H. pylori, smoking trends, and gastric cancer in U.S. men

  • Posted: May 22, 2013

Trends in Helicobacter pylori (H. pylori) and smoking explain a significant proportion of the decline of intestinal-type noncardia gastric adenocarcinoma (NCGA) incidence in U.S. men between 1978 and 2008, and are estimated to continue to contribute to further declines between 2008 and 2040. These are the conclusions of a study from the Center for Health Decision Science at the Harvard School of Public Health (an affiliate of the Dana-Farber Cancer Institute) in Boston, published in PLOS Medicine, that suggest H. pylori and smoking trends together accounted for almost half of the observed decline in intestinal-type NCGA between 1978 and 2008.

NCI comprehensive cancer centers logoAmong the research institutions NCI funds across the United States, it currently designates 67 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
