Background:
Multi-gene panel sequencing streamlines treatment selection for advanced non-small cell lung cancer (NSCLC). Implementation continues to be uneven across jurisdictions, partly due to uncertain clinical and economic impacts. In British Columbia (BC), Canada, the public healthcare system reimbursed a multi-gene panel in September 2016. This study determined the population-level cost-effectiveness of publicly reimbursed multi-gene panel sequencing compared to single-gene testing for advanced NSCLC.
Methods:
Our population-based retrospective study design used patient-level linked administrative health databases. We considered adult BC residents with a panel-eligible lung cancer diagnosis between September 2016 and December 2018. Using a machine learning approach, we conducted 1:1 genetic algorithm matching of recipients receiving multi-gene panel sequencing to controls receiving single-gene testing, maximising balance on observed demographic and clinical characteristics. Following matching, we estimated mean three-year survival time and costs (public healthcare payer perspective; 2021 CAD) and calculated the incremental net monetary benefit (INMB) for life-years gained (LYG) at conventional willingness-to-pay thresholds using inverse probability of censoring weighted linear regression and nonparametric bootstrapping.
Findings:
We matched 858 panel-eligible advanced NSCLC patients to controls, achieving balance for the 16 included covariates. Average test turnaround times were 18.6 days for multi-gene panel sequencing and 7.0 days for single-gene testing. After matching, mean incremental costs were $3529 (95% CI: -$4268, $10,942) and mean incremental LYG were 0.08 (95% CI: -0.04, 0.18). Among the 1000 bootstrap samples, 14.5% had lower costs and increased survival and 78.6% had higher costs and increased survival. The INMB was $523 (95% CI: -$6256, $7023) at $50,000/LYG, with a 57.5% probability of being cost-effective, and $4575 (95% CI: -$5468, $14,064) at $100,000/LYG, with an 84.0% probability of being cost-effective.
Interpretation:
Using population-based real-world data, we found a moderate to high probability that panel-based testing to inform targeted treatment for NSCLC would be cost-effective at higher thresholds.
