Multicenter Trial for Eliminating Breast Cancer Surgery or Radiotherapy in Exceptional Responders to Neoadjuvant Systemic Therapy
In Brief
A clinical study evaluating Undergo EBRT, Laboratory Biomarker Analysis, and 3 other interventions for Estrogen Receptor Negative and 11 related conditions. Currently recruiting, targeting 120 participants across 8 sites.
Detailed Summary
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.
