A multifaceted role of bisphosphonates from palliative care to anti-cancer therapy in solid tumors.

This review article focuses on the antitumor activity of bisphosphonates, safety profile, and the role of bisphosphonates as preventive, neoadjuvant, and adjuvant chemotherapy. A significant improvement in overall survival and cancer-specific survival and recurrence-free survival with the usage of bisphosphonates is noted in breast cancer patients, particularly in post-menopausal women. Though great progress has been achieved in over 20 years, further research is needed to identify the subgroup of patients that are most likely to benefit from adjuvant bisphosphonate therapy and to determine regimens with greater efficacy and better safety profile.
