Abstract:
OBJECTIVETo analyze the distribution characteristics and trend of ovary cancer mortality based on results of the Third National Retrospective Sampling Survey of Death Causes.
METHODSData of National Retrospective Sampling Survey for the years of 2004 - 2005 from 158 counties/cities/districts was used for the settings. A total of 69,690,241 person-year for female between 2004 and 2005 including 23,598,822 person-year in urban and 46,091,419 person-year in rural were respectively included in the study. Furthermore, the areas of east, middle, and west were divided into the subsets. And also the areas of urban and rural areas were divided into the subsets. The crude death rate and age-specific death rate and the age-standardized death rate by Chinese population of 1982 (CASR) and by world population of 1960 (WASR) were calculated. The historical comparison with the sampling survey of 1990 - 1992 (second time) was conducted, and the global comparison with some selected countries was performed.
RESULTSThe crude death rate for ovary cancer was 1.45/100 000 (1008/69 690 241) between 2004 and 2005, which was ranked the 12th and accounted for 1.45% (1008/69 667) of all sites of cancers. The CASR was 0.97/100 000 and the WASR was 1.26/100 000. The crude death rate of ovary cancer were 2.67/100 000 (630/23 598 822) and 0.82/100 000 (378/46 091 419) in urban and rural areas respectively, with the CASR of 1.62/100 000 and 0.59/100 000 in urban and rural areas respectively. Compared with the data from the second time (0.06/100 000 for crude death rate, 0.53/100 000 for CASR and 0.75% for proportion), the crude death rate increased by 141.07% and the CASR increased by 83.02%. The proportion of mortality was increased by 92.92%, which ranked from the 17th to the 12th. In the urban areas, the CASR of ovary cancer increased by 31.71% (1.23/100 000 vs 1.62/100 000), while by 118.52% in rural areas (0.27/100 000 vs 0.59/100 000) with an increasing trend more remarkable in rural than in urban.
CONCLUSIONOvary cancer is not the leading site of cancer death-cause in China, its morality is higher in urban than in rural. It is necessary to pay more attention to ovary cancer in China.
