Brief Summary:
The purpose of this study is to compare 5-year disease free survival rate (DFS rate) between the hormone receptor positive breast cancer patients who were added Goserelin to Tamoxifen for ovarian function suppression after neo-/adjuvant cytotoxic chemotherapy and the hormone receptor positive breast cancer patients who were treated with Tamoxifen.

Condition or disease Intervention/treatment Phase
Breast Cancer Drug: goserelin Drug: tamoxifen Phase 3

Detailed Description:
  • To compare overall Survival(OS) between the patients added Goserelin(ZOLADEXTM) to Tamoxifen and the patients treated with Tamoxifen alone in premenopausal status
  • To compare 5-year disease free survival rate (DFS rate) between the patients who took tamoxifen only in postmenopause and the patients added Goserelin(ZOLADEXTM) to Tamoxifen for inducing ovarian function suppression in premenopause
  • To determine the tolerability and safety of Tamoxifen with or without concomitant Zoladex

Arm Intervention/treatment
Experimental: TAM+OFS(E) group

Patients should be premenopausal women ,prior to the start of chemotherapy, less than or equal to 45 years of age with oestrogen receptor positive ± progesterone receptor positive who have undergone a primary mass excision, received an neo-/adjuvant chemotherapy ± radiotherapy for their stage I, II or III breast cancer. This arm is ovarian suppression group which have a various starting time of ovarian function suppression after neo-/adjuvant chemotherapy.

Ovarian function suppression will be done by administration of LHRH agonist (ZOLADEXTM) for 2 years. After that, the patients will complete taking tamoxifen 20mg/day for 5 years.

 Drug: goserelin

  1. Zoladex™ administration:

    Zoladex™ depot is available as a sterile disposable syringe. The depot is administered subcutaneously under the abdominal skin under sterile conditions. If necessary the injection site may be pre-treated with a local anaesthetic.

  2. Sequence of administration Zoladex depot:

    The substance is administered for 24 months (2 years) at 28-day intervals (a period of 34 days between 2 administrations must not be exceeded).

  3. Dosage:

    Each depot contains 3.6mg Zoladex. The substance Zoladex is contained in a while cylindrical rodlet .

  4. Storage instructions for Zoladex™ Zoladex™ is kept a room temperature.
Other Name: Zoladex®

Drug: tamoxifen

  1. Dose and period of Tamoxifen therapy:

    Tamoxifen is administered in tablet form. Each day 2 X 10 mg or 1 X 20 mg Tamoxifen are taken in the form of the respective tablet.

  2. Storage instructions for Tamoxifen Tamoxifen is stored at room temperature away from light.
Other Name: Nolvadex
Active Comparator: TAM(D) group
Patients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. At 0, 6, 12, 18 and 24 months since the baseline asTsessment(0), the ovarian function status will be evaluated by menstruation status or serum FSH level. If the patients are regarded as the premenopausal women, they will be randomized into the additional ovarian function suppression group or tamoxifen only group. The latter will complete taking tamoxifen 20mg/day for 5 years.
 Drug: tamoxifen

  1. Dose and period of Tamoxifen therapy:

    Tamoxifen is administered in tablet form. Each day 2 X 10 mg or 1 X 20 mg Tamoxifen are taken in the form of the respective tablet.

  2. Storage instructions for Tamoxifen Tamoxifen is stored at room temperature away from light.
Other Name: Nolvadex
No Intervention: Permanent postmenopausal(A) group
Patients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. Eligible patients except for premenopausal status at the baseline will be followed up until 2 years after the baseline assessment for evaluating the menopausal status. This group still remains to postmenopausal status and will taking tamoxifen 20mg/day for 5 years if they remain in the study.
Active Comparator: TAM(B)
Patients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. At 6, 12, 18 and 24 months since the baseline assessment (0), the ovarian function status will be evaluated by menstruation status or serum FSH level. If the patients are regarded as the premenopausal women, they will be randomized into the additional ovarian function suppression group or tamoxifen only group. This group, patients are premenopausal women, they will be randomized into tamoxifen only group, complete taking tamoxifen 20mg/day for 5 years.
 Drug: tamoxifen

  1. Dose and period of Tamoxifen therapy:

    Tamoxifen is administered in tablet form. Each day 2 X 10 mg or 1 X 20 mg Tamoxifen are taken in the form of the respective tablet.

  2. Storage instructions for Tamoxifen Tamoxifen is stored at room temperature away from light.
Other Name: Nolvadex
Experimental: TAM+OFS (C)
Patients, less than or equal to 45 years of age with hormone receptor positive breast cancer will be enrolled. Included All the patients have already treated by surgery, neo- or adjuvant chemotherapy ±and/or radiotherapy before enrolment. At 6, 12, 18 and 24 months since the baseline assessment (0), the ovarian function status will be evaluated by menstruation status or serum FSH level. If the patients are regarded as the premenopausal women, they will be randomized. This group, patients are premenopausal women, they will be randomized into the additional ovarian function suppression group. Ovarian function suppression will be done by administration of LHRH agonist (ZOLADEXTM) for 2 years. Then, Patients will complete taking tamoxifen 20mg/day for 5 years.
