【摘要】 目的 观察血管内皮生长因子(VEGF)受体(KDR)在子宫颈癌组织中的表达情况,探讨其与子宫颈癌的生长、浸润及转移的关系。方法 用免疫组织化学法检测80例子宫颈癌组织中KDR的表达情况,染色强度(-)~(+)者为KDR低表达,染色强度(+ +)者为KDR高表达。结果 在肿瘤间质血管内皮细胞中KDR的表达为,临床分期≤Ⅰb者和Ⅱa~Ⅲa者的高表达率分别为21.4%和60.6%(P<0.01);病理分化程度为高、中、低分化者的高表达率分别为7.7%、27.8%和84.1%,分别比较,差异均有极显著性(P均<0.01);5例腺癌中无一例KDR高表达,而鳞癌的高表达率为57.3%,两者比较,差异有显著性(P<0.05);有、无淋巴结转移者的高表达率分别为77.8%和46.8%,两者比较,差异有显著性(P<0.05);KDR高表达者的3年和5年生存率分别为69%和51%,显著低于KDR低表达者的95%和82%(P<0.05)。结论 KDR在子宫颈癌组织中的表达与肿瘤的生长、浸润及转移密切相关,可作为反应子宫颈癌生物学行为的指标之一。 【关键词】 受体,生长因子; 受体蛋白质酪氨酸激酶; 宫颈肿瘤

【Abstract】 Objective To observe the expression of vascular endothelial growth factor receptor (KDR)in human cervical carcinomas, to clarify the relationship between the expression and invasion, metastasis, prognostic value in human cervical carcinoma. Methods KDR was stained immunohistochemically in 80 cases of human cervical carcinoma. Results The expression of KDR in the endothelial cells of tumor vasculature is: the high KDR expression rate of clinical cancer stages ≤Ⅰb and Ⅱa~Ⅲa was 21.4% and 60.6% (P<0.01). The high KDR expression rate of the high, middle and low pathohistologic grading was 7.7%、27.8% and 84.1% respectively (P<0.01). The high KDR expression rate of adenocarcinoma and squamous-cell carcinoma was 0/5 and 57.3% (P<0.05). The high KDR expression rate of the cases with lymphonodus metastasis and without lymphonodus metastasis was 77.8% and 46.8% respectively (P<0.05). The survival rate of patients with high KDR expression tumors was significantly lower than that of patients with low KDR expression (P<0.05). Conclusion KDR is h[1] [2] 下一页 上一个医学论文: 卵巢颗粒细胞瘤预后影响因素的分析 下一个医学论文: 1380例遗传咨询患者细胞遗传学临床研究
