摘要:

CV2/坍塌反应调节蛋白5抗体相关神经系统副肿瘤综合征不是肿瘤直接侵犯组织或器官,而是肿瘤的远隔效应,免疫介导其发病过程,常可检测到特异性神经元抗体。血清和/或脑脊液CV2/坍塌反应调节蛋白5抗体的检测有助于CV2/坍塌反应调节蛋白5抗体相关神经系统副肿瘤综合征的临床诊断。文章介绍了CV2/坍塌反应调节蛋白5抗体相关神经系统副肿瘤综合征的多样神经系统损害,包括边缘性脑炎、舞蹈症、眼部病变、小脑性共济失调、脊髓病和周围神经病等。CV2/坍塌反应调节蛋白5抗体检测对神经系统副肿瘤综合征的临床诊断较为关键,抗肿瘤及免疫治疗有助于缓解症状、改善预后。文章对CV2/坍塌反应调节蛋白5抗体相关神经系统副肿瘤综合征的研究进行综述,总结归纳其临床特征,以期使更多的临床医生全面地了解该病。文章还讨论了该病现阶段存在的问题,并对近年来一些新的检测和诊断技术在包括CV2/坍塌反应调节蛋白5抗体相关神经系统副肿瘤综合征的应用前景进行了分析和展望。

Abstract: Paraneoplastic neurological syndrome refers to certain malignant tumors that have affected the distant nervous system and caused corresponding dysfunction in the absence of tumor metastasis. Patients with this syndrome produce multiple antibodies, each targeting a different antigen and causing different symptoms and signs. The CV2/collapsin response mediator protein 5 (CRMP5) antibody is a major antibody of this type. It damages the nervous system, which often manifests as limbic encephalitis, chorea, ocular manifestation, cerebellar ataxia, myelopathy, and peripheral neuropathy. Detecting CV2/CRMP5 antibody is crucial for the clinical diagnosis of paraneoplastic neurological syndrome, and anti-tumor and immunological therapies can help to alleviate symptoms and improve prognosis. However, because of the low incidence of this disease, few reports and no reviews have been published about it so far. This article intends to review the research on CV2/CRMP5 antibody-associated paraneoplastic neurological syndrome and summarize its clinical features to help clinicians comprehensively understand the disease. Additionally, this review discusses the current challenges that this disease poses, and the application prospects of new detection and diagnostic techniques in the field of paraneoplastic neurological syndrome, including CV2/CRMP5-associated paraneoplastic neurological syndrome, in recent years.
