Bone metastases: Part I--Pathophysiology.
Many cancers (especially breast, prostate, and lung cancers) metastasize to the bone. The most frequent site of bone involvement is the axial skeleton (i.e., cranium, ribs, spine, and pelvis). The sequelae of bone metastases include pain, hypercalcemia, pathologic fractures, and spinal cord compression. As patients survive for longer periods, effective management of bone metastases becomes critical to maintaining or improving quality of life. Controlling pain, preventing fractures and oncologic emergencies, and promoting mobility and function are the outcomes of successful management. Use of a clinical algorithm can assist the nurse in identifying bone metastases and managing the clinical sequelae. Knowledge of the pathophysiology and the ability to assess bone metastases will contribute to the nurse's ability to manage the clinical problems and to improve the quality of life of patients with cancer.
