Exceptional long term response to crizotinib in ROS 1‐postive advanced non small cell lung cancer

Non‐small‐cell lung cancer (NSCLC) accounts for the majority of lung cancer cases worldwide, with a significant proportion of patients harbouring actionable oncogenic alterations. Among these alterations, the ROS1 rearrangement represents a distinct subset with therapeutic implications. Here, we pre...

Zusammenfassung:Non‐small‐cell lung cancer (NSCLC) accounts for the majority of lung cancer cases worldwide, with a significant proportion of patients harbouring actionable oncogenic alterations. Among these alterations, the ROS1 rearrangement represents a distinct subset with therapeutic implications. Here, we present the case of a 52‐year‐old man diagnosed with advanced NSCLC harbouring the ROS1 fusion gene. Despite the initial poor response to conventional chemotherapy, the patient exhibited an exceptional and sustained response to crizotinib, with a progression‐free survival of 94 months and complete metabolic response on PET scan. This case underscores the importance of molecular profiling in guiding treatment decisions and highlights the efficacy of targeted therapies for ROS1‐positive NSCLC.
