Bone metastases occur in most women with advanced breast cancer and can lead to considerable morbidity and a rapid deterioration in the patient's quality of life. It was the aim of the present study to assess changes in quality of life and bone pain due to intravenous (i.v.) ibandronate, a potent third-generation bisphosphonate. In a phase III randomised, double-blind, placebo-controlled trial in patients with bone metastases due to breast cancer, 466 women were randomised to receive placebo, 2 mg ibandronate or 6 mg ibandronate for up to 96 weeks. Treatment was administered i.v. at 3- or 4-weekly intervals. Clinical endpoints included the incidence of adverse events, quality of life (assessed using the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Scale - Core 30 questionnaire (QLQ-C30)), and bone pain (assessed on a 5-point scale from 0 = none to 4 = intolerable). Ibandronate was generally well tolerated. Compared with baseline measurements, the bone pain score was increased at the last assessment in both the placebo and 2 mg ibandronate groups, but was significantly reduced in the patients receiving 6 mg ibandronate (-0.28 +/- 1.11, P < 0.001). A significant improvement in quality of life was demonstrated for patients treated with ibandronate (P < 0.05) for all global health status. Overall, at the last assessment, the 6 mg ibandronate group showed significantly better functioning compared with placebo (P = 0.004), and had significantly better scores on the domains of physical, emotional, and social functioning, and in global health status (P < 0.05). Significant improvements in the symptoms of fatigue and pain were also observed in the 6 mg ibandronate group. I.v. ibandronate treatment leads to significant improvements in quality of life, and is an effective and well-tolerated palliative treatment in patients with bone metastases due to breast cancer.
