Otolaryngol Head Neck Surg 2023; 168:1301-1311. [PMID: 36939409 DOI: 10.1002/ohn.214] [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: 08/04/2022] [Revised: 11/04/2022] [Accepted: 11/15/2022] [Indexed: 01/30/2023]
Abstract
OBJECTIVE Access to and use of physician services is limited for those experiencing homelessness. Homelessness may predispose patients to several Otolaryngology-Head and Neck Surgery (OHNS) health conditions and barriers to care may leave these unaddressed. The aim of this review was to synthesize the literature on OHNS health needs and community-based interventions for patients experiencing homelessness. DATA SOURCES English literature was searched in MEDLINE, EMBASE, and CINAHL. REVIEW METHODS Studies were included if they reported on OHNS-related conditions in patients experiencing homelessness and/or interventions related to providing OHNS care to this patient population. RESULTS Twelve hundred and one articles were screened, and 12 articles were included. Most studies reported on otologic conditions (n = 8) and head and neck-related conditions (n = 6). Nasal trauma, chronic rhinosinusitis, dysphonia, hearing loss, and cancerous/precancerous head and neck lesions were common OHNS conditions reported in this patient population. Identified barriers to care included lack of transportation, financial considerations, and lower health literacy. Three articles on community-based interventions were included. Most of these interventions were single visits to shelters, and ensuring adequate follow-up was identified as a challenge. CONCLUSION The current literature brings attention to certain OHNS diseases that are prevalent in this unique patient population and identifies unique barriers these patients experience when accessing care. Future studies should focus on further delineating the impact of OHNS diseases in patients experiencing homelessness and screening interventions that can be employed to mitigate the impact of diseases of the head and neck.

Abstract
BACKGROUND Chronic trauma of oral mucosa, resulting from repeated and persistent mechanical irritative action of an intraoral injury agent, has repeatedly been reported to be possibly implicated in the development of oral squamous cell carcinoma (OSCC). OBJECTIVES The present systematic review aimed to assess whether chronic mechanical trauma can be considered a risk factor for OSCC. DATA SOURCES PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), Scopus; EMBASE, Web of Science. STUDY ELIGIBILITY CRITERIA Cohort studies comparing OSCC incidence among subjects with/without chronic mechanical trauma or case-control or cross-sectional studies comparing chronic mechanical trauma among subjects with/without OSCC. RESULTS Only one prospective case-control study fulfilled the inclusion criteria, but the quality of the evidence provided is not enough to define trauma as a risk factor for OSCC. The main limitation is the presence of only one case-control study at high risk of bias. In the absence of strong evidence supporting the role of trauma in OSCC, a thorough discussion on trauma and carcinogenesis has been performed. CONCLUSIONS Available evidence does not support an active role for chronic trauma in oral carcinogenesis, neither as promoter nor as progressor factor. Prospective cohort studies able to better assess trauma in OSCC are needed.

Abstract
Squamous cell carcinoma (SCC) is the most common malignant tumor of the oral cavity. Since it spreads and metastasizes more quickly than any other form of glabrous skin carcinoma, SCC of the lips seems to be more harmful. This report highlights the case of a 67-year-old man who underwent a mandibulectomy for lip SCC, subsequently having complaints of severe trismus and jaw pain, dysarthria, and difficulty drinking water. The patient's symptoms and trismus improved significantly via a course of physiotherapy. Six weeks of physiotherapy with various interventions such as mouth opening and closing exercises along with tongue protrusion, lower limb and upper limb passive movements, breathing exercises, lower limb mobility exercises, speech therapy, static shoulder exercises, static gluteus exercises, static hamstring exercise, and static quadriceps exercises, shoulder shrugs, neck isometrics, and shoulder-scapular sets, including goldfish exercises and Rocabado exercises may be helpful for managing symptoms such as trismus and other associative problems such as maintaining circulation and avoiding compensatory posture, pulmonary complications, and secondary complications, which may be helpful for managing the patient after mandibulectomy.

Abstract
The purpose of this study was to investigate the relationship between oral and dental health in cancer patients and control group, which was conducted in Tabriz Shahid Gazi hospital. A researchers-made and validated questionnaire including oral and dental health criteria, was filled by the cancer patients (201 cases) and healthy controls (199 cases). Then, the results of the study were analyzed by SPSS software, and reported as Odds ratios (95 % confidence intervals) in tow groups. The results indicate that comparison of filled tooth, tooth extraction, dental caries, and gingival problems including bleeding, gum surgery and inflammation in cancer and controls were significantly meaningful. However, the comparison between the two groups was not significant in terms of the type of the tooth (natural or denture) and the number of daily toothbrushes, but they were considered as risk factors due to statistical results. Environmental factors, and especially oral hygiene, can play an important role in the incidence of different cancers. Among these, the type of oral microorganisms, and their overgrowth and released antigens should be studied further in the emergence of different kinds of cancer in humans.

Abstract
OBJECTIVES Genomic instability in cancers is often associated with poor disease outcomes. In Head and Neck Squamous Cell Carcinoma (HNSCC), saliva being the contact fluid contains cancers cells shed from the primary tumour. This study detected genomic instability from cancer cells shed in saliva and correlated the same with clinical implications. DESIGN Genomic instability in HNSCC patients (n = 81) was analysed and compared with control subjects (n = 30). Alu sequences were amplified from the DNA of the cells shed in saliva and from the blood (Germline DNA) using Alu-PCR. Band variations between amplified products of salivary cells' DNA and germline DNA were compared. 'Instability Score' was calculated by counting the band variation(s). The 'Instability Score' was further used as a measure of genomic instability. RESULTS Higher instability was detected in patients as compared to the controls (p < 0.0001). After treatment, there was a significant decrease (p < 0.0001) in the Instability score and patients with higher instability scores responded better to radiotherapy. The patient group consuming both tobacco and alcohol had a higher instability score in comparison to the tobacco group (p = 0.0056). Also, Instability scores are inversely correlated with nodal metastasis (p = 0.0075). A high Instability score before treatment resulted in a better prognosis in HNSCC patients (HR: 1.8, 95%CI: 1.024-3.164, p = 0.0306). CONCLUSION Our data suggest that genomic instability estimated from the tumour cells shed in the saliva of HNSCC patients by amplifying Alu sequence (Alu-PCR) is associated with radiotherapy response.

Abstract
OBJECTIVE Results of epidemiological studies evaluating the association between toothbrushing and gastric and upper aerodigestive tract (UADT) cancer risk showed inconsistent results. The purpose of this study was to evaluate the association between toothbrushing and gastric and UADT cancer risk and quantify the dose-response association between them. METHODS We searched the PubMed, EMBASE and Cochrane Library databases to identify relevant studies on toothbrushing and gastric and UADT cancer risk. Statistical analyses were performed using STATA 12.0 software. RESULTS A total of 30 studies of involving 1 194 017 participants met eligibility criteria and were included in the meta-analysis. Meta-analysis using a random-effect model showed that the high frequency of toothbrushing was associated with significantly reduced risk of gastric and UADT cancers (OR: 0.55, 95% CI 0.46-0.64, P < .05). Our dose-response analysis presented that every increased toothbrushing per day might reduce oral cavity cancer risk by 6%, pharyngeal cancer risk by 11%, laryngeal cancer risk by 3%, oesophageal cancer risk by 6% and gastric cancer risk by 4%. CONCLUSIONS This meta-analysis suggested the negative relationship between frequency of toothbrushing and risk of gastric and UADT cancers. Toothbrushing may be a protective factor for gastric and UADT cancers. However, this association must be further validated through large prospective studies.

Abstract
BACKGROUND Regular/frequent dental visits, at least annually, can aid in reducing the public health burden of head and neck cancers (HNCs) by facilitating earlier detection of the disease. The aim of this study was to conduct a quantitative assessment of any independent association between past dental visits/check-ups and incidence of cancers of HN/upper aerodigestive tract (UADT) and oral cavity worldwide. METHODS PubMed, CINAHL, and Cochrane databases were searched for all observational studies published until August 2017 in any language that assessed an association of past dental visits/dental check-ups among the incident cases of HNC/UADT cancers. Screening and quality assessment of the articles was performed by two independent reviewers. Three different meta-analyses were conducted: two based on the incident cancer reported in the studies (HNCs/cancers of UADT and oral cavity); another included all studies irrespective of the type of cancer reported with the frequency of past dental visits as subgroups. RESULTS Searches retrieved 3164 titles: after removing duplicates, 1377 remained. Of these, 62 were reviewed in full, but only 38 were eligible for inclusion. Under the random effects model, odds of past never/irregular/not frequent dental visits were greater in HNC cases and oral cancer cases as compared to the hospital-based/population-based controls [HNCs-unadjusted odds ratio (OR) 2.24; 95% confidence interval (CI) 1.89 to 2.65) and (oral cancers-OR 1.93; 95% CI 1.47 to 2.52]. Similar results were observed for all cancers with frequency of past dental visits as subgroup analysis (OR 2.01; 95% CI 1.76 to 2.30). Meta-regression findings indicate that none of the subgroup influenced the effect estimates for incidence of cancers. There was no publication bias in our study. CONCLUSION This systematic review and meta-analysis indicates that individuals with never/irregular/not frequent dental visits are more likely to be incident cases of HNCs/UADT cancers.

Abstract
Oral squamous cell carcinomas (OSCC) are among the commonest cancers in South East Asia and more so in the Indian subcontinent. The role of tobacco and alcohol in the causation of these cancers is well-documented. Poor oral hygiene (POH) is often seen to co-exist in patients with OSCC. However, the role of poor oral hygiene in the etio-pathogenesis of these cancers is controversial. We decided to evaluate the available literature for evaluating the association of POH with OSCC. A thorough literature search of English-language articles in MEDLINE, PubMed, Cochrane Database of Systematic Reviews, and Web of Science databases was conducted, and 93 relevant articles were short-listed. We found that POH was strongly associated with oral cancers. It aids the carcinogenic potential of other known carcinogens like tobacco and alcohol. Even on adjusting for known confounding factors like tobacco, alcohol use, education, and socio-economic strata, presence of POH exhibits higher odds of developing oral cancer.

Abstract
The objective of this study was to determine of oral and oropharynx cancer mortality rate and the results were analyzed by applying the Spatial Analysis of Empirical Bayesian Model. To this end, we used the information contained in the International Classification of Diseases (ICD-10), Chapter II, Category C00 to C14 and Brazilian Mortality Information System (SIM) of Minas Gerais State. Descriptive statistics were observed and the gross rate of mortality was calculated for each municipality. Then Empirical Bayesian estimators were applied. The results showed that, in 2012, in the state of Minas Gerais, were registered 769 deaths of patients with cancer of oral and oropharynx, with 607 (78.96%) men and 162 (21.04%) women. There was a wide variation in spatial distribution of crude mortality rate and were identified agglomeration in the South, Central and North more accurately by Bayesian Estimator Global and Local Model. Through Bayesian models was possible to map the spatial clustering of deaths from oral cancer more accurately, and with the application of the method of spatial epidemiology, it was possible to obtain more accurate results and provide subsidies to reduce the number of deaths from this type of cancer.

Abstract
Smokeless tobacco consumption, which is widespread throughout the world, leads to oral submucous fibrosis (OSMF), which is a long-lasting and devastating condition of the oral cavity with the potential for malignancy. In this review, we mainly focus on the consumption of smokeless tobacco, such as paan and gutkha, and the role of these substances in the induction of OSMF and ultimately oral cancer. The list of articles to be examined was established using citation discovery tools provided by PubMed, Scopus, and Google Scholar. The continuous chewing of paan and swallowing of gutkha trigger progressive fibrosis in submucosal tissue. Generally, OSMF occurs due to multiple risk factors, especially smokeless tobacco and its components, such as betel quid, areca nuts, and slaked lime, which are used in paan and gutkha. The incidence of oral cancer is higher in women than in men in South Asian countries. Human oral epithelium cells experience carcinogenic and genotoxic effects from the slaked lime present in the betel quid, with or without areca nut. Products such as 3-(methylnitrosamino)-proprionitrile, nitrosamines, and nicotine initiate the production of reactive oxygen species in smokeless tobacco, eventually leading to fibroblast, DNA, and RNA damage with carcinogenic effects in the mouth of tobacco consumers. The metabolic activation of nitrosamine in tobacco by cytochrome P450 enzymes may lead to the formation of N-nitrosonornicotine, a major carcinogen, and micronuclei, which are an indicator of genotoxicity. These effects lead to further DNA damage and, eventually, oral cancer.

Abstract
BACKGROUND Patients covered by Medicaid insurance appear to have poorer cancer outcomes. Herein, the authors sought to test whether Medicaid was associated with worse outcomes among patients with head and neck cancer (HNC). METHODS The records of 1698 patients with squamous cell HNC without distant metastatic disease were retrospectively reviewed from an institutional database between 1998 and 2011. At the time of diagnosis, insurance status was categorized as Medicaid, Medicare/other government insurance, or private insurance. Outcomes including locoregional control (LRC) and overall survival (OS) were estimated using the Kaplan-Meier method and Cox regression multivariate analysis (MVA). RESULTS The median follow-up for all patients was 35 months. Medicaid patients comprised 11% of the population; the remaining patients were privately insured (56%) or had Medicare/government insurance (34%). On MVA, Medicaid patients were younger, were current smokers, had higher tumor T and N classifications, and experienced a longer time from diagnosis to treatment initiation (all P<.005). Medicaid insurance status was associated with a deficit of 13% in LRC (69% vs 82%) and 26% in OS (46% vs 72%) at 3 years (all with P<.001). A time from diagnosis to treatment initiation of >45 days was found to be associated with worse 3-year LRC (77% vs 83%; P = .009) and OS (68% vs 71%; P = .008). On MVA, Medicaid remained associated with a deficit in LRC (P = .002) and OS (P<.001). CONCLUSIONS Patients with Medicaid insurance more often present with locally advanced HNC and experience a higher rate of treatment delays compared with non-Medicaid patients. Medicaid insurance status appears to be independently associated with deficits in LRC and OS. Improvements in the health care system, such as expediting treatment initiation, may improve the outcomes of patients with HNC. Cancer 2016;122:3529-3537. © 2016 American Cancer Society.

Abstract
This narrative review aims to summarize the current controversy on the balance between ethanol and phytochemicals in wine, focusing on light drinking and oral cancer. Extensive literature search included PUBMED and EMBASE databases to identify in human studies and systematic reviews (up to March 2015), which contributed to elucidate this issue. Independently from the type of beverage, meta-analyses considering light drinking (≤1 drinks/day or ≤12.5 g/day of ethanol) reported relative risks (RR) for oral, oro-pharyngeal, or upper aero-digestive tract cancers, ranging from 1.0 to 1.3. One meta-analysis measured the overall wine-specific RR, which corresponded to 2.1. Although little evidence exists on light wine intake, phytochemicals seem not to affect oral cancer risk, being probably present below the effective dosages and/or due to their low bioavailability. As expected, the risk of oral cancer, even in light drinking conditions, increases when associated with smoking habit and high-risk genotypes of alcohol and aldehyde dehydrogenases.

Abstract
The prevalence of oral cancers (OC) is high in Asian countries, especially in South and Southeast Asia. Asian distinct cultural practices such as betel-quid chewing, and varying patterns of tobacco and alcohol use are important risk factors that predispose to cancer of the oral cavity. The aim of this review is to provide an update on epidemiology of OC between 2000 and 2012. A literature search for this review was conducted on Medline for articles on OC from Asian countries. Some of the articles were also hand searched using Google. High incidence rates were reported from developing nations like India, Pakistan, Bangladesh, Taiwan and Sri Lanka. While an increasing trend has been observed in Pakistan, Taiwan and Thailand, a decreasing trend is seen in Philippines and Sri Lanka. The mean age of occurrence of cancer in different parts of oral cavity is usually between 51-55 years in most countries. The tongue is the leading site among oral cancers in India. The next most common sites in Asian countries include the buccal mucosa and gingiva. The 5 year survival rate has been low for OC, despite improvements in diagnosis and treatment. Tobacco chewing, smoking and alcohol are the main reasons for the increasing incidence rates. Low socioeconomic status and diet low in nutritional value lacking vegetables and fruits contribute towards the risk. In addition, viral infections, such as HPV and poor oral hygiene, are other important risk factors. Hence, it is important to control OC by screening for early diagnosis and controlling tobacco and alcohol use. It is also necessary to have cancer surveillance at the national-level to collect and utilise data for cancer prevention and control programs.

Abstract
PURPOSE The identification of experienced and knowledgeable dental specialists to provide appropriate oral care for cancer patients, as well as the integration of this care within general oncology management, may be a challenge. This paper discusses the general and additional requirements for dental care providers to support the cancer patient and provide prevention and/or treatment for oral complications of cancer therapy. METHODS We performed a literature review of specific issues regarding the oral cavity and adjacent structures in the cancer patient, including detection and early diagnosis of oral malignancy. We incorporated the systemic effects of cancer and its therapy that affect oral disease and treatment. We present a summary of how to seek expert dental care for cancer patients and for referral from the dental and medical community. RESULTS Due to the complexity conferred by the disease and its treatment, cancer patients require educated, experienced dentists for treatment and/or prevention of oral-related morbidity. Correct diagnosis and evidence-based prophylactic and therapeutic oral care can significantly improve patient quality of life and reduce morbidity and healthcare costs. CONCLUSIONS The knowledge and expertise of dental professionals regarding prevention/treatment of complications and secondary malignant lesions in cancer patients are critical. Integration of oral care with the oncology care and in survivors requires effective communication between dental and medical providers beginning ideally at diagnosis. These clinicians may be identified at the cancer center, nearby hospital dental programs, and, less commonly, in the community.

Abstract
With respect to addressing oral cancer as a public health problem and the need to conduct early diagnosis to ensure a favorable prognosis for patients, the city of Marilia in the state of São Paulo stages an annual campaign for prevention and early detection of oral cancer. This study sets out to evaluate the participatory planning of the teams at health facilities, seeking to list the difficulties encountered and strategies adopted over a five-year period (2006-2011) by analyzing the coverage of oral examinations for prevention and detection of disease. Strategies for tackling difficulties, issues of epidemiological coordination and surveillance raised by dentists, generated an increase in the coverage of tests performed in the population (> 60 years) from 21% in 2006 to 62% in 2011. The conclusion is that the development of strategies with the participation of health teams produces quite encouraging results, ensuring that the lesions of oral cancer are diagnosed and treated early from the perspective of a more favorable prognosis.

Abstract
PURPOSE The relationship between duration of cigarette smoking and the risk of oropharyngeal cancer has not been studied in the general Japanese population. Thus, the aim of the present study was to examine the relationship between the duration of cigarette smoking and the risk of oropharyngeal cancer mortality in the Japanese population. METHODS In this large cohort study, 32,989 men and 63,894 women, ages 40-79 years, who completed health check-ups in Ibaraki Prefecture, Japan, in 1993 were followed through 2008. Oropharyngeal cancer mortality was identified by death certificates. Smoking habits were divided into five categories, and years of cigarette smoking and pack-year classifications were divided into four categories. Hazard ratios and 95% confidence intervals for oropharyngeal cancer mortality were calculated by use of the Cox proportional hazards regression models. RESULTS During the follow-up period, deaths from oropharyngeal cancer occurred in 38 of 32,989 men and 31 of 63,894 women. The multivariate hazard ratios for oropharyngeal cancer mortality were significantly greater for those subjects currently smoking for 40 years or longer (hazard ratio: 4.22, 95% confidence interval: 1.23-14.51), and they were greater with longer years of cigarette smoking among men (P for trend = .027). CONCLUSIONS Smoking duration can be a risk factor for oropharyngeal cancer mortality in the Japanese population.

Abstract
INTRODUCTION This study investigated the knowledge about oral cancer in a representative population sample of the state of Schleswig-Holstein, Germany. MATERIAL AND METHODS A representative survey (n=1000) was carried out by means of computer-aided phone interviews among the population of Schleswig-Holstein. Descriptive statistics of demographic variables and responses to the questionnaires were reported by means of counts and percentages. Knowledge about diagnostic items and risk factors was further analysed for socioeconomic factors. RESULTS 66% of the sample was aware that oral cancer lesions are most often diagnosed at an advanced stage. Only 20-40% knew the two most common sites. More than 70% identified tobacco consumption and a prior oral cancer lesion as risk factors, consumption of alcohol and older age were identified by about 50%. The detailed analysis showed a relationship between a low level of knowledge and certain socioeconomic factors, e.g. older age, low level of education and employment. CONCLUSIONS This survey highlighted a general lack of public awareness about signs and symptoms of oral cancer and its risk factors. A low level of knowledge was associated with a low level of certain socioeconomic factors. These results should have implications for the design of a state-wide public awareness campaign.

Abstract
The classification of sites in tumors of the oral cavity, oropharynx, pharynx, and hypopharynx varies in the literature. More than 90% of these tumors of the mucosal lining are classified as squamous cell carcinoma developed from premalignant lesions such as leukoplakia and erythroleukoplakia. These carcinomas are associated to environmental and lifestyle risk factors, among which tobacco and alcohol play a major role. In addition to tobacco smoking, tobacco chewing is another risk factor as well as chewing betel quid and areca nut in Asia. Certain strains of virus, such as the sexually transmitted human papilloma virus, also play a carcinogenetic role. The temporal trends in incidence of these tumors relate to environmental factors; there is an increase in tendency in countries without prevention and a decrease in countries having an active policy of prevention of alcohol and tobacco consumption. In contrast, an increased incidence occurs in the world at tumor sites related to human papilloma virus infection in relation to changes in sexual habits.

Abstract
We aimed to investigate the association between smoking, alcoholic consumption, and betel quid chewing with oral cancer in a prospective manner. All male patients age ≥18 years who visited our clinic received an oral mucosa inspection. Basic data including personal habits were also obtained. A multivariate logistic regression model was utilized to determine relevant risk factors for developing oral cavity cancer. A total of 10,657 participants were enrolled in this study. Abnormal findings were found in 514 participants (4.8%). Three hundred forty-four participants received biopsy, and 230 patients were proven to have oral cancer. The results of multivariate logistic regression found that those who smoked, consumed alcohol, and chewed betel quid on a regular basis were most likely to develop cancer (odds ratio: 46.87, 95% confidence interval: 31.84-69.00). Therefore, habitual cigarette smokers, alcohol consumers, and betel quid chewers have a higher risk of contracting oral cancer and should receive oral screening regularly so potential oral cancer can be detected as early as possible.

Abstract
The objective is to assess the role of socio-economic factors and health-seeking behavior in treatment delay in oral and oropharyngeal cancer in our population. This article adapts-design: prospective study and setting: tertiary care centre. We studied 153 patients with oral and oropharyngeal squamous cell carcinoma who were managed in the department of otolaryngology and head and neck surgery between January 2006 and December 2007. There were 127 male patients (83%) and 26 females (17%) with ages ranging from 22 years to 70 years. Fifty-nine patients (39%) presented to us with early stage disease (i.e. stage I and II), whereas, 94 patients (61%) presented with late stage disease (i.e. stage III and IV). Of the 59 patients presenting with early stage disease, 20 were illiterate and 39 literate with 28 patients (47%) belonging to low socio-economic status and 32 patients (54%) having an access to primary health centre (PHC). Of the 94 patients presenting with late stage disease, 53 were illiterate and 41 literate with 58 patients (62%) belonging to low socio-economic status and 38 patients (40%) having an access to primary health centre. Literacy, socio-economic status, access to primary health centre and health-seeking behavior of our population has a significant association with the stage of presentation of patients with oral and oropharyngeal cancer.

Abstract
BACKGROUND Only a few studies have explored the relation between coffee and tea intake and head and neck cancers, with inconsistent results. METHODS We pooled individual-level data from nine case-control studies of head and neck cancers, including 5,139 cases and 9,028 controls. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI), adjusting for potential confounders. RESULTS Caffeinated coffee intake was inversely related with the risk of cancer of the oral cavity and pharynx: the ORs were 0.96 (95% CI, 0.94-0.98) for an increment of 1 cup per day and 0.61 (95% CI, 0.47-0.80) in drinkers of >4 cups per day versus nondrinkers. This latter estimate was consistent for different anatomic sites (OR, 0.46; 95% CI, 0.30-0.71 for oral cavity; OR, 0.58; 95% CI, 0.41-0.82 for oropharynx/hypopharynx; and OR, 0.61; 95% CI, 0.37-1.01 for oral cavity/pharynx not otherwise specified) and across strata of selected covariates. No association of caffeinated coffee drinking was found with laryngeal cancer (OR, 0.96; 95% CI, 0.64-1.45 in drinkers of >4 cups per day versus nondrinkers). Data on decaffeinated coffee were too sparse for detailed analysis, but indicated no increased risk. Tea intake was not associated with head and neck cancer risk (OR, 0.99; 95% CI, 0.89-1.11 for drinkers versus nondrinkers). CONCLUSIONS This pooled analysis of case-control studies supports the hypothesis of an inverse association between caffeinated coffee drinking and risk of cancer of the oral cavity and pharynx. IMPACT Given widespread use of coffee and the relatively high incidence and low survival of head and neck cancers, the observed inverse association may have appreciable public health relevance.

Abstract
OBJECTIVES To examine whether denture use and recurrent sores caused by ill-fitting dentures are associated with intra-oral squamous cell carcinoma (IO-SCC) in individuals exposed to tobacco. METHODS We conducted a hospital-based case-control study. The study population 124 patients wi th IO-SCC and the same number of controls (individually paired according to gender and age) recruited from outpatient units of the same hospital. Conditional logistic regression analysis assessed the effect of denture use and recurrent oral sores by ill-fitting dentures, adjusted by covariates on the lifetime exposure to alcohol and tobacco, socioeconomic standings, and dietary patterns. RESULTS The use of dentures showed no association with IO-SCC [adjusted odds ratio (OR) 1.40, 95 percent confidence interval 0.51-3.87, P = 0.513] in an assessment controlled by socioeconomic position, lifetime exposure to alcohol and tobacco, and dietary patterns. However, the report of recurrent sores caused by ill-fitting dentures showed significant association with the disease (adjusted OR 4.58, 95 percent confidence interval 1.52-13.76, P = 0.007). CONCLUSIONS The association between recurrent oral sores caused by ill-fitting dentures and squamous cell carcinoma of the mouth in smokers is in agreement with the hypothesis that the chronic physical irritation of oral mucosa contributes to the topical carcinogenic effect of tobacco, which must be taken into careful consideration in the planning of dental services for adults and the elderly.

Abstract
This study analyzed oral cancer epidemiology based on histopathology reports from a public laboratory in Mato Grosso, Brazil, after a specific policy was implemented for treating oral and facial diseases in the State. This was a cross-sectional epidemiological study, based on 1,324 histopathology reports issued from January 2005 to December 2006. The study identified 44 cases of oral cancer, or 3% of all oral lesions, and analyzed them in relation to the following variables: histological type, gender, age, and patient's place of residence (capital versus rest of State). The most common histological type was squamous cell carcinoma. Most of the diagnoses occurred in men in their 50s and 60s living in the interior of the State. During two years in operation, this public oral pathology service had recorded a considerable number of oral cancer cases.

Abstract
As doenças crônico-degenerativas representam um grande problema de saúde pública, necessitando de levantamento e controle mais efetivos destas enfermidades por parte dos órgãos públicos. O objetivo deste estudo foi correlacionar os índices de mortalidade por câncer oral nas capitais do Brasil no período de 1998 a 2002 com indicadores sócio-econômicos do Censo Demográfico de 2000, por meio de um estudo do tipo ecológico. Os dados foram extraídos do Sistema de Informação de Mortalidade (Ministério da Saúde/DATASUS), para os anos de 1998-2002. Os indicadores sócio-econômicos foram obtidos a partir do Atlas do Desenvolvimento Humano no Brasil. Após coleta dos dados, a análise estatística foi realizada usando-se o índice de correlação de Pearson. Observaram-se correlações positivas e significativas entre os indicadores sócio-econômicos (Índice de Desenvolvimento Humano-Municipal - IDH-M, IDH-M renda, IDH-M educação, IDH-M longevidade e renda per capita), e correlação negativa e significante para os indicadores sócio-econômicos índice de Gini e mortalidade infantil. Apesar das limitações do estudo e da provável problemática de sub-registros nas capitais menos desenvolvidas, o presente trabalho encontrou correlações estatisticamente significantes entre os indicadores sócio-econômicos selecionados e o índice de mortalidade por câncer oral.

Abstract
This study analyzed characteristics of oral cancer patients from Tehran, Iran, and their tumors. Data came from the patient records of 30 major hospitals in Tehran. Patients (n = 1042), diagnosed with invasive oral cancer in 1993-2003, were classified by primary tumor site according to ICD-10 (C00-C10). Data were analyzed separately for lip, oral cavity and salivary gland tumors. Statistical evaluation included chi and t-test. Of all cases, 59% were male. Age for all cases ranged from 6-103 years, mean age was 58.8 years (SD 16; median 62); 89% were older than 40. Tumor site breakdown was 65% oral cavity, 21% major salivary glands and 14% lip. A clear gender difference (P < 0.001) appeared regarding the primary tumor sites: women dominated in oral cavity cancers and men in lip cancers. The most common cancer site was the tongue (32%), accounting for 50% of the oral cavity cancers. Histologically, 88% of all oral cavity and lip cancers were squamous cell carcinomas, 10% of those were in age </=40, 42% in ages 41-64 and 48% >/= age 65. At the time of diagnosis, 59% of oral cavity cancers and 29% of lip cancers were at stage III or IV (P < 0.001). The results emphasize an urgent need for a national program focusing on early detection of oral cancers, including educational information addressed to oral health professionals.

[PMID: 16987693 DOI: 10.1016/j.oraloncology.2006.02.012] [Citation(s) in RCA: 63] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2006] [Revised: 02/23/2006] [Accepted: 02/24/2006] [Indexed: 11/25/2022]
Abstract
The early detection of oral squamous cell carcinoma by non-invasive methods has the potential to hasten diagnosis and thus lessen the morbidity associated with tumour therapy. Dielectrophoresis (DEP) can non-invasively determine electrophysiological parameters such as conductivity and permittivity of cellular cytoplasm and membrane. The present study demonstrates that DEP can be utilised to characterise H357 and UP cells and reveals that there are significant differences in these parameters between malignant and more normal epithelial cell lines. The present results suggest that DEP has potential for the early detection of cancerous from non-cancerous cells in a clinical setting.
