Treatment: Other: polymorphism analysis
SNPs will be genotyped in whole blood samples taken at baseline.

Other interventions: laboratory biomarker analysis
Biomarkers will be assessed in blood and serum samples at different time points.

Treatment: Surgery: quality-of-life assessment
Quality of life will be assessed using the Breast Cancer Prevention Trial (BCPT) Symptom Scales and the IBCSG Trial 35-07 QL Form.

Outcomes
Primary outcome [1] 0 0
Levels of Estrone (E1), Estradiol (E2), and Estrone Sulphate (E1S) Among Patients in the Longitudinal Analysis Population
Timepoint [1] 0 0
0 (baseline), 9, 10.5, and 12 months from randomization
Primary outcome [2] 0 0
Percent Change of E1, E2, and E1S Levels at 9, 10.5, and 12 Months From Baseline, by Treatment Group
Timepoint [2] 0 0
9, 10.5, and 12 months from baseline
Secondary outcome [1] 0 0
Toxicity Grade Changes for Arthralgia, Hot Flushes, and Insomnia
Timepoint [1] 0 0
6 and 12 months
Secondary outcome [2] 0 0
Quality of Life (QoL) Score Changes
Timepoint [2] 0 0
6 and 12 months: Change is calculated from 12 months minus 6 months, therefore positive values indicate an improved condition and negative values indicate a declined condition
Secondary outcome [3] 0 0
Change in Grip-strength Score in the Dominant Hand
Timepoint [3] 0 0
Changes in grip strength score is calculated at 12 months minus 9 months
