Abstract

Background: Data concerning the use of lenvatinib in very old patients (≥ 80 years) are limited, although the incidence of hepatocellular carcinoma (HCC) in this patient population is constantly increasing. Objective: This analysis aimed to evaluate the efficacy and safety of lenvatinib in a large cohort of very old patients (≥ 80 years) with unresectable HCC. Patients and Methods: The study was conducted on a cohort of 1325 patients from 46 centers in four Western and Eastern countries (Italy, Germany, Japan, and the Republic of Korea) who were undergoing first-line treatment with lenvatinib between July 2010 and February 2022. Patients were stratified according to age as very old (≥ 80 years) and not very old (< 80 years). Results: The median overall survival (OS) was 15.7 months for patients < 80 years old and 18.4 months for patients ≥ 80 years old [hazard ratio (HR) = 1.02, 95% confidence interval (CI) 0.84–1.25, p = 0.8281]. Median progression free survival (PFS) was 6.3 months for patients < 80 years old and 6.5 months for patients ≥ 80 years old (HR = 1.07, 95% CI 0.91–1.25, p = 0.3954). No differences between the two study groups were found in terms of disease control rate (DCR; 80.8% versus 78.8%; p = 0.44) and response rate (RR; 38.2% versus 37.9%; p = 0.88). Patients < 80 years old experienced significantly more hand–foot skin reaction (HFSR) grade ≥ 2 and decreased appetite grade ≥ 2. Conversely, patients ≥ 80 years old experienced significantly more fatigue grade ≥ 2. In the very old group, parameters associated with prognosis were AFP, albumin–bilirubin (ALBI) grade, Barcelona Clinic Liver Cancer (BCLC), and Child–Pugh score. BCLC stage was the only independent predictor of overall survival (OS; HR = 1.59, 95% CI 1.11–2.29, p = 0.01115). Conclusions: Our study highlights the same efficacy and safety of lenvatinib between very old and not very old patients.
