摘要:

目的探讨低氧诱导因子- 1α(HIF- 1α)在原发性颊黏膜鳞癌中的表达变化及其意义。方法通过免疫组织化学方法,了解HIF- 1α在60例原发性颊黏膜鳞癌中的表达,分析其阳性表达水平与颊癌临床分期、病理分级以及预后等临床病理因素之间的关系。结果不同分化程度的颊癌组织中HIF- 1α的阳性表达水平差异没有统计学意义(P>0.05);而早、晚期颊癌组织中,HIF- 1α阳性表达水平的差异存在统计学意义(P<0.05);有淋巴结转移的患者,其原发灶肿瘤组织中HIF- 1α的阳性表达水平高于无淋巴结转移者(P<0.05);预后差的颊癌组织中,HIF- 1α的阳性表达水平明显高于预后好组(P<0.05)。结论颊癌中HIF- 1α的阳性表达水平与疾病发展进程密切相关,其是颊癌患者预后不良的重要生物学指标。

Abstract:

Objective To study the expression of hypoxia inducible factor- 1α(HIF- 1α)protein in buccal carcinoma and its biological significance. Methods The expression of HIF- 1α was assayed by means of immunohistochemical technique in 60 patients. The expression of HIF- 1α and its relationship with clinical pathological factors and tumor prognosis were investigated and analyzed statistically by Kruskal-Wallis Test. Results The positive rate of HIF- 1α was higher in T3- 4 than T1- 2, and the positive rate of HIF- 1α was higher in patients with cervical lymphatic metastasis than patients without cervical lymphatic metastasis. Patients with HIF- 1αover- expression had poor prognosis than patients with HIF- 1α lower expression. Conclusion Over- expression of HIF- 1α is a vital biological marker in prognosis of buccal cancer.
