摘要
目的探讨Kiss-1蛋白在乳腺肿瘤中的表达及其临床意义。方法用免疫组化技术检测100例乳腺癌、50例乳腺纤维腺瘤及瘤旁正常腺体Kiss-1蛋白的表达情况。结果乳腺癌及乳腺纤维腺瘤中Kiss-1的阳性率分别为60.0%(60/100)和36.0%(18/50),明显高于肿瘤周围正常腺体中阳性表达率29.0%(29/100)和14.0%(7/50,P<0.05)。Kiss-1在淋巴结阳性患者的表达率(43.6%)明显低于淋巴结阴性患者的表达率(70.5%,P=0.007)。结论Kiss-1蛋白的表达可能在抑制乳腺癌的淋巴结转移中起重要作用。
Objective To study the expression of Kiss-1 protein in breast tumor and its clinical significance. Methods The expression of Kiss-1 protein was examined by immunohistochemistry in 100 patients with breast cancer, 50 patients with fibroadenoma and their nearby normal breast tissues. Results Positive rates of Kiss-1 protein in breast cancer and breast fibroadenoma tissues were 60. 0% (60/100) and 36.0% ( 18/50), significantly higher than 29.0% (29/100) and 14.0% (7/50) positive rates in their nearby normal tissues respectively( P 〈 0. 05 ). Kiss-1 positive rate was 43. 6% in breast cancer patients with lymph node metastasis, markedly lower than 70. 5% positive rate in patients without lymph node metastasis (P = 0. 007 ). Conclusions The expression of Kiss-1 protein may play an important role in suppressing lymph nodes metastasis of breast cancer.
