An analysis of data on the use of radiation therapy in a large clinical trial of patients with HR+, HER2- breast cancer who had one to three involved lymph nodes and a 21-gene recurrence score of 25 or less found that rates of locoregional recurrence of the disease were low regardless of whether a patient had received regional node irradiation. The results suggest that a randomized clinical trial is required to answer the question of whether these favorable-risk patients can safely skip RNI.
In 1991, the National Breast Cancer Coalition demanded that the federal government spend $300 million more on breast cancer research. This push resulted in the creation of the Department of Defense Congressionally Directed Medical Research Program, which has broadened to 34 other diseases with an FY24 budget of $1.5 billion.
