NCT00873808

Brief Summary

RATIONALE: Gathering information over time from imaging and laboratory tests of women receiving bisphosphonates for breast cancer may help doctors learn more about long-term bone quality and plan the best treatment. Tetracycline hydrochloride and demeclocycline hydrochloride can mark the new growth of the bone, so it may be seen better under a microscope. PURPOSE: This clinical trial is studying long-term bone quality in women with breast cancer enrolled on clinical trial SWOG-S0307.

Outcome Measures

Primary Outcomes (1)

  • Change in bone quality after long-term high-dose bisphosphonates as measured by histomorphometry, mineralization density, micro-computed tomography, and biomechanics of bone biopsy samples

Secondary Outcomes (2)

  • Comparison of the potency of bisphosphonates as measured by changes in bone quality in each treatment group

  • Correlations among measures of bone formation, structure, mineralization, and strength
