Abstract

Cancer of the oral cavity is a major and increasing public health problem. Oral cancer is the sixth most common cancer reported globally with an annual incidence of over 300,000 cases, of which 62% arise in developing countries. In India, because of cultural, ethnic, and geographic factors and the popularity of addictive habits, the frequency of oral cancer is high. Despite the various etiological and predisposing factors associated with oral pre-cancer and cancer, the role of co-carcinogenic effects of viruses like HSV has been documented. With this background and considering the high prevalence of oral cancer in India an attempt has been made to study the association of EBV with oral cancer using serological methods.
1. To study the IgG antibodies to Viral Capsid Antigen (VCA) of Epstein-Barr virus in oral pre-cancer and cancer by a laboratory standardized Indirect Immuno Fluorescent (IIF) test. 2. To compare and corelate the results of IIF test with a commercially available ELISA for VCA IgG antibodies to EBV. 3. To assess the severity of disease progression in oral pre-cancer and cancer using the serological profile.
In the present study, 84 subjects were assessed for serum IgG antibodies to VCA of EBV using the IIF technique and later the results were compared with an ELISA kit. Group I were controls, Group II to Group V were oral squamous cell carcinoma subjects according to the clinical staging. Group VI comprised of oral pre-cancer subjects. Age range was between 40-70 years, and the mean age was 50.31 +/- 8.23 years. All the 42 control sera were positive for IgG antibodies to VCA of EBV but with a significantly low geometric mean titre(GMT) of 8.561.The GMTs of oral squamous carcinoma and pre-cancer sera was positive but progressively increased when compared to control sera and were highly significant (P<0> As there was a significant increase in the GMTs in oral squamous cell carcinoma subjects and pre-cancer subjects, serology of EBV may be interpreted to be useful in assessing the severity of the disease and the techniques of IIF and ELISA may be used as first line screeners when large number of subjects need to be assessed.
