Session Title:Lung Cancer - Non-small Cell Local-regional/Small Cell/Other Thoracic Cancers
Session Type:Oral Abstract Session

背景: 厄洛替尼(E)在晚期NSCLC患者中的疗效已明确,作为辅助治疗的价值有待评估。BR21研究显示EGFR阳性(IHC/FISH确诊的)的患者更能从E治疗中获益。

方法: 完全切除的ⅠB-ⅢA期NSCLC2:1随机入E(150mg,qd,连用2年)组和P(安慰剂)组。根据年龄,病理类型,之前是否行辅助化疗,吸烟史,EGFR状态和种族进行分层。主要研究终点为全分析集人群(FAS)的无病生存(DFS)。次要目的包括FAS的OS,以及含有del19/L858R突变(EGFR M+)类型的EGFR阳性患者的OS和PFS。

结果: 2007年11月至2010年7月,共随机入组973例患者。两组基线特征相似,年龄>6岁者占41%;女性41%;ⅠB期占51%,Ⅱ期33%,ⅢA期16% (AJCC第6版); 腺癌占59%;之前接受过辅助化疗者占53%;不吸烟者 20%;亚裔17%;EGFR FISH+ 72%,EGFR M+占16.5%。至2013年4月已达到进行最终DFS分析的计划有效事件数(410)。277(28%)患者死亡。中位随访时间47个月。
FAS分析,两组的DFS未达到统计学差异,分层分析中各次要研究终点也均未达到显著差异。E组中位治疗时间为12个月,P组为22个月。E组皮疹和腹泻的发生率分别为58%和52%,P组分别为17%和16%。≥3级的皮疹和腹泻发生率分别为:E组12.6%和6.2%,P组0.3%和0.3%。无药物相关的死亡事件。

结论: 厄洛替尼辅助治疗并不能延长总体患者的DFS,在EGFR M+患者中的疗效有待进一步证实。厄洛替尼在辅助治疗中的安全性与在晚期患者中观察到的一致。

JCO:不建议厄洛替尼联合贝伐单抗用于晚期NSCLC维持治疗

研究要点:1.既往研究表明,厄洛替尼联合贝伐单抗策略具有较好的耐受性及抗肿瘤活性;本研究旨在评价含贝伐单抗一线化疗后,厄洛替尼联合贝伐单抗维持治疗晚期NSCLC的潜在获益情况。2.研究表明,厄洛替尼联合贝伐单抗方案可显著改善患者PFS,但不能显著改善患者OS。3.总体而言,患者耐受性良好;维持治疗方案对生存结局影响较小,且毒性增加。在2013年10月7日在线出版的《临床肿瘤学杂志》(Journ

Lancet Oncol:化疗与厄洛替尼间插结合治疗晚期NSCLC效果良好

一项联合亚洲7个国家(地区)、28个中心的全球多中心Ⅲ期临床试验表明:与单纯采用一线化疗或口服靶向药物相比,化疗间插口服靶向药物的治疗方法将提高晚期非小细胞肺癌病人的生存期,对于有表皮生长因子受体(EGFR)基因突变的患者尤其适用。近日,该研究论文“化疗与厄洛替尼间插结合治疗晚期非小细胞肺癌的对照试验”在线发表于国际顶级刊物《柳叶刀·肿瘤学》。该研究第一作者为广东省人民医院副院长吴一龙教授。 据

ASCO 2013:香港中文大学莫树锦等证实pEGFR mut能有效预测非小细胞肺癌患者的预后

在FASTACT 2中,研究者对肿瘤生物标记物的分析证实了在晚期非小细胞肺癌患者中,EGFR突变有助于预测厄洛替尼联合化疗作为一线治疗对上述患者所带来的治疗获益。然而,在该研究中的肿瘤标本有限。最近技术的发展能够促使从不含细胞的血浆DNA中检测到EGFR突变状态(pEGFRmut)。在本研究中,研究者们旨在评估pEGFRmut和来自肿瘤组织的EGFR mut之间是否存在一定关联,同时也评估pEGF

Lancet Oncol:化疗与厄洛替尼交替可使NSCLC患者受益(FASTACT-2研究)

  广东省人民医院吴一龙教授等开展的FASTACT-2研究最新结果显示,化疗与厄洛替尼交替治疗方案可显著延长晚期非小细胞肺癌(NSCLC)患者的无进展生存期(PFS)和总生存期(OS),EGFR基因突变患者获益明显。(Lancet Oncology.2013年6月17日在线版)。  FASTACT研究为一项随机、安慰剂对照临床研究。在2009年4月29日~2010年9月9日的Ⅲ期研究中,研究者入选

Lancet Oncol:EGFR野生型NSCLC二线治疗:厄洛替尼不敌标准化疗(TAILOR研究)

厄洛替尼已经用于晚期非小细胞肺癌(NSCLC)患者的治疗。然而,对其治疗占很大比重的EGFR野生型患者的疗效仍然存在争议。因此,一项在线发表于《柳叶刀肿瘤学》(Lancet Oncology)的TAILOR研究评估了在这些EGFR野生型患者中使用厄洛替尼与标准二线化疗相比的疗效。研究内容:在意大利52家医院开展了这项随机对照试验。我们纳入EGFR野生型转移性非小细胞肺癌患者,既往接受过铂类为基础的
