Extended surgical curettage and bone graft or artificial plastic.Skeletally immature patients is recommended to fill the bone defect with polymethylmethacrylate, this skeletal growth whileallowing the tumor cells are destroyed. In older patients whereskeletal development is not a problem bone grafting isrecommended for small lesions. For large lesions and cementreconstruction is necessary.
Filling the defect with polymethylmethacrylate is recommendedafter removal of recurrent lesions.
Block or wide excision is reserved for advanced tumors that cannot be treated by intralesional excision. The rate of recurrence afteren bloc excision is 7%. Options include reconstruction after wideexcision and reconstruction with structural allogrefareaendoprosthesis or allograft prosthetic.
Prognosis:
The prognosis is generally correlated with lesion size, anatomicallocation and histological grading of the site. Patients with axiallesions were most negative prognosis from those with lesions of the appendicular skeleton. 5-year survival rate for patients withgrade 1 lesions is 90%, the rate dropped to 29% for those withgrade 3 tumors. Grade 1 lesions do not metastasize. Metastaticextension typically is most frequently associated pulmonary lesionsof grade 3. Extending through the lymph nodes is more frequent inchondrosarcoma than in other bone neoplasms. TumorRecurrence after surgery occurs in 5-10 years. Recurrentchondrosarcoma is more aggressive than the primary, and thehistological grading is increased.
