Study Arms:
- Arm I (Type: ACTIVE_COMPARATOR): Patients receive oral anastrozole once daily on days 1-28.
- Arm II (Type: EXPERIMENTAL): Patients receive oral anastrozole as in arm I. Patients also receive fulvestrant intramuscularly on days 1, 14, and 28 during course 1 and then on day 28 of the subsequent courses.

Based on this trial design, predict the completion outcome and termination type (if applicable).
