肺的早期鳞状上皮癌指位于支气管壁且没有发生淋巴结及远处转移的鳞癌,其诊断常依赖于支气管镜活检及痰细胞学检查。而CT多用于了解有无淋巴结、远处转移及有无支气管外扩散。为探讨CT对早期肺癌的诊断价值及其局限性,作者对18例早期肺癌的手术病理检查结果与CT表现进行了对照分析研究。本组18例病人,平均年龄69.6岁。16例为单发瘤体,2例有两个瘤体。CT检查前均经支气管镜检查,手术切除,病理证实为早期肺鳞癌,根据肿瘤的不同形态分为低平型与息肉型两种。息肉型表现为支气管内息肉样
Early squamous cell carcinoma of the lung refers to squamous cell carcinoma located in the bronchial wall without lymph node metastasis and distant metastasis. Its diagnosis often depends on bronchoscopic biopsy and sputum cytology. CT is mostly used to understand whether there are lymph nodes, distant metastases, and whether there is extrabronchial proliferation. To investigate the diagnostic value and limitations of CT on early-stage lung cancer, the author conducted a comparative analysis of the pathological findings and CT findings of 18 cases of early-stage lung cancer. This group of 18 patients, the average age of 69.6 years. Sixteen patients had a single tumor and two patients had two tumors. CT examination before bronchoscopy, surgical resection, pathologically confirmed early lung squamous cell carcinoma, according to the different forms of the tumor into two types of low-flat and polypoid. Polypoid bronchial polyps
