摘要: 目的: 研究信号转导与转录活化因子3(signal transducers and activators of transcription 3, STAT3)在人喉鳞状细胞癌(简称喉癌)组织中的表达,探讨其在喉癌发生发展中的作用。 方法: 应用免疫组化SP法检测12例正常喉组织及38例喉癌组织中STAT3的阳性表达情况。 结果: STAT3阳性表达主要定位于细胞浆,STAT3蛋白在喉癌组织中的阳性细胞表达率(44.05%±13.82%)高于正常喉黏膜组织(6.40%±1.77%),其差异具有统计学意义(P<0.01)。中、低分化伴颈部淋巴结转移的喉癌组织中STAT3阳性细胞表达率显著高于高分化、无颈部淋巴结转移的喉癌组织(P<0.05)。 结论: STAT3在喉癌组织的高表达可能与喉癌的发生、发展密切相关。

Abstract: OBJECTIVE: To explore the expression and significance of signal transducers and activators of transcription 3(STAT3) in laryngeal squamous cell cancer. METHODS: Immunohistochemical technique was used to examine expression of STAT3 in 12 normal tissues and 38 laryngeal cancer. RESULTS: Positive staining of STAT3 was localized in the cytoplasm. The positive rate of STAT3 in 38 laryngeal cancer was significantly higher than those in 12 normal tissues(P<0.01). Overexpression of STAT3 protein was tested in those cancers with lymph nodes metastasis(P<0.05), and had a close relationship with histological grades(P<0.05). CONCLUSION: Overexpression of STAT3 might have a close correlation with the development of laryngeal squamous cell carcinoma.

Key words: laryngeal neoplasms, carcinoma, signal transducers and activators of transcription 3
