California was the first U.S. state to enact a shelter-in-place order in March 2020.
By the next month, the Centers for Disease Control and Prevention and the Centers for Medicare and Medicaid Services recommended that patients delay routine cancer screenings and other non-essential medical appointments. This led to about 40% of U.S. adults avoiding medical care, including screenings such as colonoscopies, mammograms, and other diagnostic measures.
In a new report, researchers at UC Davis Comprehensive Cancer Center found significantly fewer cancers were diagnosed in 2020 for 17 of 21 common cancer types. The report was produced by the California Cancer Reporting and Epidemiologic Surveillance (CalCARES) program within the cancer center.
The cancer center is urging Californians and health care providers to get their routine screenings back on track.
Almost 13% of expected screening-detectable cancer cases went undiagnosed
The UC Davis researchers used cancer incident cases among California residents between 2005 and 2020 from the California Cancer Registry. They compared reported 2020 cancer incidence rates with American Cancer Society estimates of expected new invasive cancers in California for 21 common cancers. The cancer center partners with the California Department of Public Health to manage day-to-day operation of the cancer registry.
There were many cancers with significantly lower than expected diagnoses in 2020. These included oral cavity and pharynx, thyroid, liver and bile duct, cervical, lung and bronchial, breast, stomach, uterine, ovary, bladder, kidney, colorectal, and pancreatic cancers, as well as melanoma, leukemia, myeloma, and non-Hodgkin lymphoma.
Strikingly, the research team estimated that only 55% of the expected number of oral cavity and pharynx cancers, and only 75% of the expected number of thyroid cancers were diagnosed in California in 2020. In all, 12.9% fewer screening-detectable cancers were diagnosed in 2020 than 2019.
Importantly, there were 25-50% fewer than expected early-stage diagnoses made among all screening-detectable cancer sites, including breast, cervical, colorectal, melanoma and lung, as well as among specific population subgroups.
