If Ted Kennedy’s cancerous lesion is a glioblastoma multiforme, the most common kind of brain tumor, it may have been caused by a virus from the herpes family.

A type of herpes virus called human cytomegalovirus (CMV) is found in up to 80 percent of Americans, though the virus normally produces very few clinical symptoms, is dormant, and usually undetectable in most people. However, more than 80 percent of patients newly diagnosed with the brain cancer glioblastoma multiforme (GBM) exhibit detectable CMV in their blood as well as in their tumors. The Duke team thought this might provide an opportunity to target brain tumors by going after the virus.
