血中维生素d,血钙浓度及钙敏感受体与乳腺癌的相关性分析-correlation analysis of serum vitamin d, serum calcium concentration and calcium sensitive receptors with breast cancer
中文摘要目的:通过 检测 乳 腺 肿 瘤 患 者 血中 25- 羟基维生素 D[25-Hydroxy VitaminD, 25(OH)D] ,血钙 (Serum calcium,Ca2+) 浓 度 以 及 标 本 中 钙 敏 感 受 体 (Calcium-sensing receptor, CaSR)的表达情况,探讨它们与乳腺癌各临床病理因素 之间的关系,分析这三个指标对乳腺癌的发生、发展和预后的意义。方法:选取 63 例乳腺癌,20 例乳腺良性肿瘤和 10 例瘤旁正常腺体组织以及对应的 血清,采用免疫组织化学 S-P 法、酶联免疫法和偶氮胂Ⅲ法检测 CaSR 的表达情 况、25(OH)D 和 Ca2+浓度,分析这三个指标与乳腺癌患者年龄、是否绝经、肿瘤 大小、有无腋窝淋巴结转移、临床分期及病理类型的关系,并对 CaSR 的表达强 度和年龄﹑临床分期之间的关系进行等级相关性分析。结果:1.63 例乳腺癌组织中 CaSR 阳性 56 例(88.9%),20 例乳腺良性肿瘤组织 中 CaSR 阳性 12 例(60%),10 例瘤旁正常腺体组织中 CaSR 阳性 6 例(60%)。乳 腺癌中 CaSR 表达率与乳腺良性肿瘤、瘤旁正常腺体组织间差异均有显著性(P<0.05)。2.乳腺癌中 CaSR 的表达率与患者年龄、是否绝经、肿瘤大小、有无腋窝淋 巴结转移、临床分期和病理类型均无明显相关性(P>0.05)。CaSR 的表达强度 与年龄﹑临床分期(TNM 分期)均无明显等级相关性(P>0.05)。3.血清 25(OH)D 水平在乳腺癌组(34.13±14.14nmol/L)中明显低于乳腺良 性病组(50.29±25.65nmol/L),差异有统计学意义(P<0.05)。4.血清 25(OH)D 在淋巴结转移阳性乳腺癌患者中的水平明显低于淋巴结转 移阴性患者,差异有统计学意义(P<0.05)。25(OH)D 水平与其它临床病理因素 之间尚未发现有统计学意义(P>0.05)。5.乳腺癌患者血清钙含量与乳腺良性病组中血清钙含量无显著性差异(P>0.05)。结论:1.乳腺癌的发生可能与 CaSR 的高表达有关。2.血清 25(OH)D 水平的降低与乳腺癌的发生有一定的关系,且预后不良的25(OH)D 水平可能更低。关键词:乳腺癌;钙敏感受体(CaSR);25-羟基维生素 D [25(OH)D]Study on the correlation of breast cancer to serum level of vitamin D and calcium, expression of calcium-sensing receptorAbstractObjective:To detect serum 25-hydroxyvitamin D [25(OH)D]﹑serum calcium(Ca2+) in breast tumors and the expression of calcium-sensing receptor (CaSR) in clinical specimens, and explore the relationship between the three factors and clinicpathological factors of patients with breast cancer. The significance of 25(OH)D﹑Ca2+﹑CaSR for occurrence, development and prognosis of patients with breast cancer attempt to be achieved.Methods:CaSR were determined in 63 paraffinic tissues of patients with primary breast cancer, 20 of breast benign tumors and 10 of normal breast tissue beside tumors by immunohistochemistry S-P method as well as the concertration of serum 25(OH)Dand serum calcium by Enzyme-linked immunosorbent assay (ELISA) ﹑Tribromoarsenazo Ⅲ method. Analyze the relationship among the three factors and clinic pathological factors: age, st
