Abstract:

OBJECTIVE: To explore the expression of hypoxia inducible factor-1α (HIF-1α) in epithelial ovarian cancer and its relationship with clinical pathology,in order to understand the effect of HIF-1α in malignant biological behavior of ovarian epithelial carcinoma clear. METHODS:Original foreign literatures on the correlation between HIF-1α and epithelial ovarian cancer were selected from Cochrane Library,EMbase database,Pubmed,and Chinese original literatures were from CNKI,CBM. All analyses were performed by software STATA 11.0. Relationships between HIF-1α expression and age,pathological type,histological grade,lymph node metastasis,clinical stage were analyzed using pooled odds ratio (OR) with 95% confidence interval (CI). RESULTS:A total of 6 papers including 257 cases of epithelial ovarian cancer were analyzed. Compared with that in normal tissue,total positive rate of HIF-1αin epithelial ovarian cancer was 72.4%,which was increased significantly (OR=0.036,95%CI:0.010-0.135,P=0.000); HIF-1α was significantly correlated with lymph node metastasis and clinical stage(OR=0.080,95%CI:0.029-0.220,P=0.000; OR=0.258, 95%CI:0.136-0.490, P=0.000). Patients with positive expression of HIF-1α were prone to lymph node metastasis and advanced clinical stage. HIF-1α had no significant relation with age,pathological type and pathological grading (P>0.05). CONCLUSION:The expression of HIF-1α protein increased the risk of epithelial ovarian cancer. HIF-1α could be used as indicator of lymph node metastasis and clinical stage.
