Current Trend in Metastatic Bone Tumor Treatment

Special Issue M etastatic bone tumor is a clinical challenge to most orthopaedic surgeons, and physicians. The bone lesions present pain, can progress to pathologic fractures, and cause neurologic deficits. The adequate treatment for the lesions can mean the difference between good and poor quality of life during their remaining time. The goals of the treatment are relief of pain, preservation of function, and maintenance of independence. In orthopaedic field, the goals include prophylactic fixation of metastatic deposits when there is a risk of fracture, stabilization or reconstruction after pathological fracture, and decompression the spinal cord and nerve roots and/or stabilization the spine. To achieve the goals, we should understand the evaluation methods, a pathogenesis of metastasis and the characters of the specific metastatic site. Finally we should have a knowledge about the treatment strategy and understand what the indications of operative treatment are and which conservative managements is correct for the metastatic bone lesions. It is important to consider the type of primary cancer, location of metastasis, extent of disease, expected patient life span, comorbidities, and level of pain when making treatment recommendations. New discoveries and modifications of existing treatments such as percutaneous stabilization of spinal compression fractures and the use of bisphosphonates may decrease the need for invasive surgical management of metastatic bone lesions in the future. Metastatic bone disease should be approached systematically by multidisciplinary team that has various treatment options, and then quality of life of the patients can be improved during their remaining life span. All the doctors participating in the treatment should try to do their best to get an optimal goal, even though the patients should be informed clearly that the treatments may not be curative.
