[Intravenous pamidronate delivery to a case with multiple bone metastasis of breast cancer]

MRI and bone scintigraphy of a 64-year-old woman admitted with severe lumbago showed multiple metastatic bone cancer mainly on vertebrae, and breast cancer was found by mammography. After enucleation was performed, treatment with tegafur, tamoxifen and oral bisphosphonate/etidronate was started. Because symptoms associated with bone metastasis worsened, we began to administer 30 mg of pamidronate intravenously every 4 weeks. Since that time the extent of metastasis has been inhibited, resulting in ameliorated lumbodynia and improved quality of life.
