We retrospectively studied 16 (3 colonization and 13 infections) early post-liver transplant (≤60-day after transplantation) patients with vancomycin-resistant enterococci (VRE) colonization/infection from 2016 to 2019. All VRE isolates were

SUMMARY Background Multidrug-resistant (MDR) gram-negative bacterial (GNB) infections remain a significant cause of morbidity and mortality among surgical patients. The objective of our study was to recognize the risk factors for MDR GNB infection in patients with abdominal surgery and determine the predictors independently associated with death. Methods From 2010 to 2017, a retrospective cohort study was conducted among patients with abdominal surgery admitted in surgical intensive care unit (ICU). Patients with GNB infections were included for analyses. Results A total of 364 patients with abdominal surgery experienced GNB infections, among them, 117 (32.1%) were MDR GNB infection. Of 133 MDR GNB isolates, the most frequent isolate was Escherichia coli (45.1%). Patients with MDR GNB infection had significantly longer ventilator days and hospital stay, as well as higher 30-day and in-hospital mortality compared to non-MDR GNB patients. Multivariable analysis showed longer length of pre-ICU stay, surgical re-exploration, receipt of group 2 carbapenems (e.g. imipenem, meropenem and doripenem) and fluoroquinolones, and higher total bilirubin were independent risk factors for the acquisition of MDR GNB infection. Predictors for 30-day mortality among patients with MDR GNB infection were chronic kidney disease, receipt of group 2 carbapenems and inappropriate empirical antimicrobial therapy. Conclusions This study provides important information about the risk factors for subsequent MDR GNB infection and 30-day mortality among the patients with abdominal surgery.

PURPOSE To evaluate the prevalence and extension of macrovascular invasion (MaVI) in a large cohort of hepatocellular carcinoma (HCC) patients and analyze the association between MaVI and overall survival (OS). METHODS From 2011 to 2018, 2540 patients with newly diagnosed HCC who were managed in our institution were enrolled in this retrospective study. Tumor invasion of the intrahepatic branches of the portal or hepatic veins was defined as peripheral MaVI. Tumor invasion of the main portal vein or inferior vena cava was defined as central MaVI. RESULTS MaVI prevalence was 16.2% (n = 411). Among patients with Barcelona Clinic Liver Cancer (BCLC) stage C and Child-Pugh class A, 165 patients presented with peripheral MaVI and 89 patients with central MaVI. The median OS was 13.2 months (95% confidence interval [CI]: 11.4-15.4) in the peripheral MaVI group and 6.6 months (95% CI: 3.6-9.5) in the central MaVI group (p

Background Unequal access to healthcare is a global medical problem. Telemedicine, recently made possible by technological advances, may mitigate this inequity. However, the usefulness of telemedicine for procedure-driven disciplines, such as otolaryngology, under infectious conditions (e.g., the COVID-19 pandemic) is unknown. Methods Telemedicine was made legal in Taiwan by an amendment to the Physician Act in 2018. Kaohsiung Chang Gung Memorial Hospital was the first hospital in Taiwan to provide the telemedicine service by connecting to the Chenggong Branch of Taitung Hospital (CGBTH) in November 2018. This retrospective cohort study included all new and established otolaryngology outpatient consultations between November 2018 and May 2020 at CGBTH. The Current Procedural Terminology and International Classification of Disease, 10th Revision codes, patient demographic data, and questionnaire data were obtained. Results The study included 123 patients with 218 encounters over 19 months. The majority of complaints were ear-related (52.6%). Overall, 49% of the encounters required a specialized procedure for diagnosis and treatment; of these, cerumen removal was the most common procedure. The patient subjective improvement rate increased over the study period (from 62.0% to 78.9%). The rates of return and case closure were both around 90% in 2018 and 2019. The number of otolaryngology consultations and rate of return declined after the start of the COVID-19 pandemic; however, the subjective improvement and case closure rates remained stable. The telemedicine service saved at least 2 h driving time per visit. Conclusion Telemedicine for otolaryngology is a promising approach for remote and underserved regions, as well as during an infectious disease pandemic.

Background The approved dose of nivolumab is 3 mg/kg or a flat dose of 240 mg for indications. There is no dose-response relationship for nivolumab; therefore, a low-dose regimen may be an option to reduce financial toxicity. This study was designed to investigate the efficacy and safety of low-dose nivolumab in the management of hepatocellular carcinoma (HCC). Methods We retrospectively reviewed patients with HCC who received 20 or 100 mg of nivolumab intravenously every 2 weeks. The objective response rate was determined in accordance with the Response Evaluation Criteria in Solid Tumors criteria version 1.1. The Cox regression model and Kaplan–Meier method were used to analyze hazard factors, progression-free survival (PFS), and overall survival (OS). Adverse events (AEs) were assessed according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Results In total, 78 patients were enrolled, including 49 with hepatitis B virus (HBV) and 23 with hepatitis C virus (HCV). All patients were staged as Barcelona Clinic Liver Cancer stage C, and 20 patients were classified as having Child–Pugh classification B (7). Nivolumab 20 mg was an independent prognostic factor for better PFS, and albumin-bilirubin grade 1 was the independent prognostic factor for superior OS in the multivariate analyses. Patients with better HBV (HBV DNA Conclusion Low-dose nivolumab may be effective with manageable toxicity and can be an alternative option to reduce financial toxicity in patients with advanced HCC who cannot afford the high cost of immune checkpoint inhibitors in real-world practice.

Background. Despite the increasing number of laparoscopic hepatic procedures for the resection of hepatocellular carcinoma (HCC), intraoperative tumor localization and demarcation remains challenging in comparison to open surgery. In this study, we evaluated the feasibility of positive liver segment staining through the super-selective intra-arterial indocyanine green (ICG) administration. Methods. Eight patients presenting with a single HCC underwent an interventional vascular procedure followed by laparoscopic surgery. A microcatheter was advanced into the hepatic artery branches perfusing the HCC followed by digital subtraction angiography and angiography computed tomography (angio-CT). Patients were then transferred to the operating room, and a laparoscopic hepatectomy was performed under ultrasound guidance. A 5 mL bolus of ICG with a concentration of .125 mg/mL was injected through the microcatheter, and a near-infrared laparoscope was used to detect the fluorescence signal to assess the correspondence between the fluorescence-based demarcation and the intraoperative ultrasound–based demarcation. Results. The duration for the angiography procedure was 32.7 +/− 5.3 min, and it took 242 +/− 118 min from the end of angiography procedure until the start of the surgical procedure. In all cases, the fluorescent liver segment was corresponding to the angio-CT findings. In 6/8 cases, fluorescence imaging was considered helpful in the identification of the resection line. In 3 patients, the resection line was changed according to the positively stained liver segment. Conclusion. We successfully demonstrated the feasibility of the super-selective intra-arterial ICG administration for fluorescence-based positive staining of hepatic segmentation during laparoscopic surgery for HCC (NCT04266548).

Background/Purpose Population aging and unequal accessibility of health care are increasingly important in developed countries. One strategy to overcome these issues is utilizing telemedicine, which is recently made possible technologically by the advancement of internet speed, high speed zooming cameras, and the information storages. In Taiwan, the telemedicine is granted legally by the amendment for Taiwan's Physician Act in 2018. Methods Kaohsiung Chang Gung Memorial Hospital (Kaohsiung CGMH) is the first hospital in Taiwan to provide the telemedicine service connecting to Cheng Kung Branch of Taitung Hospital since Nov 2018. Consultation services from Dermatology, ENT, and Ophthalmology have been delivered in the live-interactive and face to face module every week. Results Dermatology consultation comprises the majorities. In the first year, there were totally 426 dermatology consultation services. Eczema, fungal infections, and scabies infestation were the three most common diseases in the beginning. The disease diagnosis became more diverse after several months, including some ready-to-treat diseases pending correct diagnosis, such as pediculosis, psoriasis, and urticaria. Coupled with dermoscopic images, diseases such as hair loss, pediculosis capitis, skin tumor, and scabies, were diagnosed promptly. The subjective patient improvement rate was more than 75% year-round and the case closure rate was more than 85% year-round. Conclusion Teledermatology is a promising approach to serve the remote medical-underprivileged regions. The teledermatology is anticipated to help underserved regions, nursing homes, prisons, and in situations with severe pandemic infections, such as COVID-19.

Background In the 8th edition of American Joint Committee on Cancer (AJCC) staging system for hepatocellular carcinoma (HCC), tumor size is not considered in T1 stage. The present study aimed to find out the optimal cutoff for tumor size to further stratify patients with T1 HCC. Methods Operated HCC patients were identified from the Chang Gung Research Database (CGRD), and the patients with T1bN0M0 tumors were further divided into two groups based on the tumor size. The resulting subgroups were denoted as T1b (≤ cutoff) and T1c (> cutoff). The survivals were compared between T1a/b and T1c as well as T1c and T2. Results From 2002 to 2018, a total of 2893 patients who underwent surgery for T1N0M0 HCC were identified from the CGRD. After excluding cases who died within 30 days of surgery, Kaplan–Meier survival analysis discovered that T1 tumors > 65 mm (T1c) had survivals similar to those of T2N0M0 tumors. Cox regression multivariate analysis further demonstrated that tumor size > 6.5 cm was an independent poor prognostic indicator for T1 HCC. Sensitivity tests also confirmed that tumors lager than 6.5 cm were significantly more likely to develop both tumor recurrence and liver-specific death after surgery. Conclusions Our study demonstrated that tumor size would significantly impact the survival outcome of T1 HCC after surgery. Due to significantly worse survival, we proposed a subclassification within T1 HCC, T1c: solitary tumor > 6.5 cm without vascular invasion, to further stratify those patients at risk. Further studies are mandatory to validate our findings.

BACKGROUND The Barcelona Clinic Liver Cancer (BCLC) guidelines were updated in 2012, and a single large hepatocellular carcinoma (HCC) more than 5 cm was regarded as BCLC stage A rather than B in the updated version. In this study, we sought to re-evaluate the outcomes of patients with HCC who underwent liver resection (LR) within (stage 0 and A) and beyond (stage B and C) the BCLC guideline recommendations of the updated BCLC staging system. METHODS This retrospective study enrolled 774 consecutive patients with naive HCC who underwent LR from 2011 to 2018 at our institution. The overall survival (OS) and recurrence-free survival (RFS) of these patients were examined. RESULTS Of the patients, 606 had BCLC stage 0 or A HCC, and 168 had BCLC stage B or C HCC. The 5-year OS and RFS among the patients within the BCLC criteria for LR were 75.2% and 56.1%, respectively, vs 54.9% and 34.0%, respectively, among the patients beyond the BCLC criteria (P

The albumin-bilirubin (ALBI) grade has been validated as a significant predictor for hepatocellular carcinoma (HCC). However, there is little information about the impact of postoperative ALBI grade in patients with HCC who are undergoing liver resection. We enrolled 525 HCC patients who received primary resection from April 2001 to March 2017. The impact of the pre- and post-operative ALBI grades on overall survival (OS) and recurrence-free survival (RFS) were analyzed by multivariate analysis. During the follow-up period (mean, 65 months), 253 (48.1%) patients experienced recurrence, and 85 (16.2%) patients died. Multivariate analysis revealed that diabetes mellitus (DM) (p = 0.011), alpha-fetoprotein levels (AFP) (p p = 0.008), liver cirrhosis (p p p = 0.006), DM (p = 0.002), AFP (p = 0.027), and ALBI grade at the first year after resection (p

A French study found that three preoperative factors (i.e. alpha-fetoprotein (AFP) 100 ng/ml, image-diagnosed tumor number 1, and cirrhosis) could predict non-transplantable recurrence (NTR) after liver resection (LR) for early-stage hepatocellular carcinoma (HCC). We aimed to evaluate whether this model could be applicable in an East Asian cohort from a country in which the majority of patients undergo living donor liver transplantation (LT). This retrospective study enrolled consecutive patients who underwent LR for transplantable HCC between 2011 and 2018 in our institution. The occurrence of NTR after LR was analyzed in a competing risks analysis, with death and transplantable recurrence as competing events. A total of 309 patients were included. The five-year overall survival and recurrence-free survival were 79.0% and 51.4%, respectively (median follow-up: 32.0 months). Recurrence was noted in 94 (30.4%) patients. NTR was noted in 35 (11.3%) patients. Univariate analysis showed that cirrhosis (sub-distribution hazard ratio (SHR) = 2.301, 95% CI = 1.046-5.065; p = 0.038) and image-diagnosed tumor number 1 (SHR = 2.32; 95% CI = 1.11-4.86; p = 0.026) were associated with NTR, whereas AFP 100 ng/ml (SHR = 1.56; 95% CI = 0.59-4.10; p = 0.37) was not associated with NTR. In the presence of 0, 1, and 2 factors (i.e. cirrhosis or image-diagnosed tumor number 1), the NTR rates were 7.2%, 10.8%, and 29.0%, respectively. The results showed that the French model was applicable to our cohort. In the presence of two factors (i.e. cirrhosis and image-diagnosed tumor number 1), risks and benefits of upfront LT could be discussed with the patient and the living donor.

The outcomes of minimally invasive surgery (MIS) vs. percutaneous radiofrequency ablation (RFA) in treating early-stage hepatocellular carcinoma (HCC) remain inconclusive. This study thus aimed to compare the outcomes of both treatments for early-stage HCCs.This retrospective study consecutively enrolled patients with newly diagnosed early-stage HCCs treated with MIS or percutaneous RFA between 2011 and 2018. Outcomes were compared between the MIS and RFA groups both before and after 1:1 propensity score matching (PSM).A total of 119 and 481 patients underwent MIS and percutaneous RFA, respectively. Patients undergoing percutaneous RFA exhibited older age (p = 0.007) and higher rates of Child-Pugh class B (p 0.001) and multifocal disease (p 0.001). The median overall survival (OS) was 73.7 months in the MIS group, which was significantly higher than that for the RFA group of 65.1 months (p = 0.003). 50% HCC recurrence after MIS was not reached. The mean recurrence-free survival (RFS) was 49.6 months for the MIS group, which was significantly higher than the RFA group of 41.3 months (p 0.001). On multivariate analysis, age ≥65 (HR: 1.61; 95% CI: 1.13-2.31, p = 0.009), RFA (HR: 2.21; 95% CI: 1.14-4.29, p = 0.019), and Child-Pugh class B (HR: 2.03; 95% CI: 1.29-3.21, p = 0.002) remained risk factors for OS, and RFA (HR: 2.18; 95% CI: 1.42-3.35; p 0.001) remained a risk factor for RFS. After PSM, 103 patients were included in each group. No significant difference in OS was identified (p = 0.198), but RFS was higher in the MIS group than the RFA group (p = 0.003). Severe postoperative complications occurred at the same rate (1%) in both groups (p 0.99).After PSM, severe postoperative complication and OS rates were found to be comparable between the MIS and RFA groups, but RFS was higher in the MIS group than the RFA group, suggesting that MIS may have better outcomes for patients with early-stage HCC.

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.

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.

Hepatocellular carcinoma (HCC) patients still have risk for very late recurrence after curative resection. This study assesses prognostic factors in HCC patients with recurrence-free survival (RFS) for 5 years after primary resection.We enrolled 383 HCC patients who received primary tumor resection and achieved more than 5 years without recurrence after resection between January 2001 and April 2013. Predictive factors, including albumin-bilirubin (ALBI) grade, for RFS and overall survival (OS) were analyzed.After a median follow-up of 103 months, 57 patients (14.9%) had recurrent HCC, and 14 (3.7%) died. Independent predictors for HCC recurrence were male sex (p = 0.035), pre-operative liver cirrhosis (LC) (p = 0.025), serum creatinine 1.5 mg/dL (p = 0.045), post-operative 5th-year alpha-fetoprotein (AFP) 15 ng/ml (p 0.001), LC (p = 0.004), and ALBI grades 2 and 3 (p 0.001). I ndependent risk factors for poor survival were age 70 years (p = 0.002), post-operative 5th-year AFP 15 ng/ml (p = 0.003), and ALBI grades 2 and 3 (p = 0.002). Patients whose deteriorated ALBI grades 5 years after resection had adverse RFS outcomes compared to those with constant (p = 0.056) and improved ALBI grades (p = 0.008). In subgroup analysis, patients with post-operative 5th-year ALBI grades 2 and 3 had significantly poorer RFS and OS (both p 0.001) than those with grade 1 among patients with low post-operative 5th-year AFP (15 ng/mL).In HCC patients without recurrence for 5 years after curative resection, post-operative 5th-year ALBI grade is useful for predicting outcomes, even with low AFP during follow-up.

Hepatic artery reconstruction (HAR) for liver transplantation is crucial for successful outcomes. We evaluated transplantation outcome improvement through continual technical refinements.HAR was performed in 1448 living donor liver transplants by a single plastic surgeon from 2008 to 2020. Difficult HARs were defined as graft or recipient hepatic artery ≤2 mm, size discrepancy (≥2 to 1), multiple hepatic arteries, suboptimal quality, intimal dissection of graft or recipient hepatic artery (HA), and immediate redo during transplantation. Technique refinements include early vessel injury recognition, precise HA dissection, the use of clips to ligate branches, an oblique cut for all HARs, a modified funneling method for size discrepancy, liberal use of an alternative artery to replace a pathologic HA, and reconstruction of a second HA for grafts with dual hepatic arteries in the graft.Difficult HARs were small HA (21.35%), size discrepancy (12.57%), multiple hepatic arteries (11.28%), suboptimal quality (31.1%), intimal dissection (20.5%), and immediate redo (5.18%). The overall hepatic artery thrombosis (HAT) rate was 3.04% in this series. The average HAT rate during the last 4 years (2017-2020) was 1.46% (6/408), which was significantly lower than the average HAT rate from 2008 to 2016 (39/1040, 3.8%) with a statistical significance (p = 0.025). Treatment for posttransplant HAT included anastomosis after trim back (9), reconstruction using alternatives (19), and nonsurgical treatment with urokinase (9).Careful examination of the HA under surgical microscope and selection of the appropriate recipient HA are key to successful reconstruction. Through continual technical refinements, we can reduce HA complications to the lowest degree.

FLD, older age group, and alcohol consumption are major risk factors of GBP formation in Taiwanese population. The presence of GBPs might be revealed in second-look examinations of abdominal sonographies.

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.

Colorectal cancer is a prevalent disease worldwide, with more than 50% of patients developing metastases to the liver. Despite advances in improving resectability, most patients present with non-resectable colorectal liver metastases requiring palliative systemic therapy and locoregional disease control strategies. There is a growing interest in the use of liver transplantation to treat non-resectable colorectal liver metastases in well selected patients, leading to a surge in the number of studies and prospective trials worldwide, thereby fuelling the emerging field of transplant oncology. The interdisciplinary nature of this field requires domain-specific evidence and expertise to be drawn from multiple clinical specialities and the basic sciences. Importantly, the wider societal implication of liver transplantation for non-resectable colorectal liver metastases, such as the effect on the allocation of resources and national transplant waitlists, should be considered. To address the urgent need for a consensus approach, the International Hepato-Pancreato-Biliary Association commissioned the Liver Transplantation for Colorectal liver Metastases 2021 working group, consisting of international leaders in the areas of hepatobiliary surgery, colorectal oncology, liver transplantation, hepatology, and bioethics. The aim of this study was to standardise nomenclature and define management principles in five key domains: patient selection, evaluation of biological behaviour, graft selection, recipient considerations, and outcomes. An extensive literature review was done within the five domains identified. Between November, 2020, and January, 2021, a three-step modified Delphi consensus process was undertaken by the workgroup, who were further subgrouped into the Scientific Committee, Expert Panel, and Transplant Centre Representatives. A final consensus of 44 statements, standardised nomenclature, and a practical management algorithm is presented. Specific criteria for clinico-patho-radiological assessments with molecular profiling is crucial in this setting. After this, the careful evaluation of biological behaviour with bridging therapy to transplantation with an appropriate assessment of the response is required. The sequencing of treatment in synchronous metastatic disease requires special consideration and is highlighted here. Some ethical dilemmas within organ allocation for malignant indications are discussed and the role for extended criteria grafts, living donor transplantation, and machine perfusion technologies for non-resectable colorectal liver metastases are reviewed. Appropriate immunosuppressive regimens and strategies for the follow-up and treatment of recurrent disease are proposed. This consensus guideline provides a framework by which liver transplantation for non-resectable colorectal liver metastases might be safely instituted and is a meaningful step towards future evidenced-based practice for better patient selection and organ allocation to improve the survival for patients with this disease.

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.

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

Curative resection is recommended for patient with early stage hepatocellular carcinoma (HCC), however, the prognosis is limited by high recurrence rate. This study was to investigate liver stiffness (LS) and metabolic factor in prediction of HCC recurrence for patients with early stage HCC who had undergone curative resection. Consecutive patients with suspicion of HCC who had undergone curative resection were prospectively enrolled. Transient elastography was performed to determine LS pre-operatively. The demographics, clinical characteristics and histological findings were recorded. All patients were followed up regularly until recurrence, death or last visit. Ninety-four patients with early stage HCC were enrolled. LS positively correlated with fibrosis stage (r = 0.666). In a median follow-up of 3.2 years, forty patients developed recurrences including 22 recurrences after 1-year post resection. The 5-year cumulative recurrence rate was 44.2%. LS was the independent factor associated with recurrence. Patients with LS > 8.5 kPa had higher 5-year cumulative recurrence rate (59.8% vs 25.1%, p = 0.007). For the prediction of recurrence after 1-year post resection, LS > 8.5 kPa (hazard ratio 2.72) and homeostatic model assessment for insulin resistance index (HOMA-IR) (hazard ratio 1.24) were independent factors in multivariate analysis. Those patients with both LS > 8.5 kPa and HOMA-IR > 2.3 had the highest recurrence rate after 1-year post resection.

Background Liver cirrhosis is a well-known risk factor of sepsis after emergent gastrointestinal (GI) endoscopy. Elective GI endoscopy before living donor liver transplantation (LDLT), however, may also carry the septic risk among these patients. Methods This retrospective study reviewed the medical records of 642 cirrhotic recipients who underwent GI endoscopy from 2008 to 2016. We analyzed the incidence and risk factors of post-endoscopy sepsis during 2008–2012 (experience cohort). Our protocol changed after 2013 (validation cohort) to include antibiotic prophylaxis. Results In experience cohort, 36 cases (10.5%) of the 342 LDLT candidates experienced sepsis within 48 h after endoscopy. The sepsis rate was significantly higher in patients with hepatic decompensation than patients without (22.2% vs. 9.6% vs. 2.6% in Child C/B/A groups respectively; ×2 = 20.97, P P Conclusions Patients with decompensated cirrhosis and hepatic hydrothorax have higher risk of sepsis following endoscopy. In advanced cirrhotic patients, antibiotic prophylaxis and drainage of hydrothorax may be required to prevent sepsis before elective GI endoscopy.

Background To date, the evidence on the safety and benefits of minimally invasive pancreatoduodenectomy (MIPD) in elderly patients is still controversy. This study aim to compare the risk and benefit between MIPD and open pancreatoduodenectomy (OPD) in elderly patients. Methods From 2016 to 2020, we retrospective enrolled 26 patients underwent MIPD and other 119 patients underwent OPD. We firstly compared the baseline characteristics, 90-day mortality and short-term surgical outcomes of MIPD and OPD. Propensity score matching was applied for old age patient (≥ 65-year-old vs. Results Patients received MIPD is significantly older, had poor performance status, less lymph node harvest, longer operation time, less postoperative hospital stay (POHS) and earlier drain removal. After 1:2 propensity score matching analysis, elderly patients in MIPD group had significantly poor performance status (P = 0.042) compared to OPD group. Patients receiving MIPD had significantly shorter POHS (18 vs. 25 days, P = 0.028), earlier drain removal (16 vs. 21 days, P = 0.012) and smaller delay gastric empty rate (5.9 vs. 32.4% P = 0.036). There was no 90-day mortality (0% vs. 11.8%, P = 0.186) and pulmonary complications (0% vs. 17.6%, P = 0.075) in MIPD group, and the major complication rate is comparable to OPD group (17.6% vs. 29.4%, P = 0.290). Conclusion For elderly patients, MIPD is a feasible and safe option even in patients with inferior preoperative performance status. MIPD might also provide potential advantage for elderly patients in minimizing pulmonary complication and overall mortality over OPD.

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).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).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-fetoprotein20 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).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.

Background Non-invasive techniques for liver fibrosis diagnosis are very important for clinician especially in high-risk patients for liver biopsy. We further explored the diagnostic accuracy of FibroScan, FIB-4 and aminotransferase-to-platelet ratio index (APRI) in identifying liver fibrosis and assess their predictive role for oesophageal varices in patients with hepatocellular carcinoma (HCC). Methods In total, 380 patients who underwent surgery for HCC were included based on retrospective study design. Liver fibrosis was pathologically diagnosed using the Ishak scoring system. Liver stiffness parameters were measured using FibroScan. APRI and FIB-4 were calculated. Among those, 121 patients who received oesophagogastroduodenoscopic examination underwent variceal evaluation. Results For liver cirrhosis diagnosis with FibroScan, the optimal cut-off values for the patients with HCC overall, left HCC and right HCC were 8.85, 11.75 and 8.70 kPa (the accuracy were 78.7%, 78.4% and 79.2%, respectively). They had high areas under the receiver operating characteristic curve of 0.84, 0.84 and 0.85. The combined FibroScan, APRI and FIB-4 had very high specificity (more than 92%) for cirrhosis diagnosis. The optimal cut-off liver stiffness values for the diagnosis of varices were all 11.2 kPa. For predicting varices, the optimal cut-off values of FIB-4 and APRI were 2.64 and 0.71, their accuracy were 64.3%-78.4%, 69.4% and 72.7%, respectively. Conclusions FibroScan, FIB-4 and APRI have moderate accuracy for liver fibrosis diagnosis and oesophageal varices prediction in patients with hepatoma. This is a study of these non-invasive techniques applied in specific hepatoma patients and with inevitable limitations and need future more studies for validation.

Background Metformin is proposed to have chemopreventive effect of various cancer currently. However, the anti-cancer effect of metformin for diabetic patients with hepatocellular carcinoma (HCC) undergoing liver resection remains unclear. The aim of our cohort study was to assess whether metformin influence the recurrence of HCC. Methods We retrospectively enrolled 857 HCC patients who received primary resection from April 2001 to June 2016. 222 patients were diagnosed with diabetes mellitus (DM) from medical record. Factors influence the overall survival (OS) and recurrence-free survival (RFS) were analyzed by multivariate analysis. Results During the follow-up period (mean, 75 months), 471 (54.9%) patients experienced recurrence, and 158 (18.4%) patients died. Multivariate analysis revealed that DM (p = 0.015), elevated AST (p = 0.006), hypoalbuminemia (p = 0.003), tumor number (p = 0.001), tumor size (p < 0.001), vascular invasion (p p p = 0.014), hepatitis C (p = 0.001) were independent predictors for RFS. In diabetic patients, only HbA1c>9% (p = 0.033), hypoalbuminemia (p = 0.030) and vascular invasion (p = 0.001) were independent risk factors for HCC recurrence; but the metformin use revealed no significance on recurrence. DM is a risk factor of HCC recurrence after resection. Adequate DM control can reduce the recurrence of HCC. However, the use of metformin does not reduce the risk of HCC recurrence in diabetic patient after initial resection. Hence, metformin may not have protective influences on HCC recurrence in diabetic patients who undergo initial liver resection.

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 p = 0.001), number of tumors (HR: 1.750; p p = 0.004) and vascular invasion (HR: 1.659; p p p Conclusion Statins may exert a chemo-preventive effect on HCC recurrence after curative resection.

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 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.

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.

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

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.

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 naive 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

Background The outbreak of Covid-19 has vastly increased the operational burden on healthcare systems worldwide. For patients with end-stage liver failure, liver transplantation is the only option. However, the strain on intensive care facilities caused by the pandemic is a major concern. There is an urgent need for ethical frameworks to balance the need for liver transplantation against the availability of national resources. Methods We performed an international multi-center study of transplant centers to understand the evolution of policies for transplant prioritization in response to the pandemic in March 2020. To describe the ethical tension arising in this setting, we propose a novel ethical framework, the Quadripartite Equipoise (QE) score, that is applicable to liver transplantation in the context of limited national resources. Results Seventeen large- and medium- sized liver transplant centers from twelve countries across four continents participated. Ten centers opted to limit transplant activity in response to the pandemic, favoring a “sickest-first” approach. Conversely, some larger centers opted to continue routine transplant activity in order to balance waiting list mortality. To model these and other ethical tensions, we computed a QE score using 4 factors - Recipient Outcome, Donor/Graft Safety, Waiting List Mortality and Healthcare Resources for seven countries. The fluctuation of the QE score over time accurately reflects the dynamic changes in the ethical tensions surrounding transplant activity in a pandemic. Conclusions This four-dimensional model of Quadripartite Equipoise addresses the ethical tensions in the current pandemic. It serves as a universally applicable framework to guide regulation of transplant activity in response to the increasing burden on healthcare systems to allow greater global solidarity and transparency in these austere times., Graphical abstract, HIGHLIGHTS • Increased operational burden on healthcare systems worldwide from Covid-19 outbreak • Frameworks to balance need for liver transplant against limited resources needed • International multi-center study of policies for transplant prioritization conducted • Novel four-dimensional model of Quadripartite Equipoise to balance ethical tensions • Fluctuation of model over time guides need to pursue or limit transplant activity, There is an urgent need for ethical frameworks to balance the need for liver transplantation against the availability of national resources in the Covid-19 pandemic. We describe a four-dimensional model of Quadripartite Equipoise that models these ethical tensions and can guide the regulation of transplant activity in response to the increasing burden on healthcare systems.

The gut microbiota plays a role in nonalcoholic fatty liver disease (NAFLD), but data about gut dysbiosis in Asians with NAFLD remains scarce. We analyzed the differences in fecal microbiota between adults with and without NAFLD. This cross-sectional study examined adults with histology-proven NAFLD (25 nonalcoholic fatty liver (NAFL) patients, 25 nonalcoholic steatohepatitis (NASH) patients, and 25 living liver donors (healthy controls)). The taxonomic composition of the gut microbiota was determined by 16S ribosomal RNA gene sequencing of stool samples. The NAFL and NASH groups showed lower total bacterial diversity and richness than the controls. NAFLD patients had higher levels of the phylum Bacteroidetes and lower levels of Firmicutes than controls. The genus Ruminococcaceae UCG-010, family Ruminococcaceae, order Clostridiales, and class Clostridia were less abundant in patients with NAFL or NASH than healthy individuals. The lipopolysaccharide biosynthesis pathway was differentially enriched in the NASH group. This study examined the largest number of Asian patients with biopsy-proven NAFL and NASH in terms of dysbiosis of the gut microbiota in NAFLD patients. NAFLD patients had higher levels of Bacteroidetes and lower levels of Firmicutes. These results are different from research from western countries and could provide different targets for therapies by region.

Background & aimsIn 2012, the Barcelona Clinic Liver Cancer (BCLC) system designated a single large hepatocellular carcinoma (SLHCC) (>5 cm) as BCLC stage A rather than stage B. However, a recent study from western countries reported that prognosis following liver resection (LR) among patients with SLHCC was similar to that among patients with BCLC stage B. We aim to evaluate the prognosis following LR among patients with SLHCC from an Asian high-volume liver surgery center.MethodsPatients who underwent curative-intent LR for histologically proven HCC between 2011 and 2017 were enrolled using an HCC registry database. Overall survival (OS) among patients with BCLC stages 0, A, and B was examined. Patients with a SLHCC were classified as BCLC stage A1.ResultsAmong 543 patients, 89 (16.4%) were BCLC stage 0, 289 (53.2%) were BCLC stage A, 92 (16.9%) were BCLC stage A1, and 73 (13.4%) were BCLC stage B. The median follow-up was 38 months. The five-year OS rates among patients with BCLC stages 0, A, A1, and B were 83.5%, 83.7%, 77.4%, and 55.4%, respectively (pConclusionPrognosis following LR among patients with SLHCC was similar to that among patients with BCLC stage A. The prognosis for SLHCC should thus be considered comparable to that for BCLC stage A.

Epidemic viral infections, including the outbreak of severe acute respiratory syndrome (SARS) in 2003 and SARS-CoV-2 in 2019, have brought tremendous loss to people across the nations. The aim of this study was to compare the psychological impact of the SARS-CoV-2 pandemic in 2020 and the SARS pandemic in 2003 on hospital workers. Hospital workers at a medical center in Southern Taiwan (n = 1816) were invited to complete questionnaires (SARS-CoV-2 Exposure Experience, the Impact of Event Scale, the Chinese Health Questionnaire, and the Distress Thermometer). The current data were compared to the data collected from hospital workers (n = 1257) at the same medical center during the SARS pandemic in 2003. We found the psychological impact on hospital workers during the SARS-CoV-2 pandemic was significantly lower than that during the previous SARS period. During the SARS-CoV-2 pandemic period, hospital workers with SARS experience were more accepting of the risk, felt a greater responsibility to take care of the SARS-CoV-2 patients, and were more likely to perceive the danger of becoming infected. The associated factors of psychiatric morbidity in hospital workers with SARS experience were being female, the degree of intrusion severity, and severity of psychological distress. Proper management strategies and lessons learned from the SARS experience might have led to low psychiatric morbidity during the SARS-CoV-2 pandemic.

Mammalian targets of rapamycin inhibitors (mTORIs), including sirolimus and everolimus, are used for minimizing calcineurin inhibitors after liver transplantation. However, head-to-head randomized comparisons of these 2 mTORIs are lacking. We assessed the differences in renoprotection and possible mechanisms between sirolimus and everolimus in liver transplant recipients. For this prospective cohort study, we recruited liver transplant recipients whose regimens were switched from tacrolimus to sirolimus or everolimus at a Taiwan medical center. Serial changes in estimated glomerular filtration rate (eGFR), urinary N-acetyl-β-D-glucosaminidase, neutrophil gelatinase-associated lipocalin, 8-hydroxy-2'-deoxyguanosine, and transforming growth factor-β1 during 1 year after mTORI conversion were compared within and between groups. In the 61 patients analyzed, no significant change in eGFR occurred within 12 months after conversion in both mTORI groups. Among patients with baseline eGFR

Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality in Taiwan. To help clinical physicians to manage patients with HCC, the Taiwan Liver Cancer Association and the Gastroenterological Society of Taiwan produced the management consensus guideline for HCC. Methods: The recommendations focus on nine important issues on management of HCC, including surveillance, diagnosis, staging, surgery, local ablation, transarterial chemoembolization/transarterial radioembolization/hepatic arterial infusion chemotherapy, systemic therapy, radiotherapy, and prevention. Results: The consensus statements were discussed, debated and got consensus in each expert team. And then the statements were sent to all of the experts for further discussion and refinement. Finally, all of the experts were invited to vote for the statements, including the level of evidence and recommendation. Conclusion: With the development of the management consensus guideline, HCC patients could benefit from the optimal therapeutic modality. Keywords: Diagnosis, Hepatocellular carcinoma, Staging, Surveillance, Treatment

BACKGROUND Liver transplantation (LT) is the best radical treatment of hepatocellular carcinoma (HCC). Salvage liver transplantation (SalvLT) provides good outcomes for recurrent HCC cases after initial curative liver resection (LR). However, the salvage strategy is not feasible in all situations due to aggressive recurrences. Recently, sequential liver transplantation (SeqLT) was proposed for cases that show adverse pathological features after LR, thus LT is performed pre-emptively before recurrence. In this report, we compared the outcomes of SalvLT and SeqLT for surgical treatment of HCC. MATERIAL AND METHODS One hundred and ten cases underwent LR for HCC, then were subjected to either SalvLT (n=91) or SeqLT (n=19), from January 2001 to December 2015. For cases that underwent several LR before LT, we collected the data of the last LR before transplantation. A comparison was made according to pre- and post-transplant clinical and pathological variables. Survival analysis and comparison between both pathways are provided. RESULTS The median interval (months) between LR and LT for the SeqLT group and the SalvLT group were 9.6 and 22.2, respectively. (p=0.01). The LR histopathological features were similar in both groups. In the SalvLT group, the histopathological comparison between the criteria of last LR and the criteria of liver explants revealed that 14 cases advanced from stage I to stage II, one cases from stage I to stage IIIa, one case from stage I to stage IIIb, one case from stage I to stage IIIc, three cases from stage II to stage IIIb and one case from stage II to stage IIIc. The overall rate of pathological upstaging in the SalvLT group was 27%. The incidence of post-transplant HCC recurrence was 5% (1/19) and 11% (10/91) for the SeqLT and SalvLT groups, respectively (p=0.4). The incidence of post-LT in-hospital mortality was 0% among the SeqLT group and 2% (2/91) among the SalvLT group. The estimated rates of five-year overall survival and cancer specific survival for the SeqLT group versus the SalvLT group were (92.3% versus 87.6%; p=0.4) and (92.3% versus 91.9%; p=0.7), respectively. CONCLUSIONS The SeqLT approach might be associated with low incidence of cancer recurrence, better overall survival, and less operative mortality. Another possible benefit is the avoidance of aggressive non-transplantable HCC recurrences. More studies and/or randomization are required for highre evidence conclusions.

Surgical management of centrally located hepatocellular carcinoma (CL-HCC) poses a great challenge. Major hepatectomy (MH) might compromise future remnant liver volume (FRLV), while the long-term benefits of central hepatectomy (CH) had not been well demonstrated. Consecutive patients with early-stage CL-HCC who underwent liver resection were enrolled. Fifteen patients underwent CH, while thirty-three were subjected to MH. All relevant clinicopathological variables were analyzed. Disease-free survival (DFS) and overall survival (OS) of both groups were compared. There were no differences between CH and MH in terms of predisposing liver disease, tumor size, blood loss, complication rate and vascular invasion. Mean FRLV increased from 40.9 to 69.2% by using CH resection lines. The parenchymal transection time is longer in CH. There were no differences of DFS between two groups. The 5-year OS rates of CH and MH were 93.3 and 62.6%, respectively. MH was a poor prognostic factor. CH is a relatively time-consuming and technique-demanding procedure, but excellent long-term survival could be achieved. CH could increase liver volume preservation without compromising intra-hepatic recurrence. In an endemic area of hepatitis and cirrhosis, CH should still play an important role in surgical treatment of CL-HCC.

The prognostic significance of sarcopenia has been widely studied in different cancer patients. This study aimed to analyze the influence of sarcopenia on long-term survival in patients with colorectal liver metastasis (CRLM) undergoing hepatic resection. A retrospective analysis of 182 patients undergoing hepatic resection for CRLM was performed. Sarcopenia was determinedusing the Hounsfield unit average calculation (HUAC), a measure of muscle quality-muscledensity at preoperative abdominal computed tomography scans. Sarcopenia was defined as an HUAC score of less than 22 HU calculated using receiver operating characteristic analysis. The prognostic relevance of clinical variables and overall survival (OS) and recurrence-free survival (RFS) was evaluated. Patients with sarcopenia were older (p p = 0.004), higher body mass index (BMI) (p p = 0.026) compared to those without. Sarcopenia was not significantly associated with OS and RFS. Multivariate Cox’s regression analysis showed that multinodularity (>3) (hazard ratio (HR) 2.736; 95% confidence interval (CI), 1.631–4.589; p p = 0.021) and blood loss (≥300 cc) (HR1.793; 95% CI, 1.084–2.964; p = 0.023) were independent factors associated with OS. In subgroup analyses, sarcopenia was a significant factor of poor OS in the patients with multinodularity by univariate (p = 0.002) and multivariate analyses(HR 3.571; 95% CI, 1.508–8.403; p = 0.004). Multinodularity (>3) (HR 1.750; 95% CI, 1.066–2.872; p = 0.027), high aspartate aminotransferase level (HR 1.024; 95% CI, 1.003–1.046; p = 0.025) and male gender (HR 1.688; 95% CI, 1.036–2.748; p = 0.035) were independent factors of RFS. In conclusion, despite no significance in whole cohort, sarcopenia was predictive of worse OS in patients with multiple CRLM after partial hepatectomy.

Tumor histology affects outcome after liver transplantation (LT) for hepatocellular carcinoma (HCC). This study explores the association between F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) and tumor histology in living donor liver transplantation (LDLT) recipients and their outcome.Two hundred fifty-eight patients with primary liver tumors who underwent FDG-PET before LDLT were enrolled in this retrospective study. Unfavorable tumor histology was defined as primary liver tumor other than a well- or moderately differentiated HCC. Thirteen patients had unfavorable tumor histology, including 2 poorly differentiated HCC, 2 sarcomatoid HCC, 5 combined hepatocellular cholangiocarcinoma, 3 intrahepatic cholangiocarcinoma, and 1 hilar cholangiocarcinoma.FDG-PET positivity was significantly associated with unfavorable tumor histology (P0.001). Both FDG-PET positivity and unfavorable tumor histology were significant independent predictors of tumor recurrence and overall survival. In a subgroup analysis of patients with FDG-PET-positive tumors, unfavorable tumor histology was a significant independent predictor of tumor recurrence and overall survival. High FDG uptake (tumor to non-tumor uptake ratio ≥ 2) was a significant predictor of unfavorable tumor histology. Patients with high FDG uptake and/or unfavorable tumors had significantly higher 3-year cumulative recurrence rate (70.8% versus 26.2%, P = 0.004) and worse 3-year overall survival (34.1% versus 70.8%, P = 0.012) compared to those with low FDG uptake favorable tumors.The expression of FDG-PET is highly associated with histology of explanted HCC and predicts the recurrence. FDG-PET-positive tumors with high FDG uptake may be considered contraindication for LDLT due to high recurrence rate except when pathology proves favorable histology.

Currently, there is no definitive management for hepatocellular carcinoma (HCC) intrahepatic recurrence (IHR) after primary resection (PR). The aim of this study was to analyze the outcomes of three modalities for patients who received curative PR and had IHR within the University of California San Francisco (UCSF) criteria.Between 2003 and 2010, patients with IHR after PR were treated with salvage liver transplantation (SLT), re-resection (RR) or local ablation (LA). Clinico-pathological features of primary tumor and recurrent HCC were analyzed to determine the risk factors that adversely affected overall survival (OS) and disease free survival (DFS).The study included 130 patients with subgroups of SLT (n = 25), RR (n = 31) and LA (n = 74). The 5-year DFS and OS were 75%, 31% and 17% and 80%, 60% and 58% respectively for each subgroup. SLT had a significantly better DFS than other modalities (p0.001). There was no difference in OS. In multivariate analysis, two variables adversely affected DFS: microvascular invasion in PR and not treating patients with SLT.SLT provides better DFS for patients with IHR within the UCSF criteria. However, SLT failed to show the same advantage in OS.

Salvage liver transplantation (LT) provides definite treatment for recurrent hepatocellular carcinoma (HCC) after primary liver resection. However, salvage living donor LT (SLDLT) involves more surgical difficulty, compared to local regional therapy (LRT). The optimal treatment strategy remains unclear. This study aims to compare the survival between SLDLT and LRT for patients with recurrent HCC after primary hepatic resection in a single center. Between 2001 and 2010, 211 patients with recurrent HCC after primary liver resection and a certain Milan criteria were enrolled. Among these patients, 41 and 170 patients received SLDLT and LRT, respectively. Clinical parameters were analyzed in terms of overall survival by multivariate analysis. The 1-, 3-, and 5-year overall survival rates were 90.2, 80.4, and 80.4 % in the SLDLT group, and 91.6, 71.7, and 51.1 % in LRT group, respectively. A paradoxical phenomenon of survival was noticed—a poorer survival rate within the first year in the SLDLT group but a better one after that year. For patients who survived more than 1 year, the SLDLT led to significantly better survival outcomes than LRT (P

Background Massive bleeding during liver transplantation (LT) is difficult to manage surgical event. Perihepatic packing (PP) and temporary abdominal closure (TAC) with delayed biliary reconstruction (DBR) can be applied in these circumstances. Method A prospective database of LT in a major transplant center was analyzed to identify patients with massive uncontrollable bleeding during LT that was resolved by PP, TAC, and DBR. Results From January 2009 to July 2013, 20 (3.6%) of 547 patients who underwent LT underwent DBR. Mean intraoperative blood loss was 20,500 ml at the first operation. The DBR was performed with a mean of 55.2 h (16–110) after LT. Biliary reconstruction included duct-to-duct (n = 9) and hepatico-jejunostomy (n = 11). Complications occurred in eight patients and included portal vein thrombosis, cholangitis, severe bacteremia, pneumonia. There was one in-hospital death. In the follow-up of 18 to 33 months we have seen one patient died 9 months after transplantation. The remaining 18 patients are alive and well. Conclusions In case of massive uncontrollable bleeding and bowel edema during LT, the combined procedures of PP, TAC, and DBR offer an alternatively surgical option to solve the tough situation.
