Primary Malignant Fibrous Histiocytoma of the Larynx:a Report of 4 Cases and Review of the Literature

目的:分析原发性喉恶性纤维组织细胞瘤的起源、病理、临床特点及治疗。方法:我院自1990年8月至2000年12月收治4例原发性喉恶性纤维组织细胞瘤患者,均有病理证实,中位年龄为66岁;主要症状是声嘶,呼吸困难,吞咽疼痛。4例均手术治疗,2例行第2次手术治疗(全喉切除术)。3例行术后放疗,采用60Co,6MVX线,放疗剂量为60～62Gy/6周。结果:3例健在,分别已生存11年,4年,3年;1例未放疗者术后复发,颈淋巴结转移,带瘤生存10个月。结论:喉恶性纤维组织细胞瘤具有高度浸润性,易复发,手术加放疗是一种积极有效的措施。
