Cancer incidence declined during the COVID-19 pandemic in part due to health care delivery challenges. We examined the impact of the COVID-19 pandemic on changes in lung cancer incidence.
We used 2019-2020 US Cancer Statistics data from 49 cancer registries covering 97 % of the US population. We calculated the number of new lung cancer diagnoses in 2019 and 2020, age-adjusted lung cancer incidence rates per 100,000 persons, and 2019-to-2020 % changes in incidence rates. We also calculated number and percentage of new lung cancer diagnoses by month and stage at diagnosis.
The age-adjusted lung cancer incidence rate per 100,000 persons was 47.9 in 2019 vs. 41.4 in 2020-a 13.6 % decrease. Differences in the percentage change in incidence rates were observed by age, race and ethnicity, US census region, histology, and stage at diagnosis. A higher percentage of people were diagnosed at distant stage in 2020 than 2019.
This report provides new insight into subgroups that experienced the greatest decline in observed lung cancer incidence during the first year of the COVID-19 pandemic. The findings can be used to inform intervention efforts to improve lung cancer screening, diagnosis, and treatment.
由于医疗保健服务方面的挑战，COVID-19 大流行期间癌症发病率有所下降。本研究旨在探讨 COVID-19 大流行对肺癌发病率变化的影响。
本研究使用了来自 49 个癌症登记处的 2019-2020 年美国癌症统计数据，覆盖了美国 97%的人口。我们计算了 2019 年和 2020 年的新肺癌诊断病例数、每 10 万人年龄调整后的肺癌发病率以及发病率的 2019-2020 年变化百分比。我们还按月和诊断时的分期计算了新肺癌诊断病例的数量和百分比。
2019 年每 10 万人年龄调整后的肺癌发病率为 47.9，2020 年为 41.4，下降了 13.6%。不同年龄、种族和民族、美国人口普查区、组织学和诊断时的分期观察到发病率变化百分比存在差异。2020 年远处分期诊断的患者比例高于 2019 年。
本报告为了解 COVID-19 大流行第一年观察到的肺癌发病率下降最大的亚组提供了新的见解。这些发现可用于为改善肺癌筛查、诊断和治疗提供干预措施的信息。
