BACKGROUND: there is, currently, much anecdotal and some epidemiological evidence for a rise in oral cancer rates amongst younger individuals, many of whom have had no exposure to traditional risk factors such as tobacco and heavy alcohol use, or at least not the exposure over decades usually associated with this disease. The probity of this assertion and the presence or absence of traditional risk factors needs further evidence. OBJECTIVES: this paper describes the demography and the exposure to potential risk factors amongst a cohort aged 45 years and younger, diagnosed with squamous cell carcinoma of the oral cavity between 1990 and 1997 from the South East of England. MATERIALS AND METHODS: eligible patients registered with a cancer registry were included in this retrospective study. Information was accessed from the database and by a postal questionnaire survey. The self-completed questionnaire contained items about exposure to the following risk factors: tobacco; alcohol; diet; frequency of dental visits and familial cancer. RESULTS AND CONCLUSIONS: this is the largest UK epidemiological study so far to be undertaken on young subjects diagnosed with oral cancer. One-hundred and sixteen cases were recruited representing a response rate of 59%. Slightly over 90% of this cohort were classified as white European. A large proportion of cases (40%) were from social classes I & II suggesting either a true social class difference in young cases versus older oral cancer cases or a possible bias in responders or survivors. Risk factors of tobacco use and excessive alcohol consumption were present in the majority (75%) of patients. Significant differences in the pattern of alcohol consumption were found in female subjects, who were less likely to consume over the recommended amounts of alcohol compared with male subjects. Daily regular fresh fruit and vegetable consumption during the ten year period before cancer diagnosis was recorded to be low. There was a distinct subgroup of cases, 26% of the group, that showed little, if any, exposure to any major risk factors. Copyright 2002 Elsevier Science Ltd.
