Association between perceived self-confidence and abilities to distinguish oral mucosal lesions amongst dental students. EUROPEAN JOURNAL OF DENTAL EDUCATION : OFFICIAL JOURNAL OF THE ASSOCIATION FOR DENTAL EDUCATION IN EUROPE 2022. [PMID: 35997548 DOI: 10.1111/eje.12850] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 02/07/2022] [Accepted: 06/13/2022] [Indexed: 06/15/2023]
Abstract
INTRODUCTION Dentists usually refer to difficulties in performing the diagnosis of oral mucosal lesions. This may be attributed to limited access to theoretical lectures and practical training on this subject along the graduation course. The primary aim of this cross-sectional study was to verify if there is an association between the perception of time dedicated to lectures/training and oral diagnosis abilities in oral medicine. The secondary aim was to evaluate the association between self--confidence to perform oral mucosal lesions diagnosis and performance in a diagnostic abilities test. MATERIALS AND METHODS The sample comprised 36 final-year dental students of a South-Brazilian dental school. The participants answered a questionnaire on their perception of time dedicated to lectures on oral medicine along the course (sufficient or insufficient) and their self-confidence to diagnose oral mucosal lesions or oral cancer (yes or not). The students were also submitted to a diagnostic abilities test based on 30 clinical photos of oral lesions, which should be classified as benign, potentially malignant or malignant. Moreover, the participants had to inform their clinical impression for each case. Finally, the participants informed their decision making for the case (refer the patient to a specialist or not). RESULTS Students with higher self-confidence showed a higher percentage of correct answers on classification of the nature of lesions (81.1% vs. 68.5%, p = .03, teste t de Student) and on their clinical impression (66.3% vs. 41.7%, p < .01, Student's t-test). The perception of time dedicated to theoretical lectures on oral medicine as sufficient did not influence the students' diagnostic abilities (p > .05, Student's t-test) CONCLUSION: It may be concluded that self-confidence to diagnose oral lesions is associated with dental students' diagnostic abilities.

Oral Squamous Cell Carcinoma in Young Patients Show Higher Rates of EGFR Amplification: Implications for Novel Personalized Therapy. Front Oncol 2021; 11:750852. [PMID: 34912708 PMCID: PMC8666981 DOI: 10.3389/fonc.2021.750852] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2021] [Accepted: 10/26/2021] [Indexed: 12/16/2022] Open
Abstract
There is an increasing worldwide incidence of patients under 50 years of age presenting with oral squamous cell carcinoma (OSCC). The molecular mechanisms driving disease in this emerging cohort remain unclear, limiting impactful treatment options for these patients. To identify common clinically actionable targets in this cohort, we used whole genome and transcriptomic sequencing of OSCC patient samples from 26 individuals under 50 years of age. These molecular profiles were compared with those of OSCC patients over 50 years of age (n=11) available from TCGA. We show for the first time that a molecular signature comprising of EGFR amplification and increased EGFR RNA abundance is specific to the young subset of OSCC patients. Furthermore, through functional assays using patient tumor-derived cell lines, we reveal that this EGFR amplification results in increased activity of the EGFR pathway. Using a panel of clinically relevant EGFR inhibitors we determine that an EGFR-amplified patient-derived cell line is responsive to EGFR inhibition, suggesting EGFR amplification represents a valid therapeutic target in this subset of OSCC patients. In particular, we demonstrate sensitivity to the second-generation EGFR tyrosine kinase inhibitor afatinib, which offers a new and promising therapeutic avenue versus current EGFR-targeting approaches. We propose that testing for EGFR amplification could easily be integrated into current diagnostic workflows and such measures could lead to more personalized treatment approaches and improved outcomes for this younger cohort of OSCC patients.

[PMID: 33658861 PMCID: PMC7917307 DOI: 10.2147/clep.s293929] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 01/28/2021] [Indexed: 11/23/2022] Open
Abstract
Background Changing patterns of alcohol and tobacco consumption and human papillomavirus (HPV) infection have affected the epidemiology of head and neck cancers. The aim of this study was to examine 20-year trends in the incidence and survival of head and neck cancers in Estonia by site, sex, morphology, and stage. Methods Data on all adult cases of invasive head and neck cancers diagnosed in Estonia in 1996–2016 were obtained from a population-based cancer registry. TNM stage was available for 2010–2016. Incidence trends were modeled with join-point regression, and five-year relative survival ratios (RSRs) were calculated. Results A total of 6,769 cases were included, 64% men. We observed declining incidence of lip and laryngeal cancer and substantial increases in the incidence of hypopharyngeal and oropharyngeal cancers. Over 60% of mouth and pharyngeal cancers were diagnosed at stage IV. Age-standardized 5-year RSR for mouth and pharyngeal cancer increased substantially over the study period, from 21% (95% CI 16%–25%) in 1996–2002 to 33% (29%–38%) in 2010–2016. The largest survival increases were seen for cancers of the oral cavity (reaching 44% in 2010–2016), tongue (41%), and larynx (63%), while modest changes were seen for the oropharynx (24%) and hypopharynx (17%). The latest 5-year RSR was 90% for thyroid cancers (99% for papillary carcinoma). Large female survival advantage was seen for most sites. Conclusion The observed trends suggest an emerging role of HPV infection in combination with traditional risk factors in the development of head and neck cancers in Estonia. Efforts targeting health behavior, HPV vaccination, and earlier diagnosis are crucial for reducing mortality from these cancers.

Abstract
OBJECTIVES This cross-sectional study aims to evaluate whether Continuing Education Activities (CEA) influence dentists' behaviour in relation to oral lesions. The secondary aim is to assess the association between dentists' perception of learning adequacy and self-efficacy for oral mucosal lesion management. METHODS A self-administered online questionnaire was conducted on dentists working at the public health system of Rio Grande do Sul State, Brazil. The questionnaire included questions pertaining to perception of adequacy for oral diagnosis classes upon graduation, participation in oral cancer CEA and self-efficacy in managing oral mucosal lesions. RESULTS 221 dentists from 91 municipalities answered the questionnaire. Most participants were female (71.5%) with a mean age of 38.3 years. Perception of learning as adequate during undergraduate coursework was associated with self-efficacy to diagnose, biopsy, and treat oral mucosal lesions (P < .05, Chi-squared test). However, 83.3% of dentists considered the time devoted to these topics prior to graduation insufficient. The frequency of oral lesion detection was related to self-efficacy to treat oral lesions and detecting oral cancer (P < .05, Chi-squared test). Among dentists who detected oral lesions frequently, 88.9% had attended CEA, whereas 11.1% of them had never attended these activities. CONCLUSIONS CEA may improve awareness and efficacy of primary healthcare professional's detection of oral cancer.

Oral cancer awareness campaign in Northern Germany: first positive trends in incidence and tumour stages. J Cancer Res Clin Oncol 2020; 146:2489-2496. [PMID: 32617703 PMCID: PMC7467915 DOI: 10.1007/s00432-020-03305-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Accepted: 06/26/2020] [Indexed: 11/12/2022]
Abstract
PURPOSE Oral cancer is a still underestimated public health problem. In Germany, until 2007, there was no systematic approach available for the purpose of raising the awareness of the public. From 2007 to 2011, a concept was developed for such an approach, and the campaign was launched in Northern Germany in 2012, and concluded in 2014. This report aims at presenting incidence trends of oral cancer, stratified according to sex, age, and tumour stages, before the introduction of this campaign and upon completion thereof. METHODS The data kept by the Schleswig-Holstein Cancer Registry on incidence rates (ICD-10, C00-C14) focused on oral cancer (C00-C06) and stratified by sex, age-groups and tumour stages, from 2000 to 2006 and from 2007 to 2014. RESULTS From 2000 to 2014, a total of 6760 cases of oral and pharyngeal cancer (C00-C14) were registered. When data on oral cancer was taken into account, stage I cancers of women in particular, increased over time. Regarding the stages, stage IV was the most frequent and stage I the second most frequent stage for both men and women. Over time, a small shift towards detection of tumours at earlier stages was observed. CONCLUSION A slight trend towards a temporary increase in incidence rates, especially among women, was observed. From an epidemiological point of view, this might indicate the initial success of this campaign. The slight trend in favour of stage I tumours could be seen as an initial minor success in terms of the early detection of oral cancer.

Abstract
OBJECTIVE To quantify the relationship between Citrus intake and risk of cancer of the oral cavity and pharynx. DESIGN Systematic review and meta-analysis. DATA SOURCES Ovid MEDLINE, EMBASE, and Web of Science were searched until September 2017. Search terms included Citrus, Citrus aurantifolia, Citrus sinensis, Citrus paradisi, Citrus fruits, Citrus fruits extract, Citrus oil, fruits, oral cancer, mouth cancer, mouth neoplasm. STUDY SELECTION The selection of studies and the systematic review were carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A pre-defined inclusion checklist resulted in the inclusion of articles which were (i) published in peer-reviewed scientific journals; (ii) English language; (iii) and included a measure of Citrus fruit intake and risk of oral and pharyngeal cancer. Studies were excluded if (i) preparations derived from other fruits were used, (ii) Citrus intake was combined with intake of other fruits; (iii) in vitro or animal models were used. We also excluded reviews, systematic reviews, meta-analyses, letters, personal opinions, conference abstracts and book chapters. DATA EXTRACTION Three reviewers independently performed the extraction of data from studies included. RESULTS Seventeen studies met our inclusion criteria and were included in the final review. Pooled analyses showed that those with the highest Citrus fruit intake compared to the lowest intake had a 50% reduction in risk of oral cavity and pharyngeal cancer (OR 0.50; 95% CI 0.43-0.59). CONCLUSION The studies included in this review and meta-analysis showed an inverse association between Citrus fruit intake and oral cancer.

Abstract
Background Oral cancer is a significant public health problem world-wide and exerts high economic, social, psychological, and physical burdens on patients, their families, and on their primary care providers. We set out to describe the changing trends in incidence and survival rates of oral cancer in Ireland between 1994 and 2009. Methods National data on incident oral cancers [ICD 10 codes C01-C06] were obtained from the National Cancer Registry Ireland from 1994 to 2009. We estimated annual percentage change (APC) in oral cancer incidence during 1994–2009 using joinpoint regression software (version 4.2.0.2). The lifetime risk of oral cancer to age 79 was estimated using Irish incidence and population data from 2007 to 2009. Survival rates were also examined using Kaplan-Meier curves and Cox proportional hazard models to explore the influence of several demographic/lifestyle covariates with follow-up to end 2012. Results Data were obtained on 2,147 oral cancer incident cases. Men accounted for two-thirds of oral cancer cases (n = 1,430). Annual rates in men decreased significantly during 1994–2001 (APC = -4.8 %, 95 % CI: −8.7 to −0.7) and then increased moderately (APC = 2.3 %, 95 % CI: −0.9 to 5.6). In contrast, annual incidence increased significantly in women throughout the study period (APC = 3.2 %, 95 % CI: 1.9 to 4.6). There was an elevated risk of death among oral cancer patients who were: older than 60 years of age; smokers; unemployed or retired; those living in the most deprived areas; and those whose tumour was sited in the base of the tongue. Being married and diagnosed in more recent years were associated with reduced risk of death. Conclusion Oral cancer increased significantly in both sexes between 1999 and 2009 in Ireland. Our analyses demonstrate the influence of measured factors such as smoking, time of diagnosis and age on observed trends. Unmeasured factors such as alcohol use, HPV and dietary factors may also be contributing to increased trends. Several of these are modifiable risk factors which are crucial for informing public health policies, and thus more research is needed.

Abstract
Recent studies show an increased incidence of head and neck cancers worldwide. The present study evaluated the trend in the incidence of head and neck cancers in England during 2002-2011. Data were extracted from the database of Office for National Statistics. The study population was categorised according to age, residential area, gender and cancer sub-types. Overall trend in incidence of head and neck cancer and some subtypes were examined using Poisson regression models. In total, 71,457 head and neck cancers were registered in England between 2002 and 2011 and 68% of patients were males. Statistically significant increases in incidence of 27.0 and 32.4% were documented in males and females, respectively (p<0.001) with the largest increase in the 60+ age category. Potentially HPV-associated cancers, oral cavity cancers and laryngeal cancers increased by 47.1, 24.1 and 1.7% in males and 37.5, 25.5 and 7.7% in females, respectively (p<0.001). Regional differences were also noted with the highest incidence (18.0 and 17.0 per 100,000, respectively) in the North East and North West of England. Our results for England showed an increase in the incidence of both oral cavity and oropharyngeal cancer in both genders, whilst laryngeal cancer incidence remained stable.

Abstract
OBJECTIVES Oral and pharyngeal cancer is still a serious health problem with an annual incidence of about 13,000 in Germany. This study aimed at describing trends of incidence and mortality in Germany by age, sex, and sub-site as a baseline for an oral cancer prevention campaign. METHODS Using data from the National Association of Population-based Cancer Registries, incidence rates for oral and pharyngeal cancer (ICD-10, C00-C14) from 2003 to 2011 and mortality rates from 1990 to 2012 were analysed by age, sex, and sub-site (C00-C06, C07-C08, C09-C14). Trends were described by annual percentage changes. RESULTS Men are 2.5-times more likely than women to be diagnosed and 3-times more likely to die from this tumour. Incidence and mortality in women increased slightly during the last decade, while incidence and mortality in men remained stable at a high level. While a decline was observed for younger age groups, an increase was seen in the elderly. For some sub-sites a deviation from this overall pattern was observed. CONCLUSIONS The decrease in this tumour in younger age groups is pleasing and may be attributed to public efforts in non-smoker protection in recent years. Further efforts are needed to counteract the increasing burden of disease in older age groups and in men.

Abstract
For patients without symptoms and at risk, there is no established early detection program to discover carcinomas of the upper aerodigestive tract in the sense of secondary prevention. Such type of prevention seems even more desirable because the chances for a cure and the quality of life are strongly dependent on the stage of the tumor and the time of the initial diagnosis. Six hundred and eight patients without symptoms but at least one of the self-reported risk factors "smoking", "alcohol consumption" or "reflux" were examined with an endoscope or an optical microscope for pathological findings in the upper aerodigestive tract once a year. In addition, the incidence of malignancies of the upper aerodigestive tract between 2001 and 2010 was determined through the Cancer Registry of Schleswig-Holstein. Tissue samples were taken from 18 of the 608 patients. Eleven patients (1.8%) had a squamous cell carcinoma. Another patient suffered from non-Hodgkin's lymphoma and one from larynx tuberculosis. The ratio of detected malignancies in the oral cavity and the oropharynx on the one hand and the hypopharynx and larynx, which can only be examined by endoscopes, on the other hand were in our cohorts and in our survey according to the cancer registry was 5/6. The above-described methods allow examining risk patients easily and safely. According to current publications, the ratio of the found malignancies exceeds the expected ratio significantly, which presumably was caused by the examination targeting patients at risk. Due to the expanded examination area using optical instruments more than doubles the rate of discoverable malignancies compared to the limitations posed by the examination of directly visible areas of the oral cavity of the oropharynx.
