摘要
文章报告了经病理检查证实的111例骨肉瘤,平均年龄为24.2岁,发病高峰年龄为16～20岁(35.2％);好发于股骨远端(41.7％)、胫骨近端(26.9％)和肱骨近端(9.3％)。主要X线表现有骨内成骨(74.1％)、骨内骨破坏(66.7％)、骨外软组织肿块(88.0％)、骨外瘤骨(84.3％)、Codman三角(42.6％)和层状骨膜反应(32.4％)。长骨干骺端的肿瘤越过骨骺板而侵犯骨骺者占45.5％,长骨端的肿瘤侵犯关节者占14.7％。骨肉瘤的术前X线诊断正确率为81.8％。
One hundred and eleven eases of pathologically proved osteosarcoma were analyzed. The average age was 24.2 years. The age of peak incidence was in 16～20 years (35.2％). Osteosareomas were mostly occurred in distal end of femur (41.7％), and next in proximal end of tibia (26.9％) and proximal end of the humerus (9.3％). The important x-ray features of osteosarcoma were intraosseous ossification (74.1％), intraosseous bone destruction(66.7％), extraosseous soft tissue mass (88.0％),extraosseous tumor bone formation (84.3％), Codman's triangle (42.6％) and laminated periosteal reaction(32.4％). The metaphyseal lesions of the long bones exceeded the epiphyseal plate and invaded the epiphysis were found in 45.5％. The lesions in the end of the long bones invaded the joints occurred in 14.7％. The correct rate of preoperative x-ray diagnosis of the osteosarcoma was 81.8％.
