Malignant Mesothelioma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Cellular Classification of Malignant Mesothelioma

Histologically, these tumors are composed of fibrous or epithelial elements or both. The epithelial form occasionally causes confusion with peripheral anaplastic lung carcinomas or metastatic carcinomas. Attempts at diagnosis by cytology or needle biopsy of the pleura are often unsuccessful. It can be especially difficult to differentiate mesothelioma from adenocarcinoma on small tissue specimens. Thoracoscopy can be valuable in obtaining adequate tissue specimens for diagnostic purposes.[1] Examination of the gross tumor at surgery and use of special stains or electron microscopy can often help. The special stains reported to be most useful include periodic acid-Schiff diastase, hyaluronic acid, mucicarmine, CEA, and Leu M1.[2] Histologic appearance seems to be of prognostic value, and most clinical studies show that patients with epithelial mesotheliomas have a better prognosis than those with sarcomatous or mixed histology mesotheliomas.[2,3,4]

General Information About Non-Small Cell Lung Cancer (NSCLC)

NSCLC is any type of epithelial lung cancer other than small cell lung cancer (SCLC). The most common types of NSCLC are squamous cell carcinoma, large cell carcinoma, and adenocarcinoma, but there are several other types that occur less frequently, and all types can occur in unusual histologic variants. Although NSCLCs are associated with cigarette smoke, adenocarcinomas may be found in patients who have never smoked. As a class, NSCLCs are relatively insensitive to chemotherapy and radiation therapy...
