2016年7月20日讯/生物谷BIOON/--研究人员和医生们一直试图找到术后辅助化疗对早期结肠癌的作用,最近来自芝加哥伊利诺伊大学的研究人员发现了2期结肠癌病人接受辅助化疗与生存时间提高之间的关系,并且不管病人的年龄和患病风险如何,以及使用何种化疗药物,这种相关性都存在。相关研究发表在国际学术期刊Cancer上。据美国癌症学会估计今年美国将有超过95000人诊断为结肠癌,成为美国第三大常见癌症,并且是癌症相关死亡的第二大死因。许多研究表明辅助化疗能够帮助病人对抗晚期结肠癌。但是对2期结肠癌病人的作用效果一直未知,目前的临床指南只推荐医生将其作为高风险或可能出现术后复发的2期病人的治疗选择。文章作者Dr. Ajay Maker表示:“这项研究结果非常令人兴奋,并且有些结果是我们完全没有预料到的。许多年来的研究都包含2期结肠癌病人,但都不是研究的重点。该研究则以2期病人为重点研究对象,深入了解辅助化疗对2期结肠癌病人的治疗效果。”研究人员分析了国际癌症数据库中153110名2期结肠癌病人的健康信息,他们发现接受辅助化疗的病人比未接受辅助化疗的病人生存时间更长。但是作者也表示任何对治疗效果进行的回顾性研究都存在局限,“我们在进行回顾性研究寻找相关性的时候必须非常小心,但是这项研究确实证实还需要前瞻性研究发现能够从辅助化疗中获益最大的特定2期结肠癌病人亚群。”(生物谷Bioon.com)本文系生物谷原创编译整理,欢迎转载!点击获取授权。更多资讯请下载生物谷APP.原始出处:Adjuvant chemotherapy in early-stage colon cancer may improve survival DOI: 10.1002/cncr.30181Adjuvant chemotherapy is associated with improved survival in patients with stage II colon cancerLeigh Casadaban MD1, Garth Rauscher PhD2, Mebea Aklilu MD3, Dana Villenes MS4, Sally Freels PhD5 andAjay V. Maker MD1,*RESULTSAmong 153,110 patients with stage II colon cancer, predictors of receiving chemotherapy included age 65 years, male sex, nonwhite race, use of a community treatment facility, non-Medicare insurance, and diagnosis before 2004. Improved and clinically relevant OS was associated with the receipt of adjuvant chemotherapy in all patient subgroups regardless of high-risk tumor pathologic features (poor or undifferentiated histology, 12 lymph nodes evaluated, positive resection margins, or T4 histology), age, or chemotherapy regimen, even after adjustment for covariates and propensity score weighting (hazard ratio, 0.76; P.001). There was no difference in survival noted between single and multiagent adjuvant chemotherapy regimens. CONCLUSIONSIn what to the authors' knowledge is the largest group of patients with stage II colon cancer evaluated to date, improved OS was found to be associated with adjuvant chemotherapy regardless of treatment regimen, patient age, or high-risk pathologic risk features.
