 爱尔兰学者2月23日在线发表于《英国外科杂志》的一项荟萃分析表明,直肠癌新辅助放化疗(CRT)后病理完全缓解(pCR)与良好的长期生存状况有关,且局部复发和远处转移率低。   研究者搜索了3个主要的数据库(PubMed、MEDLINE和Cochrane图书馆),收集了1950年1月~2011年3月发表的所有英文论著,这些论著均报告了直肠癌新辅助CRT后pCR患者的长期生存转归。   结果显

 爱尔兰学者2月23日在线发表于《英国外科杂志》的一项荟萃分析表明,直肠癌新辅助放化疗(CRT)后病理完全缓解(pCR)与良好的长期生存状况有关,且局部复发和远处转移率低。

  研究者搜索了3个主要的数据库(PubMed、MEDLINE和Cochrane图书馆),收集了1950年1月~2011年3月发表的所有英文论著,这些论著均报告了直肠癌新辅助CRT后pCR患者的长期生存转归。

  结果显示,共有16项研究(3363例患者,1263例pCR,平均年龄60岁,65.0%为男性)纳入了最终分析。

  与未缓解者相比,pCR者局部复发率[比值比(OR)为0.25,P=0.0002]和远处转移率(OR为0.23,P<0.001)较低,5年生存率(OR为3.28,P=0.001)和无病生存率(OR为4.33,P<0.001)较高。

同步放化疗治疗直肠癌期间患者报告的急性胃肠道症状

背景:虽然目前已知基于5-氟尿嘧啶的直肠癌标准放化疗方案会导致明显的急性胃肠道(GI)毒性,但是关于患者报告的结局(PROs)的研究仍然十分有限。作者通过本研究评估了将PRO评价整合于常规临床实践的可行性,并描述了治疗期间症状发展的轨迹。 方法:77名在2006-2008年间接受治疗的连续患者被纳入研究。患者每周在医师处复诊后立即完成一份有7个项目的肠道问题量表。 结果:问卷完成率为95%。个

BMJ:预防结直肠癌,全谷物食品很有效

 MedSci点评:  实际上,这个观点不少学者都已认同,但是缺少循证医学的证据,这篇文章恰被这个空缺。当然,有关全谷食物对结直肠癌的影响,仍然有很多科学问题需要回答。例如,中国人群中以往直肠癌发生比例很低,近年来快速上升,是否与中国经济发展后,饮食结构发生变化有关?虽然,经验告诉我们可能相关,但是更需要大规模临床调查数据作支持,这正是高质量文章源泉之一。另外,目前所谓的

病案报道:转移性直肠癌合并巨大乙状结肠憩室

引言   巨大结肠憩室(GDC)是一种临床少见但意义重大的疾病,它常被认为是某一种已经存在的结肠憩室的并发症,其病因不明,常常表现为巨大单发憩室,好发于乙状结肠,且伴有各种症状和体征。有趣的是,此前并无此疾病并发直肠癌的文献报道。本文首次报道一例巨大乙状结肠憩室并发转移性直肠癌病例。  病例报告:    高加索(爱尔兰)女性,66岁,因下腹部疼痛,慢性便秘及腹部膨隆至我院

调整化疗方案不能改善直肠癌手术预后

 芝加哥(EGMN)——美国临床肿瘤学会(ASCO)年会上公布的NSABP R-04研究结果显示,用卡培他滨和奥沙利铂加强标准术前放化疗不能改善直肠腺癌患者的手术预后,而且加用奥沙利铂反而增加了毒性。在这项Ⅲ期临床研究中,奥兰多M. D.安德森癌症中心的外科主任Mark S. Roh博士在1,608例Ⅱ期和Ⅲ期直肠腺癌患者中对4种放化疗方案进行了比较。该研究于2004年启动,当时是一项比
