目的 总结食管腺鳞癌的临床特点、诊断、治疗和预后.方法 回顾性分析经病理确诊和治疗的22例食管腺鳞癌患者临床资料,应用Kaplan-Meier法进行生存分析.结果 22例食管腺鳞癌患者的临床症状、影像学表现和内窥镜下所见与食管鳞状细胞癌(鳞癌)相似.19例患者术前内窥镜活检误诊为鳞癌.单纯手术治疗16例,手术+术后放疗3例,单纯放疗、序贯化放疗和同期化放疗各1例.本组总的1、3、5年生存率分别为67.6%、33.8%和18.1%,中位生存时间为24.5个月.结论 食管腺鳞癌少见,易误诊,宜采用以手术为主的综合治疗,预后评价不一.

Objective This study was to review the clinical features, diagnosis, treatment, and prognosis of esophageal adenosquamous carcinoma (ASC). Methods Clinical data of 22 patients with pathologically confirmed esophageal ASC, treated in the Cancer Center of Sun Yat-sen University from May 1988 to April 2006, were retrospectively analyzed. The survival analysis was performed using Kaplan-Meier method. Results Of 4208 patients diagnosed as esophageal cancer during the same time in our center, only 22 had esophageal ASC, accounted for 0.52%. The median age of the 22 cases was 60 years (range, 42 to 69 years). Esophageal ASC showed similar clinical symptoms, radiological and endoscopic features to esophageal squamous cell carcinoma (ESCC). Nineteen cases were preoperatively misdiagnosed as ESCC by endoscopic biopsy. Among the 22 patients, 16 were treated by surgery alone, 3 by surgery plus postoperative radiotherapy, and the remaining 3 by radiotherapy, sequential chemoradiotberapy and concurrent chemoradiotherapy, each in one case, respectively. The overall 1-,3-and 5-year survival rates were 67.6%, 33.8% and 18.1%, respectively, with a median survival time of 24.5 momths. Conclusion Esophageal adenosquamous carcinoma is a rare esophageal disease and prone to be misdiagnosed as esophageal squamous cell carcinoma. Initial surgical treatment combined with other therapies is suggested. The prognosis of esophageal adenosquamous carcinoma has not yet been well established.
