Objective:To observe the relativity between the expression of HIF-1α and the pathological clinical characteristics of gastric adenocarcinoma.Methods:To detect the expression of HIF-1α in the 63 normal gastric tissues and gastric adenocarcinoma using immunohistochemistry.Results:The positive rate of HIF-1α protein in gastric adenocarcinoma were apparently higher than the adjacent mucosa and normal gastric tissues(P<0.05).In gastric adenocarcinoma
along with the increase of histopathological grading
the advances of clinical staging
the metastasis of lymph node
the positive rate of HIF-1α protein increased gradually(P<0.05).Conclusion:The expression of HIF-1α were related to invasion of gastric cancer、the metastasis of lymph node、the size of the tumor.It may be taken as an index for evaluating carcinogenesis
progression
biological behaviors and prognosis of gastric carcinoma
and it may provide the way for clinical targeting treatment.
