1、重庆医科大学学报2014年第39卷第1期(Journal of Chongqing Medical University 2014.Vol.39 No.1)甲状腺激素作用于全身细胞,可调节蛋白、脂类及碳水化合物代谢,对细胞生长、分化具有重要调控作用,是人体不可或缺的内分泌激素1。关于甲状腺功能与乳腺癌存在何种联系仍有争议2,且关于化疗对乳腺癌患者甲状腺功能(甲功)影响的研究较少。因此,本研究在472例乳腺疾病患者中比较了入院时乳腺恶性肿瘤患者与其他乳腺疾病患者的甲功,并探讨了化疗对甲功的影响及相邻两疗程化疗前甲功的变化。结合前期提出的内分泌激素化疗增敏疗法,即新内分泌化疗,探讨乳腺癌患者首次确

11、入2011年6月至2011年12月于我院诊治的472例女性乳腺疾病患者为研究对象,年龄1781岁,平均49岁,包括235例乳腺良性疾病患者(纤维瘤、乳腺病、脂肪瘤等)与237例乳腺癌患者(其中112例为首次确诊)。所有乳腺癌诊断均经重庆医科大学病理教研室确诊,既往明确甲状腺疾病或肝肾功异常的患者不纳入。乳腺癌化疗均按标准方案进行。1.2方法1.2.1样本及检测方法分别于入院时、化疗前及化疗后采取所有研究对象的全血送检,共910份。三碘甲状腺原氨酸(triiodothyronine,T3)、四碘甲状腺原氨酸(tetraiodothyronine,T4)、游离三碘甲状腺原氨酸(free triio
