JCO:结直肠癌幸存者的高死亡风险和吸烟有关

吸烟的结直肠癌幸存者的死亡风险比不吸烟幸存者要高两倍以上,加上现有的证据表明,吸烟和结直肠癌的发生率和死亡率息息相关。结果来源于美国癌症协会的研究人员的一项新的研究,其中最大的一项研究是吸烟和结直肠癌幸存的关系,第一项研究便是前瞻性的收集诊断前和诊断后的吸烟信息。这项研究早期在线发表在临床肿瘤学杂志。   

现有证据表明吸烟者被诊断为结直肠癌的几率要高很多,但其与被诊断为结直肠癌后存活的关联尚不清楚。为了研究吸烟、诊断前后和结直肠癌的引起、死亡率之间的关系,彼得•坎贝尔博士领导的研究小组从美国癌症协会的癌症预防研究II的184,000个成年人中确认了2,548名新确诊的患有侵袭性、非转移性的结直肠癌患者。在2,548名结直肠癌幸存者中,有1,074名患者在随访后平均7.5年去世,还包括453名死于结直肠癌。

研究人员发现,那些吸烟者在诊断前有各种原因死亡的风险超过两倍(相对风险[RR] = 2.12)以及从死于大肠癌的风险(RR,2.14)。诊断前吸烟与较高的全因死亡率相关(RR,1.18),但与结直肠癌导致的死亡率无关。在整个研究过程中,确诊后吸烟与总死亡率(RR,2.22)相关,同时也与结直肠癌的死亡率(RR,1.92)近两倍的风险相关。

研究者称这种现象也是合理的,吸烟者在病理学上有更强的肿瘤侵袭性,或者说,吸烟可能会降低结直肠癌的治疗效果。“进一步的研究需要了解的机制是吸烟可能会增加结直肠癌的死亡率并确定是否通过确诊后戒烟来降低结直肠癌的死亡率”,研究者说。

JAMA Surg:IV期结直肠癌,切除率vs生存率时间变化趋势

近日,美国德克萨斯大学MD安德森癌症中心肿瘤外科的医师们进行了一项回顾性队列研究,发现随着时间的推移,IV期结直肠癌患者原发肿瘤手术切除率不断下降,但患者生存率得到提高,最新研究成果在线发表于1月14日的JAMA Surg杂志上。

Ⅳ期结直肠癌原发肿瘤切除术或过度使用

美国M.D.安德森癌症研究中心的一项回顾性队列研究表明,尽管大多数Ⅳ期结直肠癌">结直肠癌患者均接受原发肿瘤切除术,但从2001年开始,原发肿瘤切除手术呈现逐渐递减趋势。虽然原发肿瘤切除比率下降了,但患者存活却较以往有所改善,提示原发肿瘤切除术对于患Ⅳ期结直肠癌患者的治疗可能不是常规必要的。论文1月14日在线发表于《美国医学会 外科学》(JAMA Surg)杂志。 该研究旨在评估原发肿瘤切

ASCO GI 2015 :高维生素D水平可改善进展期结直肠癌患者生存

一项关于新诊断转移性结直肠癌">结直肠癌患者的Ⅲ期研究的前瞻性数据分析显示,化疗和靶向治疗后维生素D水平较高的患者其结局更好,维生素D水平最高和最低的患者中位总生存期分别为32.6个月和24.5个月。 主要研究作者、达纳-法伯癌症中心、哈佛医学院Kimmie Ng助理教授:我们的研究显示高维生素D水平与显著改善生存有关,最终目标是希望通过这一结果指导补充维生素D治疗结直肠癌的随机研究,从而

JAMA Surg:原发肿瘤切除术或不能提高Ⅳ期结直肠癌生存率

一项美国回顾性研究显示,1988年~2010年间,大多数Ⅳ期结直肠癌(CRC)患者曾接受过原发肿瘤切除手术,而自2001年起,原发肿瘤切除手术的临床使用逐渐减少,但患者生存率较前改善。随着化疗药物及生物制剂的不断问世,CRC原发肿瘤切除手术或已不再是常规治疗方式。论文1月14日在线发表于《美国医学会杂志·外科学》(JAMA Surg)。 研究纳入美国国立癌症研究所CRC监测、流

JCO:吸烟让结直肠癌幸存患者更接近死神

近日,刊登在国际杂志Journal of Clinical Oncology上的一篇研究论文中,来自国外的研究人员通过研究表明,相比不吸烟的结直肠癌幸存者而言,吸烟的患者死亡的风险是前者的2倍,这就揭示了吸烟和结直肠癌患者死亡直接相关,该研究为后期开发有效的干预措施来预防结直肠癌患者的死亡风险提供了一定的帮助。 文章中研究者对美国癌症协会癌症预防研究II期阶段中从18.4万成年人中诊断出

JCO:结直肠癌患者FOLFIRI+爱必妥的应用以及RAS突变状态的研究

目的:CRYSTAL是一项III期临床试验,它表明了在KRAS外显子2(密码子12、13)野生型的转移性结直肠癌(mCRC)患者的一线治疗中,FOLFIRI(氟脲嘧啶+亚叶酸钙+伊立替康)方案加上西妥昔单抗能显著提高患者的OS、PFS和客观缓解率。通过更多的RAS基因检测对本试验进行亚组再分析。 材料和方法:将CRYSTAL研究中KRAS外显子2野生型患者的组织样本重新进行其它RAS基因检测。包
