Colorectal cancer (CRC) is a biologically heterogeneous disease. To characterize its mutational profile, we conduct targeted sequencing of 205 genes for 2,105 CRC cases with survival data. Our data shows several findings in addition to enhancing the existing knowledge CRC. We identify PRKCI, SPZ1, MUTYH, MAP2K4, FETUB, and TGFBR2 as additional significantly mutated find that among hypermutated tumors, an increased mutation burden associated improved CRC-specific (HR = 0.42, 95% CI:...
Abstract Carriers of germline biallelic pathogenic variants in the MUTYH gene have a high risk colorectal cancer. We test 5649 cancers to evaluate discriminatory potential tumor mutational signature specific for identifying carriers and classifying uncertain clinical significance (VUS). Using matched targeted multi-gene panel approach, our classifier identifies all known non-carriers an independent set 3019 (accuracy = 100% (95% confidence interval 99.87–100%)). All monoallelic are...
Abstract Protective associations of fruits, vegetables, and fiber intake with colorectal cancer risk have been shown in many, but not all epidemiologic studies. One possible reason for study heterogeneity is that dietary factors may distinct effects by molecular subtypes. Here, we investigate the association fruit, four well-established subtypes separately combination. Nine observational studies including 9,592 cases microsatellite instability (MSI), CpG island methylator phenotype (CIMP),...

Abstract Polygenic risk scores (PRS) have great potential to guide precision colorectal cancer (CRC) prevention by identifying those at higher undertake targeted screening. However, current PRS using European ancestry data sub-optimal performance in non-European populations, limiting their utility among these populations. Towards addressing this deficiency, we expand development for CRC incorporating Asian (21,731 cases; 47,444 controls) into training datasets (78,473 107,143 controls). The...
Abstract Background Waist circumference (WC) and its allometric counterpart, “a body shape index” (ABSI), are risk factors for colorectal cancer (CRC); however, it is uncertain whether associations with these measurements limited to specific molecular subtypes of the disease. Methods Data from 2,772 CRC cases 3,521 controls were pooled four cohort studies within Genetics Epidemiology Colorectal Cancer Consortium. Four markers (BRAF mutation, KRAS CpG island methylator phenotype,...
Abstract Background Deep Learning (DL) has emerged as a powerful tool to predict genetic biomarkers directly from digitized Hematoxylin and Eosin (H&E) slides in colorectal cancer (CRC). However, few studies have systematically investigated the predictability of beyond routinely available alterations such microsatellite instability (MSI), BRAF KRAS mutations. Methods Our primary dataset comprised H&E CRC tumors across five cohorts totaling 1,376 patients who underwent comprehensive...
Artificial intelligence (AI) has transformed digital pathology by enabling biomarker prediction from high-resolution whole slide images (WSIs). However, current methods are computationally inefficient, processing thousands of redundant tiles per WSI and requiring complex aggregator models. We introduce EAGLE (Efficient Approach for Guided Local Examination), a deep learning framework that emulates pathologists selectively analyzing informative regions. incorporates two foundation models:...
