mesothelioma markers pathology outlines

Mesothelioma tumor markers tumor markers are substances made by either tumor cells or other types of cells when cancerous and certain non cancerous conditions occur within the body. The best discriminators among the antibodies considered to be negative markers for mesothelioma are cea moc 31 ber ep4 bg 8 and b723.

Mesothelioma Tumor Markers

Once mesothelioma has occurred there is no effective treatment.

Mesothelioma markers. Immunohistochemistry for mesothelioma is still developing as a science and different pathologists have experience with using different. Sarcomatoid mesothelioma is the rarest cell type and the most difficult to treat. The international mesothelioma interest group identified calretinin cytokeratin 56 wt 1 protein podoplanin and mesothelin as some of the most useful mesothelioma markers.

A panel of four markers two positive and two negative selected based upon availability and which ones yield good staining results in a given laboratory is recommended. Recently researchers have developed testing to screen for the presence of tumor markers within the tissue blood and urine of patients who are at risk for cancer. There is therefore an urgent need to identify mesothelioma tumor markers and a method for the early diagnosis of mesothelioma using these markers.

The incubation period of asbestos related mesothelioma is estimated to be approximately 3040 years. Pathologists may test for podoplanin another immunohistochemical marker when sarcomatoid mesothelioma is suspected. For immunohistochemical markers we selected the value closest to the 10 cut off according to the percentage of cells exhibiting staining as it is a frequently used value in immunocytology and implies that samples were considered positive for the marker if at least 10 of malignant mesothelioma cells were immunohistochemically stained.

Only about 31 percent of sarcomatoid cases test positive for calrentinin.
