目前,在临床上针对转移性结肠癌的一线治疗方式:化疗联合北伐单抗疗法的最优治疗时间仍然是未知的。CAIRO3试验的研究目的在于评估卡培他滨联合贝伐单抗进行维持治疗与观察组相比疗效何如。该结果在线发表于2015年4月8日的The Lancet杂志上。

该研究是一项开放、随机对照的3期临床试验。研究人员从荷兰国内64个医院招募受试患者。纳入标准为年龄大于18岁,患转移性结肠癌,未曾接受过治疗,在6个3周为周期的卡培他滨/奥沙利铂/贝伐单抗(CAPOX-B)的诱导治疗后疾病状态稳定或较好,WHO评分0-1,骨髓、肝脏、肾脏功能正常。将所有受试患者按1:1比例随机分配至观察组或维持组,维持组给予卡培他滨和贝伐单抗治疗。通过中央最小化进行随机化分组,根据既往辅助性化疗、对诱导治疗的应答水平、WHO评分、血清乳酸脱氢酶含量、治疗中心等进行分层。所有受试者与研究者对分组情况均知晓。每9周评估一次疾病状态。疾病第一次进展时(PFS1),患者均接受CAPOX-B诱导治疗直至第二次进展(PFS2),主要评估指标为第二次疾病进展。所有终点事件均从随机化开始时进行计算。通过意向治疗进行分析。

结果显示,从2007年5月30日至2012年10月15日,共有558名患者参与了随机分组,维持组与观察组各279例。中位随访期为48个月(IQR36-57)。维持组的主要评估指标——中位PFS2较观察组有显著提升:观察组8.5个月,维持组11.7个月(HR 0•67, 95% CI 0•56–0•81, p<0•0001)。当PFS1发生后进行任何治疗,该差异仍保持显著。维持组的药物耐受性更好,尽管该组手-足综合征发病率有所增加(在维持治疗过程中64例[23 %]患者出现手-足皮肤反应)。在维持治疗中,整体生存质量未出现恶化现象,两组临床指标未有明显不同。

因此作者得出结论:在治疗转移性结肠癌患者时,在6个周期的CAPOX-B治疗后给予卡培他滨联合贝伐单抗进行维持治疗能够有效控制疾病并且不会影响生活质量。

Cell death &differ:CR1调控结肠癌肿瘤干细胞功能

近日,国际期刊cell death&differentiation 在线发表了意大利科学家的一项最新研究进展,他们发现胚胎期蛋白Cripto-1(CR1)在结肠癌肿瘤干细胞中表达能够促进肿瘤干细胞的克隆形成,这项研究表明CR1可能通过促进结肠癌肿瘤干细胞生长导致结肠癌复发。 最近,细胞干性被描述为一种动态变化,在正常细胞和肿瘤细胞中都可能存在。研究人员发现胚胎期蛋白Cripto-1(CR1)

来自新加坡南洋理工大学(NTU Singapore)和欧洲最大的医科大学——瑞典卡罗林斯卡医学院的研究人员发现,现有用于治疗白血病的化疗药物可以预防和控制结直肠肿瘤的生长。大肠癌是常见的恶性肿瘤,包括结肠癌和直肠癌。大肠癌的发病率从高到低依次为直肠、乙状结肠、盲肠、升结肠、降结肠及横结肠,近年有向近端(右半结肠)发展的趋势。其发病与生活方式、遗传、大肠腺瘤等关系密切。发病年龄趋老年化,男女之比为1

Clin Col Cancer:避免不必要药物副作用?血检也能做到!

一项由曼彻斯特研究人员发表的最新研究显示,血液测试能够在早期对肠癌患者是否获益于更为密集的化疗进行识别,进而为避免不必要的化疗而带来的药物副作用提供可能。该项研究结果发表在最新一期Clinical Colorectal Cancer杂志上。结直肠或肠道癌症是欧洲第二大癌症杀手。对于这一类肿瘤的治疗,最常见的方式是多种化疗药物联合应用,有助于提高药物治疗的效果。然而,这种多药联用的方法将可能增加药物
