This study has been investigating two reports in recent times of the existence of human colorectal cancer (HCVs) in the Syrian population (16, 18, 31, 33 and 35) Epstein–Barr virus (EBVs). In this connection, the researchers reported on the co-presence of EBV and HPV in Syria in colorectal cancers. 17 (~17%) of 102 cancer samples have been positive for both EBV and HRVs, and are linked to high/mediate invasive carcinomas. This study showed that 17 of 102 cancer samples have been positive.

These statistics show that EBVs and high risk HPVs are co-present with human colorectal cancer in which the onset and/or development of these cancers can be cooperated. We therefore conclude that future studies are very important to validate the co-presence and collaborative role of these oncoviruses in human colorectal carcinogenesis.
