Adjuvant denosumab for early breast cancer-Evidence and controversy.

The efficacy of adjuvant denosumab in combination with hormonotherapy in breast cancer patients was investigated in two randomized trials, ABCSG-18 and D-Care, but the results were mixed with respect to the impact of this drug on disease-free survival. However, the ABCSG-18 study has achieved its primary goal: prevention of clinical fractures. Therefore, the protective role of Denosumab on bone fragility induced by estrogen deprivation, already demonstrated in post-menopausal women, has been validated in the breast cancer setting.
