Lancet Oncology:靶向药物使霍奇金淋巴瘤患者生存期翻倍

第一个应用在霍奇金淋巴瘤30多年的新药brentuximab vedotin(BV)Ⅲ期临床试验结果表明,成年人难治性霍奇金淋巴瘤患者接受干细胞移植后立即给予BV治疗,其无进展生存期是接受安慰剂治疗的两倍(43个月VS 24个月)。这项发表在《The Lancet》杂志上研究结果,将可能改变这个年轻癌症人群的命运。因为他们已经用尽了其他的治疗方案,但依然预后不佳。该研究的第一作者、美国纽约Memo

第一个应用在霍奇金淋巴瘤30多年的新药brentuximab vedotin(BV)Ⅲ期临床试验结果表明,成年人难治性霍奇金淋巴瘤患者接受干细胞移植后立即给予BV治疗,其无进展生存期是接受安慰剂治疗的两倍(43个月VS 24个月)。

这项发表在 The Lancet 杂志上研究结果,将可能改变这个年轻癌症人群的命运。因为他们已经用尽了其他的治疗方案,但依然预后不佳。

该研究的第一作者、美国纽约Memorial Sloan Kettering癌症中心的Craig Moskowitz教授说: “至今没有药物对难治性霍奇金淋巴瘤能够有这样的戏剧性效果。”

霍奇金淋巴瘤是15到35岁的年轻人最常见的血液癌症。大多数病人能够通过化疗或放疗治愈。然而,对于复发或初始治疗无反应的患者,治疗的选择通常是高剂量化疗和自体干细胞移植(ASCT)——一种使用患者的健康干细胞取代被疾病或化疗摧毁细胞治疗方法。大约50%的患者接受这种治疗能够达到治愈的效果,但另一半则只是治标不治本。

BV是连接到一个强大的化疗药物上的抗体,能够靶向霍奇金淋巴瘤细胞中的CD30蛋白以特异性识别并攻击癌细胞。BV靶向结合CD30蛋白,将化疗药物直接导向肿瘤细胞并将其杀死。近年,BV已在50个国家获批准用于复发或难治性霍奇金淋巴瘤的治疗。

在AETHERA Ⅲ期临床试验,Moskowitz和他的同事们希望确定ASCT治疗后早期应用BV是否能够防止疾病进展。他们随机选取了329名18岁以上霍奇金淋巴瘤患者。该群患者为ASCT治疗高危复发或进展的患者,研究人员给予他们每隔3周、16个周期的BV治疗或安慰剂治疗。

在2年随访中,接受BV治疗的患者中有65%没有发生疾病进展,而安慰剂组为45%。Moskowitz博士解释说:“几乎所有接受移植后2年内无疾病进展的患者都能治愈,因为2年后再复发的可能性很小。”

BV一般来说耐受性良好。最常见的副作用是周围神经病变(由于神经损伤导致的四肢麻木或疼痛,BV组 67% vs安慰剂组13%)和中性粒细胞减少(白细胞计数低,35% vs 12%)。

Moskowitz博士说:“最起码来说BV对于低风险霍奇金淋巴瘤患者来说是非常有效的药物,它能够让患者免于进一步传统化疗所造成的细胞破裂而产生的毒素作用。”

ASCO评选癌症治疗50年五大进展

作为今年美国临床肿瘤学会(ASCO)50年庆典的一部分,该学会邀请医生、患者和公众投票选出了过去50年里“现代肿瘤学五大进展。”ASCO主席 Peter Yu称:“所有这些进展都意味着癌症治疗的重大转折,并且改善了无数美国人的生活质量。” 评选出的五项最重要进展如下所示: 1 化疗治愈进展期霍奇金淋巴瘤―1965年,伴随着4种药物联合化疗方案(环磷酰胺、长春新碱、强的松、氮芥,即M

ASH 2014:游离循环DNA测序可检测HL患者的基因失衡

背景:霍奇金淋巴瘤(HL)在所有淋巴瘤中占11-30 %,是青少年和年轻的成年人最常见的一种淋巴瘤。现在,HL大部分是可治愈的,但10 - 15 %的患者会出现化疗不敏感或一线治疗后复发。霍奇金/ Reed-Sternberg (HRS)细胞是经典型霍奇金淋巴瘤(cHL)中的恶性细胞,仅占在cHL活检组织所有细胞的0.1 - 2 %,而其它部分则是由非恶性的免疫细胞混合组成。HRS的稀少严

NEJM:新药有望治疗霍奇金淋巴瘤

PD-1(Programmed Death 1)信号通路是限制T细胞介导的免疫反应的重要检查点。PD-1的两种配体:PD-L1和PD-L2均可以诱导PD-1信号活化并且抑制T细胞的活化和增殖,从而使得肿瘤产生免疫逃逸。临床前研究发现里德-斯泰伯格氏细胞(Reed–Sternberg cells,见于恶性淋巴瘤)可以利用PD-1信号通路逃避免疫系统监视。在典型的Hodgkin’s淋巴瘤中,9p24染

Lancet:霍奇金淋巴瘤传统治疗方案的优化:减少药物可获更好的疗效?

ABVD方案(doxorubicin, bleomycin, vinblastine, and dacarbazine;阿霉素、博来霉素、长春碱、氮烯唑胺)是目前国际上治疗霍奇金淋巴瘤的一线化疗方案也是目前最有效的方案。但由于博来霉素和氮烯唑胺的药物毒性较大,为了验证这两种药物在ABVD方案中的功能,尤其是在早期良性霍奇金淋巴瘤中起到的作用,来自德国的Karolin Behringer与同事们对A

Lancet:ABVD方案是早期霍奇金淋巴瘤的标准方法

为减小ABVD(阿霉素、博来霉素、长春花碱、氮烯咪胺)化疗方案的毒性,一些观点认为氮烯咪胺、博来霉素或两者同时可被舍弃且不影响疗效。而一项非盲、随机的国际临床试验表明,无氮烯咪胺或博来霉素的标准ABVD联合化疗效果不佳。该试验纳入1502名一般情况较好的早期霍奇金淋巴瘤患者,对其进行 2个疗程的ABVD或ABV/AV/AVD治疗,并分析了其5年治疗无失败生存率(FFTF)。研究者德国霍奇金研究组及

ASH 2014:PD-1治疗复发性经典霍奇金淋巴瘤缓解率达66%

2014年第56届美国血液学会年会(ASH)于12月6日-9日在美国旧金山举行。美国血液学会(ASH)是全球最大的关于血液疾病病因及治疗的专业协会,其使命是能过促进血液学的研究、临床护理、教育、培训及宣传而进一步促进对血液、骨髓、免疫、凝血及脉管系统疾病的了解、诊断与防治。 此次年会上,抗癌免疫疗法PD-1/PD-L1抑制剂是一大热点,年会上,Keytruda展现出了治疗血液肿瘤的潜力。根据年会
