The best treatment for lung cancer is still radical resection, which is indicated for stage I-II and some stage III patients, but surgery is only suitable for 20-25% of NSCLC patients. Furmonertinib is a third-generation TKI drug. Compared with first and second-generation TKI drugs, it has good benefits in the Chinese population, patients with brain metastases, and patients with 19del/L858R mutation, with better and longer-lasting effects, and can significantly improve the progression-free survival of patients. Neoadjuvant therapy can shrink the tumor, increase the rate of complete surgical resection, remove micrometastases, and reduce the risk of recurrence. Cases of patients with locally advanced (IIIA-N2) NSCLC have been reported with neoadjuvant TKI therapy, and it has been found that neoadjuvant TKI therapy can downgrade or even complete tumor remission. However, for locally advanced potentially resectable, or EGFR mutation-positive NSCLC patients with single-organ metastasis, the efficacy of third-generation EGFR-TKI combined with VEFGR inhibitor combined with targeted therapy after induction and surgery is still unclear. Limited clinical research data suggest that this new treatment mode (induction therapy-surgery-adjuvant therapy) can significantly improve the progression-free survival of patients. However, the overall survival rate under the new treatment mode and the promotion of clinical work urgently need higher-level clinical evidence to support clinical decision-making.
