title: Epidemiological characteristics of cancer in elderly chinese.
abstract: Background. Population of elder Chinese has been increasing, but the pattern and trend of cancer in that population was rarely reported. Methods. Mortality rates for cancer of all sites and of the site specific of the overall and elderly Chinese from 2004 to 2005 were estimated. The age structure of world population was used to observe the changes in the age-standardized mortality rates from 1975 to 2005 using the data from the national death surveys, Disease Surveillance Points, and cancer registries in China. Results. The mortalities among the elderly Chinese were 782.12 per 100,000, substantially higher than those of the people less than 60 years old. The mortalities for cancers of lung, stomach, liver, and esophagus in elderly population showed great increase compared to younger ages. Stomach cancer ranked as the second most common cancer following lung cancer in the elderly, and those two malignancies had similar mortality rates in male elderly, while in female, it ranked as first, surpassed lung cancer. Consistent decreased trends of M/I ratios of cancer were observed in all age groups. Conclusion. Strategies in cancer prevention and cost-effective preventive intervention should be highly considered and strongly implemented among the elderly Chinese.
