Risk factors for lenvatinib‐induced hypertension in patients with hepatocellular carcinoma: A retrospective study.

Aims Methods Results Conclusion Lenvatinib mesylate (LEN) is an orally administered tyrosine kinase inhibitor used to treat various cancers, including hepatocellular carcinoma (HCC). LEN therapy for HCC is associated with a high incidence of adverse events, including hypertension (HTN). However, the risk factors associated with LEN therapy remain unclear. This study investigated the incidence of LEN‐induced HTN (LENiHTN), and the relationship between HTN incidence and patient demographics in patients with HCC receiving LEN therapy.This was a single‐centre, retrospective study of patients with HCC who received LEN therapy between 19 April 2018 and 30 September 2020. The observation period was from 1 week before the start to 1 month after the end of LEN administration.Seventy‐five patients with HCC were enrolled. Any grade LENiHTN was found in 74.7% of patients. Among patients with LENiHTN, the use of 2 or more antihypertensive agents before starting LEN was less common (<italic>P</italic> = .007); serum potassium (K) and albumin–bilirubin score (ALBI) were lower (<italic>P</italic> = .013 and 0.038, respectively); and albumin (Alb) was higher (<italic>P</italic> = .025). The cut‐off values of K, Alb and ALBI for HTN were estimated at 4.1 mEq L−1, 3.1 g dL−1 and −1.736, respectively. In the multivariable analysis, low K (adjusted HR: 2.078) and low ALBI (adjusted HR: 2.845) were independent risk factors for LENiHTN.Low K, high Alb and low ALBI were independent risk factors for LENiHTN. Systematic evaluation of HTN risk and early intervention for HTN prevention among high‐risk patients can markedly enhance LEN therapy efficacy and use. [ABSTRACT FROM AUTHOR]
