ABSTRACT
Antibody titers to all the Epstein-Barr virus (EBV)-related antigens were significant elevated (P less than 0.001) in patients with nasopharyngeal carcinoma (NPC) compared with those of controls. EBV, early antigen, and anti-diffuse titers of Chinese-American and black patients with NPC were higher than those of white patients with NPC. Epstein-Barr viral capsid antigen antibody titers were elevated in white patients with squamous cell carcinoma of the pharynx, regardless of subsite. These results raise doubts about the specificity of the association between EBV and NPC.

Lung cancer risk among occupational groups of women was reviewed. A previous suggestion of a sixfold risk of developing lung cancer among beauticians was not confirmed; however, an approximately twofold risk was found.

The epidemiology of nasopharyngeal cancer (NPC) has been compared with that of other pharyngeal cancers in Los Angeles County. Epstein-Barr virus (EBV) antibody titers were elevated in Caucasians with pharyngeal squamous cell carcinomas regardless of subsite. As expected, an excess of NPC cases was found among Chinese. The role of various etiologic factors in NPC including EBV, inhaled carcinogens, and salted fish was discussed.
