Relationship between surgical procedure and outcome for patients with grade I chondrosarcomas.
OBJECTIVE
To evaluate the oncological outcome of patients with grade I chondrosarcomas according to the type of surgical treatment performed, since there is still controversy regarding the need for aggressive resections to reach a successful outcome.


METHODS
The records of 23 patients with grade I chondrosarcomas were reviewed. The mean age was 38.4 years, ranging from 11 to 70 years; 52% were men and 48% were women. The femur was the site of 13 tumors. The tumors were staged as IA (17, 74%) and IB (6, 26%). Regarding tumor location, 74% (17) were medullary, 22% (5) were peripheral, and 4% (1) was indeterminate. Tumor size ranged from 2 to 25 cm, mean 7.9 cm. Regarding the surgical procedure, 11 patients underwent intralesional resection, 9 patients underwent wide resection, and 3 underwent radical resection. The follow-up period ranged from 24 to 192 months.


RESULTS
None of the patients developed local recurrence or metastases; 7 patients had other general complications.


CONCLUSIONS
This data supports the use of less aggressive procedures for treatment of low-grade chondrosarcomas.
