Summary
Brief summary
This clinical trial is for post and perimenopausal women who after having surgery for their breast cancer are found to have tumours which are stimulated by oestrogens (‘oestrogen receptor positive’) and who have cancer present in the glands of the arm pits (‘positive axillary lymph nodes’). For this group of women it is not known whether the addition of chemotherapy to hormonal treatment is beneficial in reducing disease recurrence and improving survival.

Patients on this trial will all receive a hormonal therapy for their breast cancer. Some patients will also receive chemotherapy either at the same time, or before their hormonal treatment. This will be determined by a process called randomisation which is similar to the toss of a coin. This trial assesses the optimal way of combining these treatments for this type of breast cancer.
