项目摘要

DESCRIPTION (provided by applicant): Epidemiologic and scientific research indicates that diet, lifestyle, and other modifiable factors have a significant influence on the risk of developin colorectal cancer (CRC). However, the influence of these interventions on the survival of patients with established CRC remains poorly understood. While randomized clinical trials (RCTs) demonstrate a significant survival advantage for stage III colon cancer patients who receive adjuvant fluorouracil-based chemotherapy, 35-40% of stage III patients receiving current adjuvant chemotherapy still develop cancer recurrence. Patients often seek to understand what, if any diet, lifestyle or supplement will reduce their chances of cancer recurrence. Moreover, how diet and lifestyle influence prognosis may depend, in part, on specific patient characteristics as well as molecular alterations in the tumor. We propose to address these gaps in knowledge within a NCI-sponsored, large, double-blind, placebo- controlled RCT assessing the influence of celecoxib on survival in stage III colon cancer patients who are concurrently receiving standard adjuvant chemotherapy (CALGB 80702). Beyond directly addressing the role of COX inhibition, the trial provides a) two longitudinal prospective assessments of diet, medication usage, and lifestyle habits; b) tumor specimens to examine how exogenous factors interact with specific molecular alterations; c) prospectively collected blood and germline DNA; and d) extensive data on cancer recurrence, mortality, and treated-related toxicity. Since pathologic stage, performance status, post-operative therapy and follow-up are carefully defined in this trial, residual confounding by disease and treatment characteristics should be minimized. In this application, we propose to examine the influence celecoxib and inflammation (Aim 1), and relevant effect modifying pathways (Aim 2) on the risk of cancer recurrence, mortality, and treatment-related toxicity. Each aim extends current knowledge in these areas. Beyond the aforementioned hypotheses, this cohort will allow for the rapid examination of future hypotheses as they emerge. Ultimately, the proposed work seeks to improve our understanding of CRC biology, identify interventions that can improve patient survival, and, with the extensive clinical pathologic, genomic, and biomarker data available for analysis, inform clinicians how to maximally utilize these interventions to improve clinical care.
描述(由申请人提供):流行病学和科学研究表明,饮食、生活方式和其他可改变的因素对结直肠癌(CRC)的发展风险有重大影响。然而,这些干预措施对已确诊的结直肠癌患者生存的影响仍然知之甚少。虽然随机临床试验(RCT)显示接受以氟尿嘧啶为基础的辅助化疗的III期结肠癌患者具有显著的生存优势,但目前接受辅助化疗的III期患者中仍有35%-40%的患者出现癌症复发。患者经常试图了解,如果有任何饮食、生活方式或补充剂,什么可以降低癌症复发的机会。此外,饮食和生活方式对预后的影响可能部分取决于患者的具体特征。 以及肿瘤中的分子变化。我们建议在一项由美国国立卫生研究院赞助的大型、双盲、安慰剂对照的随机对照试验中解决这些知识空白,评估塞来昔布对同时接受标准辅助化疗的III期结肠癌患者生存的影响(CALGB 80702)。除了直接解决COX抑制的作用外,该试验还提供了a)饮食、用药和生活方式习惯的两个纵向前瞻性评估;b)检查外源性因素如何与特定分子改变相互作用的肿瘤标本;c)预期采集的血液和生殖系DNA;以及d)关于癌症复发、死亡率和治疗相关毒性的广泛数据。由于本试验中仔细定义了病理阶段、表现状态、术后治疗和随访,应尽量减少因疾病和治疗特点造成的残留混淆。在这项应用中,我们建议研究塞来昔布与炎症(目标1)的影响,以及相关的效应调节途径(目标2)对癌症复发、死亡率和治疗相关毒性的影响。每个目标都扩展了这些领域的现有知识。除了上述假设之外,这一队列将允许在未来假设出现时对其进行快速检查。最终,拟议的工作旨在提高我们对结直肠癌生物学的理解,确定可以改善患者生存的干预措施,并利用可用于分析的广泛的临床病理、基因组和生物标记物数据,告知临床医生如何最大限度地利用这些干预措施来改善临床护理。
