Brief Summary:
The purpose of this study is to investigate if treatment of CMV infection by antiviral drug Valcyte (R) affects the clinical outcome of glioblastoma multiforme in patients with local CMV infection in tumor tissue. The investigators' hypothesis states that CMV infection promotes tumor development and disease progression and inhibits immune responses against the tumor.
