摘要
BACKGROUND, Many studies have demonstrated in animal experiments that persistent inflammation may accelerate the development of carcinoma. In this article, the question of whether the persistent elevation of serum alanine aminotransferase (ALT) levels (which represents the inflammatory necrosis of hepatocytes) correlates with die development of hepatocellular carcinoma (HCC) was studied in patients with early stage hepatitis C virus (HCV)-associated cirrhosis. METHODS. Sixty-nine consecutive patients with biopsy proven HCV-associated cirrhosis (mostly Child's Stage A) who had been followed for >5 years for the development of HCC, were studied. They were subdivided into 3 groups according to their serum ALT levels: Group A was comprised of 28 patients whose annual average serum ALT level was persistently high (greater than or equal to 80 IU) (high ALT group), Group B was comprised of 28 patients whose annual average serum ALT level was persistently low (< 80 IU) (low ALT group), and Group C was comprised of 13 unclassified patients. The patients had been studied prospectively with frequent ultrasonography and magnetic resonance imaging or computed tomography for > 5 years. RESULTS, In the high ALT group HCC developed in 71.4% of patients compared with 25.0% in the low ALT group over the observation period (P < 0.005). The 5-year rate of incidence of HCC in the high ALT group was as high as 53.6% compared with only 7.1% in the low ALT group (P < 0.001). The expected interval between the diagnosis of cirrhosis and the development of HCC was 6.0 +/- 0.7 years (mean +/- standard error) in the high ALT group and 12.7 +/- 1.2 years in the low ALT group (P < 0.001). CONCLUSIONS, The results of the current study demonstrated that the development of HCC was more rapid in the high ALT group with HCV-associated cirrhosis. Cancer 1999;86:589-95.
