2015年5月30日,据BBC新闻报道的一项新近研究称,肺癌治疗可使一些患者的生存期加倍,实属里程碑式的新发现。


        
Nivolumab可使隐藏与人体正常防御系统之下的癌细胞无所遁形,让其接受人体免疫系统的自发处理。
        
该结果来自纳入582例癌症患者的研究结论,在美国临床肿瘤学会中发布,被描述为“给患者带来新希望”的研究进展。
        
肺癌是常见癌症种类中致死率最高的癌症类型,每年死于肺癌的人数高达1600万人口。
        
之所以难以治疗,是因为当患者被确诊为肺癌时,已经处于晚期。同时,很多患者具有吸烟史,这使得很多患者不适合立即手术。
        
自然防御
        
免疫系统能够自发的对抗感染,也可以抗击部分异常的机体组织或细胞,诸如癌症。
        
然而,肿瘤本身也颇具灵性,常常与人体自身的防御系统“躲猫猫”,使其难以察觉。
        
它们的狡猾之处还在于,能够产生一种称为PD-L1的蛋白,它可将人体免疫体统的靶点移花接木。
        
Nivolumab是一种称为“抑制剂”的有效治疗药物,由制药公司生产。
        
该药具备扭转癌症细胞转移靶点的功能,令癌细胞失去保护,在免疫系统中无所遁形。
        
该项研究是在美国与欧洲进行的,受试者均为肺癌患者,且对现有疗法耐受的人群。
        
此期的癌症患者,若接受常规治疗,仅有9.4个月的生存期。但当他们接受了Nivolumab治疗后,平均生存期提高到了12.2个月。
        
然而,一些患者对该药的效果持怀疑态度。那些能够产生高水平PD-L1的肿瘤患者有些人还能存活到19.4个月。
        
里程碑
        
呈现这些数据的第一作者来自西班牙,他认为这一研究结果为肺癌患者带来了里程碑式的福音。他表示,“Nivolumab是首个PD-L1受体,在三期临床试验中显示出提高患者生存率的显著价值。”
        
这确实是一个令人振奋的消息。来自英国伦敦大学癌症研究院的马汀医生表示,“该药将在如何治疗肿瘤领域成为范式转化。”
        
他还表示,当患者接受化疗失败后,当前的生存率是惨不忍睹的。
        
但通过对免疫回应的观察来评估,对疾病控制确实起到了较好的推迟作用,这对癌症患者来讲本身就是一个好消息,有望出现戏剧性的转变。
        
虽然,就目前来看,该药价格高昂且普及率较低,但其里程碑式的研究成果并未收太大影响,但我们还应努力扩大肺癌患者收益面作出努力。

PLoS One:前列腺特异膜抗原(PSMA)可作为肺癌治疗潜在的新靶标

背景:在非前列腺癌肿瘤新生血管内皮细胞(NCEs)中发现有前列腺特异膜抗原(PSMA),并后者可能成为抗肿瘤治疗最有前途的靶标。本研究以PSMA值作为肺癌治疗潜在的新靶标,研究PSMA在非小细胞肺癌(NSCLC)和小细胞肺癌(SCLC)组织中的表达,以及在当前研究中其与临床病理学的关系。方法:共有150个肺癌患者肺组织样本的PSMA表达用免疫组织化学检测,最后使用单变量和多变量统计数据进行分析。结

NEJM:肺癌支气管基因组分类的诊断评价

背景:支气管镜检查通常不能作为肺部病变并疑似肺癌的患者的检查。虽然很多病变是良性的,但这通常会导致更多的侵入性的检测。我们试图验证支气管气道基因表达分类,来提高支气管镜检查的诊断性能。    方法:研究人员从28个中心招募了正在进行纤维支气管镜检同时有有吸烟个人史的疑似肺癌的患者进行了两个多中心的前瞻性研究(AEGIS-1和AEGIS-2)。一种基因表达分类在上皮细胞

Lancet:I期NSCLC-立体定向放疗效果优于手术治疗

根据德克萨斯大学MD安德森癌症中心的一项Ⅲ期随机国际性研究结果,可手术治疗分期中Ⅰ期的非小细胞肺癌(NSCLC)患者接受立体定向消融治疗(SABR)将能取得更好的整体存活率,优于当前的医学治疗标准——开刀手术。该项研究是首个对比SABR和手术治疗的临床随机试验,研究结果发表在最新一期The Lancet杂志上。“我们可以第一次这么说,至少在两种治疗方法同样有效,但对于这些患者来说SABR似乎具有更

目的:该研究的目的在于收集一种通过革新且与性别相关的宣传教育手册的有效性,该手册采用情感激励手段及其相关因素用于鼓励肺癌病人戒烟。方式:该研究为定性、描述性研究。实验在加拿大六个城市进行。参与人员为30个近期戒烟的肺癌患者。我们使用宣传手册分别对男性和女性患者用交谈和图片教育进行宣传教育,强调家庭成员的作用和他们的性别反思,使他们具有戒烟的勇气和信心,起到激励的作用。我们分别给男性和女性肺癌患者予

美国医院肺癌放疗全新技术

什么是放疗治疗?  放疗治疗是一个医疗过程,用高能量的放射线杀死肿瘤细胞,并缩小肿瘤。  放疗是如何起作用的?  高能射线破坏细胞中的DNA,导致他们死亡或停止分裂。因此癌细胞比正常细胞分裂更快,他们更加容易被破坏,更易受到攻击。健康细胞也会受到影响,但是能够更好的修复这种破坏。  什么时候适合使用放疗?  小细胞肺癌和非小细胞肺癌经常用放疗进行治疗,放疗经常与化疗,或外科手术,或者两者一起,联合
