Abstract:

目的:研究宫颈癌癌前病变及其癌组织中转化生长因子Ⅱ型受体(TGFBR2)的表达及临床意义。方法:取13例慢性宫颈炎、102例宫颈上皮内瘤变和167例宫颈癌组织,构建成四块组织芯片;采用链霉卵白素-过氧化物酶连结(SP)免疫组化方法,检测四块组织芯片中TGFBR2蛋白的表达,并分析其与宫颈癌临床病理特征和预后的关系。结果:成功对11例慢性宫颈炎、97例宫颈上皮内瘤变和164例宫颈癌组织中TGFBR2蛋白的表达进行检测。在慢性宫颈炎、宫颈上皮内瘤变、宫颈癌组织中,TGFBR2蛋白的阳性表达率分别为45.5%(5/11)、20.6%(20/97)、3.0%(5/164),差异均有统计学意义(P<0.05)。TGFBR2的表达与肿瘤的FIGO分期、浸润深度及淋巴结转移密切相关,即分期越晚、浸润深度越深、伴随淋巴结转移者,TGFBR2蛋白表达水平越低(P<0.05)。随访的164例宫颈癌患者中,TGFBR2阳性和阴性患者的5年生存率分别为72.4%和69.2%,两者差异有统计学意义(P<0.05)。多因素分析显示,TGFBR2表达情况和淋巴结转移情况为影响宫颈癌预后的独立因素。结论:TGFBR2表达下降与宫颈癌发生发展过程密切相关,可作为肿瘤治疗的靶点及预后的预测指标
