Colorectal cancer (CRC) is the third highest cause of cancer death in the United States. Almost 80% of sporadic colorectal cancers have an APC gene mutation. Familial adenomatous polyposis (FAP), a hereditary colon cancer syndrome, is also caused by mutations in APC and affects children as young as 7 years of age. FAP causes hundreds of colonic polyps in affected individuals and a 100% lifetime risk of CRC. In preliminary efforts we have successfully collected hundreds of pre-cancerous colon polyps from individual FAP patients, applied genomic, epigenomic and other multi-omic analyses and begun to elucidate the impact of multiple types of “omic” alterations on precancerous colon polyp evolution toward CRC. We propose to use an integrated and collaborative approach to develop a PreCancer Atlas for colorectal adenocarcinoma using FAP as the disease model. We will: 1) Establish a biospecimen collection pipeline for procurement of longitudinal tissue samples during surveillance colonoscopy and during prophylactic surgical colectomy, including whole blood, serum, normal colonic tissue, colon microbiome, benign pre-cancerous polyps, dysplastic precancerous polyps and colon adenocarcinomas. The material will be used for our own center and will also be available to the Human Tumor Atlas Network (HTAN). Medical records, longitudinal samples and all relevant metadata will also be collected. 2) Establish a center to characterize the tissue samples with state-of-the-art omics and imaging technologies. These include but are not limited to whole genome sequencing, methylation, transcriptome, proteome, cytokine, metabolome, microbiome, and molecular imaging. 3) Establish an analysis core that analyzes and integrates results from -omics, imaging and medical information, builds a spatiotemporal, multidimensional, integrative multi-omics cancer atlas, and develops longitudinal and predictive models for PreCancer biology and progression, as well as data portal and visualization framework. 4) Establish multi-omics technologies on smaller number of samples. 5) Perform a “multiscale deep data analysis” on a large number of samples (57) from a few people and a fewer number of samples (6) from many people. Use this information to guide additional data collection. 6) Identify factors (e.g. germline genetics, microbiome, immune dysfunction) contributing to polyp heterogeneity between and across individuals. Build disease progression models based on these data. 7) Make all biospecimens, information, protocols and software available to the PCA, HTAN and the general scientific community. We expect our efforts will greatly facilitate understanding CRC at its earliest stages and serve as a model for understanding precancerous lesions of other solid tumor malignancies.

结直肠癌（CRC）是美国癌症死亡的第三大原因。几乎80%的 散发性结肠直肠癌具有APC基因突变。家族性腺瘤性息肉病（FAP），一种遗传性 结肠癌综合征也是由APC突变引起的，影响7岁以下的儿童。 FAP导致数百个受影响的个体的结肠息肉和CRC的100%终身风险。初步 经过努力，我们已经成功地从个体FAP患者中收集了数百个癌前结肠息肉， 应用基因组学，表观基因组学和其他多组学分析，并开始阐明多种基因的影响。 癌前结肠息肉向CRC演变的“组学”改变类型。我们建议使用一个 使用FAP开发结直肠腺癌癌前病变图谱的综合和协作方法 作为疾病模型。我们将： 1)建立生物标本采集管道，以便在 监测结肠镜检查和预防性外科结肠切除术期间，包括全血、血清、正常 结肠组织、结肠微生物组、良性癌前息肉、发育不良癌前息肉和结肠 腺癌该材料将用于我们自己的中心，也将提供给人类肿瘤 Atlas Network（HTAN）.还将收集医疗记录、纵向样本和所有相关元数据。 2)建立一个中心，利用最先进的组学和成像技术对组织样本进行表征。 这些包括但不限于全基因组测序、甲基化、转录组、蛋白质组、 细胞因子、代谢组、微生物组和分子成像。 3)建立一个分析核心，分析和整合来自组学、成像和医疗的结果 信息，建立一个时空，多维，综合多组学癌症图谱，并开发 癌前生物学和进展的纵向和预测模型，以及数据门户和 可视化框架 4)在少量样品上建立多组学技术。 5)对来自少数人和更少人的大量样本（57个）进行“多尺度深度数据分析” 样本数量（6）来自许多人。使用此信息指导其他数据收集。 6)确定导致息肉的因素（例如生殖系遗传学、微生物组、免疫功能障碍） 个体之间的异质性。根据这些数据建立疾病进展模型。 7)向常设认证机构、HTAN和一般 科学界。 我们希望我们的努力将大大促进对CRC早期阶段的理解，并成为 了解其他恶性实体瘤的癌前病变。
