About this trial
The purpose of this study is to establish a prospective, single-center platform research based on clinical subtypes to explore precision neoadjuvant therapy in patients with operable breast cancer who met the indications for neoadjuvant chemotherapy and by the update of basic translational research in the center, especially the refinement of typing, the discovery of new targets and the development of novel targeted drugs, verified the effectiveness of new targeted drugs in neoadjuvant therapy.

Stereotactic Body Radiation Therapy (SBRT)
RadiationStereotactic Body Radiation Therapy (SBRT) is performed within 5 calendar days prior to the initiation of drug therapy. SBRT is delivered to the primary tumor in 3 fractions of 8 Gy each (total 24 Gy) over 3-5 days.

Trial outcomes
Primary outcomes
Pathological complete response rate (pCR)
Pathological complete response rate
Secondary outcomes
invasive disease-free survival (iDFS)
To determine three-year invasive disease-free survival (iDFS) among the treatment arms
Overall response rate (ORR)
Complete response (CR) + partial response (PR)
CTCAE scale (V4.0)
4\) To evaluate the rate of adverse effects of patient by the standard CTCAE scale (V4.0)

Other outcomes
Biomarker analysis
Tumor tissues, paracancerous tissues, ctDNA, blood, fecal samples, tumor pathological whole slide images and MRI images collected from study participants will be used for discovering exploratory biomarkers. The associations between these biomarkers and treatment responses disease status will be investigated.
