Blood:结合初始和诱导后PET,建立更为准确的预测滤泡性淋巴瘤患者预后的模型

2018-03-21 MedSci MedSci原创

根据基线PET计算的总代谢肿瘤体积(TMTV)和诱导结束后的PET(EOI PET)均是成像生物标志物,可提示高肿瘤负荷的滤泡性淋巴瘤患者早期危险分层的前景。近日,Blood上发表一篇文献,Anne Ségolène Cottereau等人结合来159位患者(源于3个前瞻性试验)的这两个数据,建立了一相关模型。对于这159位患者,中位随访64个月。高TMTV(>510cm3)和EOI PET

根据基线PET计算的总代谢肿瘤体积(TMTV)和诱导结束后的PET(EOI PET)均是成像生物标志物,可提示高肿瘤负荷的滤泡性淋巴瘤患者早期危险分层的前景。近日,Blood上发表一篇文献,Anne Ségolène Cottereau等人结合来159位患者(源于3个前瞻性试验)的这两个数据,建立了一相关模型。

对于这159位患者,中位随访64个月。高TMTV(>510cm3)和EOI PET阳性均是独立的、重要的进展风险因素。根据综合情况将159位患者分成3个风险群:无危险因素(102位)、 有1个危险因素(44位)和有2个危险因素(13位),其五年无进展存活率(PFS)分别是67% vs 33%(HR 2.9,95% CI 1.8-4.9)和23%(HR 4.6,95% CI 2.3-9.2);2年PFS分别是90% vs 61%(HR 4.8,95% CI 2.2-10.4)和46%(HR 8.1,95% CI 3.1-21.3)。

总而言之,Anne Ségolène Cottereau等人建立的该模型强化了PET分期的预测意义和反应评估,协助鉴定高进展风险和早期治疗失败的患者亚群。

CLIN CANCER RES:滤泡性淋巴瘤中表达TIGIT的T细胞增多

滤泡性淋巴瘤中浸润的T细胞通常存在功能失调,但是理想的免疫检查点阻断靶点尚未知。分析滤泡性淋巴瘤T细胞亚群共抑制受体表达模式及信号反应可能会有助于发现新的治疗靶点。CLIN CANCER RES近期发表了一篇文章对这一问题进行研究。

Lancet haemat:R-CHOP、放疗、利妥昔单抗维持的序贯疗法治疗晚期滤泡性淋巴瘤的效果和安全性

虽然目前有多种治疗方案,但晚期滤泡性淋巴瘤仍不能被治愈。而且,后诱导治疗的理想顺利和绝对优势也不清楚。现有研究人员对联合放射免疫疗法和化疗后用利妥昔单抗序贯维持治疗的效果和安全性进行评估。本研究为单臂、多中心的II期研究(SWOGS0801),从美国的20个医疗中心招募年满18岁的确诊为III-IV期或II1、II2和II3a期的既往未接受过治疗的滤泡性淋巴瘤患者。受试患者接受5年的治疗计划:R-

NEJM:Obinutuzumab治疗滤泡性淋巴瘤的效果如何?

基于利妥昔单抗的免疫化学疗法改善了滤泡性淋巴瘤患者的疗效。 Obinutuzumab被认为是第二代抗CD20单抗,通过糖基化技术增加了抗体与FcγRIIIa的亲和力。本研究旨在对比利妥昔单抗与Obinutuzumab治疗未经治疗的晚期卵泡淋巴瘤患者的效果。将患者随机分配进行基于obinutuzumab的化疗或基于利妥昔单抗化疗的诱导治疗。接受维持治疗具有反应长达2年的患者在诱导治疗中接受相同的抗体

Blood:FOXP1表达可作为预测利妥昔单抗治疗滤泡性淋巴瘤预后的标志物。

滤泡性淋巴瘤(FL)是一种在临床上和分子上都具有高度异质性的疾病,目前预测主要是依赖于临床检验。研究人员近期发现7个基因(包括EZH2和MEF2B)突变状态的综合,会提高风险分层。研究人员收集基因表达数据来揭示在EZH2和MEF2B突变的病例中的差异性表达的基因。经过筛查,研究人员集中于FOXP1基因,运用免疫组化(IHC)检测763份组织样本FOXP1蛋白的表达量。为了结果的相关性,纳入了一个包

Blood:依鲁替尼治疗复发性或难治性滤泡性淋巴瘤的效果。

大部分滤泡性淋巴瘤患者反复复发,需要不断的治疗。依鲁替尼,bruton酪氨酸激酶抑制剂,已获得批准,用于治疗多种B细胞恶性肿瘤,在临床I期研究中表现出潜在的治疗效果。现研究人员进行II期临床试验,评估依鲁替尼用于复发性滤泡性淋巴瘤的效果。

Lancet haemat:Voxtalisib(XL765)用于滤泡性淋巴瘤患者可获得良好的治疗效果

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
