Stomach (C16)
In 2016, stomach cancer cases accounted for 14.33% of all cancer cases in Henan cancer registration areas with the crude incidence of 38.44/105, ASR for China 29.54/105 and ASR for World 29.73/105.The incidence in males was 52.58/105, and 23.4/105 in females.It was 2.51 times in males as high as that in females and it was 1.73 times in rural areas as that in urban areas.The crude mortality rate of stomach cancer in 2016 was 27.72/105, ASR for China was 20.87/105 and ASR for World 20.96/105.The mortality in males was 36.90/105, and 17.97/105 in females.The cumulative rates of incidence and mortality from 0 to 74 years old were 3.74% and 2.46%, respectively.(Table 5-4)

胃恶性肿瘤年龄别发病率和死亡率在0~44岁年龄段处于较低水平，45 岁以后快速上升，在80~岁或85+岁组达到高峰，男性高于女性。城乡和不同地区年龄别率的水平虽然有一定的差异，但总体趋势类同。（图5-4a ～图5-4f）
The age-specific incidence and mortality rates of stomach cancer were relatively low before 45 years old and increased dramatically since 45 years old, reaching the peak at the age group of 80~or 85+.Incidence and mortality rates in males were generally higher than those in females.The age-specific incidence and mortality rates varied in urban and rural areas with similar curves.（Figure 5-4a~figure 5-4f）
