Use of fecal immunochemical tests for colorectal cancer screening

__Background:__ Despite differences between men and women in incidence of colorectal cancer (CRC) and its precursors, screening programs consistently use the same strategy for both genders. Objective: The objective of this article is to illustrate the effects of gender-tailored screening, including the effects on miss rates of advanced neoplasia (AN). __Methods:__ Participants (age 50–75 years) in a colonoscopy screening program were asked to complete a fecal immunochemical test (FIT) before colonoscopy. Positivity rates, sensitivity and specificity for detection of AN at multiple cut-offs were determined. Absolute numbers of detected and missed AN per 1000 screenees were calculated. __Results:__ In total 1,256 individuals underwent FIT and colonoscopy, 51% male (median age 61 years; IQR 56–66) and 49% female (median age 60 years; IQR 55–65). At all cut-offs men had higher positivity rates than women, ranging from 3.8% to 10.8% versus 3.2% to 4.8%. Sensitivity for AN was higher in me
