| 摘 要： | Objective:To verify the efficacy and safety of Quxie Capsule(祛邪胶囊) in patients with metastatic colorectal cancer(mC RC).Methods:The present study was a randomized,double-blind,placebo-controlled trial.Sixty patients with mC RC were randomized into two groups at a 1:1 ratio by sealed envelope.The treatment group received conventional therapy combined with Quxie Capsule for 3 months.The control group was treated with conventional therapy combined with placebo for 3 months.Main outcome measures were overall survival(OS) and progression-free survival(PFS).Subgroup analysis was performed according to age,right or left-sided disease,and second-line therapy to determine the differences in PFS and OS between the two groups.Patients were followed up every 3 months until Dec 31 st 2016.Results:The median OS was 23 months in the treatment group [95% confidence interval(CI):15–not calculated] vs.14 months in the control group(95% CI:11–22,P=0.060).The OS of the treatment group tended to be longer than that of the control group(P0.05).In the subgroups of patients 65 years old,left-sided colon,and 2 nd-line therapy,the treatment group showed a significant survival benefit compared with the control group(P=0.006,0.038,0.013,respectively).There were no significant differences between the two groups in PFS(P0.05).Safety analysis showed no severe hematological toxicity or liver and renal function injury in the treatment group.Conclusions:Quxie Capsule showed good safety and efficacy,and could prolong the OS of patients with mC RC.
