肺癌是人类常见的恶性肿瘤,在肺癌各种组织类型中,腺癌是主要类型之一。近年研究证实[1],腺癌已逐步取代了鳞状细胞癌的地位。细支气管肺泡癌(Bronchioloalveolarlung carcinoma,BAC)为腺癌的一个特殊类型,与普通的腺癌不同,它分为3个亚型:(1)粘液上皮型(或称分泌型),(2)细支气管上皮型(或称非分泌型),(3)炎性硬化型(或称低分化型)。BAC的肿瘤细胞生长于原有的肺泡壁上,保持肺泡结构为其特征。与其它支气管源性肺癌相比,BAC具有其固有的组织起源和形态特征。追溯其组织起源、发病机理,
Lung cancer is a common malignant tumor in human beings. It is one of the main types of lung cancer in various tissue types. Recent studies confirm [1], adenocarcinoma has gradually replaced the status of squamous cell carcinoma. Bronchoalveolar carcinoma (BAC) is a special type of adenocarcinoma that, unlike normal adenocarcinomas, is divided into three subtypes: (1) mucoepidermoid (or secretory), (2) fine Bronchial epithelial (or non-secreted), (3) inflammatory sclerosis (or poorly differentiated). BAC tumor cells grow in the original alveolar wall, maintaining the alveolar structure as its characteristics. BAC has its inherent tissue origin and morphological features compared to other bronchogenic lung cancers. Trace its organization origin, pathogenesis,
