Efficacy of Standardised Treatments Combined with Ubenimex in Patients with Malignant Tumors

Ubenimex is widely used as an immunomodulator in the treatment of leukemia and non-small cell lung cancer to improve the anti-tumor treatment effect. However, there has not been any multicenter randomised controlled trials to study its impact on the prognosis of cancer patients. The authors aimed to conduct a meta-analysis to initially study these issues. Pubmed, Cochrane Library and EMbase were searched. Randomised controlled trials of the effects of ubenimex on the survival rate of malignant tumor patients were included in the meta-analysis. Survival rate ratio (OR) and 95% confidence interval (95% CI) between two groups were used to evaluate the efficacy of ubenimex. Fixed effects models were used for meta-analysis. A total of 1,372 cases (684 in the ubenimex group and 688 in the control group) of five studies were included. Between the ubenimex group and the control group, the 1-year OR was 1.40 (95% CI = 1.06 to 1.85), the 2-year OR was 1.43 (95% CI = 1.08 to 1.89) and the 3-year OR was 1.39 (95% CI = 1.07 to 1.81). Standardised treatments combined with ubenimex may improve the survival rate of patients with malignant tumors.
