目的：通过临床数据挖掘观察晚期大肠癌患者用药的聚集现象,客观地探索组方用药规律。方法：首先利用EXCEL统计数据库各味药的用药频次,对高频中药进行性味归经与药效频次的统计,然后将晚期大肠癌患者长期服用的基础方分别纳入扶正组与祛邪组,最后运用SPSS21导入数据,运用系统聚类法对高频中药进行聚类分析。结果：选取用药频次在前30的高频中药,按药性统计频次,由高到低依次为温性,寒性,平性,凉性;按药味统计频次,依次为甘味,苦味,淡味,辛味,酸味,涩味;按药物归经统计频次,依次为脾经、胃经、肺经、肝经、肾经等;按药效统计频次,依次为补虚药、理气药、消食药、利湿化痰药等;扶正组与祛邪组各形成三个聚类方,配伍以健脾益气,燥湿化痰为主。结论：治疗晚期大肠癌多以温性、归脾胃经、补虚药为主,以扶正抗癌为治疗原则。
