The aim of this study was to explore the correlation of ezrin and galectin-3 expressions with prognosis in cervical cancer. The immunohistochemical method was applied to detect ezrin and galectin-3 expressions in normal cervix tissues (n=30), cervicitis tissues (n=28), cervical intraepithelial neoplasia (CIN) tissues (classified as I-III, n=89), and cervical carcinoma tissues (n=84). Follow-up was conducted for 5 to 78 months to analyze the correlation of protein expressions with prognosis. Ezrin and galectin-3 expressions in cervical cancer were significantly higher than in normal cervix, cervicitis and CIN (all P<0.05), and expressions in CIN were significantly higher than in normal cervix and cervicitis (both P<0.05). The expressions of ezrin and galectin-3 were both related with histological grade, deep myometrial invasion and lymph node metastasis (all P<0.05). Spearman analysis showed that ezrin expression was positively correlated with galectin-3 expression in cervical cancer (r=0.355, P<0.05). The survival rate of patients with high expressions of ezrin and galectin-3 was significantly lower than those with low expressions of proteins (both P<0.05). The expressions of ezrin and galectin-3, histological grade, depth of stromal invasion, and lymph node metastasis are risk factors affecting the survival rate of patients with cervical cancer. The expressions of ezrin and galectin-3 were correlated with the development of cervical cancer, and overexpressions of those proteins were indicative of poor prognosis in patients with cervical cancer.
本研究旨在探讨埃兹蛋白(ezrin)和半乳糖凝集素-3(galectin-3)表达与宫颈癌预后的相关性。采用免疫组织化学方法检测正常宫颈组织(n = 30)、宫颈炎组织(n = 28)、宫颈上皮内瘤变(CIN,分为I - III级,n = 89)和宫颈癌组织(n = 84)中ezrin和galectin-3的表达。进行5至78个月的随访,以分析蛋白表达与预后的相关性。宫颈癌中ezrin和galectin-3的表达明显高于正常宫颈、宫颈炎和CIN(均P < 0.05),CIN中的表达明显高于正常宫颈和宫颈炎(均P < 0.05)。ezrin和galectin-3的表达均与组织学分级、肌层深部浸润和淋巴结转移有关(均P < 0.05)。Spearman分析显示,宫颈癌中ezrin表达与galectin-3表达呈正相关(r = 0.355,P < 0.05)。ezrin和galectin-3高表达患者的生存率明显低于蛋白低表达患者(均P < 0.05)。ezrin和galectin-3的表达、组织学分级、间质浸润深度和淋巴结转移是影响宫颈癌患者生存率的危险因素。ezrin和galectin-3的表达与宫颈癌的发生发展相关,这些蛋白的过表达提示宫颈癌患者预后不良。
