Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology, 2020
Background: To analyze the trends of oral and oropharyngeal cancer mortality in Uruguay between 1997 and 2014 according to sex and age groups and its possible association with sociodemographic factors. Material and Methods: A time-series ecological study using secondary data was performed. The data about mortality due to oral and oropharyngeal cancers were obtained from the Statistics Vitals Department of the Public Health Ministry of Uruguay. To estimate the mortality trends of the historical series, by sex, anatomical site and age groups, linear regressions generated by the Prais-Winsten procedure were used. Results: The analysis of mortality trends for oral cavity and oropharyngeal cancers in Uruguay indicated that the global mortality rate was stable over the studied period. The women's mortality rate increased from 0.51 per 100,000 in 1997 to 0.65 per 100,000 in 2014 while for men, rates per 100,000 went from 3.22 in 1997 to 2.20 per 100,000 in 2014. Mortality from oral cancer in men decreased between 1997 and 2014. Mortality by oropharyngeal cancer, irrespective of sex, remained stable. Analysis by cancer site revealed decreasing trends tumors situated in the base of the tongue and gum. Years of education, unemployment, smoking and Gini index were not associated with mortality trends. Conclusions: The overall mortality from oral and oropharyngeal cancer in Uruguay has remained constant in the period between 1997 and 2014. Oral cancer mortality decreased in men and increased in women and decreased at the base of the tongue. It's necessary to continue monitoring the behavior of these diseases.

Trends and Spatial Patterns of Oral Cancer Mortality in Ecuador, 2001–2016
International Journal of Dentistry, 2018
The aims of this study were to describe the temporal trend of OC from 2001 to 2016 and to analyze the space and space-time clusters of high mortality due to OC in Ecuador from 2011 to 2016. Methods. The present study is a mixed ecological study; the time trends were obtained using a Joinpoint regression model, space-time scan statistics was used to identify high-risk clusters, and Global Moran I index was calculated. Results. In Ecuador, between 2001 and 2016, OC caused a total of 1,025 deaths. Crude mortality rates significantly increased, with an APC (annual percentage change) of 2.7% (p = 0.009). The age-standardized mortality rate did not significantly increase (APC: 1.73%; p = 0.08). The most likely cluster was detected in 2015, included 20 cantons. The second cluster included 38 cantons, in the years 2014 to 2016. The Global Moran I index for the study period showed a negative spatial autocorrelation (−0.067; p = 0.37). Conclusion. Mortality due to OC in Ecuador significantly increased over the 16-year study period, the young groups being the most affected. Ecuadorian provinces present high variability in types of OC and cancer rates.

Mortality due to oral and oropharyngeal cancer in Uruguay from 1997 to 2014
Journal of Applied Oral Science
Mortality due to oral and oropharyngeal cancer in Uruguay from 1997 to 2014 Oral and oropharyngeal cancer is considered a public health problem in several countries due to its high incidence and mortality rate. Objective: This study aimed to analyze oral and oropharyngeal cancer mortality in Uruguay from 1997 to 2014 by age, sex and country region. Methodology: A time series ecological study using secondary data was performed. Data on mortality due to oral and oropharyngeal cancers were obtained from the Vital Statistics Department of Uruguay's Ministry of Public Health. Results: The cumulative mortality rate due to oral and oropharyngeal cancer over the study period was of 19.26/100,000 persons in women and 83.61/100.000 in men, with a mean annual rate of 1.75/100,000 in women and 7.60/100,000 in men. Mortality rate from both sites during the study period was 4.34 times higher in men than in women. Malignant neoplasms of other parts of the tongue and base of tongue showed the highest mortality rate. The means of the annual coefficients of deaths were higher for the age groups between 50 and 69 years. Higher mortality rates of oral and oropharyngeal cancer were observed in Artigas (4.63) and Cerro Largo (3.75). Conclusions: Our study described a high mortality rate for oral and oropharyngeal cancer in Uruguay from 1997 to 2014. According to the country's health department, men, tongue cancer, and oral cavity had higher mortality rates, with some variation. Prevention strategies with control of risk factors and early diagnosis are necessary to improve survival in the Uruguayan population.

Malignant neoplasm (MN) mortality worldwide ranks among the first four causes of death, in the 1990 decade (1-4). The aim of this work is to study the eight most frequent MN mortality rates, and especially that one caused by oral cancer (OC) in the province of Cordoba, Argentine Republic, in the period between 1975 and 2000, in order to analyze its characteristics and compare with other populations in America and Europe. The data were provided by the provincial and national Health Ministry and Globocan 2000. The highest male rates were those of Slovakia and France, prevailing lung and bronchus tumors; whereas in females the highest rate was that of breast cancer in the United Kingdom and Germany, and lung cancer in the United States. Regarding to OC in the populations under study, Slovakia and France held the highest rates for both sexes, being Cordoba and Argentina among the lowest values, especially in women. Tongue was the most frequent site in Cordoba (43.5%), followed by saliva...

Objective. To establish the time trends of the frequency and prevalence of oral cavity cancer in regard to age and gender in a 20-years (time period 1989-2008) cohort of Mexicans. Design and Setting. 13,235 head and neck biopsies from the archive of the Oral Pathology Laboratory, Dental School, National Autonomous University of Mexico were revised. The cases with diagnoses of oral cancer were selected. Gender and age at diagnosis was obtained from medical records. The frequency and prevalence of oral cavity cancer and oral squamous cell carcinoma were assessed biannually in regard to the total number of population served by the oral pathology laboratory. The statistical significance of trends was established using the linear logistic regression (curve estimation) test (s 0.05). Results. 298 cases (138 males; 160 females) of oral cancer were included; 167 (92 females; 75 males; female:male ratio: 1.1:1) corresponded to oral squamous cell carcinoma. From 1989 to 2008 the prevalence of oral cancer and oral squamous cell carcinoma increased 200% (s 0.05) and 100% (s 0.000) respectively. The increase of frequency and prevalence was observed in both genders however only in females was significant (s 0.000). We do not identify changes in the age at diagnosis. Conclusions. Oral cancer, specifically oral squamous cell carcinoma, has increase in Mexicans females in the last 20 years.

BACKGROUND: In Mexico, information on oral and pharyngeal cancer (OPC) is scarce. The purpose of this study was to explore the trends in OPC mortality rates in Mexico from 1979 through 2003 and to describe the distribution of OPC deaths for selected socio-demographic variables for the period of 2001-2003. MATERIAL AND METHODS: Annual crude and ageadjusted mortality rates were obtained by gender and site of lesion, using the 2003 WHO World standard million population. The Poisson regression model was used to detect a trend in the mortality rates, testing the hypothesis b 1 = 0. Also, the annual percentage change (APC) was computed over the age-adjusted rates. RESULTS: The total number of OPC deaths during the period 1979-2003 was 15 576. The age-adjusted mortality rate was 1.13 ⁄ 100 000 in 1979 and 1.08 ⁄ 100 000 in 2003. Oral cancer was more frequently found than salivary gland and pharyngeal cancer (41.5% vs. 13.4% and 17.1%). The tongue (19%) was the most frequent oral affected site. The Poisson regression analysis indicated a stationary trend in cancer mortality rate; also, the APC regression model showed no increase or decrease in OPC from 1979 to 2003. CONCLUSIONS: Oral and pharyngeal cancer mortality rates in Mexico were low compared to most countries, and remained stable in the past two decades.
