Charting Colon Cancer’s Molecular Axes via an Integrated Multi-Omic Atlas and AI-Driven Histopathology

[vc_section el_class="container mx-auto align-items-center circle--pattern" css=".vc_custom_1648956589196{padding-top: 3rem !important;}"][vc_row el_class="pb-5"][vc_column][vc_wp_custommenu nav_menu="6"][uoh_breadcrumb_component automatic_breadcrumb="true"][uoh_title_component title_dropdown="big" title_decorator="true"]{{title}}[/uoh_title_component][vc_column_text css=""]Chile is facing one of the steepest increases in Colorectal cancer (CRC) incidence and mortality in the Southern Cone, with the greatest surge occurring in adults ≤ 50 years. Incidence is lowest in the far north and increases toward the south-central regions, mirroring a gradient in Aymara-Mapuche Native-American ancestry, an axis largely absent from the European reference cohorts that guide modern precision oncology. To fill this gap, we propose a four-year project to create the first Chile-specific, multi-omic and histopathological atlas of CRC and to explore ancestry-aware, AI-assisted diagnostics. Rationale and Hypothesis. We hypothesise that Chilean CRC shows (i) unique, ancestry-driven molecular patterns that differ from European tumors; (ii) AI models can detect these patterns directly on routine whole-slide images, and (iii) they shape distinct evolutionary paths in early- versus late-onset disease. Specific objectives. Molecular landscape & heterogeneity: Produce single-gland long-read WGS, methylome, and transcriptome profiles for 100 tumors (30 early-onset, 70 late-onset; ≥30× coverage, ≥50 % purity). Ancestry impact: Phase somatic alterations by local ancestry and contrast their frequencies with European CRC genomes (TCGA, PCAWG). AI-enhanced histopathology: Train and externally validate multi-instance-learning (MIL) models that predict microsatellite instability, driver mutations, and whole-genome doubling from matched WSIs, targeting AUC ≥ 0.80 (pilot: AUC ≥ 0.85 for whole-genome doubling on TCGA WSIs). Evolutionary trajectories: Multi-region sequence early-onset and late-onset tumors, reconstruct their clonal phylogenies, and contrast the resulting evolutionary patterns between the two age groups. Team capacity & resources. Computational biologist Alex Di Genova (genomics & AI), pathologist Juan Carlos Araya (digital pathology), and gastro-immunologist Tamara Pérez-Jeldres (clinical phenotyping) have prospective access to >220 new CRC resections and >1,800 registry entries each year. A biobank already houses 100 well-annotated tumour specimens from hospitals in Santiago and the O’Higgins Region, ready for immediate sequencing and imaging. As a team we are delivering important results as (i) the generation of the first telomere-to-telomere Chilean genome, establishing a population-specific reference; (ii) sequenced >270 high-coverage whole genomes of chileans individuals (70 healthy donors, 120 hereditary-breast-cancer cases, 80 primary gallbladder tumors); iii) built the first multi-omic atlas of gallbladder cancer by integrating our data with Korean (n = 94) and Indian (n = 64) cohorts, uncovering a Chile-enriched proliferative phenotype; and (iv) developed CRAB-MIL, a weakly supervised deep-learning framework that predicts whole-genome doubling from routine H&E slides with an AUC > 0.85 and provides attention maps for interpretability. These accomplishments demonstrate our ability to generate, integrate, and clinically interpret large-scale genomic and AI datasets—capabilities directly transferable to Chilean CRC. International collaborators Anaïs Baudot (Marseille) and Luis Zapata (Institute of Cancer Research, London) further contribute multi-omic network analysis and evolutionary-genomics expertise, respectively. Interdisciplinary workflow. Clinical phenotyping, computational histopathology, PromethION sequencing, and Nextflow harmonisation feed ancestry-aware genomic analyses; attention-based models are fine-tuned on TCGA and Chilean WSIs; computational, pathology, and gastroenterology teams jointly review outputs to prioritise clinically relevant signals. All variant calls, methylomes, expression matrices, AI prediction, and metadata will be released through an open and intuitive TumorMap portal. Expected Outcomes and Impact. The project will (i) reveal population-specific drivers and mutational processes, (ii) quantify the frequency of clinically actionable biomarkers originally identified in Europeans, (iii) deliver image-based tools that offer low-cost, molecular stratification and heterogeneity scoring, and (iv) provide a high-resolution evolutionary framework for EO versus LO CRC. Collectively, these data will offer the first high-resolution portrait of the Chilean CRC and lay the groundwork for ancestry-aware screening, diagnostic, and treatment strategies.[/vc_column_text][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649209804184{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5"][vc_row el_class="container mx-auto align-items-center p-md-0 pt-5"][vc_column el_class="p-0"][/vc_column][/vc_row][/vc_section][vc_section css=".vc_custom_1649210787516{background-color: #f6faff !important;}" el_class="p-md-0 pt-md-5 pb-md-5"][vc_row el_class="container mx-auto align-items-center"][vc_column][/vc_column][/vc_row][/vc_section]
