In Vitro NSCLC EGFR-Mutant Models for Drug Sensitivity Testing

The PRECISE-EGFR study is a prospective, observational project designed to generate patient-derived in vitro models (cell cultures and organoids) from individuals with non-small cell lung cancer (NSCLC) carrying EGFR mutations. These models will be used to evaluate sensitivity to different anti-EGFR therapies and explore mechanisms of drug resistance. Using residual biological samples collected during routine clinical practice, the study will not interfere with patient care. Researchers will also compare the molecular characteristics of the models with the original tumors to ensure reliability. The overall aim is to improve precision oncology approaches, identifying the most effective treatments for specific EGFR mutation subtypes while minimizing toxicity and resistance.
