外耳道腺样囊性癌临床分析[论著]

目的　探讨外耳道腺样囊性癌的临床特点、诊断和治疗方法。方法　回顾性分析2008年1月至2020年12月在扬州大学附属苏北人民医院收治的6例外耳道腺样囊性癌患者临床资料,分析其临床症状、治疗及随访结果。2例行乳突扩大切除术,3例行颞骨次全切+腮腺浅叶切除+颞肌修复术,1例行颞骨次全切+腮腺浅叶切除、深叶部分去除术+颞肌修复术。结果　6例患者术后随访2~8年,随访5年以上者5例,术后复发1例。结论　外耳道腺样囊性癌不易及时确诊,肿瘤生长缓慢,容易复发和发生肺部转移。手术治疗结合术后辅以放疗可延长患者生存期、降低复发,是治疗外耳道腺样囊性癌的有效方法。

An immunohistochemical study of adenoid cystic carcinoma of the external auditory canal

Summary Specimens from five cases of adenoid cystic carcinoma of the external auditory canal were studied by immunohistochemical staining, and findings were compared with those from adjacent non-neoplastic tissues containing ceruminous glands. In the ceruminous gland, cytokeratin showed diffuse positive staining, while myoepithelial cells were stained for smooth muscle actin, desmin, S-100 protein and vimentin. The epithelial markers used were cytokeratin, carcinoembryonic antigen and secretory component and stained at various densities the inner cells of the tubular component and ductlining cells in the cibriform component of tumor tissues. In contrast, the muscular markers, smooth muscle actin and desmin, and the mesenchymal marker, vimentin, were positive in the outer cells of the tubular component and in the cyst-lining cells of the cribriform component. S-100 protein immunoreactivity showed pradoxical results; positive findings occurred in the myoepithelial cells of the ceruminous glands and in the inner cells of the tubular component and duct-lining cells of the cribriform component of the tumor. Present findings demonstrate that adenoid cystic carcinoma of the external auditory canal had dual epithelial and myoepithelial differentiation and can mimic the ceruminous glands of the auditory canal.     

颞骨次全切除术治疗外耳道腺样囊性癌的疗效分析

目的 探讨颞骨次全切除术在外耳道腺样囊性癌的临床应用效果。方法 回顾性分析2015—2019年收治的8例外耳道腺样囊性癌患者的临床资料,其中男2例,女6例;年龄33~76岁,平均年龄55.6岁。耳痛7例,外耳道肿块、耳溢液、听力下降各6例,面瘫1例;从最初出现症状到确诊平均为2.75年,5例曾被误诊,3例曾被误治手术;6例行颞骨次全切除+腮腺浅叶切除术,2例行颞骨次全切除+全腮腺切除术。结果 围手术期内1例患者出现局部切口感染,1例出现脑脊液漏。全部患者平均随访4.34年;6例患者无瘤存活;1例复发患者于我院二次手术后3年再次出现局部复发伴肺转移,接受放射治疗,目前带瘤生存;1例患者术后随访3.5年死于其他疾病。结论 外耳道腺样囊性癌早期症状不典型,容易误诊;确诊后应实施颞骨次全切除术以达到彻底切除肿瘤目的,术中应同时处理腮腺;术后放疗也是一种可选择的补充治疗手段。

Adenoid cystic carcinoma of the external auditory canal

Objective/Hypothesis: To describe the clinical history and outcome of patients with adenoid cystic carcinoma (ACC) of the external auditory canal (EAC). Study Design: Retrospective case series. Methods: A search of our institution's tumor registry identified 22 patients with ACC of the EAC. Both clinical histories and pathology slides, when available, were reviewed. Results: The mean age at diagnosis was 42 years (median, 38.5 years), and the most common presenting complaints were otalgia and ear canal mass. Nine patients (41%) developed recurrences at a mean of 8 years (median, 8 years) after initial diagnosis, six died of ACC, and three were living with distant metastases at their last follow-up. The mean duration of symptoms at the time of diagnosis was 7.7 years (range, 2–30 years) for patients who developed a recurrence after treatment vs. 1.2 year (range, 0–2 years) for patients who remained disease-free (P = .137). Every patient who had recurrent disease reported a duration of symptoms of ≥2 years (P = .013), and every patient with a duration of symptoms >2 years recurred (P = .002). There was a trend for more local recurrences after limited resection (P = .061). Conclusions: ACC of the EAC often recurs many years after definitive treatment. Although our sample size was too small to make definitive conclusions, we recommend aggressive local therapy with lateral temporal bone resection and adjuvant postoperative radiotherapy. In addition to successful local therapy, early diagnosis may be the only other effective means of preventing distant metastases.

Diagnosis and treatment of carcinoma in external auditory canal

ObjectivesTo evaluate outcomes in treating carcinoma of external auditory canal (EAC) and to analysis factors which effect the prognosis of this disease.MethodsA retrospectively review of 16 patients treated for carcinoma of EAC at our department between April 2000 and April 2014 was conducted. All patients underwent surgical treatment and the diagnosis confirmed by pathological examination.ResultsThere were adenoid cystic carcinoma (ACC) in 8 patients, squamous cell carcinoma (SCC) in 5 patients, adenocarcinoma (AC) in 2 patients, and verrucous carcinoma (VC) in 1 patient. The tumors were classified as Stage I in 4 cases, Stage II in 2 cases, Stage III in 3 cases, and Stage IV in 7 cases. Five patients underwent extensive tumor resection (ETR), 2 patients underwent lateral temporal bone resection (LTBR), 5 patients underwent modified LTBR, 2 patients underwent subtotal temporal bone resection (STBR), and 2 patients underwent only open biopsy. Besides, adjunctive procedures, including neck dissection, parotidectomy and pinna resection were performed when indicated. Ten patients received postoperative radiotherapy. By the end of follow up, two patients had died of their disease, 2 lost to follow up, 2 survived with the disease, and the rest survived disease-free. The median follow-up period was 24 months.ConclusionComplete tumor resection appears to be an effective treatment for carcinoma of the EAC. Patients with SCC seem to have worse prognosis than those with ACC. Radiation therapy seems less effective for the disease than surgical treatment.

目的 探讨外耳道腺样囊性癌的临床病理特点，总结疗效。方法 回顾性分析1985-2001年收治的8例外耳道腺样囊性癌患者的临床资料。结果 8例患者中行局部肿瘤切除2例；行外耳道袖状切除加腮腺浅叶切除2例；行肿瘤切除加扩大乳突根治3例（1例手术5次，最后1次行颞骨次全切除术）；行耳廓全切除加颞骨次全切除术1例。后4例术后辅以放疗。随访5～15年，2例健在，2例6年后肺转移带瘤生存，2例8年后死于肺转移，2例失访。结论 外耳道腺样囊性癌早期确诊和彻底手术是延长患者生命的关键。肿瘤易发生肺转移，远期预后不佳，提倡综合治疗。     

外耳道腺样囊性癌临床分析

目的 探讨外耳道腺样囊性癌的治疗方法与影响预后的相关因素.方法 对解放军总医院耳鼻咽喉头颈外科医院1988--2004年收治的19例外耳道腺样囊性癌患者的临床资料进行分析.依据Pittsburgh外耳道癌分类法,T1期5例,T2期2例,T3期6例,T4期6例.T1和,12期病例行局部切除,T3和T4期病例行乳突根治术或颞骨切除术.术后予以足量放疗.复发病例伴远处转移单灶者行手术治疗,远处多灶转移者行放疗.结果 19例病例术后随访时间6个月～19年,随访时间中位数44个月,随访5年以上者8例.12例复发,7例远处转移,4例死亡.初次切缘肿瘤细胞阳性的4例患者足量放疗后全部复发.复发患者有9例进行了2次以上手术治疗,8例进行了3次以上手术治疗,4例进行了4次手术治疗.结论 外耳道腺样囊性癌起病隐匿,易复发,可长期带瘤生存.首次手术应扩大切除范围,确保切缘肿瘤细胞阴性.术后辅以足量放疗.复发病例可多次手术治疗,延长生存期.多次局部复发后易发生远处转移.远处转移是主要死亡原因.
