Maxillofacial sarcomas are rare tumors, varying according to their type, grade, site of occurrence, response to treatment and prognosis. Approximately 10% of all cases of osteosarcoma, a subtype with a particularly poor prognosis, occur in the head and neck.
During the 35 years from 1963 until 1997, the 25 patients treated for sarcomas at our center were identified and evaluated according to a variety of parameters.
Overall 2- and 5-year survival rates were 72% and 60%, respectively. Sarcomas were found most commonly in the mandible, maxilla and tongue. Survival was not significantly correlated with gender, ethnic origin or histopathological staging, but significant correlation was found between type of sarcoma and survival whilst younger patients had better survival rates.
Advanced facial reconstruction methods may enable the performance of more radical ablative surgery, thereby improving survival outcome for head and neck osteosarcoma patients. Osteosarcoma appears to be as lethal in the maxillofacial region as in the extremities.
颌面肉瘤是罕见肿瘤,根据其类型、分级、发生部位、对治疗的反应及预后而有所不同。骨肉瘤是预后特别差的一种亚型,约10%的骨肉瘤病例发生在头颈部。
在1963年至1997年的35年间,确定了在我们中心接受肉瘤治疗的25例患者,并根据多种参数进行评估。
总体2年和5年生存率分别为72%和60%。肉瘤最常见于下颌骨、上颌骨和舌部。生存率与性别、种族或组织病理学分期无显著相关性,但肉瘤类型与生存率之间存在显著相关性,同时年轻患者的生存率更高。
先进的面部重建方法可能使更彻底的切除手术得以实施,从而改善头颈部骨肉瘤患者的生存结果。骨肉瘤在颌面区域似乎与在四肢一样致命。
