PURPOSE In a previous phase II trial, hepatic arterial infusion chemotherapy (HAIC) with infusional fluorouracil, leucovorin, and oxaliplatin (FOLFOX) yielded higher treatment responses than transarterial chemoembolization (TACE) in large unresectable hepatocellular carcinoma. We aimed to compare the overall survival of patients treated with FOLFOX-HAIC versus TACE as first-line treatment in this population. METHODS In this randomized, multicenter, open-label trial, adults with unresectable hepatocellular carcinoma (largest diameter ≥ 7 cm) without macrovascular invasion or extrahepatic spread were randomly assigned 1:1 to FOLFOX-HAIC (oxaliplatin 130 mg/m2, leucovorin 400 mg/m2, fluorouracil bolus 400 mg/m2 on day 1, and fluorouracil infusion 2,400 mg/m2 for 24 hours, once every 3 weeks) or TACE (epirubicin 50 mg, lobaplatin 50 mg, and lipiodol and polyvinyl alcohol particles). The primary end point was overall survival by intention-to-treat analysis. Safety was assessed in patients who received ≥ 1 cycle of study treatment. RESULTS Between October 1, 2016, and November 23, 2018, 315 patients were randomly assigned to FOLFOX-HAIC (n = 159) or TACE (n = 156). The median overall survival in the FOLFOX-HAIC group was 23.1 months (95% CI, 18.5 to 27.7) versus 16.1 months (95% CI, 14.3 to 17.9) in the TACE group (hazard ratio, 0.58; 95% CI, 0.45 to 0.75; P < .001). The FOLFOX-HAIC group showed a higher response rate than the TACE group (73 [46%] v 28 [18%]; P < .001) and a longer median progression-free survival (9.6 [95% CI, 7.4 to 11.9] v 5.4 months [95% CI, 3.8 to 7.0], P < .001). The incidence of serious adverse events was higher in the TACE group than in the FOLFOX-HAIC group (30% v 19%, P = .03). Two deaths in the FOLFOX-HAIC group and two in the TACE group were deemed to be treatment-related. CONCLUSION FOLFOX-HAIC significantly improved overall survival over TACE in patients with unresectable large hepatocellular carcinoma.

Purpose The aim of this retrospective study was to compare the clinical outcomes of pembrolizumab-lenvatinib-transarterial chemoembolization (TACE) versus lenvatinib-TACE sequential therapy in selected populations of Chinese patients with initially unresectable hepatocellular carcinoma (uHCC) harbouring programmed cell death ligand-1 (PD-L1) expression. Methods Consecutive patients with initial PD-L1-positive uHCC who received pembrolizumab-lenvatinib-TACE or lenvatinib-TACE sequential therapy were retrospectively identified from three medical institutions during 2016–2020. The primary endpoints included the rate of conversion therapy, defined as converting initially uHCC to hepatectomy, overall survival (OS), and progression-free survival (PFS); secondary endpoint was the frequency of key adverse events (AEs). Results In total, 220 consecutively recruited patients were retrospectively reviewed, 78 of whom were ineligible according to the current criteria, leaving 142 patients [pembrolizumab-lenvatinib-TACE: n = 70, median age 58 years (range 36–69) and lenvatinib-TACE: n = 72, 57 years (35–68)] who were eligible for the study. The median duration of follow-up was 27 months [95% confidence interval (CI), 26.3–28.7 months]. At the last follow-up, the rate of conversion therapy was 25.7% in the pembrolizumab-lenvatinib-TACE group and 11.1% in the lenvatinib-TACE group (p = 0.025). The median OS was 18.1 months (95% CI 16.5–20.7) in the pembrolizumab-lenvatinib-TACE group versus 14.1 months (95% CI 12.2–16.9) in the lenvatinib-TACE group [hazard ratio (HR) 0.56, 95% CI 0.38–0.83; p = 0.004]. A distinct difference in the median PFS interval between the groups was detected [9.2 months (95% CI 7.1–10.4) in the pembrolizumab-lenvatinib-TACE group vs. 5.5 months (95% CI 3.9–6.6) in the lenvatinib-TACE group (HR 0.60; 95% CI 0.39–0.91; p = 0.006)]. The rates of the key AEs assessed, which were hypertension, nausea, and rash, were higher in the pembrolizumab-lenvatinib-TACE group than in the lenvatinib-TACE group (all p < 0.05). Conclusion Among the selected populations of patients with initial PD-L1-positive uHCC, pembrolizumab-lenvatinib-TACE sequential therapy may have promising antitumour activity, with an acceptable conversion rate and a well-characterized safety profile.

Background: Lenvatinib is the first-line treatment for advanced hepatocellular carcinoma, but prognosis is still unsatisfactory. Recently, hepatic arterial infusion chemotherapy (HAIC), and immune checkpoint inhibitors showed promising results for advanced hepatocellular carcinoma. Considering different anti-malignancy mechanisms, combining these three treatments may improve outcomes. This study aimed to compare the efficacy and safety of lenvatinib, toripalimab, plus HAIC versus lenvatinib for advanced hepatocellular carcinoma. Methods: This was a retrospective study including patients treated with lenvatinib [8 mg (⩽60 kg) or 12 mg (>60 kg) once daily] or lenvatinib, toripalimab plus HAIC [LeToHAIC group, lenvatinib 0–1 week prior to initial HAIC, 240 mg toripalimab 0–1 day prior to every HAIC cycle, and HAIC with FOLFOX regimen (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, 5-fluorouracil bolus 400 mg/m2 on day 1, and 5-fluorouracil infusion 2400 mg/m2 for 46 h, every 3 weeks)]. Progression-free survival, overall survival, objective response rate, and treatment-related adverse events were compared. Results: From February 2019 to August 2019, 157 patients were included in this study: 71 in the LeToHAIC group and 86 in the lenvatinib group. The LeToHAIC group showed longer progression-free survival (11.1 versus 5.1 months, p < 0.001), longer overall survival (not reached versus 11 months, p < 0.001), and a higher objective response rate (RECIST: 59.2% versus 9.3%, p < 0.001; modified RECIST: 67.6% versus 16.3%, p < 0.001) than the lenvatinib group. In addition, 14.1% and 21.1% of patients in the LeToHAIC group achieved complete response of all lesions and complete response of the intrahepatic target lesions per modified RECIST criteria, respectively. Grade 3/4 treatment-related adverse events that were more frequent in the LeToHAIC group than in the lenvatinib group included neutropenia (8.5% versus 1.2%), thrombocytopenia (5.6% versus 0), and nausea (5.6% versus 0). Conclusions: Lenvatinib, toripalimab, plus HAIC had acceptable toxic effects and might improve survival compared with lenvatinib alone in advanced hepatocellular carcinoma.

Diabetic nephropathy is not only a common and severe microvascular complication of diabetes mellitus but also the leading cause of renal failure. Lotus ( Nelumbo nucifera ) possesses antioxidative and anticancer properties. The present study aimed to investigate the antidiabetic and renoprotective effects of N. nucifera leaf extract (NLE) in a rat model of type 2 diabetic mellitus. Male Sprague–Dawley rats with type 2 diabetes induced by a high-fat diet (HFD)/streptozotocin (STZ) were treated with NLE at dosages of 0.5% and 1% (w/w) daily for 6 weeks. At the end of the experimental period, body weight, serum glucose levels, insulin levels, and kidney function were assessed. Furthermore, antioxidant enzyme and lipid peroxide levels were determined in the kidney, and histopathological examination was performed using hematoxylin and eosin staining, periodic acid Schiff staining, and Masson trichrome staining. To shed light on the molecular mechanism underlying the functioning of NLE, mouse glomerular mesangial cells (MES-13) treated with high glucose (HG, 25 mM glucose) were chosen as a model for an examination of the signal transduction pathway of NLE. The results revealed that NLE improved diabetic kidney injury by reducing blood glucose, serum creatinine, and blood urea nitrogen levels and enhanced antioxidant enzyme activities in kidney tissue. Treatment with NLE significantly reduced the malondialdehyde and 8-hydroxy-2-deoxyguanosine levels and increased serum insulin levels; expression of renal superoxide dismutase, catalase, and glutathione peroxidase activities; and glutathione content. Histological studies have also demonstrated that NLE treatment inhibited the dilation of Bowman’s capsule, which confirmed its renoprotective action in diabetes. In addition, treatment with NLE and its major component quercetin 3-glucuronide attenuated 25 mM HG-induced suppressed nuclear factor erythroid 2-related factor 2 and antioxidant enzyme expression in MES-13 cells. Collectively, these findings indicate that NLE may have antidiabetic and renoprotective effects against HFD/STZ-induced diabetes, at least in part, through antioxidative pathways.

BackgroundTivantinib has been described as a highly selective inhibitor of MET and is currently in a phase III clinical trial for the treatment of hepatocellular carcinoma (HCC). However, the mechanism of tivantinib anti-tumor effect has been questioned by recent studies.ResultsWe show that tivantinib indiscriminately inhibited MET dependent and independent HCC cells proliferation. In contrast, other MET inhibitors, JNJ-38877605 and PHA-665752, just specifically inhibited the growth of MET dependent HCC cells. Tivantinib neither inhibit constitutive MET phosphorylation nor HGF-induced MET phosphorylation in HCC cells. In the microtubule polymerization analysis, tivantinib affected microtubule dynamics by a mechanism as a microtubule depolymerizer. Interesting, unlike other microtubule-targeting agents, paclitaxel and vincristine, tivantinib showed similar anti-proliferative activity in parental and multidrug-resistant cells. Further studies demonstrated that tivantinib induced a G2/M arrest and promoted apoptosis by both intrinsic and extrinsic pathway. The in vivo efficacy evaluation showed that tivantinib exhibited a good anti-tumor growth activity with anti-proliferative and pro-apoptotic effects.ConclusionsThe potent anti-tumor activity of tivantinib in HCC was achieved by targeting microtubule. Tivantinib treatment for patients with HCC should not be selected based on MET status.
