Comparative Study
Full-dose intraoperative radiotherapy with electrons during breast-conserving surgery: experience with 590 cases.
Previous studies show that local recurrences after breast-conserving treatment occur in the site of the primary tumor. The need for postoperative radiotherapy on the whole breast is challenged in favor of radiotherapy limited to the area of the breast at high risk of recurrence. The new mobile linear accelerators easily moved close to the operating table to allow the full-dose irradiation during surgery. ⋯ ELIOT is a safe method for treating conservatively operated breasts, avoids the long period of postoperative radiotherapy, and reduces drastically the cost of radiotherapy. ELIOT reduces radiation to normal tissues and organs. Results on short-term and middle-term toxicity up to 5 years of follow-up are good. Data on local control are encouraging.
