Sequential living donor liver transplantation after liver resection optimizes outcomes for patients with high-risk hepatocellular carcinoma

BackgroundHepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality. While liver transplantation (LT) provides the best long-term survival, it is constrained by organ scarcity and strict criteria. Liver resection (LR) is often the initial treatment for patients with solitary tumors and preserved liver function. The high recurrence rates associated with LR has prompted the exploration of sequential living donor liver transplantation (seqLDLT) after LR as a strategy for HCC patients with high-risk of recurrence. MethodsWe analyzed data from 27 adult patients who underwent seqLDLT after LR for HCC at Kaohsiung Chang Gung Memorial Hospital (KCGMH) between June 1994 and December 2023. Patients were selected based on high-risk histopathological features post-LR or as part of downstaging strategy. Outcomes measured included overall survival (OS) and disease-free survival (DFS). ResultsAmong 765 HCC patients who underwent LDLT, 204 received LR before LDLT, and 27 underwent seqLDLT. Five patients (19%) underwent LDLT following LR as a downstaging strategy while the rest received seqLDLT as a preemptive strategy. The median age was 53.5 years with 85% males. Chronic hepatitis B was the predominant underlying disease (74%). The 1-, 3-, and 5-year OS and DFS rates were 100%, 96.0%, 96.0% and 100%, 96.2%, 96.2%, respectively, with two patients experiencing HCC recurrence. One patient died from HCC recurrence. High-risk histopathological features included microvascular invasion (52%), satellite nodules (15%), multiple tumors (26%), tumors > 5 cm (19%), and a total tumor diameter > 10 cm (7%). ConclusionsSeqLDLT offers a promising, tailored approach for managing HCC with adverse histopathologic features. Combining seqLDLT, downstaging strategies, and multidisciplinary treatments can achieve satisfactory OS and DFS in carefully selected patients, highlighting the need for refined criteria to identify the best candidates.

Multicenter Integration of MR Radiomics, Deep Learning, and Clinical Indicators for Predicting Hepatocellular Carcinoma Recurrence After Thermal Ablation.

To develop and validate an innovative predictive model that integrates multisequence magnetic resonance (MR) radiomics, deep learning features, and clinical indicators to accurately predict the recurrence of hepatocellular carcinoma (HCC) after thermal ablation. This retrospective multicenter cohort study enrolled patients who were diagnosed with HCC and treated via thermal ablation. We extracted radiomic features from multisequence 3T MR images, analyzed these images using a 3D convolutional neural network (3D CNN), and incorporated clinical data into the model. Model performance was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. The study included 535 patients from three hospitals, comprising 462 males and 43 females. The RDC model, which stands for the Radiomics-Deep Learning-Clinical data model, demonstrated high predictive accuracy, achieving AUCs of 0.794 in the training set, 0.777 in the validation set, and 0.787 in the test set. Statistical analysis confirmed the model's robustness and the significant contribution of the integrated features to its predictive capabilities. The RDC model effectively predicts HCC recurrence after thermal ablation by synergistically combining advanced imaging analysis and clinical parameters. This study highlights the potential of such integrative approaches to enhance prognostic assessments in HCC patients and offers a promising tool for clinical decision-making.

Transarterial Chemoembolization Combined with Microwave Ablation in Elderly Patients with Recurrent Medium or Large Hepatocellular Carcinoma.

There are insufficient data about the optimal treatment for older patients with recurring medium or large hepatocellular carcinoma (HCC). The study intended to assess the effect of transcatheter arterial chemoembolization combined with microwave ablation (TACE-MWA) in an elderly cohort through a retrospective analysis. From 2011 to 2018, a cohort of individuals (age ≥70 years) with recurrent HCC tumors ranging from 3.1 cm to 7 cm underwent either a combination treatment of TACE and MWA (n = 43) or surgical intervention (n = 33). Using the Inverse Probability of Treatment Weighting (IPTW) technique, factors of disease-free survival (DFS), overall survival (OS), and rates of major adverse events were analyzed, retrospectively. The group that underwent surgery had a greater history of alcohol use before treatment (P= 0.001), as well as a higher Barcelona Clinic Liver Cancer (BCLC) stage for the primary tumor before treatment (P= 0.014) and a higher primary tumor location before treatment (P= 0.045). The TACE-MWA group had DFS rates of 86.2%, 68.8%, and 60.4% at 1, 3, and 5 years, while the surgery group had rates of 53.0%, 42.2%, and 25.8% at the same time points. In the TACE-MWA treatment group, survival rates at 1 year, 3 years, and 5 years post-treatment were recorded as 93.0%, 80.8%, and 65.7%, respectively, while in the surgery group, they were 62.7%, 46.9%, and 42.6%. In the univariate analysis using IPTW, the type of treatment was found to have a significant correlation with disease progression (hazard ratio [HR] 0.41, 95% CI 0.20-0.86, P=0.017). IPTW multivariate analysis showed that treatment modality (HR, 0.35; 95% CI, 0.17 to 0.79; P= 0.011) was the only significant prognostic factor for OS. In elderly patients with recurrent 3.1 cm≤ HCC ≤ 7 cm, TACE-WMA was superior to surgery in the respects of DFS and OS.

Superselective ablative chemo-ethanol embolization for recurrent single hepatocellular carcinoma: a 6-month outcome analysis.

To evaluate the safety and effectiveness of superselective ablative chemo-ethanol embolization (SACE) for the treatment of patients with recurrent single hepatocellular carcinoma (rHCC). This retrospective study included 22 patients (19 men; median age, 63 years [range, 38-86]) with Child-Pugh class of A/ B/C (16/3/3) that underwent SACE between January and June 2023 for recurrent single HCCs measuring ≤5 cm in diameter using a mixture of 99% ethanol and ethiodized oil/doxorubicin emulsion. The primary endpoint was the 6-month tumor response, and the secondary endpoints were the 1-month tumor response and treatment-related safety. This study was approved by our institutional review board, and the requirement for informed consent was waived. SACE was successfully performed in 22 patients (95.2%). The complete response rates at 1-month and 6-month after treatment were 100.0% and 83.3%, respectively. At 6-month, local tumor progression occurred in one patient and intrahepatic distant metastasis was found in six patients (30.0%). No 6-month mortalities were reported. No adverse events greater than grade 2 or laboratory deteriorations were observed. Biliary complications or liver abscesses were not observed. SACE for a single rHCC was highly effective in achieving a favorable 6-month tumor response and showed acceptable adverse events. However, further prospective studies are required to verify these findings.

Lenvatinib for the Treatment of Hepatocellular Carcinoma After Liver Transplant

What Is the Issue? Liver transplant is 1 of the main curative therapies for liver cancer; however, hepatocellular carcinoma (HCC) recurrence presents in 10% to 20% of patients after liver transplant. Lenvatinib, an oral multikinase inhibitor drug, was approved for use in Canada as a first-line standard therapy for unresectable HCC, based on a pivotal trial that excluded patients who underwent a prior liver transplant. Data were scarce on the efficacy and safety of lenvatinib for treatment of HCC recurrence in patients who received a liver transplant, and were limited to a few case series and case reports. What Did We Do? We identified and summarized the literature on the evidence of the clinical effectiveness and safety of lenvatinib for the first-line treatment of patients with unresectable HCC recurrence after liver transplant. We searched key resources, including journal citation databases and conducted a focused internet search for relevant evidence published since 2019. One reviewer screened citations for inclusion based on predefined criteria, critically appraised the included studies, and narratively summarized the findings. What Did We Find? We identified a multinational, multicentre, retrospective, single-arm chart review study evaluating the efficacy and safety of lenvatinib in patients with HCC recurrence after liver transplant. Lenvatinib was primarily used as a first-line treatment for most patients (n = 42; 93.3%) and as a second-line treatment for 3 patients (6.7%). The single-arm chart review study showed lenvatinib treatment had an overall response rate (ORR) of 20.0%, a median overall survival of 14.5 months, and a median progression-free survival (PFS) of 7.6 months. These findings were similar to those randomized to lenvatinib in the pivotal phase III REFLECT trial, which excluded patients who had a prior liver transplant. What Does This Mean? The findings of this report suggest that lenvatinib has a potential role as a first-line treatment of patients with HCC recurrence after liver transplant. As the current evidence is limited to a retrospective single-arm chart review study, which had several limitations (e.g., lack of sample size calculation, noncomparative, and retrospective design), further investigations are needed to establish the clinical efficacy and safety of lenvatinib as a first-line treatment for unresectable HCC recurrence after liver transplant.

A multi-omic analysis reveals that Gamabufotalin exerts anti-hepatocellular carcinoma effects by regulating amino acid metabolism through targeting STAMBPL1

BackgroundHepatocellular carcinoma (HCC), a prevalent type of liver cancer, is characterized by an unfavorable prognosis and a high mortality rate. Identifying novel treatments to prevent HCC recurrence and metastasis remains crucial for improving patient survival. Gamabufotalin (CS-6), a primary bufadienolide derived from the traditional Chinese medicine Chansu, has demonstrated significant anti-tumor activity. However, the effects and underlying mechanisms of CS-6 on HCC cells are not yet fully understood. PurposeThis study sought to elucidate the anti-HCC effects and potential mechanisms of CS-6. In vitro experiments were conducted using the HCC cell lines MHCC97H and Huh-7, employing CCK-8 assays, colony formation assays, wound healing assays, transwell invasion and migration assays, and flow cytometry to assess apoptosis and cell cycle dynamics. A multi-omics approach, including metabolomics and RNA sequencing analysis, was utilized to identify CS-6′s molecular targets and mechanisms in HCC therapy. Additionally, in vivo assessments were performed using xenografts in nude mice. ResultsCS-6 significantly inhibited HCC cell proliferation, migration, and invasion. Multi-omics analysis suggested that CS-6′s anti-HCC effects may involve the modulation of metabolic pathways, potentially through the downregulation of STAMBPL1, resulting in reduced mTOR signaling, increased apoptosis, and suppression of malignant HCC behavior. In vivo studies further confirmed that CS-6 significantly suppressed tumor growth and enhanced apoptosis and autophagy within tumors. ConclusionThese results underscore the therapeutic potential of CS-6 in HCC treatment. The study offers novel insights into the mechanism of CS-6, suggesting that its therapeutic efficacy may be uniquely mediated by targeting STAMBPL1. This distinct mechanism sets CS-6 apart from existing HCC treatments and positions it as a promising candidate for further clinical investigation.

Validation of the R3-AFP model for risk prediction of HCC recurrence after liver transplantation in the SiLVER randomized clinical trial.

Explant-based models for assessing HCC recurrence after liver transplantation serve as the gold standard, guiding post-liver transplantation screening and immunosuppression adjustment. Incorporating alpha-fetoprotein (AFP) levels into these models, such as the novel R3-AFP score, has notably enhanced risk stratification. However, validation of these models in high-evidence data is mandatory. Therefore, the aim of the present research was to validate the R3-AFP score in a randomized clinical trial. We analyzed the intention-to-treat population from the 2-arm SiLVER trial (NCT00355862), comparing calcineurin-based ([calcineurin inhibitors]-Group A) versus mammalian target of rapamycin inhibitors-based (sirolimus-Group B) immunosuppression for post-liver transplantation HCC recurrence. Competing risk analysis estimated sub-hazard ratios, with testing of discriminant function and calibration. Overall, 508 patients from the intention-to-treat analysis were included (Group A, n = 256; Group B, n = 252). The R3-AFP score distribution was as follows: 42.6% low-risk (n = 216), 35.7% intermediate-risk (n = 181), 19.5% high-risk (n = 99), and 2.2% very-high-risk (n = 11) groups. The R3-AFP score effectively stratified HCC recurrence risk, with increasing risk for each stratum. Calibration of the R3-AFP model significantly outperformed other explant-based models (Milan, Up-to-7, and RETREAT), whereas discrimination power (0.75 [95% CI: 0.69; 0.81]) surpassed these models, except for the RETREAT model ( p = 0.49). Subgroup analysis showed lower discrimination power in the mammalian target of rapamycin group versus the calcineurin inhibitors group ( p = 0.048). In conclusion, the R3-AFP score accurately predicted HCC recurrence using high-quality evidence-based data, exhibiting reduced performance under mammalian target of rapamycin immunosuppression. This highlights the need for further research to evaluate surveillance schedules and adjuvant regimens.

Spatial analysis reveals targetable macrophage-mediated mechanisms of immune evasion in hepatocellular carcinoma minimal residual disease.

Hepatocellular carcinoma (HCC) frequently recurs from minimal residual disease (MRD), which persists after therapy. Here, we identified mechanisms of persistence of residual tumor cells using post-chemoembolization human HCC (n = 108 patients, 1.07 million cells) and a transgenic mouse model of MRD. Through single-cell high-plex cytometric imaging, we identified a spatial neighborhood within which PD-L1 + M2-like macrophages interact with stem-like tumor cells, correlating with CD8+ T cell exhaustion and poor survival. Further, through spatial transcriptomics of residual HCC, we showed that macrophage-derived TGFβ1 mediates the persistence of stem-like tumor cells. Last, we demonstrate that combined blockade of Pdl1 and Tgfβ excluded immunosuppressive macrophages, recruited activated CD8+ T cells and eliminated residual stem-like tumor cells in two mouse models: a transgenic model of MRD and a syngeneic orthotopic model of doxorubicin-resistant HCC. Thus, our spatial analyses reveal that PD-L1+ macrophages sustain MRD by activating the TGFβ pathway in stem-like cancer cells and targeting this interaction may prevent HCC recurrence from MRD.

SIMAP500: A novel risk score to identify recipients at higher risk of hepatocellular carcinoma recurrence following liver transplantation.

Recurrence of hepatocellular carcinoma (HCC) following liver transplantation (LT) has a devastating influence on recipients' survival; however, the risk of recurrence is not routinely stratified. Risk stratification is vital with a long LT waiting time, as that could influence the recurrence despite strict listing criteria. This study aims to identify predictors of recurrence and develop a novel risk prediction score to forecast HCC recurrence following LT. A retrospective review of LT for HCC recipients at University Hospitals Birmingham between July 2011 and February 2020. Univariate and multivariate analyses were performed to identify recurrence predictors, based on which the novel SIMAP500 (satellite nodules, increase in size, microvascular invasion, AFP > 500, poor differentiation) risk score was proposed. 234 LTs for HCC were performed with a median follow-up of 5.3 years. Recurrence developed in 25 patients (10.7%). On univariate analyses, RETREAT score > 3, α-fetoprotein (AFP) at listing 100-500 and > 500, bridging, increased tumour size between imaging at the listing time and explant histology, increase in the size of viable tumour between listing and explant, presence of satellite nodules, micro- and macrovascular invasion on explant and poor differentiation of tumours were significantly associated with recurrence, based on which, the SIMAP500 risk score is proposed. The SIMAP500 demonstrated an excellent predictive ability (c-index = 0.803) and outperformed the RETREAT score (c-index = 0.73). SIMAP500 is indicative of the time to disease recurrence. SIMAP500 risk score identifies the LT recipients at risk of HCC recurrence. Risk stratification allows patient-centric post-transplant surveillance programs. Further validation of the score is recommended.

Challenges related to clinical decision-making in hepatocellular carcinoma recurrence post-liver transplantation: Is there a hope?

Hepatocellular carcinoma (HCC) is a common liver malignancy and represents a serious cause of cancer-related mortality and morbidity. One of the favourable curative surgical therapeutic options for HCC is liver transplantation (LT) in selected patients fulfilling the known standard Milan/University of California San Francisco criteria which have shown better outcomes and longer-term survival. Despite careful adherence to the strict HCC selection criteria for LT in different transplant centres, the recurrence rate still occurs which could negatively affect HCC patients' survival. Hence HCC recurrence post-LT could predict patients' survival and prognosis, depending on the exact timing of recurrence after LT (early or late), and whether intra/extrahepatic HCC recurrence. Several factors may aid in such a complication, particularly tumour-related criteria including larger sizes, higher grades or poor tumour differentiation, microvascular invasion, and elevated serum alpha-fetoprotein. Therefore, managing such cases is challenging, different therapeutic options have been proposed, including curative surgical and ablative treatments that have shown better outcomes, compared to the palliative locoregional and systemic therapies, which may be helpful in those with unresectable tumour burden. To handle all these issues in our review.

Assessing microvascular invasion in HBV-related hepatocellular carcinoma: an online interactive nomogram integrating inflammatory markers, radiomics, and convolutional neural networks.

The early recurrence of hepatocellular carcinoma (HCC) correlates with decreased overall survival. Microvascular invasion (MVI) stands out as a prominent hazard influencing post-resection survival status and metastasis in patients with HBV-related HCC. The study focused on developing a web-based nomogram for preoperative prediction of MVI in HBV-HCC. 173 HBV-HCC patients from 2017 to 2022 with complete preoperative clinical data and Gadopentetate dimeglumine-enhanced magnetic resonance images were randomly divided into two groups for the purpose of model training and validation, using a ratio of 7:3. MRI signatures were extracted by pyradiomics and the deep neural network, 3D ResNet. Clinical factors, blood-cell-inflammation markers, and MRI signatures selected by LASSO were incorporated into the predictive nomogram. The evaluation of the predictive accuracy involved assessing the area under the receiver operating characteristic (ROC) curve (AUC), the concordance index (C-index), along with analyses of calibration and decision curves. Inflammation marker, neutrophil-to-lymphocyte ratio (NLR), was positively correlated with independent MRI radiomics risk factors for MVI. The performance of prediction model combined serum AFP, AST, NLR, 15 radiomics features and 7 deep features was better than clinical and radiomics models. The combined model achieved C-index values of 0.926 and 0.917, with AUCs of 0.911 and 0.907, respectively. NLR showed a positive correlation with MRI radiomics and deep learning features. The nomogram, incorporating NLR and MRI features, accurately predicted individualized MVI risk preoperatively.

Robot-assisted laparoscopic hepatectomy for hepatocellular carcinoma with Fontan-associated liver disease: a world-first case report

BackgroundFontan-associated liver disease (FALD) encompasses hepatic complications following the Fontan procedure, ranging from fibrosis to hepatocellular carcinoma (HCC). Despite advancements in surgical techniques and perioperative care, robot-assisted laparoscopic hepatectomy (RALH) for HCC in patients with FALD has not been previously reported owing to concerns about the Fontan circulation.Case presentationWe present the first case of RALH for recurrent HCC in a 45-year-old man after the Fontan procedure. The preoperative evaluation confirmed good cardiac function. The procedure involved meticulous monitoring and management of central venous pressure and was successfully completed with minimal blood loss. Postoperative recovery was uneventful. With thorough preoperative cardiac assessment and close collaboration between cardiologists and anesthesiologists, RALH can be safely performed in selected patients with FALD.ConclusionsEven if a patient has a history of FALD, RALH can be safely performed in selected patients under appropriate conditions.

Recurrence of Hepatocellular Carcinoma after Liver Transplantation: Clinical Patterns and Hierarchy of Salvage Treatments

Introduction: The multiparametric nature of recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) still leads to uncertainty with its practical management. This study aims to characterize the main posttransplant recurrence patterns of HCC and to explore the therapeutic modalities targeting recurrence. Methods: Consecutive patients who underwent LT for HCC at a single tertiary center were analyzed. The time from first recurrence to death was investigated for each site of presentation. The impact of each recurrence-targeted treatment on survival was studied. Results: Of 660 patients with HCC, any recurrence occurred in 96 (15.4%) patients with a median time to recurrence of 20.0 months (95% CI: 15.6–23.8). Patients recurred across different patters including solitary distant locations (30.8%, n = 28), liver only (24.2%, n = 22), lung (18.7%, n = 17), multi-organ disease (17.6%, n = 16), and bone (8.8%, n = 8). Multi-organ and bone recurrences had the poorest survival, while solitary distant lesions and pulmonary recurrences had the best outcomes. Each treatment modality carried a distinctive survival. Conclusions: Patients recurred across 3 patterns with different prognostic implications. The benefit of each treatment option on distinct recurrence patterns appears to be influenced by the biological behavior inherent in the recurrence pattern itself.

Liver resection for hepatocellular carcinoma in elderly patients: does age matter?

BackgroundEvaluation of the influence of the age of the patients upon the outcomes of liver resection (LR) for hepatocellular carcinoma (HCC).MethodsHCC patients who underwent LR between 2010 and 2020 were analyzed. They were divided into 3 groups depending on the patient’s age. Group I (patients less than 60 years), Group II (patients between 60 and 69 years), and Group III (patients equal to or more than 70 years).Results364 patients were included. A significantly higher serum bilirubin and alpha feto-protein were noted in Group I and serum creatinine was noted in Group III. The study groups did not show any significant differences regarding HCC site, number, macrovascular invasion, the extent of LR, Pringle maneuver, and perioperative blood transfusions. Longer operation time was found in Groups II and III, while more blood loss was noted in Group (I) Group I patients had longer hospital stays. Higher postoperative morbidities were noted in both Group I and Group (II) Higher incidence of post-hepatectomy liver dysfunction was noted in Group I. More early mortalities were found in Group I, related to liver failure. We did not experience early mortality in Group (III) Late Mortalities occurred in 117 patients (32.1%). HCC recurrence occurred in 165 patients (45.3%). Regarding the overall- and tumor-free survival, we did not experience any significant differences among the 3 groups (Log Rank: p = 0.371 and 0.464 respectively).ConclusionsCurative LR can be safely performed in selected elderly patients with HCC. An advanced patient’s age should not be considered as a contraindication for curative LR.

Hepatocellular Carcinoma (HCC) Metastasis to the Diaphragm Muscle: A Systematic Review and Meta-Analysis of Case Reports.

The purpose of this study was to conduct a systematic review and meta-analysis of case reports presenting HCC spread to the diaphragm muscle and to determine possible risk factors for this condition. An extensive literature search was performed using the following electronic databases: MEDLINE, CINAHL, ScienceDirect, Google Scholar, and DOAJ. A total of 18 articles describing 27 hepatocellular carcinoma patients were included in this review. The presence of HCC cells in the superior liver segment is strongly associated with metastases to the diaphragm. Among the two types of diaphragm involvement by HCC cells, diaphragm infiltration occurs much more frequently than diaphragm adhesion. However, an HCC nodule in the 8th liver segment and a higher number of liver segments involved by HCC cells predispose patients to diaphragm adhesion. Hepatitis B is a risk factor for diaphragm metastases in recurrent HCC. The tumor diameter is not associated with HCC spread to the diaphragm muscle. We did not find specific symptoms reported by patients that could indicate HCC metastasis to the diaphragm muscle. The presence of hepatitis B and the localization of HCC cells in superior liver segments, especially in the 8th liver segment, should be take into consideration in the diagnostic process.

Challenges in Liver Transplantation for Hepatocellular Carcinoma: A Review of Current Controversies.

Liver transplantation (LT) remains one of the most effective treatments for hepatocellular carcinoma (HCC) and significantly enhances patient survival. However, the application of LT for HCC faces challenges owing to advancements in cancer-specific treatment modalities and the increased burden of patients' comorbidities. This narrative review explores current controversies and advancements in LT for HCC. Key areas of focus include the management of comorbidities and patient education by advanced practice nurses, impacts of frailty on waitlists and post-LT outcomes, selection criteria for LT in the era of new downstaging tools, role of radiology in patient selection, and implications of potential immunotherapy use both before and after LT. Additionally, the importance of immunosuppression management with strategies aimed at minimizing rejection while considering the risk of HCC recurrence and the role of surveillance for HCC recurrence is highlighted. This review also underscores the importance of a multidisciplinary approach for optimizing outcomes in patients with HCC undergoing LT.

A nomogram model for early recurrence of HBV-related hepatocellular carcinomas after radical hepatectomy.

To identify the risk factors and construct a predictive model for early recurrence of hepatitis B virus(HBV-)- related hepatocellular carcinomas(HCCs) after radical resection. A total of 465 HBV-related HCC patients underwent radical resections between January 1, 2012 and August 31, 2018.Their data were collected through the inpatient information management system of the First Affiliated Hospital of University of Science and Technology of China. Survival and subgroup analyses of early recurrence among male and female patients were performed using Kaplan-Meier curves. The independent risk factors associated with early postoperative tumor recurrence were analyzed using multivariate Cox proportional hazards regression model. Based on these independent risk factors, a risk function model for early recurrence was fitted, and a column chart for the prediction model was drawn for internal and external validation. A total of 181 patients developed early recurrences, including 156 males and 25 females. There was no difference in the early recurrence rates between males and females. Tumor diameters>5cm, microvascular invasion and albumin level<35 g/L were independent risk factors for early recurrence. A nomogram for the early recurrence prediction model was drawn; the areas under the curve for the model and for external verification were 0.638 and 0.655, respectively. Tumor diameter>5 cm, microvascular invasion, and albumin level<35 g/L were independent risk factors for early recurrence. The prediction model based on three clinical indicators could predict early recurrence, with good discrimination, calibration, and extrapolation.
