Semprini JT. Late-Stage Oral Cancer Detection After California and Illinois Restored Medicaid Dental Benefits. OTO Open 2024; 8:e111. [PMID: 38229972 PMCID: PMC10790188 DOI: 10.1002/oto2.111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Accepted: 12/31/2023] [Indexed: 01/18/2024] Open
Abstract
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.

FRONTIERS IN ORAL HEALTH 2023; 4:1056900. [PMID: 36794079 PMCID: PMC9922703 DOI: 10.3389/froh.2023.1056900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 01/03/2023] [Indexed: 01/31/2023] Open
Abstract
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.

Metaproteomic Analysis of an Oral Squamous Cell Carcinoma Dataset Suggests Diagnostic Potential of the Mycobiome. Int J Mol Sci 2023; 24:ijms24021050. [PMID: 36674563 PMCID: PMC9865486 DOI: 10.3390/ijms24021050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/16/2022] [Accepted: 12/23/2022] [Indexed: 01/07/2023] Open
Abstract
Oral squamous cell carcinoma (OSCC) is the most common head and neck malignancy, with an estimated 5-year survival rate of only 40-50%, largely due to late detection and diagnosis. Emerging evidence suggests that the human microbiome may be implicated in OSCC, with oral microbiome studies putatively identifying relevant bacterial species. As the impact of other microbial organisms, such as fungi and viruses, has largely been neglected, a bioinformatic approach utilizing the Trans-Proteomic Pipeline (TPP) and the R statistical programming language was implemented here to investigate not only bacteria, but also viruses and fungi in the context of a publicly available, OSCC, mass spectrometry (MS) dataset. Overall viral, bacterial, and fungal composition was inferred in control and OSCC patient tissue from protein data, with a range of proteins observed to be differentially enriched between healthy and OSCC conditions, of which the fungal protein profile presented as the best potential discriminator of OSCC within the analysed dataset. While the current project sheds new light on the fungal and viral spheres of the oral microbiome in cancer in silico, further research will be required to validate these findings in an experimental setting.

Abstract
PURPOSE The current study examined disparities in the associations between medically vulnerable populations and healthcare-related outcomes among population-based female cancer survivors and determined if these associations differed by length of cancer survivorship. METHODS One thousand eight hundred ninety-seven women with a cancer history from the National Health and Nutrition Examination Survey from 1999 to 2016 contributed data. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated with multivariable logistic regression models to measure the associations between the predictors (race/ethnicity, poverty status, education, comorbidity status, US nativity) and outcomes (perceived health, healthcare utilization and access outcomes), overall and by length of survivorship. RESULTS There was an average of 14.3 years (SD = 11.7; range = 2-84) since initial cancer diagnosis, with 25.1% being short-term and 74.9% being long-term survivors. Overall, racial/ethnic minority women were more likely to report poor/fair health status (OR, 2.68; 95% CI 1.73-4.15) and utilizing routine care other than a doctor's office/HMO (OR, 1.61; 95% CI 1.12-2.29) in comparison with NHW survivors. Length of survivorship significantly modified the association between race/ethnicity and odds of seeing a mental health provider in the last year (p-interaction = 0.003), with short-term minority survivors being significantly more likely (OR, 2.63; 95% CI 1.29-5.35) and long-term minority survivors being less likely (OR, 0.68; 95% CI 0.37-1.23). CONCLUSIONS Racial/ethnic disparities exist among female cancer survivors for perceived health status and certain healthcare utilization outcomes, with some differences observed by length of cancer survivorship. IMPLICATIONS FOR CANCER SURVIVORS This study can begin to inform cancer survivorship care for medically vulnerable women along the cancer continuum.

Cancer Prev Res (Phila) 2022; 15:733-746. [PMID: 36095092 DOI: 10.1158/1940-6207.capr-21-0567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Revised: 04/28/2022] [Accepted: 09/07/2022] [Indexed: 01/31/2023]
Abstract
Smokeless tobacco (SLT) use is a significant cause of lip and oral cavity cancers. Globally, oral cancer prevalence is strongly linked to the types of tobacco products used, their chemical composition, and their pattern of use. Except snus, all SLT products sold in different World Health Organization regions are strongly associated with oral cancer incidence. Shammah showed the highest association OR with 95% confidence intervals (CI; OR, 38.74; 95% CI, 19.50-76.96), followed by oral snuff (OR, 11.80; 95% CI, 8.45-16.49), gutkha (OR, 8.67; 95% CI, 3.59-20.93), tobacco with betel quid (OR, 7.74; 95% CI, 5.38-11.13), toombak (OR, 4.72; 95% CI, 2.88-7.73), and unspecified chewing tobacco (OR, 4.72; 95% CI, 3.13-7.11). Most SLT products containing high levels of carcinogenic tobacco-specific nitrosamines (TSNA) exhibit a high risk of oral cancer. There is an urgent need to frame and implement international policies for oral cancer prevention through legal control of the TSNA levels in all SLT product types. PREVENTION RELEVANCE Most smokeless tobacco products sold worldwide, mainly shammah, toombak, gutkha, betel quid with tobacco, and dry snuff, are associated with a high risk of oral cancer. A high concentration of tobacco-specific nitrosamines in smokeless tobacco products is the major causative factor for oral cancer development.

Semprini J. Oral cancer screening prevalence in low-income adults before and after the ACA. Oral Oncol 2022; 134:106055. [PMID: 36029746 PMCID: PMC11129732 DOI: 10.1016/j.oraloncology.2022.106055] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 07/15/2022] [Accepted: 07/29/2022] [Indexed: 11/16/2022]
Abstract
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.

Risk factors associated with head and neck cancer in former smokers: A Brazilian multicentric study. Cancer Epidemiol 2022; 78:102143. [PMID: 35378425 DOI: 10.1016/j.canep.2022.102143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 02/19/2022] [Accepted: 03/09/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Reduced tobacco consumption in the population has not been associated with reduced incidence rates of head and neck cancer in several countries. OBJECTIVE To explore the associations between HNC and sociodemographic characteristics and lifestyle of former smokers from three Brazilian cancer centers. METHODS A multicenter case-control study was conducted with 229 former smokers diagnosed with squamous cell carcinoma of the oral cavity, oropharynx, larynx, and 318 controls (former smokers without head and neck cancer). Bivariate and multiple logistic regression analyses were conducted to estimate odds ratios (ORs) with a 95% confidence interval (CI). RESULTS 11-20 years after smoking cessation showed significant impact on HNC reduction (OR 0.22, 95% CI, 0.12-0.39), which reached 82% (95% CI, 0.09-0.35) among 20 + former smokers when compared to individuals who had stopped smoking for up to 5 years. A history of high-intensity smoking (>40 pack-years) increased HNC risk by 2.09 times (95% CI 1.13-3.89) when compared to subjects who smoked up to 20 pack-years. Past alcohol consumption (OR 1.99, 95% CI, 1.06-3.82) was also associated with head and neck cancer risk in former smokers when compared to no alcohol consumption. There was a decreased head and neck cancer risk in former smokers who had high school level of education (OR 0.38, 95% CI, 0.16-0.91) compared to illiterate former smokers; and former smokers with moderate intake of vegetables (OR 0.49, 95% CI, 0.28-0.85) and fruits (OR 0.43, 95% CI, 0.25-0.73) compared to those with low intake. CONCLUSION Head and neck cancer risk in former smokers decreases after 11 years after smoking cessation, former smokers with past alcohol consumption showed an increased risk of HNC. High school level of education and moderate intake of vegetables and fruits reduced HNC risk among former smokers.

Abstract
Oral cancer is the most common form of head and neck squamous cell carcinoma (HNSCC) and most frequently presents as oral squamous cell carcinoma (OSCC), which is associated with an alarmingly high mortality rate. Internationally, a plethora of research to further our understanding of the molecular pathways related to oral cancer is performed. This research is of value for early diagnosis, prognosis, and the investigation of new drugs that can ameliorate the harmful effects of oral cancer and provide optimal patient outcomes with minimal long-term complications. Two pathways on which the progression of OSCC depends on are those of proliferation and apoptosis, which overlap at many junctions. Herein, we aim to review these pathways and factors related to OSCC progression. Publicly available search engines, PubMed and Google Scholar, were used with the following keywords to identify relevant literature: oral cancer, proliferation, proliferation factors, genes, mutations, and tumor suppressor. We anticipate that the use of information provided through this review will further progress translational cancer research work in the field of oral cancer.

Abstract
A significant number of cancer cases are afflicted by gastrointestinal cancers annually. Lifestyle and nutrition have a huge effect on gastrointestinal function, and unhealthy habits have become quite widespread in recent decades, culminating in the rapid growth of gastrointestinal cancers. The most prevalent cancers are lip and mouth cancer, esophageal cancer, gastric cancer, liver and bile duct cancer, pancreatic cancer, and colorectal cancer. Risk factors such as red meat consumption, alcohol consumption, tea, rice, viruses such as Helicobacter pylori and Ebstein Bar Virus (EBV), along with reduced physical activity, predispose the gastrointestinal tract to damage and cause cancer. According to the rapid increase of cancer incidence and late diagnosis of gastrointestinal malignancies, further epidemiological researches remain necessary in order to make appropriate population-based preventive policies. In this study, we reviewed clinical symptoms, risk factors, preventative measures, as well as incidence and mortality rates of gastrointestinal malignancies worldwide with focus on Iranian population.

Abstract
PURPOSE Cancer survivors are more likely to report having a poor health status when compared to the general population. Few studies have focused on the impact of cancer on health status and healthcare utilization/access outcomes among women from medically underserved populations. METHODS 25,741 women with and without a history of cancer from the National Health and Nutrition Examination Survey from 1999 to 2016 contributed data. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were estimated using multivariable logistic regression for associations between cancer status and perceived health and healthcare utilization/access outcomes stratified by race/ethnicity, poverty status, education, and comorbidities. RESULTS 1,897 (7.0%) women had a history of cancer with breast cancer as the most common (n = 671, 35.7%). While most survivors were non-Hispanic white (69.4%), 13.9% were Hispanic, 12.0% were non-Hispanic Black, and 4.6% were additional racial/ethnic groups. Survivors were 1.32 times more likely to be hospitalized within the last year (95% CI 1.11-1.58) and 1.32 times more likely to see a mental health provider within the last year (95% CI 1.05-1.66) compared to cancer-free women. Race/ethnicity was a significant effect modifier in the association between being a survivor and seeing a mental health provider, with Hispanic survivors having the highest odds (aOR 3.44; 95% CI 2.06-5.74; p-interaction < 0.00). CONCLUSION Our study identifies disparities in healthcare utilization among female cancer survivors, highlighting the importance of evaluating these associations among medically underserved populations. These findings can educate healthcare professionals working with these populations to inform gaps in survivorship care utilization/access.

Abstract
BACKGROUND The incidence rates of lip and oral cancer have continued to increase, and prognosis is associated with a country's socioeconomic status. The mortality-to-incidence ratio (MIR) is a reasonable indicator of disparities in cancer screening and treatment. In this study, we aimed to understand the association between economic status and cancer prognosis. METHODS Data were obtained from the Global Cancer Observatory (GLOBOCAN) and the World Health Organization (WHO). The MIRs were compared to evaluate the correlation with the human development index (HDI), the current health expenditure (CHE), and the ratio of CHE over gross domestic product (CHE/GDP) disparities via Spearman's rank correlation coefficient. RESULTS The results showed that Asia had the most cases and deaths. In addition, they showed a significant association (p < 0.001, p = 0.005, and p < 0.001, respectively) of the crude rate (CR) of incidence with the HDI, the CHE, and the CHE/GDP. However, their associations with mortality rate (p = 0.303, p = 0.997, and p = 0.101) were not significant. Regarding the correlation of the MIRs, the results revealed a significant association with the HDI, the CHE, and the CHE/GDP (p < 0.001, p < 0.001, and p < 0.001, respectively). CONCLUSION Countries with higher HDI, CHE per capita, and CHE/GDP tend to have lower MIRs, which indicates favorable clinical outcomes.

[PMID: 33879128 PMCID: PMC8056680 DOI: 10.1186/s12885-021-08198-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2020] [Accepted: 04/13/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Research suggests having an oral and pharyngeal cancer (OPC) examination for early diagnosis can increase survival rate. However, the OPC screening rate is low in certain populations. To improve OPC screening rate, this study identified factors that are associated with having an OPC examination. METHODS Participants with landlines and aged 25 years and older were recruited from six northern Florida counties. Bivariate and logistic regressions were used to predict the outcome of whether the participants had ever had an OPC examination as well as whether participants had ever heard of an OPC examination. RESULTS Of 2260 participants with a mean age of 55.9 ± 15.0 years, the majority of participants never smoked (53.4%), self-identified as Whites (70.6%), and had some college or 2-year degree education (30.3%). Smokers were significantly less likely to have ever heard of an OPC examination than those who never smoked. Significant interaction between smoking status and race, and smoking status and social support interaction were found. Whites who never smoked were more likely to have had an OPC examination than non-Whites who never smoked. Former and current smokers with greater social support were more likely to have had an OPC examination than those with lower social support. CONCLUSION The findings from this study inform the need to enhance the awareness of having an OPC examination among smokers and to reduce barriers for racial minority populations to receive an OPC examination. Future research is warranted to develop interventions to target certain populations to improve the rate of OPC examination.

Bioinformatics and immunohistochemistry analyses of expression levels and clinical significance of CXCL2 and TANs in an oral squamous cell carcinoma tumor microenvironment of Prophyromonas gingivalis infection. Oncol Lett 2021; 21:189. [PMID: 33574928 PMCID: PMC7816391 DOI: 10.3892/ol.2021.12450] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 12/07/2020] [Indexed: 01/31/2023] Open
Abstract
The present study aimed to detect the immunoexpression and clinical significance of Porphyromonas gingivalis (P. gingivalis) in the tumor microenvironment (TME) of oral squamous cell carcinoma (OSCC). The immunoexpression of P. gingivalis in OSCC tissues was detected via immunohistochemistry (IHC) after P. gingivalis was infected into the TME of OSCC. To identify the differentially expressed genes in the carcinogenesis and progression of OSCC with P. gingivalis infection, microarray datasets (GSE87539 and GSE138206) were downloaded from the Gene Expression Omnibus database. The immunoexpression levels of C-X-C motif chemokine ligand 2 (CXCL2) and tumor-associated neutrophils (TANs) were also evaluated via IHC, and the immunoexpression levels of all three clinical variables were analyzed using χ2 or Fisher's exact tests. The survival rates were calculated using the Kaplan-Meier method and the survival curves were compared using log-rank tests. Predominantly strong immunoexpression of P. gingivalis was identified in OSCC samples. CXCL2 was considered to be a differential gene in the two datasets. Immunoexpression of P. gingivalis was positively associated with CXCL2 and TANs expression. Furthermore, P. gingivalis was associated with survival status (P<0.001) and differentiation (P<0.001). CXCL2 was associated with age (P=0.038) and survival status (P=0.003), while TANs were associated with T stage (P=0.015) and clinical stage (P=0.002). These clinical variables were considered to be independent risk factors for the poor prognosis of patients with OSCC. Collectively, the results suggested that the immunoexpression of P. gingivalis may be positively associated with CXCL2 and TANs. In addition, the strong immunoexpression levels of P. gingivalis, CXCL2 and TANs may be associated with a poor prognosis in patients with OSCC.
