ABSTRACT

Background:

Cancer screening tests are recommended to prevent cancer-associated mortality by detecting precancerous and cancerous lesions in early stages. The COVID-19 pandemic disrupted the utilization of preventive health care services. While there was a rise in the number of cancer screening tests beginning in late 2020, screenings remained 29%-36% lower than in the pre-pandemic era.

Objective:

The objective of this review article was to assist health care providers in identifying approaches for prioritizing patients and increasing breast, cervical, and colorectal cancer screening during the uncertainty of the COVID-19 pandemic.

Methods:

We used the scoping review framework to identify articles on PubMed and EBSCO databases. A total of 403 articles were identified, and 23 articles were selected for this review. Literature review ranged from January 1st, 2020 to September 30th, 2021.

Results:

The articles included two primary categories of recommendations: (1) risk stratification and triage to prioritize screenings and (2) alternative methods to conduct cancer screenings. Risk stratification and triage recommendations focused on prioritizing high-risk patients with an abnormal or suspicious result on the previous screening test, of certain age group and sex, having personal medical or family history of cancers, currently symptomatic, predisposed to hereditary cancers, and cancer-causing mutations. Other recommended strategies included: identifying areas facing most disparities, creating algorithms and using artificial intelligence to create cancer-risk scores, leveraging in-person visits to assess cancer risk, and providing the option of open access screenings where patients can schedule screenings and can be assigned a priority category by health care staff. Some recommended using telemedicine to categorize patients and determine screening-eligibility for patients with new complaints. Several articles noted the importance of implementing preventive measures such as COVID-19 screening prior to the procedures, maintaining hygiene measures, and social distancing in waiting rooms. Alternative screening methods which do not require an in-person clinic visit and can effectively screen patients for cancers included mailing self-collection sampling kits for cervical and colorectal cancers and implementing or expanding mobile screening units.

Conclusions:

Although the COVID-19 pandemic had devastating effects on population health globally, it could be an opportunity to adapt and evolve cancer screening methods. Disruption often creates innovation, and focus on alternative methods for cancer screenings may help reach rural and under-resourced areas after the pandemic has ended.
