| Abstract: | Background: Head and neck cancer (HNC), including cancer of the oral cavity, pharynx, and larynx, is one of the leading cancers in the world. The known risk factors, including alcohol, betel quid, and cigarette, account for the majority of the HNC cases. However, the biological mechanisms regarding the carcinogenic effects of these agents in the development of HNC are not completely understood. Retinoic acid is involved in cell growth, differentiation, and apoptosis, which when dysregulated may lead to the development of cancer. Studies have shown that alcohol, betel quid, and cigarette can affect either the metabolism or the function of retinoic acid pathway. The current analysis evaluated the association between serum retinol and HNC risk and assessed whether this association can be modified by alcohol, betel quid, or cigarette. Methods: 93 incident cases of HNC and 79 sex- and age- frequency matched controls were recruited from the department of otolaryngology and department of stomatology. Information on the use of alcohol, betel quid, and cigarette was collected by in-person interviews. Serum retinol levels were measured using high performance liquid chromatography. Unconditional logistic regression was performed to estimate the odds ratio (OR) and 95% confidence interval (CI) of HNC risk associated with serum retinol levels. Additional analyses were performed stratified by alcohol, betel quid, and cigarette. Results: Compared to controls, HNC cases had a lower level of serum retinol (Median for HNC cases: 811 ug/l vs. median for controls: 901 ug/l, Wilcoxon rank-sum P = 0.04). For every 100 ug/l increase, the risk of HNC was reduced by 8% (OR = 0.92, 95% CI: 0.83-1.02). The OR was 0.5 (95% CI: 0.24-1.06) comparing the highest tertile of serum retinol level to the lowest tertile. A lower HNC risk associated with higher serum retinol levels was observed among never alcohol drinkers (For every 100 ug/l increment, OR = 0.80, 95% CI: 0.66-0.96) but not among regular alcohol drinkers (For every 100 ug/l increment, OR = 0.98, 95% CI: 0.86-1.13). Conclusion: Higher levels of serum retinol are associated with a reduced risk of HNC. Alcohol consumption obliterates the inverse association between serum retinol and HNC risk, possibly by disrupting the metabolism of retinoic acid pathway. |
