目的 :探讨肺腺鳞癌的影像表现与病理学的关系。材料与方法 :收集10年来2所医院经手术切除及病理证实的18例。男16例 ,女2例。年龄39～71岁。主要症状 :咳嗽 ,痰中带血 ,胸痛 ,气促 ,发热与全身痛。主要体征 :锁骨上淋巴结肿大 ,骨转移 ,胸水。18例有胸片 ,8例行胸部CT检查。结果 :手术治疗7例 ,取出37个淋巴结均阳性。放、化疗11例。在镜下按两种肿瘤的任何一种必须占全部肿瘤的20 %以上的标准诊断。本组以瘤内腺癌含量<40 % ,40 %～60 % ,>60 %分3组 ,结果<40 %6例 ,40～60 %7例 ,>60 %5例。影像学表现为周围型10例 ,中央型8例。单发17例 ,多发1例 ,8例中央型腺鳞癌合并肺不张大小平均4.88～6.90cm ,10例周围型腺鳞癌肿块大小平均4.05～5.05cm。结论 :据报道发病率大约占10 % ,发病率与分型标准、取材多少有关。认为瘤内腺癌成分与影像学所表现的肿瘤分型、部位、形态、大小、边缘、密度无明显的关系。
Objective: To investigate the relationship between the imaging and pathology of lung adenosquamous carcinoma. Materials and Methods: Eighteen patients were confirmed by surgery and pathology in two hospitals in the past 10 years. 16 males and 2 females. Age 39 ~ 71 years old. The main symptoms: cough, bloody sputum, chest pain, shortness of breath, fever and generalized pain. The main signs: supraclavicular lymph nodes, bone metastases, pleural effusion. 18 cases of chest radiography, 8 cases of chest CT examination. Results: Surgical treatment of 7 cases, removed 37 lymph nodes were positive. Radiotherapy and chemotherapy in 11 cases. Any one of the two tumors under the microscope must account for more than 20% of the standard diagnoses of the entire tumor. This group of tumor in the adenocarcinoma <40%, 40% ~ 60%,> 60% divided into 3 groups, the results of <40% in 6 cases, 40 ~ 60% in 7 cases,> 60% in 5 cases. Imaging findings were peripheral type in 10 cases and central type in 8 cases. Seventeen cases were single and 1 case was multiple. The average size of antral squamous cell carcinoma with atelectasis was 4.88 ~ 6.90cm in 8 cases. The average size of the surrounding adenosquamous carcinoma in 10 cases was 4.05 ~ 5.05cm. Conclusion: It is reported that the incidence rate is about 10%. The incidence rate is related to the standard of type classification and the number of samples taken. It is considered that there is no obvious relationship between the components of adenocarcinomas and the tumor types, locations, forms, sizes, margins and densities of the tumors.
