For definitive diagnosis, immunohistochemical staining of biopsy material for epithelial cell adhesion molecule (EPCAM) and Vimentin (VIM) have been used to discriminate mesothelioma from other lung cancers [9], [10], however more recently a microRNA based test with a higher accuracy has been developed and made available to doctors [11]. This evidence concerns the gene EPCAM and mesothelioma.
