新冠疫情引发了全球范围内卫生服务的中断，包括癌症服务。我们进行了关于疫情对癌症预防服务（包括筛查）影响的叙事综述。在疫情的早期几个月里，服务受到了严重影响，并且在某些地区仍在恢复中。预计在未来几年中，将因这种中断导致大量额外的癌症或晚期癌症的发生。为了最大限度地减少对癌症预后的影响，有必要尽快恢复到疫情前的筛查和预防活动水平，甚至超过这些水平。恢复服务应解决健康不平等问题。《医学年度综述》第75卷的最终在线出版日期预计为2024年1月。有关修订估计，请参阅http://www.annualreviews.org/page/journal/pubdates。

The COVID-19 pandemic led to disruption of health services around the world, including cancer services. We carried out a narrative review of the effect of the pandemic on cancer prevention services, including screening. Services were severely affected in the early months of the pandemic, and in some areas are still recovering. Large numbers of additional cancers or additional late-stage cancers have been predicted to arise over the coming years as a result of this disruption. To minimize the effects on cancer outcomes, it is necessary to return as quickly as possible to prepandemic levels of screening and prevention activity or indeed to exceed these levels. The recovery of services should address health inequalities. Expected final online publication date for the Annual Review of Medicine, Volume 75 is January 2024.
