Abstract:
Objectives To investigate the correlation between HIF-1α expression level and clinical pathological characteristics of ovarian carcinoma in the elderly.Methods The expression levels of HIF-1α in normal ovary tissue,benign ovarian tumor tissue,borderline ovarian tumor tissue and ovarian cancer tissue were detected in the elderly by immunohistochemical method.And the correlations between HIF-1α expression level and clinical pathological characteristics of ovarian carcinoma were analyzed in the elderly.Results The HIF-1α expression was almost nothing in normal ovarian and benign ovarian tumor tissues,low in the borderline ovarian tissues,and high in the ovarian cancer tissue(Z=11.324,P =0.002).The IOD value of tissues was higher in borderline ovarian tumor tissue[(2.58 ± 0.65) × 105] and ovarian cancer tissue [(5.95 ± 1.02) × 105] than in normal ovary tissue[(1.90±0.35) × 105]and benign ovarian tumor tissue[1.95±0.41) × 105] (F=15.711,P=0.001).The expression of HIF-1α in the tissues was lower in ovarian cancer with stage Ⅰ-Ⅱ,high or moderate differentiation and non-metastatic lymph node than in ovarian cancer with stage Ⅲ-Ⅳ,low differentiation and metastatic lymph node (x2 =4.714,6.121,6.364;P =0.030,0.013,0.012).Conclusions The expression of HIF-1α is up-regulated in ovarian cancer in the elderly compared with normal ovarian tissues,which may be related to occurrence,development and clinical prognosis of ovarian cancer.
