A Nomogram to Predict the Benefit of Radiation Therapy After Breast-Conserving Surgery in Elderly Patients with Stage I & ER-Negative, or Stage II/III Disease

摘要

Radiotherapy (RT) may be omitted for elderly (age > 70 years) breast cancer patients with favorable disease [stage I and estrogen receptor (ER)-positive with endocrine therapy]. This study sought to develop a nomogram to predict the survival benefit of RT in elderly patients with stage I & ER-negative or stage II/III (regardless of ER status) disease.
