This article presents a global population-based study on the distribution and trends of salivary gland cancer. The study utilized data from the Global Cancer Observatory and the Cancer Incidence in Five Continents Plus. The findings reveal that salivary gland cancer burden is higher in regions with higher Human Development Index (HDI) and is associated with lifestyle factors such as smoking and alcohol consumption. The study also highlights a rising trend of salivary gland cancer among females, possibly linked to hormonal factors. However, the study acknowledges limitations in data availability and classification in low-income countries. Further research is needed to understand the complex relationship between socioeconomic factors and salivary gland cancer burden. [Extracted from the article]

Background: This study aims to investigate the global disease burden, risk factors, and temporal trends of eye cancer by sex and age group. Methods: Databases including Cancer Incidence in Five Continents volumes I–XI, the Nordic Cancer Registries, the Surveillance, Epidemiology, and End Results Program and the WHO IARC mortality database were accessed to extract incidence and mortality data. Joinpoint regression analyses were conducted to evaluate the Average Annual Percentage Change of the incidence and mortality. Results: The age‐standardised rates of eye cancer incidence and mortality were 0.49 and 0.08 globally in 2020. Higher incidence rates were observed in Sub‐Saharan Africa (ASR = 4.06), Western Europe (ASR = 0.89), and Northern Europe (ASR = 0.84), but higher mortality was observed only in Sub‐Saharan Africa (ASR = 1.59). Lower HDI, higher prevalence of UV exposure and lower prevalence of several lifestyle habits and metabolic syndromes were associated with higher incidence and mortality. There was an overall stable incidence trend and a decreasing mortality trend. Notably, all countries reporting decreasing trend in mortality were in the Asian or European region. Conclusions: Although higher incidence was observed in both African and European regions, only the Sub‐Saharan Africa region reported high mortality, indicating inequity in the access of healthcare and treatment resource. Higher prevalence of UV exposure was associated with both higher incidence and mortality. Education should be provided to increase the awareness of eye protection. An overall declining mortality trend was found, but it was limited to only Asian and European countries. [ABSTRACT FROM AUTHOR]

Background: Though the laryngeal cancer only has 1% of the total cancer cases and related deaths, it is a type of head and neck cancers with the highest prevalence. This study aims to investigate the epidemiological trend of laryngeal cancer with updated data on the global distribution of the disease burden. Materials and methods: The incidence and mortality rate of laryngeal cancer was extracted from GLOBOCAN (2020), Cancer Incidence in Five Continents series I-X, WHO mortality database, the Nordic Cancer Registries, and the Surveillance, Epidemiology, and End Results Program. The Global Health data exchanges for the prevalence of its associated risk factors. A Joinpoint regression analysis was used to calculate Average Annual Percentage Change (AAPC). Results: The age-standardised rate (ASR) of laryngeal cancer incidence and mortality were 2.0 and 1.0 per 100 000 worldwide. The Caribbean (ASR=4.0) and Central and Eastern Europe (ASR=3.6) had the highest incidence and mortality rate. Incidence and risk factors associated with laryngeal cancer included tobacco usage, alcohol consumption, poor diet, obesity, diabetes, hypertension, and lipid disorders. There was an overall decreasing trend in incidence, especially for males, but an increasing incidence was observed in female populations and younger subjects. Conclusions: As overall global trends of laryngeal cancer have been decreasing, especially for the male population, this could possibly be attributed to reduced tobacco use and alcohol consumption. Decrease in mortality may be due to improved diagnostic methods and accessibility to treatment, yet disparity in trend remains potentially because of differences in the level of access to surgical care. Disparities in temporal trends across countries may require further research and exploration to determine other underlying factors influencing this. [ABSTRACT FROM AUTHOR]

Vulvar cancer is an uncommon malignancy. Vulvar cancer alarmed the public health problem in terms of the cost of diagnostic and medical treatments and psychical health of females. Our study aims to provide a thorough analysis of the global disease burden, related risk factors and temporal incidence trends of vulvar cancer in population subgroups. Data from Global Cancer Observatory and the Cancer Incidence in Five Continents Plus were used for the vulvar cancer incidence. Age‐standardized rates (ASR) were used to depict the incidence of vulvar cancer. The 10‐year trend of incidence was assessed using joinpoint regression with average annual percentage change and 95% confidence intervals in various age groups, while its correlations with risk factors were investigated using linear regression. Higher ASR were found in Western Europe (2.4), Northern America (1.9), Northern Europe (1.9), Australia and New Zealand (1.8) and Eastern Africa (1.4). The associated risk factors of higher vulvar cancer incidence were gross domestic product per capita, Human Development Index, higher prevalence of smoking, alcohol drinking, unsafe sex and human immunodeficiency virus infection. The overall trend of vulvar cancer incidence was increasing. An increasing trend was found in older females while a mixed trend was observed in younger females. The disease burden of vulvar cancer follows a bimodal pattern according to its two histologic pathways, affecting women in both developed and developing regions. Smoking cessation, sex education and human papillomavirus vaccination programs should be promoted among the general population. Subsequent studies can be done to explore the reasons behind the increasing trend of vulvar cancer. [ABSTRACT FROM AUTHOR]

Background: Lip, oral and pharyngeal cancers make up a small percentage of total cancer cases worldwide and have reported lower rates of cancer‐related deaths globally in 2020, but their 5‐year survival rate in either early or advanced stages is different. The study evaluated the global incidence, mortality, risk factors, and temporal trends by age, gender, and geographical locations of lip, oral cavity, and pharyngeal cancer. Methods: Incidence and mortality rates were extracted from Cancer Incidence in Five Continents (CI5) volumes I‐XI, the Nordic Cancer Registries (NORDCAN), the Surveillance, Epidemiology, and End Results (SEER) Program, and the WHO IARC mortality database. Joinpoint regression was used to calculate the Average Annual Percentage Change to examine trends. Results: The highest incidence rates were found in Melanesia and South‐Central Asia and mortality rates were 8.2 and 7.5. Risk factors associated with incidence and mortality included HDI, tobacco use, alcohol consumption, poor diet, and chronic health conditions such as hypertension. Increasing trends of incidence and mortality were observed in females from Malta; males aged 50 and above from the United Kingdom, and females aged 50 and above from Slovakia reporting the largest increase. Conclusions: Although global incidence and mortality trends reported an overall decrease, significant increases were found for older age groups and female subjects. Incidence increase may be due to the growing prevalence of lifestyle, metabolic risk factors, and HPV infections, especially in developed countries. [ABSTRACT FROM AUTHOR]

Background/Methods: The Cancer Incidence in Five Continents Time Trends, Nordic Cancer Registries, Surveillance, Epidemiology and End Results, WHO Mortality databases were assessed to extract the Age‐Standardised Rates (ASR) of cancer incidence and mortality among children aged 0–14 years old. By using the ASRs, the country‐specific Average Annual Percentage Change (AAPC) and its corresponding 95% confidence interval (CI) were calculated to determine the epidemiological cancer trend. Results: In 2020, the highest incidence of childhood cancer was found in countries with higher Human Development Index (HDI) (ASR = 15.7), yet the highest mortality was found in countries with lower HDIs (ASR = 4.8). As for incidence, seven countries had positive AAPC among boys; Slovakia (AAPC2001–2010 = 4.98, 95% CI [1.66–8.40]), Ecuador (AAPC2003–2012 = 4.07, 95% CI [0.67–7.59]) and Thailand (AAPC2003–2012 = 3.69, 95% CI [0.37–7.11]) had the highest AAPC. Among girls, three countries had positive AAPC, which included Belarus (AAPC2003–2012 = 3.18, 95% CI [1.11, 5.29]), Canada (AAPC2003–2012 = 2.83, 95% CI [1.60, 4.07]) and Korea (AAPC2003–2012 = 1.76, 95% CI [0.23–3.32]). There was an overall decreasing trend of mortality. However, increased mortality was observed in two countries: Ecuador for boys (AAPC2007–2016 = 1.72, 95% CI [0.27–3.19]) and Austria for girls (AAPC2008–2017 = 4.11, 95% CI [0.38–7.98]). Conclusions: The largest mortality and mortality to incidence ratio of childhood cancer were found in low‐income countries. There was a substantial increasing trend of childhood cancer incidence, while overall its mortality has been decreasing over the past decade. More studies are needed to confirm the drivers behind these epidemiologic trends. [ABSTRACT FROM AUTHOR]

Leukaemia accounted for approximately 2.5% of all new cancer incidence and 3.1% of cancer-related mortality. The investigation of its risk factors and epidemiologic trends could help describe the geographical distribution and identify high-risk population groups. This study aimed to evaluate the global incidence, mortality, associated risk factors, and temporal trends of leukaemia by sex, age, and country. We extracted incidence and mortality of leukaemia from GLOBOCAN, CI5, WHO mortality database, NORDCAN, and SEER. We searched the WHO Global Health Observatory data repository for the agestandardised prevalence of lifestyle and metabolic risk factors. We tested the trends by calculating Average Annual Percentage Change (AAPC) from Joinpoint regression. The age-standardized rate of incidence and mortality were 5.4 and 3.3 per 100,000 globally. The incidence and mortality of leukaemia were associated with Human Development Index, Gross Domestics Products per capita, prevalence of smoking, physical activity, overweight, obesity, and hypercholesterolaemia at the country level. Overall, more countries were showing decreasing trends than increasing trends in incidence and mortality. However, an increasing trend of leukaemia incidence was found in Germany, Korea, Japan, Canada and the United Kingdom (AAPC, 2.32-0.98) while its mortality increased in the Philippines, Ecuador, Belarus, and Thailand (AAPC, 2.49-1.23). There was a decreasing trend of leukaemia for the past decade while an increase in incidence and mortality was observed in some populations. More intensive lifestyle modifications should be implemented to control the increasing trends of leukaemia in regions with these trends. Future studies may explore the reasons behind these epidemiological transitions. [ABSTRACT FROM AUTHOR]

Simple Summary: Ovarian cancer was the third most common gynecological cancer globally in 2020. Ovarian carcinoma is the most common type of ovarian cancer, comprising over 90% of all ovarian cancer cases. The risk of ovarian cancer increases in females with age, along with having a family history, having a family cancer syndrome, and breast cancer susceptibility gene (BRCA) mutations. Investigation of the latest disease burden, risk factors, and temporal trends of ovarian cancer is important for the reduction of its associated mortality globally. The global incidence and mortality rates of ovarian cancer for 185 countries in 2020 were retrieved from the Global Cancer Observatory (GLOBOCAN) database established by the International Agency for Research on Cancer (IARC, WHO, Lyon, France). The incidence of ovarian cancer has been increasing substantially among younger females, probably caused by the increasing prevalence of obesity, metabolic syndrome, estrogen exposure and nulliparity. This study aimed to investigate the most updated worldwide incidence and mortality, risk factors, and epidemiologic trend of ovarian cancer in different countries, regions, and age groups. The Global Cancer Observatory database was used for incidence and mortality rates of ovarian cancer in 2020. Data from Cancer Incidence in Five Continents and the WHO mortality database was accessed for trend analysis. Age-standardized rates (ASRs, per 100,000 persons) were calculated for incidence and mortality. The 10-year annual average percent change (AAPC) was estimated by Joinpoint regression analysis. There was an overall decreasing trend of ovarian cancer, yet its burden has been increasing in lower-income countries and among younger females in some countries. Intensive lifestyle modifications are warranted, especially for the populations at high risk for ovarian cancer, including smoking cessation, alcohol use reduction, physical activity, weight control, and treatment of metabolic diseases.

Objective Design Setting Population Methods Main Outcome Measures Results Conclusions This study aimed to investigate the incidence, risk factors and trends for vaginal cancer.Retrospective observational design.Data were collected from multiple sources, including the Global Cancer Observatory, Cancer Incidence in Five Continents Plus, Global Burden of Disease, World Bank and the United Nations.Individuals diagnosed with vaginal cancer.The study collected data on vaginal cancer from the specified sources. The age‐standardised rate (ASR) of vaginal cancer was calculated for different regions and age groups. Multivariable and univariable linear regression analyses were performed to examine the associations between risk factors and the incidence of vaginal cancer. Trend analysis was conducted using joinpoint regression analysis, and the average annual percentage change (AAPC) was calculated to quantify the temporal trend.The main outcome measures of the study were the incidence of vaginal cancer, risk factors associated with the disease and the trend of its incidence over time.There were 17 908 newly reported cases of vaginal cancer (ASR = 0.36, 95% CI 0.30–0.44) in 2020, with the highest ASRs reported in South–Central Asia and Southern Africa. Risk factors associated with a higher incidence of vaginal cancer included a higher prevalence of unsafe sex and human immunodeficiency virus (HIV) infection. The temporal trend showed an overall rising incidence globally, with Iceland (AAPC = 29.56, 95% CI 12.12–49.71), Chile (AAPC = 22.83, 95% CI 13.20–33.27), Bahrain (AAPC = 22.05, 95% CI 10.83–34.40) and the UK (AAPC = 1.40, 95% CI 0.41–2.39) demonstrating the most significant rising trends.The significant regional disparities and risk factors associated with vaginal cancer underscore the necessity for targeted interventions and education, particularly in regions with a lower human development index (HDI) and a higher prevalence of human papillomavirus (HPV) infection. The increasing incidence trend emphasises the need for enhanced HPV vaccination rates to prevent the development of vaginal cancer. [ABSTRACT FROM AUTHOR]
