Abstract

The overall mortality rates of stomach cancer in the past 20 years in China presented an increasing trend, despite there were upward and downward changes in 27 provinces and decrease in cities while increase in rural areas. Compared with other countries, the world-adjusted mortality rate of stomach cancer for both sexes in China ranks first. The increasing trend in stomach cancer mortality was seen in the older age groups (> 60 years) while a decreasing trend was seen in the younger age groups (30 - 59 years). Aging of the population could be an important factor responsible for the increase in mortality rates of stomach cancer in China.
