LOW GRADE CHONDROSARCOMA OF LONG BONE: THE SURGICAL TREATMENT

Abstract

It is well known that wide resection and reconstruction with modular or composite prostheses is the treatment of choice in high chondrosarcoma of metasepiphyseal bone. Nevertheless there is a debate concerning the treatment of low grade chondrosarcoma, a locally aggressive tumour, similar also histologically to benign lesion. Two different therapeutic options are reported in these lesions: wide resection and intralesion curettage. Between 1995 and 2003 the Authors analysed a series of 37 cases of low grade chondrosarcoma of long bone treated with curettage and local adjuvant, like liquid nitrogen and acrylic cement, if necessary associated with synthesis. The least follow-up was two years. The authors observed 3 local recurrences within the first 12 months from the surgical treatment; and, in every case, an increased grade of malignity was observed at histology. The Authors confirmed that the aggressive intralesional treatment with the use of the local adjuvant like liquid nitrogen and cement, is a valid therapeutic possibility in these lesions, but they confirm that it’s necessary an accurate preoperative diagnosis with also open biopsy for an efficacy treatment.
