This network meta-analysis evaluated the efficacy and safety of bisphosphonates in reducing skeletal-related events in 14,934 patients with bone metastases from breast cancer. Clodronate was found to be the most effective in reducing pathological fractures, with a significant difference compared to pamidronate (OR = -1.41) and zoledronate (OR = -1.44).
Key findings
- Clodronate was most effective in reducing pathological fractures compared to other bisphosphonates.
- Significant differences in fracture reduction were noted between clodronate and pamidronate, and clodronate and zoledronate.
- Zoledronate was more effective than clodronate and pamidronate for hypercalcemia reduction, though not statistically significant.
- Ibandronate had fewer adverse reactions than clodronate and zoledronate, with a significant difference from zoledronate.
Why it matters
Understanding the comparative efficacy and safety of bisphosphonates can guide clinicians in selecting appropriate treatments for patients with bone metastases from breast cancer, potentially improving patient outcomes.
