title: [Clinical value of serum soluble Apo-1/Fas for predicting biological behaviors and prognosis of gastric carcinoma].
abstract: OBJECTIVE
  Literatures reported that the soluble Apo-1/Fas(sApo-1/Fas) levels in serum of patients with malignant carcinoma were higher than that in normal control subject, but there were fewer studies was seldom to detect the level of sApo-1/Fas in patients with malignancy carcinoma and effect of chemotherapy; the subject is to detect the level of sApo-1/Fas in patients with gastric carcinoma and effect of chemotherapy on it, and to investigate its clinical value.
  
  
  METHODS
  Enzyme linked immunosorbent assays(ELISA) was available to detect the level of sApo-1/Fas in 42 case of patients with gastric carcinoma before and after chemotherapy, as compared with 30 case of normal control subject.
  
  
  RESULTS
  Levels of sApo-1/Fas were elevated in all subgroups of patients with gastric carcinoma as compared to the controls (P < 0.01), sApo-1/Fas was correlated with clinical stage and histological grade, and not with sex, age; the sApo-1/Fas level in stage IV was higher in comparison with stage III and II (P < 0.05-0.01), and in stage III it was higher than in stage II (P < 0.05); being lower in the well differentiated and moderately differentiated than the poorly differentiated(P < 0.05-0.01), that the sApo-1/Fas levels were remarkably reduced in complete remission or partial remission patients(P < 0.01) after chemotherapy.
  
  
  CONCLUSIONS
  sApo-1/Fas may play closely reflect growth and regulation in gastric carcinoma, it may be a predictor for biological behaviors and prognosis of gastric carcinoma; sApo-1/Fas may be a new target in treating gastric carcinoma.
