气管腺样囊性癌是气管低度恶性肿瘤。呼吸困难和喘鸣是最常见的临床症状。胸片、气管镜、CT和MRI是常用的检查手段。气管腺样囊性癌镜下分为三个亚型:腺管状、筛状、实体状。文献分析提示纵隔淋巴结转移率19.0%~30.8%,远地转移率18.5%~44.0%,肺转移最多见。46.0%~93.1%患者行手术治疗方法,术后放疗32.5%~81.2%,术后5年生存率52.4%~91.0%,未手术5年生存率33.3%~53.0%。手术是首选治疗,手术切缘阳性较多见。手术是否根治性是预后因素,对于R1或R2切除术后的辅助性放疗可能是预后影响因素,对于不能手术的患者放射治疗是首选治疗。
Tracheal adenoid cystic carcinoma is a low-grade tracheal malignancy. Dyspnea and wheezing are the most common clinical symptoms. Chest radiography, bronchoscopy, CT and MRI are commonly used methods of examination. Tracheal adenoid cystic carcinoma microscope is divided into three subtypes: glandular tube, sieve-like, solid-like. Literature analysis showed that mediastinal lymph node metastasis rate of 19.0% to 30.8%, distant metastasis rate of 18.5% to 44.0%, the most common lung metastasis. Surgical treatment was performed in 46.0% -93.1% of patients. The postoperative radiotherapy was 32.5% -81.2%. The 5-year survival rate was 52.4% -91.0%. The 5-year survival rate was 33.3% -53.0%. Surgery is the preferred treatment, surgical margin positive more common. Radical surgery is a prognostic factor for the R1 or R2 after adjuvant radiotherapy may be prognostic factors for patients with inoperable patients is the preferred treatment of radiation therapy.
