Real-World Data: Implementation and Outcomes of Next-Generation Sequencing in the MENA Region

Year: 2025

Type: article

Abstract: Background: In the era of precision medicine, Next-Generation Sequencing (NGS) has emerged as an important tool for identifying targetable mutations and tailoring treatment options. Yet the Middle East and North Africa (MENA) lags behind in adopting this technology. This study aims to demonstrate the transformative potential of molecular profiling in the region. Methods: This retrospective study reviewed cancer patients at the American University of Beirut Medical Centre, comparing outcomes between those who received NGS-based treatment adjustments (NBTAs) and those who did not. Results: The study enrolled 180 patients, including those with non-small-cell lung cancer (21.2%), sarcomas (20%), gastrointestinal malignancies (23.3%), breast cancer (10.6%), and other cancers (24.9%); 58.3% had stage 4 cancer at diagnosis. Before molecular profiling, 20.6% had stable disease, 21.7% showed partial response, and 57.8% had progressive disease. Most (96%) had received treatment, mainly systemic (90%), with chemotherapy (89%) being the most common. Forty patients (22.2%) underwent NGS-based treatment adjustments (NBTAs). Post-NGS, targeted therapies increased from 35% to 43% and immunotherapies from 14% to 18%. Mutations were detected in 98% of patients, with a median of four mutations per patient. NBTA patients had a median overall survival of 59 months, compared to 23 months for non-NBTA patients (p = 0.096), and significantly improved progression-free survival (5.32 vs. 3.28 months, p = 0.023). Conclusions: The use of large-scale molecular profiling to guide treatment adjustments promises advancements in patient care. Integrating NGS into clinical practice correlates with improved PFS, calling for a broader adoption of its use in the MENA region.
