Annual Meeting of the International Primary CNS Lymphoma Collaborative Group (IPCG)

项目摘要 原发性中枢神经系统淋巴瘤（PCNSL）是一种非霍奇金淋巴瘤的淋巴结变异， 非霍奇金淋巴瘤（NHL）是局限于脑、脊髓、软脑膜和眼睛的淋巴瘤。诊断 PCNSL的治疗方法与应用于其他形式的 NHL。国际原发性中枢神经系统淋巴瘤协作组（IPCG） 由来自多个学科的专家组成，致力于PCNSL的研究。IPCG持有 在美国血液学会会议上举行的年度科学会议上， 讨论了与PCNSL相关的研究课题。选择有关所讨论专题的专家 每年由一个执行委员会主持科学会议。这些会议导致 对该领域产生积极影响的多个合作项目， 发表在同行评议的文献中。IPCG年度会议是一个重要的论坛， 产生新的想法和方法来治疗这种独特而罕见的淋巴瘤。2021年 会议主题是原发性玻璃体视网膜淋巴瘤（PVRL）：诊断和 管理PVRL是罕见的，没有标准的指南来管理这种疾病。 IPCG先前发表了大量PVRL患者的结果（Grimm et al， Ann Oncol 2007）。从那时起，PVRL的诊断和研究取得了进展 证明靶向药物的功效。因此，IPCG成员非常有兴趣 召开PVRL诊断和治疗研讨会。

Project Summary Primary central nervous system lymphoma (PCNSL) is an extranodal variant of non-Hodgkin lymphoma (NHL) that is confined to the brain, spinal cord, leptomeninges and eye. The diagnostic and therapeutic approaches to PCNSL are different from those that are applied to other forms of NHL. The International Primary Central Nervous System Lymphoma Collaborative Group (IPCG) consists of specialists from multiple disciplines dedicated to the study of PCNSL. The IPCG holds an annual scientific conference at the American Society of Hematology meeting in which various research topics related to PCNSL are discussed. Experts on the topic under discussion are selected each year by an executive committee to chair the scientific conference. These meetings have led to multiple collaborative projects that have positively impacted the field and that have been published in the peer reviewed literature. The annual IPCG meeting is a critical forum for generating new ideas and approaches to this unique and rare form of lymphoma. The 2021 conference topic is Primary Vitreoretinal Lymphoma (PVRL): Advances in Diagnostics and Management. PVRL is rare and there are no standard guidelines for management of this disease. The IPCG previously published results from a large series of patients with PVRL (Grimm et al, Ann Oncol 2007). Since then, there has been development in the diagnostics of PVRL and studies demonstrating efficacy of targeted agents. Accordingly, it is of great interest to IPCG members to have a symposium of diagnosis and treatment of PVRL.
