OBJECTIVE:To observe clinical efficacy and safety of Astragalus injection combined with neoadjuvant chemother-apy and three dimensional conformal radiotherapy in the treatment of colorectal cancer. METHODS:A total of 80 patients with me-dium and advanced colorectal cancer were selected from oncology department of our hospital during Jun. 2010 to Jun. 2014,and di-vided into observation group and control group according to random number table,with 40 cases in each group. Control group re-ceived neoadjuvant chemotherapy combined with three-dimensional conformal radiotherapy. Observation group was additionally giv-en Astragalus injection 10-20 mL added into 5% Glucose injection 250-500 mL,ivgtt,qd,on the basis of control group. A treat-ment course lasted for 21 d,and both groups received 3 courses. Short-term efficacies as well as immune indexes [CD3+,CD4+, CD4+/CD8+ and NK cells] before and after treatment were observed in 2 groups. The occurrence of ADR and survival situation were compared between 2 groups. RESULTS:Clinical response rate of observation group was 87.5%,which was slightly higher than that of control group(77.5%),but there was no statistical significance(P>0.05). Before treatment,there was no statistical signifi-cance in immune index levels between 2 groups(P>0.05). After treatment,NK cells,CD3+,CD4+ and CD4+/CD8+ levels of con-trol group were decreased significantly,which was significantly lower than observation group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). Two-year survival rate of observa-tion group was significantly higher than that of control group;the recurrence rate and distant metastasis rate were significantly low-er than control group,with statistical significance(P<0.05). CONCLUSIONS:Astragalus injection not only can improve therapeu-tic efficacy of neoadjuvant chemotherapy in patients with colorectal cancer,balance inflammatory state,improve survival rate,re-duce recurrence rate and distant metastasis rate with good safety.
