RESUMEN
BACKGROUND/AIM: Lenvatinib (LEN) has been approved as an oral tyrosine kinase inhibitor for advanced hepatocellular carcinoma (HCC). However, in some patients, LEN does not provide adequate therapeutic benefits. In this study, we examined the factors that affect the therapeutic response to LEN. PATIENTS AND METHODS: This retrospective cohort study involved patients with HCC who received LEN therapy at Osaka Metropolitan University Hospital. We used the delivered dose intensity to body surface area ratio for 60 days (2M-DBR) as an index of the therapeutic response. RESULTS: This study included 83 patients divided into two groups, the high 2M-DBR group (47 patients, 56.7%) and low 2M-DBR group (36 patients, 43.4%). Univariate analysis showed that Child-Pugh class, C-reactive protein, and prognostic nutrition index (PNI) were significant factors for high 2M-DBR. Furthermore, multivariate logistic regression analysis revealed that a PNI>39.15 was significantly associated with high 2M-DBR. CONCLUSION: A PNI cut-off value of less than 39.15 may indicate a poor response to LEN therapy. PNI, an easy, simple, and inexpensive tool, may be useful in identifying patients in need of early intervention.

The use of semi-solid enteral nutrients plays an extremely important role in accurate nutrition management. In the present study, we compared the pharmacokinetic profile of orally administered carbamazepine (CBZ) in rats treated with liquid RACOL®, semi-solid RACOL®, and HINE E-gel®, which are enteral nutrients marketed in Japan. Since liquid and semi-solid formulations are both marketed in Japan for RACOL®, liquid RACOL® was orally administered to control rats. The serum concentration of CBZ at each sampling point was lower in the semi-solid RACOL®-treated group than in the liquid RACOL®-treated group. No significant differences were observed in the pharmacokinetic behavior of CBZ between the semi-solid RACOL®-treated and HINE E-gel®-treated groups. Regarding pharmacokinetic parameters, the impact of the area under the curve (AUC0â5h) was the liquid RACOL® group > the semi-solid RACOL® group ≈ the HINE E-gel® group. Therefore, we concluded that serum concentrations of CBZ were lower when concurrently treating with semi-solid enteral nutrients than when simultaneously processing liquid enteral nutrients.
