Non-small-cell lung cancer (NSCLC), which includes adenocarcinoma, squamous cell carcinoma and large cell carcinoma, accounts for 80- 85% of all lung cancers.
This is called Barrett's esophagus - or Barrett's metaplasia, and the cylindrical epithelium has a greater risk of degenerating into a particular type of esophageal cancer, called adenocarcinoma.
Well-differentiated tumors with adenocarcinoma or squamous cell carcinoma morphology can be diagnosed by routine light microscopy, without the need for IHC.
Sub-solid nodules will require longer follow-up than solid nodules as they may represent premalignant adenocarcinoma in situ or minimally invasive adenocarcinoma.
NOS carcinomas that stain with adenocarcinoma markers are classifed as 'NSCLC, favor adenocarcinoma'; tumors that stain with squamous markers are classified as 'NSCLC, favor squamous cell carcinoma'.
带有腺癌标志物染色的 NOS 癌被归类为“NSCLC,有利腺癌”;用鳞状细胞标记染色的肿瘤被归类为“非小细胞肺癌,有利鳞状细胞癌”。
