Abstract

In the current study, a 58-year-old male patient presented with recurrent glioblastoma multiforme (GBM). The patient underwent surgical resection, 4 months earlier, followed by radiotherapy and chemotherapy. During the second surgical intervention, tumour tissue and whole blood were sampled and analysed for human cytomegalovirus (HCMV) DNA, immediate early (IE) mRNA and pp65 mRNA. HCMV DNA was detected only in the recurrent tumour tissue but not in the whole blood. Neither IE mRNA nor pp65 mRNA was expressed. Our result suggests HCMV latency in the brain tumour with detectable level of viral DNA. More data are needed to understand the HCMV infection chronology in the brain tumours but our data could be important for further studies of HCMV antigens on the tumour surface and anti-GBM therapy.
