Baseline CT radiomic and QVT features predict progression-free and overall survival in ES-SCLC patients on tarlatamab, enabling noninvasive biomarker-driven DLL3-targeted therapy selection

Baseline CT radiomic and QVT features predict progression-free and overall survival in ES-SCLC patients on tarlatamab, enabling noninvasive biomarker-driven DLL3-targeted therapy selection.,   May 27, 2026

Bispecific DLL3-targeting T-cell engagers such as tarlatamab have improved outcomes in extensive-stage small-cell lung cancer (ES-SCLC), but clinical factors and early imaging cannot distinguish transient from durable benefit.

This study evaluated whether baseline CT radiomic texture and Quantitative Vessel Tortuosity (QVT) features, combined into a radiomic risk score, predict progression-free and overall survival in 50 ES-SCLC patients receiving tarlatamab after front-line chemoimmunotherapy at Cleveland Clinic.

The score independently stratified survival, pointing to a noninvasive tool for patient selection in a setting with limited options.
