摘要
目的 探讨人端粒酶逆转录酶 (HTERT)在鼻咽癌中的表达水平及其临床意义。方法 用免疫组化法检测HTERT在鼻咽癌、鼻咽粘膜上皮非典型增生组织及鼻咽慢性炎性黏膜中的表达 ,结合临床TNM分期、淋巴结及远处转移情况以及预后生存期等进行分析。结果 ⑴鼻咽癌组织HTERT的阳性率为 83 4% (70 /84) ,鼻咽粘膜上皮非典型增生组织及慢性炎性黏膜组织HTERT的阳性率均为 0 0 % (0 /8及 0 /16) (P <0 0 1) ;⑵鼻咽癌临床TNM分期组间HTERT定性表达率存在显著差异 (P <0 0 5 ) ;有鼻咽癌淋巴结转移的患者 ,其HTERT的阳性表达强度明显增加 (P <0 0 5 ) ;远处转移组间HTERT的阳性表达率及表达强度均未发现显著差异 (P >0 0 5 ) ;⑶HTERT阳性组中位生存期低于阴性组中位生存期 ,两者间存在显著性差异 (P <0 0 5 )。结论 HTERT可作为临床诊断鼻咽癌的一个潜在指标 ,且对预测临床分期。
Objective This study was designed to investigate the expression of human telmerase reverse transcriptase (HTERT) in nasopharyngeal carcinoma (NPC) and its clinical significance.Methods Expression of HTERT in NPC and dysplasia of nasopharyngeal epithelium and chronic inflammation of nasopharyngeal epithelium were determined by immunocytochemical staining.The results were analysed,compared with the clinical TNM stage ,lymph node metastasis ,other places metastasis and prognostic survivals of the NPC patients.Results Positive rate of HTERT in NPC was 83 7%(70/84),while positive rate of HTERT in dysplasia of nasopharyngeal epithelium and chronic inflammation of nasopharyngeal epithelium both were 0 0%(0/8 and 0/16) (P<0 01),there are significant differences for HTERT in positive rate of clinical TNM stage group and for HTERT in positive intensity of lymph node metastasis group (P<0 05). But no significant difference for HTERT expression were observed in NPC patients of other places matastasis group (P>0 05).The median survival of HTERT positive group was shorter than the nagative one.Conclusions Expression of HTERT may be a potential marker for clinical diagnosis of NPC and may has significance in predicting clinical TNM stage, metastasis and prognostic survival of the NPC patients.
