5 I. Bone Metastasis in Breast Cancer Bone Metastasis in Breast Cancer Bone is one of the earliest and most common sites of breast cancer metastasis. [Singletary, S. E(2003)] Between 30-85% of patients with metastatic breast cancer will develop bone metastases during the course of the disease. [Vassiliou, V (2013)] Median survival for bone only metastasis was 24-48months. [Solomayer, E.(2000)] As high as 72months in one study [Briasoulis, E(2004)] Median survival for Visceral metastasis was 12months [Solomayer, E.(2000)] 5-year Survival rate was 39% [Dürr, H. R(2002)] The Nursing needs to focus on Quality of Life

46 Summary Bone is the most common site of breast cancer. The survival of bone metastasis in breast cancer is relatively long. The complications of bone metastasis are Pain, Pathologic fracture, Radiation therapy, Surgical intervention, Spinal cord compression and Hypercalcemia. Treatments are Endocrine Tx, CTx, RTx, OP and the Bone modifying agents. Adverse events of the bone modifying agents are acute phase reaction, renal toxicity, hypocalcemia and osteonecrosis of the jaw.
