目的 研究雌激素受体α36(ERα36)、鸟嘌呤核苷酸交换因子(GNEF)-Vav3和存活素在人甲状腺乳头状癌(PTC)中的表达及意义。方法 选取112例癌旁正常组织为对照组,124例甲状腺乳头状癌组织为试验组,用免疫组织化学SP法检测ERα36、GNEF-Vav3和存活素的表达情况,并分析其与临床病理指标的关系和三者表达的相关性。结果 在124例PTC组织中,ERα36、GNEF-Vav3和存活素的阳性表达率分别为55.6%(69/124例)、56.5%(70/124例)和57.3%(71/124例),三者在PTC中的表达显著高于正常组织,差异有统计学意义(P〈0.001)。在有颈部淋巴结转移的PTC组织中,ERα36、GNEF-Vav3和存活素的阳性表达率分别为80.9%(55/68例)、77.9%(53/68例)和82.4%(56/68例),明显高于无淋巴结转移组织的25.0%(14/56例)、30.4%(17/56例)和26.8%(15/56例),差异有统计学意义(P〈0.001)。在TNMⅢ-Ⅳ期的PTC组织中,ERα36、GNEF-Vav3和存活素的阳性表达率分别为81.7%(49/60例)、75.0%(45/60例)和78.3%(47/60例),明显高于Ⅰ-Ⅱ期的31.3%(20/64例)、39.1%(25/64例)和37.5%(24/64例),差异有统计学意义(P〈0.001)。经Spearman等级相关分析,在124例PTC中,ERα36为78.3%(54/69例,高表达)与GNEF-Vav3为77.1%(54/70例)的阳性表达率呈显著正相关(P〈0.001);ERα36为72.5%(50/69例,高表达)与存活素为70.4%(50/71例)的阳性表达率呈显著正相关(P〈0.001);GNEF-Vav3为68.6%(48/70例)与存活素67.6%(48/71例)的阳性表达率呈显著正相关(P〈0.01)。ERα36/GNEF-Vav3、ERα36/存活素和GNEF-Vav3/存活素的这三种情况下的两种蛋白同时表达率分别为81.5%,80.0%,83.3%,这与其中仅有一种蛋白表达的48.4%,57.5%,60.0%比较,与颈部淋巴结转移的相关性更为显著,差异有统计学意义(均P〈0.05)。此外,ERα36、GNEF-Vav3和存活素的这三种蛋白联合表达率为88.9%,这与只表达一种?

英文摘要:

Objective To investigate the expression and significance of estrogen receptor - α36 ( ERα36 ), guanine nucleotide exchange factor (GNEF) -Vav3 and Survivin in human papillary thyroid carcinoma (PTC) . Methods The expression of ERot36, GNEF - Vav3 andSurvivin were analyzed with immunohistochemistry in 124 PTC samples as treatment group, and 112 normal thyroid ti- ssues were in control group. The correlations of ERα36, GNEF - Vav3 and Survivin expression with one another, and with several clinicopathological indicators were statistically analyzed. Results Positive expression rates of ERα36, GNEF -Vav3 and Survivin in 124 cases of PTC were 55.6% (69/124 cases), 56. 5% (70/124 cases), 57.3% (71/ 124 cases), respectively. In normal tissues, the positive expression rates of ERα36, GNEF- Vav3 and Survivin were 8.7% ( 10/112 cases), 1.8% (2/112 cases) and 0, which were significantly lower than those of the PTC tissues (P 〈 0. 001 ). In PTC with cervical lymph node metastasis (CLNM) , positive expression rates of ERα36, GNEF -Vav3 and Survivin were 80. 9% (55/68 cases), 77.9% ( 53/68 cases), 82.4% ( 56/68 cases) respectively, which were significantly higher than those without CLNM 25.0% ( 14/56 cases), 30.4% ( 17/56 cases), 26. 8% ( 15/56 cases) (P 〈0. 001 ). In PTC with TNM stage Ⅲ-ⅣV, positive expression rates of the three molecules were 81.7% (49/60 cases), 75.0% (45/60 cases), 78.3% (47/60 cases) respectively, which were significantly higher than those with TNM stage Ⅰ - Ⅱ 31.3% (20/64 cases), 39. 1% (25/64 cases), 37.5% (24/64 cases) (P 〈0. 001). Meanwhile, ERα36 expression of 78.3% (54/69 cases,low express), 72. 5% (50/69 cases,high express) had a positive correla- tion with GNEF - Vav3 of 77.1% (54/70 cases) and Survivin of 70. 4% (50/71 cases) ( P 〈 0. 001 ). GNEF - Vav3 of 68.6% (48/70 cases) and Survivin 67.6% (48/71 cases) expression were positively correlated (P ?
