Recent developments in targeted therapies, including agents such as amivantamab, mobocertinib, and sunvozertinib, have shown promise in patients with pretreated ex20ins-positive NSCLC. No amendments were made to the registered protocol after commencement of the review. The full review protocol can be accessed on the PROSPERO database (Registration number: CRD420251056825).
Our case highlighted the feasibility of sunvozertinib neoadjuvant therapy in EGFR ex20ins-positive NSCLC patient with locally advanced disease. Importantly, adjuvant therapy using an adequate dosage of sunvozertinib is pivotal to prevent disease flare and tumor recurrence.
Furthermore, treatment with sunvozertinib did not change protein expression or subcellular localization of ABCB1. Altogether, these data demonstrate that sunvozertinib, when combined with other conventional chemotherapeutic agents, can overcome MDR and improve therapeutic effect.

EGFR exon 20ins mutations are highly heterogeneous, and different subtypes exhibit varying sensitivities to targeted drugs. Exploring individualized treatment approaches is of great clinical importance.
This regimen yielded a prolonged progression-free survival, with manageable safety and tolerability profiles. These findings demonstrated that sunvozertinib could be a promising first-line treatment option for NSCLC patients with EGFR exon 20 insertion.
