摘要 目的探讨雌激素受体a亚型(ERa)、细胞周期蛋白D1(cyclinD1)在人甲状腺乳头状癌(PTC)组织中的表达及意义。方法 PTC 48例,甲状腺良性病变69例(甲状腺滤泡性腺瘤28例,结节性甲状腺肿34例,慢性淋巴细胞性甲状腺炎6例,甲状腺嗜酸细胞瘤1例),甲状腺良性病变旁正常甲状腺组织30例,用Envision免疫组化方法检测ERa、cyclinD1的表达。结果 (1)ERa在PTC中的阳性率(25%)高于在正常甲状腺组织(6.7%)和良性甲状腺病变(10.1%)中的阳性率(P<0.05),ERa表达在PTC患者的年龄、性别、淋巴结转移情况、肿瘤有无包膜侵犯间差异无统计学意义(P>0.05)。(2)cyclinD1在正常甲状腺组织中无表达,在PTC中(79.2%)的阳性率明显高于在良性甲状腺病变中的阳性率(27.5%)(P<0.05),cyclinD1的高表达与PTC患者的淋巴结转移和肿瘤包膜侵犯有关(P<0.05)。结论 (1)ERa在PTC中的表达率高于正常甲状腺组织和甲状腺良性病变组织,PTC可能为一种雌激素依赖性肿瘤。(2)cyclinD1在正常甲状腺组织中无表达,在PTC中高表达,cyclinD1的高表达与患者淋巴结转移和肿瘤包膜侵犯有关,提示患者预后不良。(3)对ERa和cyclinD1的检测,有助于预测PTC肿瘤的复发、转移风险,抗雌激素治疗和针对cyclinD1的治疗有可能成为PTC新的治疗途径之一。
