摘　　要：背景与目的:转移抑制基因KAI1/CD82在多种肿瘤的浸润、转移中起着重要的作用,但该基因与宫颈癌的关系的研究仍很不充分,因此本研究采用免疫组化方法检测宫颈鳞癌中KAI1基因的表达并探讨其临床意义。方法:采用免疫组化LSAB(Labelled streptovidin biotin staining)法检测99例宫颈鳞癌、25例宫颈上皮内瘤变穴CIN雪Ⅱ～Ⅲ级和18例正常宫颈组织中KAI1/CD82基因的表达,对检测结果与宫颈鳞癌各临床病理因素和预后的关系进行统计学分析。结果:宫颈鳞癌中KAI1阴性、弱、中、强表达依次为52.5%穴52/99雪、16.2%穴16/99雪、15.2%穴15/99雪、16.2%穴16/99雪,与正常宫颈和宫颈上皮内瘤变组相比,KAI1在宫颈鳞癌的表达存在显著下调(P=0.000)。宫颈鳞癌中KAI1表达与FIGO分期、年龄、盆腔淋巴结转移、肿瘤细胞分化程度、宫颈肌层浸润深度、血清鳞癌抗原水平、宫颈肿瘤大小、大体类型均无相关(P>0.05)。单因素和多因素分析均显示KAI1表达与宫颈鳞癌的预后无相关(P>0.05)。结论:KAI1基因在宫颈鳞癌中表达下调,但与宫颈鳞癌临床分期等一系列临床病理因素及预后均无关。BACKGROUND & OBJECTIVE: Metastasis suppressor gene KAI1/CD82 plays an important role in infiltration and metastasis of several types of human cancers, while the researches on its relation with cervical carcinoma are far from adequate now. Therefore, immunohistochemical techniques were employed in this study to determine the expression of KAI1 gene, and explore its clinical significance in cervical squamous cell carcinoma. METHODS: SP immunohistochemistry was used to detect the expression of KAI1 gene in 99 specimens of cervical squamous cell carcinoma, 25 specimens of cervical intraepithelial neoplasm (CIN) Ⅱ-Ⅲ, and 18 specimens of normal cervix. Correlations of expression of KAI1 gene to clinicopathologic factors, and prognosis of cervical squamous cell carcinoma were statistically analyzed. RESULTS: The rates of negative, weak, moderate, and strong expression of KAI1 in cervical squamous cell carcinoma were 52.5% (52/99), 16.2% (16/99), 15.2% (15/99), and 16.2% (16/99), respectively, significantly lower than those in normal cervix, and CIN Ⅱ-Ⅲ (P=0.000). Expression of KAI1 has no correlation with FIGO stage, age, pelvic lymph node metastasis, tumor histological grade, depth of cervical infiltration, serum squamous cell carcinoma antigen (SCC) level, tumor size, and gross type of cervical lesion (P>0.05). Both univariate and multivariate analyses showed expression of KAI1 has no correlation with prognosis of cervical squamous cell carcinoma (P>0.05). CONCLUSION: KAI1 gene may be an early event in development of cervical cancer, and has no correlation with prognosis of cervical squamous cell carcinoma.
