Abstract Background/aim We assessed suitable factors indicating newly developed lenvatinib (LEN) treatment for unresectable hepatocellular carcinoma (u‐HCC) by investigating real‐world clinical features of patients. Materials/methods One hundred fifty two u‐HCC patients, who receive LEN treatment from March to December 2018, were enrolled. (Child‐Pugh score CPS 5/6/7/8 = 76/61/13/2, modified albumin‐bilirubin grade mALBI 1/2a/2b/3 = 53/35/60/4). Clinical features were evaluated retrospectively. Results Overall‐response rate (ORR)/disease control rate (DCR) at 1 month after starting LEN were 38.7%/86.0%, respectively. Estimated median time to progression (TTP) was 7.0 months, while median survival time was not reached within the observation period. CPS (≥7) and past history of tyrosine‐kinase inhibitor (TKI) were not significant prognostic factors. mALBI ≥2b was an only significant prognostic factor (HR 4.632, 95%CI 1.649‐13.02, P = 0.004) in Cox‐hazard multivariate analysis. In patients with Child‐Pugh A, c‐index/Akaike's information criterion (AIC) of prognostic predictive value of mALBI were superior to CPS (0.682/135.6 vs 0.652/138.7), while those of stopping LEN also showed that mALBI was better (0.575/447.3 vs 0.562/447.8). Additional analysis of patients with good mALBI (1/2a) revealed that time to stopping LEN was significantly shorter in those with the adverse event (AE) of appetite loss (any grade) than those without ( P = 0.006) and body mass index (BMI) was also lower in patients with that AE (20.3 ± 3.0 vs 23.6 ± 4.0kg/m 2 , P < 0.001), while patients with a hand‐foot skin reaction (any grade) showed good ORR/DCR (59.1%/86.4%) and longer TTP as compared to patients without ( P = 0.007). Conclusion Good hepatic function (mALBI 1/2a) is the best indication for LEN, while potential appetite loss in association with low BMI should be kept in mind in such cases.
