Accuracy and Predictive Values for Colorectal Cancer of Quantitative FIT in Symptomatic Patients in Primary Care

December 1, 2021 updated by: Louise Olsson, Region Örebro County

Accuracy and Predictive Values for Colorectal Cancer of a Quantitative Faecal Immunochemical Test in Symptomatic Patients in Primary Care

The aim of this study is to determine accuracy and predictive values for colorectal cancer of a faecal quantitative immunochemical test (FIT) in unselected symptomatic patients presenting in primary care. Main reference test will be linkage to a nationwide colorectal cancer registry.

Detailed Description

This is a nationwide multi-centre study in primary care, Sweden. Patients from the age of 40 years and above presenting in primary care with symptoms associated with colorectal cancer prompting their GP to take actions are eligible.

Consenting patients will fill out a short form on symptoms during last 4 weeks. They will provide 2 faecal samples from 2 different days. Samples will be analysed at any of three laboratories within 5 days using QuikRead go® (Aidian Oy). The analytical working range is 10-200 µg Hb/g faeces. The outcome will be reported as the concentration of first test (FIT 1) and highest concentration of two tests (FIT max). The outcome of the study FIT will remain within the study and GPs must request a separate FOBT for clinical purposes.

Reference test will be linkage to the Swedish Colorectal Cancer Registry (with in practice complete coverage) after at most 2 years for all patients. Accuracy and predictive values will be determined and ROC-curves analysed.

Some patients included in the study will be referred for colonoscopy for clinical reasons, and the outcome of FIT in relation to colonoscopy findings will be reported for this group as well.

Study Population

Patients aged ≥ 40 years presenting in primary care with symptoms associated with colorectal cancer prompting their GP to take actions are eligible. This involves referral for any endoscopic or radiological examination of the large bowel, laboratory testing, including faecal occult blood test according to local routines, or clinical follow-up within soon. Both urgent referrals and patients planned for at least initial management in primary care are eligible, ie there will be no attempt to delimitate the study population based on any categorization of symptoms into "alarm" and "non-alarm" symptoms. The study population will be defined by primary care physicians´ clinical reasoning and assessment of colorectal cancer as a (more or less) possible diagnosis at the unique consultation.
