Oral cavity cancer incidence and mortality in China, 2010

Introduction: Lip and oral cavity cancer is one of the most prevalent cancers in Asia and considered to be a major public health problem due to the low survival rate. Because of the importance of access to information about this cancer (including incidence, mortality rate and relation to socioeconomic indicators), this study aims at investigating the incidence and mortality of lip and oral cavity cancer and its relationship with the Human Development Index (HDI) of Asia (from 2012). Method: This study was an ecological study in Asia for assessment of the correlation between age-specific incidence rate (ASIR) and age-specific mortality rate (ASMR) with the HDI and its components which include: life expectancy at birth, mean years of schooling and gross national income (GNI) per capita. Data on the standardized incidence ratio (SIR) and the standardized mortality ratio (SMR) for every Asian country for the year 2012 were obtained from the global cancer project and data on the HDI and its components were extracted from the World bank site. We used a bivariate method for assessment of the correlation between the SIR and SMR with the HDI and its individual components. Statistical significance was assumed if P<0.05. All reported P-values were two-sided. Statistical analyses were performed using SPSS (Version 15.0, SPSS Inc.). Results: A total incidence of 162,506 cases and 95,005 deaths were recorded in Asian countries in 2012. Countries with the highest SIR (per 100,000) were the following: Maldives (11), Sri Lanka (10.3), Pakistan (9.8), Bangladesh (9.4), and India (7.2). The highest SMR was observed in the following countries: Pakistan (5.9), Bangladesh (5.6), Afghanistan (5.1), India (4.9), and Maldives (4.1). The correlation between SIR of lip and oral cavity cancer and HDI was -0.378 (p=0.010), with life expectancy at birth at -0.324 (p=0.028), mean years of schooling at -0.283 (p=0.057), and level of income per each person of the population at -0.279 (p=0.060). Moreover, the correlation was -0.664 (p≤0.001) between SMR and HDI. Conclusion: A significant reverse correlation was seen between the incidence and mortality rate of lip and oral cavity cancer and the HDI in Asia. The incidence and mortality of this type of cancer was high in developing or less developed countries.

Relevance: According to GLOBOCAN data for 2020, oral and pharyngeal cancer ranked 25th in mortality (98 412 cases, 0.5% of all cancer deaths) and 26th in the number of diagnosed new cases (48 143 cases, 0.5% of all new cancer cases) in the world. Oral and pharyngeal cancer incidence is growing steadily globally and in the Republic of Uzbekistan. Oral and pharyngeal cancer ranks 16th in the structure of cancer incidence in the Republic of Uzbekistan, with a rate of 1.8 per 100 000 people. The purpose of the study was to analyze the main statistical indicators for tumors of the oral cavity and pharynx in the Republic of Uzbekistan in 2015-2021. Methods: We analyzed the main statistical indicators for tumors of the oral cavity and pharynx in the Republic of Uzbekistan for 2015- 2020 obtained from the Reporting Form #7 “Information about malignant neoplasms cases.” Results: Over the past six years, the incidence rate per 100,000 people has increased from 1.4 in 2015 to 1.8 in 2020. In 2015-2020, in the Republic of Uzbekistan, 2,240 patients died from malignant neoplasms of the oral cavity and pharynx. The mortality rate per 100,000 people decreased from 1.4 in 2015 to 1.2 in 2020. Conclusions: Tumors of the oral cavity and pharynx rank 16th in the structure of cancer incidence in the Republic of Uzbekistan and tend to grow. A recent increase in oral and pharyngeal cancer incidence and its late detection could be explained by worsening detection and diagnostics. The stabilization of oral and pharyngeal cancer mortality results in socio-economic losses for the Republic. The provided statistical data is the basis for improving the indicators of incidence and mortality related to oral and pharyngeal cancer in the Republic of Uzbekistan
