Precision Medicine in Action: Phase II Trial of Response Adaptive Ablative Pre-operative SPBI (RAPS) and Non-operative Sentinel Lymph Node Biopsy in Patients With Early-stage ER+ Breast Cancer: RAPS Trial
University of Texas Southwestern Medical Center
Summary
1\. Efficacy of PULSAR preoperative radiation 2. Evaluate potential of microbubble CEUS as an alternative to operative SLNBx 3. Evaluate potential of OA to evaluate treatment response of pre-operative radiation on the tumor

Inclusion Criteria: * 1\. Invasive epithelial (ductal, medullary, lobular, papillary, mucinous (colloid), or tubular) histologies of the breast 3 cm or less(T1-T2cN0) in women who have not undergone surgery or neoadjuvant endocrine or chemotherapy for current breast cancer diagnosis. For cohort 1, it is highly recommended those tumors are at least 1 cm. 2\. Tumor must not involve the overlying skin based on imaging evaluation and/or clinical exam 3.

Interventions
- RadiationRadiomics on MRI
Through extracting and analyzing a large number of features from medical imaging, radiomics has shown promising results in treatment outcome prediction for many diseases including breast cancer (45-50). UTSW physics group has developed several new radiomic approaches and radiomic features, such as a multi-objective radiomics model(51) and a new radiomic "Shell" feature(52). As an exploratory end point for this trial, the investigators will explore the application radiomics using pre-treatment MRI, treatment parameters and clinical characteristics as input to predict pathological response of radiation therapy (XRT) based on pathology report of surgical tissues and local recurrence.
