PURPOSE: To investigate the protective effects of berberine on radiation-induced lung injury (RILI) in non-small cell lung cancer (NSCLC) patients treated withradiotherapy. PATIENTS AND METHODS: In this randomised, double-blind study, 90 patients with NSCLC were divided into two groups. The trial group received radiation therapy plus berberine, and the control group received radiation therapy plus a placebo for 6 weeks. Soluble intercellular adhesion molecular-1 (sICAM-1) and transforming growth factor-beta-1 (TGF-beta1) were measured. RILI and pulmonary function were evaluated at 6 weeks and 6 months after treatment, respectively. RESULTS: Of the 90 patients enroled, 43 in the control group and 42 in the trial group completed the study. The incidence of RILI was significantly lower in the trial group at 6 weeks and 6 months than that in the control group (45.2% versus 72.1% and 35.7% versus 65.1%, respectively, both P<0.05). sICAM-1 levels in the trial group were significantly lower at weeks 6 and 12 (373.64+/-89.33 versus 459.53+/-123.59 and 447.83+/-111.21 versus 513.91+/-150.46, both P<0.01), and plasma TGF-beta1 levels were lower at week 3 and 6 (5.43+/-1.47 versus 6.22+/-1.78 and 5.93+/-2.39 versus 7.67+/-2.74, P<0.05 and 0.01, respectively) in comparison with the control group. Significant differences were observed in FEV1 (P=0.033) and DLCO (P=0.003) between patients receiving berberine and those receiving placebo. Independent-samples T-test showed reductions from baseline FVC at week 6 (P<0.05), and FEV1 and DLCO at month 6 (P<0.05 and 0.01, respectively) in the trial group were significantly smaller than that in the control group. CONCLUSION:Berberine significantly reduced the incidence of RILI, improved PF and decreased the levels of sICAM-1 and TGF-beta1. The exact mechanisms remain to be further explored.
