Primary Outcome Measures:
  • Resumption of menstruation [ Time Frame: 1 year ]
    the Resumption that patients recover the natural menstrual or serum E2, FSH, LH return to the premenopausal range within 1 year after stopping Zoladex


Secondary Outcome Measures:
  • RFS [ Time Frame: 5years ]
    Relapse free survival (RFS): RFS related events ware defined as local-regional recurrence, distant metastasis or death, whichever occurred first.during follow up

  • OS [ Time Frame: 5 years ]
    Overall survival

  • Other adverse events [ Time Frame: 5years ]
    Other adverse events (Gynecological events, blood lipids, thrombosis, cardiovascular diseases, and etc.)

Detailed Description:
Data showed that ovarian suppression therapy may protect the ovarian function in premenopausal patients received chemotherapy for breast cancer. However this is still a controversial issue. Sequential use of GnRHa (Zoladex) as ovarian suppression treatment after chemotherapy has been established as an effective endocrine therapy for ER positive premenopausal breast cancer. The present study is a randomized open-label phase III study that aims to observe the efficacy and safety of the adjuvant chemotherapy with simultaneous combination of Zoladex up to 2-3years and chemotherapy compared with the sequential schedule in ≤ 45 year old premenopausal hormone receptor-positive breast cancer patients.
