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.
背景。中国老年人口一直在增加，但该人群癌症的模式和趋势鲜有报道。方法。估计了2004年至2005年中国全体人群和老年人群所有部位及特定部位癌症的死亡率。利用中国全国死亡调查、疾病监测点和癌症登记处的数据，采用世界人口年龄结构来观察1975年至2005年年龄标准化死亡率的变化。结果。中国老年人的死亡率为每10万人782.12例，显著高于60岁以下人群。老年人群中肺癌、胃癌、肝癌和食管癌的死亡率与较年轻年龄组相比有大幅上升。在老年人中，胃癌是仅次于肺癌的第二大常见癌症，这两种恶性肿瘤在老年男性中的死亡率相似，而在老年女性中，胃癌排名第一，超过了肺癌。在所有年龄组中均观察到癌症的M/I比值呈持续下降趋势。结论。在中国老年人中应高度重视并大力实施癌症预防策略和具有成本效益的预防干预措施。
