PURPOSE

To evaluate the cost-effectiveness of MRI and mammography screening strategies for women with BRCA1 gene mutations.

METHOD AND MATERIALS

Using a Markov Monte Carlo model, we compared 3 annual screening strategies versus clinical surveillance without imaging for a cohort of 25 year old BRCA1 mutation carriers: 1) Mammography, 2) MRI, 3) Combined MRI and Mammography. The model produced estimates of life expectancy (yrs), quality adjusted life expectancy (QALYs), and lifetime costs. Incremental cost-effectiveness analysis was performed to compare strategies. Input parameters were obtained from the published medical literature, existing databases, and expert opinion. Costs related to screening and diagnosis were derived from Medicare reimbursement rates. Additional costs and quality of life adjustments were derived from the published medical literature. Costs and life expectancy were discounted annually by 3%. Sensitivity analysis was performed to evaluate the effect of uncertainty in parameter estimates on results.

RESULTS

  In the base case analysis, annual combined MRI and mammography screening provided the greatest life expectancy (49.09 yrs) and quality-adjusted life expectancy (43.75 QALYs), but was also associated with the highest lifetime costs ($281,186), followed by annual MRI alone (48.99 yrs, 43.68 QALYs, $279,272), annual mammography alone (48.89 yrs, 43.59 QALYs, $270,071), and clinical surveillance without imaging (48.63 yrs, 43.46 QALYs, $264,153). The incremental cost-effectiveness ratio (ICER) for adding annual MRI to annual screening mammography was $55,575/life year gained, and $69,469/QALY gained. Results were sensitive to estimates of MRI cost and mutation penetrance, but otherwise stable across the specified parameter ranges. When the cost of a screening MRI examination increased to $883 (base case: $577), or the risk of breast cancer by age 70 fell below 29% (base case: 65%), the ICER exceeded $100,000/QALY.

CONCLUSION

For BRCA1 mutation carriers, combined annual MRI and mammography screening provides the greatest life expectancy gain and is likely cost-effective when compared with annual mammography alone.

CLINICAL RELEVANCE/APPLICATION

For BRCA1 mutation carriers, combined annual MRI and mammography screening provides the greatest life expectancy gain and is likely cost-effective when compared with annual mamm
