First posted: 2009-06-03
Enrollment: 1234
Sex: FEMALE
Minimum age (years): 18
Maximum age (years): 45
Standard ages: ADULT
Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: FACTORIAL
Primary purpose: TREATMENT

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.

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

Eligibility criteria: Inclusion Criteria:

1. Patients must have undergone excision of the primary breast mass, proven histologically to be invasive breast adenocarcinoma.
2. Patients must be within 3 months after the last cycle of chemotherapy.
3. Patients must have the history of normal menstruation prior to the start of chemotherapy.
4. Stage I, II or III
5. Woman, less than or equal to 45 years of age
6. Hormone receptor status : ER+ve and/or PgR+ve
7. WHO performance status 0, 1 or 2.
8. Patients who were treated with cytotoxic chemotherapy in pre- or post- surgery.
9. Adequate haematological function defined by haemoglobin 10g/dL, neutrophil count 1.5x109/L and platelets 100x109/L.
10. Adequate hepatic function defined by AST and ALT 2.5xupper limit of normal. Alkaline phosphatase 5xupper limit of normal, unless bone metastases in the absence of liver disease. Renal function adequate defined by creatinine\<175mmol/L.

Exclusion Criteria:

1. Patients whose primary breast cancer was classified as:

   * ER(-),ER unknown
2. Patients with the history of hysterectomy or oophorectomy
3. Sarcomas or squamous cell carcinomas of the breast are not eligible.
4. Patients with malignancies (other than breast cancer) within the last 5 years, except for adequately treated in situ carcinoma of the cervix or basal cell / squamous cell carcinoma of the skin.
5. Investigational drugs given within the previous 4 weeks.
6. Patients known to be on any unlicensed non-cancer investigational agent.
7. Patients with thrombocytopaenia (platelets \<100 x 109/l or on anti- coagulant therapy (contra-indicated due to risk of bleeding with i.m. injection of Zoladex).
8. Patients treated with CMF(cyclophosphamide/methotrexate/5-fluorouracil) as prior chemotherapy
9. Patients who are pregnant or lactating are ineligible.
