Breast Oncology



Although clinical trials have shown no survival advantage and only a modest improvement in local control from adjuvant radiotherapy after lumpectomy in older women with stage I, estrogen receptor-positive (ER+) breast cancer, radiotherapy is commonly administered, raising concerns about overtreatment. Therefore, we sought to evaluate physician views on omission of radiotherapy in older women with favorable prognosis breast cancer.


We surveyed a national sample of 713 radiation oncologists and 879 surgeons. Of these, 1504 were eligible and 825 responded (55%). We assessed responses to clinical scenarios, knowledge of pertinent risk information, and correlates of views on radiotherapy omission.


Omission of radiotherapy in patients age ≥70 years with stage I, ER+ breast cancer, treated with lumpectomy and endocrine therapy, was felt to be unreasonable by 40% of surgeons and 20% of radiation oncologists. Many surgeons (29%) and radiation oncologists (10%) erroneously associated radiotherapy in older women with improvement in survival. Similarly, 32% of surgeons and 19% of radiation oncologists tended to substantially overestimate the risk of locoregional recurrence in older women with omission of RT. In a scenario with an 81-year-old with multiple comorbidities, 31% of surgeons and 35% of radiation oncologists would still recommend radiotherapy.


Many radiation oncologists and surgeons continue to consider omission of radiotherapy as substandard therapy and overestimate the benefits of radiotherapy. Surgeons, in addition to radiation oncologists, may have an opportunity to play a pivotal role in reducing overuse of aggressive care in this setting.
