ANN ARBOR, Mich., Nov. 29, 2022 /PRNewswire/ -- While the screening by Fecal Immunochemical Test (FIT) can detect colorectal cancers early, successful treatment depends on patients undergoing follow-up colonoscopies after testing positive. The original research paper, Reasons for no colonoscopy after an unfavorable screening result in Dutch colorectal cancer screening: a nation–wide questionnaire in the November/December 2022 edition of Annals of Family Medicine examines the reasons why some patients don't seek follow-up care after a positive FIT test.

Participants in colorectal cancer screening who do not follow up after an unfavorable result may benefit from personalized counseling.
A better understanding of why individuals do not follow-up has global implications for all individuals at risk of colorectal cancer (CRC) as it is best treated early.
The Netherlands started implementation of the two-step Dutch CRC screening program in 2014. All individuals aged 55-75 receive a FIT and an information sheet by mail. Those having a positive FIT (indicating an increased risk of CRC) receive the result plus a prescheduled appointment for consultation to discuss the follow-up colonoscopy by mail.
In this study, the researchers distributed a survey among 4,006 individuals who had received a positive FIT. Of the 2,225 respondents, 730 reported not having undergone a follow-up colonoscopy. Of those, 404 (55%) reported a contraindication for colonoscopy, including chronic illness, or having had a recent colonoscopy.
Other reasons individuals opted against follow-up care included:
Having difficulty deciding to undergo colonoscopy or not
Lack of opportunity to discuss the FIT outcome with their doctor
The belief that the test result is a false positive
The perception of having low estimated CRC risk
Having trust in their own ability to self-detect CRC
A belief that polyp removal was ineffective
The perception that colonoscopies are uncomfortable
The strongest driver to follow-up with colonoscopy after a positive screening was the belief that a patient's family physician would support their decision. Given that a lack of knowledge, misperception of CRC risk, and/or decision–making difficulties hinder follow-up, the authors argue that improving knowledge and offering personal guidance might prove beneficial for FIT–positive individuals. They suggest personalized counseling from family practitioners may help.
