Brief Summary
This study will recruit 168 patients in approximately 20 study centres in China.
The primary objective of this study is to examine whether ZOLADEX 10.8 mg depot is non-inferior to ZOLADEX 3.6 mg depot in terms of the suppression rate of serum estradiol (E2) to the menopausal level (≤30 pg/mL) from Week 4 through Week 24.

Menses within 1 year before enrolment and within 3 weeks before enrolment, E2 \>30 pg/mL and FSH ≤40 mIU/mL.
Patients who received neo/adjuvant chemotherapy before randomisation should not having chemical menopause (Patients should meet: E2\>30pg/mL and FSH ≤40mIU/mL) within 12 weeks after completion of the postoperative chemotherapy.
Histologically confirmed ER+/HER2- primary invasive operable breast cancer (ER+ defined as at least 1% of the cells examined by immunohistochemistry testing have estrogen receptors).
Neoadjuvant chemotherapy and adjuvant chemotherapy prior to study enrolment are acceptable. (Please refer to Guidelines such as NCCN Clinical practice guidelines in oncology-breast cancer and CSCO-BC breast cancer guidelines for standard protocols and dosages. Please make accurate records.).
Have had proper surgery for primary breast cancer with no known clinical residual loco regional disease.
World Health Organization (WHO) performance status of 0, 1, or 2.
Female patients of child bearing potential and their partners, who are sexually active, must agree to the use of two highly effective forms of contraception in combination throughout the period of taking study treatment and for at least 3 month after last dose of Zoladex or Tamoxifen which happens later, or they must totally/truly abstain from any form of sexual intercourse.
You may not qualify if:
Any evidence of metastatic disease.
Have received other previous neo/adjuvant endocrine therapy for breast cancer.
Other malignancy within the last 3 years except adequately treated basal cell/squamous cell carcinoma of the skin or cancer of the cervix.
Have any unstable complication or uncontrolled infection during screening.
Patients considered at poor medical risk due to a serious, uncontrolled medical disorder, non malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, extensive bilateral lung disease on High Resolution Computed Tomography scan or any psychiatric disorder that prohibits obtaining informed consent.
