[Osteosarcoma of maxillofacial area: a clinicopathological study of 61 cases]
1Department of Oral Pathology, School of Stomatology, Shanghai Second Medical University, Shanghai 200011, China.
Objective:
To study the clinicopathology of osteosarcoma in oral and maxillofacial region.
Methods:
Clinical, histopathological features of 61 cases of osteosarcoma in oral and maxillofacial region were studied.
Results:
The ratio of male to female was 1.26:1, with the mean age 39.8. 32.8% cases were occurred in maxilla and 57.4% cases in mandible. Histologically 55.7% were osteoblastic, 16.4% were chondroblastic and 21.3% were fibroblastic. All tumors presented common histological feature that the neoplastic cells produced neoplastic bone. The recurrence rate of the tumor was 39.1% and the metastasis rate to lung was 8.7%.
Conclusions:
Oral and maxillofacial osteosarcoma was most frequently occurred in mandible. There was no significant difference in patient's gender. Patients were about 10 years older than those suffered the tumor in long bone. Osteoblastic type was the most commonly occurred histological type. The recurrence rate of the tumor was relatively high and the metastasis rate to lung was low. It seems that the tumor had good prognosis than osteosarcoma of long bone.
