Objective: To observe the Aidi injection combined with chemotherapy for the treatment of advanced non-small cell lung cancer(NSCLC) clinically. Method: Based on inclusion criteria, 98 cases of NSCLC were randomly divided into observation group and the control group (n=49 each). Two groups were given TP chemotherapy:TAX (docetaxel) 65 mg/m², gtt 30-60 min, d₀; DDP(cisplatin) 25-30 mg/m², gtt, d₁-d₃.While the observation group was treated with Aidi injection 80~100 mL, adding 0.9% saline 400 mL gtt, a total of 14 d. Three weeks for both groups were lasted as a treatment cycle, 2 treatment cycles were used to evaluate the clinical efficacy and survival in patients with and without the occurrence of side effects. Result: The total effective rate was 91.84%, 77.55% in the two groups with significant difference (P<0.05). The quality of life in the observation group was higher compared with that in the control group significantly(P<0.05).CD3⁺,CD4⁺,CD4⁺ /CD8⁺, NK cells observed before and after treatment the difference was significant(P<0.05); CD4⁺,CD4⁺/CD8⁺, NK cells after treatment between the two groups was statistically significant(P<0.05).Two groups in bone marrow toxicity, peripheral neurotoxicity, vomiting and other side effects were statistically different(P<0.05). Conclusion: Aidi injection combined with chemotherapy in the treatment of clinical NSCLC shows significant effect. It can improve the quality of life, enhance immunity, reduce the chemotherapy-induced toxicity.
