摘要 揭示垂体瘤中生长因子的生长刺激机制,为其受体拮抗剂的治疗应用提供实验依据。方法:用免疫组织化学方法研究了30例垂体瘤中EGFR及其配体EGF、TGF-α的表达。结果:大部分功能性腺瘤及所有非功能性腺瘤均有EGFR的表达,大部分腺瘤中有EGF、TGF-α表达,但它们的表达呈多相性,即免疫阳性细胞的分布疏密不一、细胞免疫染色浓淡不一、EGFR及其配体在不同瘤中的表达方式不一; 免疫组化结果与肿瘤的临床特征不相关。结论:垂体瘤中有表皮生长因子及其配体的表达,说明垂体瘤的增生存在表皮生长因子的自分泌刺激。 Objective: To explore the mechanism of growth factor autocrine stimulation in human pituitary tumors. Method: Immunohistochemical analyses of EGF. TGF-a and EGFR were studied on paraffin-embeded sections of 30 pituitary tumors. Results: Expression of EGFR and its ligand EGF. TGF-a has a variable stained cells intensity,density and type. EGFR and the ligands expressed in majority of pituitary tumors. Conclusion: The EGF autocrine stimulation exists in pituitary tumors, and tyrosine kinases inhibitors may be useful for pituitary tumors treatment.
