Effect of Feitai Capsule(肺泰胶囊) on Quality of Life and Progression-Free Survival of Patients with Unresectable Non-Small Cell Lung Cancer

<正>Objective:To examine the effect of a Chinese medicinal herbal formula(Feitai Capsule,肺泰胶囊) on the quality of life(QOL) and progression-free survival(PFS) of patients with unresectable non-small cell lung cancer(NSCLC).Methods:Sixty-two patients were randomly divided into the treatment group(31 cases) and the control group(31 cases).For the treatment group,4 capsules(1.2 g/capsule) of Feitai Capsule were administered 3 times a day after meals for 3 weeks;then no drug was administered for 1 week.This schedule was continued for at least 3 more cycles(12 weeks totally).If there were no obvious toxic reactions,the treatment was extended.The patients were evaluated at least once every 8 weeks until progressive disease(PD). For the control group,the regular follow-up and evaluation were performed at least once every 8 weeks until PD.Clinical symptoms,objective response,physical constitution and energy,QOL,and PFS were evaluated regularly.Analysis of variance(ANOVA),a non-parametric test,and analysis of covariance were used to compare clinical features,amelioration of clinical symptoms,physical constitution and energy,and QOL.Kaplan-Meier analysis was used to compare the two-group PFS.Results:Sixty patients finished the final evaluation, with 30 patients in each group.Baseline characters between groups were not significantly different(P0.05). The control group had a 36.7%improvement in clinical symptoms,while the treatment group had a 73.3% improvement.This difference was statistically significant(Z=-2.632,P=0.008).The control group had a 26.7% improvement in the Karnofsky performance status(KPS),while the treatment group had a 53.4%improvement. This was also significantly different(Z=-2.182,P=0.029).A comparative analysis indicated a positive correlation (r=0.917,P0.001).Compared with the control group,QOL in the treatment group was significantly improved, except in the social/family condition and doctor-patient relationship indicators.The PFS of the treatment group and control group were 6.23 months and 4.67 months,respectively(P=0.048).Conclusion:Feitai Capsule,a Chinese medicinal herbal treatment could improve the QOL and extend the PFS of the unresectable NSCLC patients.
