入选标准
- •Premenopausal women [estradiol (E2) in the premenopausal range (according to
- •institution parameters)] who meet the following criteria:
- •Patients who did not receive chemotherapy should be randomized within 12 weeks after definitive surgery; such patients should have estradiol (E2) in the premenopausal range following surgery.
- •Patients who received prior adjuvant and/or neoadjuvant chemotherapy should be
- •randomized after completing chemotherapy and within 6 months of the final dose of
- •chemotherapy as soon as premenopausal status is confirmed; such patients should have estradiol (E2) in the premenopausal range between 2 weeks and 6 months after completing chemotherapy.
- •Patients with temporary chemotherapy-induced amenorrhea who regain premenopausal status within six months of the final dose of chemotherapy are eligible. [Attention: under tamoxifen or aromatase inhibitors, even without evidence of menses, some women may have ovarian function recovery following chemotherapy and resume estradiol secretion.]
- •Premenopausal levels of serum estradiol may persist after chemotherapy-induced amenorrhea despite prolonged amenorrhea.
- •Histologically proven, resected breast cancer. Pathology material should be available for submission for central review as part of the quality control measures for this protocol.
- •Patients must have hormone receptor positive tumors. Hormone receptors must be
- •determined using immunohistochemistry. ER and/or PgR must be greater than or equal to 10% of the tumor cells positive by immunohistochemical evaluation. Biochemical determination alone is not acceptable. Detailed guidelines for assessments of ER and PgR are given in the Appendix III.
- •The tumor must be confined to the breast and axillary nodes without detected metastases elsewhere, with the exception of tumor detected in internal mammary chain nodes by sentinel node procedure. Patients who received neoadjuvant therapy must have had operable disease prior to neoadjuvant treatment to be eligible. Patients who had a pathological evaluation with tru cut or core biopsy of invasive breast cancer prior to neoadjuvant therapy and were found to have
- •no invasive tumor in the pathological specimen from definitive surgery are eligible. For these patients, pre-neoadjuvant tumor characteristics will be used for defining eligibility. In case of persistent disease, pathology findings from the definitive surgery should be used.
- •Patients must have had proper surgery for primary breast cancer with no known clinical residual loco-regional disease.
- •A total mastectomy. Radiotherapy is optional after mastectomy.
- •A breast-conserving procedure (lumpectomy, quadrantectomy or partial mastectomy with margins clear of invasive cancer and DCIS). The local pathologist must document negative margins of resection in the pathology report. Radiation therapy to the conserved breast is required.
- •Either axillary lymph node dissection (pathological examination of at least 6 nodes
- •recommended) or a negative axillary sentinel node biopsy [pN0(sn)] is required. Patients with positive axillary nodes require axillary dissection, except for patients with microscopically positive (pN1mi: micrometastasis > 0.2mm, none > 2.0mm) axillary sentinel nodes who are randomized in a clinical trial evaluating microscopically positive lymph nodes.
- •For IBCSG centers, patients must have completed baseline Quality of Life (QL) Forms
- •prior to randomization. The only exceptions are cognitive or physical impairment tha
排除标准
- •Patients who are postmenopausal (i.e., do not have an estradiol (E2) level in the premenopausal range) after surgery or after chemotherapy, whichever is later.
- •Patients with distant metastatic disease.
- •Patients with locally advanced inoperable breast cancer including inflammatory breast
- •cancer or supraclavicular node involvement or with enlarged internal mammary nodes (unless pathologically negative) are not eligible. Patients with involved internal mammary nodes detected by sentinel node biopsy that are not enlarged are eligible.
- •Patients with bilateral invasive breast cancer.
- •Patients with positive final margins (referring to only DCIS and invasive cancer, not
- •Patients with clinically detectable residual axillary disease.
- •Patients with a history of prior ipsilateral or contralateral invasive breast cancer.
- •Patients with previous or concomitant malignancy EXCEPT adequately treated: basal or squamous cell carcinoma of the skin in situ carcinoma of the cervix or bladder,
- •contra- or ipsilateral in situ breast carcinoma.
- •Patients with other non-malignant systemic diseases (cardiovascular, renal, hepatic, lung, etc.) that would prevent prolonged follow-up. Patients with previous thrombosis (e.g., DVT) and/or embolism can be included only if medically suitable.
- •Patients who have had a bilateral oophorectomy or ovarian irradiation or are planning oophorectomy within 5 years.
- •Patients with a history of noncompliance to medical regimens and patients who are
- •considered potentially unreliable.
- •Patients who are pregnant or lactating at the time of randomization or who desire a
- •pregnancy within 5 years. Patients planning to use additional hormonal therapy apart from the randomized treatment (see Section 5.3.1) during the next five years including all types of hormonal contraception.
- •Patients who received endocrine therapy (including neoadjuvant and adjuvant) for more than 6 months after their breast cancer diagnosis.
- •Patients who were taking tamoxifen or other SERM (e.g. Raloxifene) or hormone
- •replacement therapy (HRT) within one year prior to their breast cancer diagnosis. Prior oral contraceptives are allowed.
- •Patients who have received GnRH analogues as part of their breast cancer treatment prior to randomization.
- •Patients with psychiatric, addictive, or any disorder, which compromises ability to give
- •informed consent for participation in this study.
