Malignant neoplasms of the mouth represent approximately 5% of all malignancies on human beings in the world. More than 90% of cancer cases that occur in the mouth are squamous cell carcinomas. Objective: To know the frequency of oral squamous cell carcinoma in the population of Volta Redonda , Rio de Janeiro, Brazil, in order to confirm their relation according to gender, age and its localization in the mouth. Methods: A total of 5,880 records histopathological diagnoses, belonging to the collection of the Department of Oral Pathology, at the Dentistry Course of Centro Universitario de Volta Redonda, obtained from 1990 until 2000. Results: The rate that was found was 85,4% for males, and 14,6 % for females, yielding a ratio of 5,8:1; the ages ranged from 3 to 94 years old, the average age being 53.48 years old, and the tongue was the place it occurred the most. Conclusion: The data found in this study is similar to that available in the studied literature.
Oral carcinoma epidemiology in Paraná State, Southern Brazil
Cadernos de Saúde Pública, 2009
Oral carcinoma is the sixth most frequent type of cancer in the world and the seventh most common in Brazil (the country with the highest incidence in Latin America). Mean five-year survival remains one of the lowest among the main cancers, thus justifying studies that contribute to the development of preventive strategies. The aim of this study was to compare the epidemiological, clinical, and histological characteristics of 91 patients with oral carcinoma. Mean age was 58.62 ± 10.46 years, and male-to-female ratio was 6.6:1.0 (79 men and 12 women). European descendants predominated with 79 patients (86.8%). Eightyfive individuals (93.4%) smoked and 70 (76.9%) consumed alcohol regularly. Anatomical distribution of tumors was: 27 (29.7%) tongue; 18 (19.8%) floor of mouth; 11 (12.1%) oropharynx; and 11 (12.1%) oral mucosa. Fifty-seven patients (62.6%) presented lymph node involvement and three (3.3%) had distant metastases. Surgery and radiotherapy were used in 43.2% of patients. With the exception of the male/female ratio (which was higher), our data are consistent with previous studies on oral carcinoma patients.

Considering the role of epidemiological information in planning and effective interventions, the purpose of this study was to systematically review the epidemiology of squamous cell carcinoma in Brazil. We searched the PubMed, LILACS, BBO and Cochrane databases using keywords "oral squamous cell carcinoma", "oral squamous cell carcinoma", "oral squamous cell carcinoma" and their equivalents in English and Spanish, in combination with epidemiology, prevalence, frequency, and Brazil by 2018, excluding studies that did not address the epidemiology of this neoplasm or those conducted in other countries. The mean age of the patients was 56.6 years, with a higher prevalence in males 3.29: 1, mainly located in tongue, 42% and mouth floor 22%. Associated risk factors are tobacco (72.85%) and alcohol (66.65%). It was observed that 47% of patients present with regional metastases at the time of cancer discovery. According to the observed observational studies it can be concluded that the epidemiological data of Brazil are high in comparison to other countries, especially the number of metastases, indicating the late diagnosis of the disease ABSTRACT Considering the role of epidemiological information in planning and effective interventions, the purpose of this study was to systematically review the epidemiology of squamous cell carcinoma in Brazil.

, with histological confirmation. Data were analyzed according district of residence, gender, age, topographic location of the tumor, histological type, degree of differentiation, and stage (TNM). Results: During this retrospective descriptive study, 1041cases were reported in both genders. Men were more affected than women in a 3:1 proportion. The number of diagnosed oral carcinoma cases increased in the 5th decade of age (19.69% ± 2.42%) and progressively decrease after the 7th (18.35% ± 2.35%). The most affected region was the tongue (C01 + C02) (43.51% ± 3.01%), followed by the floor of the mouth (C04) (17.48% ± 2.31%). The most prevalent histological entity was squamous cell carcinoma (93.37% ± 10.90%) in grade I (44.20% ± 5.86%). Regarding TNM stages, the most frequent was stage IV (42.00% ± 3.89%). Conclusion: The epidemiological profile of oral malignant neoplasms found in our study is in accordance with the existing literature. More epidemiological studies, as well as awareness and prevention programs, should be conducted in this area in Portugal.
Epidemiological and histopathological pattern of primary oral carcinomas in Venezuela
Objectives: The aim of this study was to determine gender and age-specific distribution of primary oral carcinomas diagnosed in Oral Pathology Services as well as to describe the anatomical and histological characteristics of these tumours. Methods: A descriptive prospective study of the epidemiological and pathological profile of primary oral carcinomas was conducted for 5 years in Caracas-Venezuela. The study was restricted to selected Oral & Maxillofacial Surgery and Oral Medicine Services which pathology analysis have been performed routinely by the same group of oral pathologists. Patients of first diagnosed oral carcinomas were evaluated covering the period of diagnosis of 2005 to 2010. After completing an ethical consent every patient was evaluated and incisional biopsy taken. Data was collected and percentage distribution of oral carcinomas by age, gender and anatomical site was calculated. Histopathological features were evaluated and described.

Aim To perform an epidemiological and clinical analysis of cases of oral cancer (OC) and potentially malignant disorders (PMDs). Subjects and methods This retrospective study was based on the analysis of data from 631 patients who attended a clinic of the Interdisciplinary League of Oral Cancer (LINCCO) of a public university of northeastern Brazil over a time period of 12 years. Sociodemographic, economic, and clinical variables were investigated. Descriptive, bivariate, and multivariate statistical analyses using Poisson regression were performed. Results During the analyzed period, 19.3% (n = 122) of cases were related to diagnoses of some type of OC or PMDs. The majority of patients were male (60.7%) and in the fifth (22.0%) or sixth (23.7%) decades of life. The reported smoking and alcohol consumption were 27.0% and 27.9%, respectively. The most prevalent lesions were actinic cheilitis (48.4%) and squamous cell carcinoma (SCC) (23.8%). The most affected anatomical region was the lower lip (45.1%). The prevalence of smoking was higher among those who presented with OC [prevalence ratio (PR) = 2.56, 95% confidence interval (CI) = 1.54-4.24, p < 0.001)] compared to those who presented with a PMD. Conclusion Public health managers and the scientific community should continue to direct efforts to raise public awareness about protective and preventive measures for OC and PMDs, including early diagnosis and frequent visits to the dentist. Otherwise, the rates of these injuries may continue to grow exponentially, significantly impacting the health indicators of the population.

Introduction: As one of the most common human malignancies, oral and oropharyngeal cancer represents a challenge in global public health. Objective: To describe the lesions diagnosed during an oral cancer prevention campaign carried out in Fernandópolis, Brazil, in 2018. Material and methods: Patients treated at the basic health units in Fernandópolis on the day of the campaign were examined by a previously trained dentist who looked for suggestive oral lesions with malignant potential. Patients with suspicious lesions were scheduled for re-evaluation by an oral disease specialist to obtain the correct diagnosis of the lesion. Results: 956 patients were examined during the campaign. Among them, 75 (7.84%) were referred, however, 66 (88%) attended for reassessment and proper diagnostic management by the dentist specializing in oral diseases. Were diagnosed 59 benign oral lesions and 23 variations from normality, no patient was diagnosed with malignant oral lesion. Conclusion: The absence of a diagnosis of oral cancer during the campaign suggests the need to reassess its methodology, aiming to reach a target audience with a higher risk of carrying oral lesions that lead to malignant manifestations. It is also noteworthy that health professionals need better training to clinically recognize lesions suggestive of oral cancer.
