RESUMO

BACKGROUND AND AIMS: Glycogen storage disease type I (GSD-I) is an autosomal recessive disorder of carbohydrate metabolism, resulting in limited production of glucose and excessive glycogen storage in the liver and kidneys. These patients are characterized by life-threatening hypoglycemia, metabolic derangements, hepatomegaly, chronic kidney disease, and failure to thrive. Liver transplantation (LT) has been performed for poor metabolic control and delayed growth. However, renal outcome was diverse in pediatric GSD patients after LT. The aim of this study was to investigate the long-term outcome of renal function in pediatric GSD-I patients after living donor LT (LDLT), and to identify modifiable variables that potentially permits LT to confer native renal preservation. METHODS: The study included eight GSD-Ia and one GSD-Ib children with a median age of 9.0 (range 4.2-15.7) years at the time of LT. Using propensity score matching, 20 children with biliary atresia (BA) receiving LT were selected as the control group by matching for age, sex, pre-operative serum creatinine (SCr) and pediatric end-stage liver disease (PELD) score. Renal function was evaluated based on the SCr, estimated glomerular filtration rate (eGFR), microalbuminuria, and morphological changes in the kidneys. Comparability in long-term renal outcome in terms of anatomic and functional parameters will help to identify pre-LT factors of GSD-I that affect renal prognosis. RESULTS: The clinical and biochemical characteristics of the GSD and BA groups were similar, including immunosuppressive regimens and duration of follow-up (median 15 years) after LT. Overall, renal function, including eGFR and microalbuminuria was comparable in the GSD-I and BA groups (median eGFR: 111 vs. 123 ml/min/1.73m2, P = 0.268; median urine microalbuminuria to creatinine ratio: 16.0 vs. 7.2 mg/g, P = 0.099, respectively) after LT. However, in the subgroups of the GSD cohort, patients starting cornstarch therapy at an older age (≥ 6-year-old) before transplantation demonstrated a worse renal outcome in terms of eGFR change over years (P < 0.001). In addition, the enlarged kidney in GSD-I returned to within normal range after LT. CONCLUSIONS: Post-LT renal function was well-preserved in most GSD-I patients. Early initiation of cornstarch therapy before preschool age, followed by LT, achieved a good renal prognosis.

RESUMO

Tumor recurrence is the most common cause of death in hepatocellular carcinoma (HCC) patients who received liver transplantation (LT). Recently, lenvatinib was approved for the systemic treatment of unresectable HCC patients; however, the role of lenvatinib in HCC patients after LT remains unclear. There were 56 patients with recurrent HCC after LT from 2008 to 2018 in our institute, and 10 patients who received lenvatinib were identified. Additionally, to understand the difference in the clinical impact of lenvatinib in the LT and non-LT settings, 25 HCC patients without LT who underwent lenvatinib treatment were identified from our HCC database and regarded as the control group. In the LT group, partial response was 20% and stable disease was 50%, resulting in a disease control rate of 70%; the median progression-free survival (PFS), time to treatment failure (TTF) and overall survival (OS) were 3.7, 3.6 and 16.4 months, respectively. Adverse events (AEs) were predominantly grade 1-2 in severity, and the majority of patients tolerated the side effects. There was no significant difference in PFS/OS, and we observed a similar pattern of AEs between these two groups. Our study confirms the comparable efficacy and safety of lenvatinib in HCC patients with LT and non-LT in clinical practice.

RESUMO

Despite technological and immunological innovations, living-donor liver transplant (LDLT) recipients still face substantial risk of postoperative complications. Sarcopenia is being recognized more and more as a biomarker that correlates with poor outcomes in surgical patients. The purpose of this study was to evaluate the relationship between sarcopenia and significant surgical complications in LDLT recipients. This retrospective review included patients who had received LDLT at our institute from 2005 to 2017. Sarcopenia was assessed using the psoas muscle index (PMI) in cross-sectional images. ROC curve analysis was used to determine the ability of PMI to predict postoperative complications. Correlations between major postoperative complications and sarcopenia were evaluated using regression analysis. A total of 271 LDLT recipients were included. No significant differences were found between PMI and major postoperative complications in male patients. Female recipients with major postoperative complications had significantly lower mean PMI values (P = 0.028), and the PMI cut-off value was 2.63 cm2/m2. Postoperative massive pleural effusion requiring pigtail drainage occurred more frequently in the sarcopenia group than in the non-sarcopenia group (P = 0.003). 1-, 3-, 5- and 10-year overall survival rates in female were significantly poorer in the sarcopenia group (n = 14) compared with the non-sarcopenia group (n = 108), at 92.9% versus 97.2%, 85.7% versus 95.4%, 85.7% versus 92.5% and 70.1 versus 82.0%, respectively (P = 0.041) and 94.6%, 89.9%, 85.9% and 78.5% in male patients. Sarcopenia is associated with a significantly higher risk of major postoperative complications in females. PMI and sarcopenia together are predictive of major postoperative complications and survival rates in female LDLT recipients.

RESUMO

BACKGROUNDS AND AIM: Metabolic-associated fatty liver dis-ease (MAFLD) is a novel term proposed in 2020 to avoid the exclusion of certain subpopulations, though the application of this term in the real world is very limited. Here, we aimed to evaluate the impact of MAFLD on hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after curative resection. METHODS: Patients with chronic hepatitis B (CHB)-related HCC who received hepatectomy between January 2010 and December 2019 were consecutively selected. The association between histologically proven concurrent MAFLD and clinical outcomes were retrospectively analyzed. RESULTS: Among the 812 eligible patients with CHB-related HCC, 369 (45.4%) were diagnosed with concurrent MAFLD. After a mean follow-up of 65 months, 303 patients (37.3%) developed HCC recurrence, 111 (13.7%) died, and 12 (1.5%) received liver transplantation. Although no differences in the incidences of HCC recurrence (HR: 0.902, 95% CI: 0.719-1.131, p = 0.370) and death or liver transplantation (HR: 0.743, 95% CI: 0.518-1.006, p = 0.107) were observed between patients with and without MAFLD in multivariate analysis, the patients with MAFLD tended to achieve better recurrent-free survival compared to patients without MAFLD. Notably, lean MAFLD (BMI < 23 kg/m2) was a relative risk factor for tumor recurrence (HR: 2.030, 95% CI: 1.117-3.690, p = 0.020) among patients with MAFLD. CONCLUSIONS: The overall prognosis in HBV-related early-stage HCC, in terms of HCC recurrence and death or liver transplantation, was not significantly different between patients with and without MAFLD. Among patients with MALFD, lean-MAFLD was a risk factor for HCC recurrence. Further studies are warranted to validate these results.

RESUMO

To validate a previously reported alpha-fetoprotein (AFP) model (including three variables: preoperative image-diagnosed tumor number and size and AFP level) for the prediction of recurrence in hepatocellular carcinoma (HCC) patients who have undergone liver resection (LR). This retrospective study enrolled patients who underwent curative LR for newly diagnosed HCC in our institution between 2011 and 2018. The probabilities of overall survival (OS) and recurrence were compared according to the aforementioned AFP model. A total of 838 patients were included. AFP score ≥ 3 versus ≤ 2 independently predicted recurrence and OS. However, net reclassification improvements (NRI) indicated that the AFP model was not superior to the Barcelona Clinic Liver Cancer (BCLC) system for predicting 1-year recurrence (p = 0.746). Relatedly, we developed a modified AFP model based on our cohort. The modified AFP score ≥ 3 versus ≤ 2 independently predicted recurrence and OS. However, NRI again indicated that the modified AFP model was not superior to the BCLC system for predicting 1-year recurrence (p = 0.69). Patients with a modified AFP score ≤ 2 had a risk of recurrence similar to that of patients with a modified AFP score ≥ 3 in BCLC stage 0-A (p = 0.57). However, patients with a modified AFP score ≤ 2 had a lower risk of recurrence than patients with a modified AFP score ≥ 3 in BCLC stage B-C (p = 0.02). The original AFP model was not feasible in our cohort. However, the modified AFP model may be useful for predicting recurrence in BCLC B-C patients who underwent LR in our cohort.

RESUMO

OBJECTIVE: To compare hepatitis C virus (HCV) RNA levels from serum and explanted native liver samples from patients undergoing living donor liver transplantation (LDLT). METHODS: This was a prospective observational study. Serum and liver samples were collected from consecutive serum anti-HCV-positive transplant recipients between February 2016 to August 2019. HCV RNA was extracted from liver samples and subjected to one-step reverse-transcription qPCR. using the TopScript One Step qRT-PCR Probe Kit with HCV qPCR probe assay and human GAPDH qPCR probe assay on a ViiA7 Real-Time PCR System. RESULTS: Among the 80 patients, 36% (29/80) were HCV RNA positive in serum and 85% (68/80) had positive hepatic HCV RNA. Post-liver transplantation, 4% (3/80) patients were serum positive. CONCLUSIONS: Our study suggests that pre-transplant serum HCV RNA levels may give an underestimate of the number of positive HCV RNA cases and that hepatic HCV RNA data may be more accurate.

RESUMO

BACKGROUND: To assess preoperative image tumor characteristics and alpha-fetoprotein (AFP) levels to predict early recurrence after liver resection (LR) for hepatocellular carcinoma (HCC). METHODS: This retrospective study's enrolled patients underwent LR for newly diagnosed HCC between 2011 and 2018. Multivariate logistic regression analyses using the Akaike information criterion were adopted to construct a nomogram to predict early recurrence (i.e. recurrence within 1 year). The performance of this nomogram was evaluated using calibration plots with bootstrapping. RESULTS: Early recurrence was identified in 99 patients (11.2%). Four predictive factors, namely an AFP level of >400 ng/mL; image-diagnosed tumor characteristics, including a tumor size of > 5 cm; vascular invasion; and multiple tumors were adopted in the final model of the early recurrence nomogram, with a concordance index of 0.67. The calibration plots showed good agreement between the nomogram predictions and the actual observations of early recurrence. CONCLUSION: We have developed a simple nomogram with preoperative image tumor characteristics and AFP levels to predict the early recurrence of HCC after LR.

RESUMO

BACKGROUND With the introduction of rituximab, ABO-incompatible (ABOi) living donor liver transplantation (LDLT) has been considered a feasible and safe procedure to overcome the shortage of organ donors. However, higher biliary complication rates remain an unresolved problem in the ABOi group. In our center, biliary anastomosis has been done with microscopic biliary reconstruction (MBR), which effectively reduced the biliary complication rate. The aim of the current study was to investigate whether the microscopic approach reduced anastomotic biliary complications in ABOi LDLT. MATERIAL AND METHODS From March 2006 to December 2018, 30 adult ABOi and 60 ABO-compatible (ABOc) LDLT patients were selected from over 1300 recipients through 1: 2 propensity score-matched cohorts. All patients received MBR during the transplantation. Biliary complications included bile leakage and biliary stricture. Patients with diffuse intrahepatic biliary stricture were excluded from analysis. RESULTS Patient characteristics were similar in the 2 groups. There was no in-hospital mortality in the ABOi LDLT. The long-term survival rates of the ABOi patients were comparable to those of the patients that underwent ABOc LDLT (87.1% vs 87.4%, P=0.964). Those in the ABOi group with anastomotic biliary complications were about 40%, which was higher than in the ABOc patients (40% vs 15%, P=0.01). CONCLUSIONS Microscopic biliary reconstruction does not help to reduce the high biliary complication rate in ABOi LDLT. Further investigation and identification regarding other risk factors and precautionary measures involving immunologic and adaptation mechanisms are needed.

RESUMO

Importance: Living-donor liver transplant (LDLT) offers advantages over deceased-donor liver transplant (DDLT) of improved intention-to-treat outcomes and management of the shortage of deceased-donor allografts. However, conflicting data still exist on the outcomes of LDLT in patients with hepatocellular carcinoma (HCC). Objective: To investigate the potential survival benefit of an LDLT in patients with HCC from the time of waiting list inscription. Design, Setting, and Participants: This multicenter cohort study with an intention-to-treat design analyzed the data of patients aged 18 years or older who had an HCC diagnosis and were on a waiting list for a first transplant. Patients from 12 collaborative centers in Europe, Asia, and the US who were on a transplant waiting list between January 1, 2000, and December 31, 2017, composed the international cohort. The Toronto cohort comprised patients from 1 transplant center in Toronto, Ontario, Canada who were on a waiting list between January 1, 2000, and December 31, 2015. The international cohort centers performed either an LDLT or a DDLT, whereas the Toronto cohort center was selected for its capability to perform both LDLT and DDLT. The benefit of LDLT was tested in the 2 cohorts before and after undergoing an inverse probability of treatment weighting (IPTW) analysis. Data were analyzed from February 1 to May 31, 2020. Main Outcomes and Measures: Intention-to-treat death was defined as a patient death that occurred for any reason and was calculated from the time of waiting list inscription for liver transplant to the last follow-up date (December 31, 2019). Four multivariable Cox proportional hazards regression models for intention-to-treat death were created. Results: A total of 3052 patients were analyzed in the international cohort, of whom 2447 were men (80.2%) and the median (IQR) age at first referral was 58 (53-63) years. The Toronto cohort comprised 906 patients, of whom 743 were men (82.0%) and the median (IQR) age at first referral was 59 (53-63) years. In all the settings, LDLT was an independent protective factor, reducing the risk of overall death by 49% in the pre-IPTW analysis for the international cohort (HR, 0.51; 95% CI, 0.36-0.71; P < .001), 33% in the post-IPTW analysis for the international cohort (HR, 0.67; 95% CI, 0.53-0.85; P = .001), 43% in the pre-IPTW analysis for the Toronto cohort (HR, 0.57; 95% CI, 0.45-0.73; P < .001), and 48% in the post-IPTW analysis for the Toronto cohort (HR, 0.52; 95% CI, 0.42 to 0.65; P < .001). The discriminatory ability of the mathematical models further improved in all of the cases in which LDLT was incorporated. Conclusions and Relevance: This study suggests that having a potential live donor could decrease the intention-to-treat risk of death in patients with HCC who are on a waiting list for a liver transplant. This benefit is associated with the elimination of the dropout risk and has been reported in centers in which both LDLT and DDLT options are equally available.

RESUMO

Background and Objectives: Protease activated receptor-2 (PAR2) is elevated in a variety of cancers and has been promoted as a potential therapeutic target. However, the clinical and prognostic values of PAR2 in hepatocellular carcinoma (HCC) are poorly characterized. This study aimed to evaluate the expression of PAR2 in HCC tissues and examine the prognostic value of PAR2 after resection in HCC. Materials and Methods: Two hundred and eight resected specimens were collected from HCC patients at Kaohsiung Chang Gung Memorial Hospital. PAR2 protein expression was assessed by western blotting in HCC tissues and matched normal tissues. The correlation between PAR2 expression and clinicopathological parameters was analyzed. Disease-free survival (DFS) and overall survival (OS) were compared using the log-rank test. A Cox regression model was used to identify independent prognostic factors. Results: PAR2 was expressed at higher levels in HCC tissues than the paired adjacent nontumor tissues. High expression of PAR2 was associated with advanced tumor, node, metastasis (TNM )stage and histological grade. Kaplan-Meier analysis indicated high PAR2 expression was associated with poorer DFS and OS compared to low PAR2 expression. Multivariate analyses indicated high PAR2 expression [hazard ratio (HR), 1.779, p = 0.006), α-fetoprotein (AFP) (HR, 1.696, p = 0.003), liver cirrhosis (HR, 1.735, p = 0.002), and advanced TNM stage (HR, 2.061, p < 0.001) were prognostic factors for DFS, and advanced TNM stage (HR, 2.741, p < 0.001) and histological grade (HR, 2.675, p = 0.002) and high PAR2 expression (HR, 1.832, p = 0.012) were significant risk factors for OS. In subgroup analyses, the combination of PAR2 expression and serum AFP provided improved prognostic ability for OS and DFS. Conclusion: Combination PAR2 and AFP predict HCC outcomes after resection. PAR2 represents a potentially clinically relevant biomarker for HCC.

RESUMO

Acute-on-chronic liver failure (ACLF) is a fatal condition, and liver transplantation (LT) is a vital option for these patients. However, the result of living donor LT (LDLT) for ACLF is not well investigated. This study investigated the outcomes of LDLT in patients with ACLF compared with patients without ACLF. This was a single-center, retrospective, matched case-control study. From July 2002 to March 2017, a total of 112 patients with ACLF who underwent LDLT were enrolled according to the consensus of the Asian Pacific Association for the Study of the Liver. A total of 224 patients were selected for control comparison (non-ACLF) with demographic factors (sex, age, and body mass index) matched (1:2). Patients with ACLF were stratified into ACLF 1, 2, and 3 categories according to the number of organ failures based on the Chronic Liver Failure-Sequential Organ Failure Assessment score. Survival and surgical outcomes after LDLT were analyzed. The Model for End-Stage Liver Disease and Child-Turcotte-Pugh scores in the ACLF group were significantly higher than those in the non-ACLF group (P < 0.001). The 90-day, 3-year, and 5-year survival rates in the ACLF and non-ACLF groups were 97.3%, 95.5%, 92.9%, respectively, and 96.9%, 94.2%, and 91.1%, respectively (P = 0.58). There was more intraoperative blood loss in the ACLF group than in the non-ACLF group (P < 0.001). The other postoperative complications were not significantly different between the groups. A total of 20 patients (17.9%) in the ACLF group presented with 3 or more organ system dysfunctions (ACLF 3), and the 90-day, 3-year, and 5-year survival rates were comparable with those of ACLF 1 and ACLF 2 (P = 0.25). In carefully selected patients, LDLT gives excellent outcomes in patients with ACLF regardless of the number of organs involved. Comprehensive perioperative care and timely transplantation play crucial roles in saving the lives of patients with ACLF.

RESUMO

BACKGROUND: Large well-differentiated hepatocellular carcinoma (HCC) ≥ 3 cm (defined as atypical HCC) is uncommon. We evaluated the characteristics and outcomes of atypical HCC patients underwent liver resection (LR). METHODS: This retrospective study enrolled patients who underwent LR for HCC from 2007 to 2017. Patient characteristics and overall survival (OS) were compared between patients with atypical HCC and patients with typical HCC (moderate-to-undifferentiated HCC ≥ 3 cm). RESULTS: Among 598 patients, 51 (8.5%) had atypical HCC. Patients with atypical HCC had higher rates of non-hepatitis B or C infections (p = 0.02) and American Joint Committee on Cancer T1 pathology (p < 0.001), a lower rate of alpha-fetoprotein >20 ng/ml (p < 0.001) and a longer OS (p < 0.001) than those with typical HCC. Multivariate analysis showed that atypical HCC was associated with OS (HR = 0.50, 95% CI = 0.27-0.91, p = 0.02). CONCLUSIONS: Patients with atypical HCC have a higher rate of non-hepatitis B or C infections and a lower rate of aggressive tumor biologic behavior. Atypical HCC is an independent predictor of OS.

RESUMO

Increasing proportions of elderly patients with hepatocellular carcinoma (HCC) requiring oncological treatment have been noted. We aim to evaluate the impact of elderly age on outcomes of liver resection (LR) for HCC. This retrospective study enrolled 1004 patients with HCC who underwent curative LR in our institution from 2007 to 2017, dividing them into three groups according to age (18-59 years, n = 461; 60-74 years, n = 447; ≥ 75 years, n = 96). Elderly patients were defined as those ≥ 75 years old. Outcomes were then compared among the three groups, with a multivariate competing risk model used to estimate cause-specific subdistribution hazard ratios (SHRs) for HCC- and non-HCC-related deaths. The OS was significantly lower in the elderly than younger patients. However, recurrence-free survival was similar among the three groups. The cumulative incidence of HCC-related death was similar among the three groups; however, the cumulative incidence of non-HCC-related death was significantly higher in the elderly than younger patients. Moreover, the multivariate analysis showed that elderly age was not an independent variable associated with HCC-related death. However, elderly age was an independent variable associated with non-HCC-related death. The 60-year SHR for non-HCC-related death increased with increasing age. The elderly patients had significantly worse OS after LR than the younger patients, possibly due to the cumulative incidence of non-HCC-related death being significantly higher among the elderly than among the younger patients. Elderly patients should be more stringently selected for LR.

RESUMO

BACKGROUND AND AIMS: The Barcelona Clinic Liver Cancer (BCLC) staging system is the most widely applied staging system for hepatocellular carcinoma (HCC) and is recommended for treatment allocation and prognostic prediction. The BCLC guidelines were modified in 2018 to indicate that Child-Pugh A without any ascites is essential for all stages except stage D. This study sought to provide a description of patients with HCC treated at a high-volume liver surgery center in Taiwan where referral is not needed and all treatment modalities are available and reimbursed by the National Health Insurance program. As such, certain variables that could modulate treatment decisions in clinical practice, including financial constraints, the availability of treatment procedures, and the expertise of the hospital, could be excluded. The study further sought to evaluate the adherence to the modified BCLC guidelines. METHODS: This was a retrospective study with prospectively collected data. 1801 consecutive patients with de novo HCC were enrolled through our institution from 2011-2017. RESULTS: There were 302 patients with stage 0, 783 with stage A, 242 with stage B, 358 with stage C, and 116 with stage D HCC. Treatment adhering to the modified BCLC guidelines recommendations was provided to 259 (85.8%) stage 0 patients, 606 (77.4%) stage A patients, 120 (49.6%) stage B patients, 93 (26.0%) stage C patients, and 83 (71.6%) stage D patients. CONCLUSIONS: We reported treatment adhering to the modified BCLC guidelines at a high-volume liver surgery center in Taiwan. We found that non-adherence to the modified BCLC staging system was common in treating stage B and C patients.

RESUMO

Background: Liver transplantation (LT) is one of the widely recognised and leading treatments for end-stage liver disease. Nutrition impacts its success. Total parenteral nutrition (TPN) is usually prescribed for patients recommended prolonged fasting after LT. The supplement of SMOFlipid (soybean oil, MCT oil, olive oil, and fish oil) is easily metabolised to produce energy, and it possesses anti-inflammatory effects; however, SMOFlipid emulsion use raises concerns regarding coagulopathy after LT. This study investigated the postoperative correlation between SMOFlipid and coagulation in LT. Materials and methods: The medical records of 54 recipients of living donor LT between January 2012 and June 2015 were retrospectively reviewed. Patients with pretransplant platelet count <40,000/µL and >40,000/µL were assigned to the non-SMOFlipid (n = 23) group and the SMOFlipid (n = 31) group, respectively. Results: The coagulation and nutrition profile of patients improved significantly after TPN support. No significant difference was observed in the coagulation profile between SMOFlipid and non-SMOFlipid groups. Although the SMOFlipid group exhibited a higher platelet count than the non-SMOFlipid group on day 7 (P < 0.001), no significant differences were observed in the platelet count on 14 and 30 days after TPN support between the 2 groups. Conclusion: TPN using SMOFlipid after LT is a good strategy for improving nutritional status without increasing the risks of bleeding and coagulation in patients intolerant of early enteral nutrition. Moreover, SMOFlipid use may not cause coagulopathy up to 14 days after LT. Overall, SMOFlipid provides nutritional benefits without increasing the risk of bleeding.

RESUMO

Increasing evidence has suggested that elevated systemic inflammation with a high neutrophil-lymphocyte ratio (NLR) is associated with poor prognosis after liver transplantation (LT). The ongoing molecular events involved in poor survival remain unclear. This retrospective study evaluated LT recipients whose data was collected at Kaohsiung Chang Gung Memorial Hospital between 2005 and 2014. Clinical records of 347 patients with hepatocellular carcinoma from seven days before LT to 30 days after LT illustrated that longitudinal values of lymphocytes, RBC, and hemoglobin were persistently low in patients with peritransplant high NLR (PTH-NLR, pre-LT ≥ 4 and post-LT ≥ 5), which indicated a significantly worse survival rate in association with increased RDW-CV and pancytopenia when compared to other patients (p = 0.008). We further found that PTH-NLR patients had decreased DNA damage response (DDR) genes and detoxifying enzymes of ADH and ALDH families, and increased mitochondrial stress response genes in their liver tissues. Reduced lineage markers of liver progenitor cells were also observed in PTH-NLR patients signifying the presence of unresolved impairments after LT. Our results demonstrate the association between hematopoietic deficiencies and lack of protection against DDR with PTH-NLR in LDLT recipients with HCC and may imply abnormal hematological and organismal defects in those patients.

RESUMO

BACKGROUND: Use of statins is associated with a reduced risk of hepatocellular carcinoma (HCC). However, the effect of statin use on HCC recurrence is unclear. This study aimed to evaluate the effect of statin use on recurrence after curative resection among patients with HCC. METHODS: We retrospectively assessed 820 patients with Barcelona Clinic Liver Cancer (BCLC) stage 0 or A HCC who underwent primary resection between January 2001 and June 2016 at Kaohsiung Chang Gung Memorial Hospital. Exposure to statins was defined as use of a statin for at least 3 months before HCC recurrence. Factors that influenced overall survival (OS) and recurrence-free survival (RFS) were analyzed using Cox proportional hazards models. RESULTS: Of the 820 patients, 46 (5.6%) used statins (statin group) and 774 (94.4%) did not (non-statin group). During the mean follow-up of 76.5 months, 440 (53.7%) patients experienced recurrence and 146 (17.8%) patients died. The cumulative incidence of HCC recurrence was significantly lower in the statin group than the non-statin group (p = 0.001); OS was not significantly different between groups. In multivariate analysis, age (hazard ratio [HR]: 1.291; p = 0.010), liver cirrhosis (HR: 1.743; p < 0.001), diabetes (HR:1.418; p = 0.001), number of tumors (HR: 1.750; p < 0.001), tumor size (HR: 1.406; p = 0.004) and vascular invasion (HR: 1.659; p < 0.001) were independent risk factors for HCC recurrence, whereas statin use (HR: 0.354; p < 0.001) and antiviral therapy (HR: 0.613; p < 0.001) significantly reduced the risk of HCC recurrence. The statin group still had lower RFS than the non-statin group after one-to-four propensity score matching. CONCLUSION: Statins may exert a chemo-preventive effect on HCC recurrence after curative resection.

RESUMO

BACKGROUND/AIMS: A recent study from the United States reported that nearly 12% of hepatocellular carcinomas (HCCs) occurred in patients without cirrhosis. Non-alcoholic fatty liver disease (NAFLD) was the most common liver disease in these patients. We aim to evaluate the characteristics, etiologies, and outcomes of cases of non-cirrhotic HCC in East Asia, where there is a higher prevalence of hepatitis B virus (HBV)-associated non-cirrhotic HCC. METHODS: This retrospective study consecutively enrolled de novo HCC patients managed at our institution from 2011 to 2017. The presence of cirrhosis was assessed by histology; if histology was not available, it was assessed by image study. RESULTS: 2055 patients with HCC were enrolled in this study. Among them, 529 (25.7%) were non-cirrhotic. The non-cirrhotic patients were younger (60.9 vs. 62.5 years, p = 0.006), included a greater proportion of males (78.1% vs. 71.3%, p = 0.002), and had a lower body mass index (24.3 vs. 25.3 kg/m2, p<0.001) than the cirrhotic patients. Among the non-cirrhotic patients, HBV was the most common liver disease (49.0%). The patients with non-cirrhotic HCC had larger tumors (5.9 vs. 4.7 cm, p<0.001), underwent liver resection at a higher rate (66.0% vs. 17.4%, p<0.001), and had better overall survival than the cirrhotic HCC patients (median 5.67 vs. 2.83 years, p<0.001). CONCLUSIONS: Nearly 26% of the HCCs occurred in patients without cirrhosis. HBV was the most common liver disease in these patients, and the survival was better in the non-cirrhotic patients than the cirrhotic patients.

RESUMO

BACKGROUND AND OBJECTIVES: A recent study proposed simple classifications of microscopic vascular invasion (MVI): microscopic portal vein invasion (MPVI) and microvessel invasion (MI). We aim to validate these classifications of MVI. METHODS: This retrospective study consecutively enrolled 514 Barcelona Clinic Liver Cancer stage 0, A, and B naïve hepatocellular carcinoma patients who underwent liver resection in our institution from 2011 to 2017. RESULTS: Among these 514 patients, 240 patients were classified as having no MVI at all (designated as no vascular invasion, NVI), 157 patients were classified as having MI only, and 117 patients were classified as having MPVI. The 5-year overall survival (OS) rate in the MI-only group was 83.3%, which was not significantly different from that of the NVI group (87.2%), p = .20. Using NVI as a reference, multivariate analysis showed that MI-only is not an independent variable associated with OS. The 5-year OS in the MPVI group was 59.2%, which was significantly lower than those for MI-only (p < .001) and NVI groups (p < .001). Using NVI as a reference, multivariate analysis showed that MPVI is an independent variable associated with OS (HR, 3.12; 95% CI, 1.80-5.40; p < .001). CONCLUSIONS: The results of this study validate the simple MVI classifications to be clinically useful.

RESUMO

To determine the optimal cutoff time point of early versus late recurrence relative to post-recurrence survival (PRS) among patients who underwent liver resection (LR) for hepatocellular carcinoma (HCC) in a high-volume liver surgery center in East Asia. This was a retrospective study. Patients who underwent LR for HCC between 2011 and 2018 at Kaohsiung Chang Gung Memorial Hospital were enrolled. The optimal cutoff time point to differentiate early versus late recurrence was evaluated relative to PRS. Among 826 patients, 282 (34.1%) of the patients experienced recurrence, with a median time to recurrence of 12.2 months. 6 months was defined as the optimal cutoff time point based on sensitivity analyses relative to PRS. Ninety (31.9%) of the patients developed early recurrence within 6 months, and 192 patients (68.1%) developed late recurrence beyond 6 months. Early recurrence was associated with worse PRS (median PRS, 13.2 versus 48.9 months, p < 0.001), as well as overall survival (OS) (median OS, 16.2 versus 65.4 months, p < 0.001), than late recurrence. Six months was identified as the cutoff time point to differentiate early versus late recurrence among patients undergoing LR for HCC.
