The program offers free FIT testing once every 2 years to people 5069 years old. The primary outcome was the diagnostic performance of FIT for detecting CRC or AN. BM, Parton
In this meta-analysis, FIT has high overall diagnostic accuracy for CRC and moderate accuracy for advanced neoplasia. Another study examined the merits of colonoscopy in patients with negative FIT tests in a large program that conducted annual screening. Inc32,37; OC-light, Eiken Chemical28; and HemeSelect, Smith-Kline Diagnostics30). The average sensitivity of FIT for CRC was 93% (95% CI, 53%-99%), and the average specificity was 91% (95% CI, 89%-92%), yielding a positive likelihood ratio (LR+) of 10.30 (CI 7.7-13.9) and a negative likelihood ratio (LR) of 0.08 (95% CI, 0.01-0.75) (GRADE: very low).

The latest US Preventive Services Task Force recommendations for colorectal screening support that the best screening test is the one that gets done, and that the ultimate goal of screening strategies is maximization of screening uptake to reduce CRC mortality.45, Although our results verify the diagnostic accuracy of FIT for CRC in individuals at increased risk, this body of evidence is limited by a relatively small sample size. The FIT identified patients with CRC with overall high sensitivity but missed nearly 50% of small (T1) and 32% of UICC stage I CRCs. This study shows that even with a national health service that provides universal coverage, there are other barriers to obtaining care, Dr. Breslau said. Individuals at average risk are screened using the fecal immunochemical test (FIT), which has been available in British Columbia for the past 5 years Colonoscopy is a good test for finding polyps or cancer in the bowel. Applying Grading of Recommendations Assessment, Development and Evaluation (GRADE) to diagnostic tests was challenging but doable. L,
Given the safety, simplicity, low cost, and minimal discomfort of FIT, it is a viable alternative screening strategy for patients at increased risk for CRC. On the other hand, our results also show that FIT could diagnose only half of the cases with AN. ST, Oort

It is a very sensitive test, and that polyps, hemorrhoids (both internal and external), and ulcers can all cause a positive fit test. MH, Hardcastle
However, those who did not get a follow-up colonoscopy were about twice as likely to die of colorectal cancer over a 10-year period as those who did have a follow-up colonoscopy. Ng

Further research is needed to assess whether this relationship . FIT testing is recommended annually, and Cologuard every three years if testing is negative, but positive test results require a follow-up with colonoscopy. et al. It is also important to establish optimal thresholds, test cutoff values, and number and frequency of FIT samples.10 Our results also should prompt randomized trials to assess the implementation of FIT either alone or in combination with other screening procedures into screening strategies for increased-risk individuals.

Conclusions and Relevance
This study will investigate the use of digital rectal exam (DRE) to obtain stool samples for the fecal immunochemical test (FIT) in patients due for screening colonoscopy and in pre-operative patients with known colorectal cancer. Study supervision: Katsoula, Haidich, Tsapas, Giouleme. FIT costs about $20 or less and is covered by Medicare and most health insurance plans. CA. M,
This research provides additional valuable information to the body of high-quality comparative evidence about the diagnostic accuracy of FIT screening compared with other fecal tests or colonoscopy, Carlo Senore, MD, and Manuel Zorzi, MD, wrote in a related editorial. et al. Moreover, we conducted a sensitivity analysis excluding studies that used delayed colonoscopy as the reference standard. The FIT has high overall diagnostic accuracy for CRC but moderate accuracy for AN in patients at above-average personal or familial risk. Subgroup analyses indicated that FIT cutoff values between 15- and 25-g/g feces provided the best combination of sensitivity and specificity for the diagnosis of CRC (93% and 94%, respectively). Only about 4% of people will have cancer found on colonoscopy. et al. How Fit Is FIT for Detecting Colorectal Cancer? A prospective, controlled, feasibility study.

We assessed the quality of the evidence in our main analysis but also separately for patients with family history or personal history of CRC. Eleven studies were cross-sectional and 1 was a randomized clinical trial.34 Two studies were reported only in abstract form.26,36 Nine studies included only first-degree relatives of CRC patients.26-28,30,32-34,36,37 Three studies included individuals either with a family history of CRC or prior history of CRC or advanced adenomas.29,31,35 Of these, only 2 studies reported results for subgroups.31,35, Eight studies evaluated quantitative FIT (OC-sensor/OC-micro, Eiken Chemical),26,27,29,31,33-36 while 4 studies used qualitative FITs (Hemosure, W.H.P.M. Importance
First and foremost, a positive result on the Cologuard test means that you need to have a colonoscopy. We explored the diagnostic accuracy at 3 different FIT thresholds (<15 g Hb/g, 15 to 25 g Hb/g, >25 g Hb/g feces) based on existing practice and to maximize sensitivity for an increased-risk population. Based on GRADE summaries (eTable 2 in the Supplement) we deemed the quality of the evidence to be low or very low. This means that when the test came out positive, there actually was an abnormality 90 percent of the time with Cologuard and 95 percent of the time with FIT. Quantitative and 1-sample FIT showed adequate test performance, but data on other FIT brands and multiple samples were insufficient. Respective values for AN were sensitivity, 46% (95% CI, 37%-56%); specificity, 93% (95% CI, 90%-95%); LR+, 6.60 (95% CI, 4.90-8.70); and LR, 0.58 (95% CI, 0.48-0.69). Heterogeneity and small sample sizes undermine the quality and validity of these findings. We also searched trial registries and abstracts from relevant scientific meetings, as well as scanned websites of companies manufacturing FITs. independently evaluated the quality of included studies using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool.15 Discrepancies were resolved by consensus. 1 In order to reduce mortality and incidence of CRC, the National Health Service Bowel Cancer Screening Programme (NHS BCSP) in . et al. In a study from the Netherlands, 4523 people (age range, 50-74) underwent FIT screening with OC-Sensor Micro; a hemoglobin concentration of 50 ng/mL was considered positive. Screening colonoscopy was better at finding cancer and pre-cancerous polyps than both Cologuard and the FIT test. AZ, Quintero

What is the diagnostic accuracy of fecal immunochemical testing (FIT) for screening of colorectal cancer (CRC) or advanced neoplasia in asymptomatic high-risk populations? Colorectal cancer (CRC) is the third most common type of cancer in men and the second most common in women worldwide.

These data support the annual use of FIT in individuals at increased risk for CRC as an alternative screening strategy for patients who refuse to use colonoscopy. Fecal immunochemical test (FIT). It looks for tiny traces of blood that you might not be able to see and which could be a sign of cancer. Lin
The rate increased with age, but the rates found at all ages are much lower than rates of cancer in people undergoing screening colonoscopy without a prior FIT, lead authors George F. Longstreth, MD, and Daniel S. Anderson, MD, FACP, of Kaiser Permanente, Southern California, San Diego, told CLN Stat in a statement. The Cologuard test has a 13% false-positive rate, which means 1 in 10 positive tests will incorrectly identify cancer or polyps. . Main Outcomes and Measures
If cancer is detected, treatment is usually the next step. The FIT has high overall diagnostic accuracy for CRC but moderate accuracy for AN in patients at above-average personal or familial risk. et al. RM, Whiting
What an abnormal FIT result really means - British Columbia Medical Journal They used Union for International Cancer Control (UICC) stage and T stage (infiltration) to measure sensitivity. People with a positive FIT test result are advised to have a colonoscopy to investigate the cause of the bleeding because a FIT test alone cannot diagnose cancer. We excluded studies with symptomatic patients or patients with inflammatory bowel disease, hereditary nonpolyposis colorectal cancer, familial adenomatous polyposis, or studies for which 22 diagnostic tables could not be inferred. All Rights Reserved. The ongoing NCI-funded PROSPR program aims to better understand how to improve the cancer screening process and reduce disparities in colorectal and other cancer screening in community health care settings in the United States. We estimated whether non-compliance with colonoscopy after a positive FIT is associated with increased CRC incidence and mortality. Levi
In the new study, researchers found that people who had a positive FIT result (signs of blood in the stool) but did not have a follow-up colonoscopy were twice as likely to die as those who did have a follow-up colonoscopy. In the study, Imperiale and his colleagues determined that when the FIT was set to be more sensitive, the test caught 95 percent of cancers, but resulted in 10 percent false positives.

Subgroup analyses indicated that FIT cutoff values between 15- and 25-g/g feces provided the best combination of sensitivity and specificity for the diagnosis of CRC (93% and 94%, respectively).
Bowel cancer screening: having a colonoscopy - GOV.UK Quiz Ref IDColorectal cancer (CRC) is the third most common type of cancer in men and the second most common in women worldwide.1 Early detection of CRC through widely applied screening programs has proven to be effective in reduction of cancer-related mortality. The researchers compared the numbers of new colorectal cancer cases diagnosed, deaths from colorectal cancer, and deaths from any cause in the two groups over time for up to 10 years after an initial positive FIT result. However, FIT positivity rates and positive predictive value (PPV) can vary substantially, with false-positive (FP) results adding to colonoscopy burden without improving cancer detection. As the broader DG30 criteria create a potentially enormous pool of low-risk patients, triage with FIT may lead to an overall increase in patients with false-positive . L, Sarasqueta

The average sensitivity of FIT for AN was 48% (95% CI, 39%-57%); and the average specificity was 93% (95% CI, 91%-94%), yielding an LR+ of 6.55 (95% CI, 5.0-8.5) and an LR of 0.57 (95% CI, 0.48-0.67) (GRADE: very low). L, Gorber
It has recently been suggested that fecal immunochemical testing (FIT) could be used for population-based screening owing to its high accuracy and adherence.7-9 Previous systematic reviews and meta-analyses have assessed the performance of FIT in average-risk populations.10,11 However, the potential role of FIT for screening of individuals at increased risk for CRC has not yet been fully elucidated. Also, there are no diet or drug restrictions. Sensitivity was particularly low for T1 and stage I cancers in the distal colon (32% and 52%, respectively) although generally very high for cancers with higher T stage (T2-T4) and more advanced stage (UICC stage . Not a virtual colonoscopy, or another stool test, or another scan of some sortyou need a real optical colonoscopy. Multiple factors can contribute to people not getting follow-up colonoscopy exams, both he and Dr. Breslau said. Drafting of the manuscript: Katsoula, Paschos, Tsapas. Both studies appear in the Clinical Gastroenterology and Hepatology journal. New research underlines the importance of following up with a colonoscopy exam after a positive (abnormal) result on an at-home stool test to screen for colorectal cancer. A negative Cologuard test means that the home test did not detect significant levels of DNA and/or hemoglobin biomarkers in the stool that are associated with colorectal cancer. Of those, about 1.2% have a positive fit test result.
