Impact of the suspension and restart of the Dutch breast cancer screening program on breast cancer incidence and stage during the COVID-19 pandemic.
The COVID-19 pandemic forced the Dutch national breast screening program to a halt in week 12, 2020. In week 26, the breast program was resumed at 40% capacity, which increased to 60% in week 34. We examined the impact of the suspension and restart of the screening program on the incidence of screen-detected and non-screen-detected breast cancer. ⋯ The decrease in incidence was seen in all age groups and mainly occurred for cTis, cT1, DCIS, and stage I tumors. Due to the suspension of the breast cancer screening program, and the restart at reduced capacity, the incidence of screen-detected breast tumors decreased by 67% during weeks 9-35 2020, which equates to about 2000 potentially delayed breast cancer diagnoses. Up to August 2020 there was no indication of a shift towards higher stage breast cancers after restart of the screening.

Mitigating the impact of COVID-19 on colorectal cancer screening: Organized service screening perspectives from the Asia-Pacific region.
Colorectal cancer(CRC) is one of the most prevalent malignancies in the Asia-Pacific region, and many countries in this region have launched population CRC service screening. In this study, CRC screening key indicators, including the FIT(fecal immunochemical test) screening rate (or participation rate) and the rate of undergoing colonoscopy after positive FIT in 2019 and 2020, were surveyed in individual countries in the Asia-Pacific region. The impact of the pandemic on the effectiveness of CRC screening was simulated given different screening rates and colonoscopy rates and assuming the pandemic would persist or remain poorly controlled for a long period of time, using the empirical data from the Taiwanese program and the CRC natural history model. ⋯ The modeling study revealed that prolonged pauses of screening led to 6% lower effectiveness in reducing CRC mortality. Screening organizers should coordinate with health authorities to elaborate on addressing screening backlogs, setting priorities for screening, and applying modern technologies to overcome potential obstacles. Many novel approaches that were developed and applied during the COVID-19 pandemic, such as the risk-stratified approach that takes into account personal CRC risk and the local epidemic status, as well as new digital technologies, are expected to play important roles in CRC screening in the future.

Leveraging vertical COVID-19 investments to improve monitoring of cancer screening programme - A case study from Bangladesh.
Cancer screening programs from majority of the low- and middle-income countries (LMICs) report screening coverage as the only performance indicator, and that too measured through population-based sample surveys. Such information is unreliable and has very little value in assessing programmatic quality and impact. Regular monitoring of key process and outcome indicators based on data collected through a robust information system is essential to ensure quality of a screening programme. ⋯ The rate rapidly recovered as the program intensified screening in the hard-to-reach regions less affected by the pandemic and expanded the outreach services. Other LMICs may emulate Bangladesh example. Customizing the information system developed for pandemic surveillance to collect cancer screening data will help them build back the screening programs better.

COVID-19 impact on screening test volume through the National Breast and Cervical Cancer early detection program, January-June 2020, in the United States.
Women from racial and ethnic minority groups face a disproportionate burden of cervical and breast cancers in the United States. The Coronavirus Disease 2019 (COVID-19) pandemic might exacerbate these disparities as supply and demand for screening services are reduced. The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides cancer screening services to women with low income and inadequate health insurance. ⋯ Test volume began to recover in May and, by June 2020, NBCCEDP breast and cervical cancer screening test volume was 39% and 40% below the 5-year average for that month, respectively. However, breast cancer screening remained over 50% below the 5-year average among women in rural areas. NBCCEDP programs reported assisting health care providers resume screening.

Understanding COVID-19 impact on cervical, breast, and colorectal cancer screening among federally qualified healthcare centers participating in "Back on track with screening" quality improvement projects.
The COVID-19 pandemic has contributed to decreases in breast, colorectal, and cervical cancer screenings between 86 and 94% compared to three-year averages. These postponed screenings have created backlogs that systems will need to address as healthcare facilities re-open for preventive care. The American Cancer Society is leading a 17-month intervention with 22 federally qualified health centers (FQHCs) across the United States aimed at reducing cancer incidence and mortality disparities and alleviating additional strain caused by COVID-19. ⋯ FQHCs provide critical cancer prevention services to vulnerable populations. The delivery of culturally competent, high-quality healthcare can mitigate and potentially reverse racial and ethnic disparities in cancer prevention testing and treatment. Ensuring and expanding access to care as we move out of the pandemic will be critical to preventing excess cancer incidence and mortality in vulnerable populations.
