Real-world treatment patterns and outcomes in PD-L1-positive non-small cell lung cancer

Abstract

Aim: We report real-world treatment patterns and outcomes in patients with PD-L1+ non-small-cell lung cancer (NSCLC). Methods: This retrospective, observational study using the ConcertAI Oncology Dataset (Symphony AI, CA, USA), included patients with PD-L1+ (≥1% expression) metastatic NSCLC who began first-line (1L) treatment between 2016 and 2019. Treatment outcomes were assessed by treatment class (immune checkpoint inhibitor [ICI] monotherapy, ICI combinations or chemotherapy). Results: In total, 128 (25.5%), 237 (47.3%) and 136 patients (27.1%) received 1L chemotherapy, 1L ICI monotherapy and 1L ICI combinations, respectively. ICI combinations and monotherapy had improved clinical outcomes versus chemotherapy. Adjusted analyses showed no significant difference in outcome between ICI monotherapy and ICI combinations. Conclusion: ICI-based treatments are being increasingly adopted into clinical practice and were associated with better outcomes versus chemotherapy.
