RESUMEN
AIM: Lenvatinib mesylate (LEN) is an oral tyrosine kinase inhibitor used to treat various cancers, including hepatocellular carcinoma (HCC). HCC treatment with LEN is associated with a very high incidence of adverse events. This study was aimed at investigating the incidence of LEN-induced palmar-planter erythrodysesthesia syndrome (PPES) and its relationship with patient demographics by analyzing clinical laboratory data of LEN-treated patients with HCC. METHODS: This was a single-centre, retrospective study of patients with HCC who received LEN between April 19, 2018, and September 30, 2020. The observation period was from 1 week before the start of LEN administration to 1 month after the end of administration. RESULTS: Overall, 75 patients with HCC were enrolled. LEN-induced PPES was found in 48.0% (36/75 patients). In these patients, alkaline phosphatase (ALP), γ-Glutamyl transpeptidase (γ-GTP) and monocytes (MONO) were significantly high (ALP: p = 1.32 × 10-3, γ-GTP: p = 4.25 × 10-3 and MONO: p = 0.013). The cut off values of ALP, γ-GTP and MONO for LEN-induced PPES were estimated at 573 U/L, 89 U/L, and 310 counts/µL, respectively. In the multivariate analysis, γ-GTP and MONO were independent risk factors for LEN-induced PPES. CONCLUSIONS: High γ-GTP and high MONO were risk factors for LEN-induced PPES.

INTRODUCTION: Lenvatinib mesylate (LEN) is an orally administered tyrosine kinase inhibitor used for the treatment of various cancers, including hepatocellular carcinoma (HCC). HCC treatment with LEN is associated with a very high incidence of adverse events, especially hypothyroidism. This study investigated the incidence of hypothyroidism due to LEN and the relationships between hypothyroidism incidence and patient demographics by analyzing clinical laboratory data from HCC patients treated with LEN. METHODS: This was a single-center, retrospective study of HCC patients who received LEN between April 19, 2018, and September 30, 2020. The observation period was from 1 week before the start of LEN administration to 1 month after the end of administration. RESULTS: In total, 61 patients with HCC were enrolled. High-grade hypothyroidism (CTCAE Grade 2-3) was found in 36.1% (22/61 patients). In high-grade hypothyroidism, eosinophil (EOSINO) count was significantly low (p = 0.029). The cutoff value of EOSINO count was estimated to be approximately 150/µL. The adjusted odds ratios of high-grade hypothyroidism for current smoking and EOSINO count <150/µL were 0.237 (95% confidence interval: 0.063-0.893) and 4.219 (95% confidence interval: 1.119-15.92), respectively. CONCLUSION: The results showed that noncurrent smoking and EOSINO count <150/µL are risk factors for LEN-induced high-grade hypothyroidism.
