Abstract Background Gastrointestinal (GI) cancer remains a major global health challenge. This study provides updated 2022 estimates of GI cancer incidence and mortality worldwide, along with projections of incident cases and deaths through 2050 to inform cancer control strategies. Methods In this population‐based study, data from the GLOBOCAN 2022 database were used to examine incidence and deaths associated with GI cancer. By using global demographic projections, this study estimated the projected number of incident cases and deaths until the year 2050. Results By 2050, the global burden of GI cancer is projected to reach 9.06 million incident cases (+85%) and 6.42 million deaths (+93%) from 2022. Increases in incidence are projected for both females (+87%) and males (+83%), as are increases in mortality for both females (+97%) and males (+91%). Whereas the Western Pacific region will have the highest absolute burden, with 3.88 million new cases and 2.79 million deaths, the greatest relative increase is expected in Africa, with incidence and deaths rising by 157% and 160%, respectively. As measured by the Human Development Index (HDI), the steepest increases are projected in low (+151% incidence; +152% deaths) and medium (+112% incidence; +114% deaths) HDI countries. Overall, all GI cancer types are projected to increase, led by pancreatic cancer in incidence (+95%) and colorectal cancer in deaths (+103%). Conclusions GI cancer incidence and deaths are expected to nearly double by 2050, with increases across sexes, cancer types, and regions, especially in lower HDI countries.

Backgrounds and Aims: HBV-related liver disease ranks as the seventh leading cause of mortality. Despite advances in prevention and treatment, global disparities in the burden of primary liver cancer (PLC) persist. We evaluate global trends in the prevalence, incidence, and death of HBV-related liver disease. Approach and Results: Data from the Global Burden of Disease Study 2021 evaluated acute HBV infection, HBV-related cirrhosis, and HBV-related liver cancer prevalence, incidence, and death. In 2021, there were 7.30 million cases of acute HBV, 283.64 million cases of HBV-related cirrhosis, and 288,110 cases of HBV-related PLC. HBV-related PLC accounted for 39% of the global incidence of PLC; Western Pacific had the highest rates for HBV-related PLC, with an incidence of 5.24 and a death rate of 4.38 per 100,000 population. Between 2000 and 2021, age-standardized incidence, prevalence, and death rates from HBV-related liver disease decreased; however, the incidence of HBV-related PLC rose in 65 countries from 2000 to 2021. In parallel, age-standardized prevalent rates from HBV-related PLC increased in Europe (annual percent change: 0.77%, 95% CI: 0.72%–0.81%) and the Americas (annual percent change: 1.05%, 95% CI: 1.00%–1.10%). Conclusions: From 2000 to 2021, decreases in HBV-related liver disease incidence and prevalence were observed; however, more than one-third of countries showed an increase in the incidence of HBV-related PLC. These findings highlight the need for strengthened HBV treatment efforts to reduce the risk of liver cancer.

INTRODUCTION: To update the global burden of inflammatory bowel disease (IBD) using data from the Global Burden of Disease 2021. METHODS: Data from Global Burden of Disease 2021 were analyzed to assess the IBD burden. RESULTS: In 2021, there were 375,140 new cases and 3.83 million total cases of IBD. Elderly onset IBD accounted for 11% of incidences. 167 countries increased IBD incidence rate, with rates rising in female patients (APC: +0.06%) and the elderly (APC: +0.14%) but stable in male patients and the overall population. DISCUSSION: Although the global burden of IBD has decreased overall, it has increased in female patients and the elderly.

Background Gastrointestinal cancers comprise nearly one-third of global mortality from cancer, yet the comprehensive global burden of these cancers remains uninvestigated. Objective We aimed to assess the global, regional and national burden of gastrointestinal cancers. Designs Data on oesophagus, gastric, colorectal, liver, pancreas and biliary tract cancers were extracted from the Global Burden of Disease 2021 database. Age-standardised incidence rate (ASIR) and age-standardised death rate (ASDR) were calculated by sex, region and Sociodemographic Index (SDI). Results In 2021, there were 5.26 million incidences and 3.70 million deaths from gastrointestinal cancer. The greatest burden is from colorectal, followed by gastric, oesophageal, pancreatic, liver and biliary tract cancer. We noted geographical and socioeconomic differences in ASIR and ASDR across all types of cancers. From 2000 to 2021, ASIR increased for colorectal cancer (annual percent change (APC): 0.10%, 95% CI 0.05% to 0.14%), pancreatic cancer (APC: 0.27%, 95% CI 0.14% to 0.41%), and liver cancer from metabolic dysfunction-associated steatotic liver disease (APC: 0.62%, 95% CI 0.58% to 0.67%) and alcohol-related liver disease (APC: 0.26%, 95% CI 0.22% to 0.30%). ASDR increased for pancreatic cancer (APC: 0.18%, 95% CI 0.02% to 0.34%). Higher SDI countries had higher incidence rates for most types of gastrointestinal cancer. Conclusions Although the ASIR of oesophageal, gastric and biliary tract cancer has decreased, the ASIR still increased in colorectal, pancreatic and liver cancer from steatotic liver disease. Public policies are important for controlling gastrointestinal cancers—most importantly, reducing alcohol consumption, hepatitis B immunisation and tackling the burden of metabolic diseases.
