Abstract
BACKGROUND
Sarcomas constitute 1% of all malignancies, but 10% occur in the head and neck (HN), and they are poorly understood. We present a large series of Soft Tissue HN sarcomas in Mexican patients with survival analysis.
STUDY DESIGN
This is a retrospective study of cases in a cancer hospital.
METHODS
Review of files and pathology material. Literature review.
RESULTS
We analysed 108 patients (55 men / 53 women). The age at presentation was 37 years. The original diagnosis changed in nine cases (8.3%). The most common subtype was rhabdomyosarcoma. Ninety percent of tumours were deep, 91% were high grade, 44% had metastasis, 63% measured >5 cm, overall 5-year survival (5 y-OS) was 48%, and histological high grade was associated with poor survival (p = 0.026).
CONCLUSION
Sarcomas of the HN are rare. The most affected sites were paranasal sinuses. The majority of tumours were deep, > 5 cm and high grade, 50% had metastasis, the 5 y-OS was 48% and the only independent factor associated with 5 y-OS was histologic grade.
