Effect of Shenqi Fuzheng Injection on Leukopenia and T-cell Subsets in Patients with Non-small Cell Lung Cancer Undergoing Radiotherapy

Abstract

Purpose. The aim of this study is to evaluate the effect of Shenqi fuzheng injection on leukopenia and T-cell subsets in patients with non-small cell lung cancer (NSCLC) undergoing radiotherapy. Methods. A total of 124 patients with advanced NSCLC treated in the oncology department of our hospital from January 2017 to January 2019 were included and assigned at a ratio of 1 : 1 to receive conventional radiotherapy (control group, n = 62) or conventional radiotherapy plus Shenqi Fuzheng injection (study group, n = 62) via the random number table method. Results. The study group showed a significantly higher objective response rate (ORR) and a lower incidence of leukopenia versus the control group ( $P<0.05$ ). After the treatment, Shenqi Fuzheng injection resulted in significantly lower levels of carcinoembryonic antigen (CEA) and neuron-specific enolase (NSE) in the study group versus conventional treatment given to the control group. After the treatment, the control group showed significantly decreased ratios of CD3+ T cells, CD4+ T cells, and CD4+/CD8+, and an increased ratio of CD8+ T cells, and significant differences when compared with the study group. The T-cell subsets of the patients in the study group showed no significant changes than those between the treatment. The median OS was 20.0 months in the control group and 23.5 months in the study group. The differences between the two groups in terms of OS did not come up to the statistical standard. Conclusion. Shenqi Fuzheng injection for NSCLC patients undergoing radiotherapy elevates the number of white blood cells, regulates T-cell immune function, reduces tumor markers, and enhances clinical efficacy. Further clinical trials are, however, required prior to clinical promotion.
