RESUMO
OBJECTIVES: To assess the use of tongue base palpation during cancer screening exams by Oral Healthcare Providers (OHPs) and explore attitudes about (1) the usefulness of oral cancer screening (OCS) in detecting early, asymptomatic lesions and (2) routine OCS of the general population. STUDY DESIGN: Survey study. SETTING: Private and hospital-based clinical practices of OHPs located in Massachusetts and Connecticut, United States. METHODS: An anonymous, online 9-item survey assessing beliefs and practice patterns about cancer screening exams was distributed to OHPs with practices in Massachusetts and Connecticut from August 2020 to June 2021. Data were analyzed using chi-square tests and Pearson correlations. Statistically significant levels were established at P < .050. RESULTS: One hundred seventy-one responses were analyzed (response rate 17 %). Tongue base palpation was performed as part of a routine cancer screening exam by 55 % of otolaryngologists, 34 % of dentists and 29 % of OMFS (P = .030). Providers who palpated the tongue base were also more likely to use palpation as an exam technique in the tonsils (r = 0.52 [95 % CI 0.40-0.62]; P < .001) among other intra-and extra-oral anatomical subsites. Almost all dentists (92 %) and OMFS (98 %) but only 58 % of otolaryngologists considered OCS useful for detection of early, asymptomatic malignant lesions in the oral cavity (P < .001). CONCLUSIONS: While tongue base palpation can detect oropharyngeal cancers in a pre-symptomatic stage, it is underutilized during routine cancer screening exams. Considering the rising incidence of oropharyngeal cancer, tongue base palpation should be established as a routine part of cancer screening by OHPs.
