Introduction: Anaemia is a common toxicity in cancer patients and epoetins (EPOs) are now an established treatment. The economic profile of EPO treatment was assessed in patients with breast cancer treated by adjuvant-chemotherapy.
Materials and methods: Two strategies were compared: without treatment by EPO and with the possible use of treatment by EPO (epoetin alfa) when required. The clinical effectiveness criterion was time adjusted to quality of life and economic data included only direct medical costs.
Main results: One hundred ninety-two patients were included. In the group with the strategy containing the possible use of EPO, 45.5% of patients effectively received EPO. A significant difference in the haemoglobin level profile over time was observed which provided a significant overall benefit of 0.0052 (p<10(-4)) quality-adjusted life year (QALY) associated with an extra cost of <euro>1,615 (p<10(-4)). In the base case analysis, the cost per added QALY was estimated as <euro>310,577 with the strategy containing the possible use of EPO.
Conclusion: This robust result seems to be unacceptable, but the only relevant point of discussion might be the level of acceptable incremental cost-effectiveness ratio (ICER) for a patient.
