Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) of the epidermal growth factor receptor (EGFR) that has been approved for the treatment of metastatic non-small cell lung cancer (NSCLC) positive for the secondary T790M mutation of EGFR. In a preclinical study, it also showed efficacy against leptomeningeal carcinomatosis (LMC) derived from NSCLC resistant to first-generation and second-generation EGFR-TKIs. We now report the case of a patient aged 70 years with symptomatic LMC derived from NSCLC with the T790M mutation of EGFR who showed a clinical and radiographic response to osimertinib.
奥希替尼是一种表皮生长因子受体(EGFR)的第三代酪氨酸激酶抑制剂(TKI),已被批准用于治疗EGFR继发性T790M突变阳性的转移性非小细胞肺癌(NSCLC)。在一项临床前研究中,它还显示出对源自对第一代和第二代EGFR-TKIs耐药的NSCLC的软脑膜癌病(LMC)有效。我们现在报告一例70岁的患者,其患有源自NSCLC且具有EGFR T790M突变的有症状LMC,该患者对奥希替尼表现出临床和影像学反应。
