Head and neck chondrosarcoma: analysis of 16 cases.
OBJECTIVE
Head and neck chondrosarcomas are rare, accounting for less than 12% of all chondrosarcomas. Few studies with larger series approach the clinicopathological characteristics of these tumours. The aim of this study was describe clinical findings, management and outcome of 16 cases of head and neck chondrosarcoma from a single institution.


METHODS
The files of the Cancer Hospital A.C. Camargo were reviewed, and data from patients with head and neck chondrosarcoma were collected.


RESULTS
Mean age was 36 years, with slight male predilection. The most common site affected was maxilla (43%). Surgery was the main modality treatment performed in 10 patients. Overall 5-year survival rate was 56.4%. Although it was not statistically significant, the most important factor affecting overall survival was tumour size.


CONCLUSIONS
Early diagnosis and adequate surgical resection are important to get better survival rates.
