Clinical Effect of the Combination of Compound Kushen Injection and Gemcitabine on Postoperative Patients with Non-Muscle Invasive Bladder Cancer and Its Influence on Serum-Related Factors

Objective: To observe the clinical effect of the combination of compound Kushen injection (CKI) and gemcitabine on postoperative patients with non-muscular invasive bladder cancer (NMIBC) and its influence on serum-related factors. Methods: A total of 150 patients with NMIBC were randomly divided into two groups. The patients in the control group (n = 75) received gemcitabine therapy; They were given 0.2 g gemcitabine once a week for 8 weeks after surgery and then changed to once every 2 weeks for eight times. The patients in the observation group (n = 75) were given CKI treatment on the basis of the control group for 10 days. The treatment was continued for three courses. After continuous follow-up for 2 years, the blood biochemistry, serum-related factors and immune T cell subsets and the safety and immune function changes, total effective rate, recurrence rate and occurrence of adverse reactions were evaluated. Results: The interferon-γ, interleukin (IL)-2, clusters of differentiation (CD)8+, serum cell adhesion molecules (CAMs), hepatocyte CAM and cysteine proteinase-8 levels in the two groups after treatment significantly increased compared with those before treatment (p < 0.05), with the observation group showing more increase (p < 0.05). However, the tumour necrosis factor-α, C-reactive protein (CRP), IL-6, CD3+, CD4+, matrix metalloproteinase (MMP)-9, MMP-2, epithelial-specific CAM, soluble CAM-1, liver CAM, E-cadherin, vascular endothelial growth factor and fibroblast growth factor levels decreased significantly after treatment (p < 0.05), with the observation group exhibiting more decrease (p < 0.05). The adverse reactions and recurrence rate in the observation group obviously decreased in comparison to those in the control group (p < 0.05). Conclusions: The combination of CKI and gemcitabine can improve the inflammatory response, relieve the clinical symptoms of patients and reduce adverse clinical symptoms during gemcitabine infusion chemotherapy, with high safety.
