Study of Bone Mineral Density in Women With Breast Cancer Treated With Triptorelin and Tamoxifen or Exemestane on Protocol IBCSG 25-02 (TEXT-Bone)
Breast Cancer, Osteoporosis
About this trial
This is an interventional treatment trial for Breast Cancer focused on measuring osteoporosis, estrogen receptor-positive breast cancer, progesterone receptor-positive breast cancer, stage IA breast cancer, stage IB breast cancer, stage II breast cancer, stage IIIA breast cancer
Eligibility Criteria
DISEASE CHARACTERISTICS:
- Patient must be eligible and enrolled in the TEXT-2 trial prior to enrolling in TEXT-Bone
- Serial bone marrow density (BMD) measurements must be taken within the same institution
- Hormone receptor positive
PATIENT CHARACTERISTICS:
- See Disease Characteristics
- Premenopausal
- No bone fracture in the past 6 months that, in the investigator's judgement, could be related to bone fragility
- No clinical or biochemical malabsorption syndrome, known vitamin D deficiency, active hyper- or hypoparathyroidism, or Paget's disease
- No uncontrolled thyroid disease, Cushing disease, or other pituitary diseases
- No other bone disease (including osteomalacia or osteogenesis imperfecta)
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- At least 6 months since prior and no concurrent bisphosphonate therapy (or other bone therapies such as PTH or strontium)
- At least 6 months since prior glucocorticoid (> 5 mg prednisone or equivalent) for > 1 month
- At least 12 months since prior anticonvulsants
