Adjuvant bisphosphonates and breast cancer survival

Abstract

Randomized trials have studied bisphosphonates in the adjuvant setting of early breast cancer to investigate their ability to prevent treatment-induced bone loss. Trial results have also suggested their potential to prevent disease recurrence and metastases. These trials are summarized in this review. A recent patient-level meta-analysis by the Early Breast Cancer Trialists' Collaborative Group (EBCTCG) finds convincing evidence that adjuvant antiresorptive treatments provide persistent benefits to breast cancer patients in low-estrogen situations and should be considered an important part of the treatment algorithm.
