摘要

Background

Dual inhibition of epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) pathways may improve outcomes in metastatic EGFR-mutant NSCLC, but VEGF inhibitors are not universally effective. We evaluated the impact of VEGFA and VEGFR2 expressions on EGFR-TKI outcomes.

Methods

EGFR-mutant NSCLC patients from the National Cancer Center Hospital, were retrospectively analysed. The early-stage cohort comprised stage I–IIIA patients (1997–2019). The advanced-stage cohort included metastatic patients (2018–2022). VEGFA/VEGFR2 expressions were dichotomised by median transcripts per million.

Results

Among 447 early-stage patients (median age 66), high VEGFA was associated with smoking, TP53 co-mutation, higher Brinkman Index, and higher tumour mutation burden (all p < 0.01). High VEGFA predicted shorter relapse-free survival (HR 2.10, 95% CI 1.63–2.71, p < 0.01) and overall survival (HR 2.07, 95% CI 1.46–2.95, p < 0.01). VEGFR2 expression showed no prognostic impact. In 146 relapsed patients receiving first-line EGFR-TKIs, high VEGFA was linked to shorter progression-free survival (PFS) overall (HR 1.70,95%CI 1.13-2.56, p = 0.009), particularly for first/second-generation EGFR-TKIs (HR 1.66,95%CI 1.08-2.54 p = 0.023), but not for osimertinib (p = 0.491). In 60 advanced-stage patients on osimertinib, PFS was unaffected by VEGFA (p = 0.102).

Conclusions

High VEGFA is associated with aggressive biology and inferior outcomes, correlating with shorter PFS for first/second-generation EGFR-TKIs but not for osimertinib.
