Abstract： 目的探讨食管癌及癌旁组织中端粒酶活性检测的意义. 方法采用 PCR技术为基础的 TRAP法检测了 39例食管癌及癌旁组织端粒酶活性. 结果 39例食管癌组织中 34例端粒酶活性阳性,阳性率为87.2%,癌旁组织中3例阳性,阳性率为7.7%,9例食管良性组织中1例阳性,阳性率为11.1%.食管癌与相应癌旁组织和良性食管组织端粒酶阳性检测率相比,差异有显著性意义(p<0. 01).伴有淋巴结转移的 25例食管癌端粒酶阳性检测率为96.0%,显著高于未伴有淋巴结转移的阳性率(71.4%),两者差异有显著性意义(p<0.05). 结论端粒酶激活与食管癌发生发展有关,对端粒酶活性进行检测对食管癌的诊断和判断预后有重要价值.
