The common stereotype for a head and neck cancer patient is that of a poor, elderly man with a strong smoking or alcohol abuse history. However, smoking consumption continues to decline in many developed countries across the world and, in recent years, increasing data suggests a demographic shift for oral cavity cancers among patients without traditional risk factors. These “non-traditional” patients skew toward females, with a younger age of presentation.
In a recent population-level analysis, researchers sought to determine if a similar shift had occurred in two developed countries in the Asia-Pacific region, namely Australia and Singapore. Satgunaseelanab et al. utilized national cancer databases to identify oral cavity cancer patients from 1982 to 2012, stratifying analysis to patients <45 years of age versus those >45 years of age. Over 10,000 oral tongue cancer patients were identified, and the incidence of oral tongue cancer was shown to increase by over 3% per annum in females <45 years in both Australia and Singapore over the study period. In Australia, the incidence of oral tongue cancer remained stable in females >45 years and declined in males >45 years. The stable incidence in the female population >45 years was attributed to an increase in oral cavity cancer involving subsites other than the tongue. In a separate portion of the study involving a multi-institutional database review of tertiary care centers from Australia and Singapore, the proportion of oral tongue cancer among patients <45 doubled from 3.6% (1990–1994) to 8.2% (2010–2014).
These trends highlight the need to identify new etiologic factors for oral cavity cancer other than tobacco consumption/alcohol abuse. Various hypotheses have explored viral infections, genetic factors, and dental hardware — all of which have proved inconclusive thus far. Recognition of this demographic trend is essential for health care practitioners, as it supports applying a high index of suspicion for oral cavity cancer for patients with concerning clinical features, even in those patients that are younger and lack traditional risk factors.
