- Abstract: Objective To investigate the efficacy of Zorifertinib in first-line treatment of patients with untreated epidermal growth factor receptor(EGFR)mutation in non-small-cell lung cancer(NSCLC)with central nervous system(CNS)metastases.Methods Two patients received Zorifertinib as first-line treatment.The response of tumor treatment was evaluated by response evaluation criteria in solid tumors version 1.1(RECEST v1.1)and RANO criteria for brain metastases(RANO-BM).Results Case 1 had EGFR exon 19del mutation and multiple brain metastases at baseline.After 51.4 months of treatment with Zorifertinib,case 1 still maintained partial response(PR)in lung lesions and complete response(CR)in intracranial lesions.Case 2 had EGFR exon 19del mutation and a single brain metastasis at baseline.Case 2 achieved PR in lung lesions and CR in intracranial lesions during the treatment with Zorifertinib.After 13.7 months,lung disease progression(PD)and new single brain metastases occurred.The comprehensive evaluation was PD.Case 1 had three-grade treatment-related adverse events(TRAEs),including dry skin,and other TRAEs were rash,abnormal liver function and diarrhea.The TRAEs were generally controllable.Conclusion Zorifertinib has a good effect on controlling intracranial and extracranial lesions in patients with EGFR-mutated NSCLC with CNS metastases.The efficacy of Zorifertinib is consistent with the EVEREST study.Zorifertinib can be one of the first-line initial treatment options.
