title: Frequency of Lewis group substances in patients with cancer of stomach.
abstract: Authors examined the frequency of Lewis group substances in red blood cells (RBC) and saliva of 293 patients with cancer of stomach, and of 760 healthy volunteers. Lewis (a-b-) substances on RBC surfaces were significantly more frequent in patients with cancer of stomach compared to normal controls. Most patients with cancer of stomach who had Lewis (a-b-) type red blood cells had Lewis-a and Lewis-b substances in their saliva. The deficiency of Lea substance and the loss or weakening of Leb antigen on RBCs may be a prognostic and diagnostic indicator in patients with cancer of stomach.
