Primary Outcome Measures:
  • disease free survival [ Time Frame: 5 year ] [ Designated as safety issue: No ]
    recurrence locoregional distant metastasis Confirmed by clinical imaging or pathology

Secondary Outcome Measures:
  • breast density change [ Time Frame: 6mos, 1yr, 2yr ] [ Designated as safety issue: No ]
    breast density change measured by cumulus(mammogram) and MRI(bilateral breast MRI) imagings taken after 6mos, 1yr, 2yr after endocrine therapy initiation

Other Outcome Measures:
  • overall survival [ Time Frame: 5 year ] [ Designated as safety issue: No ]
    disease specific survival overall survival during 5yr follow up

Biospecimen Retention:   Samples With DNA

Postoperatively collected specimen (normal and cancer tissue) Preoperatively collected blood sample
