Circulating immune complexes (CIC), complement and alpha-fetoprotein (AFP) were detected in 93 hepatitis B surface antigen (HBsAg)-positive patients with hepatocellular carcinoma (HCC), 16 patients with liver cirrhosis (LC) and 54 healthy controls. The CIC and complements were significantly higher in HCC patients than in LC patients. The complement and polyethylene glycol(PEG)-CIC in HCC patients with LC were higher than those in LC only (P less than 0.0001). The complement levels in LC patients were significantly lower than in controls. There was no difference in C3 and C4 between HCC patients and controls, while the C3 proactivator was higher in HCC patients (P less than 0.02). The C1q-CIC was higher in HCC and LC patients when compared to controls (P less than 0.0001). In patients with HCC, there was no difference in the CIC and complement levels between patients with cirrhosis and those without. There were inverse correlations between C1q-CIC and C3 (P less than 0.05), C1q-CIC and C4 (P less than 0.04). The mean level of 3% PEG-CIC and C1q-CIC increased significantly as AFP elevated, but decreased as AFP was higher than 1599 ng/ml (P less than 0.05). These results imply that CIC increase with tumor growth but further tumor burden may result in a fall in CIC, there was a shifting of CIC from complement-fixing to non-complement-fixing as AFP increased gradually.

Serum complement C3, C4, and C3 proactivator (C3PA) have been evaluated for their diagnostic power in detecting a hepatocellular carcinoma (HCC) in patients with liver cirrhosis (LC). It was found that serum complement levels were lower in LC patients than in HCC patients and that difference of the serum C4 and C3PA levels between LC patients and HCC patients were statistically significant. In addition, serum C3 PA levels were found to correlate significantly with the serum gamma-GTP levels in HCC patients. Thus, using the cutoff values of C4 and C3PA as the mean values for HCC patients, examination of serum complement levels enabled the detection of 38% of the HCC patients with low AFP levels. These findings suggest that the examination of the serum complements may be a useful a tool for the detection of HCCs in LC patients.

Serum complements, C3, C4, and C3 proactivator (C3PA), were evaluated prospectively for their diagnostic power in detecting hepatocellular carcinoma (HCC) in patients with liver cirrhosis (LC). Sixty-three LC patients, including 36 LC with HCC patients, were recruited for this study during the period from March to November 1986. The cutoff values of the complements were set according to retrospective study including 17 LC patients and 20 HCC patients. The values with highest accuracy, 75 mg/dl C3, 16 mg/dl C4, and 18 mg/dl C3PA, were selected. Based on these data, the positive predictive values, negative predictive values, and the accuracies of complements were as follows: C3, 88.9%, 85.2%, and 87.3%; C4, 93.8%, 80.6%, and 87.3%; and C3PA, 66.7%, 90.9%, and 70.9%, respectively. The accuracy elevated to 93.7% when C3, C4, and alpha-fetoprotein were combined as the diagnostic criteria. This study supports the use of complement testing as a new diagnostic tool for HCC screening in LC patients and for follow-up evaluation in posttherapy patients of LC with HCC.
