Management of Cirrhotic Ascites under the Add-on Administration of Tolvaptan

Tolvaptan is a recently available diuretic that blocks arginine vasopressin receptor 2 in the renal collecting duct. Its diuretic mechanism involves selective water reabsorption by affecting the water reabsorption receptor aquaporin 2. Given that liver cirrhosis patients exhibit hyponatremia due to their pseudo-aldosteronism and usage of natriuretic agents, a sodium maintaining agent, such as tolvaptan, is physiologically preferable. However, large scale studies indicating the patients for whom this would be effective and describing management under its use have been insufficient. The appropriate management of cirrhosis patients treated with tolvaptan should be investigated. In the present review, we collected articles investigating the effectiveness of tolvaptan and factors associated with survival and summarized their management reports. Earlier administration of tolvaptan before increasing the doses of natriuretic agents is recommended because this may preserve effective arterial blood volume

History of Transcatheter Arterial Chemoembolization Predicts the Efficacy of Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma Patients

This study sought to identify factors that are predictive of a therapeutic response to hepatic arterial infusion chemotherapy (HAIC) by focusing on the number of prior transcatheter arterial chemoembolization (TACE) sessions. To determine the parameters predicting a good response to HAIC, we retrospectively analyzed 170 patients with hepatocellular carcinoma (HCC) who received HAIC regimens comprising low-dose cisplatin combined with 5-fluorouracil (LFP) or cisplatin (CDDP) for the first time. In both the LFP and CDDP regimens, the response rates were significantly lower in patients with three or more prior TACE sessions than in those with two or fewer prior TACE sessions (LFP 57% versus 28%; p=0.01, CDDP 27% versus 6%; p=0.01). Multivariable logistic regression analysis revealed that the number of prior TACE sessions (≥ 3) was significantly associated with non-responder status (odds ratio 4.17, 95% Confidence Interval (CI) 1.76-9.86) in addition to the HAIC regimen. Multivariable analysis using the Cox proportional hazards model revealed that a larger number of prior TACE sessions (≥ 3) was a significant risk factor for survival (hazard ratio 1.60, 95% CI 1.12-2.29) in addition to Child-Pugh class, serum alpha-fetoprotein concentration, and maximum diameter of HCC. HCC patients who receive fewer prior TACE sessions (≤ 2) were found to be better responders to HAIC

Noninvasive Demonstration of Dual Coronary Artery Fistulas to Main Pulmonary Artery with 64-Slice Multidetector-Computed Tomography: A Case Report

Coronary artery fistulas, including coronary pulmonary fistulas, are usually discovered accidently among the adult population when undergoing invasive coronary angiographies. We report here a 58-year-old woman with dual fistulas originating from the left anterior descending coronary artery and right coronary sinus to the main pulmonary artery, demonstrating noninvasively with multidetector-computed tomography (MDCT) and transthoracic echocardiography (TTE)

The Early Decline of alpha-Fetoprotein and Des-gamma-Carboxy Prothrombin Predicts the Response of Hepatic Arterial Infusion Chemotherapy in Hepatocellular Carcinoma Patients

Introduction: Molecular targeting drugs are recommended as second-line treatment for intrahepatic advanced hepatocellular carcinoma (HCC). However, in Asia, hepatic arterial infusion chemotherapy (HAIC) is also considered as a second-line treatment because it improves the survival of responders. The aim of this study was to predict responders and non-responders to HAIC with low-dose cisplatin plus 5-fluorouracil (LFP) using tumor markers. Objective and Methods: The data of 47 patients who received LFP for the first time in our hospital were analyzed retrospectively. We evaluated the association between treatment response by Response Evaluation Criteria in Solid Tumors and the changing ratio of the serum concentration of alpha-fetoprotein (AFP),Lens culinarisagglutinin-reactive fraction of AFP (AFP-L3), and des-gamma-carboxy prothrombin (DCP) 2 weeks after LFP initiation. Results: The number of patients showing a complete response (CR), a partial response (PR), stable disease (SD), and progressive disease (PD) was 0 (0%), 20 (43%), 18 (38%), and 9 (19%), respectively. The AFP ratio showed significant positive correlations for PR vs. SD (p= 0.004) and PR vs. PD (p= 0.003). The DCP ratio correlated significantly for PR vs. SD (p= 0.02). The optimal cutoff values for responders were 0.79 for the AFP ratio and 0.53 for the DCP ratio. Prediction using both or either cutoff value showed 93% sensitivity, 53% specificity, a 94% negative predictive value, and a 57% positive predictive value. Conclusion: Optimal cutoff values for AFP and DCP ratios enable prediction of nonresponders to HAIC with LFP. This simple and early assessment method allows the use of HAIC and molecular targeting drugs for HCC treatment

Decreased Serum Antioxidant Marker is Predictive of Early Recurrence in the Same Segment after Radical Ablation for Hepatocellular Carcinoma

Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is a promising method for controlling tumors, although it does not entirely eliminate recurrence. Oxidative stress is associated with the progression of hepatocarcinogenesis, while also acting as an anticancer response. The objective of the present study was to investigate the factors influencing post-RFA outcomes. We recruited 235 newly diagnosed HCC patients who received RFA for single tumors. The patients with recurrence were sub-grouped into early and segmental recurrence groups. The characteristics of the sub-grouped patients were evaluated, including by measuring oxidative stress marker reactive oxygen metabolites and antioxidant marker OXY-adsorbent tests. The factors associated with poor survival were a high Child-Pugh score and early recurrence within 2 years in the same segment. The patients who experienced recurrence within 2 years in the same segment showed a larger tumor diameter than did others. According to a multivariate analysis, the OXY values were also significantly low in these patients. In conclusion, maintaining the antioxidant reservoir function with a high OXY value might be necessary to prevent early recurrence within the RFA-treated segment

Metastases of soft tissue sarcoma to the liver: A Historical Cohort Study from a Hospital-based Cancer Registry

Background: Hepatic metastasis of soft tissue sarcoma is rare compared to lung metastasis, and the literature is scarce. We examined the risk of hepatic metastasis according to the site of occurrence and histological type. Methods: From a Hospital-based Cancer Registry, 658 patients registered between 2007 and 2017 with soft tissue sarcomas were evaluated. The exclusion criteria were gastrointestinal stromal tumors, tumors of unknown origin, and follow-up periods of less than 1 month. SPSS 25 was used for statistical analysis. Results: The risk of hepatic metastasis was significantly higher in the retroperitoneum (HR, 5.981; 95% CI, 2.793-12.808) and leiomyosarcoma (HR, 4.303; 95% CI, 1.782-10.390). Multivariate analysis showed that the risk of hepatic metastasis as first distant metastasis was high in leiomyosarcoma (HR, 4.546; 95% CI, 2.275-9.086) and retroperitoneal onset (HR, 4.588; 95% CI, 2.280-9.231). The 2-year survival rate after hepatic metastasis was 21.7%. Conclusions: The onset of hepatic metastasis indicates a poor prognosis. However, hepatic metastasis from retroperitoneal sarcoma and leiomyosarcoma may be the first distant metastasis in some cases. For retroperitoneal sarcoma and leiomyosarcoma, additional screening for hepatic metastasis such as contrast CT should be considered during staging and follow-up after treatment.ArticleCancer medicine 17(17) : 6159-6165(2020)journal articl

Prediction of the prognosis of advanced hepatocellular carcinoma by TERT promoter mutations in circulating tumor DNA

Background and Aim Human telomerase reverse transcriptase (TERT) promoter mutations were the most prevalent mutations in patients with hepatocellular carcinoma (HCC). We tried to detect the mutations with plasma circulating tumor DNA (ctDNA) in patients with advanced HCC and elucidated their clinical utility. Methods Circulating tumor DNA in plasma was extracted from 130 patients with advanced HCC who were treated with systemic chemotherapy (n = 86) or transcatheter arterial chemoembolization (n = 44), and TERT promoter mutations were examined with digital droplet polymerase chain reaction. The correlations between these mutations and the clinical outcome of patients were analyzed. Results Of the 130 patients examined, 71 patients (54.6%) were positive for TERT promoter mutations in ctDNA, of which 64 patients were −124bp G > A and 10 were −146bp G > A. The presence of TERT promoter mutations was correlated with large intrahepatic tumor size (P = 0.05) and high des‐gamma carboxyprothrombin (P = 0.005). Overall survival of the patients with the mutations was significantly shorter than those without them (P Conclusions TERT promoter mutations in ctDNA were associated with short survival and could be a valuable biomarker for predicting the prognosis of patients with advanced HCC

The Role of c-fos in Cell Death and Regeneration of Retinal Ganglion Cells

PURPOSE. To investigate the effect of c-fos on apoptotic cell death and regeneration of damaged retinal ganglion cells (RGCs) in tissue culture of retinal explants. METHODS. Retinas from transgenic mice carrying the exogenous c-fos gene under the control of the interferon (IFN)-␣/␤ inducible Mx-promoter (Mx-c-fos), c-fos-deficient mice, and littermate control mice were dissected and cultured in a threedimensional collagen gel culture system, followed by an analysis of TdT-dUTP terminal nick-end labeling (TUNEL) staining and measurement of neurites that emerged from explants. RESULTS. Compared with littermate control mice, Mx-c-fos transgenic animals showed a higher ratio of TUNEL positivity in the RGC layer from early in the culture period that correlated with the small number of regenerating neurites. In contrast, the c-fos-null mutated mice showed a still-lower ratio of TUNEL-positive cells. Nevertheless, the number of regenerating neurites was significantly lower in the initial phase, although the drastic increase in density of neurite regeneration was observed in the late period of culture. CONCLUSIONS. These findings suggest that c-fos is involved in both apoptotic cell death and regeneration of damaged RGCs. Elucidation of the precise c-fos-mediated cascade involved in RGC apoptosis and regeneration is significant in realizing neuronal survival and regeneration. (Invest Ophthalmol Vis Sci

Predictive Factors for Successful Vaccination Against Hepatitis B Surface Antigen in Patients Who Have Undergone Orthotopic Liver Transplantation

Post-orthotopic liver transplantation (OLT) hepatitis B recurrence is well-controlled with a nucleos(t)ide analogue and hepatitis B immunoglobulin (HBIG) combination, but the high cost and the potential risk of unknown infection associated with HBIG remain unresolved issues. Low-cost recombinant hepatitis B virus (HBV) vaccine administration is a potential solution to these problems. We retrospectively analyzed the rate and predictive factors of HBV vaccine success in 49 post-OLT patients: liver cirrhosis-type B (LC-B), n=28 patients; acute liver failure-type B (ALF-B), n=8; and non-HBV-related end-stage liver disease (non-B ESLD) who received a liver from anti-hepatitis B core antibody-positive donors, n=13. A positive anti-hepatitis B surface antibody response was achieved in 29% (8/28) of the LC-B group, 88% (7/8) of the ALF-B group, and 44% (4/9) of the adult non-B ESLD group. All four non-B ESLD infants showed vaccine success. The predictive factors for a good response in LC-B were young age, marital donor, and high donor age. ALF-B and non-B ESLD infants are thus good vaccination candidates. LC-B patients with marital donors are also good candidates, perhaps because the donated liver maintains an efficient immune memory to HBV, as the donors had already been infected in adulthood and showed adequate anti-HBV immune responses
