Efficacy of glass membrane emulsification device in conventional transarterial chemoembolization for hepatocellular carcinoma: a preliminary study.

BACKGROUND: Transarterial chemoembolization (TACE) is the standard treatment for Barcelona Clinic Liver Cancer (BCLC)-B hepatocellular carcinoma (HCC). A novel glass membrane emulsification device (GMD) produces a high percentage of water/oil emulsions with homogeneous and stable droplets. There are few reports on the efficacy of GMD-conventional-TACE (GMD-c-TACE); therefore, we aimed to evaluate the effectiveness of GMD-c-TACE. METHODS: Seventy-one patients with HCC with tumor diameter <5 cm who underwent c-TACE with and without GMD were included in this study to investigate local recurrence and hepatic functional reserve. RESULTS: The local recurrence rates of TACE without GMD were 3.0% at 6 months, 16.7% at 12 months, and 35.0% at 18 months, around where it plateaued. In contrast, the local recurrence rates in the GMD-c-TACE group were 0.0% at 12 months and 15.4% at 18 months, respectively. Thus, GMD-c-TAE had a significantly lower local recurrence. ALBI score of c-TACE with GMD significantly preserved hepatic reserve. Multivariate analysis showed that GMD-c-TACE could suppress local recurrence and maintain hepatic reserve. CONCLUSIONS: GMD-c-TACE allows dense lipiodol accumulation in the tumor and the attainment of good local control. Additionally, in vitro evaluation of the sustained release properties of GMD, the inhibition of the release of anticancer drugs may lead to maintain hepatic reserve. GMD-c-TACE is useful in preventing local recurrence and is expected to become the standard treatment form of c-TACE in the future.

Analysis of predictors after partial splenic embolization for thrombocytopenia with liver cirrhosis.

Blood transfusion, splenectomy, and partial splenic embolization (PSE) are generally performed for thrombocytopenia in patients with cirrhosis. Recently, thrombopoietin (TPO) agonists have become available, and investigations of patients who would benefit from them are necessary. Therefore, it is important to understand the fluctuations in cytokine levels associated with PSE. Therefore, fluctuations in platelet-associated immunoglobulin G (PAIgG), interleukin 6 (IL-6), and TPO levels with PSE were analyzed in this study. The study included 110 patients with liver cirrhosis and thrombocytopenia, with the aim of improving platelet counts. Fluctuations in PAIgG, IL-6, and TPO levels were investigated. The average splenic embolization ratio was 58.0% in patients with PSE. The platelet count rose significantly from 6.95 [5.40, 8.60] × 104/mL to 14.05 [10.43, 18.05] × 104/mL (P < .01), IL-6 rose significantly from 3.56 [2.53, 7.33] pg/mL to 18.90 [9.17, 32.95] pg/mL (P < .01), TPO rose significantly from 0.82 [0.52, 1.21] fmol/mL to 1.58 [0.97, 2.26] fmol/mL (P < .01), and PAIgG decreased significantly from 64.20 [38.33, 118.75] ng/107 cells to 37.50 [22.25, 70.00] ng/107 cells (P < .01). On multivariate analysis of factors related to the rate of platelet increase with PSE, primary biliary cholangitis (B = 0.475, P < .01), splenic embolization ratio (B = 0.75, P < .01), IL-6 change ratio (B = 0.019, P < .01), and PAIgG change ratio (B = -0.325, P < .01) were significant. When attempting to improve thrombocytopenia with PSE, adequate splenic embolization needs to be obtained together with improvements in IL-6, PAIgG, and TPO levels. With unsatisfactory improvement in thrombocytopenia, TPO agonist administration was considered.

Clinical efficacy of Mac-2-binding protein glycosylation isomer as a biomarker for albumin-bilirubin grade and the Controlling Nutritional Status score in chronic liver disease: investigation of cut-off values by the type of chronic liver disease.

BACKGROUND: Mac-2-binding protein glycosylation isomer (M2BPGi), a novel noninvasive biomarker for fibrosis, is a prognostic factor for liver disease; however, its relationship with hepatic function reserve and nutritional status remains unclear. Furthermore, the cut-off value of this marker varies with the underlying liver disease. This study aims to clarify that M2BPGi can be clinically used as a hepatic function reserve marker and nutritional index without pushing the search for alternative markers to the forefront in clinical practice as an important biomarker. METHODS: Seven hundred and forty-three outpatients with chronic liver disease (CLD) were enrolled. We evaluated the relationship among M2BPGi, albumin-bilirubin (ALBI) grade, and Controlling Nutritional Status (CONUT) score as nutritional status markers. Diagnostic performance of M2BPGi values in distinguishing different modified ALBI (mALBI) grade and CONUT score were compared using receiver operating characteristic (ROC) curve analysis. RESULTS: The M2BPGi level increased with ALBI and mALBI grades. The correlation coefficient (r2) between M2BPGi and ALBI grade was 0.40 (r=0.63), indicating a positive correlation between M2BPGi and ALBI grade. The cut-off for M2BPGi to predict mALBI G1 vs. G2-G3 was 1.07, G1-2a vs. G2b-3 was 1.73, and mALBI G1-2 vs. G3 was 5.83 under the ROC curves. The cut-off for M2BPGi to predict CONUT score normal vs. light-severe was 1.60, normal-light vs. moderate-severe was 1.74, and normal-moderate vs. severe was 5.83 under the ROC curves. M2BPGi correlates with ALBI grade and is useful for diagnosing ROC analysis results, especially G2 and above. M2BPGi also correlates with the CONUT score and is useful for diagnosing ROC analysis results, especially moderate or higher. These results showed similar diagnostic performance regardless of the etiology of the background liver disease. CONCLUSIONS: Although the predictive cut-off value varied with the type of liver disease, M2BPGi was found to be a single predict biomarker of ALBI and CONUT, and thus, is an effective indicator of CLD status. Further investigation is warranted to determine the clinical utility of this marker.

Clinical Usefulness of Transjugular Liver Biopsy in Patients With Hematological Diseases With Liver Dysfunction.

Introduction Transjugular liver biopsy (TJLB) is indicated for patients in whom percutaneous liver biopsy is contraindicated, such as those with hematological diseases complicated by liver dysfunction. However, the clinical utility of TJLB in this group of patients has not been thoroughly investigated. The objective of this study is to evaluate the clinical efficacy of TJLB in patients with hematological diseases complicated by liver dysfunction. Methods We analyzed the data of patients who developed liver disorders during treatment for hematological diseases at our hospital and required tissue diagnosis via TJLB. The clinical features of patients were analyzed. Results Twenty-seven patients (mean age, 60.07 years; 12 men, 15 women) requiring tissue diagnoses via TJLB after developing liver disorders while undergoing treatment for hematological diseases were enrolled. One patient with autoimmune hemolytic anemia was diagnosed with drug-induced liver injury; two patients with amyloidosis had nonalcoholic steatohepatitis; one patient with acute promyelocytic leukemia had a drug-induced liver injury; one patient with chronic myelomonocytic leukemia had liver infiltration caused by an underlying disease; three patients with idiopathic thrombocytopenic purpura had autoimmune hepatitis; four patients with malignant lymphoma had liver infiltration by the underlying disease, and one patient with multiple myeloma had liver disorder caused by disseminated intravascular coagulation. Moreover, one patient had hepatitis B reactivation, another had hepatitis E, and six patients had a drug-induced liver injury. The treatment regimen was altered in cases of liver infiltration caused by the underlying disease, and the drug was changed for patients with drug-induced liver injury. Conclusion The etiology of liver disorders in patients with hematological diseases varies widely. Therefore, histological diagnosis using TJLB is useful to determine an appropriate therapeutic strategy for underlying hematological diseases.

Clinical Efficacy of Liver Tumor Biopsy With Radiofrequency Ablation of the Puncture Route Using a Co-access Needle.

Background/Aim: Tumor biopsy are needed frequency for accurate diagnosis. However, percutaneous liver tumor biopsy presents a risk of complications such as bleeding and tumor seeding. We investigated the feasibility of liver tumor biopsy, followed by cauterization with expandable radiofrequency ablation. Patients and Methods: Tumor biopsies using a co-access needle were performed in 102 patients. Expandable radiofrequency ablation was used to ensure cauterization and hemostasis of the puncture route. We evaluated the clinical background and complications. Results: The average (±standard deviation) tumor diameter was 56.87±39.45 mm. Pathological diagnosis was possible in all cases. In 20 patients, the postoperative pathological diagnosis differed from the preoperative diagnosis. No significant anemia progression was observed in any patients after biopsy, and no peritoneal seeding was observed during a mean follow-up observation period of 18.5 months. Conclusion: Liver tumor biopsy, followed by cauterization with expandable radiofrequency ablation via a co-access needle, is safe and useful for obtaining reliable diagnoses.
