【摘要】目的 观察贝伐珠单抗联合FOLFOX-6化疗方案对晚期结肠癌患者细胞凋亡及相关蛋白表达的影响。方法 选择2016年9月至2018年1月河北北方学院附属第一医院收治的晚期结肠癌患者90例为研究对象。按照随机数字表法分为观察组和对照组,每组45例。对照组患者单独使用FOLFOX-6化疗方案,观察组患者采用贝伐珠单抗联合FOLFOX-6化疗方案。分别对患者的疗效,化疗前以及化疗3个月后的肿瘤细胞凋亡指数,血清B淋巴细胞瘤2基因(Bcl-2)、环氧合酶2基因(COX-2)、人体抑癌基因p53、免抗人单克隆抗体(Bax)表达情况以及不良反应进行对比分析。结果 化疗3个月后,观察组肿瘤控制率及肿瘤细胞凋亡指数高于对照组[48.9%(22/45)比31.1%(14/45)、(4.0±1.0)比(2.7±1.0)],差异均有统计学意义(均P<0.05)。分子生物学分析显示,观察组Bcl-2阳性表达率高于对照组,COX-2、p53、Bax阳性表达率低于对照组[82.2%(37/45)比53.3%(24/45)、24.4%(11/45)比44.4%(20/45)、24.4%(11/45)比51.1%(23/45)、24.4%(11/45)比48.9%(22/45)],差异均有统计学意义(均P<0.05)。2组患者不良反应事件的发生率差异均无统计学意义(均P>0.05)。结论 贝伐珠单抗联合FOLFOX-6化疗方案对晚期结肠癌细胞凋亡有明显的促进作用,可使Bcl-2阳性率和肿瘤细胞凋亡指数明显上升,p53、Bax、COX-2阳性率下降,对于晚期结肠癌患者治疗效果良好。
【Abstract】Objective To observe the effect of bevacizumab combined with FOLFOX-6 chemotherapy on apoptosis related protein expression in advanced colon cancer patients. Methods From September 2016 to January 2018, 90 patients with advanced colon cancer in the First Affiliated Hospital of Hebei North University were randomly divided into observation group and control group, with 45 cases in each group. The control group was treated with FOLFOX-6 chemotherapy. The observation group was treated with FOLFOX-6 chemotherapy and bevacizumab. Curative effect, tumor cell apoptotic index, serum B cell lymphoma-2 gene(Bcl-2), cyclooxgenase-2 gene(COX-2), anti-oncogene p53, Bax monoclonal antibody expression and clinical side effects were analyzed before and 3 months after chemotherapy. Results After therapy, tumor control rate and cell apoptotic index in the observation group were significantly higher than those in the control group[48.9%(22/45) vs 31.1%(14/45), (4.0±1.0) vs (2.7±1.0)](P<0.05). Positive expression rate of Bcl-2 in the observation group was higher and positive expression rates of COX-2, p53 and Bax were lower than those in the control group[82.2%(37/45) vs 53.3%(24/45), 24.4%(11/45) vs 44.4%(20/45), 24.4%(11/45) vs 51.1%(23/45), 24.4%(11/45) vs 48.9%(22/45)](P<0.05). There was no significant difference of adverse event rate between the two groups(P>0.05). Conclusion Bevacizumab combined with FOLFOX-6 chemotherapy treating advanced colon cancer can effectively promote tumor cell apoptosis, increase Bcl-2 expression and reduce p53, Bax, COX-2 expression.
