Intraoperative radiotherapy during breast-conserving surgery is being studied as an alternative to 6 weeks of external beam radiotherapy (EBRT) for low-risk women; it can be delivered using electrons (intraoperative electron radiotherapy, IOERT) or 50-kV X-rays. Intraoperative radiation therapy (IORT) may pose a risk for wound complications. Between March 2018 and June 2018, 5 breast cancer patients, all eligible for breast conserving surgery (BCS), were treated at the King Saud Medical city with IORT using the IOERT. Complete data sets for age, stage (T, N, and M), and histology and hormone receptor status were available in 5 cases. Parameters to identify eligible patients are as follows: ESTRO: >50 years, invasive ductal carcinoma/other favourable histology (IDC), T1-2 (≤3 cm), N0, any hormone receptor status, M0; ASTRO: ≥60 years, IDC, T1, N0, positive estrogen hormone receptor status, M0; TARGIT E “elderly”, risk adapted radiotherapy with IORT followed by external beam radiotherapy in case of risk factors in final histopathology. Consecutive patients operated on with the same surgical technique and given IORT were included. Wound complications were evaluated.
