In the present study, we have measured the serum concentration of PIIIP in patients with various liver diseases, and studied serial changes in serum PIIIP after TAE and its gel filtration pattern in 10 cases of hepatocellular carcinoma undergone TAE.The following results were obtained. 1) Serum concentration of PIIIP was 12.3±6.1ng/ml in normal controls and elevated significantly in liver cirrhosis, liver cirrhosis with hepatocellular carcinoma, chronic active hepatitis, and acute hepatitis. 2) There was no significant difference in the serum concentrations of PIIIP between liver cirrhosis and liver cirrhosis with hepatocellular carcinoma. The result suggested that serum PIIIP cannot be a specific marker of hepatocellular carcinoma. However, the serum PIIIP concentration was decreased 2 or 4 weeks after TAE in effective cases, whereas increased in ineffective cases. Thus, the measurement of serial change in the serum PIIIP after TAE was considered to be useful for evaluating the effectiveness of TAE. 3) In analysing the elution patterns of serum PIIIP by gel chromatography, the peak of 125I-PIIIP antigen decreased 4 weeks after TAE in effective cases, whereas, no change was observed in the elution profile by gel chromatography 4 weeks after TAE in ineffective cases.These results seem to be caused by necrosis of hepatocellular carcinoma by TAE, and suggest the possibility that PIIIP is produced in hepatocellular carcinoma tissue.
