[Analysis of cancer incidence and mortality in elderly population in China, 2013].

Objective: To estimate the cancer incidence and mortality in elderly Chinese population in 2013 based on the data from local cancer registries submitted to National Central Cancer Registry (NCCR). Methods: Data from 255 cancer registries submitted to NCCR with qualified data after checked and evaluated, were selected for this estimation. Cancer incidence and mortality were stratified by areas, sex, age groups and cancer site, combined with population data of the year 2013 to estimate cancer epidemiology in older people in China. Chinese population census in 2000 and Segi's population were used for the estimation of age-standardized incidence/mortality rates. Results: All the 255 cancer registries (88 in urban and 167 in rural areas) were selected for this estimation, covered 37 407 728 elderly subjects, accounting for 17.73% of the entire national elderly population. It was estimated about 2 171.0 thousand new cancer cases in older people in China, accounting for 58.96% of all cancer incidence, with the crude incidence rate of 1 029.16/100 000 (1 297.96 per 100 000 in male, 777.18 per 100 000 in female), and the age-standardized incidence rate by Chinese standard population (ASIRC, 2000) was 1 019.25 per 100 000. It was estimated about 1 600.5 thousand deaths in older people in China, accounting for 67.70% of all cancer deaths, with the crude mortality of 758.72/100 000 (988.37 per 100 000 in males, 543.44 per 100 000 in females), and the age-standardized incidence rate by Chinese standard population (ASIRC, 2000) was 730.78 per 100 000. Lung cancer, stomach cancer, colorectal cancer, liver cancer and esophageal cancer were the most common cancers, accounting for about 67.70% of all cancer cases in China. Those cancers are also the most common cancers in China, accounting for about 73.45% of all cancer deaths. Conclusions: The cancer burden of elderly population in China is very serious. The major cancer incidence and mortality in urban and rural areas are similar, but the cancer patterns are very different in urban and rural areas. As cancer burdens for older people are different between urban and rural areas in China, more attention should be paid to the need of older people according to the actual situation.目的： 根据全国肿瘤登记中心收集的全国各肿瘤登记处的登记资料，估计全国2013年中国老年人群恶性肿瘤的发病和死亡情况。 方法： 选取2013年全国上报的质量符合数据质量控制要求的255个登记处(其中地级以上城市88个，县和县级市168个)的肿瘤登记数据，结合2013年全国人口数据，估计全国2013年老年人群(≥60岁)恶性肿瘤的发病和死亡情况。中国人口标化率(简称中标率)采用2000年全国普查的标准人口年龄构成，世界人口标化率(简称世标率)采用Segi′s世界标准人口年龄构成。 结果： 255个登记处共覆盖中老年人口37 407 728人，占全国老年人口的17.73%。估计全国2013年老年人群恶性肿瘤新发病例约217.10万例，占全人群恶性肿瘤的58.96%，发病率为1 029.16/10万(男性1 297.96/10万，女性777.18/10万)，中标率为1 019.25/10万。老年人群恶性肿瘤死亡约160.05万例，死亡率为758.72/10万(男性988.37/10万，女性543.44/10万)，中标率为730.78/10万，占全人群恶性肿瘤死亡的71.80%。肺癌、胃癌、结直肠癌、肝癌和食管癌是我国老年人群主要的常见恶性肿瘤，约占老年人群恶性肿瘤新发病例的67.70%；同时，肺癌、肝癌、胃癌、食管癌和结直肠癌也是我国老年人群主要的肿瘤死因，约占全部肿瘤死亡病例的73.45%。 结论： 我国老年人群恶性肿瘤负担较大，城乡地区的老年人群的主要肿瘤发病死亡癌种相似，但癌谱构成及顺位差异明显，应加强老年人群恶性肿瘤防控，并根据实际情况有针对性地开展老年人群防治工作。.
