48例鼻腔鼻窦肉瘤的临床分析

目的：探讨鼻腔鼻窦肉瘤的临床表现、诊断、治疗及预后，以提高对鼻腔鼻窦肉瘤的诊疗水平。方法：回顾性分析48例鼻腔鼻窦肉瘤患者的临床资料。结果：鼻腔鼻窦纤维肉瘤4例，恶性纤维性组织细胞瘤3例，脂肪肉瘤4例，平滑肌肉瘤5例，横纹肌肉瘤5例，骨肉瘤2例，软骨肉瘤3例，恶性黑色素瘤4例，非霍奇金淋巴瘤4例，浆细胞肉瘤1例，恶性神经鞘膜瘤5例，嗅神经母细胞瘤5例，血管肉瘤3例，综合治疗后随访，1，3，5年生存率分别为62．5％，46．7％，35．7％。结论：鼻腔鼻窦肉瘤不易明确诊断，结合免疫组织化学有助于诊断，对肿瘤易复发及全身转移者，综合治疗可提高生存率。

Clinical analysis of 48 cases sarcoma in nasal cavity and sinuses

Objective:To enhance the level of diagnose and treatment of sarcoma in nasal cavity and sinuses by studying the clinical features,diagnosis and treatment of 48 cases sarcoma in nasal cavity and sinuses.Method:Forty-eight cases sarcoma in nasal cavity and sinuses treated from 1995 to 2000 were analyzed retrospectively.Result:Fibrosarcoma in 4 cases, maglinant fibrous histiocytoma in 3 cases, liposarcoma in 4 cases, leiomyosarcoma in 5 cases, rhabdomyosarcoma in 5 cases, osteosarcoma in 2 cases, chondrosarcoma in 3 cases, malignant melanoma in 4 cases, non-hogkin's in 4 cases, extramedullary plasmacytoma in 1 cases, Schwannoma in 5 cases, esthesioneuoblastoma in 5 cases, angiosarcoma in 3 cases. Following-up after synthetic treatment, the 1,3,5 year survival rates were 62.5%, 46.7%, 35.7% respectively.Conclusion:Sarcoma in nasal cavity and sinuses is not easy to diagnose definitely, immunohistochemistry is helpful for pathological diagnose. It's easy to recurrent and metastasis and it's beneficial to improve prognosis with synthetic treatment.
