Lancet Gas Hepa:中国专家率先发现,黄连素有助预防结直肠癌切除后复发

2020-01-09 袁蕙芸 陈静 中国新闻网

记者9日获悉,上海交通大学医学院附属仁济医院消化科房静远团队牵头研究结果证实:中国传统的中药黄连的提取物小檗碱(BBR,黄连素),具有一定的预防结直肠癌前疾病腺瘤肠镜下切除后复发的作用。

记者9日获悉,上海交通大学医学院附属仁济医院消化科房静远团队牵头研究结果证实:中国传统的中药黄连的提取物小檗碱(BBR,黄连素),具有一定的预防直肠癌前疾病腺瘤肠镜下切除后复发的作用。

该研究为腺瘤切除术后的化学预防提供了新的选择。

据悉,直肠癌是全球最常见的恶性肿瘤之一,其发病率有增长趋势。约90%以上的结直肠癌来源于结直肠腺瘤。在超过50岁人群中,腺瘤患病率约30到40%,肠镜下切除之可预防结直肠癌。房静远表示,但切除后1年腺瘤复发(再发)率30%以上、3年复发率50%左右。

据了解,国际上,相关学者和医生们一直在研究和开发化学预防其复发的药物和方法,所发现的药物多因为副作用或价格昂贵而难以普及应用。因此,结直肠癌预防成为公共卫生领域非常重要难题。

本次大规模的随机、双盲、安慰剂对照临床试验研究,由上海交通大学医学院附属仁济医院牵头,解放军总医院第七医学中心、天津医科大学总医院、南方医科大学南方医院、厦门大学附属中山医院、南京大学医学院附属鼓楼医院、同济大学附属上海第十人民医院七家医院消化科协同完成。

据悉,国际知名期刊《柳叶刀·肠病和肝病学》在线发表了房静远团队牵头的多中心随机双盲安慰剂对照研究结果。

另据了解,近十来年,针对结直肠癌发病和患病率的快速增长情况,房静远教授领衔团队在国际上率先研究证明了叶酸可预防50岁以上人群结直肠腺瘤的初次发生。仁济消化学科肠肿瘤研究团队还率先发现检测粪便中共生梭菌,可提前预警结直肠腺瘤和早癌。
