Comparison of alpha-1-antitrypsin and alpha-1-antichymotrypsin in hepatocellular carcinoma: an immunoperoxidase study.


Alpha-1-antitrypsin (A1AT) has been shown to be a useful tumor marker for hepatocellular carcinoma (HCC) and some other neoplasms. No studies of alpha-1-antichymotrypsin (A1AChy) in HCC have been reported. A comparative study of A1AT and A1AChy in HCC was undertaken. While 19/33 HCC were positive for A1AT, all 33 HCC contained immunoreactive A1AChy. Cells… (More)
