subject: Spontaneous Humoral Immune Response to Mesothelin in Humans [print this page] A total of 12 mesotheliomas (six mixed type and six epithelioid type) and 13 carcinomas (eight adenocarcinomas and five large cell undifferentiated carcinomas) were studied.
The results revealed a clear difference between mesotheliomas and adenocarcinomas: 11 of 12 mesotheliomas showed coexpression of vimentin and cytokeratins in at least 50% of the tumour cells, while in seven of the eight adenocarcinomas none or only a few cells could be seen with this coexpression. In the undifferentiated large cell carcinomas three of five expressed both components, but in less than 25% of the cells. It is concluded that a reliable double immunoenzyme staining of vimentin and cytokeratins can be used as an additional means to distinguish malignant mesothelioma from pulmonary denocarcinoma."
