Postoperative Seroma Formation After Intraoperative Radiotherapy Using Low-Kilovoltage X-Rays Given During Breast-Conserving Surgery

Intraoperative radiotherapy with low-kilovoltage X-rays during BCS is not associated with an increased rate of palpable seroma or seroma requiring treatment. The rate of seroma formation on CT was higher after IORT compared with the NO-IORT group, which might be because of the shorter interval between BCS and CT.
