Abstract

The overall decline in incidence rate of nasopharyngeal carcinoma in Hong Kong during 1988-2002 was limited primarily to a decrease in keratinising carcinoma, which could be explained by the decline in cigarette smoking. Genetic and Epstein-Barr virus interactions may explain the relatively stable incidence rate of non-keratinising carcinoma.
