RESUMEN
AIM: The aim of this study was to evaluate the use of a new classification for safer transradial access hepatic interventional radiology, based on preoperative evaluation of the location of the left subclavian artery bifurcation in the aortic arch. METHODS: A total of 38 consecutive patients with hepatocellular carcinoma and 74 sessions of radial access for visceral intervention (R.A.V.I.) were reviewed. We classified the location of the left subclavian artery bifurcation in the aortic arch in three areas using an oblique view computed tomography image matched with the curve of the aortic arches according to a new criteria Three Areas Criteria For R.A.V.I. (named "TAC-F-R"), and measured the required time from initial left radial artery arteriography to celiac artery or superior mesenteric artery arteriography. RESULTS: The median time required for left radial artery arteriography to the celiac artery or superior mesenteric artery arteriography in each of the three areas were: area A, 0:11:10 (h, min, s); area B, 0:14:44; and area C, 0:31:51. There were significant differences between each area after Bonferroni correction (p < 0.01; A vs. B, p = 0.086; A vs. C, p = 0.001; and B vs. C, p = 0.045), with areas A and B requiring a significantly shorter time. Finally, no patients showed neurogenic disfunction within 1 week after the R.A.V.I. CONCLUSIONS: The new classification, "TAC-F-R," for safer transradial access hepatic interventional radiology is effective for avoiding difficult cases, and selects more suitable patients with hepatocellular carcinoma for the R.A.V.I.
RESUMEN
AIMS: The effects of genetic polymorphism on a personalized diet and exercise program for steatotic liver disease (SLD) are still unclear. METHODS: Participants of this retrospective cohort study were 203 Japanese patients with SLD diagnosed by abdominal ultrasonography. All of them were introduced the personalized diet and exercise treatment. A diet of 25-30 kcal/kg multiplied by ideal body weight (BW) daily and aerobic and resistance exercise (exercise intensity of 4-5 metabolic equivalents daily, respectively) were performed for 6 days. Treatment efficacy was evaluated in terms of the rate of decrease of liver function tests, glycolipid metabolism markers, physical findings, image findings, and cardiovascular disease (CVD) risk score at 6 months compared with baseline. Furthermore, the impact of genetic polymorphism was also investigated. RESULTS: At 6 months compared with baseline, liver function tests (AST, ALT, γGTP), glycolipid metabolism markers (hemoglobin A1c, triglycerides [TG], low-density lipoprotein cholesterol), physical findings (BW, body mass index), image finding (liver stiffness measurement), and CVD risk score (Suita score) improved significantly. There was no significant difference in treatment efficacy, except for the rates of decrease of TG, according to genotype PNPLA3 rs738409, TM6SF2 rs58542926, and HSD17B13 rs6834314. The rates of decrease of TG with TM6SF2 CT were significantly higher than those with CC or TT, and the rates of TG with HSD17B13 AA were significantly higher than those with AG by multiple comparisons. CONCLUSION: Personalized diet and exercise program for SLD improved liver function tests, physical findings, glycolipid metabolism markers, and CVD risk score. Genetic polymorphism might partially affect treatment efficacy. Further studies should be performed to develop an individualized program for SLD, considering genetic polymorphism.
RESUMEN
BACKGROUND: This study investigates short-term outcomes following surgical interventions for atrial fibrillation (Af), including the Cox-maze â £ procedure (maze procedure) and pulmonary vein isolation (PVI), performed concurrently with other cardiac surgeries. Additionally, we aim to determine the indications for surgical intervention for Af. METHOD: We retrospectively studied a total of 1,580 patients, out of which 274 had preoperative Af, that underwent cardiac surgery between January 2015 and April 2023. Patients who underwent emergency surgery, died in the hospital postoperatively, or received pacemaker implantation were excluded. Patients were first divided into two groups:the intervention group (n=135, 53.6%) and the non-intervention group( n=117, 46.4%), further categorized by whether they were in sinus rhythm at discharge. The intervention group was then subdivided into the maze procedure group( n=54), and the PVI group (n=76). RESULTS: Within the maze procedure group, significant differences were observed between the sinus rhythm and non-sinus rhythm groups in terms of age, preoperative Af duration, and aortic valve intervention status. In the PVI group, patients with persistent Af, longer preoperative Af duration, and larger left atrium diameter( LAD) were less likely to return to sinus rhythm. Smaller LAD was also a significant factor for returning to sinus rhythm in the non-intervention group. Multivariate analysis for all patients revealed that an LAD smaller than 50 mm was the strongest predictor for returning to sinus rhythm post operation( p<0.01). CONCLUSION: For patients with persistent Af, the maze procedure is favored over PVI as a surgical intervention. When LAD exceeds 50 mm, the likelihood of returning to sinus rhythm is diminished.

INTRODUCTION: Simple predictive markers enabling even nonspecialized medical doctors and clinicopathological features of primary liver cancer (PLC) following HCV clearance with direct-acting antivirals (DAAs) are unclear. METHODS: The subjects of this retrospective study were 2,476 patients following HCV clearance with DAAs. All patients were confirmed to be PLC-free before and during DAAs. RESULTS: PLC was diagnosed in 73 patients during the follow-up, with an incidence rate per 1 000 person-years of 5.9. The annual rate of PLC during the first 6 years was 0.6%. Multivariate analysis identified gender, GGT, and FIB-4 index as the significant determinants of PLC. According to a combination of these risk factors, the cumulative PLC incidence rates were significantly different among the five subgroups based on the number of PLC risk scores. In 73 patients with PLC, the rates of abnormal AFP, PIVKAII, and serum TERT C228T positive were 37.0, 32.4, and 22.2%. PIVKAII levels in BCLC stage A and B were significantly higher than those in stage 0. In 41 patients, who underwent surgical resection for PLC, maximum tumor diameters of abnormal PIVKAII were significantly larger than those of normal PIVKAII. PLC of abnormal PIVKAII significantly indicated presence of vp more than that of normal PIVKAII, and did not contain well-differentiated HCC. CONCLUSIONS: Combination of simple markers, enabling even nonspecialized medical doctors, is useful for the evaluation of PLC risk following HCV clearance with DAAs. However, imaging studies are regularly recommended for the early detection of PLC.

INTRODUCTION: Personalized medicine and molecular therapies with the diagnosis of somatic genetic alterations are expected to be developed for liver cancer. Nevertheless, it is unknown whether a mutation in the telomere reverse transcriptase promoter (TERT C228T) in serum cfDNA might be useful for making prognostic predictions after surgical resection for primary liver cancer. METHODS: This cohort study retrospectively investigated 111 patients who had undergone surgical resection of liver cancer for the first time. We investigated the differences between clinicopathological features and prognosis according to classification of three tumor markers, including AFP, PIVKAII, and TERT C228T. RESULTS: Multivariate analysis identified etiology (fatty liver disease vs. HBV odds ratio [OR] 6.853) and fibrosis stage (2-4, OR: 0.137) as determinants of TERT C228T-positive liver cancer with normal levels of AFP and PIVKAII (TERT single positive liver cancer). TERT single positive (Yes, OR: 0.301), fibrosis (FIB)-4 index (≥3.25, OR: 2.038), Child-Pugh classification (B, OR: 4.975), and number of tumors (≥2, OR: 4.098) were identified as determinants of the recurrence of liver cancer. TERT single positive (Yes, OR: 3.311), FIB-4 index (≥3.25, OR: 0.433), and number of tumors (≥2, OR: 0.262) were identified as determinants of disease-free survival. CONCLUSIONS: Our results highlight the impact of classification of prognostic tumor markers. TERT single positive is one predictor of favorable prognosis after surgical resection for liver cancer.
RESUMEN
INTRODUCTION: When lenvatinib is administered to people with hepatocellular carcinoma (HCC), tumor blood flow is reduced due to the inhibition of the vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR). Few studies have examined the decrease in tumor blood flow with respect to changes in tumor blood vessels (TBVs) in clinical practice. We investigated the mechanism of tumor blood flow control by investigating changes in the diameter of relatively large TBVs in large-sized lesions with high blood flow. METHODS: From January 2011 to October 2021, patients receiving lenvatinib for unresectable intrahepatic HCC at Toranomon Hospital, Tokyo, Japan, were considered for inclusion. We investigated the TBV diameter in the arterial phase of dynamic computed tomography before treatment and its change over time (2-12 weeks after lenvatinib initiation). The relationship between changes in TBV diameter and prognosis was also examined. RESULTS: Of 114 patients treated with lenvatinib for HCC, 26 patients who had intrahepatic lesions with a tumor diameter of 30 mm or more enrolled in the study. The median tumor and TBV diameters before treatment were 58 mm and 2.55 mm, respectively. Twenty-five patients (96%) had a shrinkage in TBV diameter 2-12 weeks after lenvatinib administration. The maximum TBV diameter shrinkage of 20% or more was observed in 19 patients (73%), and progression-free survival was prolonged in these patients compared to the group with less than 20% TBV diameter shrinkage (p = 0.039). DISCUSSION/CONCLUSION: Due to the antiangiogenic effect of lenvatinib, a shrinkage in the TBV diameter of HCC was observed. The shrinkage of TBV may be regarded as a process of normalization of TBVs. The shrinkage of TBVs in imaging analysis may be associated with improved prognosis; however, additional studies are still required.

AIMS: Both diet and exercise counseling are recommended for patients with fatty liver, including nonalcoholic fatty liver disease (NAFLD), to achieve weight loss goals. However, data evaluating treatment efficacy are limited. METHODS: The subjects of this retrospective cohort study were 186 consecutive Japanese cases with fatty liver diagnosed by abdominal ultrasonography. Treatment efficacy and predictive factors of "Hospitalization Program for Improvement Purpose for Fatty Liver" as a combined diet and aerobic and resistance exercise program were evaluated according to the hospitalization group (153 cases) or the no hospitalization group (33 cases). To balance the confounding biases, treatment efficacy was evaluated using propensity score-matched analysis. In the hospitalization group, a diet of 25-30 kcal/kg multiplied by ideal body weight (BW) daily and aerobic and resistance exercise (exercise intensity of 4-5 metabolic equivalents daily, respectively) were performed for 6 days. RESULTS: In liver function tests and BW at 6 months compared with baseline, the rates of decrease of the hospitalization group (24 cases) were significantly higher than those of the no hospitalization group (24 cases), using propensity score-matched analysis. In markers of glycolipid metabolism and ferritin levels, the rates of the hospitalization group were not different from those of the no hospitalization group. In the hospitalization group (153 cases), multivariate regression analysis identified the etiology of non-NAFLD, the presence of diabetes mellitus, and large waist circumference as independent predictors of decreased rates of hemoglobin A1c levels. CONCLUSION: The diet and exercise program for fatty liver improved liver function tests and BW. Further study should be performed to develop a feasible and suitable program.
RESUMEN
Acute hepatitis E, one of the causes of acute liver injury, has been increasingly diagnosed in developed countries in recent years. Misdiagnosis of acute hepatitis E virus (HEV) infection as drug-induced liver injury (DILI) may lead to discontinuation of effective chemotherapy. Thus, viral hepatitis, including hepatitis E, must be ruled out in the diagnosis of DILI. A 78-year-old woman with lung adenocarcinoma and multiple bone metastases received maintenance therapy with pemetrexed + pembrolizumab for a year. Increased aspartate aminotransferase and alanine aminotransferase levels, indicating acute liver injury, were observed. Initially, DILI was suspected, and she was given medications to lower the levels of hepatic enzymes. She was later admitted to the hospital with the chief complaint of general malaise and anorexia. Serum aspartate aminotransferase and alanine aminotransferase levels were markedly elevated (381 and 854 U/L, respectively). Acute HEV infection was diagnosed based on the detection of serum HEV immunoglobulin A antibodies. The patient received liver support therapy, and the serum hepatic enzymes recovered to normal levels. Chemotherapy was resumed without any subsequent relapse of hepatic enzyme elevation. When DILI is suspected during chemotherapy, exclusion of viral hepatitis is mandatory, which can be achieved by measuring markers of hepatitis viruses, including HEV, and examining the patient's detailed medical history.

Cases that are inoperable owing to poor preoperative conditions are sometimes encountered. However, there are some cases that are led to radical treatment by performing bridge therapy. Here, we presented a case of a patient with complex cardiac disease in an inoperable state who underwent bridging therapy that led to successful surgical treatment. A 73-year-old male who received hemodialysis treatment and had severe aortic valve stenosis and coronary artery disease planned surgical treatment. However, he was deemed inoperable owing to his low cardiac function and hemodynamic instability. Therefore, to escape from a fatal condition, we first performed balloon aortic valvuloplasty and percutaneous coronary intervention as palliative procedures. Subsequently, his cardiac function and hemodynamic stability remarkably improved; therefore, after 1 month, we performed a successful radical surgical treatment. Even in inoperable patients, bridging therapy leading to radical treatment is possible.

Low cardiac output syndrome (LOS) is a condition that causes low perfusion and perfusion failure of the entire body's tissues due to a decline in heart contractile strength, posing a significant challenge in cardiothoracic surgical perioperative management. Appropriate myocardial protection is crucial to prevent ischemia-reperfusion injury during open-heart surgery and prevent LOS. The integrated myocardial protection method, proposed by Buckberg et al., is one technique employed for this purpose. In the treatment of LOS, interventions are made in the parameters of stroke volume and heart rate, structural abnormalities are excluded and dealt with, and mechanical assistance is utilized when necessary. With the aging and increasing severity of surgical patients, the risk of postoperative LOS is on the rise. Therefore, the application of appropriate myocardial protection and treatment methods leads to improved prognosis. It's worth noting that ensuring optimal myocardial protection during surgery and the correct application of medication and devices for intervention can significantly improve patient outcomes. With the rise in high-risk surgical cases due to aging and an increase in severe conditions, the importance of these interventions cannot be overstated.

BACKGROUND & AIMS: Bepirovirsen, an antisense oligonucleotide targeting pregenomic and mRNA transcripts of HBV, has been conjugated to N-acetyl galactosamine (GSK3389404) to enhance hepatocyte delivery. This dose-finding study was the first to assess GSK3389404 for chronic HBV infection. METHODS: This phase IIa, randomised, double-blind, placebo-controlled, 2-part study was conducted in 22 centres in Asia (NCT03020745). Pharmacokinetic findings from Part 1 informed Part 2 dosing. In Part 2, patients with chronic hepatitis B on nucleos(t)ide analogue therapy were randomised 11:2 to GSK3389404 (30, 60, 120 mg weekly or 120 mg bi-weekly) or placebo until Day 85. Coprimary endpoints included HBsAg response (≥1.5 log10 IU/ml reduction from baseline) rate, safety and pharmacokinetics. RESULTS: Parts 1 and 2 included 12 (9 GSK3389404, 3 placebo) and 66 patients (56 GSK3389404, 10 placebo), respectively. In Part 2, one patient each in the 60 mg weekly, 120 mg weekly and 120 mg bi-weekly arms achieved a HBsAg response. HBsAg reductions were dose-dependent (Day 85: mean 0.34 [60 mg weekly] to 0.75 log10 IU/ml [120 mg weekly]) and occurred in hepatitis B e antigen-positive and -negative patients. No patient achieved HBsAg seroclearance. 43/56 (77%) GSK3389404- and 9/10 (90%) placebo-treated patients reported adverse events. No deaths were reported. Alanine aminotransferase flares (>2x upper limit of normal) occurred in 2 GSK3389404-treated patients (120 mg weekly, 120 mg bi-weekly); both were associated with decreased HBsAg, but neither was considered a responder. GSK3389404 plasma concentrations peaked 2-4 hours post dose; mean plasma half-life was 3-5 hours. CONCLUSIONS: GSK3389404 showed an acceptable safety profile and target engagement, with dose-dependent reductions in HBsAg. However, no efficacious dosing regimen was identified. CLINICAL TRIAL NUMBER: NCT03020745. LAY SUMMARY: Hepatitis B virus (HBV) can result in chronic HBV infection, which may ultimately lead to chronic liver disease, primary liver cancer and death; HBV proteins may prevent the immune system from successfully controlling the virus. GSK3389404 is an investigational agent that targets HBV RNA, resulting in reduced viral protein production. This study assessed the safety of GSK3389404 and its ability to reduce the viral proteins in patients with chronic HBV infection. GSK3389404 showed dose-dependent reduction in hepatitis B surface antigen, with an acceptable safety profile. While no clear optimal dose was identified, the findings from this study may help in the development of improved treatment options for patients with chronic HBV infections.

INTRODUCTION: Many patients with chronic hepatitis B (CHB) are classified as indeterminate patients because they fall outside the defined CHB phases. We aimed to explore hepatocellular carcinoma (HCC) risk in hepatitis B e antigen (HBeAg)-negative patients with indeterminate phase and investigated whether the risk could be stratified by serum levels of hepatitis B core-related antigen (HBcrAg). METHODS: Two retrospective cohorts enrolling HBeAg-negative, treatment-naïve CHB patients without cirrhosis were constructed (N = 2,150 in Taiwanese discovery cohort and N = 1,312 in Japanese validation cohort with a mean follow-up period of 15.88 and 12.07 years, respectively). The primary end point was HCC development. RESULTS: According to the American Association for the Study of Liver Disease guidelines, 990 (46%) HBeAg-negative patients had indeterminate CHB phase at baseline in the Taiwanese cohort. Compared with the patients with inactive CHB and those with immune-active CHB, the indeterminate patients exhibited intermediate but diverse risk of HCC. When HCC risk was stratified by a HBcrAg level of 10,000 U/mL, 10-year HCC cumulative incidence was 0.51% and 5.33% for low HBcrAg and high HBcrAg groups, respectively, with a hazard ratio of 4.47 (95% confidence interval: 2.62-7.63). This cutoff was validated to stratify HCC risk not only in different subgroup analyses but also in an independent Japanese cohort. Finally, the overall HBeAg-negative CHB patients could be simply reclassified into high-risk and low-risk groups by combining ALT, hepatitis B virus DNA, and HBcrAg levels in both cohorts. DISCUSSION: Serum HBcrAg level of 10,000 U/mL stratifies HCC risk in HBeAg-negative patients with indeterminate phase, which is useful for optimizing their clinical management.

INTRODUCTION: It is unclear whether the relationships between changes in fibrosis and circulating microRNA-122 (miR-122) dynamics might influence the prognosis of nonalcoholic fatty liver disease (NAFLD). METHODS: This study investigates the impact of serum miR-122 dynamics and histological changes on the incidence of liver cancer and mortality in 81 Japanese NAFLD patients who underwent serial liver biopsies. The median interval between the first and second liver biopsies was 2.9 years. RESULTS: The fibrosis stage scores indicated progression, no change, and improvement (a decrease of one point or more) in 21.0%, 56.8%, and 22.2% of the patients, respectively. There were 64 patients in the high-risk group who had no improvement in stage scores. Among these, the miR-122 levels were significantly lower in 7 patients with liver cancer than those of the 54 patients who had no liver cancer at the second liver biopsy. The cumulative rates of liver cancer were significantly higher in cases with miR-122 ratios <0.5 (serum miR-122 level at second biopsy to that at first biopsy) than those with ratios ≥0.5. The cumulative survival rates in cases with miR-122 ratios <0.5 tended to be lower than those with ratios ≥0.5. Of the 64 high-risk patients, 39 indicated stage 2 or greater (severe fibrosis stage) at the first liver biopsy and also showed similar results of cumulative liver cancer and survival rates. CONCLUSIONS: Longitudinal examination of serial liver biopsies indicated that the circulating miR-122 dynamics might be useful in predicting the prognosis for NAFLD patients with severe fibrosis stage and no improvement of the stage scores.

BACKGROUND AND AIMS: The aim of this study was to identify the utility of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) as a predictor of early progressive disease (e-PD) in patients with hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab (Atezo/Bev). METHODS: Twenty consecutive patients with measurable intrahepatic target nodules who received Atezo/Bev treatment were reviewed. The oncological aggressiveness of tumors estimated by 18F-FDG-PET/CT was analyzed using the rate of e-PD within 12 weeks and early progression-free survival (e-PFS) and overall survival (OS). Multivariate analysis was used to identify potential confounders for PD during Atezo/Bev therapy. RESULTS: Using the Response Evaluation Criteria in Solid Tumors version 1.1, a tumor-to-normal liver ratio (TLR) ≥2, indicating higher oncological aggressiveness in HCCs, was associated with lower objective response rates compared with TLR values <2 (18% vs. 33%, respectively). Moreover, TLR values ≥2 were significantly associated with higher e-PD rates compared with TLR values <2 (64% vs. 11%, respectively) and worse e-PFS (p = 0.021). In multivariate analysis, TLR ≥2 showed marginal significance as a predictor of e-PD (p = 0.053), and utility as a predictor for worse e-PFS (hazard ratio, 7.153; 95% confidence interval, 1.258-40.689; p = 0.027). In contrast, no significant differences in OS with/without e-PD were observed during the treatment course. In this study, 8 patients experienced e-PD and almost 40% of patients experienced acceptable disease control following subsequent lenvatinib treatment. CONCLUSION: Pretreatment 18F-FDG-PET/CT may be a useful new predictor of e-PD and may enable early decision-making based on early treatment changes following Atezo/Bev treatment of HCC.

BACKGROUND: Long-term use of nucleotide analogs such as adefovir (ADV) or tenofovir disoproxil fumarate (TDF) may cause renal impairment. Tenofovir alafenamide (TAF) has less systemic exposure than TDF did. The aims were to examine longitudinal changes in renal function and biochemical parameters for 2 years after switching from long-term ADV and TDF to TAF, and to explore factors associated with improved renal function after TAF in patients with chronic hepatitis B. METHODS: The prospective observational cohort study included 306 patients with chronic hepatitis B who underwent switching from long-term TDF or ADV to TAF. The primary outcome was the changes in estimated glomerular filtration rate (eGFR) after TAF. RESULTS: Among 306 patients, 190 (65.3%) and 106 (34.7%) had chronic kidney disease (CKD) stages 1-2 and 3a-4 at baseline. In patients with CKD stages 3a-4, the mean eGFR significantly increased until week 12 and plateaued from week 12 to year 2 (adjusted slope using linear mixed effect models: +9.01 ml/min/1.73 m2 /year until week 12; p < 0.001). In contrast, the mean eGFR plateaued from baseline to year 2 in the CKD stages 1-2 subgroup. Multivariate logistic regression showed that baseline CKD stage ≥3a, steeper decline in eGFR 1 year before TAF, and shorter duration of any nucleotide analog use was significantly associated with ≥10% improvement in eGFR in year 1. CONCLUSIONS: Switching from TDF or ADV to TAF resulted in favorable renal safety for 2 years. In CKD stage 3a-4 subgroup, eGFR after TAF was recovered in the first 12 weeks and subsequently stabilized.
RESUMEN
BACKGROUND & PURPOSE: Protease-free regimens for chronic hepatitis C virus (HCV) infection are safe and effective for persons with either compensated or decompensated cirrhosis. We examined the efficacy and safety of sofosbuvir-velpatasvir in participants with HCV and compensated cirrhosis in Japan. METHODS: This was a Phase 3, multi-center, open-label study. At 20 sites, 37 individuals with chronic HCV infection of any genotype and compensated cirrhosis received sofosbuvir-velpatasvir (400 mg/100 mg) daily for 12 weeks. Participants were treatment-naïve or treatment-experienced with interferon-based treatments with or without HCV NS3/4A protease inhibitors. Prior exposure with HCV NS5A or NS5B inhibitors was prohibited. The primary study endpoint was sustained virologic response 12 weeks after treatment (SVR12). RESULTS: Among participants, 62% had HCV genotype 1 infection, and 38% had HCV genotype 2. More than three quarters (29/37, 78%) were HCV treatment naïve. All participants (37/37, 100%) achieved SVR12. Seventeen participants (46%) and three participants (8%) had pretreatment resistance-associated substitutions to HCV NS5A and NS5B nucleoside inhibitors respectively, yet no on-treatment breakthrough or relapse occurred. Sofosbuvir-velpatasvir for 12 weeks treatment was safe and well tolerated. The most commonly reported adverse events were headache (8%, 3/37) and diarrhea (5%, 2/37). One serious adverse event, patella fracture, occurred and was considered not treatment related. No participants discontinued study treatment due to an adverse event. Three participants (8%) had a Grade 3 laboratory abnormality; all were hyperglycemia. CONCLUSION: Sofosbuvir-velpatasvir resulted in high SVR rates and was well tolerated among Japanese patients with HCV and compensated cirrhosis. This single-tablet regimen offers a highly effective, protease-inhibitor free regimen for treating HCV. CLINICALTRIALS: gov Identifier: NCT04112303.
RESUMEN
An 81-year-old woman lost consciousness and was taken to our hospital 3 days after colonoscopy was performed as a follow-up of endoscopic mucosal resection done 1 year ago for early sigmoid colon cancer detection. She had left hypochondrial pain. Based on abdominal contrast-enhanced computed tomography (CT) findings, she was diagnosed with abdominal bleeding due to injury to the lower splenic pole, and an urgent splenectomy was performed. In this case, there was no abdominal trauma to cause splenic injury. Injury to the lower splenic pole during colonoscopy was considered due to the adhesion found in the abdominal cavity. It is possible that the hemorrhage did not stop because she was taking antiplatelet drugs.

INTRODUCTION: It remains unclear whether TERT promoter mutation (TERT C228T) in serum cell-free DNA (cfDNA) is useful for the diagnosis of hepatocellular carcinoma (HCC) in patients with nonalcoholic fatty liver disease (NAFLD). METHODS: In this retrospective study, we analyzed the relationships between TERT C228T in serum cfDNA and levels of AFP and PIVKAII in 57 Japanese patients with histopathologically confirmed NAFLD background, consisting of 36 patients with HCC and 21 without HCC. We also examined the liver-related survival rate and HCC recurrence rate after the initial treatment for HCC. TERT C228T was detected using a highly sensitive method based on wild-type blocking PCR (detection limit in excess of 0.7% mutant-type DNA). RESULTS: In all of the 57 patients, multivariate analysis identified TERT C228T positive as significant determinant of primary HCC. In the 36 patients with HCC, the percentage of patients positive for TERT C228T was 63.9%. The percentage of patients positive for TERT C228T with normal AFP and PIVKAII was 35.3%. The positive predictive value and specificity for prediction of BCLC stage 0 or A were both high. In 6 patients, TERT C228T was repeatedly negative during follow-up but became positive at the time of HCC diagnosis. Four patients who underwent HCC surgical resection had well-differentiated solitary HCC measuring <30 mm, and all were TERT C228T positive with normal AFP and PIVKAII. TERT C228T status had no influence on the cumulative liver-related survival rate and HCC recurrence rate. CONCLUSIONS: Our results highlight the superiority of TERT C228T in serum cfDNA compared with AFP and PIVKAII in the early diagnosis of primary HCC in NAFLD patients.

BACKGROUND AND AIM: The aim of this study was to identify the utility of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) as a predictor of overall prognosis in patients with hepatocellular carcinoma treated with lenvatinib. METHODS: Forty-eight consecutive patients who received lenvatinib treatment were reviewed. The oncological aggressiveness of tumors estimated using 18F-FDG-PET/CT was investigated by the analysis of progression-free survival (PFS), post-progression survival (PPS), and overall survival (OS). Multivariate analysis was used to identify potential confounders for OS during lenvatinib therapy. RESULTS: Using the Modified Response Evaluation Criteria in Solid Tumors, a tumor-to-normal liver ratio (TLR) ≥2, indicating higher oncological aggressiveness in HCCs, was associated with a better objective response to lenvatinib than a TLR <2 (78 vs. 62%), resulting in a similar PFS (p = 0.751). Because of a significantly worse PPS, OS with a TLR ≥2 was poor compared to a TLR < 2 (p = 0.012). Multivariate analysis confirmed that a TLR ≥ 2 was associated with poor OS (hazard ratio, 2.709; 95% CI, 1.140-6.436; p = 0.024). Analysis of 24 patients who received a repeat 18F-FDG-PET/CT showed that daily changes expressed as ΔTLR × 103/day over the treatment course tended to be different among the types of subsequent treatment. A R0 resection and lenvatinib-TACE sequential therapy provided good disease control (median, -4.593 and -0.024, respectively) compared with other treatments (median, 5.278) (p = 0.075). CONCLUSION: Lenvatinib has acceptable disease control regardless of estimated tumor differentiation. A high TLR (≥2) is a poor prognostic factor of OS following lenvatinib treatment, while ΔTLR × 103/day provides useful information of disease control status.

BACKGROUND: The sensitivity of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in hepatocellular carcinoma (HCC) is low; however, clinical evidence demonstrating its prognostic value in patients with HCC has recently been reported. This study aimed to assess the value of 18F-FDG-PET/CT as a tool for evaluating the response of HCC to lenvatinib treatment. METHODS: We evaluated 11 consecutive patients with HCC diagnosed by dynamic CT or magnetic resonance imaging combined with 18F-FDG-PET/CT from April 2018 to December 2019. The tumor-to-normal liver ratio (TLR) of the target tumor was measured before and during the course of lenvatinib treatment with 18F-FDG-PET/CT (pre and post analysis, respectively), with a TLR ≥2 classified as PET-positive HCC. At the time of each evaluation, we also used the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, the modified RECIST (mRECIST), and the tumor marker alfa-fetoprotein (AFP). RESULTS: Of 11 patients, 3 (27%) and 8 (73%) had an objective response to lenvatinib treatment at the time of post-analysis by RECIST 1.1 and mRECIST, respectively. There were 3 (27%) and 7 (64%) patients with PET-positive HCC at the time of pre- and post-analysis, respectively. There was a significant correlation between the rates of change in AFP and TLR during lenvatinib treatment (r = 0.69, p = 0.019). Based on these results, we were able to perform liver resection on 4 patients with PET-positive HCC as conversion therapy. Three samples from these patients showed poorly differentiated tumors. CONCLUSION: 18F-FDG-PET/CT has potential as an evaluation tool for describing biological tumor behavior and reflecting disease progression, location, and treatment response. This modality may provide useful information for considering prognosis and subsequent therapy.
