Disparities in Oral Cancer Screening Among Dental Professionals: NHANES 2011-2016

Oral and oropharyngeal cancer screening and tobacco cessation discussions, NHANES 2011-2018

OBJECTIVE

Oral cavity and oropharyngeal cancer (OOPC) is a devastating disease often caught in late stages. People who use tobacco are at higher risk of OOPC. Tobacco cessation discussions and OOPC screenings are important factors in decreasing the risk of OOPC or its late stage diagnosis. As research on sex differences has been increasing-from research on biomedical to psychological and sociological determinants-there is a potential difference, by sex, as to whom is more likely to have a tobacco cessation discussion and OOPC screening. The objective of this study is to determine if there is an association of sex with tobacco cessation discussions and OOPC screenings conducted by dental healthcare professionals among participants who currently use tobacco.

METHOD

Data from 8 years of the National Health and Nutrition Examination Survey (2011-2018) were merged. Data from participants, ages 30 years and above, who self-reported current use of tobacco, a dental visit within the previous year and responsed to questions about oral cancer screening were analysed for frequency determination and logistic regression analysis. Having the combination of neither OOPC screening nor discussion about the benefits of not using tobacco was the outcome in the analysis.

RESULTS

There were 22.1% who had an OOPC screening by a dental professional within the previous year. Of the 41% who reported having had a conversation with a dental professional within the previous year about the benefits of tobacco cessation, 9.8% reported having both the conversation and OOPC screening. Males were less likely than females to have the combination of neither OOPC screening nor advice about tobacco cessation than females (adjusted odds ratio: 0.74; 95%CI: 0.57, 0.96).

CONCLUSION

There is an increased need for OOPC screening and the discussion of tobacco use by dental professionals among their patients who use tobacco, particularly for female patients.

Exploring health advice by dental professionals in USA: A secondary data analysis of NHANES (2015-2018)

OBJECTIVES

To examine socioeconomic and ethnic variations in the provision of health advice by dental professionals.

METHODS

Data were from the National Health and Examination Survey (NHANES) (2015-2018). Socioeconomic position (Poverty-income ratio and education) and ethnicity were the main exposures. The outcome variable of interest was whether participants received health advice regarding the "benefits of quitting cigarettes," "benefits of monitoring blood sugar levels," and "importance of oral cancer screening". Logistic regression analysis was used to examine the relationship between socioeconomic factors/ethnicity, and health advice after adjusting for covariates.

RESULTS

The analysis included a total of 5524 people aged eighteen and above who had complete data. Black and Hispanic individuals had higher odds of receiving advice on smoking (OR = 1.49, 95% CI: 1.04-2.12 and OR = 1.48, 95% CI: 1.05-2.07, respectively) and glucose monitoring (OR = 3.00, 95% CI: 2.03-4.43 and OR = 3.14, 95% CI: 2.04-4.82, respectively), but no significant difference for cancer screening advice.Higher poverty-income ratios (PIR) were associated with lower odds of receiving smoking advice (OR = 0.91, 95% CI: 0.84-0.98), but no significant associations were observed for glucose monitoring or cancer screening advice. The study's findings reveal a social gradient in the provision of cancer advice, with individuals having higher education levels, particularly university education (OR = 1.69, 95% CI: 1.24-2.31), showing significantly higher odds of receiving cancer screening advice CONCLUSION: The study highlights significant variations in health advice provision in dental settings, with education level, ethnicity, and smoking status playing prominent roles, emphasizing the need for targeted interventions to promote equity and cultural competence in delivering health advice in dental settings.

PRACTICE IMPLICATION

The results emphasize the importance of strong policies and ongoing education for dental professionals to ensure optimal treatment and prevention.

Late-Stage Oral Cancer Detection After California and Illinois Restored Medicaid Dental Benefits

Objective

Previous research found an association between California's Medicaid dental coverage and oral cancer detection. However, this relationship has yet to be explored in other states or by subgroup populations.

Study Design

In addition to controlling for sociodemographic and tumor characteristics, this study implemented a traditional difference-in-differences design to compare distant-stage diagnosis trends in states restoring Medicaid dental benefits (California [CA] and Illinois [IL]) with trends in states with constant Medicaid dental benefits.

Setting

This retrospective, observational study analyzed oral cavity and pharynx cancer case data from The Surveillance, Epidemiology, and End Results program (2004-2017).

Methods

The outcome was a binary variable indicating whether a patient was diagnosed at a distant stage. Subgroup analyses were conducted by state, race/ethnic group, sex, age, and county-level household income.

Results

The sample included 109,997 adults diagnosed with cancer of the oral cavity and pharynx. Restoring Medicaid dental benefits was associated with a statistically significant 2.7%-point decline in the probability of a distant-stage oral cancer diagnosis. This estimate represented a 14% relative change from baseline rates. Results were consistent for CA and IL and by county-level median income. Estimates were significantly larger for adults under age 65, males, and adults identifying as Hispanic; non-Hispanic Black; American Indian; or Asian American or Pacific Islander.

Conclusion

Restoring Medicaid dental coverage improved early detection in both CA and IL, with the greatest reductions in distant-stage diagnoses occurring in younger adults, males, and minoritized racial/ethnic groups. Future research should investigate whether earlier detection reduces oral cancer mortality disparities.

Head and neck exam practices of dental professionals

OBJECTIVE

Periodic examination of the head and neck includes screening for oral cancer, which is largely performed in dental offices by vigilant oral healthcare providers. The aim of this study was to assess practice patterns among Virginia dentists in performing head and neck exams and the referral rates of biopsies after completion of head and neck exams. We hypothesized that not all dentists perform head and neck exams and there is a difference between dentists who refer patients for a biopsy and those that perform biopsies.

METHODS

General dentists and dental specialists who are members of the Virginia Dental Association were invited to participate in a cross-sectional survey study through REDCap to self-report their head and neck exam protocols.

RESULTS

A total of 224 providers completed the survey. The majority of respondents were general dentists with more than 20 years in practice, who practice in a private setting, and see more than 10 patients in a day. All respondents stated they perform intraoral examinations, but 10 respondents stated they do not perform extraoral examinations. Nearly a third of respondents reported doing their own biopsies.

CONCLUSIONS

Although only 8.5% of oral healthcare providers in Virginia responded to our survey, respondents are following the 2017 ADA good practice statement by providing their patients with head and neck exams to screen for oral cancer. Additional education pertaining to extraoral anatomy, malignant transformation of oral potentially malignant disorders, and pathology procedures may be helpful to clinicians.

Oral cancer screening knowledge and practices among dental professionals at the University of Toronto

INTRODUCTION

Opportunistic oral cancer screening during visits to the dentist is a non-invasive and accessible option for detection of pre-malignant lesions and early-stage malignancies. The objective of this study was to investigate the knowledge, practices, and attitudes towards oral cancer screening among dentists.

METHODS

A 42-item survey was sent to 650 dental professionals affiliated with the University of Toronto. Data regarding training/practice characteristics, knowledge of oral cavity cancer, current screening practices, attitudes towards screening, and remuneration were collected.

RESULTS

Ninety-one dentists responded. Most obtained their dental degree from Canada (71.4%) and were practicing in large urban centers (87.9%). Most dentists correctly identified the oral tongue (87.8%) and floor of mouth (80%) as the two of most common sites of oral cavity cancer but only 56% correctly identified the most common presentation. 91% performed intra/extra oral examinations at every patient visit. Only 9.9% of dentists discussed the risk factors of oral cancer and 33% were not familiar with resources for smoking cessation and alcohol abuse. International medical graduates were more likely to discuss risk factor management than Canadian medical graduates (p < 0.01). Over 80% of dentists referred to a specialist when a suspected lesion was found. The greatest barrier for oral cancer screening was lack of time. Almost all dentists (98.8%) reported that their screening practices do not differ depending on the patient's insurance status and 63.8% reported compensation would not influence their decision to perform oral examinations.

CONCLUSION

Most dentists have a good knowledge of the presentation and risk factors associated with oral cavity cancer. Most dentists perform screening with every patient, with no influence from compensation and insurance status. Dentists are therefore an excellent first contact for oral cavity cancer screening for the general public and for high-risk populations.

Knowledge and awareness of oral cancer: A cross-sectional survey in Trieste, Italy

The aim of the study was to verify the knowledge on oral cancer and to assess possible differences in awareness and information basing on different demographic and subject-related factors. An anonymous survey was provided to 750 random subjects using online-based questionnaires. Statistical analysis was performed in order to evaluate the influence of demographic variables (gender, age, education) on knowledge of oral cancer and its risk factors. 68.4% of individuals knew about the existence of oral cancer, mostly from media and family/friends. Awareness was significantly influenced by gender and higher education, but not by age. Most participants recognized smoking as a risk factor, but alcohol abuse and sunlight exposure are less known, especially among less educated subjects. On the contrary, our study shows a diffusion of false information: more than 30% of the participants indicated the possible role of amalgam fillings in oral cancer onset, independently of gender, age or education. The results of our study suggest the need for oral cancer awareness campaigns, where school and healthcare professionals should be actively involved in promoting, organizing and finding methods to monitor the medium and long-term efficacy with proper methodological quality.

Oral cancer screening prevalence in low-income adults before and after the ACA

BACKGROUND

Detecting oral cancer early is associated with higher probability of survival, reduced treatment costs, and improved quality of life. Unfortunately, <30% of oral cancers are detected early. Recent health insurance expansions from the Affordable Care Act (ACA) could improve outcomes by increasing access to screening. However, due to the differences in screening practices by physicians and dentists, the impact of expanded access to insurance on oral cancer screenings remains unknown.

METHODS

Self-reported oral cancer screening data were obtained from The National Health and Nutrition Examination Survey (NHANES) for years 2011-2017. NHANES questionnaires ask respondents if they have received an oral cancer screen from a physician or dentist in the past year. Along with adjusting for demographic characteristics, this study accounts for unobserved heterogeneity by comparing "Differences-in-Differences" estimates of low-income adults (<200 % FPL) with high-income adults, before and after the ACA (2014), for adults most exposed (<age 65) to insurance expansion.

RESULTS

Before and after the ACA, low-income adults had the lowest prevalence of oral cancer screenings. However, relative to high-income adults, the ACA was associated with a 5-6%-point increase in oral cancer screenings for low-income adults under age 65, but only for screenings performed by dentists.

CONCLUSIONS

Overall, oral cancer screening rates have been declining across the population, but the ACA may have slowed the decline in low-income adults. Understanding why oral cancer screenings are declining could inform cancer control policies. Research evaluating the impact of access to oral cancer screenings remains warranted.

A feasibility and acceptability study of using an intra-oral camera and an asynchronous tele-mentoring protocol to detect and identify oral lesions

Background:

To examine the feasibility and acceptability of integrating a tele-mentoring component into the identification of oral lesions at the dental clinics of a Federally Qualified Health Center network.

Design and Methods:

General Practice Residency faculty and residents completed research ethics courses and trained dentists to use intra-oral cameras at chairside to photograph oral lesions of patients at routine dental visits. These images were then uploaded into the patient electronic health records (EHRs) with attendant descriptions and an oral surgeon was notified, who reviewed the charts, placed his observations in the EHR, and communicated his findings via secure e-mail to the involved residents, who in turn contacted their patients regarding follow-up actions. Feasibility was assessed via checklists completed by provider participants and semi-structured interviews. Acceptability was assessed via brief exit interviews completed by patient participants.

Results:

All 12 of the dentist participants reported that they had successfully provided the tele-mentoring intervention, and that the process (from EHR data entry to interaction with the oral surgeon over findings to patient referral) was clear and straightforward. Of 39 patient participants, most strongly agreed or agreed that the use of an intra-oral camera by their dentists helped them to better understand oral cancer screening (94.9%) and that dentists answered their questions about oral cancer and were able to provide them with resources (94.8%).

Conclusions:

Findings support further implementation research into adapting tele-mentoring using intra-oral cameras for training dental residents to detect and identify oral lesions and educating patients about oral cancer across settings.

Patient Characteristics in Oral Cancer Staging

Background

Oral cancer is a largely preventable malignancy with many modifiable risk factors, such as tobacco use and proper oral hygiene. Early detection of oral cancer is an important goal for oral healthcare providers, as survival rates for oral cancers diagnosed at an advanced stage are less than half the rates for cancers diagnosed in early stages. As many patients are asymptomatic in early stages, it is crucial for oral healthcare providers to have a high index of suspicion while treating patients at risk for late diagnosis.

Objectives

To identify characteristics associated with early vs. late stage diagnosis of oral cancer.

Methods

We performed a retrospective chart review using the TriNetX database. We identified two cohorts of interest: patients with an initial diagnosis of stage 1 oral cancer, and patients with an initial diagnosis of stage 3 or 4 oral cancer. Statistical comparison of cohort characteristics was completed through the TriNetX statistical software platform.

Results

We identified 386 patients diagnosed at stage 1 and 869 patients diagnosed at stage 3 or 4. We identified several characteristics not previously reported in the literature. Race, BMI between 20 and 29, malnurition, anemia were all associated with late stage diagnosis. Certain medications were also associated with late stage diagnosis, such as heparin derivatives and diclofenac. Our findings also reinforced prior research for characteristics such as nicotine use and ethnicity.

Conclusion

Our findings offer new characteristics that may aid oral healthcare providers in detecting oral cancer at an early stage. Increasing provider awareness of factors that they may not have considered previously could increase the rates of early stage cancer detection, improving overall patient mortality and curative outcomes.

Effectiveness of Interventions to Improve Oral Cancer Knowledge: a Systematic Review

Oral cancer is prone to late-stage diagnosis, and subsequent low five-year survival rates. A small number of interventions or campaigns designed to enhance knowledge of risk factors and symptoms associated with oral cancer have been attempted in the UK, US, and some other countries. The purpose of this systematic review is to assess the effectiveness of interventions designed to improve oral cancer knowledge. We searched five databases to identify randomized controlled trials (RCTs) and non-randomized/quasi-experimental (NR/QE) studies targeting the general population or high-risk groups (tobacco users or alcohol consumers), aged ≥15 years, and reporting the outcomes of individual and/or community level interventions. Two co-authors independently identified relevant studies, extracted data, and assessed the risk of bias. Adhering to PRISMA guidelines, 27 (eight RCTs and 19 NR/QE studies) of the 551 studies identified from the five databases met the inclusion criteria. All RCTs and nine NR/QE studies used either printed materials, health education sessions, multimedia aids, or some combinations of these tools. The other ten NR/QE studies were community-based and used mass media campaigns to increase oral cancer awareness. Overall, the majority of studies significantly improved oral cancer knowledge; however, heterogeneity in study design and variation in measurement tools made it difficult to compare outcomes. Findings suggest that individual and/or community level interventions are generally effective in increasing knowledge of oral cancer risk factors, signs and symptoms, and/or its early diagnosis and prevention strategies among the general population or high-risk groups. However, the long-term benefits of these interventions are understudied.

Oral cancer patients achieve comparable survival at high safety-net burden hospitals

PURPOSE

To evaluate the impact of hospital safety-net burden and social demographics on the overall survival of patients with oral cavity squamous cell carcinoma.

MATERIALS AND METHODS

We identified 48,176 oral cancer patients diagnosed between the years 2004 to 2015 from the National Cancer Database and categorized treatment facilities as no, low, or high safety-net burden hospitals based on the percentage of uninsured or Medicaid patients treated. Using the Kaplan Meier method and multivariate analysis, we examined the effect of hospital safety-net burden, sociodemographic variables, and clinical factors on overall survival.

RESULTS

Of the 1269 treatment facilities assessed, the median percentage of uninsured/Medicaid patients treated was 0% at no, 11.6% at low, and 23.5% at high safety-net burden hospitals and median survival was 68.6, 74.8, and 55.0 months, respectively (p < 0.0001). High safety-net burden hospitals treated more non-white populations (15.4%), lower median household income (<$30,000) (23.2%), and advanced stage cancers (AJCC III/IV) (54.6%). Patients treated at low (aHR = 0.97; 95% CI = 0.91-1.04, p = 0.405) and high (aHR = 1.05; 95% CI = 0.98-1.13, p = 0.175) safety-net burden hospitals did not experience worse survival outcomes compared to patients treated at no safety-net burden hospitals.

CONCLUSION

High safety-net burden hospitals treated more oral cancer patients of lower socioeconomic status and advanced disease. Multivariate analysis showed high safety-net burden hospitals achieved comparable patient survival to lower burden hospitals.

Moving Beyond Detection: Charting a Path to Eliminate Health Care Disparities in Otolaryngology

The coronavirus pandemic has illuminated long-standing inequities in America's health care system and societal structure. While numerous studies have identified health care disparities within our specialty, few have progressed beyond detection. Otolaryngologists have the opportunity and the responsibility to act. Within this article, leaders from otolaryngology share their experience and perspective on health care disparities, including (1) a discussion of disparities in otolaryngology, (2) a summary of health care system design and incentives, (3) an overview of implicit bias, and (4) practical recommendations for providers to advance their awareness of health care disparities and the actions to mitigate them. While the path forward can be daunting, it should not be a deterrent. Throughout the course of this article, numerous resources are provided to support these efforts. To move ahead, our specialty needs to advance our level of understanding and develop, implement, and disseminate successful interventions toward the goal of eliminating health care disparities.

Prevalence and Factors Associated With Oral Cavity and Pharyngeal Cancer Screening in a Rural Population

Objective

(1) To quantify the prevalence of provider recommendation and receipt of oral cavity and pharyngeal cancer (OCPC) screening and (2) to examine the factors associated with OCPC screening recommendation and receipt among adults.

Study Design

Cross-sectional.

Setting

Rural counties in central Illinois.

Methods

This study among adults (N = 145) was conducted between January 1 and June 30, 2017. The outcomes of interest were provider recommendation and receipt of OCPC screening. Multivariable logistic regression models were used to examine the association between (1) sociodemographic, health care access and utilization, and OCPC risk factors and (2) provider recommendation and receipt of OCPC screening.

Results

The prevalence of provider recommendation and receipt of OCPC screening was 12.4% and 28.3%, respectively. Approximately 15% of current smokers, 13% of participants who consume alcohol, and 10% of participants with ≥5 lifetime sexual partners had received an OCPC screening recommendation. OCPC screening rates were 19% for current smokers, 30% for those who consume alcohol, and 32% for those with ≥5 lifetime sexual partners. In the adjusted analyses, respondents with ≥5 partners (adjusted odds ratio, 3.10 [95% CI, 1.25-7.66]) had a higher odds of receiving OCPC screening than those with <5. There were no significant associations between other OCPC risk factors and provider recommendation and receipt of OCPC screening.

Conclusion

OCPC screening recommendation and receipt were low; only number of lifetime sexual partners was associated with OCPC screening receipt. Our findings suggest that rural populations may be vulnerable to late-stage diagnosis of OCPC, and interventions to help improve screening rates are warranted.

Modeling oral cancer screening in the United States population

OBJECTIVES

To evaluate the impact of oral cancer screening if applied to the United States (US) population or various high-risk populations in the US.

METHODS

We modeled the effects of applying an oral cancer screening program to the US population assuming a similar mortality reduction as seen in the randomized Kerala trial. We combined data on the incidence of oral cancer in the Surveillance, End Results, and Epidemiology database, data on the relative risk in various high-risk groups from the Prostate, Lung, Cervical, and Ovarian screening trial, and the National Lung Screening Trial and data on the prevalence of cigarette use from the National Health Interview Survey.

RESULTS

When extrapolating to the US population we predict the number needed to screen to prevent one oral cancer death (NNS) = 9,845 in all individuals aged 35 + . Screening efficiency would increase if applied to higher-risk populations. If oral cancer screening were applied to male ≥ 60 pack-year current smokers or former smokers who have quit within 15 years aged 50-79 we predict a 4.6% reduction in oral cancer mortality with an NNS = 1,485.

CONCLUSIONS

Targeted screening of individuals at high risk for oral cancer has the potential to maximize the efficiency of screening and meaningfully impact oral cancer mortality. We suggest a future screening trial in high-risk individuals be considered to clarify the role of oral cancer screening in the US.

Cancer-Related Activity Limitations Among Head and Neck Cancer Survivors

OBJECTIVES/HYPOTHESIS

To characterize self-reported cancer-related activity limitations among a broad population of head and neck (HNC) survivors and identify sociodemographic factors associated with these limitations.

STUDY DESIGN

Cross-sectional analysis of data from the National Health Interview Survey.

METHODS

The study population included individuals who completed the National Health Interview Survey (NHIS) from 1997 to 2018 and self-reported a cancer diagnosis. Data regarding activity limitations, cancer history, mental health, and demographics were extracted from the NHIS. Poisson regression was used to evaluate associations between demographics and cancer-related limitations, and a descriptive analysis was performed to identify the most common types of cancer-related limitations experienced by HNC survivors.

RESULTS

Individuals with HNC were more than twice as likely to report having a disability caused by cancer when compared to individuals with other cancers (24% vs. 11%, P < .001). Cancer-related disability was highest among HNC survivors who were Black (adjusted prevalence ratio (aPR) = 1.57, 95% CI = 1.13-2.18), were aged 50 to 64 (aPR = 1.74, 95% CI = 1.1-2.74), had high school or lower education (aPR = 2.40, 95% CI = 1.07-5.37), and had Medicaid insurance (aPR = 2.58, 95% CI = 1.62-4.10). Among HNC patients who reported a cancer-related limitation, the most common limitations included difficulty working (78%), going out (51%), and socializing (42%).

CONCLUSIONS

Cancer-related activity limitations are more common among HNC survivors compared to survivors of other cancers, and disproportionately affect socioeconomically disadvantaged HNC survivors. Clinicians should be aware of the limitations experienced by HNC survivors to provide counseling and resources to help patients cope with these limitations.

Prognostic impact of socioeconomic status compared to overall stage for HPV-negative head and neck squamous cell carcinoma

OBJECTIVE

To estimate the relative prognostic ability of socioeconomic status (SES) compared to overall stage for HPV-negative head and neck squamous cell carcinoma (HNSCC) MATERIALS AND METHODS: Data were obtained from the Carolina Head and Neck Cancer Epidemiology Study (CHANCE). An empirical 4-category SES classification system was created. Cox proportional hazards models, survival gradients, Bayesian information criterion (BIC), and Harrell's C index were used to estimate the prognostic ability of SES compared to stage on overall survival (OS).

RESULTS

The sample consisted of 1229 patients with HPV-negative HNSCC. Patients with low SES had significantly increased risk of mortality at 5 years compared to patients with high SES (HR 3.11, 95% CI 2.07-4.67; p < 0.001), and the magnitude of effect was similar to overall stage (HR 3.01, 95% CI 2.35-3.86; p < 0.001 for stage IV versus I). Compared to overall stage, the SES classification system had a larger total survival gradient (35.8% vs. 29.1%), similar model fit (BIC statistic of 7412 and 7388, respectively), and similar model discriminatory ability (Harrell's C index of 0.61 and 0.64, respectively). The association between low SES and OS persisted after adjusting for age, sex, race, alcohol, smoking, overall stage, tumor site, and treatment in a multivariable model (HR 2.96, 95% CI 1.92-4.56; p < 0.001).

CONCLUSION

SES may have a similar prognostic ability to overall stage for patients with HPV-negative HNSCC. Future research is warranted to validate these findings and identify evidence-based interventions for addressing barriers to care for patients with HNSCC.

Association between periodontal disease and oral cancer screening among US adults: NHANES 2011-2014

OBJECTIVES

To examine oral cancer screening rates and associated factors among adults with periodontal disease (PD). We hypothesized that adults with severe PD will be less likely to report receipt of any type of oral cancer screening than adults with no PD.

MATERIALS AND METHODS

We used 2011-2014 National Health and Nutrition Examination Survey (NHANES) data on adults ≥30 years. PD status was classified as no PD, mild/moderate PD and severe PD. Survey-adjusted logistic regression analysis was used to examine the model adjusted risk ratio (RR) and 95% confidence intervals (CI) for the outcome of not receiving intraoral, extraoral or both types of oral cancer screenings among adults with PD. Control variables included age, sex, race/ethnicity, health insurance, education, income level, smoking status, alcohol use and last dental visit.

RESULTS

The analytic sample included 6962 adults weighted to the national population of adults who had a periodontal examination during 2011-2014. Overall, 31.5%, 26.8% and 20.9% of adults reported receipt of intraoral, extraoral and both types of oral cancer screening, respectively. Almost 40% of adults had some form of PD (7.6% severe and 32.4% mild/moderate PD). A higher proportion of 45-64-year-olds, males, non-Hispanic Blacks, those with less than high school education, with income level less than 200% federal poverty level, or those with no insurance had severe PD than no PD. In adjusted analyses, adults with severe PD were significantly more likely to report no receipt of intraoral (RR = 1.25, 95% CI = 1.12-1.40), extraoral (RR = 1.17, 95% CI = 1.07-1.27) or both types of oral cancer screenings (RR = 1.18, 95% CI = 1.10-1.27) than those with no PD.

CONCLUSIONS

Significantly low proportion of adult's age ≥30 years with severe PD reported receiving any type of oral cancer screening. The association between PD and risk of oral cancers points to the need to improve oral cancer screening rates among adults with PD.

Lifestyle risk factor related disparities in oral cancer examination in the U.S: a population-based cross-sectional study

Background

Oral cancers account for 3% of annual U.S. cancer diagnosis, 2 in 5 of which are diagnosed late when prognosis is poor. The purpose of this study was to report the population-level prevalence of oral cancer examination among adult smokers and alcohol drinkers and assess if these modifiable lifestyle factors are associated with receiving an oral cancer examination.

Methods

Adult participants ≥30 years (n = 9374) of the 2013–2016 cycles of the National Health and Nutrition Examination Survey were included. Oral cancer examination (yes/no), smoking (never, former, current) and alcohol use (abstainers, former, current) were self-reported. Survey-logistic regression estimated odds ratios (OR) and 95% confidence intervals (CIs) of ever and past year oral cancer examination adjusted for age, gender, race/ethnicity, education, income, and time since last dental visit.

Results

One third (33%) reported ever been examined for oral cancer, 66% of whom reported an examination in the past year. Adjusted OR (95% CI) of past year examination comparing current and former smokers to non-smokers were 0.51 (0.29, 0.88) and 0.74 (0.53, 1.04) respectively. Similarly, current and former alcohol drinkers relative to abstainers were less likely to report a past year oral cancer examination, OR (95% CI) = 0.84 (0.53, 1.30) and 0.50 (0.30, 0.83) respectively.

Conclusion

This study showed that smokers and alcohol users were less likely than abstainers to self-report a past year oral cancer examination. Access to affordable and targeted oral cancer examination within the dental care setting might ensure that these high-risk individuals get timely examinations and earlier diagnosis that might improve prognosis and survival.
