The Post-operative Radiotherapy In Minimum risk Elderly (PRIME) breast cancer trial
This project estimated the impact on overall resource use of post-operative radiotherapy in women with a low risk of local recurrence of disease, and the cost-effectiveness of post-operative radiotherapy. Health care resources used by each patient in the 15 months following surgery were captured. Resource consumption was first measured in terms of physical quantities and then combined with unit cost data for the participating centres. The estimated difference in health outcomes, measured in QALYs, was close to zero whilst the costs were substantially higher in the radiotherapy arm. The probability that no-radiotherapy is cost-effective relative to radiotherapy was 94%. The magnitude of any excess local recurrence in patients not receiving radiotherapy is still uncertain.
Outcome and Translation
Breast cancer in older patients is a major and rising health care burden and radiotherapy is the standard therapy. This study added to the evidence on cost-effectiveness of radiotherapy. The follow-up was relatively short and no relapse was found. A follow-up trial (PRIME II) is currently being conducted to measure relapse more robustly within a longer follow-up (5 years). The HTA report has been downloaded over 12,000 times.
