Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma , chondrosarcoma , and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [ 1 ]
Zoledronic acid is used to prevent bone fractures in patients with cancers such as multiple myeloma and prostate cancer, as well as for treating osteoporosis. [10] It can also be used to treat hypercalcaemia of malignancy and can be helpful for treating pain from bone metastases.
223 Ra was the first α-emitter approved by the FDA in the United States for treatment of bone metastases from prostate cancer, and is a recommended treatment in the UK by NICE. [3] [15] In a phase III trial comparing 223 Ra to a placebo, survival was significantly improved. [16]
Denosumab, sold under the brand names Prolia among others, is a human monoclonal antibody used for the treatment of osteoporosis, treatment-induced bone loss, metastases to bone, and giant cell tumor of bone. [11] [12] The most common side effects are joint and muscle pain in the arms or legs. [13]
Metastasis is a key element in cancer staging systems such as the TNM staging system, where it represents the "M". In overall stage grouping, metastasis places a cancer in Stage IV. The possibilities of curative treatment are greatly reduced, or often entirely removed when a cancer has metastasized.
Radiotherapy is essential in the treatment of brain metastases from breast cancer, as it halts tumor progression quickly and can induce a response in the majority of patients. [26] Bone metastases. The bones are a very common site of metastatic disease from breast cancer, and bone metastases can cause severe pain, hypercalcemia and pathologic ...
A major use of systemic radioisotope therapy is in the treatment of bone metastasis from cancer. The radioisotopes travel selectively to areas of damaged bone, and spare normal undamaged bone. Isotopes commonly used in the treatment of bone metastasis are radium-223, [112] strontium-89 and samarium (153 Sm) lexidronam. [113]
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
