TLDR
The epidemiology, screening, and prevention of gastric cancer are reviewed, including its incidence, survival, mortality, and trends over time, and risk factors are characterized, both environmental and genetic.
Abstract
Less than a century ago, gastric cancer (GC) was the most common cancer in the United States and perhaps throughout the world. Despite its worldwide decline in incidence over the past century, GC remains a major killer across the globe. This article reviews the epidemiology, screening, and prevention of gastric cancer. We first discuss the descriptive epidemiology of GC, including its incidence, survival, and mortality, including trends over time. Next, we characterize the risk factors for gastric cancer, both environmental and genetic. Serological markers and histological precursor lesions of GC and early detection of GC of using these markers is reviewed. Finally, we discuss prevention strategies and provide suggestions for further research.

Global Cancer Incidence and Mortality Rates and Trends—An Update

TL;DR: Applied cancer control measures are needed to reduce rates in HICs and arrest the growing burden in LMICs, as well as for lung, colorectal, breast, and prostate cancer, although some low- and middle-income countries (LMIC) now count among those with the highest rates.

Proportion and number of cancer cases and deaths attributable to potentially modifiable risk factors in the United States

TL;DR: These results may underestimate the overall proportion of cancers attributable to modifiable factors, because the impact of all established risk factors could not be quantified, and many likely modifiable risk factors are not yet firmly established as causal.

Epidemiology of gastric cancer: global trends, risk factors and prevention

TL;DR: Diet, smoking cessation, and exercise hold promise in preventing gastric cancer, while genetic testing is enabling earlier diagnosis and thus greater survival, and a better understanding of the etiology and risk factors of the disease can help reach a consensus in approaching H. pylori infection.

Cancer statistics for African Americans, 2016: Progress and opportunities in reducing racial disparities

TL;DR: Although blacks continue to have higher cancer death rates than whites, the disparity has narrowed and the racial gap in death rates has widened for all cancers combined in men and women and for lung and prostate cancers in men.

Burden of Gastric Cancer.

TL;DR: This article discusses the descriptive epidemiology of gastric cancer, including its incidence, mortality, survival, and secular trends, and combines a synthesis of published studies with an analysis of data from the International Agency for Research on Cancer (IARC) GLOBOCAN project to describe the global burden.

Estimates of worldwide burden of cancer in 2008: GLOBOCAN 2008.

TL;DR: The results for 20 world regions are presented, summarizing the global patterns for the eight most common cancers, and striking differences in the patterns of cancer from region to region are observed.

IARC Monographs on the Evaluation of Carcinogenic Risks to Humans

TL;DR: This timely monograph is a distillation of knowledge of hepatitis B, C and D, based on a review of 1000 studies by a small group of scientists, and it is concluded that hepatitis D virus cannot be classified as a human carcinogen.

Cancer statistics, 2014

TL;DR: The magnitude of the decline in cancer death rates from 1991 to 2010 varies substantially by age, race, and sex, ranging from no decline among white women aged 80 years and older to a 55% decline among black men aged 40 years to 49 years.
