“…Additionally, EBV has also been reported with gastric cancer (Koriyama et al, 2001;Takada, 2000), breast (Labrecque et al, 1995;Bonnet et al, 1999;Fina et al, 2001) and lung cancer (Castro et al, 2001;Han et al, 2001; M.P. Wong et al, 1995). For colorectal cancer, although early studies have detected high rates of EBV infection in colorectal carcinoma tissue, using PCR, immunohistochemisrty and fluorescence in situ hybridization (Song et al, 2006;Liu et al, 2002Liu et al, , 2003, only one study reported significant difference in EBV detection rates between colorectal carcinoma tissue and adjacent normal mucosa (Song et al, 2006).…”
