Purpose To assess the safety, efficacy and prognostic impact of clinical factors related to lenvatinib treatment in Child-Pugh class A (CP-A) and class B (CP-B) patients with unresectable hepatocellular carcinoma (u-HCC). Methods Patients with u-HCC who were treated with lenvatinib at multiple centers in Japan were retrospectively analyzed for treatment outcomes according to their respective CP status. Radiological objective response (OR) was assessed using modified response evaluation criteria in solid tumors (mRECIST) guidelines. Results Baseline demographic parameters were comparable between 126 (69.6%) patients with CP-A disease and 55 patients (30.4%) with CP-B disease. Frequency of lenvatinib-related adverse events, including decreased appetite (P=0.034), diarrhea (P=0.040), elevated serum bilirubin (P=0.016) and vomiting (P=0.009), were higher in CP-B than in CP-A patients. Relative dose intensity (RDI) was significantly higher in CP-A (0.69) than CP-B patients (0.50, P <0.001). Furthermore, OR rate (44.0%) was markedly higher in CP-A5 patients as compared to CP-A6 (25.5%), CP-B7 (22.2%), and CP-B8 patients (5.3%), respectively (P=0.002). In multivariable analysis, performance status (0 vs 1, 2, P=0.026), CP class (A vs B, P=0.045) and RDI (≥0.7 vs <0.7, P=0.034) were identified as factors associated with response to lenvatinib treatment. Overall survival (OS) at 12 months was significantly different between CP-A (66.3%) and CP-B patients (30.0%, P=0.002), and between CP 5–7 (59.2%) and CP 8 patients (34.8%, P=0.003). In multivariable analysis, CP class (A vs B, P=0.007) and Barcelona clinic liver cancer (BCLC) stage (B vs C, P=0.002) were associated with OS following lenvatinib treatment. Conclusion Lenvatinib treatment offers significant benefits in patients with good liver function in real-world practice. The various characteristics identified in this study might be helpful as clinical predictors of response to lenvatinib and survival in clinical practice. Further studies are required to address eligibility for lenvatinib treatment in CP 7 patients.
Purpose: To assess the impact of clinical factors on the safety and efficacy of atezolizumab plus bevacizumab (ATZ + BV) treatment in patients with unresectable hepatocellular carcinoma (u-HCC).Method: Ninety-four u-HCC patients who were treated with ATZ + BV at multiple centers were enrolled. We defined Child-Pugh (CP)-A patients who received ATZ + BV treatment as a first line therapy as the 'meets the broad sense of the IMbrave150 criteria' group (B-IMbrave150-in, n = 46), and patients who received ATZ + BV treatment as a later line therapy or CP-B patients (regardless of whether ATZ + BV was a first line or later line therapy) as the B-IMbrave150-out group (n = 48). Patients were retrospectively analyzed for adverse events (AEs) and treatment outcomes according to their clinical characteristics, including neutrophil lymphocyte ratio (NLR) at baseline. Results:The overall incidence of AEs was 87.2% (82/94 patients). The frequency of interruption of ATZ + BV treatment due to fatigue was higher in CP-B than CP-A patients (p = 0.030). Objective response (OR) rates of the B-IMbrave150-in group (28.3%, 39.1%) were significantly higher than those of the B-IMbrave150-out group (8.3%, 18.8%; p = 0.0157, 0.0401) using Response Evaluation Criteria in Solid Tumors (RECIST) and modified RECIST, respectively. In multivariate analysis, NLR (hazard ratio (HR), 4.591; p = 0.0160) and B-IMbrave150 criteria (HR,
Aims To assess the safety, efficacy, and prognostic impact of clinical factors associated with lenvatinib treatment in highly advanced hepatocellular carcinoma (HCC) with tumor thrombus in the main portal vein trunk (VP4) or tumor with more than 50% liver occupation (tm50%LO). Methods A total of 61 highly advanced HCC patients (41 patients with tm50%LO and 20 patients with VP4) who were treated with lenvatinib at multicenter were enrolled and retrospectively analyzed for treatment outcomes according to their clinical status, including tumor morphology. Results The most frequent grade ≥3 adverse event in tm50%LO HCC was elevated aspartate aminotransferase (17.1%). Objective response rates were 37.5% and 0% in tm50%LO HCC patients with Child–Pugh grade (CP)‐A and CP‐B, respectively, and 26.7% and 0% in VP4 HCC patients with CP‐A and CP‐B, respectively. Estimated median progression‐free survival and overall survival were 132 days and 229 days, and 101 days and 201 days in patients with tm50%LO and VP4, respectively. In multivariate analysis, modified albumin‐bilirubin grade (hazard ratio 0.372, 95% CI 0.157–0.887; p = 0.0241) and tumor morphology (hazard ratio 0.322, 95% CI 0.116–0.889; p = 0.0287) were independently associated with progression‐free survival in patients with tm50%LO HCC. In VP4 HCC, median progression‐free survival was worse in CP‐B (57 days) than in CP‐A patients (137 days, p = 0.0462). Conclusions Lenvatinib treatment offers a benefit in highly advanced HCC (tm50%LO or VP4) patients with good liver function or nodular‐type tumor. The various characteristics identified in this study might be useful as indicators of lenvatinib treatment in highly advanced HCC with tm50%LO or VP4, which are considered very refractory cancers.
We report two cases of schwannoma displaying marked cystic changes; one in the temporalis muscle and one in the submandibular space. The first patient, a 44-year-old male, presented after complaining of a swelling rapidly increasing in size in the left temporal region. Computed tomography (CT) indicated a low-density area surrounded by soft tissue. Magnetic resonance imaging (MRI) revealed signal hypointensity on T1 weighted imaging and strong signal hyperintensity on T2 weighted imaging. The extirpated tumour specimen measured 58 mm x 58 mm x 30 mm. Histopathological examination identified schwannoma, comprising spindle cell proliferation in a palisading pattern with obvious cystic changes. The second case involved a 46-year-old female who presented with swelling of the right submandibular region. Panoramic radiography and lateral oblique mandible projection, which were used together with conventional sialography of the submandibular gland, revealed the so-called "ball in hand" appearance of the submandibular gland, and contrast-enhanced CT identified a lesion of 30 mm diameter with a well-defined annular margin and homogeneous low-density near the tumour centre. Benign pleomorphic adenoma was suspected, but histopathological examination identified schwannoma, predominantly comprising Antoni B type tissue.
Aim Lenvatinib is an oral, multitargeted, tyrosine kinase inhibitor, which suppress tumor angiogenesis and tumor progression. It was non‐inferior to sorafenib in overall survival in untreated advanced hepatocellular carcinoma (HCC). Sorafenib had a beneficial effect on portocollateral circulation with portal hypertension in translating and clinical studies. However, the hemodynamic effects of lenvatinib appear to be different from those of sorafenib because the efficacy of lenvatinib for vascular endothelial growth factor receptors and fibroblast growth factor receptors is different from that of sorafenib. This study was prospectively performed to evaluate the portal hemodynamic effect of lenvatinib in patients with advanced HCC using duplex Doppler ultrasonography. Methods In total, 28 Child‐Pugh class A or B patients with advanced HCC received lenvatinib depending on body weight daily for 2 weeks. Primary outcomes were changes in the hemodynamics of the portal venous system using duplex Doppler ultrasonography before and after the 2‐week administration of lenvatinib. Results The portal venous flow velocity (cm/s) significantly reduced (27 ± 12.1 vs. 22.6 ± 8.0, P = 0.019), while portal venous area (cm2) did not change after the 2‐week administration (0.80 ± 0.36 vs. 0.82 ± 0.27, P = 0.665). Therefore, the congestion index (portal venous area/portal venous flow velocity), which reflects the pathophysiological hemodynamics of the portal venous system significantly worsened (0.037 ± 0.025 vs. 0.043 ± 0.024, P = 0.045). Conclusions Considering that this was a short‐term study, because lenvatinib could be an agent that aggravates portal hypertension, it will be necessary to verify its clinical effects for portal hypertension in future studies.
Predictive biomarkers of the response of hepatocellular carcinoma (HCC) to Lenvatinib therapy have not yet been clarified. The aim of this study was to identify clinically significant biomarkers of response to Lenvatinib therapy, to target strategies against HCC. Levels of circulating angiogenic factors (CAFs) were analyzed in blood samples collected at baseline and after introducing lenvatinib, from 74 Child-Pugh class A HCC patients who received lenvatinib. As CAF biomarkers, serum vascular endothelial growth factor (VEGF), fibroblast growth factor 19 (FGF19), FGF23, and angiopoietin-2 (Ang-2) were measured using enzyme-linked immunosorbent assays. Results: Significantly increased FGF19 (FGF19-i) levels and decreased Ang-2 (Ang-2-d) levels were seen in Lenvatinib responders as compared to non-responders (ratio of FGF19 level at 4 weeks/baseline in responders vs. non-responders: 2.09 vs. 1.32, respectively, p = 0.0004; ratio of Ang-2 level at four weeks/baseline: 0.584 vs. 0.810, respectively, p = 0.0002). Changes in FGF23 and VEGF levels at four weeks versus baseline, however, were not significantly different in responders versus non-responders. In multivariate analysis, the combination of serum FGF19-i and Ang-2-d was the most independent predictive factor for Lenvatinib response (Odds ratio, 9.143; p = 0.0012). Furthermore, this combination biomarker showed the greatest independent association with progression-free survival (Hazard ratio, 0.171; p = 0.0240). Early changes in circulating FGF19 and Ang-2 levels might be useful for predicting clinical response and progression-free survival in HCC patients on Lenvatinib therapy.
Aim There are limited data from prospective studies showing the clinical usefulness of the new criteria for sarcopenia in liver disease produced by the Japan Society of Hepatology. Therefore, we aimed to evaluate the clinical usefulness of this new criteria for prognosis in cirrhotic patients. Methods This prospective study was performed at six centers. The 300 enrolled patients, aged more than 20 years with liver cirrhosis, were evaluated over a 3‐year period for skeletal muscle mass index and grip strength. Sarcopenia was defined according to the Japan Society of Hepatology criteria by grip strength and computed tomography‐based skeletal muscle mass index values. We investigated the correlation between sarcopenia and the survival rate of cirrhotic patients. Results Among the 300 assessed patients there were 99 (33%) patients with sarcopenia. The number of deaths in the sarcopenia and non‐sarcopenia groups was 34 (34.3%) and 38 (18.9%), respectively (p = 0.002). Multivariate analysis confirmed that sarcopenia, decompensated phase, albumin‐bilirubin grade, and hepatocellular carcinoma (HCC) stage 3/4 were independent factors correlated with death in patients with liver cirrhosis during the observation period. The interaction between sarcopenia and the presence of HCC was statistically significant (p < 0.001), and the presence of HCC had the highest hazard ratio of 6.665 for deaths in cirrhotic patients when non‐sarcopenia and the absence of HCC were used as references. Conclusions The new Japan Society of Hepatology criteria for sarcopenia are accurate predictors of poor prognosis in patients with liver cirrhosis.
