Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Active comparator: T+OFS - 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.

Experimental: E+OFS - 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.

* Histologically confirmed breast cancer
* Completely resected disease

* No clinically detectable residual loco-regional axillary disease
* Prior surgery for primary breast cancer of 1 of the following types:

* Total mastectomy with or without adjuvant radiotherapy
* Breast-conserving procedure (e.g., lumpectomy, quadrantectomy, or partial mastectomy with margins negative* for invasive disease and ductal carcinoma in situ) with planned radiotherapy NOTE: *If all other margins are clear a positive posterior (deep) margin is permitted, provided the excision was performed down to the pectoral fascia and all tumor has been removed OR a positive anterior (superficial; abutting skin) margin is allowed provided all tumor was removed
* Tumor confined to the breast and axillary nodes

* Tumor detected in internal mammary chain nodes by sentinel node procedure and is not enlarged is allowed

* Bilateral synchronous invasive breast cancer allowed if disease meets all other eligibility criteria
* No prior ipsilateral or contralateral invasive breast cancer
* Hormone receptor status:

* Estrogen and/or progesterone receptor positive

* At least 10% of the tumor cells positive by immunohistochemistry
* If > 1 breast tumor, each tumor must be hormone receptor positive
