AI Article Synopsis
- Gastric cancer is a major health concern in the US, with higher occurrence and death rates, and this study analyzes trends from 2000 to 2020 based on age, sex, histology, and race/ethnicity, as well as the impact of COVID-19.
- Data was collected from the Surveillance, Epidemiology, and End Results 22 program, classifying gastric cancer types and analyzing trends using average annual percent change (AAPC) and age-standardized incidence rates (ASIRs).
- Findings reveal that most gastric cancer cases were in individuals aged 55+, predominantly among men and Non-Hispanic Whites, while COVID-19 caused a significant drop in incidence rates, particularly affecting younger adults and highlighting
Article Abstract
Background: Gastric cancer ranks among the top cancers in terms of both occurrence and death rates in the United States (US). Our objective was to provide the incidence trends of gastric cancer in the US from 2000 to 2020 by age, sex, histology, and race/ethnicity, and to evaluate the effects of the COVID-19 pandemic.
Methods: We obtained data from the Surveillance, Epidemiology, and End Results 22 program. The morphologies of gastric cancer were classified as adenocarcinoma, gastrointestinal stromal tumor, signet ring cell carcinoma, and carcinoid tumor. We used average annual percent change (AAPC) and compared pairs using parallelism and coincidence. The numbers were displayed as both counts and age-standardized incidence rates (ASIRs) per 100000 individuals, along with their corresponding 95% confidence intervals (CIs).
Results: Over 2000-2019, most gastric cancers were among those aged ≥55 years (81.82%), men (60.37%), and Non-Hispanic Whites (62.60%). By histology, adenocarcinoma had the highest incident cases. During the COVID-19 pandemic, there was a remarkable decline in ASIRs of gastric cancer in both sexes and all races (AAPC: -8.92; 95% CI: -11.18 to -6.67). The overall incidence trends of gastric cancer were not parallel, nor identical.
Conclusions: The incidence of gastric cancer shows notable variations by age, race, and sex, with a rising trend across ethnicities. While the overall incidence has declined, a noteworthy increase has been observed among younger adults, particularly young Hispanic women; however, rates decreased significantly in 2020.
