This invention relates to a method of diagnosing can-
cerous diseases, which comprises measuring the amount of
UDP-N-acetylglucosamine:glycoprotein N-acetylglucosaminyl-
transferase in body fluid and evaluating the increase in its
amount for the diagnosis of hepatic diseases.
AFP, CEA and ?-glutamyltranspeptidase have hitherto
been used as tumor markers for the diagnosis of hepatic
cancer. But these conventional tumor markers show a pos-
itivity rate of about 60 %, making early diagnosis almost
impossible.
The method of this invention employs UDP-N-acetyl-
glucosamine:glycoprotein N-acetylglucosaminyltransferase as
tumor marker, whereby early diagnosis of hepatic cancer can
be made almost completely.
