PDF: Prognostic factors in patients with Jaw Sarcomas


The aim of this study was to identify the prognostic factors related to the survival of patients with sarcomas of the jaw treated in the Dr. Eduardo Caceres Graziani National Institute for Neoplastic Diseases, Lima, Peru.


Sarcomas of the jaws (JS) are infrequent, accounting for about 1% of all the malignant tumors that occur in the oral and maxillofacial region.

These sarcomas are highly aggressive and as such require an accurate diagnosis and therapy to be treated effectively.

Prognostic factors for sarcomas are not well-known, specifically regarding the jawbones. There are some studies that present data on osteosarcomas of the jawbones or data on head and neck sarcomas, but these studies are far from comprehensive.



Studies such as that by Patel et al. reviewed the records of 44 patients with osteogenic head and neck sarcomas and found, at 3 and 5 years, overall survival rates of 81% and 70%, respectively. 

In this study, only the surgical margins were correlated significantly to survival prognosis.
