Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm A: Ovarian ablation and Tamoxifen (20mg orally daily) maintenance to 5 years
Arm B: Ovarian ablation + 4 cycles of Doxorubicin (60mg/m^2 iv) or epirubicin (90mg/m^2 iv) and cyclophosphamide (600mg/m^2 iv), followed by Tamoxifen (20mg orally daily) maintenance to 5 years.

Ovarian ablation can use any of the following methods:
* bilateral surgical oophorectomy via laparatomy or laparascopy OR
* bilateral ovarian irradiation OR
* GnRH (gonadotropin releasing hormone) analogue 3.6mg every 28 days continued for 2 years or until the patient is 55 years old, whichever is longer. Note: ovarian ablation initiated with GnRH analogue may be continued by oophorectomy or radiation therapy.
Chemotherapy (21 day cycles) should start immediately after the ovarian ablation procedure or at day 1 of GnRH(gonadotropin releasing hormone) analogue administration; within 6 weeks of primary surgery.

Summary
Brief summary
This trial involves premenopausal women who after surgery for their breast cancer are found to have tumours which are hormone receptor positive (stimulated by hormones) and who also have positive axillary lymph nodes (‘glands under the arm pit’ containing cancer). For these women it is not known whether hormonal treatment alone is sufficient, or whether the addition of chemotherapy may be beneficial in reducing the incidence of disease recurrence and improving survival.

Women who take part in this trial will all have their ovarian function suppressed and receive Tamoxifen. In addition, patients may or may not receive chemotherapy.
