复发性/难治性淋巴瘤或慢性淋巴系白血病患者预后差。靶向多种类型的PI3K(如mTOR)的治疗方式或可增强抗肿瘤活性。现有研究人员对voxtalisib(XL765或SAR245409)——一种fan-PI3K/mTOR抑制剂——用于复发性/难治性淋巴瘤或慢性淋巴细胞白血病/小淋巴细胞白血病患者的疗效和安全性进行评估。研究人员在多个国家的30个肿瘤诊所进行一非随机的开放性临床2期试验,招募年满18岁

复发性/难治性淋巴瘤或慢性淋巴系白血病患者预后差。靶向多种类型的PI3K(如mTOR)的治疗方式或可增强抗肿瘤活性。现有研究人员对voxtalisib(XL765或SAR245409)——一种fan-PI3K/mTOR抑制剂——用于复发性/难治性淋巴瘤或慢性淋巴细胞白血病/小淋巴细胞白血病患者的疗效和安全性进行评估。

研究人员在多个国家的30个肿瘤诊所进行一非随机的开放性临床2期试验,招募年满18岁的EGOG表现状态评分≤2分的复发性/难治性套细胞淋巴瘤、滤泡性淋巴瘤、弥漫性大B细胞淋巴瘤或慢性淋巴细胞白血病/小淋巴细胞白血病患者,予以voxtalisib 50mg 2次/日 口服,28天一疗程,持续用药直到病程进展或出现不可耐受的毒副作用。主要评估节点:每个特异性疾病队列中获得总体缓解(包括完全缓解和部分缓解)的患者比例。所有患者接受4周以上的治疗。

2011年10月19日-2013年7月24日,共招募167位患者(套细胞淋巴瘤 42位、滤泡性淋巴瘤 47位、弥漫性大B细胞淋巴瘤 42位、慢性淋巴细胞白血病/小淋巴细胞白血病 36位)。淋巴瘤患者既往抗癌治疗中位次数是3次(IQR 2-4),慢性淋巴细胞白血病/小淋巴细胞白血病患者的是4次(2-5)。164位患者可评估疗效,其中30位(18.3%)获得总体缓解(22位部分缓解、8位完全缓解):46位滤泡性淋巴瘤患者中有19位(41.3%)、42位套细胞淋巴瘤患者中有5位(11.9%)、41位弥漫性大B细胞淋巴瘤患者中有2位(4.9%)、35位白血病患者中有4位(11.4%)。安全状况与既往voxtalisib相关研究一致。最常见的副反应有腹泻(35%[59/167])、疲劳(32%)、恶心(27%)、发热(26%)、咳嗽(24%)和纳差(21%)。最常见的3级及以上副反应是贫血(12%)、肺炎(8%)和血小板减少(8%)。167位患者中发生97例(58.1%)重度副反应。

Voxtalisib 50mg每日口服两次,安全性可耐受,用于滤泡性淋巴瘤患者可获得良好疗效,但对于套细胞淋巴瘤、弥漫性大B细胞淋巴瘤或慢性淋巴细胞白血病/小淋巴细胞白血病患者则效果欠佳。

《流式细胞学在非霍奇金淋巴瘤诊断中的应用专家共识(2016年版)》解读

中国抗癌协会血液肿瘤专业委员会为了提高国内非霍奇金淋巴瘤(NHL)的诊断和治疗监测水平,促进多学科合作在淋巴瘤诊疗中的发展,组织专家在国内首次制订了《流式细胞学在非霍奇金淋巴瘤诊断中的应用专家共识》。共识从FCM在NHL诊断中的地位和作用入手,详细介绍了FCM诊断NHL的流程、方法以及质量控制等内容。本文着重从FCM技术用于淋巴瘤免疫分型的分析思路及不同病种的免疫表型特点对共识进行解读。

Blood:国际SCHOLAR-1研究结果:难治性弥漫性大B细胞淋巴瘤的预后情况。

弥漫性大B细胞淋巴瘤(DLBCL)是非霍奇金淋巴瘤最常见的亚型。虽然一线5年生存率有60%-70%,但高达50%的患者会进展成难治性或治疗后复发。已发表的对难治性DLBCL患者的大规模预后数据分析有限。

Int J Cancer:终生饮酒是否与非霍奇金淋巴瘤风险相关?

先前的队列研究报告中,酒精摄入和非霍奇金淋巴瘤(NHL)风险的证据不一致,这些证据大多是基于研究对象登记的酒精摄入量而得出的。

【1】Int J Cancer:终生饮酒是否与非霍奇金淋巴瘤风险相关?先前的队列研究报告中,酒精摄入和非霍奇金淋巴瘤(NHL)风险的证据不一致,这些证据大多是基于研究对象登记的酒精摄入量而得出的。来自澳大利亚的研究人员从饮酒者20岁就开始测量他们的酒精摄入量。基于墨尔本协作队列研究的37990名年龄在40-69岁的饮料具体消费频率和数量数据,研究人员计算了饮酒者从20岁开始10年内的平时饮酒量。研

CLIN CANCER RES:非霍奇金淋巴瘤和霍奇金淋巴瘤过表达BCLW

B细胞淋巴瘤在进展过程中必然会出现凋亡抵抗。最近的研究发现BCLW,一个抗凋亡BCL2家族成员,过去认为仅对精子生成过程有影响,在弥漫大B淋巴瘤和Burkitt淋巴瘤中过表达。CLIN CANCER RES近期发表了一篇文章,研究6种不同B细胞淋巴瘤BCLW和其他抗凋亡BCL2家族成员的表达,以进一步研究BCLW对B细胞淋巴瘤的作用以及其对BCL2抑制剂耐药的影响。

ASH 2017:国产新药BGB-3111在惰性和侵袭性非霍奇金淋巴瘤患者中的安全性和有效性研究

B细胞受体(BCR)信号通路参与调节B细胞的增殖、迁移和粘附,布鲁顿酪氨酸激酶(BTK)在BCR信号通路中发挥至关重要的作用。多种类型非霍奇金淋巴瘤(NHL)已将BCR信号通路作为靶向治疗靶点。BGB-3111是一种不可逆的BTK抑制剂,具有高效性及高度特异性,对BTK具有高度选择性,而对其他TEC和EGFR家族激酶选择性较弱,证实其具有良好的药代动力学和药效动力学特性。1期临床试验表明患者接受1
