We reported a case of aumolertinib for treating an advanced NSCLC patient with rare complex mutations of EGFR exon20 V774M/S768I….Two months post-radiotherapy, disease progression was observed in both the lung and brain. Based on the disease progression, aumolertinib was administered in combination with the anti-angiogenic drug anlotinib, resulting in stable disease(SD). The PFS1 of aumolertinib monotherapy was approximately 11 months.... Importantly, this case is the first report of aumolertinib being applied to EGFR V774M/S768I mutations (monotherapy PFS: 11 months), providing meaningful insight into potential regimens for patients harboring these complex mutations.
