Observational Study of Bone Complications in People With Post-menopausal Breast Cancer Who Have Stopped Treatment With Denosumab and Aromatase Inhibitors

Brief Summary
The purpose of this study to gather information about changes in the bones after stopping treatment with aromatase inhibitor/AI and denosumab. The study team will collect information from 5 standard clinic visits over the course of 24 months. The information will include information about participant health assessments, blood test results, and imaging results. After 24 months, participation in this study will be complete.

Outcome Measures
Primary Outcomes (2)
Change in serum carboxy-terminal collagen crosslinks (CTX)
Evaluate changes in bone turnover markers at 12 months after the last dose of denosumab - serum carboxy-terminal collagen crosslinks (CTX)
12 months
Change in bone specific alkaline phosphatase (ALK)
Evaluate changes in bone turnover markers at 12 months after the last dose of denosumab - bone specific alkaline phosphatase (ALK)
12 months
Study Arms (1)
Post- menopausal breast cancer patients
Participants are post- menopausal with a breast cancer diagnosis who received at least 2 doses of denosumab, and then discontinued therapy, and discontinued Aromatase Inhibitors/AI prior to or within 6 months of stopping denosumab
Interventions
Participants will be assessed at Timepoint 0 (last dose of denosumab injection) and then at 9,12,18 and 24 months following discontinuation of denosumab. The evaluation will include history and pain assessment for development of new fractures, weight and height measurement with BMI (body mass index) calculation, and blood work for bone turnover markers (including serum carboxy-terminal collagen crosslinks (CTX) in serum and bone specific alkaline phosphatase). Bone turn-over markers should be drawn in the morning, after at least 8 hours of fasting (water, black coffee and plain tea allowed).
Dual-energy X-ray absorptiometry (DEXA) scans will be performed at the 12 months timepoint , and then at the 24 month timepoint.
TBS is an innovative gray-level texture measurement that utilizes lumbar spine DEXA images to discriminate changes in bone microarchitecture. Specifically, TBS measures bone quality through tridimensional bone areas with different trabecular and microstructural characteristics. The combination of TBS microstructure evaluation with bone density measured by DEXA has been shown to be superior to either measurement alone in the assessment of fracture risk.
Eligibility Criteria
Patients will be recruited through the Breast Medicine and Survivorship Services. Members of the research team will verify eligibility against the patient's medical record. Once eligibility is confirmed, and if the treating investigator has no objection to enrolling the patient in the research study, the patient will be approached for consent. Consent to the protocol will be conducted by a trained consenting professional. Consent will take place either in the clinic, or by following the most updated standard working procedures for consent via telemedicine.
You may qualify if:
- Women with confirmed diagnosis of breast cancer
- Participant must be post-menopausal, defined as last menstrual cycle at least 12 months prior to enrollment
- Received at least 2 doses of denosumab and then discontinued therapy
- Discontinued AI prior to or within 6 months of last denosumab injection
- Patients must be 18 years of age or olde
You may not qualify if:
- Patients with history of osteoporosis prior to starting denosumab, based on previous dual-energy X-ray absorptiometry (DEXA) scan;
- Patients with history of insufficiency fracture.
- Patients who continue treatment with a different bone modifying agent (i.e oral or intravenous bisphosphonates) after discontinuation of denosumab
- Patients on chronic low-dose glucosteroids.
