摘要: 目的 探讨细胞命运决定因子(Dachshund homolog 1,DACH1)蛋白在舌鳞状细胞癌发生、发展及预后中的作用。方法 应用免疫组织化学方法检测51例舌鳞状细胞癌及其对应癌周正常组织、25例舌不典型增生组织中DACH1的表达。采用SPSS16.0软件包进行统计学处理。结果 51例舌鳞状细胞癌中,36例(70.6%)DACH1表达显著低于癌周正常组织(P<0.05);DACH1低表达与肿瘤分化差、临床分期晚及淋巴结转移相关;DACH1在舌不典型增生中的表达显著低于舌鳞癌组织(P<0.05)。单因素生存分析显示,DACH1高表达的舌癌患者,总体生存率显著高于低表达组(P<0.05)。结论 DACH1表达降低可能与舌鳞状细胞癌的发生、发展及不良预后有关,可能有助于舌癌前病变的辅助判断,并为肿瘤治疗提供潜在靶点。

Abstract: PURPOSE: To investigate the expression and role of human Dachshund homolog1(DACH1)in the development and prognosis of tongue squamous cell carcinoma(TSCC). METHODS: The expression of DACH1 was detected immunohistochemistrically in 51 samples of paraffin-embedded TSCC, paired adjacent tissues and 25 samples of atypical hyperplasia tissues of the tongue. Statistical analysis was performed using SPSS 16.0 software package. RESULTS: The results showed that 36 out of 51 TSCCs (70.6%) expressed lower levels of DACH1 compared with the paired adjacent tissues. Moreover, there was significant differences in expression of DACH1 between TSCC and paired adjacent tissues (P<0.05), and lower expression was associated with poor differentiation of tumors, advanced clinical stage and lymph node metastasis(P<0.05).In addition, the expression level of DACH1 in atypical hyperplasia tissues of tongue was also significantly lower than in tumors(P<0.05). Univariate survival analysis showed that the overall survival rate of patients with high expression of DACH1 was significantly higher than those with low expression of DACH1 (P<0.05). CONCLUSIONS: The decreased expression of DACH1 may be related to occurrence, development and poor prognosis of TSCC. It may contribute to making diagnosis for precancerous lesions in the tongue, and provide a potential effective therapeutic target for TSCC.
