A sarcoma is a malignant tumor, a type of cancer that arises from cells of mesenchymal origin. Connective tissue is a broad term that includes bone, cartilage, fat, vascular, or other structural tissues, and sarcomas can arise in any of these types of tissues. As a result, there are many subtypes of sarcoma, which are classified based on the specific tissue and type of cell from which the tumor originates. Sarcomas are primary connective tissue tumors, meaning that they arise in connective tissues. This is in contrast to secondary connective tissue tumors, which occur when a cancer from elsewhere in the body spreads to the connective tissue. Sarcomas are one of five different types of cancer, classified by the cell type from which they originate. The word sarcoma is derived from the Greek σάρκωμα sarkōma 'fleshy excrescence or substance', itself from σάρξsarx meaning 'flesh'.
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. There may be a lump, pain, or neurological signs from pressure. A bone tumor might present with a pathologic fracture. Other symptoms may include fatigue, fever, weight loss, anemia and nausea. Sometimes there are no symptoms and the tumour is found when investigating another problem.
An osteosarcoma (OS) or osteogenic sarcoma (OGS) is a cancerous tumor in a bone. Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin and that exhibits osteoblastic differentiation and produces malignant osteoid.
Cancer Research UK (CRUK) is the world's largest independent cancer research organisation. It is registered as a charity in the United Kingdom and Isle of Man, and was formed on 4 February 2002 by the merger of The Cancer Research Campaign and the Imperial Cancer Research Fund. Cancer Research UK conducts research using both its own staff and grant-funded researchers. It also provides information about cancer and runs campaigns aimed at raising awareness and influencing public policy.
Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. 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. It is resistant to chemotherapy and radiotherapy. Unlike other primary bone sarcomas that mainly affect children and adolescents, a chondrosarcoma can present at any age. It more often affects the axial skeleton than the appendicular skeleton.
The Brain Tumour Charity is a UK-based, Charity Commission registered, charity dedicated to funding research, raising awareness of brain tumours, reducing diagnosis times and providing support and information for people with brain tumours, their families and friends.
Teenage Cancer Trust is a cancer care and support charity in the UK that exists to improve the cancer experience of young people aged 13–24. Founded in 1990, the charity's key service is providing specialist teenage units in NHS hospitals. It also trains and funds staff who are teenage cancer specialists. The units are dedicated areas for teenage and young adult patients, who are involved in their concept and creation. Medical facilities on the units are equipped with computers, TVs and game consoles.
Ewing sarcoma is a type of pediatric cancer that forms in bone or soft tissue. Symptoms may include swelling and pain at the site of the tumor, fever, and a bone fracture. The most common areas where it begins are the legs, pelvis, and chest wall. In about 25% of cases, the cancer has already spread to other parts of the body at the time of diagnosis. Complications may include a pleural effusion or paraplegia.
Orthopedic pathology, also known as bone pathology is a subspecialty of surgical pathology which deals with the diagnosis and feature of many bone diseases, specifically studying the cause and effects of disorders of the musculoskeletal system. It uses gross and microscopic findings along with the findings of in vivo radiological studies, and occasionally, specimen radiographs to diagnose diseases of the bones.
The Codman triangle is the triangular area of new subperiosteal bone that is created when a lesion, often a tumour, raises the periosteum away from the bone. A Codman triangle is not actually a full triangle. Instead, it is often a pseudotriangle on radiographic findings, with ossification on the original bone and one additional side of the triangle, which forms a two sided triangle with one open side. This two sided appearance is generated due to a tumor that is growing at a rate which is faster than the periosteum can grow or expand, so instead of dimpling, the periosteum tears away and provides ossification on the second edge of the triangle. The advancing tumour displaces the periosteum away from the bone medulla. The displaced and now lateral periosteum attempts to regenerate underlying bone. This describes a periosteal reaction.
The Ewing family of tumors (EFTs) is a group of small cell sarcomas including Ewing sarcoma of the bone, extra osseous Ewing tumors, and primitive neuroectodermal tumors. They are rare cancers, usually diagnosed in peoples' twenties. The sarcoma of bone is the most common of the variants. All forms are predisposed to metastasis and have had historically high rates of mortality. The family of tumors shares a common translocation mutation of the EWS gene on chromosome 22 to an ETS-type gene, most commonly the FLI1 gene. EFTs are highly malignant, with 5-year survival for patients with metastatic disease at 20%. The current standard of care includes resection, radiation, and chemotherapy.
Extraskeletal myxoid chondrosarcoma (EMC) is a rare low-grade malignant mesenchymal neoplasm of the soft tissues, that differs from other sarcomas by unique histology and characteristic chromosomal translocations. There is an uncertain differentiation and neuroendocrine differentiation is even possible.
Øyvind Sverre Bruland is a professor of Clinical Oncology and faculty of Medicine at the University of Oslo. Bruland holds a B.Sc., M.D and Ph.D. from the University of Oslo, Norway. His research includes: primary bone and soft tissue cancers (sarcomas) and skeletal metastases from prostate cancer and breast cancer; targeted radionuclide therapy, for instance the clinical development of Alpharadin, based on Radium-223; the tumor biology and prognostic impact of micro-metastases in bone-marrow aspirates on patients with primary bone cancer (osteosarcoma); external beam radiotherapy; and the radiotherapy of skeletal metastases and soft-tissue sarcomas.
Primary bone is the first bone tissue that appears in embryonic development and in fracture repair. It is characterized by its random position of collagen fibers. In most places in adults this tissue is replaced by secondary bone tissue except, for example, near the sutures of calvara or tooth sockets. The secondary bones have lower amounts of osteocytes so primary bone is much more easily penetrated by x-ray.
Malcolm Sutherland-Foggio was born on April 4, 1998, in Morristown, New Jersey. He is the Founder and Ex Officio Chairman of Make Some Noise: Cure Kids Cancer Foundation, Inc., a 501(c)(3) established to raise funds exclusively for childhood cancer research and increase awareness for these diseases.
John H. Healey is an American cancer surgeon, researcher, and expert in the surgical treatment of benign and malignant bone tumors and other musculoskeletal cancers. He serves as Chair of the Orthopaedic Service and Stephen P. McDermott Chair in Surgery at Memorial Sloan-Kettering Cancer Center (MSKCC), as well as Professor of Surgery at Weill Cornell Medical College, in New York, NY.
Sir Alan William Craft is a British paediatric oncologist and Emeritus Professor of Child Health at Newcastle University. Craft was most notable for work as one of nine founders of the Children's Cancer Study Group, focusing his research on paediatric oncology, especially the epidemiology of bone tumours that further led to an oncology research unit which has been involved in aetiological studies and in particular the role of irradiation in the development of childhood cancer.
A bone sarcoma is a primary malignant bone tumour, a type of sarcoma that starts in the bones. 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.
Elena Huelva Palomo was a Spanish cancer activist, influencer, and writer. Through her regular use of social media, she divulged information about Ewing sarcoma, the type of cancer she was suffering from, to a wider audience, and demanded more investment for cancer research. She was credited with increasing the visibility of childhood bone cancer while dispelling misconceptions and myths about the disease.
