RESUMO
OBJECTIVE: To explore the enhancing effect of compound Kusheg injection in chemotherapy for patients with stage III and IV non-small cell lung cancer (NSCLC). METHODS: A total of 286 patients with advanced NSCLC were enrolled in this study. The patients were treated with either compound Kusheng injection in combination with NP (NVB + CBP) chemotherapy (vinorelbine and carboplatin, n = 144), or with NP (NVB + CBP) chemotherapy alone (n = 142). The chemotherapy was performed for 4 cycles of 3 weeks, and the therapeutic efficacy was evaluated every 2 weeks. The following indicators were observed: levels of Hb, WBC, PLT and T cell subpopulations in blood, serum IgG level, short-term efficacy, adverse effects and quality of life. RESULTS: The gastrointestinal reactions and the myelosuppression in the combination chemotherapy group were alleviated as compared with the chemotherapy alone group, showing a significant difference (P < 0.05). CD(8)(+) cells were markedly declined in the combination chemotherapy group, and the CD(4)(+)/CD(8)(+) ratio showed an elevation trend in the chemotherapy alone group. The KPS scores and serum IgM and IgG levels were higher in the combination chemotherapy group than those in the chemotherapy alone group (P < 0.01 and P < 0.05). The serum lgA levels were not significantly different in the two groups. CONCLUSION: The compound Kusheng injection plus NP chemotherapy regimen shows better therapeutic effect, reduces adverse effects of chemotherapy and improves the quality of life in patients with stage III and IV NSCLC.
