Aim: Compare healthcare costs for patients with epidermal growth factor receptor mutated (EGFRm) metastatic non-small-cell lung cancer (mNSCLC) with and without progression and estimate costs of progression.Materials & methods: Retrospective claims analysis (2015-2020) from adults with EGFRm mNSCLC initiating EGFR tyrosine kinase inhibitors. Adjusted costs for 12 months were compared (with vs without progression) and cumulative costs for early versus late progression were predicted over 36 months.Results: A total of 228 patients with EGFRm mNSCLC were included. Patients with progression within 12 months incurred significantly higher total costs despite lower treatment costs (vs without progression). Medical costs were significantly higher among early versus late progressors.Conclusion: These data may aid providers aiming to administer quality care in a cost-efficient way.

Lung cancer is the leading cause of cancer death among both men and women in the US. Among US patients with adenocarcinoma histology, approximately 17% have epidermal growth factor activating mutations (EGFRm) that include exon 19 deletions or L858R mutations. These common mutations make up approximately 85% of all EGFR mutations. The aim of this study was to compare healthcare resource utilization and costs for patients with EGFRm metastatic non-small-cell lung cancer with and without disease progression within the first 12 months following first-line treatment initiation using data from insurance claims. The results suggest that patients with EGFRm metastatic non-small-cell lung cancer with disease progression in the first 12 months (after treatment initiation) have significantly higher costs compared with patients without disease progression in the first 12 months (and highest in the first 6 months). These data may help inform oncology providers aiming to administer high quality cancer care in a cost-efficient way.
