PURPOSE: Since accelerated partial breast irradiation has demonstrated non-inferiority to whole breast irradiation regarding recurrence rate in patients with early stage breast cancer, our objective was to compare its impact on short-term adverse events, patient satisfaction and costs.
MATERIALS AND METHODS: Patients with early stage breast cancer treated by breast-conserving surgery between 2007 and 2012 were included: 48 women who received three-dimensional conformal accelerated partial breast irradiation in a multicentre phase-II trial were paired with 48 patients prospectively treated with whole breast irradiation. Adverse events, and patients' opinions concerning cosmesis, satisfaction and pain, were gathered 1 month after treatment. Direct and indirect costs were collected from the French National Health Insurance System perspective until the end of radiotherapy.
RESULTS: When comparing its impact, skin reactions occurred in 37% of patients receiving three-dimensional conformal accelerated partial breast radiotherapy and 60% of patients receiving whole breast irradiation (P=0.07); 98% were very satisfied in the group three-dimensional conformal accelerated partial breast radiotherapy versus 46% in the group treated with whole breast irradiation (P<0.001); direct costs were significantly lower in the group treated with partial breast irradiation (mean cost: 2510€ versus 5479€/patient), due to less radiation sessions.
CONCLUSION: In patients with early-stage breast cancer, partial irradiation offered a good alternative to whole breast irradiation, as it was less expensive and satisfactory. These, and the clinical safety and tolerance results, need to be confirmed by long-term accelerated partial breast irradiation results in on-going phase III trials.
