PROJECT SUMMARY Pancreatic cancer is the 3rd leading cause of cancer death in the United States. The high mortality of pancreatic ductal adenocarcinoma (PDAC) is largely a consequence of diagnosis at an advanced stage when the tumor is no longer treatable for cure. Currently, asymptomatic screening for PDAC is not recommended for the general population, with screening pursued only for a small subset of patients with pancreatic cystic lesions or strong genetic risk for PDAC. Even when cancer is identified early, patients can have rapid recurrence after surgical resection, most often with liver metastases. To improve outcomes for patients with PDAC, a number of important advancements are urgently needed, including improved risk assessment to identify those at elevated risk for PDAC, new non-invasive biomarkers to select individuals for intensive imaging surveillance, and better strategies to identify those with localized tumors who are at risk for rapid recurrence after surgical resection. In the current proposal, we directly address these critical areas of need, focusing on: (a) machine learning models for risk assessment from electronic medical record data (Aim 1), (b) development of non-invasive biomarkers from stool and computed tomography (CT) imaging that measure metabolic alterations caused by early PDAC (Aim 2), and (c) characterization of CT imaging and circulating cell-free DNA methylation patterns to predict presence of occult metastases at the time of surgical resection (Aim 3). Furthermore, we will collect and make available clinical data, blood samples, stool samples, imaging studies, and tumor tissue from multiple patient populations critical to PDAC early detection research, including those with early-stage PDAC, chronic pancreatitis, genetic PDAC risk, pancreatic cystic lesions, and non-cancer controls (Aim 4). To accomplish the proposed work, we have assembled a highly experienced and collaborative team that is fully committed to working together and with other Pancreatic Cancer Detection Consortium units. Thus, we will leverage cutting- edge machine learning approaches, develop multiple innovative, non-invasive biomarker technologies, and collect a large array of data and clinical samples for collaborative activities within and outside the Pancreatic Cancer Detection Consortium. With a highly dedicated expert team and clear scientific plan, we expect to achieve our near-term goal of reducing pancreatic cancer mortality by finding PDAC earlier and treating it more effectively for cure.

项目总结 胰腺癌是美国癌症死亡的第三大原因。儿童的高死亡率 胰腺导管腺癌(PDAC)在很大程度上是晚期诊断的结果，当 这种肿瘤不再是可以治愈的。目前，不建议对PDAC进行无症状筛查 普通人群，只对一小部分胰腺囊性病变患者进行筛查 或对PDAC有很强的遗传风险。即使癌症被及早发现，患者也可能在术后迅速复发 外科手术切除，最常合并肝转移。为了改善PDAC患者的预后，许多 迫切需要重要的进展，包括改进风险评估，以确定那些处于高危状态的人 PDAC的风险，新的非侵入性生物标记物，用于选择个人进行密集成像监视，以及更好的 确定那些有手术切除后快速复发风险的局部肿瘤患者的策略。在……里面 在目前的提案中，我们直接解决了这些关键领域的需求，重点是：(A)机器学习模型 根据电子病历数据进行风险评估(目标1)，(B)开发非侵入性生物标记物 来自大便和计算机断层扫描(CT)成像，测量早期PDAC引起的代谢变化 (目标2)和(C)CT成像和循环中无细胞DNA甲基化模式的特征以预测 手术切除时存在隐匿性转移(目标3)。此外，我们还将收集和制作 多名患者的临床资料、血样、粪便样本、影像检查和肿瘤组织 对PDAC早期检测研究至关重要的人群，包括那些患有早期PDAC、慢性 胰腺炎、遗传性PDAC风险、胰腺囊性病变和非癌症对照(目标4)。要完成以下任务 我们已经组建了一支经验丰富、协作能力强的团队，全力致力于 与其他胰腺癌检测联盟单位合作。因此，我们将利用削减- 边缘机器学习方法，开发多种创新的、非侵入性的生物标记技术，以及 为胰腺内外的协作活动收集大量数据和临床样本 癌症检测联盟。凭借高度敬业的专家团队和明确的科学计划，我们希望 通过更早地发现PDAC并对其进行更多治疗，实现降低胰腺癌死亡率的近期目标 有效地治愈了。
