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 ...
Other pathological factors such as the degree of p-glycoprotein, whether the tumor is cxcr4-positive, [30] or Her2-positive are also important, as these are associated with distant metastases to the lung. The prognosis for patients with metastatic osteosarcoma improves with longer times to metastases (more than 12 months to 4 months), a smaller ...
Geriatric oncology is a branch of medicine that is concerned with the diagnosis and treatment of cancer in the elderly, usually defined as aged 65 and older. This fairly young but increasingly important subspecialty incorporates the special needs of the elderly into the treatment of cancer.
People usually have a good survival rate at the low-grade volume of cancer. [3] For the most aggressive grade, only 10% of patients will survive one year. Tumors may recur in the future. Follow up scans are extremely important for chondrosarcoma to make sure there has been no recurrence or metastasis, which usually occurs in the lungs. [14]
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]
A bone sarcoma is a primary malignant bone tumour, a type of sarcoma that starts in the bones. [1] This is in contrast to most bone cancers that are secondary having developed as a metastasis from another cancer. Bone sarcomas are rare, and mostly affect the legs. The other type of sarcoma is a soft-tissue sarcoma.
The Bone Cancer Research Trust provides information (online and printed) on primary bone cancers for patients, their families, the general public, media and health care professionals. Currently there is detailed information on osteosarcoma, Ewing sarcoma and chondrosarcoma and a glossary/ medical dictionary.
The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer. The 5-year relative survival rate drops to 22% for women with stage IV breast cancer. [3] In cancer types with high survival ...
