ABSTRACT
Objective To explore the relationship and clinical significance of Gli1 expression in peripheral blood and cancer tissues of gastric.Method 95 gastric cancer patients were recruited as surgery group,and 40 recurrent gastric cancer patients were recruited as recurrent group.50 normal subjects were recruited as control group.Paraffin specimens of gastric cancer tissues and gastric mucosa adjacent to cancer were collected to test expression of Gli1 protein.ELISA was applied to test Gli1 in peripheral blood.Results Levels of Gli1 in peripheral blood of preoperative surgery group were higher than in control group [(9.21 ± 1.37) ng/ml vs.(0.79 ±0.18) ng/ml,t =43.193,P ＜0.001].Post-up Gli1 decreased significantly to the level of control group (t =0.722,P =0.472).Levels of Gli1 in peripheral blood of recurrent group were higher than that in preoperativesurgery group (t =14.575,P ＜ 0.001).Gli1 protein in cancer tissues was higher than that in adjacent gastric mucosa (t =33.471,P ＜0.001),and Gli1 protein in cancer tissues of surgery group was higher than that in cancer tissues of recurrent group (t =8.808,P ＜0.001).Conclusion In postoperative gastric cancer patients increased Gli1 level in peripheral blood and cancer tissues predicts recurrence.
