Differences Between Sorafenib and Lenvatinib Treatment from Genetic and Clinical Perspectives for Patients with Hepatocellular Carcinoma

BACKGROUND: The aim of this work was to systematically compare the differences between sorafenib and lenvatinib for patients with hepatocellular carcinoma (HCC) from genetic and clinical perspectives. MATERIAL/METHODS: The mRNA and miRNA sequencing information of patients with HCC treated with either sorafenib or lenvatinib was analyzed using differential expression and a protein–protein interaction assay. The clinical manifestations and adverse events of the 2 drugs were also investigated. RESULTS: Compared with patients with HCC treated with sorafenib, patients treated with lenvatinib developed 8 differentially expressed genes (DEGs, FGF4, FGF23, UNC13C, RIMBP2, STXBP5L, PHOX2B, NEUROD4, and POU4F2) and 3 miRNAs (DEMs, has-miR-548ah, has-miR-888, and has-miR-196a-1), of which hsa-miR-548 regulated 4 target genes, the largest number among the 3 miRNAs. The functions of these DEMs and DEGs were verified by external experiments in the HCC cell line Hep3B2.1–7. We further investigated the adverse events of the drugs for patients with advanced HCC in clinical treatment. The patients in the sorafenib group developed less frequent symptoms of hypertension and diarrhea. Also, the frequency of hand-foot skin reactions in patients treated with lenvatinib was lower than that of patients treated with sorafenib (P<0.05). There were no significant differences in nausea, fatigue, frequent urination, and dizziness (P>0.05). CONCLUSIONS: In a time of increasing interest in chemotherapy drug treatments for patients with HCC, this study provided a better understanding of the clinical evaluations of sorafenib and lenvatinib.
