摘要: Eighteen cancer patients showed high levels of CA19-9 in sera, even though the blood-group phenotypes their red blood cells were Le(a — b —). Seven these (group I) determined as —) from both and saliva consistently, whereas eleven other II) secreted either Lea or Leb antigen expression incompatible Lewis antigens. GDP-fucose: N-acetyl-glucosaminide a(1 × 4)-L-fucosyltransferase was demonstrated to be present salivas group I II. These results suggest that a cancer-associated alteration occurs patients.
