NON-SMALL CELL LUNG CANCER PATHOLOGY

 
Is A-NSCLC from heterogeneous group of histological types, or met most frequent
types are adenocarcinoma, squamous cell carcinoma, large cell carcinoma, Sarcomatoid carcinoma and adenosquamous carcinoma (3). Good for all colon cancer, lung cancer nearly 40%. According to whether 2004 World Health Organization classification, adenocarcinoma Can Be distinction In Big Five subtypes: acinar, papillary, vast, met with mucin production, bronchioloalveolar (BAC), and mixed adenocarcinoma (3). In most adenocarcinomas (~90%) are heterogeneous, consisting of two from several of the histological subtypes SO categorized as en mixed subtype (20). When tumor cells grown in pure A- Without mode lepidic The proof of the Invasion, Are they regarded as a BAC (21). Strict definition of BAC has said unfortunately AS-Ware is uniformly non-invasive tumors are not Applied and pathologists met mixed tumors often different labels Growth rates of ALS or lepidic of adenocarcinoma tumors met BAC BAC Functions. This significant inconsistency of terminology has led to confusion. Squamous cell carcinoma is good for all of about 30% of lung cancers. Most squamous cell carcinomas in the long (~ 70%) was that present central lung tumors (22). Or tumor can grow up big and then cavitate A-Mass, and ost lung cavitation cancers are squamous cell carcinomas (23). CEL is Good Great carcinoma about 9% of all lung cancers, they Have A spectrum of morphologies, and whether visitors are met with most cells and many nuclei Great Big met prominent nucleoli cytoplasm (23). This carcinomas Also some specific variants, including cell size and neuro-endocrine carcinomas (LCNEC).
