About the trial

This clinical trial studies eliminating surgery and/or radiation therapy in treating breast cancer patients. In HER2 positive and triple negative breast cancers, after systemic therapy, when image-guided biopsy shows no residual cancer, patients then receive standard breast radiotherapy with no surgery. In ER positive/HER2 negative breast cancers, after endocrine therapy and ablative radiotherapy, when image-guided biopsy shows no residual cancer, patients then receive standard endocrine therapy with no surgery. For patients who have HER2 positive and triple negative breast cancers and standard surgery, after systemic therapy, breast radiotherapy is being eliminated when the pathology from surgery shows no residual cancer.
