CD44蛋白在人喉癌组织中的表达及临床意义

目的：探讨CD44在人喉癌组织中的表达及其临床意义。方法：采用免疫组织化学Envision法对261例喉不同病变组织标本进行CD44表达检测。结果：人喉癌组织中CD44高表达率为70．9％，明显高于癌前病变（16．7％）及正常喉组织（0％），其差异均有极显著性意义（P＜0．01）；喉癌组织中高分化鳞癌CD44表达明显低于低分化鳞癌（P＜0．01）；Ⅲ-Ⅳ期喉癌病变组织CD44表达明显高于I－Ⅱ期（P＜0．01）；有颈淋巴结转移的喉癌组织CD44表达明显高于无颈淋巴结转移的喉癌组织（P＜0．01）；CD44表达阳性病例3、5年生存率明显低于CD44表达阴性病例（均P＜0．05）。结论：喉癌的发生、发展及患者预后与CD44表达密切相关。

The expression of CD44 and it''''s significance in human laryngeal carcinoma

OBJECTIVE: To explore the CD44 expression in different laryngeal carcinoma tissues and their clinical significance. METHOD: Using immunohistochemistry methods to study 261 cases of archived paraffin-embedded laryngeal tissue. RESULT: The results turned out to be as follows: 1. A high level of CD44 expression was more frequently found in laryngeal carcinoma than in precarcinoma lesions and normal tissues. 2. CD44 expression correlated well with histological grades, the higher grade the lower the CD44 expression. 3. The third and fourth stages laryngeal carcinoma had stronger CD44 positive than those of the first and second stages. 4. CD44 expression in laryngeal carcinoma with cervical metastasis were higher than those without cervical metastasis. 5. To 3 and 5 years survival, CD44 positive cases had lower chance than CD44 negative cases. CONCLUSION: These results implicates that the occurrence, development and prognosis of laryngeal carcinoma may be closely related to CD44 expression.
