Considering the results of clinical trials for metastatic tumors, local therapy for one or a few pulmonary or BM in DTC should be considered, if expected to improve prognosis and QOL. Surgical intervention is recommended for spinal metastases presenting with spinal compression symptoms or for long BM in extremities at risk of pathological or impending fractures. BMAs are also recommended to reduce the risk of skeletal-related events. Surgery, stereotactic radiotherapy, and whole-brain radiotherapy are suggested for brain metastases to improve the prognosis and QOL.<\/jats:p>\n                  <\/jats:sec>\n
