[Immunohistochemical study on the presence of CEA in primary brain tumors. Preliminary note]. / Studio immunoistochimico sulla presenza del CEA nei tumori cerebrali primitivi. Nota preliminare.

The immuno peroxidase histochemical technique produced optic microscopic evidence of CEA (carcinoembryonic antigen) in 19 out of 42 (42.25%) brain tumours including 12 astrocytomas, 6 glioblastomas and 1 ependymoma. The possibility of identifying CEA in such tumours is extremely interesting in view of the fact that CEA is currently the antigen most commonly studied and utilised in various types of non-cerebral cancers.
