title: [Accelerated partial breast irradiation with multicatheters during breast conserving surgery for cancer].
abstract: BACKGROUND
  Accelerated partial breast irradiation (APBI) with multicatheters after lumpectomy for breast cancer (BC) may be an alternative to whole breast irradiation in selected patients. The aim is to show our 5 year experience.
  
  
  METHODS
  Between June 2007 and June 2012, 87 BC patients have been evaluated for APBI. Inclusion criteria were: age over 40 years, unifocal tumour, infiltrating ductal or intraductal carcinoma, tumour size smaller than 3 cm and no lymph node involvement. Complications, cosmetic results and local and distant recurrences were evaluated.
  
  
  RESULTS
  Treatment was completed in 48 patients and contraindicated in 39. The average age of treated patients was 59 years. Operating time was 123 min with 9 implanted catheters in each patient. No complications were observed during surgery or radiotherapy. Patients were discharged from hospital after 4 days. Tumour size was 11 mm. Of these, 35 were infiltrating ductal and 13 intraductal carcinomas. A total of 44 patients received adjuvant treatment. Mean follow-up was 22 months with no evidence of local or distant recurrence. The cosmetic outcome was good or excellent in 66% of cases.
  
  
  CONCLUSIONS
  APBI with multicatheter placed after lumpectomy for BC is feasible and safe but requires a strict selection of patients.
