HHV-6, EBV and CMV found in GI tract cancers

A group from Washington University used a bioinformatics system called VirusScan to analyze RNA-Seq data sets from 6,813 human tumors compared to those of adjacent normal tissue. Tumor samples representing 23 different forms of cancer were analyzed. HHV-6, EBV and CMV were found at significantly high levels in GI tract cancer tissue.

HHV-6 and EBV elevated in the GI tract of HIV+ patients

A group from Sapienza University in Rome has found a significantly elevated prevalence of HHV-6 and a higher viral load for EBV in the stomach and duodenum biopsies of patients with HIV compared to controls, suggesting that these viruses may contribute to the development of gastric cancer in immunocompromised patients.
