Periosteal Osteosarcoma: A Review of 17 Cases with Mean Follow-upof 52 Months

[摘要] Purpose:Periosteal osteosarcomas are rare cartilage-rich bone tumours characterized by a juxtacortical eccentric positionand are normally regarded oncologically as of intermediate to high grade.Their low incidence is mirrored by a small numberof reported cases in the world literature. While there is general agreement that wide surgical excision is required, there is apaucity of evidence regarding adjuvant therapy. Previous reports have not indicated any consistent approach to this to allowappraisal.Patients and methods:We report 17 cases treated at our centre over 16 years. Our policy was to use chemotherapy when thetumour showed any features of high grade.Results:To date, no deaths have resulted from recurrence or metastasis of the tumour although there have been two deathsfrom other causes.Discussion:Comparison of survival with existing studies is made to draw conclusions regarding future treatment of this conditionin terms of surgical and adjuvant approaches.
