Different trends in stomach and pancreatic cancer mortality rates

Abstract

Not so long ago stomach cancer used to be the most frequent digestive cancer in both sexes in Spain and other Western countries. However, due to the decreasing trend of this disease over the last few decades, gastric cancer ranks seventh and eighth in Spanish women and men, respectively, as a cancer-related cause of death, while being the fourth most frequent digestive cancer, after colorectal, pancreatic and liver cancer. On the other hand, pancreatic cancer mortality figures have been continually increasing, and nowadays this malignancy ranks second among digestive cancers in terms of mortality in both sexes. The distinct trends of stomach and pancreatic cancer mortality rates might be explained by changes in exposure to risk factors, mainly to H. pylori eradication. Notably, these tumors share several modifiable risk factors, such as tobacco consumption, obesity, and physical inactivity. Since these risk factors are also associated with many other cancers, effective cancer prevention strategies are needed to reduce the risk of developing cancer in the population.
