Incidence is increasing for both local and advanced disease

?Genetic contributions to CRC: Evaluated large discovery group

50,023 CRC patients and 58089 cancer-free controls 3 large consortia with clinical & genotyping data:

Colon Cancer Family Registry (CCFR), the Colorectal Transdisciplinary (CORECT) Study, and the Genetics and Epidemiology of Colorectal Cancer Consortium (GECCO)

Name of presenter

Analysis

• SNPs coded as 0, 1, or 2 copied of risk allele

• Polygenic risk score

– Weighted, from regression model with 95 SNPS, age, sex, principal components, genotype platform

• Logit for Risk Score vs. CRC

• Stratified by age (< vs. >50) and family h/o CRC

• Self-reported family history

• European descent

Data acquired Limitations Genetic

• 95 CRC-risk-associated SNPs that reached genome-wide significance (p ≤ 5×10-8), in large-scale GWAS

Different polygenic risk score distributions in both early & late

Discovery Cohort Risk Score vs. age of onset and family hx

Discovery Cohort Risk Score vs. age of onset and family hx

Discovery Cohort Risk Score vs. age of onset and cancer location

Conclusion: Early-onset has different genetic risk

• Polygenic risk score (per standard deviation)

– stronger for early-onset: 4th v 1st quartile risk

• 3.7-fold (95% CI: 3.28, 4.24) for early-onset

• 2.9-fold (95% CI: 2.80, 3.04) for late-onset CRC

– Strongest without a first-degree family history (p<0.01)

• 4th v 1st Q: 4.3-fold (3.61, 5.01) early; 2.9 (2.70, 3.00).
