摘要 目的研究PTEN、缺氧诱导因子(HIF)-1α和血管内皮生长因子(VEGF)在食管鳞癌组织中的表达及其临床意义。方法通过RTPCR和免疫组化的方法定量PTEN,HIF-1α和VEGF在食管癌组织中的表达情况,并研究其与病理分期的相关性。结果 PTEN和HIF-1α多存在于食管鳞癌细胞的细胞质和内皮细胞及血管细胞质中;PTEN在T0组、原位癌(Tis)组(0.178 2±0.027 1)及T1和T2组(0.168 3±0.039 7)患者中表达量比T3和T4组(0.147 0±0.052 4)患者中的表达显著增高(P<0.05),HIF-1α表达在T3+T4组中的表达量(0.233 5±0.074 8)比Tis(0.102 9±0.045 7)及T1+T2组(0.165 6±0.032 9)及T0组患者显著增高(P<0.05),HIF-1α和VEGF的变化趋势相似,PTEN的表达与HIF-1α和VEGF的表达量同样具有显著相关性(r=-0.36、-0.68,均P<0.05),HIF-1α的表达量与VEGF表达量具有显著相关性(r=0.72,P<0.05)。结论 PTEN、VEGF与HIF-1α基因在所有食管鳞癌患者组织中的表达量与肿瘤分期具有显著相关性,预示这三种蛋白的表达可能与食管鳞癌的治疗和预后具有显著关系,为开发新的抗食管癌药物、寻找新的基因治疗靶位提供理论依据,同时为临床治疗食管癌提供新的思路。
