弥漫大B细胞淋巴瘤患者Ki-67蛋白表达检测的预后意义(1)
【摘要】 目的:研究弥漫大B细胞淋巴瘤(DLBCL)患者Ki-67蛋白表达检测的预后意义。方法:选取笔者所在医院2017年6月-2018年6月收治的60例弥漫大B细胞淋巴瘤患者为研究对象,均予以免疫组织化学检测法,同时检测Ki-67蛋白的表达,并予以CHOP治疗方案,观察分析Ki-67蛋白表达对患者预后的影响。结果:经检测,Ki-67蛋白低表达患者22例,Ki-67蛋白高表达患者38例。Ki-67蛋白低表达患者与Ki-67蛋白高表达患者年龄、性别、结外病变、IPL评分、LDH值、临床分期对比差异无统计学意义(P>0.05)。经过治疗后Ki-67蛋白低表达组生存时间长于Ki-67蛋白高表达组,治疗总有效率高于Ki-67蛋白高表达组,差异均有统计学意义(P<0.05)。结论:针对DLBCL可依据Ki-67蛋白表达情况评价患者的预后情况,Ki-67蛋白表达越高说明患者预后越差,故在临床上具有应用价值。

[Abstract] Objective: To investigate the prognostic significance of Ki-67 protein expression in patients with diffuse large B-cell lymphoma. Method: Sixty patients with diffuse large B-cell lymphoma (DLBCL) admitted to our hospital from June 2017 to June 2018 were enrolled in the study. Immunohistochemistry was performed to detect the expression of Ki-67 protein. The CHOP treatment protocol was also used to observe the effect of Ki-67 protein expression on the prognosis of patients. Result: After test, there were 22 patients with low expression of ki-67 protein and 38 patients with high expression of ki-67 protein. There was no significant difference in age, sex, extranodular lesion, IPL score, LDH value, clinical stage in patients with low expression of Ki-67 protein and patients with high expression of Ki-67 protein (P>0.05). After treatment, the survival time of Ki-67 protein low expression group was longer than that of Ki-67 protein high expression group, and the total effective rate of treatment was higher than that of Ki-67 protein high expression group, the differences were statistically significant (P<0.05). Conclusion: The prognosis of patients with DLBCL can be evaluated according to the expression of Ki-67 protein. The higher the expression of Ki-67 protein, the worse the prognosis of patients, so it has clinical application value.
弥漫大B细胞淋巴瘤作为临床上常见的恶性肿瘤之一,在非霍金淋巴瘤组织学类型中最为常见,且占据新诊断的病例约为32.0%[1]。DLBCL在临床表现、免疫表型、形态学等方面均具有一定的特异性,临床常用治疗多数采用蒽环类药物与利托普单抗等免疫化学疗法,尽管能够达到65%的治愈率[2],但在治疗反应和预后效果上差异较大,一些患者在治疗后易反复发作,发生肿瘤转移情况,导致治疗效果欠佳。有研究显示,Ki-67蛋白表达与DLBCL预后存在密切关系[3]。鉴于此,本次研究对DLBCL患者的Ki-67蛋白表达情况展开相应的分析,具体报道如下。
1 资料与方法
1.1 一般资料
回顾性分析笔者所在医院2017年6月-2018年6月收治的60例DLBCL患者。纳入标准:接受腹部与胸部CT检查。排除标准:在活检前均接受过相关治疗。其中男38例,女22例,年龄18~79岁,平均(52.14±3.15)岁。临床分期依据Ann Arbor分期标准原则分为Ⅰ~Ⅳ期,Ⅰ期8例,Ⅱ期26例,Ⅲ期20例,Ⅳ期6例。国际预后指数IPI评分根据NCCN标准分为Ⅰ~Ⅳ期,Ⅰ期(低危)10例,Ⅱ期(低中危)18例,Ⅲ期(高中危)20例,Ⅳ期12例(高危)。本次研究患者自愿参与且签署知情同意书,研究通过医院伦理委员会批准。
1.2 方法
入选患者均在治疗前对淋巴瘤标本进行活检,应用中性甲醛(10%)固定且包埋石蜡,应用多聚赖氨酸打胶进行免疫组织化学切片检查,厚度3 ?m,应用链霉菌抗生物素蛋白过氧化酶连结法(SP)进行免疫组化染色,实际操作依据试剂盒进行,Ki-67需先使用柠檬酸缓冲剂(ph=6.0)高压高温加热进行抗原修复处理[4-6],使用S-P法进行染色法处理。若Ki-67呈现为阳性,则表现为细胞核棕褐或棕黄色,使用×400高倍镜进行检测,并随机抽取每张切片目的视野区域5个,对阳性肿瘤細胞进行计算去平均值则为阳性占比,按照淋巴组织Ki-67蛋白阳性占比分为高表达组(占比达到40%及以上)与低表达组(占比达到40%以下)。, 百拇医药(马礼勇)
