Lancet Oncol:完整结肠系膜切除术(CME)改善了结肠癌患者的预后

2015-01-12 MedSci MedSci原创

背景:对结肠癌患者进行完整结肠系膜切除术(CME)改善了结肠癌患者的预后。我们探究一下,相比于传统结肠切除,完整结肠系膜切除术是否延长了结肠癌患者的DFS。 方法:2008年1月1日至2011年12月31日在丹麦首都地区进性结肠切除术的I-III期结肠癌患者纳入了这个大型研究。其中CME组中的患者是在经认证能实行CME手术的医院进行了CME手术的,对照组的中患者是在另外三家医院进行了传统结肠切除

背景:结肠癌患者进行完整结肠系膜切除术(CME)改善了结肠癌患者的预后。我们探究一下,相比于传统结肠切除,完整结肠系膜切除术是否延长了结肠癌患者的DFS。

方法:2008年1月1日至2011年12月31日在丹麦首都地区进性结肠切除术的I-III期结肠癌患者纳入了这个大型研究。其中CME组中的患者是在经认证能实行CME手术的医院进行了CME手术的,对照组的中患者是在另外三家医院进行了传统结肠切除术的。资料的收集来自于丹麦结直肠癌数据库(DCCG)和医用图表。如果患者是IV期病人,异时结直肠癌,直肠癌(距离肛周小于等于15cm),阑尾肿瘤或R2切除则排除。生存资料在2014年11月12日从DCCG数据库中采集。

发现:CME组中有364名患者,对照组中有1031名患者。对于所有患者,CME组4年DFS是85.8%(95%CI 81.4-90.1),对照组是75.9%(72.2-79.7)。I期患者,CME组4年DFS是100%,对照组是89.8%(83.1-96.6)。II期患者,CME组4年DFS是91.9%(95%CI 87.2-96.6),对照组是77.9%(71.6-84.1)。III期患者,CME组4年DFS是73.5%(95%CI 63.6-83.5),对照组是67.5%(61.8-73.2)。多变量COX回归曲线表明CME手术是一个能显著提高所有患者(HR 0.59,95%CI 0.42-0.83)以及II期患者(0.44,0.23-0.86)、III期患者(0.64,0.42-1.00)DFS的独立预后因素。倾向评分匹配之后,无论UICC分期,CME术后患者的DFS都明显延长:CME组4年DFS为85.8%(95%CI 81.4-90.1),对照组是73.4%(66.2-80.6)。

结论:我们的数据表明,针对I-III期结肠腺癌患者,相对于传统结肠癌手术,CME手术能带来更好的DFS。施行CME手术极有可能会改善结肠癌患者的预后。

JNCI:DPYD变异能够作为5-FU在结肠癌辅助化疗中毒性的预测因子(NCCTG N0147)

研究背景:5-FU在体内的分解经过3个酶促催化步骤完成,其中二氢嘧啶脱氢酶(dihydropyrimide dehydrogenase,DPYD/DPD)是嘧啶类分解代谢的起始和限速酶,将5-FU还原为二氢氟尿嘧啶(FUH2),再经过另外2种酶催化形成最终代谢产物经肾脏排出体外。DPYD作为5-FU分解过程的关键酶,其活性高低直接决定了5-FU进入合成代谢和产生核苷酸类似物的量。药代动力学研究显示

PNAS:激素作祟?睾丸酮或成结肠癌重要推手

过去的研究指出,对于结肠癌、胰腺癌以及胃癌等无性别特异性的肿瘤,男性似乎比女性患病率更高。科学家们推测引起这种现象的原因,在于女性可能受到雌性激素如雌激素的保护,阻止了肿瘤的形成。而今,来自密苏里州大学的研究人员发现,有证据支持男性激素睾丸酮可能是结肠肿瘤形成的相关因素。该研究成果发表在最新一期的Proceedings of the National Academy of Sciences杂志上。
