项目摘要
Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), such as gefitinib or erlotinib, are effective therapies for non-small cell lung cancer (NSCLC) patients with primary EGFR mutations. However, most patients who initially respond to treatment with these drugs will develop resistance to EGFR TKIs. A secondary EGFR T790M mutation is reported to correlate with acquired resistance. We examined the T790M mutation in primary tumors with BEAMing (beads, emulsion, amplification, magnetic), which is the most sensitive technique to detect minor mutated alleles. Currently, we can detect point mutation at the level of 1/10,000 using an improved version of the BEAMing. We detected T790M mutant alleles in NSCLCs in 20 out of 270 NSCLCs with primary EGFR mutations. The detection of small fraction of T790M mutant alleles may be useful for predicting resistance of NSCLCs to TKIs.
表皮生长因子受体 (EGFR) 酪氨酸激酶抑制剂 (TKI),例如吉非替尼或厄洛替尼,是治疗具有原发 EGFR 突变的非小细胞肺癌 (NSCLC) 患者的有效疗法。然而,大多数最初对这些药物治疗有反应的患者会产生对 EGFR TKI 的耐药性。据报道,继发性 EGFR T790M 突变与获得性耐药相关。我们使用 BEAMing(珠子、乳液、扩增、磁性)检查了原发性肿瘤中的 T790M 突变,这是检测微小突变等位基因的最灵敏的技术。目前,我们可以使用改进版本的 BEAMing 检测 1/10,000 水平的点突变。我们在 270 个具有原发性 EGFR 突变的 NSCLC 中的 20 个中检测到了 T790M 突变等位基因。小部分 T790M 突变等位基因的检测可能有助于预测 NSCLC 对 TKI 的耐药性。
