Radiation Therapy Reduces Chances of Breast Cancer Returning in Women with Early, Hormone-Positive Disease, Trial Shows
Women with early, low-risk hormone receptor-positive breast cancer are significantly less likely to see their disease return if given radiation therapy and hormone therapy following surgery, according to a trial that followed hundreds of women for nearly 10 years. Specifically, the trial found that whole breast irradiation plus hormone therapy after breast-conserving surgery (lumpectomy) was better at controlling a tumor locally and preventing a recurrence in the same breast, compared with hormone therapy alone. The findings were revealed at ESTRO 38, the annual congress of the European Society for Radiotherapy & Oncology, held April 26–30 in Italy, in a presentation titled “Antihormones with or without irradiation in breast cancer: 10-year results of the ABCSG 8A trial.”
