Abstract

Conventional osteosarcoma is a high-grade malignant tumor characterized by the production of osteoid matrix by malignant osteoblasts. It typically affects the long bones of children and adolescents. Treatment includes systemic chemotherapy and a local surgical approach with wide resection. Recent advances in oncology concepts, imaging, surgical planning, and cancer treatment protocols allow for improved survival and a higher limb preservation rate. This paper addresses the current status regarding the incidence, pathology, treatment, and prognosis of conventional high-grade osteosarcoma.

Keywords: neoplasms; ostesarcoma; sarcoma.
