title: Alterations of serum cholinesterase in patients with gastric cancer.
abstract: OBJECTIVE
  To understand the correlation of serum cholinesterase (CHE) activity with gastric cancer and to assess their clinical significance.
  
  
  METHODS
  The velocity method was adopted to detect the activity of serum CHE in patients with gastric cancer and in patients with non-malignant tumor as controls.
  
  
  RESULTS
  The serum CHE activity in the treatment group was significantly lower than that in the control group with a very significant difference between the two groups (83.3:113.1,P = 0.0003). Age was significantly associated with the incidence of gastric cancer.
  
  
  CONCLUSIONS
  Serum CHE activity has a close relation with the incidence of gastric cancer.
