PROJECT SUMMARY/ABSTRACT This application is being submitted in response to the Notice of Special Interest (NOSI) identified as NOT- CA-22-057. A better understanding of lymphoma biology has aided in predicting therapy responses and outcomes; however, this cannot entirely explain differences in vulnerable populations. In Latin America (LATAM), lymphotropic viruses (i.e., HTLV-1, EBV) are a common cause of aggressive non-Hodgkin lymphoma (NHL) subtypes and are associated to poor outcomes. The Lymphoma Epidemiology of Outcomes (LEO) cohort study is the largest prospective cohort of NHL survivors in the world. However, only few patients with virally-driven NHL have been enrolled, therefore, limiting the advancement on the knowledge of these rare but fatal diseases. Both EBV- and HTLV-1-associated lymphomas disproportionately affect racial/ethnic underserved populations in LATAM and the U.S., with advancements in the field being precluded by the low numbers of cases seen in the U.S. The overall goals of this supplemental application are to directly extent our ongoing research by expanding the number of NHL subtypes currently registered; improve and develop population-specific prognostic models; advance the current knowledge on rare lymphomas by directly studying NHL subtypes prevalent in LATAM; expand the racial/ethnic diversity of NHL research by recruiting a large number of Hispanic and Native Indigenous patients; and introduce immunogenomics to the study of NHL in LATAM. In this proposal, we aim to establish a partnership between the LEO cohort study and the Latin American Group of Lymphoproliferative Disorders (GELL group). Considering the award period for this supplemental grant, the estimated number of virally-driven NHL subtypes seen per center, and our prior experience collaborating with these centers, we propose to work with two cancer hospitals in Lima, Peru, the Hospital Edgardo Rebagliati and the Instituto Nacional de Enfermedades Neoplasicas (INEN), the two largest cancer hospitals in Peru. Over the next year we propose to: aim 1, develop a clinicopathological database to capture data of 80 HTLV-1/ATLL and 80 EBV+ DLBCL, NOS patients followed for long-term prognosis and survivorship; aim 2, build the resource to investigate the tumor mutational burden and gene expression signature of these viral-associated NHL using DNA and RNA sequencing; and aim 3, develop novel prognostication models by examining the relative contribution of the different clinical variables and genomic data on lymphoma outcomes using principal component and machine learning approach. Drs. Flowers and Malpica have additional resources to perform sequencing for aim 2. This approach will enhance the current knowledge of virally-driven aggressive NHL subtypes and dramatically expand the number of NHL patients characterized with clinical data and genomics beyond LEO. In conclusion, this proposal addresses an exceptional opportunity to research these unique entities in a collaboration across 10 academic institutions in the U.S. and Peru. This work leverages data and samples from >12,000 NHL patients already accrued by the LEO study and will generate novel data for these rare but fatal lymphomas that disproportionately affects vulnerable populations in the U.S. and LATAM.

项目概要/摘要 本申请是为了响应被确定为 NOT- 的特殊利益通知 (NOSI) 而提交的 CA-22-057。更好地了解淋巴瘤生物学有助于预测治疗反应和结果； 然而，这并不能完全解释弱势群体之间的差异。在拉丁美洲 (LATAM)，嗜淋巴细胞 病毒（即 HTLV-1、EBV）是侵袭性非霍奇金淋巴瘤 (NHL) 亚型的常见原因，并且 与不良结果相关。淋巴瘤流行病学结果 (LEO) 队列研究是规模最大的 世界上 NHL 幸存者的前瞻性队列。然而，只有少数病毒驱动的 NHL 患者得到了治疗。 因此，入学限制了这些罕见但致命疾病知识的进步。 EBV- 和 HTLV-1 相关淋巴瘤不成比例地影响拉丁美洲和拉丁美洲服务不足的种族/族裔人群 美国，由于美国病例数量较少，该领域的进展受到阻碍 此补充应用程序的目标是通过扩大 NHL 的数量来直接扩展我们正在进行的研究 当前注册的子类型；改进和开发特定人群的预后模型；推进当前的 通过直接研究拉丁美洲流行的 NHL 亚型来了解罕见淋巴瘤；扩大种族/民族 通过招募大量西班牙裔和原住民患者来实现 NHL 研究的多样性；并介绍 免疫基因组学在拉丁美洲 NHL 研究中的应用。在本提案中，我们的目标是在以下机构之间建立伙伴关系： LEO 队列研究和拉丁美洲淋巴增殖性疾病组（GELL 组）。考虑到 该补充补助金的授予期限、每个中心发现的病毒驱动的 NHL 亚型的估计数量、 以及我们之前与这些中心合作的经验，我们建议与利马的两家癌症医院合作， 秘鲁，埃德加多·雷巴利亚蒂医院 (Hospital Edgardo Rebagliati) 和国家肿瘤研究所 (INEN)，这两家医院 秘鲁最大的癌症医院。明年我们建议：目标 1，开发临床病理学数据库 捕获 80 名 HTLV-1/ATLL 和 80 名 EBV+ DLBCL、NOS 患者的数据，跟踪其长期预后和 生存；目标 2，建立研究肿瘤突变负荷和基因表达特征的资源 使用 DNA 和 RNA 测序对这些病毒相关的 NHL 进行分析；目标 3，开发新颖的预测模型 通过检查不同临床变量和基因组数据对淋巴瘤结果的相对贡献 使用主成分和机器学习方法。博士。 Flowers 和 Malpica 有额外的资源 为目标 2 进行测序。这种方法将增强对病毒驱动的侵袭性 NHL 的当前了解 亚型并显着增加具有临床数据和基因组学特征的 NHL 患者数量 超越近地轨道。总之，该提案提供了研究这些独特实体的绝佳机会 美国和秘鲁 10 个学术机构合作。这项工作利用了来自 LEO 研究已经收集了超过 12,000 名 NHL 患者，将为这些罕见但致命的患者生成新数据 淋巴瘤对美国和拉丁美洲的弱势群体影响尤为严重。
