abstract = {Accurate colorectal cancer (CRC) risk prediction models are
critical for identifying individuals at low and high risk of
developing CRC, as they can then be offered targeted
screening and interventions to address their risks of
developing disease (if they are in a high-risk group) and
avoid unnecessary screening and interventions (if they are
in a low-risk group). As it is likely that thousands of
genetic variants contribute to CRC risk, it is clinically
important to investigate whether these genetic variants can
be used jointly for CRC risk prediction. In this paper, we
derived and compared different approaches to generating
predictive polygenic risk scores (PRS) from genome-wide
association studies (GWASs) including 55,105 CRC-affected
case subjects and 65,079 control subjects of European
ancestry. We built the PRS in three ways, using (1) 140
previously identified and validated CRC loci; (2) SNP
selection based on linkage disequilibrium (LD) clumping
followed by machine-learning approaches; and (3) LDpred, a
Bayesian approach for genome-wide risk prediction. We tested
the PRS in an independent cohort of 101,987 individuals with
1,699 CRC-affected case subjects. The discriminatory
accuracy, calculated by the age- and sex-adjusted area under
the receiver operating characteristics curve (AUC), was
highest for the LDpred-derived PRS (AUC = 0.654) including
nearly 1.2 M genetic variants (the proportion of causal
genetic variants for CRC assumed to be 0.003), whereas the
PRS of the 140 known variants identified from GWASs had the
lowest AUC (AUC = 0.629). Based on the LDpred-derived PRS,
we are able to identify $30\%$ of individuals without a
family history as having risk for CRC similar to those with
a family history of CRC, whereas the PRS based on known GWAS
variants identified only top $10\%$ as having a similar
relative risk. About $90\%$ of these individuals have no
family history and would have been considered average risk
under current screening guidelines, but might benefit from
earlier screening. The developed PRS offers a way for
risk-stratified CRC screening and other targeted
interventions.},
