One hundred and fifty-three consecutive cases of HCC and 25 controls from autopsy material were studied by immunohistochemical method in this paper. A review of the histopathology and demonstration of AFP. alpha- 1-antichymotrypsin (AACT), alpha-1-antitrypsin (AAT) and CEA were made.
Among the tumor markers, AACT yielded the highest positive rate, 109 cases (71%) out of 153 HCC. CEA was the next, 95 cases (62%). AFP and AAT gave the same result, 72 cases (47%). AACT, AAT and CEA were not found in the controls. AFP was present in a few hepatocytes in 1 of 25 controls. The results were in keeping with serum tests so far as the highest positive rate being AACT was concerned. Therefore, combined determination of AACT and AFP would seem a better screening method than by that of AFP alone for survey of HCC.
