Less than 1% of the lung cancer cases from the Surveillance, Epidemiology, and End Results (SEER) Program changed categories as a result of the World Health Organization's revision of histologic classifications of lung tumors. Of the 28,119 microscopically proved lung cancers reported to SEER in 1977-79, 32% were squamous cell carcinoma, 16% were small cell and/or oat cell carcinoma, 27% were adenocarcinoma, 8% were large cell carcinoma, and 5% were other specified types. A further 12% (approximately 3,500 cases) were reported with such nonspecific terms as bronchogenic carcinoma, carcinoma of the lung, and undifferentiated or anaplastic carcinoma. The magnitude of the use of these nonspecific terms showed the need for greater precision in reporting and recording data.
监测、流行病学和最终结果（SEER）项目中，因世界卫生组织对肺肿瘤组织学分类的修订，不到1%的肺癌病例改变了类别。在1977 - 1979年向SEER报告的28119例经显微镜证实的肺癌中，32%为鳞状细胞癌，16%为小细胞和/或燕麦细胞癌，27%为腺癌，8%为大细胞癌，5%为其他特定类型。另有12%（约3500例）报告使用了诸如支气管源性癌、肺癌、未分化或间变癌等非特异性术语。这些非特异性术语的使用频率表明在报告和记录数据时需要更高的精确性。
