摘要: 目的:检测正常子宫内膜、增生子宫内膜及子宫内膜癌中甲状腺转录因子-1(TTF-1)的表达,分析子宫内膜癌中TTF-1的表达及其与临床病理特征的关系。方法:选取11例正常子宫内膜、17例增生子宫内膜、45例子宫内膜癌组织,采用免疫组化法检测TTF-1的表达,结合临床资料进行统计分析。结果:TTF-1在正常子宫内膜、增生子宫内膜、子宫内膜癌中的阳性率分别为45%、35%、16%。与正常子宫内膜比较,子宫内膜癌中TTF-1的阳性率较低,差异有统计学意义(P<0.05);TTF-1在Ⅰ型及Ⅱ型子宫内膜癌中的表达差异无统计学意义。与高分化子宫内膜癌比较,中、低分化子宫内膜癌中的TTF-1表达明显上调(P<0.05)。TTF-1在子宫内膜癌中的表达与患者民族、年龄、手术分期、肿瘤浸润肌层深度、有无转移均无相关性。结论:TTF-1可能参与了部分子宫内膜癌的发生发展。

Abstract: Objective: To detect the expression of thyroid transcription factor-1(TTF-1) in normal endometrium, endometrial hyperplasia and endometrial carcinoma,and analyze the relationship between the TTF-1 expression and the clinical manifestation of carcinoma. Methods: The expression of TTF-1 was detected by immunohistochemistry in 11 specimens of regular endometrium, 17 specimens of endometrial hyperplasia, and 45 cases of endometrial carcinoma, and statistical analysis was performed combined with clinical data. Results:The positive rates of TTF-1 in normal endometrium, endometrial hyperplasia and endometrial carcinoma were 45%, 35% and 16%, respectively. Compared with normal endometrium, the positive rate of TTF-1 in endometrial carcinoma was lower, and the difference was statistically significant(P<0.05).There was no significant difference in the expression of TTF-1 between type Ⅰ and type Ⅱ endometrial carcinoma. Compared with highly-differentiated endometrial carcinoma, TTF-1 expression was significantly up-regulated in moderately- and poorly- differentiated endometrial carcinoma(P<0.05). The expression of TTF-1 in endometrial carcinoma was not correlated with the patient's nationality, age, clinicopathologic stage, depth of tumor invasion, and metastasis. Conclusion: TTF-1 may be involved in the occurrence and development of some endometrial carcinoma.
