[Diabetes and pancreas or islet transplantation: psychological issues]. / Diabète et transplantation du pancréas ou d'îlots de Langerhans : enjeux psychologiques.

Diabetes is a chronic and progressive disease that affects an increasing number of patients. The prevalence of associated psychological comorbidities is high and often requires the implementation of targeted psychological interventions. Pancreas or islet transplantation remains a therapeutic option to consider, for a part of patients with type 1 diabetes unstable disease or established complications. From the clinical indication to the waiting period for a transplantation, then to the postoperative and long-term care, the diabetic patient is found to experience perpetual changes that may test his adaptability. In this article, the psychological aspects of the pancreas or islet transplantation, as well as the role of a liaison psychiatrist in a transplantation unit will be discussed.

Le diabète est une maladie chronique et évolutive atteignant un nombre croissant de patients. La prévalence des comorbidités psychiques associées est élevée et nécessite souvent l'implémentation d'interventions psychologiques ciblées. La transplantation du pancréas ou d'îlots de Langerhans est une option thérapeutique à considérer pour certains patients avec un diabète de type 1 instable ou des complications installées. De l'indication clinique à la période d'attente pour une greffe, puis des suites postopératoires jusqu'à la vie d'après la greffe, le patient diabétique vit des transitions multiples le mettant à l'épreuve. Dans cet article, nous discutons les aspects psychologiques de ces transplantations ainsi que les interventions du psychiatre de liaison au sein d'un service de transplantation.

Utilization of livers donated after circulatory death for transplantation - An international comparison.

BACKGROUND & AIMS: Liver graft utilization rates are a hot topic due to the worldwide organ shortage and the increasing number of transplant candidates on waiting lists. Liver perfusion techniques have been introduced in several countries, and may help to increase the organ supply, as they potentially enable the assessment of livers before use. METHODS: Liver offers were counted from donation after circulatory death (DCD) donors (Maastricht type III) arising during the past decade in eight countries, including Belgium, France, Italy, the Netherlands, Spain, Switzerland, the UK, and the US. Initial type-III DCD liver offers were correlated with accepted, recovered and implanted livers. RESULTS: A total number of 34,269 DCD livers were offered, resulting in 9,780 liver transplants (28.5%). The discard rates were highest in the UK and US, ranging between 70 and 80%. In contrast, much lower DCD liver discard rates, e.g. between 30-40%, were found in Belgium, France, Italy, Spain and Switzerland. In addition, we observed large differences in the use of various machine perfusion techniques, as well as in graft and donor risk factors. For example, the median donor age and functional donor warm ischemia time were highest in Italy, e.g. >40 min, followed by Switzerland, France, and the Netherlands. Importantly, such varying risk profiles of accepted DCD livers between countries did not translate into large differences in 5-year graft survival rates, which ranged between 60-82% in this analysis. CONCLUSIONS: Overall, DCD liver discard rates across the eight countries were high, although this primarily reflects the situation in the Netherlands, the UK and the US. Countries where in situ and ex situ machine perfusion strategies were used routinely had better DCD utilization rates without compromised outcomes. IMPACT AND IMPLICATIONS: A significant number of Maastricht type III DCD livers are discarded across Europe and North America today. The overall utilization rate among eight Western countries is 28.5% but varies significantly between 18.9% and 74.2%. For example, the median DCD-III liver utilization in five countries, e.g. Belgium, France, Italy, Switzerland, and Spain is 65%, in contrast to 24% in the Netherlands, UK and US. Despite this, and despite different rules and strategies for organ acceptance and preservation, 1- and 5-year graft survival rates remain fairly similar among all participating countries. A highly varying experience with modern machine perfusion technology was observed. In situ and ex situ liver perfusion concepts, and application of assessment tools for type-III DCD livers before transplantation, may be a key explanation for the observed differences in DCD-III utilization.

Renoportal Anastomosis During Liver Transplantation in Patients With Portal Vein Thrombosis: First Long-term Results From a Multicenter Study.

OBJECTIVE: To evaluate the short- and long-term outcomes of RPA in a large multicentric series. SUMMARY BACKGROUND: The current knowledge on RPA for portal reconstruction during LT in patients with diffuse PVT and a large splenorenal shunt is poor and limited to case reports and small case series. METHODS: All consecutive LTs with RPA performed in 5 centers between 1998 and 2020 were included. RPA was physiological provided it drained the splanchnic venous return through a large splenorenal shunt (≥ 1 cm diameter). Complications of PHT, long-term RPA patency, and patient and graft survival were assessed. RPA success was achieved provided the 3 following criteria were all fulfilled: patients were alive with patent RPA and without clinical PHT. RESULTS: RPA was attempted and feasible in 57 consecutive patients and was physiological in 51 patients (89.5%). Ninety-day mortality occurred in 5 (8.5%) patients, and PHT-related complications occurred in 42.9% of patients. With a median follow-up of 63 months, the 1-, 3- and 5-year patient and graft survival rates were 87%, 83%, and 76% and 82%, 80%, and 73%, respectively. The primary and primary-assisted patency rates at 5 years were 84.5% and 94.3%, respectively. Success was achieved in 90% (27/30) of patients with a follow-up ≥5 years. CONCLUSIONS: Despite a high rate of PHT-related complications, excellent long-term patient and graft survival could be achieved. RPA could be considered successful in the vast majority of patients. The expanded use of RPA is warranted.

Impact of the presence of median arcuate ligament on biliary complications after liver transplantation.

INTRODUCTION: The presence of median arcuate ligament (MAL) during orthotopic liver transplantation (OLT) may cause a significant reduction in the arterial hepatic flow. The aim of the present study is to investigate the impact of MAL on biliary complications in patients who underwent OLT. METHODS: We performed a retrospective case-control study among patients who underwent OLT in Geneva University Hospital between 2007 and 2017, depending on the presence or absence of MAL. The matching was performed according to age, gender, lab-MELD score at the time of OLT and type of donor (living or dead). The presence of MAL was assessed by an expert liver radiologist on the preoperative CT angiographic evaluation. RESULTS: The incidence of MAL was 6.1% (19 patients). Baseline characteristics were comparable between the two groups. No significant difference in biliary complications was found between patients with and without MAL (37% and 24%, respectively). No patient presented hepatic artery thrombosis. After logistic regression, in patients with MAL, the MAL release and gastroduodenal artery preservation compared to no treatment, showed an odds ratio for post-OLT biliary complications of 1.5 and 1.25, respectively. There was no difference in overall graft survival and in hazard for biliary complications between patients with and without MAL. CONCLUSION: In the present study, we did not find any difference in the prevalence of biliary and arterial complications between patients with and without MAL. The choice of MAL treatment did not influence in a significant way the overall outcome and development of complications. However, if, at the end of arterial reconstruction, the arterial flow is not adequately established, MAL needs to be treated with the least invasive technique.

Artificial Intelligence: Present and Future Potential for Solid Organ Transplantation.

Artificial intelligence (AI) refers to computer algorithms used to complete tasks that usually require human intelligence. Typical examples include complex decision-making and- image or speech analysis. AI application in healthcare is rapidly evolving and it undoubtedly holds an enormous potential for the field of solid organ transplantation. In this review, we provide an overview of AI-based approaches in solid organ transplantation. Particularly, we identified four key areas of transplantation which could be facilitated by AI: organ allocation and donor-recipient pairing, transplant oncology, real-time immunosuppression regimes, and precision transplant pathology. The potential implementations are vast-from improved allocation algorithms, smart donor-recipient matching and dynamic adaptation of immunosuppression to automated analysis of transplant pathology. We are convinced that we are at the beginning of a new digital era in transplantation, and that AI has the potential to improve graft and patient survival. This manuscript provides a glimpse into how AI innovations could shape an exciting future for the transplantation community.

[Malignant lesions of the extrahepatic biliary system]. / Prise en charge du cholangiocarcinome extrahépatique.

This article provides an overview of recent advances in the diagnosis and treatment of extrahepatic cholangiocarcinomas (EH-CCAs), focusing on the role of endoscopy, surgery, and transplantation. It reviews optimal evaluation and management of patients with EH-CCA, including a careful integration of clinical information, imaging studies, cytology and/or histology, as well as a coordinated multidisciplinary approach. It reviews additional therapy such as radio- or chemotherapy either in the neoadjuvant or adjuvant setting. Furthermore, it addresses palliative approaches as well as emerging targeted therapy and immunotherapy. EH-CCAs account for nearly 90% of biliary tract malignancies and present an ongoing challenge for hepatobiliary surgeons.

Cet article apporte une vision globale des avancées récentes dans le diagnostic et la prise en charge des cholangiocarcinomes extrahépatiques (CCA-EH), en décrivant les rôles respectifs de l'endoscopie, de la chirurgie et de la transplantation. L'évaluation et la prise en charge sont abordées en intégrant les informations cliniques, les différentes modalités d'imagerie, la cytologie et/ou la pathologie, à travers une approche multidisciplinaire. Nous abordons également les tendances épidémiologiques et les facteurs de risque nouvellement identifiés ainsi que l'apport de la radiochimiothérapie. L'approche palliative, tout comme les thérapies ciblées ou l'immunothérapie sont également discutées. Les CCA-EH représentent 90 % des cancers des voies biliaires et constituent un défi permanent pour les chirurgiens hépatobiliaires.

Predicting recurrence of hepatocellular carcinoma after liver transplantation using a novel model that incorporates tumor and donor-related factors.

Evidence suggests that liver graft quality impacts on posttransplant recurrence of hepatocellular carcinoma (HCC). As of today, selection criteria only use variables related to tumor characteristics. Within the Scientific Registry of Transplant Recipients, we identified patients with HCC who underwent liver transplantation between 2004 and 2016 (development cohort, n = 10 887). Based on tumor recurrence rates, we fitted a competing-risk regression incorporating tumor- and donor-related factors, and we developed a prognostic score. Results were validated both internally and externally in the Australia and New Zealand Liver Transplant Registry. Total tumor diameter (subhazard ratio [sub-HR] 1.52 [1.28-1.81]), alpha-feto protein (sub-HR 1.27 [1.23-1.32], recipient male gender (sub-HR 1.43 [1.18-1.74]), elevated donor body mass index (sub-HR 1.26 [1.01-1.58]), and shared graft allocation policy (sub-HR 1.20 [1.01-1.43]) were independently associated with tumor recurrence. We next developed the Darlica score (sub-HR 2.72 [2.41-3.08] P < 0.001) that allows identifying risky combinations between a given donor and a given recipient. Results were validated internally (n = 3 629) and externally in the Australia and New Zealand Liver Transplant Registry (n = 370). The current score is based on variables that are readily available at the time of graft offer. It allows identifying hazardous donor-recipient combinations in terms of risk of tumor recurrence and overall survival.

Liver transplantation for hepatocellular carcinoma after successful treatment of macrovascular invasion - a multi-center retrospective cohort study.

Macrovascular invasion is considered a contraindication to liver transplantation for hepatocellular carcinoma (HCC) due to a high risk of recurrence. The aim of the present multicenter study was to explore the outcome of HCC patients transplanted after a complete radiological regression of the vascular invasion by locoregional therapies and define sub-groups with better outcomes. Medical records of 45 patients were retrospectively reviewed, and imaging was centrally assessed by an expert liver radiologist. In the 30 patients with validated diagnosis of macrovascular invasion, overall survival was 60% at 5 years. Pretransplant alpha-fetoprotein (AFP) value was significantly different between patients with and without recurrence (P = 0.019), and the optimal AFP cutoff was 10ng/ml (area under curve = 0.78). Recurrence rate was 11% in patients with pretransplant AFP < 10ng/ml. The number of viable nodules (P = 0.008), the presence of residual HCC (P = 0.036), and satellite nodules (P = 0.001) on the explant were also significantly different between patients with and without recurrence. Selected HCC patients with radiological signs of vascular invasion could be considered for transplantation, provided that they previously underwent successful treatment of the macrovascular invasion resulting in a pretransplant AFP < 10 ng/ml. Their expected risk of post-transplant HCC recurrence is 11%, and further prospective validation is needed.

Liver Transplantation with "Hors Tour" Allocated Versus Standard MELD Allocated Grafts: Single-Center Audit and Impact on the Liver Pool in France.

BACKGROUND: The French transplant governing system defined "Rescue" (the so-called "Hors Tour") livers as those livers which were declined for the five top-listed patients. This study compares the outcomes following liver transplantation (LT) in patients who received a donor liver through a rescue allocation (RA) procedure or according to MELD score priority (standard allocation, SA) and evaluates the impact on the graft pool of a proactive policy to accept RA grafts. METHODS: Data from all consecutive patients who underwent LT with SA or RA grafts from 2011 to 2015 were compared in terms of short- and long-term outcomes. RESULTS: The 249 elective first LTs were performed with 64 (25.7%) RA and 185 (74.3%) SA grafts. RA grafts were obtained from older donors and were associated with a longer cold ischemia time. Recipients of RA livers were older and had lower MELD scores. The rates of delayed graft function, primary nonfunction, retransplantation, complications, and mortality were similar between the RA and SA groups. At 1 and 3 and 5 years, graft and patient survival rates were similar between the groups. These results were maintained after matching on recipient characteristics. Our proactive policy to accept RA grafts increased the liver pool for elective first transplantation by 25%. CONCLUSIONS: RA livers can be safely transplanted into selected recipients and significantly expand the liver pool.

Optimal oncologic management and mTOR inhibitor introduction are safe and improve survival in kidney and liver allograft recipients with de novo carcinoma.

Prognosis and oncologic treatment feasibility in solid organ transplant patients with de novo cancer remain poorly described. We investigated the impact of immunosuppressive therapy modifications after de novo cancer diagnosis on oncologic treatment feasibility, toxicities, and prognosis. Patients with de novo cancer (excluding nonmelanoma skin cancers) were selected from a monocentric cohort of 4,637 kidney and liver allograft recipients. We assessed oncologic treatment optimality according to guidelines and analyzed immunosuppressive drug modifications and oncologic treatment impacts on treatment feasibility, toxicities, and graft/patient survivals. A total of 180 patients with 205 cancers were included: mean age 60 years, median delay from transplantation to first de novo cancer 5 years. In 46% of cases, immunosuppressive therapy was modified after cancer diagnosis: 24% dose reduction and 22% mTOR inhibitor introduction. Optimal oncologic treatment was performed in 80% and 38% of patients with localized and advanced cancer respectively. Transplantation and immunosuppression hindered optimal oncologic treatment in 11% instances. Immunosuppressive therapy modifications did not affect oncologic treatment tolerance nor graft survival. In multivariate analysis, optimal oncologic treatment and mTOR inhibitor introduction improved survival of patients with de novo carcinoma. Optimal oncologic treatment is feasible in kidney and liver allograft recipients without safety concerns. Optimal oncologic treatment and mTOR inhibitor introduction seem to markedly improve survival of patients with de novo carcinoma.

Curative salvage liver transplantation in patients with cirrhosis and hepatocellular carcinoma: An intention-to-treat analysis.

The salvage liver transplantation (SLT) strategy was conceived for initially resectable and transplantable (R&T) hepatocellular carcinoma (HCC) patients, to try to obviate upfront liver transplantation, with the "safety net" of SLT in case of postresection recurrence. The SLT strategy is successful or curative when patients are recurrence free following primary resection alone, or after SLT for recurrence. The aim of the current study was to determine the SLT strategy's potential for cure in R&T HCC patients, and to identify predictors for its success. From 1994 to 2012, all R&T HCC patients with cirrhosis were enrolled in the SLT strategy. An intention-to-treat (ITT) analysis was used to determine this strategy's outcomes and predictors of success according to the above definition. In total, 110 patients were enrolled in the SLT strategy. Sixty-three patients (57%) had tumor recurrence after initial resection, and in 30 patients SLT could be performed (recurrence transplantability rate = 48%). From the time of initial resection, ITT 5-year overall and disease-free survival rates were 69% and 60%, respectively. The SLT strategy was successful in 60 patients (56%), either by resection alone (36%), or by SLT for recurrence (19%). Preresection predictors of successful SLT strategy at multivariate analysis included Model for End-Stage Liver Disease (MELD) score >10, and absence of neoadjuvant transarterial chemoembolization (TACE). Additional postresection predictive factors were absence of postresection morbidity, and T-stage 1-2 at the resection specimen. CONCLUSION: The SLT strategy is curative in only 56% of cases. Higher MELD score at inception of the strategy and no pre-resection TACE are predictors of successful SLT strategy. (Hepatology 2018;67:204-215).

Downstaging prior to liver transplantation for hepatocellular carcinoma: advisable but at the price of an increased risk of cancer recurrence - a retrospective study.

The use of downstaging prior to liver transplantation for hepatocellular carcinoma (HCC) still needs refinement. This study included patients with HCC listed for transplantation according to the Total Tumour Volume (TTV) ≤115 cm3 and alpha fetoprotein (AFP) ≤400 ng/ml criteria, with and without previous downstaging. Overall, 455 patients were listed, and 286 transplanted. Post-transplant follow-up was 38.5 ± 1.7 months. Patients downstaged to TTV115/AFP400 (n = 29) demonstrated similar disease-free survivals (DFS, 74% vs. 80% at 5 years, P = 0.949), but a trend to more recurrences (14% vs. 5.8%, P = 0.10) than those always within TTV115/AFP400 (n = 257). Similarly, patients downstaged to Milan criteria (n = 80) demonstrated similar DFS (76% vs. 86% at 5 years, P = 0.258), but more recurrences (11% vs. 1.7%, P = 0.001) than those always within Milan (n = 177). Among patients downstaged to Milan, those originally beyond TTV115/AFP400 (n = 27) had similar outcomes as those originally beyond Milan, but within TTV115/AFP400 (n = 53). However, the likelihood of being within Milan at transplant was lower for patients with more advanced original HCCs (P < 0.0001). Overall, despite an expected increase in post-transplant HCC recurrence, similar survivals can be achieved with and without downstaging, using the TTV115/AFP400 transplantation criteria, and including patients with advanced original HCCs. Downstaging should continue to be performed.

[Abdominal surgery in patients with portal hypertension†: clinical implication and management]. / Chirurgie abdominale chez les malades avec hypertension portale†: implications et prise en charge.

Abdominal surgery is sometimes needed in patients with portal hypertension. The indication may be related to the underlying liver disease, including liver resection for liver cancer and parietal surgery. Surgery may also be performed for another indication, unrelated to the liver disease. Portal hypertension increases both morbidity and mortality after abdominal surgery, and it should be taken into account when planning surgery timing and surgical strategy. This article provides an overview of the main etiologies of portal hypertension, and the post-operative outcomes after liver resection and non-hepatic abdominal surgery, underlining the importance of a multidisciplinary approach.

Une chirurgie abdominale est parfois nécessaire chez les patients atteints d'hypertension portale. Son indication peut être en lien avec une complication de la maladie du foie, comme une résection de tumeur hépatique ou une chirurgie pariétale, ou avec une affection non liée à la pathologie hépatique. L'hypertension portale augmente la morbidité et la mortalité de cette chirurgie, et l'indication ainsi que la stratégie doivent être définies avec soin. Cet article décrit les causes d'hypertension portale, les risques associés à sa présence lors d'une résection hépatique ou d'une chirurgie abdominale non hépatique. Enfin, il propose une approche multidisciplinaire, associant les chirurgiens, les hépatologues, les anatomopathologistes et les anesthésistes-réanimateurs.

[Outpatient follow-up of liver transplant recipients: the essential role of the general practitioner]. / Suivi ambulatoire du patient transplanté hépatique: le rôle essentiel du médecin généraliste.

The population of liver transplant recipients has increased in Switzerland over the last few years. Morbidity and mortality after liver transplantation are due, in the early post-transplant period, to surgical and infectious complications as well as to rejection, whereas cardiovascular, metabolic, renal and oncologic complications are the most frequent complications in the late post-transplant period. The role of the general practitioner in the long-term follow-up of liver transplant recipients is of the highest importance and can represent the first-line care of these patients as soon as 6 to 12 months post-transplantation, while maintaining a close and regular collaboration with the transplant center. Multidisciplinary and structured follow-up, along with some specific screening tests, is warranted in order to refine patient management in a timely manner and to optimize outcomes.

Les patients greffés hépatiques représentent une population croissante en Suisse. La morbidité et la mortalité après cette procédure sont liées, dans la phase précoce, aux complications chirurgicales et infectieuses ainsi que, dans une moindre mesure, au rejet, puis surviennent dans la phase tardive les complications cardiovasculaires, métaboliques, rénales et oncologiques, liées en grande partie aux traitements immunosuppresseurs. Le rôle du médecin généraliste dans le suivi médical du patient greffé hépatique est essentiel et peut être de premier recours dès 6 à 12 mois après la transplantation, tout en gardant une collaboration étroite et régulière avec le centre de transplantation. Un suivi multidisciplinaire, régulier et structuré, associé à certaines mesures de dépistage, est indispensable, afin d'adapter précocement la prise en charge et ainsi d'optimaliser le devenir des patients après la greffe.

Ligation versus no ligation of spontaneous portosystemic shunts during liver transplantation: Audit of a prospective series of 66 consecutive patients.

The management of large spontaneous portosystemic shunt (SPSS) during liver transplantation (LT) is a matter of debate. The aim of this study is to compare the short-term and longterm outcomes of SPSS ligation versus nonligation during LT, when both options are available. From 2011 to 2017, 66 patients with SPSS underwent LT: 56 without and 10 with portal vein thrombosis (PVT), all of whom underwent successful thrombectomy and could have portoportal reconstruction. The SPSS were either splenorenal (n = 40; 60.6%), left gastric (n = 16; 24.2%), or mesenterico-iliac (n = 10; 15.1%). Following portoportal anastomosis, the SPSS was ligated in 36 (54.4%) patients and left in place in 30 (45.5%) patients, based on the effect of the SPSS clamping/unclamping test on portal vein flow during the anhepatic phase. Intraoperatively, satisfactory portal flow was obtained in both groups. Primary nonfunction (PNF) and primary dysfunction (PDF) rates did not differ significantly between the 2 groups. Nonligation of SPSS was significantly associated with a higher rate of postoperative encephalopathy (P < 0.001) and major postoperative morbidity (P = 0.02). PVT occurred in 0 and 3 patients in the ligated and nonligated shunt group, respectively (P = 0.08). A composite end point, which included the relevant complications in the setting of SPSS in LT (ie, PNF and PDF, PVT, and encephalopathy) was present in 16 (44.4%) and 22 (73.3%) patients of the ligated and nonligated shunt group, respectively (P = 0.02). Patient (P = 0.05) and graft (P = 0.02) survival rates were better in the ligated shunt group. In conclusion, the present study supports routine ligation of large SPSS during LT whenever feasible.

Risk Factors for Mortality and Morbidity in Elderly Patients Presenting with Digestive Surgical Emergencies.

BACKGROUND: Emergency digestive surgery is being increasingly performed in elderly patients. The aim of the present study was to identify the predictors of mortality and morbidity following emergency digestive surgery in patients aged 80 years and older. METHODS: A single-center retrospective review was performed of consecutive patients aged ≥65 years operated for a digestive surgical emergency between January 2011 and December 2013. Two groups were compared: group A (aged 65-79 years) and group B (aged ≥80 years). RESULTS: The study population included 185 patients: 76 patients in group A and 109 in group B. The mean age was 79.9 years (65-104 years). The overall 90-day mortality rate was 23.2 and 31.9% at 1 year, which was similar between groups. The overall morbidity was 28.6%. No differences were noted between the two groups in overall, minor (Dindo I-II) or major (Dindo III-IV) morbidity rates. Multivariate analysis identified pulmonary disease (odds ratio, OR = 6.43, p = 0.02), bowel ischemia (OR = 11.41, p = 0.01), postoperative ICU stay (OR = 7.37, p < 0.0001) and the occurrence of postoperative complications (OR = 2.66, p = 0.03) as predictors of 90-day mortality. Predictors of in-hospital morbidity were preoperative hemoglobin <12 g/dL (OR = 2.49, p = 0.02) and postoperative intensive care unit (ICU) stay (OR = 6.69, p < 0.0001). An age ≥80 year was not associated with mortality or morbidity in this study. CONCLUSIONS: The decision to perform abdominal surgery in the emergency setting should be based on physiological status, which accounts for a patient's comorbidities and health status, rather than on chronological age per se.

Short-term outcomes following hepatectomy for hepatocellular carcinoma within and beyond the BCLC guidelines: A prospective study.

BACKGROUND: Western guidelines recommend resection for hepatocellular carcinoma (HCC) in so-called ideal cirrhotic patients with a Barcelona Clinic Liver Cancer (BCLC) stage 0-A tumour. This study compares short-term outcomes following resection between patients defined as ideal and nonideal according to the BCLC guidelines. METHODS: This prospective single-centre open study (ClinicalTrials.govNCT02145013) included all cirrhotic patients with HCC referred for resection from 2014 to 2016. Mortality, morbidity, unresolved liver decompensation, and readmission were measured. RESULTS: The study population included 65 consecutive patients: 32 (49%) ideal and 33 (51%) nonideal. Ideal and nonideal groups did not differ in mortality (3% vs. 6%; p = 0.57), morbidity (53% vs. 73%; p = 0.10), or unresolved liver decompensation (6% vs. 15%; p = 0.23) at 90 days. The readmission rate was higher in the nonideal (21%) than in the ideal group (3%; p = 0.02). CONCLUSION: Straying from the current guidelines for resection in a selected subset of nonideal patients doubled the number of resections performed for treating HCC, with satisfactory short-term outcomes. These results argue for the expansion of the acknowledged BCLC guidelines.

Impact of time to surgery in the outcome of patients with liver resection for BCLC 0-A stage hepatocellular carcinoma.

BACKGROUND & AIMS: The Barcelona Clinic Liver Cancer (BCLC) guidelines recommend resection for very early and early single hepatocellular carcinoma (HCC) patients. It is not known whether a delay in resection from the time of diagnosis (the time to surgery [TTS], i.e. the elapsed time from diagnosis to surgery) affects outcomes. We aim to evaluate the impact of TTS on recurrence and survival outcomes in patients with HCC. METHODS: All patients resected for BCLC stage 0-A single HCC from 2006 to 2016 were studied to evaluate the impact of TTS on recurrence rate, recurrence-free survival (RFS), transplantability following recurrence, and intention-to-treat overall survival (ITT-OS). Propensity score matching (PSM) was further performed to ensure comparability. RESULTS: The study population included 100 patients. Surgery was performed between 0.6 and 77 months after diagnosis (median TTS: three months; interquartile range: 1.8-4.6 months). There was no post-operative mortality. Compared to those with TTS <3 months, patients with TTS ≥3 months (70% of these patients had TTS 3-6 months) had a higher post-operative morbidity (36% vs. 16%, p = 0.02), a similar tumor recurrence rate (32% vs. 32%, p = 1.00), RFS (37% vs. 48%, p = 0.42), transplantability following tumor recurrence (63% vs. 50%, p = 0.48), and five-year ITT-OS (82% vs. 80%, p = 0.20). Similar results were observed after PSM. CONCLUSION: Patients with BCLC stage 0-A single HCC can undergo surgery with TTS ≥3 months without impaired oncologic outcomes. An increase in the TTS within a safe range could allow time for proper evaluation before surgery, and ethical testing of new neoadjuvant treatments, aiming to reduce the high rate of tumor recurrence despite curative resection. LAY SUMMARY: A delay of ≥3 months in time to resection after diagnosis in HCC patients meeting the European Association for the Study of Liver Disease/American Association for the Study of Liver Disease criteria for resection does not affect oncological and long-term outcomes compared to those with a delay to surgery of <3 months.

Evaluation of the current guidelines for resection of hepatocellular carcinoma using the Appraisal of Guidelines for Research and Evaluation II instrument.

BACKGROUND & AIMS: Numerous guidelines for the management of hepatocellular carcinoma (HCC) have been developed. The Appraisal of Guidelines for Research & Evaluation (AGREE II) is the only validated instrument to assess the methodological quality of guidelines. We aim to appraise the methodological quality of existing guidelines for the resection of HCC using the AGREE II instrument. METHODS: Cochrane, Medline, Google Scholar and Embase were searched using both PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria and free text. The assessment of the included clinical practice guidelines and consensuses were performed using the AGREE II instrument, version 2013. Guidelines with a score ⩾80% for the overall appraisal item were considered as applicable without modifications. RESULTS: Literature searches identified 22 clinical practice guidelines. Five out of 22 guidelines passed the 70% mark on overall assessment, 11 out of 22 had shortcomings on indications, contraindications, side effects, key recommendations, technical aspects, transparency and health economics. Ten of 22 scored below the 50% mark showing that the guideline had low methodological and overall quality. Only 3/22 clinical practice guidelines were considered applicable without modifications. CONCLUSIONS: The methodological quality of guidelines for the surgical management of HCC is generally poor. Future guideline development should be informed by the use of the AGREE II instrument. Guidelines based upon high quality evidence could improve stratification of patients and individualized treatment strategies. Lay summary: The methodology of clinical practice guidelines for resection for hepatocellular carcinoma (HCC) evaluated with the Appraisal of Guidelines for Research & Evaluation (AGREE II) instrument is generally poor. However, there are some clinical practice guidelines that are based upon higher quality evidence and can form the framework within which patients with HCC can be selected for surgical resection. Future guideline development should be informed by the use of the AGREE II instrument.

Salvage liver transplantation or repeat hepatectomy for recurrent hepatocellular carcinoma: An intent-to-treat analysis.

The salvage liver transplantation (LT) strategy was conceived for initially resectable and transplantable hepatocellular carcinoma (HCC) to obviate upfront transplantation, with salvage LT in the case of recurrence. The longterm outcomes of a second resection for recurrent HCC have improved. The aim of this study was to perform an intention-to-treat analysis of overall survival (OS) comparing these 2 strategies for initially resectable and transplantable recurrent HCC. From 1994 to 2011, 391 patients with HCC who underwent salvage LT (n = 77) or a second resection (n = 314) were analyzed. Of 77 patients in the salvage LT group, 21 presented with resectable and transplantable recurrent HCC and 18 underwent transplantation. Of 314 patients in the second resection group, 81 presented with resectable and transplantable recurrent HCC and 81 underwent a second resection. The 5-year intention-to-treat OS rates, calculated from the time of primary hepatectomy, were comparable between the 2 strategies (72% for salvage transplantation versus 77% for second resection; P = 0.57). In patients who completed the salvage LT or second resection procedure, the 5-year OS rates, calculated from the time of the second surgery, were comparable between the 2 strategies (71% versus 71%; P = 0.99). The 5-year disease-free survival (DFS) rates were 72% following transplantation and 18% following the second resection (P < 0.001). Similar results were observed after propensity score matching. In conclusion, although the 5-year OS rates were similar in the salvage LT and second resection groups, the salvage LT strategy still achieves better DFS. Second resection for recurrent HCC might be considered to be the best alternative option to LT in the current organ shortage. Liver Transplantation 23 1553-1563 2017 AASLD.
