Further study details as provided by Seoul National University Hospital:

Primary Outcome Measures:
  • disease free survival [ Time Frame: 5 year ]
    recurrence locoregional distant metastasis Confirmed by clinical imaging or pathology

Secondary Outcome Measures:
  • breast density change [ Time Frame: 6mos, 1yr, 2yr ]
    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 ]
    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

Estimated Enrollment: 411
Study Start Date: January 2013
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: December 2018 (Final data collection date for primary outcome measure)
