Gastric cancer mortality rates among US and foreign-born persons: United States 2005–2014

Abstract

Background Historically, foreign-born individuals in the US have had an elevated risk of dying from gastric cancer when compared to US-born individuals. This is primarily due to factors that occur prior to their immigration to the US, including diet and underlying risk of H. pylori infection. Methods National mortality data from 2005 to 2014 were obtained from the CDC's National Center for Health Statistics. Annual population estimates were obtained from the US Census Bureau's American Community Survey for foreign-born and US-born persons. Age-adjusted gastric cancer mortality rates and rate ratios (RR) were calculated stratified by birth place, age, race/ethnicity, and geographic location. Results From 2005 to 2014, 111,718 deaths from malignant gastric cancer occurred in the US, of which 24,583 (22%) occurred among foreign-born individuals. Overall, foreign-born individuals had higher mortality rates compared with USborn individuals (RR 1.82; 95% CI 1.80, 1.85) and this difference remained after stratifying by sex, age, and geographic location. However, this finding was primarily driven by the low rate of gastric cancer mortality among US-born whites, with similar mortality rates observed among all other foreign-born and US-born groups. Gastric cancer mortality rates significantly decreased during the study period overall (AAPC − 2.50; 95% CI − 3.21, − 1.79) with significant declines observed among US-born (AAPC − 2.81; 95% CI − 3.55, − 2.07) and the foreign-born (AAPC − 2.53; 95% CI − 3.20, − 1.86) population. Conclusions Efforts directed at reducing the prevalence of gastric cancer risk factors could help reduce the elevated burden observed among foreign-born individuals and US-born minority groups.

Racial and ethnic disparities in mortality from gastric and esophageal adenocarcinoma

“…While these distinct racial/ethnic incidence patterns in NCGC and CGC are established, few studies have compared differences in survival and mortality trends among racial/ethnic groups in these cancer subtypes. Several studies assessed survival and death certificate mortality in gastric cancer overall, yielding mixed results 6‐13 . Some showed no differences, while others showed higher survival among Asians/Pacific Islanders and inconsistent outcomes in Hispanics 6‐10 …”

Cancer-Specific Survival Analysis in Patients with Gastric Cancer: Based on Competing Risk Model

“…As we know above, this result is relatively stable and reliable. Besides, we have evidence that some studies have shown that the death risk of gastric cancer was highest among Asians/Paci c Islanders, followed by Blacks and was least common in Whites [48,49]. This difference may be due to the higher survival rate of white gastric cancer patients dying from other causes than gastric cancer [10,50], and the difference between white and African Americans can be generalized to the difference between other races and whites.…”

Berberine Attenuates Chronic Atrophic Gastritis Induced by MNNG and Its Potential Mechanism

“…Gastric cancer (GC) is the second leading cause of cancer-related death worldwide ( Hallowell et al, 2019 ; Liou et al, 2020 ). Chronic atrophic gastritis (CAG) is a chronic gastric mucosal inflammation associated with the loss of gastric glandular cells, replaced by intestinal-type epithelium and fibrous tissue ( Tian et al, 2019 ).…”
