Systematic Review of the Efficacy and Safety of Lenvatinib in Various Solid Tumors

Objective The purpose of this study was to investigate the efficacy and safety of lenvatinib in various types of solid tumors. Method By searching PubMed, Web of Science, Cochrane, CNKI, Wanfang and other databases, all the literatures about the comparison of clinical efficacy of lenvatinib in the treatment of various solid tumors. According to the criteria of inclusion and exclusion of literature, two participants screened the literature, collated the data and evaluated the literature. RevMan 5.4 software was used for meta-analysis of the included literatures. Results A total of 12 studies were included, including 5213 patients. Meta-analysis showed that, in terms of efficacy, the risk (HR) of prolonging PFS in the treatment of various solid tumors in the lenvatinib group was 1.91 times that in the control group (HR = 1.91, 95% CI: 1.58-2.31, P < 0.00001), and the risk (HR) of prolonging OS was 1.27 times that in the single targeted drug group (HR = 1.27, 95% CI: 1.15-1.40, P < 0.00001). In terms of safety, the risk of adverse events in the treatment of various solid tumors in the lenvatinib group was higher than that in the control group, especially in Endocrine Toxicities, Renal/Urinary Toxicities, Vascular Toxicities, Musculoskeletal/a Connective Tissue Toxicities and Metabolism/Nutrition Toxicities. Conclusions Lenvatinib in various solid tumors can prolong OS and disease PFS of patients, improve the clinical benefit rate and improve the quality of life of patients. At the same time, there is a certain incidence of adverse events, and symptomatic intervention should be given in clinical medication.
