          Abstract

          RESUMO: Objetivo: Esta pesquisa objetivou conhecer a associação entre fatores como: idade, sexo, cor da pele, ocupação, nível de escolaridade, situação conjugal, local de residência, tabagismo, etilismo e o câncer de boca em indivíduos de uma cidade do Nordeste do Brasil entre 2002 e 2012. Métodos: Este estudo é do tipo caso-controle. O grupo caso foi formado por 127 pessoas atendidas no Centro de Referência de Lesões Bucais com diagnóstico histopatológico de carcinoma de células escamosas (CCE) de boca. O grupo controle foi composto por 254 indivíduos desse mesmo centro. Consideraram-se dois controles para cada caso. Casos e controles foram ajustados por sexo e idade. Foram realizadas as análises univariada e bivariada (teste do χ2 de Pearson) para verificar a associação entre a variável dependente (câncer de boca) e as variáveis independentes; foram calculados a odds ratio (OR) e o intervalo de confiança de 95% (IC95%). Por fim, na análise multivariada, foi utilizado o modelo hierarquizado com regressão logística para avaliar as inter-relações entre as variáveis independentes e o câncer de boca. Resultados: O consumo de mais de 20 cigarros por dia [OR = 6,64; IC95% 2,07 - 21,32; p ≤ 0,001], a alta ingestão de bebida alcoólica [OR = 3,25; IC95% 1,03 - 10,22; p ≤ 0,044] e o consumo sinérgico de tabaco e álcool [OR = 9,65; IC95% 1,57 - 59,08; p ≤ 0,014] são os fatores de risco mais importantes para o câncer bucal. Conclusão: Concluiu-se que tabagismo e etilismo são os fatores mais importantes para o desenvolvimento do câncer bucal. Fatores sociodemográficos não apresentaram associação com essa neoplasia após ajuste para tabagismo e etilismo.

          ABSTRACT: Objective: This study aimed at assessing the association between factors such as age, sex, skin color, occupation, educational level, marital status, place of residence, and tobacco and alcohol consumptions and oral cancer in individuals in a city in the northeast of Brazil between 2002 and 2012. Methods: This is a case-control study. The case group consisted of 127 people attended at the Oral Injury Reference Center with histopathological diagnosis of oral squamous cell carcinoma. The control group consisted of 254 individuals treated at the same center. The study considered two controls for each case. The cases and controls were adjusted according to sex and age. Univariate and bivariate analyses were performed (Pearson χ2-test) to verify the correlation between the dependent variable (oral cancer) and the independent variables; odds ratio (OR) and the confidence interval of 95% (95%CI) were calculated. Finally, in the multivariate analysis, it was used as the hierarchical model with logistic regression to explain the interrelationships between the independent variables and oral cancer. Results: Consumption of more than 20 cigarettes per day [OR = 6.64; 95%CI 2.07 - 21.32; p ≤ 0.001], an excessive alcohol consumption [OR = 3.25; 95%CI 1.03 - 10.22; p ≤ 0.044], and the synergistic consumption of tobacco and alcohol [OR = 9.65; 95%CI 1.57 - 59.08; p ≤ 0.014] are the most important risk factors for oral cancer. Conclusion: It was concluded that tobacco and alcohol consumptions are the most important factors for the development of oral cancer. Sociodemographic factors were not associated with this neoplasm after adjusting for smoking and drinking.

          Socioeconomic inequalities and oral cancer risk: a systematic review and meta-analysis of case-control studies.

          There is uncertainty and limited recognition of the relationship between socioeconomic inequalities and oral cancer. We aimed to quantitatively assess the association between socioeconomic status (SES) and oral cancer incidence risk. A systematic review of case-control studies obtained published and unpublished estimates of the SES risk related to oral cancer. Studies were included which reported odds ratios (ORs) and corresponding 95% CIs of oral cancer with respect to SES, or if the estimates could be calculated or obtained. Meta-analyses were performed on subgroups: SES measure, age, sex, global region, development level, time-period and lifestyle factor adjustments; while sensitivity analyses were conducted based on study methodological issues. Forty-one studies provided 15,344 cases and 33,852 controls which met our inclusion criteria. Compared with individuals who were in high SES strata, the pooled ORs for the risk of developing oral cancer were 1.85 (95%CI 1.60, 2.15; n = 37 studies) for those with low educational attainment; 1.84 (1.47, 2.31; n = 14) for those with low occupational social class; and 2.41 (1.59, 3.65; n = 5) for those with low income. Subgroup analyses showed that low SES was significantly associated with increased oral cancer risk in high and lower income-countries, across the world, and remained when adjusting for potential behavioural confounders. Inequalities persist but are perhaps reducing over recent decades. Oral cancer risk associated with low SES is significant and comparable to lifestyle risk factors. Our results provide evidence to steer health policy which focus on lifestyles factors toward an integrated approach incorporating measures designed to tackle the root causes of disadvantage.

            An analysis of risk factors for oral cancer in young people: a case-control study.

            The incidence of oral cancer amongst young adults is increasing in many European and high incidence countries. The aim of this study was to evaluate the major risk factors for oral cancer in young adults using a case-control design. A sample of 116 patients aged 45 years and younger, diagnosed with squamous cell carcinoma of the oral cavity between 1990 and 1997 from the south east of England were included. Two-hundred and seven controls who had never had cancer, matched for age, sex and area of residence, were recruited. The self-completed questionnaire contained items about exposure to the following risk factors: tobacco products, cannabis, alcohol and diet. Conditional logistic analyses were conducted adjusting for social class, ethnicity, tobacco and alcohol habits. All tests for statistical significance were two-sided. The majority of oral cancer patients reported exposure to the major risk factors of tobacco and alcohol even at this younger age. The estimated risks associated with tobacco or alcohol were low (OR range: 0.6-2.5) among both males and females. Only smoking for 21 years or more produced significantly elevated odds ratios (OR=2.1; 95% CI: 1.1-4.0). Exposure associated with other major risk factors did not produce significant risks in this sample. Long term consumption of fresh fruits and vegetables in the diet appeared to be protective for both males and females. The results suggest that although this younger sample exhibit similar behavioural risk factors to older oral cancer patients, the low odds produced in addition to the relatively short duration of exposure, suggest that factors other than tobacco and alcohol may be implicated in the development of oral cancer in these younger patients.

              Tobacco, oral cancer, and treatment of dependence.

              Tobacco dependence is recognised as a life-threatening disorder with serious oral health consequences which responds to treatment in the form of behavioural support and medication. While cigarette smoking is the most hazardous and prevalent form of tobacco use in the west, consideration also needs to be given to other forms such as bidi smoking in India, reverse smoking by several rural populations and use of snuff and chewing tobacco. The evidence that the use of tobacco is the major risk factor for oral cancer and potentially malignant lesions of the mouth is clear. Counseling to quit smoking is not applied in a systematic or frequent manner to people presenting with potentially malignant lesions of the oral cavity. This review makes recommendations for interventions by health professionals to encourage and aid cessation of tobacco use as a part of prevention of oral cancer.
