摘要:

目的 探讨胃癌患者脂肪细胞因子Apelin和胰岛素受体底物-2(IRS-2)的表达与患者预后的关系。方法 选取2014年1月—2015年12月衡水市中医医院首诊胃癌患者87例。收集所有患者术后癌组织样本和近癌组织(距肿瘤边缘3 cm处的黏膜组织)样本,同时收集临床资料。检测胃癌患者癌组织和近癌组织中Apelin和IRS-2的表达情况。采用列联系数分析Apelin与IRS-2的相关性。采用Kaplan-Meier生存曲线评估胃癌患者的生存情况,采用Cox比例风险回归分析评估胃癌患者死亡的危险因素。结果 胃癌组织和近癌组织Apelin阳性表达率分别为73.56%(64/87)和5.75%(5/87),IRS-2阳性表达率分别为56.32%(49/87)和6.90%(6/87)。不同肿瘤分化程度、TNM分期和有无淋巴转移的胃癌患者之间Apelin和IRS-2阳性表达率差异均有统计学意义(P<0.05),不同性别、年龄和肿瘤大小的胃癌患者之间Apelin和IRS-2阳性表达率差异均无统计学意义(P>0.05)。列联系数分析结果显示,胃癌组织中Apelin和IRS-2表达呈弱相关性(列联系数为0.329,P=0.024)。根据Apelin和IRS-2的表达情况将胃癌患者分别分为阳性组和阴性组。Kaplan-Meier生存曲线分析结果显示,Apelin阳性组和IRS-2阳性组总生存期分别短于Apelin阴性组和IRS-2阴性组(P<0.05)。Cox比例风险回归分析结果显示,Apelin阳性、IRS-2阳性、肿瘤低分化、淋巴转移和TNM Ⅲ期均是胃癌患者死亡的危险因素[风险比(HR)值分别为3.015、2.678、2.898、2.745、3.266,95%可信区间(CI)分别为1.077~8.438、1.326~5.408、1.120~7.501、1.081~6.972、1.259~8.474]。结论 Apelin和IRS-2高表达可增加胃癌患者预后不良的风险,或可作为胃癌患者预后评估的指标。

Abstract:

Objective To investigate the relation between the expressions of adipocyte cytokine Apelin and insulin receptor substrate 2(IRS-2) and the prognosis of gastric cancer patients. Methods A total of 87 patients with gastric cancer diagnosed for the first time in Hengshui Hospital of Traditional Chinese Medicine from January 2014 to December 2015 were enrolled. Postoperative cancer tissue samples and adjacent tissue samples(mucosal tissue 3 cm away from tumor margin) of all the patients were collected,and clinical data were collected as well. The expressions of Apelin and IRS-2 in cancer tissues and adjacent tissues of patients with gastric cancer were determined. The correlation between Apelin and IRS-2 was analyzed by column correlation number. Kaplan-Meier survival curve was used to evaluate the survival of patients with gastric cancer,and Cox proportional risk regression analysis was used to evaluate the risk factors for the death of gastric cancer patients. Results The positive expression rates of Apelin were 73.56%(64/87) and 5.75%(5/87) in cancer tissues and adjacent tissues,and the positive expression rates of IRS-2 were 56.32%(49/87) and 6.90%(6/87),respectively. There was statistical significance in the positive expression rates of Apelin and IRS-2 among gastric cancer patients with different tumor differentiation degrees,TNM stages and lymphatic metastasis(P<0.05),while there was no statistical significance in the positive expression rates of Apelin and IRS-2 among gastric cancer patients with different sex,ages and tumor sizes(P>0.05). Apelin and IRS-2 expressions were weakly correlated in cancer tissues(column correlation number was 0.329,P=0.024). According to the expressions of Apelin and IRS-2,gastric cancer patients were classified into positive group and negative group. The overall survival times of Apelin positive group and IRS-2 positive group were lower than those of Apelin negative group and IRS-2 negative group,respectively(P<0.05). Positive Apelin,positive IRS-2,low tumor differentiation,lymphatic metastasis and TNM stage Ⅲ were all risk factors for death in gastric cancer patients [hazard ratios(HR) were 3.015,2.678,2.898,2.745 and 3.266,95% confidence intervals(CI)were 1.077-8.438,1.326-5.408,1.120-7.501,1.081-6.972 and 1.259-8.474,respectively]. Conclusions The high expressions of Apelin and IRS-2 may increase the risk of poor prognosis of gastric cancer patients,and they may be used as prognostic indicators of gastric cancer patients.
