【摘要】 目的 评估耳或颞骨恶性肿瘤侧颞骨切除术(LTBR)治疗的临床效果。方法 回顾2000-2007年接受LTBR治疗的耳或颞骨恶性肿瘤患者病历。结果 35例患者中,平均62.7岁,其中包括鳞状细胞癌(SCC)20例,基底细胞癌(BCC)7例,腺样囊性癌(ACC)7例,腺癌1例。5年生存率(OS)、疾病特异生存率(DSS)和无瘤生存率(DFS)分别为77%、79%和52%。完全切除能够改善OS、DSS和DFS(均P<0.004)并减少局部复发(P<0.001)。结论 耳和颞骨恶性肿瘤患者中,上-前部切除包括LTBR结合术后放射的治疗有效。完全切除所有病灶能够改善生存率并减少复发。

【Abstract】 Objective To evaluate clinical outcomes following lateral temporal bone resection(LTBR)for management of m alignancies involving the ear or temporal bone.Methods A retrospective medical record review was performed on patients receiving LTBR for management of m alignancies involving the ear or temporal bone between 2000 and 2007.Results In this group of 35 patients,the mean age was 62.7 years,with tumor histopathologies including squamous cell carcinoma(SCC,20),basal cell carcinoma(BCC,7),adenoid cystic carcinoma(ACC,7),and adenocarcinoma(1).The 5-year overall survival(OS),disease-specific survival(DSS),and disease-free survival(DFS)were 77%,79%,and 52%,respectively.Complete resection resulted in improved OS,DSS,and DFS(P<0.004 for each)and reduced local recurrence(P<0.001).Conclusion In patients with carcinomas of the ear and temporal bone,upfront excision including LTBR is an effective management when combined with postoperative radiation therapy.Complete removal of all disease may improve survival and decrease recurrence.

侧颅底恶性肿瘤的成功治疗需要应用多学科方法,包括耳鼻喉科、外科、放射科和肿瘤科。影响该区域的肿瘤多源于耳廓或外耳道(EAC)皮肤,或近旁的腮腺或耳廓周围皮肤[1]。由于接近侧颅底区、硬脑膜和主要神经血管结构,在确定适当的治疗计划时必须采取系统化处理方法。随着术前检查和影像技术的改进,不同手术径路均以肿瘤学最安全,同时最小损伤临近重要的神经血管结构为目标。当肿瘤很小并仅限于EAC软组织时,可进行切除活检。然而在处理更具侵袭性肿瘤就需要颞骨切除。侧颞骨切除术(LTBR),包括骨EAC、鼓膜、锤骨和砧骨的切除,内侧界线限定在砧镫关节水平,骨迷路和面神经保留。大部颞骨切除术切除范围扩展至听软骨囊,但保留岩骨尖。全颞骨切除移除整个颞骨。侧颞骨切除术被认为是耳后、外耳或EAC肿瘤,或当侵润EAC后部或乳突皮质,而未累及中耳乳突气房时适合的手术径路[2]。本研究评估了EAC、耳廓、颞骨或邻近腮腺肿瘤患者行侧颞骨切除术治疗后存活和复发结果,同时评价不同肿瘤外科和病理学变量以确定其是否影响这些结果。……
