ABSTRACT
<p><b>BACKGROUND</b>To compare the therapeutic effect, adverse reaction and effect on immunity of chemotherapy combined Aidi injection (AI) with those of chemotherapy alone in the treatment of advanced non small cell lung cancer (NSCLC).</p><p><b>METHODS</b>Ninety eight cases of advanced NSCLC were randomly divided into two groups, trial group and control group. In the trial group, NP plus AI (60 80 ml) were given intravenously by dissolving in 400 ml of normal saline per day for 8-10 days, while in the control group, only NP chemotherapy was given. Navelbine (25 mg/m², d1, 8) and cisplastin (40 mg/m², d1-3) were chosen in the chemotherapy. Each patient received at least two cycles of treatment.</p><p><b>RESULTS</b>The effective rate in the trial group and the control group was 53.1% and 44.9% respectively, without significant difference between the two groups ( P > 0.05). But the rate of progression, adverse reactions in bone marrow and digestive tract, and change of immunity in the trial group were all lower than those in the control group ( P < 0.05), and the improvement in Karnofsky score in the trial group was higher than that in the control group ( P < 0.05).</p><p><b>CONCLUSIONS</b>Chemotherapy of NP combined with AI shows benefit in the treatment of advanced NSCLC. AI could decrease the influence on immunity and adverse reaction of chemotherapy, and improve the quality of life in patients with NSCLC.</p>
