Intravenous pamidronate versus oral and intravenous clodronate in bone metastatic breast cancer: a randomized open-label non-inferiority Phase III trial

摘要

PurposePatients with metastasized breast cancer often suffer from discomfort caused by metastatic bone disease. Thus, osteoprotection is an important part of therapy in breast cancer metastasized to bone, and bisphosphonates (BPs) are a major therapeutic option. In this study, our objectives were to compare the side effects of oral versus intravenous BP treatment and to assess their clinical effectiveness.
