Anatomical location of colorectal neoplasia in patients with positive stool test (multitarget stool DNA or fecal immunochemical test) results: data from the New Hampshire Colonoscopy Registry.
Background and aims: Data comparing the location of polyp yield in patients with positive stool test results can aid screening test selection. We conducted a cross-sectional analysis of New Hampshire Colonoscopy Registry data to compare the location, left versus right side of the colon, of neoplasia detected on colonoscopy after a multitarget stool DNA (mt-sDNA) test or a fecal immunochemical test (FIT), compared with a reference group undergoing colonoscopy without a stool test.
Methods: Our outcomes were advanced lesions (adenomas and/or serrated polyps, including cancer), advanced adenomas, or advanced serrated polyps stratified by location. We examined the prevalence of left- versus right-sided lesions across 3 cohorts.
Results: As compared to colonoscopy (n = 68,645), both FIT+ (n = 584) and mt-sDNA+ (n = 1176) patients had higher proportions of advanced lesions and advanced adenomas on both sides of the colon (P < .001). Mt-sDNA+ patients had significantly higher risks for right-sided advanced serrated polyps (odds ratio [OR] = 3.21; 95% confidence interval [CI], 2.67-3.85; colonoscopy [reference]) and right-sided advanced lesions (OR = 3.13; 95% CI, 2.66-3.68; colonoscopy [reference]) as compared to FIT+ (advanced serrated polyps: OR = 1.38; 95% CI, 0.99-1.99 and advanced lesions: OR = 1.84; 95% CI, 1.43-2.37) or colonoscopy (reference). In our main analysis, the colonoscopy-only group had significantly higher odds of each outcome on the right side than the left side; in comparison, the odds for FIT+ and mt-sDNA+ patients were more evenly distributed throughout the colon.
Conclusions: Our data suggest that FIT+ tests are associated with higher detection of both right- and left-sided advanced adenomas as compared to colonoscopy without a prior stool test. Furthermore, mt-sDNA+ patients had higher proportions of left- and right-sided advanced adenomas and advanced serrated polyps, particularly on the right side.
