目的:探讨以表皮生长因子受体(EGFR)酪氨酸激酶抑制剂getfinibi为代表的靶向治疗晚期非小细胞肺癌(NSCLC)的可行性。方法选取2011年3月—2013年10月32例经铂类治疗方案失败的晚期 NSCLC 患者应用 getfinibi 250 mg/d治疗,采用RECIST标准评价疗效,并对接受 getfinibi 治疗的患者的肿瘤组织进行 EGFR酪氨酸激酶域基因突变检测。结果32例标本中共检测出12例基因突变。4例为19号染色体缺失突变。8例为21号染色体错义突变,均为 L858R 变异(T>G)。经getfinibi治疗后EGFR基因突变组的客观有效率达58.33%,疾病控制率达100.0%,均高于无EGFR基因突变组(分别为10.00%、20.00%)(P<0.05)。结论 getfinibi靶向治疗晚期 NSCLC 疗效明显,getfinibi治疗效果明显的患者中EGFR基因突变的发生率高,因此,EGFR酪氨酸激酶域突变检测可作为患者应用getfinibi疗效的一个预测指标。
目的:探討以錶皮生長因子受體(EGFR)酪氨痠激酶抑製劑getfinibi為代錶的靶嚮治療晚期非小細胞肺癌(NSCLC)的可行性。方法選取2011年3月—2013年10月32例經鉑類治療方案失敗的晚期 NSCLC 患者應用 getfinibi 250 mg/d治療,採用RECIST標準評價療效,併對接受 getfinibi 治療的患者的腫瘤組織進行 EGFR酪氨痠激酶域基因突變檢測。結果32例標本中共檢測齣12例基因突變。4例為19號染色體缺失突變。8例為21號染色體錯義突變,均為 L858R 變異(T>G)。經getfinibi治療後EGFR基因突變組的客觀有效率達58.33%,疾病控製率達100.0%,均高于無EGFR基因突變組(分彆為10.00%、20.00%)(P<0.05)。結論 getfinibi靶嚮治療晚期 NSCLC 療效明顯,getfinibi治療效果明顯的患者中EGFR基因突變的髮生率高,因此,EGFR酪氨痠激酶域突變檢測可作為患者應用getfinibi療效的一箇預測指標。

Objective To discuss the feasibility of targeted therapy represented by epidermal growth factor receptor (EGFR) tyro-sine kinase inhibitor getfinibi for advanced non-small cell lung cancer (NSCLC). Methods 32 cases with advanced NSCLC failed the previous platinum based chemotherapy from March 2011 to October 2013 were selected and treated by getfinibi 250 mg/d. RECIST criteria were used to evaluate the curative effect. And the EGFR tyrosine kinase domain gene mutation in the tumor tissue of the patients with getfinibi treatment was detected. Results Of the 32 cases of specimens, there were 12 cases were detected with gene mutations, including 4 cases with chromosome 19 deletion mutation, 8 cases with missense mutation of chromosome 21, all were L858R mutations (T>G). After treatment with getfinibi, the objective response rate of the EGFR gene mutation group reached 58.33%, the disease control rate reached 100.0%, higher than 10.00%, 20.00%of the non-EGFR gene mutation group, respective-ly(P<0.05). Conclusion The curative effect of getfinibi targeted therapy on advanced NSCLC is significant. And patients treated by getfinibi with a good effect have high incidence of EGFR gene mutation. Therefore, the EGFR tyrosine kinase domain gene muta-tion detection can be used as a predictive index for evaluating the curative effect of getfinibi.
