Global trends in esophageal cancer mortality with predictions to 2025, and in incidence by histotype

Esophageal cancer (EC) is a malignancy with a poor prognosis. We provided a global overview of EC mortality, analyzing figures over the last three decades and estimating mortality rates for the year 2025. We also reported incidence trends and the distribution of squamous cell carcinoma (SCC) and adenocarcinoma (AC) in selected countries. We considered EC trends in the age-standardised mortality rates (ASMR) from the World Health Organization database for selected countries. To estimate the number of deaths and ASMRs for 2025, we applied a Poisson linear regression model to the latest trend segment identified using a joinpoint model. We reported EC incidence trends according to histology using the Cancer Incidence in Five Continents database for the calendar period of 1990–2012. In 2015–19, the male ASMRs/100,000 were 4.01 in the EU-27, 4.28 in the USA, and 5.10 in Japan. The corresponding female rates ranged from 0.82 to 0.85/100,000. Male mortality showed a decreasing trend in most countries analyzed, with earlier and steeper declines in southern Europe. Conversely, ASMRs were increasing in Belarus, Finland, Greece, and Cuba. Female mortality showed a slight increase in several European countries, while North America, Latin America, and Australasia showed favorable trends. Projections suggest that male EC mortality is expected to decline in all countries except the Russian Federation. Female favorable trends are also predicted in most countries, except for France, Germany, the Russian Federation, and Canada. SCC remained the most common histotype, but AC incidence showed an upward trend, particularly in high-income countries. The observed trends in EC mortality reflect variations in patterns of major risk factors. Effective control of risk factors would contribute to reducing the burden of EC, together with early diagnosis and potential improvements in treatments.
