简要总结
Almonertinib is a three-generation epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI), which has shown competitive potential in the second-line treatment against first-generation TKIs. This study intends to assess the efficacy and safety of stereotactic radiosurgery with sequential almonertinib in treatment-naive EGFR-mutant NSCLC patients with brain metastases.

研究组 & 干预措施
Stereotactic radiosurgery with Almonertinib
110mg Almonertinib is administered orally daily since the first day after stereotactic radiosurgery treatment (total dose 30 Gy, 5 fractions, day1, 3, 5, calibrated by CBCT before each treatment). For patients who are assessed as oligometastasis three months after Almonertinib treatment, SBRT is recommended for oligometastatic lesions
干预措施: Almonertinib (Drug)
