Gut:影像以及血浆生物标志物用于转移性结肠癌治疗效果的评估

2017-08-09 zhangfan MedSci原创

动态增强MRI以及循环DNA检测是预估regorafenib疗效的有效方法,可有效改善患者日常管理,提高治疗效益

Regorafenib是有效的转移性结直肠癌(mCRC)治疗方法,但缺少预测生物标志物、潜在毒性以及成本效用是Regorafenib治疗的潜在问题。近日,在一项II临床中,研究人员招募了RAS突变的转移性结直肠癌患者,在接受Regorafenib治疗前以及治疗15天后进行动态增强MRI检测,计算患者的KEF(治疗效果衡量指标),同时评估患者循环肿瘤DNA数量以及肿瘤血管评价分数。研究招募患者27人,其中平均KEF下降58.2%,研究发现,KEF下降超过70%与更高的疾病控制率(p=0.048)、无进展生存期改善(HR 0.16 (95% CI 0.04-0.72), p=0.02)、4个月无进展生存率提高(66.7% vs 23.5%)以及总生存率相关(HR 0.08 (95% CI 0.01-0.63), p=0.02)。KEF减少与组织活检CD31减少相关(p=0.04)。 治疗8周后,RAS突变DNA减少与无进展生存期(HR 0.21 (95% CI 0.06-0.71), p=0.01)以及总生存期(HR 0.28 (95% CI 0.07–1.04), p=0.06)相关。研

Sci Rep:恶性细胞可通过外泌体传递其恶性特征促进癌症的进展

本研究旨在了解来自高转移细胞系的外泌体是否会影响侵略性较差癌细胞的行为以及血管内皮细胞的特性。结果发现,转移性结肠癌细胞能够通过外泌体将其转移表型传递给同源原代癌细胞,此种形态转变与侵袭性行为更强相关。此外,来源于转移细胞系的外泌体(SW620Exos)导致内皮通透性增高的能力较来源于非转移性细胞系外泌体的能力强(SW480Exos)。基于SWATH定量蛋白质组学分析显示,细胞骨架相关蛋白中SW6

Sci Rep:血浆外泌体miR-125a-3p可作为早期结肠癌的诊断生物标志物

循环系统中外泌体在用于作为疾病的诊断和预后的生物标志物具有极大的潜力。本实验组既往研究中使用miRNA测序识别了异常表达的外泌体miRNA,将其作为结肠癌患者的候选诊断标志物。为验证此发现,本研究纳入了50名早期结肠癌患者和50名匹配的健康志愿者。分离其血浆来源的外泌体miRNA。实时定量PCR显示,早期结肠癌患者血浆外泌体的miR-125a-3p和miR-320c明显升高。ROC曲线显示,曲线下

Ann Oncol:基因检测助力癌症分型,结肠癌精准医疗实现生存率飞跃

来自德国,瑞士,美国和澳大利亚的科学家研究发现早期结肠癌患者可能会从预测性基因检测中受益更多,针对早期结肠癌患者的预测性基因检测能够帮助他们作出关于化疗的正确决策。

Oncol Res:大黄素通过诱导ROS依赖的自噬方式诱导结肠癌细胞凋亡。

近年来的研究表明,从中药中提取的大黄素对多种癌症,包括结肠癌有抗癌作用。然而,目前还没有很好的理解大黄素的这一抗癌机制。为了进一步认识大黄素的抗癌作用,研究者开展了一系列试验。

Lancet Oncol:TAS-102 联合贝伐单抗有效治疗难治性转移性结直肠癌

日本的Kuboki教授在The Lancet Oncology杂志上发表研究,评估了TAS-102 联合贝伐单抗治疗标准治疗难治性或不耐受的转移性结直肠癌,结果表明两药的联合具有抗肿瘤协同作用,且安全性可控。

Cochrane Db Syst Rev:氟尿嘧啶:口服用药和静脉给药,疗效有区别吗?

氟尿嘧啶类药物是结直肠癌(CRC)治疗的必要组成部分,患者通常更愿意选择口服片剂,因其安全、使用方便,但口服与静脉(IV)剂型的作用真的完全相同吗?这项研究发现CRC无论是治愈性治疗还是姑息性治疗时,IV和口服氟尿嘧啶的作用并不完全相同。
