Neurology:1型多发性神经纤维瘤病脑干胶质瘤的多学科研究

2017-03-24 MedSci MedSci原创

与偶发的BSGs儿童不同,大多数NF1-BSGs儿童是无症状的,很少有人死于肿瘤并发症。那些需要肿瘤靶向治疗的儿童往往是年龄较大的儿童,并且有局灶性病变,以及有临床进展更快的疾病,相比于那些没有治疗或只进行脑脊液分流的患儿。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章。研究人员旨在定义1型多发性神经纤维瘤病(NF1)儿童脑干胶质瘤(BSGs)的临床和影像学特点。

研究人员在4个NF1转诊中心的133例NF1同时伴有BSGs儿童中进行了一项回顾性横断面研究。BSG是根据放射学标准来确定的。诊断时年龄、肿瘤的位置和外观、临床症状、治疗以及并发的视神经胶质瘤均进行了评估。

BSG诊断的平均年龄为7.2岁,肿瘤最常发生部位为中脑和延髓(66%)。大部分NF1-BSGs儿童是无症状(54%)并且不需要进行治疗(88%)。72名无症状患儿中只有9名儿童接受治疗,因为渐进的肿瘤扩大。相比之下,61例出现临床症状的患儿归因于他们的BSG;这些患者年纪较大,往往有局灶性病变。31例患者因肿瘤接受了治疗,只有14例患者进行了脑脊液分流。接受肿瘤靶向治疗的患儿无进展生存期短于3年,相比于那些没有治疗或只有脑脊液分流的患儿。肿瘤靶向治疗组患儿的总生存率为85%,而在未治疗组或CSF分流组没有报道死亡病例。

与偶发的BSGs儿童不同,大多数NF1-BSGs儿童是无症状的,很少有人死于肿瘤并发症。那些需要肿瘤靶向治疗的儿童往往是年龄较大的儿童,并且有局灶性病变,以及有临床进展更快的疾病,相比于那些没有治疗或只进行脑脊液分流的患儿。

Nat Genet:科学家确定了黑色素瘤第三常见突变基因

众所周知,基因突变在黑色素瘤的发生中扮演着重要的作用,而且已经确定了许多突变的基因和基因组。然而,约30%的黑色素瘤其突变基因仍未清楚。目前,一项新的研究已经确定了存在于大量黑色素瘤中的一组基因突变,并确定了一个主要的突变基因。该研究结果发表于《自然遗传学》杂志上,研究人员来自耶鲁大学,他们希望可通过此发现开发更多针对黑色素瘤的靶向治疗方法。研究人员证实,NF1是黑色素瘤发生过程中主要基因。文中,

BIOL PSYCHIAT:Nf1基因突变与酒精依赖风险相关

科学家们之前曾发现1型神经纤维瘤(NF1)基因与酒精依赖性有关,这种作用可能是通过调节γ-氨基丁酸(γ-GABA)来实现对酒精摄入的影响。最近的一篇文章,来自Scripps研究所的研究人员则发现γ-氨基丁酸这种神经递质能降低焦虑情绪,促进情绪的放松,研究人员指出这一发现将人体Nf1基因的突变,与酒精依赖性风险及严重程度联系在了一起。 这一研究成果公布在8月18日 Biologi
