Almonertinib is the third generation of EGFR-TKIs that has demonstrated excellent efficacy in classical mutations, however, effects in rare mutations have also been rarely reported.Here, we report a patient with advanced lung adenocarcinoma with a rare EGFR V774M/L833V compound mutation, who achieved long-lasting and stable disease control after first-line Almonertinib targeted therapy. This case report could provide more information for therapeutic strategy selecting of NSCLC patients harboring rare EGFR mutations.
