入选标准
- •Patients must be postmenopausal using any one of the following criteria. Because letrozole is not effective in pre- or perimenopausal patients, and may stimulate ovarian function, definitive confirmation of postmenopausal status is required:
- •Patients of any age who have had a bilateral oophorectomy (including radiation
- •castration AND amenorrheic for > 3 months)
- •Patients 56 years old or older. If the patient has any evidence of ovarian function,
- •biochemical evidence of definite postmenopausal status (defined as estradiol, LH,
- •and FSH in the postmenopausal range) is required.
- •Patients 55 years old or younger must have biochemical evidence of definite
- •postmenopausal status (defined as estradiol, LH, and FSH in the postmenopausal
- •range. Patients who have received prior LHRH analogue within the last year are
- •eligible if they have definite evidence of postmenopausal status as defined above.
- •Patients must be accessible for follow-up.
- •At diagnosis, patients must have had operable, non-inflammatory breast cancer.
- •Patients must be clinically disease-free at randomization.
- •Patients must have had steroid hormone receptor positive tumors (ER and/or PgR), determined by immunohistochemistry, after primary surgery and before commencement of prior endocrine therapy.
- •Following primary surgery, eligible patients must have had evidence of lymph node involvement either in the axillary or internal mammary nodes, but not supraclavicular nodes.
- •There must have been no evidence of recurrent disease or distant metastatic disease at any time prior to randomization.
- •Patients must have had proper local treatment including surgery with or without radiotherapy for primary breast cancer with no known clinical residual loco-regional disease.
- •Patients must have clinically adequate hepatic function.
- •Patients must have completed 4 to 6 years of prior adjuvant endocrine therapy with SERM(s), aromatase inhibitor(s), or a sequential combination of both. When calculating 4-6 years, neoadjuvant endocrine therapy should not be included.
- •Patients must have stopped prior endocrine SERM/AI therapy, and must be randomized within 12 months (1 year) of the last dose of prior endocrine SERM/AI therapy.
- •Patients may have received any type of prior adjuvant therapy, including but not limited to neoadjuvant chemotherapy, neoadjuvant endocrine therapy, adjuvant chemotherapy, trastuzumab, ovarian ablation, GnRH analogues, lapatinib.
- •Patients must have stopped hormone replacement therapy (HRT), bisphosphonates (except for treatment of bone loss), or any investigational agent at randomization. (Note: These agents are also not permitted during trial treatment.)
- •Pathology material from the primary tumor must be available for submission for
- •central review as part of the quality control measures for this protocol.
排除标准
- •Patients who have had bilateral breast cancer.
- •Patients who have had a bone fracture due to osteoporosis at any time during the 4-6 years of prior endocrine SERM/AI therapy.
- •Patients who have had any 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 who have had any other non-malignant systemic diseases (cardiovascular, renal, lung, etc.) that would prevent prolonged follow-up.
- •Patients with psychiatric, addictive, or any disorder which compromises compliance with protocol requirements.
