Study Summary

This study aims to utilize a novel biomarker-driven approach to guide neoadjuvant treatment selection. It is the hypothesis that this will improve clinical response for postmenopausal women with clinical stage II/III ER-positive, HER2-negative breast cancer and identify those who may not require neoadjuvant chemotherapy, with a primary focus on outcomes in Black patients.

Primary Outcome

* ORR is defined as patients achieving clinical complete response (CR) or partial response (PR) according to RECIST v1.1. * Complete Response (CR): disappearance of all target and non-target lesions. Residual lesions thought to be non-malignant should be further investigated before CR can be accepted. * Partial Response (PR): ≥30% decrease in the sum of measures of target lesions, taking as reference the baseline sum of diameters. Non-target lesions must be non-PD.

Interventions
