Study Citation Study Population Uptake of Gynecologic Screening Before Genetic Counseling and Testing Uptake of Gynecologic Screening After Receipt of Genetic Test Results Length of Follow-up Comments 
Claes et al. (2005)1,a [32]Carriers (n = 7)Not reportedTVUS 1 yOne noncarrier reported undergoing TVUS for a previous endometrial problem, while three noncarriers reported undergoing the procedure for preventive reasons.
– Carriers 86% (6/7)
Noncarriers (n = 16)
– Noncarriers 27% (4/15)
Collins et al. (2007)1,a [29]Carriers (n = 13)Not reportedTVUS 3 yTwo of four carriers had an RRH/RRSO by the 3-year follow-up assessment.
– Carriers 69% (9/13)
– Noncarriers 6% (2/32)
Noncarriers (n = 32)ES
– Carriers 54% (7/13)
– Noncarriers 3% (1/32)
Yurgelun et al. (2012): Cohort 12,a [56]77 at risk of LS-associated EC; 45 carriers; 19 no genetic testing but LS-associated family history75% (58/77) engaged in EC screening or EC risk-reduction intervention; 42 underwent annual TVUS and/or ES; 16 underwent RRHNot reportedN/A
Yurgelun et al. (2012): Cohort 21,a [56]40 women at clinical risk of LS65% (26/40) adhered to EC screening or risk reduction; 6 underwent RRH; 13 underwent annual ES and/or TVUS; 6 had not reached recommended screening ageCarriers: 100% (n = 16) adhered to EC screening or risk-reducing strategies; 4 underwent pretest RRH; 5 underwent RRH; 5 underwent EC screening (TVUS and/or ES); 2 had not reached recommended screening age1 y
Carriers (n = 16)
Noncarriers (n = 9); 14 indeterminate results; 1 variant of uncertain significanceNoncarriers: 11% (1/9) underwent EC screening; 11% (1/9) underwent RRH

EC = endometrial cancer; ES = endometrial sampling; RRH = risk-reducing total abdominal hysterectomy; RRSO = risk-reducing salpingo-oophorectomy; TVUS = transvaginal ultrasound.
Noncarrier(s) = negative for known mutation in family.
1Prospective study design.
2Retrospective study design.
