Resumen:
Introduction: 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. Method: 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.
