Primary Outcome Measures:
  • Mammographic percentage density at 18months [ Time Frame: 18months after enrolled ]

Secondary Outcome Measures:
  • estrogen levels, lipidemia, endometrial thickness and ultrasonographic abnormalities [ Time Frame: 3,6,12,18 months ]

Estimated Enrollment: 100
Study Start Date: June 2008
Study Completion Date: August 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Combination
In the combination arm, patients receive ZOLADEX 3.6 mg by subcutaneous injection every 4 weeks along with once-daily oral dose of tamoxifen 20 mg.
Drug: Goserelin
In the combination arm, patients receive ZOLADEX 3.6 mg by subcutaneous injection every 4 weeks along with once-daily oral dose of tamoxifen 20 mg
Other Name: ZOLADEX
Active Comparator: Conctrol
In the monotherapy arm, patients receive once-daily oral dose of tamoxifen 20 mg.
Drug: tamoxifen
In the monotherapy arm, patients receive once-daily oral dose of tamoxifen 20 mg.
Other Name: TAM

Detailed Description:

After the completion of primary treatment(surgery and/or adjuvant chemotherapy, radiotherapy could be given concurrently with study medication), eligible patients will be randomized to receive Zoladex plus tamoxifen or tamoxifen alone. The duration of study medication along with the follow-up will be 18 months, or until disease recurrence,or discontinuation of study therapy (as a result of an adverse event, a patient's request, or an investigator's decision), further treatment will be at investigator's discretion.

During the study period, contralateral mammograms and transvaginal ultrasound will be undertaken at baseline and after 6, 12 and 18 months of study medications. Mammographic density assessment will be undertaken by a single radiologist. Serum measurements including estrogen levels and lipidemia will be obtained at baseline and after 3, 6, 12 and 18 months of study medications.


Ages Eligible for Study:   18 Years to 50 Years   (Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • provision of informed consent
  • histologically proven HR+ operable invasive breast cancer
  • completion of surgery and chemotherapy(if given).
  • women defined as pre- or perimenopausal according to all of the following: aged 50 years or younger, at least one menstrual period during the last months.

Exclusion Criteria:

  • clinical evidence of metastatic disease
  • pregnancy or breast-feeding
  • bilateral oophorectomy;
  • radiation of the ovaries
  • patients who, for whatever reason(eg, confusion, infirmity,alcoholism),are unlikely to comply with trial requirements
  • patients whose chemotherapy was started more than 8 weeks after completion of primary surgery or whose chemotherapy was completed more than 8 weeks before starting the study treatment. Chemotherapy, if given, should have been given post-operatively, ie, patients who received neoadjuvant chemotherapy are ineligible
  • patients who have not received chemotherapy and whose primary surgery was completed more than 8 weeks before starting the study treatment
  • previous hormonal therapy as adjuvant treatment for breast cancer

  • treatment with a non-approved or experimental drug during 1 month before entry into the study
  • history of hypersensitivity to active or inactive excipients of tamoxifen and Zoladex
  • history of bleeding diathesis (ie. Disseminated intravascular coagulation, clotting factor deficiency), or long term anticoagulant therapy (other than antiplatelet therapy and low dose warfarin )
  • leukopenia and/or thrombocytopenia
  • history of ocular fundus diseases
  • history of thromboembolic diseases
