Thyroxine-binding globulin in elderly patients with hepatocellular carcinoma

Area of Science:

• Hepatology
• Oncology
• Endocrinology

Background:

• Elderly patients with cirrhosis and hepatocellular carcinoma (HCC) exhibit increased serum thyroxine binding globulin (TBG).
• The diagnostic significance of elevated TBG in this demographic requires further investigation.

Purpose of the Study:

• To evaluate the relevance of increased serum TBG levels in elderly patients with cirrhosis and HCC.
• To assess the combined diagnostic utility of TBG and alpha-fetoprotein (AFP) for HCC detection in aging cirrhotic patients.

Main Methods:

• Serum TBG and AFP levels were measured in three groups: healthy elderly subjects, elderly patients with cirrhosis, and elderly patients with cirrhosis and HCC.
• Statistical analysis was performed to compare marker levels across the groups.

Main Results:

• Both TBG and AFP levels were significantly higher (p < 0.01) in patients with HCC compared to healthy subjects and cirrhotic patients without HCC.
• Elevated plasma TBG in HCC patients may result from gene derepression in neoplastic hepatocytes.

Conclusions:

• Increased TBG and AFP levels show potential as biomarkers for diagnosing HCC in elderly patients with liver cirrhosis.
• TBG, in conjunction with AFP, may improve the diagnostic accuracy for HCC in this specific patient population.
