Differences in all-cancer mortality by rural vs. urban status exist; limited information exists regarding how lung cancer contributes to these differences. We describe the contribution of lung cancer to rural-urban differences in all-cancer death rates.
We used National Vital Statistics System data to calculate age-adjusted lung cancer death rates by rural vs. urban status, overall and by multiple subgroups. We calculated the average annual percent change in cancer death rates by rural vs. urban status between 1999-2020, and percentage contribution of lung cancer to excess all-cancer mortality in rural counties in 2020.
In 2020, lung cancer death rates were higher in rural counties among females (33.5 vs. 25.7) and males (49.0 vs. 35.9). Between 1999-2020, larger declines in lung cancer death rates were generally observed in urban counties. In 2020, lung cancer contributed 44.4 % to the excess all-cancer mortality in rural counties.
Lung cancer death rates were generally higher in rural counties, and differences in death rates increased over time. In 2020, lung cancer contributed a large percentage to excess all-cancer mortality in rural counties. Implementation of interventions to improve lung cancer prevention, screening, and treatment might reduce rural-urban differences in cancer deaths.
农村与城市地区的全癌死亡率存在差异；关于肺癌如何导致这些差异的信息有限。我们描述了肺癌对农村与城市地区全癌死亡率差异的影响。
我们使用国家生命统计系统的数据，计算了按农村与城市地区划分的总体及多个亚组的年龄调整肺癌死亡率。我们计算了1999 - 2020年间农村与城市地区癌症死亡率的年均变化百分比，以及2020年肺癌对农村县全癌死亡率过高的贡献率。
2020年，农村县女性肺癌死亡率（33.5对25.7）和男性肺癌死亡率（49.0对35.9）更高。1999 - 2020年间，城市县肺癌死亡率的下降幅度通常更大。2020年，肺癌对农村县全癌死亡率过高的贡献率为44.4%。
农村县肺癌死亡率总体较高，且死亡率差异随时间增加。2020年，肺癌对农村县全癌死亡率过高的贡献率很大。实施改善肺癌预防、筛查和治疗的干预措施可能会减少农村与城市地区癌症死亡的差异。
