Implementation of the precision oncology program in catalonia's public health system: results, lessons learned, and future prospects

Abstract

Purpose: The Precision Oncology Program (POP) in Catalonia aims to provide equitable access to molecular testing for individuals with cancer, integrating Next-Generation Sequencing (NGS) into clinical practice to inform diagnosis, prognosis, and treatment decisions for both adult and pediatric patients with solid and hematologic malignancies, including somatic and germline alterations. This study evaluates the program's outcomes and impact. Methods: This evaluation covers the period from the program’s implementation in July 2021 through December 2023, with a more detailed analysis focusing on 2022–2023. The program involved 12 reference centers utilizing NGS technology for cancer genetic analysis, coordinated by CatSalut, the regional public health service payer. Data collected from each reference laboratory included the number of tests performed, types of tumor panels used, clinical indications, and associated outcomes. Results: Between July 2021 and December 2023, a total of 23,135 molecular tests were performed on 22,501 patients. The most frequently analyzed panels were for solid tumors (38.1%), hematologic cancers (17.3%), and germline mutations (42.2%). Pediatric patients accounted for 2.4% of the total. Notably, 24.7% of patients underwent a change in clinical management, contributing to more targeted treatment strategies, particularly in solid tumors (58.7%). Reports were delivered within an average of four weeks, meeting program benchmarks and facilitating timely decision-making. Sample submission compliance was high, reaching 98.5%. Conclusions: This POP successfully addressed operational, financial, and logistic challenges, ensuring equitable access to molecular testing. This program led to more efficient and personalized clinical management, with growing impact on cancer care and patient outcomes.
