According to a new study led by researchers at the American Cancer Society (ACS), the COVID-19 pandemic increased the number of cancer-related deaths by 3.2% in the United States from 2019 to 2020. The related death rate was highest in April 2020, when the ability to Healthcare is more challenging due to the pandemic. Mortality rates were observed to rise again each month from July to December 2020 compared to 2019. The results will be presented at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago, June 3-7.
In the study, researchers led by Jingchuan Zhao, chief scientist involved in Health Services Research at the American Cancer Society, used the 2019-2020 U.S. Multiple Causes of Death Database from the Centers for Disease Control and Prevention to identify cancer-related deaths, defined as infected deaths. invasive cancer as a contributing cause of death. They compared age-standardized annual and monthly cancer-related death rates (per 100,000 person-years and person-month, respectively) in January-December 2020 (epidemic) versus January-December 2019 (pre-pandemic) overall and broken down by breed and location the death. Scientists calculated the 2020 excess mortality by comparing the numbers of observed deaths with the expected deaths based on age-specific cancer-related mortality from 2015 to 2019.
The results showed that the number of cancer-related deaths amounted to 686,054 in 2020, up from 664,888 in 2019, with an annual increase of 3.2%. Compared to the projected number of deaths for 2020 (666,286), the number of excess cancer-related deaths was 19,688 in 2020. The age-standardized annual cancer-related death rate has consistently decreased from 173.7 in 2015 to 162.1 in 2019, while increasing. to 164.1 in 2020. The monthly cancer-related death rate was higher in April 2020 when health care facilities were more challenged by COVID-19, and subsequently decreased in May and June 2020, and higher death rates were observed again every month from July to December 2020 Compared to 2019. In large urban areas, the largest increase in cancer-related deaths was observed in April 2020, while in non-urban areas, the largest increases occurred from July to December 2020, coinciding with the spatiotemporal pattern of COVID-19 incidence in the country. Compared to 2019, cancer-related death rates were lower from March to December 2020 in medical facilities, hospice care facilities, and nursing homes or long-term care settings but higher in the homes of the deceased.
The study authors emphasize ongoing assessment of the spatio-temporal impacts of the epidemic on cancer care and outcomes are warranted, particularly with regard to vaccine uptake patterns and COVID-19 hospitalization rates.
