Hcc surveillance post liver transplant

Prediction of hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT) with knowledge of explant data is important for guiding post-LT surveillance and treatment. The RETREAT score was recently introduced for this purpose, but has not been validated outside the USA. In a retrospective single-center study of 169 consecutive patients undergoing LT in Gothenburg, through 2000-2017 (mean age 57 years, 80% men), there were 34 HCC recurrences during a median 4.6-year follow-up. The 5-year cumulative incidence of HCC recurrence was 0% with RETREAT scores of 0-1 (18%), 11-22% with scores of 2-4 (58%), and 65% with scores of 5-8 (24%)...

Background: This study aimed to evaluate the role of plasma microRNA panel (miR-122, miR-192, miR-21, miR-223, miR-26a, miR-27a and miR-801) for prediction and surveillance of early tumor recurrence in hepatocellular carcinoma (HCC) patients who had undergone liver transplantation (LT). Methods: The expression of plasma microRNA panel was assayed in 193 HCC patients (training cohort, n =151; validation cohort, n = 42). Sensitivity and specificity for detecting post-transplant HCC recurrence, and the relationship of microRNA panel expression with clinical characteristics were analyzed accordingly...

BACKGROUND: The Risk Estimation of Tumor Recurrence After Transplant (RETREAT) score as a prognostic index for recurrence has been reported previously and has not been validated outside the USA. Our study has validated the score in a single center UK cohort of patients being transplanted for HCC. METHODS: LT for HCC between 2008 and 2018 at our center were analyzed. Recurrence-free survival (RFS) was compared by the RETREAT score and validated using Net Reclassification Improvement (NRI) by comparing it to Milan criteria...

Recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT), occurring in 10-15% of cases, is a major concern. A lot of work has been done in order to refine the selection of LT candidates with HCC and to improve the outcome of patients with recurrence. Despite this, the prognosis of these patients remains poor, partly due to the several areas of uncertainty in their management. Even if surveillance for HCC recurrence is crucial for early detection, there is currently no evidence to support a specific and cost-effective post-LT surveillance strategy...

The biomarkers α-fetoprotein (AFP), Lens culinaris agglutinin-reactive AFP fraction (AFP-L3), and des-γ-carboxy prothrombin (DCP) have emerging implications in hepatocellular carcinoma (HCC) surveillance, overall prognosis, and post-surgical recurrence risk. This retrospective study investigated treatment and bridge to liver transplant (LT) prognosis associated with AFP, AFP-L3%, and DCP biomarker profiles prior to liver-directed therapy (LDT). In a 140-patient cohort, each biomarker was associated with HCC progression risk using the established thresholds of AFP > 20 ng/mL, AFP-L3 > 15%, and DCP > 7...

The annual incidence of hepatocellular carcinoma (HCC) continues to rise. Over the last two decades, liver transplantation (LT) has become the preferable treatment of HCC, when feasible and strict selection criteria are met. With the rise in HCC-related LT, compounded by downstaging techniques and expansion of transplant selection criteria, a parallel increase in number of post-transplantation HCC recurrence is expected. Additionally, in the context of an immunosuppressed transplant host, recurrences may behave aggressively and more challenging to manage, resulting in poor prognosis...

BACKGROUND: HIV-infected patients now have long life expectation since the introduction of the highly active antiretroviral therapy (HAART). Liver diseases, especially cirrhosis and hepatocellular carcinoma (HCC), currently represent a leading cause of death in this setting of patients. AIM: To address the results of liver transplantation (LT) for HCC in HIV-infected patients. METHODS: All patients with and without HIV infection who underwent LT for HCC (n = 420) between 2001 and 2021 in our center were analyzed with the intent of comparing graft and patient survival...

Precise staging is essential in the management of patients with recurrent hepatocellular carcinoma (HCC) after liver transplantation. There is no current consensus on the optimal staging strategy. We conducted this study to evaluate the performance of dual-tracer positron emission tomography-computed tomography (PET-CT) for this purpose and to investigate whether the results of dual-tracer PET-CT affected patient management. Methods: A retrospective study was conducted. Patients who underwent dual-tracer PET-CT for suspected or confirmed HCC recurrence after liver transplant were included...

BACKGROUND: The impact of incidentally detected hepatocellular carcinoma (iHCC) in explanted liver on the prognosis of the patients undergoing orthotopic liver transplantation remains controversial with several studies reporting survival worse than true non-hepatocellular carcinoma (non-HCC) recipients. Patients undergoing living donor liver transplantation (LDLT) have the benefit of a shorter waiting time to transplant which in principle should reduce the frequency of new tumors developing while waiting for transplant...

BACKGROUND & AIMS: Gastrointestinal (GI) malignancies are common after liver transplantation. The aim of this study was to identify the risk and timing of the more common GI malignancies, colorectal and pancreatic cancer, to aid in optimizing potential post-transplant screening practices. METHODS: Data from the United Network for Organ Sharing database of all adult liver transplant recipients from 1997 and 2017 was analyzed and comparison made with cancer incidence from general population data using Surveillance, Epidemiology, and End Results data...

Recurrence of hepatocellular carcinoma (HCC) is an important predictor of survival after liver transplantation (LT). Recent studies show that early diagnosis, aggressive treatment, and surveillance may improve outcomes after HCC recurrence. We sought to determine the current practices and policies regarding surveillance for HCC recurrence after LT. Methods: We conducted a web-based national survey of adult liver transplant centers in the United States to capture center-specific details of HCC surveillance post-LT...

The incidence of hepatocellular carcinoma (HCC) is growing in the US, especially among the elderly. Older patients are increasingly getting transplanted for HCC, but the impact of advancing age on long-term post-transplant outcomes is not clear. To study this, we used data from the US Multicenter HCC Transplant Consortium (UMHTC) of 4980 patients. We divided the patients into 4 groups by age at transplantation- 18-64 (n = 4001), 65-69 (n = 683), 70-74 (n = 252) and ≥ 75 years (n = 44). There were no differences in HCC tumor stage, type of bridging locoregional therapy or explant residual tumor between the groups...

BACKGROUND & AIMS: Liver transplantation (LTx) is one of the most effective treatments for hepatocellular carcinoma (HCC); however, tumor recurrence after LTx often leads to poor outcomes. This study investigated the value of circulating tumor cells (CTCs) as a predictor of recurrence following LTx in patients with HCC. METHODS: This analysis included 193 patients with HCC who underwent LTx at our institute and accepted pre- and post-operative CTC detection; 38 were selected for serial CTC monitoring...

INTRODUCTION: Hepatocellular carcinoma (HCC) is an increasingly common disease with liver transplant (LT) the best long-term therapy for early stage disease. We will review the data for assessing risk and managing recurrence for patients undergoing LT for HCC. AREAS COVERED: In this review, we will provide an overview of methods of patient risk stratification in the post-transplant period, the data around surveillance for HCC recurrence, and the evidence for and against post-LT adjuvant treatment strategies...

AIM: The direct acting antivirals (DAAs) for HCV, has reduced the decompensation risk. Immunosuppressants for transplantation raise the risk of occurrence of de novo malignancies. We assessed the probabilities of and risk factors for de novo HCC developing post-living donor liver transplantation (LDLT). METHODS: We retrospectively evaluated the data of developed HCC in a graft including metastatic HCC post-LDLT from the 2,779 adult cases collected from nine major LT centers in Japan...

BACKGROUND/AIMS: Hepatocellular carcinoma (HCC) is a leading indication for liver transplantation (LT) worldwide. Early identification of patients at risk for HCC recurrence is of paramount importance since early treatment of recurrent HCC after LT may be associated with increased survival. We evaluated incidence of and predictors for HCC recurrence, with a focus on the course of AFP levels. METHODS: We performed a retrospective, single-center study of 99 HCC patients who underwent LT between January 28th, 1997 and May 11th, 2016...

BACKGROUND: Currently, no surveillance guidelines for hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT) exist. In this retrospective, multicenter study, we have investigated the role of surveillance imaging on postrecurrence outcomes. METHODS: Patients with recurrent HCC after LT from 2002-2016 were reviewed from 3 transplant centers (UCSF, Mayo Clinic Florida, and University of Toronto). For this study, we proposed the term cumulative exposure to surveillance (CETS) as a way to define the cumulative sum of all the protected intervals that each surveillance test provides...

Hepatocellular carcinoma (HCC) is an increasingly common indication for liver transplantation (LT) in the United States and in many parts of the world. In the last decade, significant work has been done to better understand how to risk stratify LT candidates for recurrence of HCC following transplant using a combination of biomarker and imaging findings. However, despite the high frequency of HCC in the LT population, guidance regarding posttransplant management is lacking. In particular, there is no current evidence to support specific post-LT surveillance strategies, leading to significant heterogeneity in practices...

Single hepatocellular carcinoma (HCC) tumors can be successfully eradicated with thermal ablation (TA). We assessed the validity of the Liver Imaging Reporting and Data System Treatment Response (LR-TR) criteria with a retrospective analysis of a single-center database of patients with small HCC tumors (<3 cm in diameter) who underwent both laparoscopic TA and liver transplantation (LT) from 2004 to 2018. Postablation MRIs were assigned LR-TR categories (nonviable, equivocal, and viable) for ablated lesions and Liver Imaging Reporting and Data System (LI-RADS) categories (probable or definite HCC) for untreated lesions...

BACKGROUND: Liver transplantation (LT) is regarded as the best treatment for both primary and recurrent hepatocellular carcinoma (HCC). Post-transplant HCC recurrence rate is relatively low but significant, ranging from 10%-30% according to different series. When recurrence happens, it is usually extrahepatic and associated with poor prognosis. A predictive model that allows patient stratification according to recurrence risk can help to individualize post-transplant surveillance protocol and guidance of the use of anti-tumor immunosuppressive agents...
