Ganciclovir
Ganciclovir has also been used with some success in treating "Human herpesvirus 6" infections.
Human herpesvirus 6
HHV-6 has been detected in lymphomas, leukemias, cervical cancers, and brain tumors. Various medulloblastoma cell lines as well as the cells of other brain tumors have been demonstrated to express the CD46 receptor. Viral DNA has also been identified in many other non-pathological brain tissues, but the levels are lower.
