根据最近的研究发现,我们如何能改进鳞状NSCLC患者的治疗选择?
We read with interest the results of the HARMONi-6 trial by Zhiwei Chen and colleagues,1 which showed that ivonescimab plus chemotherapy improved progression-free survival versus tislelizumab plus chemotherapy in advanced squamous non-small-cell lung cancer (NSCLC). However, PD-L1-based subgroup results reveal a critical stratification signal. In patients with PD-L1 tumour proportion score (TPS) of under 50%, dual blockade achieved marked benefit (hazard ratio [HR] 0·63; 95% CI 0·41–0·98), whereas in patients with PD-L1 TPS of 50% or over, the improvement was numerical but not significant (HR 0·71; 0·37–1·33)

The results of the HARMONi-6 trial raise important questions about our current understanding of biomarkers in NSCLC. We need to discuss whether PD-L1 TPS should be the primary determinant in treatment decisions or if other factors should also be considered.

We should explore how the insights from the HARMONi-6 trial can be integrated into existing treatment frameworks for squamous NSCLC. This includes considering how patient demographics and health characteristics influence treatment effectiveness.

While the HARMONi-6 trial shows promise, relying solely on PD-L1 TPS for treatment strategies could oversimplify the complexities of squamous NSCLC. We must ensure that clinical guidelines do not prematurely favor one treatment over another, as individual patient responses can vary widely.
