本文对颌骨原发性骨肉瘤８５例、软骨肉瘤１６例和纤维肉瘤１９例进行了临床病理观察和随访。三者发病均以男性多见，发病平均年龄３２～３９岁。预后以骨肉瘤最差，软骨肉瘤最好，纤维肉瘤预后介于二者之间；五年生存率分别为４０．４０％，７０．３７％和５２．２７％。文中讨论了颌骨骨肉瘤、软骨肉瘤和纤维肉瘤的临床病理和生物学行为特点。 In this paper, 85 cases of primary osteosarcoma of the jaws, 16 cases of chondrosarcoma, and 19 cases of fibrosarcoma were reviewed for clinical pathology and follow-up. The incidence of all three men were more common, the average age of onset was 32 to 39 years old. The prognosis was osteosarcoma with the worst, chondrosarcoma was the best, and the prognosis of fibrosarcoma was between the two; the five-year survival rates were 40.40%, 70.37% and 52.27%, respectively. The characteristics of clinicopathological and biological behaviors of osteosarcoma, chondrosarcoma and fibrosarcoma of the jaws are discussed.
