BACKGROUND/AIM: Presently, there are no therapeutic options for unresectable hepatocellular carcinoma (u-HCC) patients who are intolerant to sorafenib or regorafenib failure. There have been no reports with detailed clinical findings of lenvatinib (LEN), a newly developed first-line tyrosine kinase inhibitor (TKI), obtained in real-world practice. We aimed to elucidate the therapeutic efficacy of LEN.
MATERIALS/METHODS: From March to August 2018, 105 u-HCC patients were treated with LEN. Following exclusion of those who started with a reduced LEN dose and/or had a short observation period (<2 weeks), 77 patients (72.0 ± 8.9 years, 59 males, 8 mg/12 mg = 49/28, Liver Cancer Study Group of Japan 6th [LCSGJ]-TNM stage II/III/IVa/IVb = 8/28/4/37, and American Joint Committee on Cancer/Union for International Cancer Control 8th [AJCC/UICC]-TNM stage IB:II:IIIA:IIIB:IVA:IVB = 2:27:6:5:9:28) were divided into two groups (TKI naïve [n = 33] and TKI experienced [n = 44], including 11 with regorafenib history). Therapeutic response was evaluated using mRECIST. Clinical data were retrospectively evaluated.
RESULTS: There were significant differences in age (74.6 ± 11.2 vs 70.0 ± 5.9 years, P = 0.040), LCSGJ-TNM (II:III:IVa:IVb = 8:12:1:12 vs 0:16:3:25, P = 0.006), and AJCC/UICC-TNM (IB:II:IIIA:IIIB:IVA:IVB = 2:17:1:1:4:8 vs 0:10:5:4:5:20, P = 0.028), while hepatic reserve function, adverse event (AE) profiles, and progression-free survival (89.7%/80.4% vs 90.5%/80.1%, P = 0.499) and overall survival (96.7%/96.7% vs 100%/92.3%, P = 0.769) after 4 and 12 weeks were not significantly different between the TKI-naïve and TKI-experienced groups. Overall response rate and disease control rate at 4 weeks (n = 52) were 38.5% and 80.8%, respectively, and 32.4% and 70.3%, respectively, at 12 weeks (n = 37). A significant decline in log10 AFP from the baseline to 4 weeks after introducing LEN was observed in patients with PR and SD (2.047 ± 1.148 vs 1.796 ± 1.179, P < 0.001).
CONCLUSION: Regardless of past TKI therapy, therapeutic response and AEs after introducing LEN were similar. LEN may be an important treatment for the present unmet need regarding TKI treatment against u-HCC.
