[Detection of Epstein-Barr virus DNA in salivary gland tumors].
To evaluate the relations between salivary gland tumors and Epstein-Barr virus (EBV), the levels of EBV-related antibodies were examined, and detection of EBV nuclear antigen (EBNA) and EBVDNA in tumor tissue was attempted by the anti-complement immunofluorescence technique and polymerase chain reaction, respectively. The mean VCA-IgG antibody level was increased to 925 (80-2560) in Warthin's tumor, 496 (40-2560) in mucoepidermoid tumor, and 206 (40-640) in pleomorphic adenoma. The positive rate of EA-IgG was high in Warthin's and mucoepidermoid tumors. VCA-IgA antibody was positive in 2 of the 7 cases of Warthin's tumor. EA-IgA antibody was negative in all cases. EBVDNA was detected in 7 of the 7 cases of Warthin's tumor, 3 of the 5 cases of mucoepidermoid tumor, and 2 of the 26 cases of pleomorphic adenoma. A relationship between Warthin's tumor and EBV was suggested by the 100% detection rate of the viral DNA.
