's general knowledge of epidemiology of gastric carcinoma
Gastric carcinoma is one of the main malignant tumour of our country. According to the intersection of our country and 29 provinces and cities, autonomous region ' 1973- 1975) The investigation result of the cause of the death, it accounts for second and the third in man and women death reason to die of malignant tumour. Gastric carcinoma takes the first place in malignant tumour. Annual death is about 160,000 people, accounts for 23.03% of the death of malignant tumour. Of our country gastric carcinoma crude mortality 17.30/10 Wan (man 22.15/10 Wan, woman 12.23/10 Wan) ; The intersection of China and population regulate mortality into 15.41/10 Wan (man 20.93/10 Wan, woman 10.16/10 Wan) ; World population regulate mortality into 23.86/10 Wan, woman 15.93/10 Wan. Belong to the height of gastric carcinoma to send to the country.
The area of gastric carcinoma is distributed gastric carcinoma in different countries of the world, all the difference exists greatly in morbidity and mortality of different areas in the same country.
1.Morbidity
According to " cancer morbidity in the world five continents " of 1982 Materials of Vol. 4. Pluck the morbidity of gastric carcinoma of countries all over the world out, see Table 1. It is the result that cancers from all parts of the world were registered around 1975. Israel most high Japan have, man exceed 70/10 Wan, woman exceed 30/10 Wan. Male morbidity exceed 30/10 area of Wan in Europe, the intersection of Asia and Northeast, Latin America; The morbidity is in 15- 30/10 there are North America, western Europe, the Atlantic Ocean in Wan's areas; And West Asia, Africa, middle and southern American west and Australia are in 15/ 10 Wan is following. The geographical distribution of women's morbidity is generally the same with man. China morbidity, according to Shanghai, man 55.7/10 Wan, woman 21.0/ 10 Wan.
2.Mortality
The country of gastric carcinoma with higher mortality, the main fact is distributed in areas such as Asia, Latin America and Europe,etc.. Japan, Singapore and China, it is the country with higher mortality of Asia. The mortality of Costa Rica, Chile of Latin America Israel is the highest. Countries such as Soviet Union, Hungary, Poland, Iceland, Malia Luo, Bulgaria,etc. had relatively high mortality in the past in Europe. Mortality of the above national male adjustment is in 20/ 10 above Wan. The intersection of gastric carcinoma and the intersection of mortality and low country, male gastric carcinoma adjust mortality in 9/ 10 having U.S.A., Canada, Cuba, Australia, Denmark country following Wan.
According to malignant tumour death in 1973- 1975 of our country's investigation, gastric carcinoma of our country is widespread, the difference of mortality in every area is obvious, and there is relative centralization tendency of geography. The high mortality area is in the Northwest, for instance Qinghai, Ningxia, Gansu, higher mortality is in Jiangsu, Shanghai, Fujian, Zhejiang of Liaoning, Jilin, Heilongjiang and southeast coastal area of the Northeast,etc., the low mortality area is in provinces such as Sichuan, Yunnan, Guizhou, Guangdong and Guangxi,etc.. Count the intersection of mortality and most high Qinghai with province, regulate mortality into 52.63/10 Wan (men) With 27.80/10 Wan (woman) ,Most low Guangxi, 7.02/10 Wan (men) With 3.41/10 Wan (woman) ,Differ by 7.5 times and 8.2 times (see Table 3) in two places . Israel county's share is counted, there are 73 high mortality counties in the whole country, are distributed in 14 provinces, count 10 Gansu, Qinghai, Ningxia, 7 respectively of Anhui, 9 Shanxi, 12 Jiangsu, 6 Fujian, Shaanxi, Henan, the intersection of Zhejiang and 1 respectively, Fujian Changle 3 county 120.47/10 Wan, high to rank first. Low copy, county of mortality, have 98, distribute in 9 province, count 25 of Yunnan, 19 of Guangdong, 14 Guangxi, 10 respectively of Hunan, Sichuan, 8 Guizhou, 5 Jiangxi, 4 Shandong, 2 Hubei, Jiangxi Chongyi county 0.22/10 Wan only, the whole country is the lowest.
