Epstein–Barr virus antibody level and gastric cancer risk in Korea: a nested case–control study

BACKGROUND: Few cohort studies have investigated Epstein-Barr virus (EBV) infection before the occurrence of gastric cancer. METHODS: Among 14 440 cohort participants, 100 incident gastric cancer cases were individually matched to two controls. Epstein-Barr virus antibodies IgG and IgA against viral capsid antigen (VCA), EBV nuclear antigen (EBNA) antibody IgG, and early antigen (EA) antibody IgG were measured using enzyme immunoassays (EIAs). RESULTS: The highest titres of VCA IgG (odds ratio (OR): 1.37, 95% confidence interval (CI): 0.62-3.06) or EBNA IgG (OR: 0.87, 95% CI: 0.51-1.46) were not associated with gastric cancer risk. CONCLUSION: Higher levels of VCA IgG or EBNA IgG were not associated with increased risk of gastric adenocarcinoma in Koreans.Akiba S, 2008, CANCER SCI, V99, P195, DOI 10.1111/j.1349-7006.2007.00674.xKoshiol J, 2007, BRIT J CANCER, V97, P1567, DOI 10.1038/sj.bjc.6604063Tedeschi R, 2007, AM J EPIDEMIOL, V165, P134, DOI 10.1093/aje/kwj332Gwack J, 2006, BRIT J CANCER, V95, P639, DOI 10.1038/sj.bjc.6603309Ouburg S, 2005, EUR J GASTROEN HEPAT, V17, P1213Chan D, 2005, J RES PRACT INF TECH, V37, P267HERRERAGOEPFERT R, 2005, WORLD J GASTROENTERO, V11, P6096CORREA P, 2004, GASTRIC CANCER, V7, P9Macsween KF, 2003, LANCET INFECT DIS, V3, P131Gartner BC, 2003, CLIN DIAGN LAB IMMUN, V10, P78, DOI 10.1128/CDLI.10.1.78-82.2003Burgess DE, 2002, BRIT J CANCER, V86, P702, DOI 10.1038/sj/bjc/6600107YOO KY, 2002, ASIAN PAC J CANCER P, V3, P85Chien YC, 2001, NEW ENGL J MED, V345, P1877Bruu AL, 2000, CLIN DIAGN LAB IMMUN, V7, P451Shinkura R, 2000, J MED VIROL, V60, P411Akre O, 1999, INT J CANCER, V82, P1Tokunaga M, 1998, CANCER EPIDEM BIOMAR, V7, P449*IARC, 1997, EPSTEINBARR VIR KAP, V8LEVINE PH, 1995, INT J CANCER, V60, P642LEHTINEN T, 1993, CANCER CAUSE CONTROL, V4, P187GESER A, 1982, INT J CANCER, V29, P397
