- Original description
The primary objective of this study was to evaluate the impact of a constructed shared decision (SDM) intervention (offering an option between colonoscopy and immunochemical collapsible occult blood testing (fecal immunochemical test; FIT)) on improving the incidence of high colonoscopy stromal in patients aged 40-49 years with a close relative suffering from colorectal cancer, compared to standard care (direct referral for colonoscopy).Read full original descriptionShow less
A Randomized Controlled Trial on Shared Decision-Making for Colorectal Cancer Screening Among High-Risk First-Degree Relatives Aged 40-49
The primary objective of this study was to evaluate the impact of a constructed shared decision (SDM) intervention (offering an option between colonoscopy and immunochemical collapsible occult blood testing (fecal immunochemical test; FIT)) on improving the incidence of high colonoscopy stromal in patients aged 40-49 years with a close relative suffering from colorectal cancer, compared to standard care (direct referral for colonoscopy).
Inclusion: Age 40 to 49 years at the time of recruitment; At least one immediate family member (biological parent, sibling, or child) has been pathologically diagnosed with colorectal cancer; Able to read, understand, and provide prior consent; Willing to be randomly assigned to any research group and complete all research procedures.
Exclusion: A personal history of colorectal cancer or inflammatory bowel disease (Crohn's disease or ulcerative colitis); Presence of warning signs of colorectal cancer requiring diagnostic evaluation rather than screening (e.g., unexplained rectal bleeding, significant involuntary weight loss, persistent changes in bowel habits); Presence of comorbidities that may contraindicate colonoscopy; Having undergone colonoscopy within the past three years; Inability to read, understand, and provide written informed consent.
