Experimental: Treatment Protocol
Hormonal therapy with fulvestrant 500 mg will be administered intramuscularly on days 1, 15 of the first cycle, and thereafter on day 1 of every 28-day cycle for up to 5 cycles before surgery. Docetaxel (T) 75 mg/m2 every 3 weeks will be given for four cycles. Trastuzumab (H, 8mg/kg for 1st cycle, then 6 mg/kg in subsequent cycles before and after surgery), pertuzumab (P, 840 mg for 1st cycle, then 420 mg in subsequent 3 cycles) will be given concurrently with docetaxel for a total of 4 cycles before surgery.

- Pathological Complete Remission Rate [ Time Frame: one year ]To determine pathological complete remission rate at the time of surgery in ER-positive and HER2-positive breast cancer patients undergoing neoadjuvant chemoimmunotherapy (docetaxel, trastuzumab, pertuzumab) concurrently with neoadjuvant hormonal therapy with fulvestrant. Note: pCR, defined as the absence of invasive neoplastic cells of the primary tumor in the breast, remaining in-situ lesions are allowed, ypT0-is;
- Partial Pathological Response Rate [ Time Frame: One Year ]Partial pathological response rate at the time of surgery and biomarker changes in breast cancer (biopsy vs residual tumor) before and after neoadjuvant chemotherapy Note: pPR, defined as residual invasive disease of 1cm, ypT1a-b.
- QTA (Quantitative Texture Analysis) [ Time Frame: One year ]QTA (Quantitative Texture Analysis): will be obtained from baseline mammogram and the correlation with clinical outcome after neoadjuvant therapy will be performed.
