联合检测血管内皮生长因子和核转录因子在涎腺多形性腺瘤良恶性及预后评估的价值

The clinical application of vascular endothelial growth factor and nuclear transcription factor on diagnosis and prognosis of benign and malignant salivary gland pleomorphic adenoma

目的 检测基质丰富型和细胞丰富型涎腺多形性腺瘤中血管内皮生长因子（VEGF）、核转录因子κB（NF-κB）/p50表达情况并探究其临床意义.方法 收集河北联合大学附属医院和开滦总医院2004年1月至2009年11月期间50例涎腺多形性腺瘤病理标本,其中基质丰富型涎腺多形性腺瘤25例为A组、细胞丰富型涎腺多形性腺瘤25例为B组,瘤旁正常涎腺组织25例为C组,即对照组.采用免疫组织化学技术S-P法检测VEGF、NF-κB/p50的表达情况.结果 VEGF的表达：A组153.13±60.81、B组954.65±305.79明显高于C组52.46±9.76,差异有统计学意义（P均＜0.01）,NF-κB/p50的表达：A组43.40±5.56、B组529.79±163.81明显高于C组6.83±1.90,差异有统计学意义（P均＜0.01）;B组VEGF、NF-κB/p50表达明显高于A组（P均＜0.01）;VEGF和NF-κB/p50在多形性腺瘤中表达呈正相关（r=0.9123,P=0.001）.结论 伴随着瘤体中细胞成份增多,多形性腺瘤新生血管形成能力以及细胞增殖活性逐渐升高,细胞丰富型较基质丰富型多形性腺瘤更具有恶变的倾向.

Objective To investigate the clinical application of vascular endothelial growth factor （VEGF） and nuclear transcription factor（NF-κB）/p50 on diagnosis and prognosis of the abundance of matrix and rich cell type salivary gland pleomorphic adenoma.Methods Fifty cases with parotid pleomorphic adenoma pathological from Jan.2004 to Nov.2004 collected at Affiliated Hospital of Hebei United University and Kailuan General Hospital were selected in this study.There were 25 samples with pleomorphic adenoma of matrix-based abundant salivary gland served as group A,25 samples were cell-based abundant salivary gland pleomorphic adenoma served as group B,and 25 samples were normal salivary gland tissue adjacent to tumor served as control group.The immunohistochemical technology and SP method were applied to detect the expression of VEGF and NF-κB/p50.Results Expressions of VEGF in group A and B were （153.13 ± 60.81） and （954.65 ± 305.79）,significantly higher than that in group C （52.46 ± 9.76,P 〈 0.05）.Expressions of NF-κB/p50 in group A and B were （43.40 ± 5.56）,（529.79 ± 163.81）,significantly higher in that in group C （6.83 ± 1.90,P 〈 0.05） ; Expressions of VEGF and NF-κB/p50 in group B were higher than that in group A （P 〈 0.01）.There were the positive correlation between EGF and NF-κB/p50 expression in pleomorphic adenoma samples （r =0.9123,P =0.001）.Conclusion With the increase in tumor cell components,angiogenesis and cell proliferation activity increase in cases with pleomorphic adenoma.Cases with cell-based abundant pleomorphic adenoma show the malignant transformation tendency compared with cases with matrix-based abundant pleomorohic adenoma.
