Purpose: Osteosarcoma of limbs shows excellent therapeutic results due to development of diagnostic and treatment methods. However, osteosarcoma of pelvic bone is known to have lower incidence than those of limbs and poorer prognosis. This study is performed to research the diagnosis, treatment, treatment outcomes, and complications of osteosarcoma of pelvic bone and propose standards for adequate treatment. Objective and Method: 16 cases that were diagnosed as osteosarcoma of pelvic bone from January 1988 to October
