高齢者の大腸ポリープに対する大腸内視鏡検査 vs 便検査 (COOP)
大腸ポリープの既往のある高齢者に対する大腸内視鏡検査と便検査の比較
This is a multi-site comparative effectiveness randomized controlled trial (RCT) comparing annual fecal immunochemical testing (FIT) and colonoscopy for post-polypectomy surveillance among adults aged 65-82 with a history of colorectal polyps who are due for surveillance colonoscopy.
調査の概要
詳細な説明
Colon polyps are common among adults ≥50 years and people with colon polyps are recommended to undergo regular follow-up colonoscopy (surveillance) in hopes of preventing subsequent colorectal cancer (CRC). Older adults, particularly those who are age ≥70 years, most of whom have a history of only small colon polyps, may benefit little from repeated colonoscopies because of the increased risks of colonoscopy due to age and co-morbidities and potentially limited life expectancy due to other competing medical problems - CRC may never be a problem for them. Older adults may also be hesitant to get repeated colonoscopy because of the risk of complications (e.g., bleeding, perforation, etc.) and inconvenience. More surveillance options are needed to help address the concerns and challenges with repeated colonoscopies in older adults with a history of low-risk polyps.
FIT is a noninvasive, stool-based test that is recommended and widely used in the US and globally for CRC screening in average-risk adults 45 to 75 years of age. In addition, FIT is already standard of care as a surveillance option for patients with a history of low-risk adenomas in Canada and has been shown to be equivalent to colonoscopy for screening of certain high-risk populations (e.g., those with a family history of CRC). However, FIT's role for surveillance among older adults who have a history of low-risk adenomas has not been studied in the US nor among older adults who may benefit from this noninvasive surveillance approach.
The COOP Trial will fill this evidence gap and shed light on patient-, clinician-, and system-factors relevant to FIT for surveillance that together could potentially transform surveillance guidelines in the US and beyond
The purpose of this study is to compare annual at-home stool-based testing, with a fecal immunochemical test (FIT), to colonoscopy in adults age 65-82 who have a history of colorectal polyps. The goal of the study is to compare how well FIT works compared to colonoscopy in looking for and finding colorectal cancer in older adults who have a history of colorectal polyps, as well as to understand people's experiences with using it compared to colonoscopy.

|
The investigators will determine the incidence of advanced neoplasia, defined as adenocarcinoma of the colon or rectum or adenomas or serrated polyps ≥1 cm in size or with villous features or any dysplasia, or traditional serrated polyps, in both study groups through annual surveys asking about any changes in polyp history or new cancer diagnosis for up to 6 years and medical record review for up to 11 years. The incidence of advanced neoplasia will be compared between the two study group cumulatively after all the data has been collected. |

Change from baseline Satisfaction and Trust of colorectal screening testing assessed by Tiro et al (2005) Response Efficacy sub-scale from the general colorectal cancer screening survey.
時間枠:Baseline, 1 year after surveillance colonoscopy, annually after each completed FIT for up to 6 years
|
The Response Efficacy sub-scale from the general colorectal cancer screening survey is a 2 item scale with five response options (1=strongly disagree, 2=mildly disagree, 3=don't know, 4=mildly agree, 5=strongly agree), such that each individual attains a score ranging from 2 to 10. |

Change from baseline worry about colorectal Cancer assessed by the Cancer Worry Scale (CWS)
時間枠:Baseline and annually for up to 6 years
|
The Cancer Worry Scale is a six-item scale designed to measure worry about the risk of developing cancer and the impact of worry on daily functioning. The scale consists of six questions with four response options (1 = not at all or rarely; 2 = sometimes; 3 = often; 4 = almost all the time), such that each individual attains a score ranging from 6 (minimum worry) to 24 (maximum worry). |
Baseline and annually for up to 6 years

時間枠:Baseline, annually for up to 6 years
|
The absolute perceived susceptibility to colorectal polyps subscale from McQueen (2010) is a three-question scale using four-point Likert format ranging from 1= strongly disagree to 4=strongly agree, such that each individual attains a score ranging from 3 (minimum susceptibility) to 12 (maximum susceptibility). |
Baseline, annually for up to 6 years
|

Change from baseline Emotional benefit of surveillance assessed by a modified version of the Psychological Consequences Questionnaire (PCQ)
時間枠:Baseline and annually for up to 6 years
|
The PCQ is a 22 question scale that has four response options (1=Not at all, 2=a little bit, 3=quite a bit, 4=a great deal) such that each individual attains a score ranging from 22 to 88. |
Baseline and annually for up to 6 years
|
|
Change from baseline perceived global health assessed by the Patient-Reported Outcomes Measurement Information System-Global 10
時間枠:Baseline and annually for up to 6 years
|
The Patient-Reported Outcomes Measurement Information System-10 is a 10-item scale that has five response options (5=excellent, 4=very good, 3=good, 2=fair, 1=poor) which assess overall QOL. Raw scores are transformed into T scores; higher T scores indicate greater endorsement of the construct being assessed. Scoring supports two summary scores: A Global Physical Health (GPH) score and a Global Mental Health (GMH) score. |
Baseline and annually for up to 6 years

|
Major and minor harms within 30 days of colonoscopy, as measured through chart review and telephone interview.
時間枠:30-45 days post colonoscopy for up to 6 years
|
Major and minor harms within 30 days of colonoscopy will be collected through chart review and a telephone interview with participants 30-45 post study surveillance colonoscopy or study colonoscopy for positive FIT. The incidence of harms will be compared between the study groups (annual FIT and colonoscopy). |
30-45 days post colonoscopy for up to 6 years
