Introduction
One of the most common complications in breast conserving surgery is seroma formation. The origin of seroma formation remains unclear. While intraoperative radiotherapy (IORT) has been shown to be an alternative to whole breast irradiation, the influence on seroma production is unclear. Therefore, this analysis compares seroma production in patients with breast conserving surgery with or without IORT as tumour bed boost during breast conserving surgery.
Method
A retrospective analysis of seroma production in patients with nodal-negative (pN0sn) pT1/2 primary breast cancer treated between September 2010 and October 2013 at the Breast Cancer Centre, University Hospital Ulm was performed. Patients with neoadjuvant chemotherapy, previous breast/axillary surgery or more than one intervention were excluded. IORT was applied as a tumour bed boost with 50-kV X-rays (Intra beam®) delivering 9 Gy at the applicator surface. Seroma formation was measured using wound drains placed in breast and in axilla.
Results
Data of 152 patients (99 −IORT; 53 +IORT) were available for analysis. No significant differences between patients with or without IORT with regard to seroma production and number of days until drain removal were found (all p > 0.05).
Conclusion
Patients with IORT encountered no increased seroma production and removal of the drains was not delayed compared to patients with breast conserving surgery only. Our results indicate that IORT does not increase the seroma production compared to surgery alone.
