Relationship between the recurrence of hepatocellular carcinoma (HCC) and serum alanine aminotransferase levels in hepatectomized patients with hepatitis C virus-associated cirrhosis and HCC.
BACKGROUND
The relationship between the recurrence of hepatocellular carcinoma (HCC) and the serum alanine aminotransferase (ALT) level was studied in hepatectomized patients with hepatitis C virus (HCV)-associated cirrhosis and HCC.


METHODS
Twenty-six hepatectomized patients with HCV-associated cirrhosis and HCC whose resected specimens showed neither portal vein nor hepatic vein invasion by HCC histologically were divided into 2 groups: 15 patients who had no recurrence 3 years after surgery (Group A) and 11 patients whose disease recurred 1-3 years after surgery (Group B). The patients' serum ALT levels during this period were examined.


RESULTS
In Group A, serum ALT generally showed sustained low levels < 80 international units (INU) in 12 patients (80%). In contrast, ALT levels in Group B showed several peaks or plateaus > 80 INU in all patients except 2. The recurrence rate of HCC in the hepatectomized patients with sustained low levels of ALT was 14.3% (2 of 14 patients) at 3 years, and was significantly lower (P < 0.01) than that in those patients whose ALT levels showed several peaks or plateaus > 80 INU (9 of 12 patients; 75.0%). The average level of mode of ALT in Group A (48.8 +/- 26.0 INU) was significantly smaller than that in Group B (101.1 +/- 47.3 INU) (P < 0.005).


CONCLUSIONS
The importance of hepatocytic necrosis in the recurrence of HCC in hepatectomized patients with cirrhosis and HCC of HCV origin was demonstrated and the significance of subsiding hepatic necroinflammatory process in the prevention of HCC recurrence suggested.
