Primary bone tumors

Primary malignant bone tumors are rare with an estimated frequency is about 1,5-2% of all malignant tumors. The diagnosis and management of these neoplasms require multidisciplinary team approach, which includes orthopaedic surgeons, radiologists, pathologists and oncologists. With this approach and modern treatment 5-year survival of osteosarcoma and Ewing’s sarcoma is 70 and 60% respectively. The major advancements over the past few years in orthopaedic pathology are molecular studies, including genetic and immunoperoxidase studies. Newer surgical techniques, minimally invasive surgical procedures, tumor chemotherapy, bisphosphonates are new advancements.
