This 30-year prospective cohort study of 162,000+ women challenges traditional oral cavity cancer (OCC) risk profiles by identifying sugar-sweetened beverages (SSBs) as an independent risk factor. The findings suggest dietary factors may contribute significantly to OCC risk beyond established factors like tobacco and alcohol, particularly in nonsmoking women.
Key Clinical Considerations
- Women consuming ≥1 SSB daily demonstrated 4.87x higher OCC risk compared to those consuming <1 SSB monthly, independent of smoking or alcohol status.
- Risk elevation was most pronounced (5x higher) among nonsmokers and light drinkers, translating to approximately 3 additional cases per 100,000 population.
- High-fructose corn syrup (HFCS), common in SSBs, may contribute to this association through multiple mechanisms: periodontitis development, glucose/insulin dysregulation, and oral dysbiosis.
- The study identified a potential shift in OCC demographics, with increasing incidence among nonsmoking women, particularly in white populations.
- Current US added sugar consumption (13% of total energy intake) significantly exceeds WHO recommendations (≤5%), highlighting a substantial population-level risk factor.
Clinical Practice Impact
- Patient Communication: Incorporate specific questioning about SSB consumption during oral cancer risk assessments, especially for female patients previously considered lower risk due to minimal tobacco/alcohol use.
- Practice Integration: Consider adding dietary counseling focused on SSB reduction as part of comprehensive oral cancer prevention strategies, targeting the 5% WHO added sugar guideline.
- Risk Management: Recognize that traditional OCC risk profiles may be evolving, with dietary factors potentially playing a more significant role than previously understood.
- Action Items: Document SSB consumption history in electronic health records alongside traditional risk factors; develop patient education materials specifically addressing the SSB-OCC risk association.
