Summary
This trial is comparing two hormone therapies to see which is more effective in treating premenopausal women with hormone responsive breast cancer.
Who is the study for?
This trial is for premenopausal women with hormone-responsive breast cancer that's been surgically removed and isn't widespread. Participants must not be pregnant, should use nonhormonal birth control, and have no history of other cancers or serious diseases in the last 5 years. They can't be on hormonal treatments or have had prior chemotherapy for breast cancer.
What is being tested?
The study compares two hormone-blocking treatments: triptorelin with exemestane versus triptorelin with tamoxifen. It aims to find out which combination is more effective at preventing the growth of breast cancer cells by blocking estrogen.
What are the potential side effects?
Triptorelin may cause menopause-like symptoms, exemestane might lead to joint pain or hot flashes, and tamoxifen could increase risk of blood clots and uterine changes. Side effects vary from person to person.

Experimental Treatment
Active Control
Group I: E+OFSExperimental Treatment2 Interventions
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.
Group II: T+OFSActive Control2 Interventions
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.
