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]

Lung Cancer Clinical Trials

Major drug companies continually research and develop new medications and treatments, which must be shown to be safe and effective before doctors can prescribe them to patients. Through lung cancer clinical trials, researchers test the effects of new drugs on a group of volunteers with lung cancer. Following a strict protocol and using carefully controlled conditions, researchers evaluate the investigational drugs under development and measure the ability of the new drug to treat lung cancer, its...
