Simple at-home tests called FIT kits are a noninvasive way to keep up on recommended screenings for colorectal cancer. 

A Course Reset on Colorectal Cancer Screening

Threat of COVID-19 infection kept millions of Americans from getting routine cancer screenings early in the pandemic. But research indicates screenings still lagged by the beginning of 2021, especially colonoscopies.

A study published in Cancer, which included more than 700 cancer facilities nationwide, found by January 2021 most of those surveyed had not seen screenings rebound to prepandemic levels. Colonoscopies dropped by nearly half compared to 2019.

At the same time, new cancer diagnoses dropped 13 to 23%, depending on the type, because fewer cases were being detected.

To help get some Chicagoans back on track and improve health outcomes, Blue Cross and Blue Shield of Illinois (BCBSIL) and its South and Westside Blue Door Neighborhood Centers (BDNC) recently launched a three-year colon cancer screening initiative. It has partnered with the American Cancer Society, Colorectal Cancer Alliance, Gilda’s Club and Sinai Chicago.

The Morgan Park and Lawndale centers, located in some of Chicago’s most underserved ZIP codes, held events where medical experts and colon cancer survivors educated residents about the disease and explained the importance of early screening and diagnosis.

“The audience was very interested in the survivor stories,” says Laron Taylor, BDNC director. “They had many questions about the symptoms and were very interested in hearing their experiences with overcoming colorectal cancer.”

Those who attended the events participated in healthy-cooking and exercise demonstrations. They also were offered free at-home colorectal cancer screening tests, fecal immunochemical test (FIT) kits, an effective and less invasive screening for colorectal cancer.

“We know that in some communities we've seen a disparity in both the incidence of colorectal cancer as well as death rates from colorectal cancer,” says Dr. Derek Robinson, BCBSIL vice president and chief medical officer.

“Certainly in the African-American community we see a death rate that is much higher than what we see in other communities," Robinson says. "It's really important that we educate people regarding both the things that may place them at greater risk for colorectal cancer as well as updated recommendations to begin screening at age 45 for those of average risk for colorectal cancer.”

Colorectal cancer is the third most common cancer diagnosed in the United States, according to the American Cancer Society. It’s the second most common cause of cancer deaths for men and women combined and expected to cause more than 52,500 deaths this year.

For years, BCBSIL has offered some eligible members FIT kits to screen themselves for colorectal cancer and return them for analysis. After the COVID-19 outbreak forced most Illinoisans to stay home in 2020, BCBSIL increased efforts to send FIT kits to members and encourage home testing.

With a FIT kit, a stick or brush is used to collect a small stool sample, which is returned to a doctor or lab where the sample is checked for blood — which could be an early sign of colorectal cancer. A colonoscopy is recommended as a follow-up test if a FIT kit detects blood.

In 2021, the company sent kits to more than 15,500 BCBSIL retail members who were at least 45 years old and had not had a colonoscopy. Results were shared only with the participating members and the primary care provider they identified.

Of the 2,661 members who performed the tests and returned them for analysis, 121 had abnormal results and were encouraged to schedule follow-up colonoscopies.

“Colorectal cancer screening should be on the to do list for everyone,” Robinson says. “We can actually prevent cancer from occurring through early screening. We’ve got some catching up to do.”

Pandemic impacts cancer diagnoses

BCBSIL claims data suggests the pandemic may have affected screening rates for several cancers. However, company leaders do not anticipate a surge in cancer diagnoses despite a screening lag.

Diagnoses for at least five cancer categories — colorectal, cervical, prostate, lung and breast — plunged almost immediately after the pandemic was declared in 2020. However, diagnoses rates for all five quickly increased as communities eased COVID-19 restrictions and doctor’s offices and clinics reopened to treat more patients.

Dr. Mitch Magee, oncology medical director for BCBSIL, says the swift rebound indicates short COVID-related delays didn’t substantially prohibit members from seeking care and probably won’t dramatically affect their treatment. He says research published in the Annals of Thoracic Surgery indicates treatment delays up to three months for some lung cancers did not significantly affect five-year survival rates.

“A delay of a month is not going to make a big difference in the stage of cancer at diagnosis or treatment outcomes going forward,” says Magee, a thoracic surgeon. “Delays are bad, but long delays are worse.”

In 2021, BCBSIL helped close some gaps by reaching out to more than 275 eligible members and scheduling them for breast and colorectal cancer screenings. Almost 100 others received rewards for completing breast cancer screenings.

“We need to ensure that individuals know that it is safe to return to care and do so armed with a screening priority list informed by knowledge of how based upon their age, family history and other risk factors affect their risks for cancer,” Robinson says.
