• Oncotype DX® is likely to be cost effective compared with current clinical practice in The Netherlands.
• The assay is expected to improve survival and quality-adjusted life expectancy.
Findings
• The assay comes at an incremental costs of €1236 per patient, yielding an ICER of €11,236 per QALY gained.
• The cost–effectiveness of testing is most sensitive to variations in patient age, assay cost and net changes in
chemotherapy use in low-risk patients.
• The results of this analysis were consistent with those observed in multiple other countries.
Discussion
• Even cost-effective diagnostics face high barriers to adoption and reimbursement because their costs and
benefits fall on separate budget silos.
• Currently, neither the full benefits nor costs of effective patient stratification are fully reflected in the pricing and reimbursement systems for drugs and diagnostics.
Recommendation
• Future studies should focus on head-to-head comparisons of various assays to provide timely information for
adoption and reimbursement decisions.
