【佳学基因检测】Bcl-2基因检测作为肺癌生存预后因素的作用
肺癌基因检测与治疗效果评估
讨论肿瘤分子诊断与基因分析中的《肿瘤靶向药物选择的基因突变标准》,得知《Br J Cancer》在. 2003 Jul 7;89(1):55-64.发表了一篇题目为《Bcl-2作为肺癌生存预后因素的作用:通过荟萃分析对文献进行系统评价》肿瘤靶向药物治疗基因检测临床研究文章。该研究由B Martin, M Paesmans, T Berghmans, F Branle, L Ghisdal, C Mascaux, A-P Meert, E Steels, F Vallot, J-M Verdebout, J-J Lafitte, J-P Sculier等完成。促进了肺癌的正确治疗与个性化用药的发展,进一步强调了基因信息检测与分析在肺癌治疗效果预测中的重要性。

肿瘤靶向治疗基因检测临床应用结果
抗凋亡蛋白 Bcl-2 在肺癌中的作用仍存在争议。为了阐明其对小细胞和非小细胞肺癌 (NSCLC) 生存率的影响,基因解码基因检测对文献进行了系统回顾。如果试验提供了对肺癌中 Bcl-2 的独立评估并根据 Bcl-2 状态报告了生存数据分析,则选择试验进行进一步分析。为了能够汇总已发表研究的生存基因解码基因检测的研究结果,他们的基因解码基因检测的研究方法使用欧洲肺癌工作组设计的质量量表(包括研究设计、实验室基因解码基因检测的研究方法和分析)进行了评估。在 28 项研究中,11 项将 Bcl-2 表达确定为有利的预后因素,3 项将其与不良预后联系起来; 14 项试验不显着。研究之间没有检测到评分测量的差异,除了在样本量贼大的试验中发现显着更高的分数。基因解码基因检测的研究方法和实验室技术的评估独立于试验的基因解码基因检测的研究结论。共有 25 项试验,包括 3370 名患者,为荟萃分析提供了足够的信息。这些研究根据组织学、疾病阶段和实验室技术进行分类。综合风险比 (HR) 表明,阳性 Bcl-2 状态对生存有有利影响:在 I-II 期 NSCLC 的七项研究中为 0.70(95% 置信区间 0.57-0.86); 0.50 (0.39-0.65) 在八项关于手术切除的 NSCLC 的研究中; 0.91 (0.76-1.10) 在六项针对任何阶段 NSCLC 的研究中; 0.57 (0.41-0.78) 在五项关于鳞状细胞癌的研究中; 0.75 (0.61-0.93) 和 0.71 (0.61-0.83) 分别为 0.75 (0.61-0.93) 和 0.71 (0.61-0.83),五项研究通过免疫组织化学检测 Bcl-2 与 Ab 克隆 100 和 13 项研究评估 Bcl-2 与 Ab 克隆 124;四项小细胞肺癌研究为 0.92 (0.73-1.16); 1.26 (0.58-2.72) 用于三项关于神经内分泌肿瘤的研究。在 NSCLC 中,Bcl-2 表达与更好的预后相关。小细胞肺癌中 Bcl-2 表达的数据不足以评估其预后价值。
肿瘤发生与反复转移国际数据库描述:
The role of the anti-apoptotic protein Bcl-2 in lung cancer remains controversial. In order to clarify its impact on survival in small and non-small cell lung cancer (NSCLC), we performed a systematic review of the literature. Trials were selected for further analysis if they provided an independent assessment of Bcl-2 in lung cancer and reported analysis of survival data according to Bcl-2 status. To make it possible to aggregate survival results of the published studies, their methodology was assessed using a quality scale designed by the European Lung Cancer Working Party (including study design, laboratory methods and analysis). Of 28 studies, 11 identified Bcl-2 expression as a favourable prognostic factor and three linked it with poor prognosis; 14 trials were not significant. No differences in scoring measurement were detected between the studies, except that significantly higher scores were found in the trials with the largest sample sizes. Assessments of methodology and of laboratory technique were made independently of the conclusion of the trials. A total of 25 trials, comprising 3370 patients, provided sufficient information for the meta-analysis. The studies were categorised according to histology, disease stage and laboratory technique. The combined hazard ratio (HR) suggested that a positive Bcl-2 status has a favourable impact on survival: 0.70 (95% confidence interval 0.57-0.86) in seven studies on stages I-II NSCLC; 0.50 (0.39-0.65) in eight studies on surgically resected NSCLC; 0.91 (0.76-1.10) in six studies on any stage NSCLC; 0.57 (0.41-0.78) in five studies on squamous cell cancer; 0.75 (0.61-0.93) and 0.71 (0.61-0.83) respectively for five studies detecting Bcl-2 by immunohistochemistry with Ab clone 100 and for 13 studies assessing Bcl-2 with Ab clone 124; 0.92 (0.73-1.16) for four studies on small cell lung cancer; 1.26 (0.58-2.72) for three studies on neuroendocrine tumours. In NSCLC, Bcl-2 expression was associated with a better prognosis. The data on Bcl-2 expression in small cell lung cancer were insufficient to assess its prognostic value.
