胃癌组织中血管生成抑制蛋白1的表达及临床意义

Clinical significance and expression of vasohibin-1 in gastric cancer

  • 摘要: 目的 探讨血管生成抑制蛋白1(Vasohibin-1)在胃癌组织及相应癌旁组织中的表达水平,并分析其与胃癌患者临床病理特征的关系。 方法 收集2009年1月-2012年3月于锦州医科大学附属第一医院普外科行胃全切除或次全切除手术治疗且临床病理资料和随访资料完整的原发性胃癌138例的癌组织标本及对应癌旁组织标本(距癌灶5 cm以上),应用免疫组织化学SP法检测组织中Vasohibin-1的表达情况,对随访资料进行Kaplan-Meier生存分析,研究Vasohibin-1表达与胃癌病理特征的关系。 结果 Vasohibin-1在胃癌组织及癌旁组织中表达的阳性率分别为71.73%(99/138)和31.16%(43/138),差异有统计学意义(χ2=30.986,P< 0.001);Vasohibin-1蛋白在胃癌组织中的表达与癌组织的分化程度和有无淋巴结转移相关(P=0.001,P=0.005),与患者的年龄、性别、肿瘤大小、癌组织浸润深度、TNM分期无关;Log-rank检验显示Vasohibin-1蛋白阳性表达患者术后5年生存率为10%,明显低于Vasohibin-1阴性表达患者(χ2=25.185,P< 0.001)。 结论 Vasohibin-1蛋白在胃癌组织中高表达。

     

    Abstract: Objective To evaluate the expression of vasohibin-1 in gastric cancer tissue specimens and corresponding cancer adjacent tissues, analyze its clinical significance and its relationship with clinical pathological features in gastric cancer patients. Methods One hundred and thirty-eight primary gastric cancer tissue specimens and corresponding cancer adjacent tissues (away from the tumor more than 5 cm) were collected from patients with gastric cancer who had undergone total or subtotal resection with complete clinical pathological data and follow-up data in department of general surgery, the First Affiliated Hospital of Jinzhou Medical University from January 2009 to March 2012. Immunohistochemistry was used to detect the expression of vasohibin-1, follow-up data were analyzed by Kaplan-Meier survival analysis. Results The positive rate of vasohibin-1 in gastric cancer was 71.73% (99/138), and it was 31.16% (43/138) in corresponding cancer adjacent tissues with statistically significant difference (χ2=30.986, P< 0.001); The expression of vasohibin-1 in gastric cancer tissue was associated with differentiated degree and lymph node metastasis (P=0.001, P=0.005), but it was not related with patients' age, gender, tumor size, the depth of invasion and TNM staging. Log-rank test showed that the postoperative 5 years survival rate of patients with positive vasohibin-1 expression was 10%, which was significantly lower than patients with negative expression (χ2=25.185, P< 0.001). Conclusion The results suggest that vasohibin-1 expressed highly in gastric cancer.
