Objectives To understand the current situation of research on environmental pollution and gastric cancer related population at home and abroad, and to provide scientific basis for future research on the precise prevention and control of gastric cancer in China.
Methods Based on the data of the original population study on gastric cancer and environmental pollution cited by SCI and CNKI from 1989 to 2018, BibExcel, VosViewer, R and other analytical tools were used to analyze the temporal distribution, regional distribution, disciplinary distribution, institutional cooperation and keyword co-occurrence of Chinese and English literatures.
Results In the past 30 years, the number of research papers in Chinese on environmental pollution and gastric cancer was relatively higher from 1995 to 2003, and declined significantly since 2000. In recent years, it maintained a low-number output trend. The number of SCI papers has generally increased. The countries with the largest output of SCI literature are the United States and China. Of literatures published in Chinese, most of the studies carried out in Jiangxi Province. More than 50% of SCI literatures in this field are concentrated in environmental sciences and ecology, and mainly focus on public, environment and occupational health. The hotspots that were focused by Chinese papers including soil trace elements and pollutants, water pollution and gastric cancer. Arsenic, nitrate and metal pollution are the main research issues. The specific pollutants of concern in Chinese and English articles are not in complete accord.
Conclusions The interdisciplinary cooperation and communication between domestic and foreign research institutions should be strengthened for the future research on environmental pollution and gastric cancer in China. In addition to inorganic pollutions, the exposure of organic pollutants should also be fully considered.
