摘要
AIM: To study the relationship between Survivin and PTEN expression and lymph node metastasis, depth of invasion and prognosis of gastric cancer patients in China.METHODS: Specimens of gastric cancer tissue were collected from the Affiliated Hospital of Jianghan University. All the 140 patients had complete examination data. All lymph nodes were found by the fat-clearing method. The interrupted serial 4-micron sections, routine hematoxylin and eosin staining and immunohistochemical methods were used to detect the lymph node metastases. Gastric cancer tissue microarray was performed to test the expression of Survivin and PTEN (17A) in gastric cancer by immunohistochemical method. All data were processed using X^2 test, Fisher's exact test, Kaplan-Meyer Log-rank method and Cox multivariate analysis (SPSS 12.0 software).RESULTS: One hundred and eighteen specimens were used in our tissue microarray (utilization rate was 82.4%). A total of 7580 lymph nodes were found. Metastases were found in 90 specimens and 1618 lymph nodes were detected. The positive rate of Survivin and PTEN expression was 52.5% (62/118) and 76.2% (90/118), respectively. A highly positive correlation was found between Survivin and PTEN expression (X^2=4.17, P=0.04). Survivin expression was positively correlated with UICC N stage (X^2=8.69, P=0.03) and histological classification (X^2=4.41, P=0.04) by X^2 tests. PTEN expression was positively correlated with depth of invasion (P=0.02) and histological classification (X^2=5.47, P=0.02). But Survivin and PTEN expressions were not related with prognosis of gastric cancer patients. A significant correlation between lymph node metastasis and prognosis was demonstrated by Cox multivariate analysis (X^2=4.85, P=0.028).CONCLUSION: Survivin is positively correlated with PTEN expression in gastric cancer and is a molecular marker of lymph node metastasis while PTEN expression is a molecular marker of advanced gastric cancer. UICC N stage is the most important prognostic factor of gastric cancer in China.
瞄准:学习在 Survivin 和 PTEN 表示和淋巴节点转移之间的关系,侵略的深度和在中国的胃的癌症病人的预后。方法:胃的癌症组织的标本从 Jianghan 大学的隶属于的医院被收集。所有 140 个病人有完全的考试数据。所有淋巴结被胖空地的方法发现。染色的打断的连续 4 微米节,平淡的苏木精和曙红和免疫组织化学的方法被用来检测淋巴节点转移。胃的癌症织物微数组被执行由免疫在胃的癌症测试 Survivin 和 PTEN (17A ) 的表示组织化学的方法。所有数据多用 chi2 测试,菲希尔的准确测试, Kaplan-Meyer 木头等级方法和考克斯被处理变量分析(社会科学统计套装软体 12.0 软件) 。结果:118 个标本在我们的织物被使用微数组(利用率是 82.4%) 。7580 淋巴结的一个总数被发现。转移在 90 个标本被发现, 1618 淋巴结被检测。Survivin 和 PTEN 表示的积极的率是 52.5%(62/118 ) 并且 76.2%(90/118 ) 分别地。高度积极的关联在 Survivin 和 PTEN 表示之间被发现(chi2 = 4.17, P = 0.04 ) 。Survivin 表示断然与 UICC N 舞台被相关(chi 2 = 8.69, P = 0.03 ) 并且组织学的分类(chi2 = 4.41, P = 0.04 ) 由 chi2 测试。PTEN 表示断然与侵略的深度被相关(P = 0.02 ) 并且组织学的分类(chi2 = 5.47, P = 0.02 ) 。但是 Survivin 和 PTEN 表情没与胃的癌症病人的预后被联系。在淋巴节点转移和预后之间的重要关联被考克斯多表明变量分析(chi2 = 4.85, P = 0.028 ) 。结论:Survivin 断然在胃的癌症与 PTEN 表示被相关并且当 PTEN 表示是先进胃的癌症的一个分子的标记时,是淋巴节点转移的一个分子的标记。UICC N 舞台是在中国的胃的癌症的最重要的预示的因素。
