 scores of 1.30-2.66, 2.67-3.47, and ≥ 3.48 were associated with extrahepatic cancers in individuals aged 35-64 years, consistent with findings in those aged ≥ 65 years of age with FIB-4 ≥ 2.

Conclusions: Hypertension combined with liver fibrosis is associated with extrahepatic cancers in patients with MASLD.
