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] Bone metastases can be classified as osteolytic, osteoblastic ...
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]
Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. About 30% of bone sarcomas are chondrosarcomas. [2] It is resistant to chemotherapy and radiotherapy. Unlike other primary ...

If there are no symptoms, but a paraprotein typical of myeloma and diagnostic bone marrow is present without end-organ damage, treatment is usually deferred or restricted to clinical trials. [105] Treatment for multiple myeloma is focused on decreasing the clonal plasma cell population and consequently decrease the symptoms of disease.
The goals of therapy are to control symptoms, improve quality of life, improve overall survival, and decrease progression to AML. The IPSS scoring system can help guide therapy for patients with MDS. [ 43 ] [ 44 ] In those with low risk MDS (designated by an IPSS score less than 3.5), no disease specific treatment has been found to be helpful ...
The bone showed typical characteristics of cancer, including areas of cortical destruction, neoplastic bone formations, and disordered organization inconsistent with a simple fracture or infection. The structural and histological similarities with a high-grade human osteosarcoma case strengthened the diagnosis.
Myeloproliferative neoplasms (MPNs) are a group of rare blood cancers in which excess red blood cells, white blood cells or platelets are produced in the bone marrow. Myelo refers to the bone marrow, proliferative describes the rapid growth of blood cells and neoplasm describes that growth as abnormal and uncontrolled.
