Study Arms:
- T+OFS (Type: ACTIVE_COMPARATOR): Ovarian function suppression (OFS) by triptorelin (GnRH analogue) 3.75mg by im injection q28 days for 5 years plus tamoxifen 20mg orally daily for 5 years. Tamoxifen (T) begins after the completion of adjuvant chemotherapy if given, or approximately 6-8 weeks after the initiation of triptorelin. Bilateral oophorectomy or ovarian irradiation was allowed after at least 6 months of triptorelin.
- E+OFS (Type: EXPERIMENTAL): Ovarian function suppression (OFS) by triptorelin (GnRH analogue) 3.75mg by im injection q28 days for 5 years plus exemestane 25mg orally daily for 5 years. Exemestane (E) begins after the completion of adjuvant chemotherapy if given, or approximately 6-8 weeks after the initiation of triptorelin. Bilateral oophorectomy or ovarian irradiation was allowed after at least 6 months of triptorelin.

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