BACKGROUND: Using data from the PACS 01 randomized trial, we evaluated the cost-effectiveness of anthracyclines plus docetaxel (Taxotere; FEC-D) versus anthracyclines alone (FEC100) in patients with node-positive breast cancer. PATIENTS AND METHODS: Costs and outcomes were assessed in 1996 patients and the incremental cost-effectiveness ratios (ICERs) were estimated, using quality-adjusted life years (QALYs) as outcome. To deal with uncertainty due to sampling fluctuations, confidence regions around the ICERs were calculated and cost-effectiveness acceptability curves were drawn up. Sensitivity analyses were also carried out to assess the robustness of conclusions. RESULTS: The mean cost of treatment was 33% higher with strategy FEC-D, but this difference decreased to 18% at a 5-year horizon. The ICER of FEC-D versus FEC100 was estimated to be 9665euro per QALY gained (95% confidence interval euro2372-euro55 515). The estimated probability that FEC-D was cost-effective reached >96% for a threshold of euro50 000 per QALY gained. If the price of taxane decreased slightly, the ICER would reach some very reasonable levels and this strategy would therefore be much more cost-effective. CONCLUSION: The sequential use of FEC100 followed by docetaxel appears to be a cost-effective alternative, even when uncertainty is taken into account.
