Galip Can Uyar, Medical Doctor at Etlik City Hospital, shared a post on X about a recent article by Pablo Jimenez et al. published in Journal for ImmunoTherapy of Cancer:
“Can second-event endpoints truly capture the long-term benefit of anti–PD-(L)1 therapy?
Our new systematic review and meta-analysis in the Journal for ImmunoTherapy of Cancer provides compelling evidence:
- Second-event endpoints (EFS2, PRFS2, PFS2) are strongly aligned with overall survival across anti–PD-(L)1 randomized trials.
- In both metastatic and curative-intent NSCLC, immunotherapy shows a consistent and clinically meaningful advantage (pooled HR ≈ 0.73).
- The correlation between second-event endpoints and OS is exceptionally strong (R² ≈ 0.74), reinforcing their surrogate validity for long-term outcomes.
These findings underscore a crucial insight for immuno-oncology:
Post-progression endpoints are not merely secondary—they may serve as powerful predictors of true survival benefit.”
