[Disease burden of stomach cancer in the Chinese population, in 1990 and 2013]

Abstract

Objective: To analyze the national and provincial disease burden on stomach cancer in the Chinese population, in 1990 and 2013.

Methods: Data related to province-specific burden of disease in China was used to analyze the standardized incidence and mortality of stomach cancer in 2013. Parameters as incidence, mortality, disability-adjusted life years (DALY), years of life lost due to premature mortality (YLL) and years lived with disability (YLD) on stomach cancer in China in 1990 and 2013, were analyzed while the standardized incidence and mortality of stomach cancer in 1990 and 2013 and the changing patterns in each province were described.

Results: In 2013, there were 371 100 new cases of stomach cancer and 317 800 cases died from stomach cancer in China. Figures on the standardized incidence (26.84/100 000), mortality rate (23.55/100 000) and DALY rate (464.47/100 000) all increased with age. Between 1990 and 2013, the standardized incidence rates in men were all higher than that in women (2.03-2.67 times) but both showed a decreasing trend. Under the reported figures, 317 800 people died from stomach cancer in 2013, with an increase of 13.15%. The number of deaths was 182 700, in 1990. From 1990 to 2013, the standardized mortality rate, DALY and DALY rate decreased in both genders,with more seen in women than in men. The top three provinces that having the highest stomach cancer standardized incidences and mortality in 2013 were Qinghai, Anhui, Gansu. The top three provinces with the most reduction of figures appeared in Tianjin, Shanghai and Zhejiang. Compared with those in 1990, the standardized mortality decreased in all the provinces, in 2013.

Conclusions: The disease burden of stomach cancer in China remained at high level in 2013. Compared with those in 1990, the disease burden of stomach cancer decreased in 2013. The standardized mortality of stomach cancer in all the provinces had decreased but the provincial differences still existed.
