The article offers information on a study which analyzed patterns and trends in childhood cancer mortality in 24 developed and middle-income countries in America, Asia and Oceania between 1970 and 2007. A review of the related literature on childhood cancer mortality is offered. Data reviewed were from the World Health Organization (WHO) database for all neoplasms, bone and kidney cancer, non-Hodgkin lymphoma (NHL) and leukemias. The findings of the study are presented in detail.

Introduction: We estimated cancer mortality figures in five major Asian countries and Australia for 2024, focusing on stomach cancer, a leading cause of cancer-related deaths in Eastern Asia., Methods: We computed country- and sex-specific annual age-standardized rates (ASRs) for total cancers and the 10 most common cancer sites, using WHO and the United Nations Population Division databases from 1970 to 2021 or the latest available year. We predicted figures for 2024 and estimated the number of avoided cancer deaths in 1994-2024., Results: All cancers combined ASR declined between 2015-2019 and 2024 across considered countries and sexes. In 2024, the lowest predicted male rate is in the Philippines (75.0/100 000) and the highest in Australia (94.2/100 000). The Republic of Korea is predicted to have the lowest female ASR (42.1/100 000) while the Philippines the highest (74.5/100 000). Over the last three decades, 121 300 deaths were estimated to be avoided in Hong Kong SAR, 69 500 in Israel, 1 246 300 in Japan, 653 300 in the Republic of Korea, 303 300 in Australia, and 89 700 among Philippine men. Mortality from stomach cancer has been decreasing since 1970 in all considered countries and both sexes. Significant decreases are at all age groups Male rates remain, however, high in Japan (8.7/100 000) and the Republic of Korea (6.2/100 000)., Conclusion: Declining cancer mortality is predicted in the considered countries, notably reducing stomach cancer burden. Stomach cancer, however, remains a major public health issue in East Asia., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

Gastric cancer incidence and mortality decreased substantially over the last decades in most countries worldwide, with differences in the trends and distribution of the main topographies across regions. To monitor recent mortality trends (1980-2011) and to compute short-term predictions (2015) of gastric cancer mortality in selected countries worldwide, we analysed mortality data provided by the World Health Organization. We also analysed incidence of cardia and non-cardia cancers using data from Cancer Incidence in Five Continents (2003-2007). The joinpoint regression over the most recent calendar periods gave estimated annual percent changes (EAPC) around -3% for the European Union (EU) and major European countries, as well as in Japan and Korea, and around -2% in North America and major Latin American countries. In the United States of America (USA), EU and other major countries worldwide, the EAPC, however, were lower than in previous years. The predictions for 2015 show that a levelling off of rates is expected in the USA and a few other countries. The relative contribution of cardia and non-cardia gastric cancers to the overall number of cases varies widely, with a generally higher proportion of cardia cancers in countries with lower gastric cancer incidence and mortality rates (e.g. the USA, Canada and Denmark). Despite the favourable mortality trends worldwide, in some countries the declines are becoming less marked. There still is the need to control Helicobacter pylori infection and other risk factors, as well as to improve diagnosis and management, to further reduce the burden of gastric cancer., (Copyright © 2014 Elsevier Ltd.

Until the mid-1990s, gastric cancer has been the first cause of cancer death worldwide, although rates had been declining for several decades and gastric cancer has become a relatively rare cancer in North America and in most Northern and Western Europe, but not in Eastern Europe, Russia and selected areas of Central and South America or East Asia. We analyzed gastric cancer mortality in Europe and other areas of the world from 1980 to 2005 using joinpoint regression analysis, and provided updated site-specific incidence rates from 51 selected registries. Over the last decade, the annual percent change (APC) in mortality rate was around -3, -4% for the major European countries. The APC were similar for the Republic of Korea (APC = -4.3%), Australia (-3.7%), the USA (-3.6%), Japan (-3.5%), Ukraine (-3%) and the Russian Federation (-2.8%). In Latin America, the decline was less marked, but constant with APC around -1.6% in Chile and Brazil, -2.3% in Argentina and Mexico and -2.6% in Colombia. Cancers in the fundus and pylorus are more common in high incidence and mortality areas and have been declining more than cardia gastric cancer. Steady downward trends persist in gastric cancer mortality worldwide even in middle aged population, and hence further appreciable declines are likely in the near future.

Background/aims: Cirrhosis mortality has registered large changes over the last few decades., Methods: Age-standardized (world standard) cirrhosis mortality rates per 100,000 were computed for 41 countries worldwide over the period 1980-2002 using data from the WHO mortality database., Results: In the early 1980s, the highest rates were in Mexico, Chile (around 55/100,000 men and over 14/100,000 women), France, Italy, Portugal, Austria, Hungary and Romania (around 30-35/100,000 men and 10-15/100,000 women). Mortality from cirrhosis has been steadily declining in most countries worldwide since the mid or late 1970s (annual percent change, APC, between -5% and -1.5% in the last decade only for both sexes). In southern Europe, rates in the early 2000s were less than halved compared to earlier decades. In contrast, rates have been rising in Eastern European countries to reach extremely high values in the mid 1990s, and declined only thereafter. In the UK rates were still steadily rising (APC around +7% in men and +3% in women from England and Wales, and +9% in men and +7% in women from Scotland)., Conclusions: Mortality from cirrhosis shows favourable trends in most countries of the world, following the reduction in alcohol consumption and hepatitis B and C virus infection. The steady upward trends observed over more recent calendar periods in the UK and central and eastern European countries are attributed to the persistent increase in the prevalence of alcohol consumption.

Objective: To investigate risk factors for medullary thyroid cancer (MTC)., Methods: We conducted a pooled analysis of 14 case-control studies from Europe, North America, and Asia, including 67 medullary cancers (43 women and 24 men) diagnosed in ten studies. Of the original 4776, we selected five controls per case matched on study, gender, and age. The pooled odds ratios (OR) were estimated using conditional logistic regression., Results: Education, weight, and body mass were not associated with MTC, but a significant positive relationship was seen with height (OR = 2.6 for highest vs lowest tertile). Significant excess risks were associated with a history of thyroid nodules (OR = 12), hypertension (OR = 2.3), gallbladder disease (OR = 4.3), and allergies (OR = 2.2). Among current smokers, a decreased risk of MTC was observed with increasing number of cigarettes. The risk was significantly elevated among women having a first birth after age 25 years, but no clear pattern emerged for other reproductive factors., Conclusions: Although the number of MTC was small, we detected several significant associations, including prior thyroid and other diseases.
