Abstract
Introduction Lenvatinib (LEN) is the standard treatment for hepatocellular carcinoma (HCC). In clinical practice, gastrointestinal (GI) symptoms such as fatigue and loss of appetite often lead to dose reduction or treatment discontinuation. This study aimed to identify the predictors of patients who will experience dose reduction or treatment discontinuation owing to fatigue or GI symptoms during LEN treatment for HCC. Methods We retrospectively identified 99 patients who received LEN at the Ogaki Municipal Hospital (Ogaki, Japan) between April 2018 and December 2023. To investigate the risk factors for treatment discontinuation or dose reduction due to fatigue or GI symptoms during LEN administration, patients were divided into two groups based on whether treatment discontinuation or dose reduction occurred due to fatigue or GI symptoms during LEN administration (37 patients) or not (62 patients). We compared baseline characteristics between the two groups. Results Multivariate analysis revealed that body weight (odds ratio 4.310, 95% confidence interval 1.380–13.500; P = 0.002) was an independent risk factor that significantly contributed to treatment discontinuation or dose reduction owing to fatigue or GI symptoms during LEN administration. The cut-off value calculated using the body weight curve was 55.0 kg. Using this cutoff value, the sensitivity and specificity of body weight to detect treatment discontinuation or dose reduction due to fatigue or GI symptoms during LEN administration were 83.9% and 56.8%, respectively. Conclusion In clinical practice, patients weighing less than 55 kg who start with a full dose will likely experience weight loss or discontinuation during treatment.
