BACKGROUND: As populations age, cancer burden becomes increasingly conspicuous. This study quantified the cancer burden of the elderly (≥ 60 years) in China, based on the China Cancer Registry Annual Report to provide epidemiological evidence for cancer prevention and control. METHODS: Data on cancer cases and deaths among the elderly aged ≥ 60 years were collected from the China Cancer Registry Annual Report, 2008-2019. Potential years of life lost (PYLL) and disability-adjusted life years (DALY) were calculated to analyze fatalities and the non-fatal burden. The time trend was analyzed using the Joinpoint model. RESULTS: From 2005 to 2016, the PYLL rate of cancer in the elderly was stable between 45.34‰ and 47.62‰, but the DALY rate for cancer decreased at an average annual rate of 1.18% (95% CI: 0.84-1.52%). The non-fatal cancer burden in the rural elderly was higher than that of the urban elderly. Lung, gastric, liver, esophageal, and colorectal cancers were the main cancers causing the cancer burden in the elderly, and accounted for 74.3% of DALYs. The DALY rate of lung cancer in females in the 60-64 age group increased (annual percentage change [APC] = 1.14%, 95% CI: 0.10-1.82%). Female breast cancer was one of the top five cancers in the 60-64 age group, with DALY rates that also increased (APC = 2.17%, 95% CI: 1.35-3.01%). With increasing age, the burden of liver cancer decreased, while that of colorectal cancer rose. CONCLUSIONS: From 2005 to 2016, the cancer burden in the elderly in China decreased, mainly reflected in the non-fatal burden. Female breast and liver cancer were a more serious burden in the younger elderly, while colorectal cancer burden was mainly observed in the older elderly.
背景:随着人口老龄化,癌症负担日益突出。本研究基于中国癌症登记年报,量化了中国老年人(≥60 岁)的癌症负担,为癌症防控提供了流行病学证据。
方法:收集中国癌症登记年报 2008-2019 年≥60 岁老年人癌症发病和死亡数据,计算潜在寿命损失年(PYLL)和伤残调整寿命年(DALY),分析死亡和非致死性负担。采用 Joinpoint 模型分析时间趋势。
结果:2005-2016 年,老年人癌症 PYLL 率在 45.34‰-47.62‰之间保持稳定,而癌症 DALY 率呈年均 1.18%(95%CI:0.84-1.52%)的下降趋势。农村老年人的非致死性癌症负担高于城市老年人。肺癌、胃癌、肝癌、食管癌和结直肠癌是导致老年人癌症负担的主要癌症,占 DALY 的 74.3%。60-64 岁女性肺癌的 DALY 率呈上升趋势(APC=1.14%,95%CI:0.10-1.82%)。乳腺癌是 60-64 岁年龄组的五大癌症之一,DALY 率也呈上升趋势(APC=2.17%,95%CI:1.35-3.01%)。随着年龄的增长,肝癌负担降低,而结直肠癌负担增加。
结论:2005-2016 年,中国老年人癌症负担呈下降趋势,主要反映在非致死性负担方面。女性乳腺癌和肝癌在年轻老年人中负担更重,而结直肠癌负担主要见于较老年老年人。
