AI-Safe-C Score: Assessing Liver-Related Event Risks in Non-Cirrhotic Patients after Successful Direct-Acting Antiviral Treatment.

BACKGROUND & AIMS: Direct-acting antivirals (DAAs) have considerably improved chronic hepatitis C (HCV) treatment; however, post-sustained virological response (SVR) follow-up typically neglects the risk of liver-related events (LREs). This study introduces and validates artificial intelligence-safe score (AI-Safe-C score) to assess the risk of LREs in non-cirrhotic patients after successful DAA treatment. METHODS: The random survival forest model was trained to predict LREs in 913 non-cirrhotic HCV patients after SVR in Korea and was further tested in a combined cohort from Hong Kong and France (N = 1264). The model's performance was assessed using Harrell's C-index and the area under the time-dependent receiver operating characteristic curve (AUROC). RESULTS: The AI-Safe-C score, which incorporated liver stiffness measurement (LSM), age, sex, and six other biochemical tests-with LSM being ranked as the most important among 9 clinical features-demonstrated a C-index of 0.86 (95% confidence interval [CI]: 0.82-0.90) in predicting LREs in an external validation cohort. It achieved 3- and 5-year LRE AUROCs of 0.88 (95%CI, 0.84-0.92) and 0.79 (95%CI, 0.71-0.87), respectively, and for hepatocellular carcinoma, a C-index of 0.87 (95%CI, 0.81-0.92) with 3- and 5-year AUROCs of 0.88 (95%CI, 0.84-0.93) and 0.82 (95%CI, 0.75-0.90), respectively. Using a cut-off of 0.7, the 5-year LRE rate within a high-risk group was between 3.2% and 6.2%, mirroring the incidence observed in individuals with advanced fibrosis, in stark contrast to the significantly lower incidence of 0.2% to 0.6% in a low-risk group. CONCLUSION: AI-Safe-C score is a useful tool for identifying patients without cirrhosis who are at higher risk of developing LREs. The post-SVR LSM, as integrated within the AI-Safe-C score, plays a critical role in predicting future LREs. IMPACT AND IMPLICATIONS: The AI-Safe-C score introduces a paradigm shift in the management of non-cirrhotic patients post-DAA treatment, a cohort traditionally not included in routine surveillance protocols for LREs. By accurately identifying a subgroup at a comparably high risk of LREs, akin to those with advanced fibrosis, this predictive model facilitates a strategic reallocation of surveillance and clinical resources.

Hepatocellular carcinoma in cirrhotic versus non-cirrhotic liver: Treatment and survival differences in a nationwide cohort.

BACKGROUND AND AIMS: Numerous studies have reported superior outcome for patients with hepatocellular carcinoma (HCC) in non-cirrhotic compared to cirrhotic livers. This cohort study aims to describe the clinical presentation, disease course, treatment approaches, and survival differences in a population-based setting. METHODS: Data on patients diagnosed with HCC in Sweden between 2008 and 2018 were identified and extracted from the Swedish Liver registry (SweLiv). Descriptive and survival statistics were applied. RESULTS: Among the 4259 identified patients, 34% had HCC in a non-cirrhotic liver. Cirrhotic patients presented at a younger age (median = 64 vs 74 years, p < 0.001) and with a poorer performance status (Eastern Cooperative Oncology Group (ECOG) = 0-1: 64% vs 69%, p = 0.024). Underlying liver disease was more prevalent among cirrhotic patients (81% vs 19%, p < 0.001). Tumors in non-cirrhotic livers were diagnosed at a more advanced stage (T3-T4: 46% vs 31%) and more frequently with metastatic disease at diagnosis (22% vs 10%, p < 0.001). Tumors were significantly larger in non-cirrhotic livers (median size of largest tumor 7.5 cm) compared to cirrhotic livers (3.5 cm) (p < 0.001). Curative interventions were more commonly intended (45% vs 37%, p < 0.001) and performed (40% vs 31%, p < 0.001) in the cirrhotic vs non-cirrhotic patients. Median survival was 19 months (95% confidence interval (CI) = 18-21 months), in patients with cirrhosis as compared to 13 months in non-cirrhotic patients (95% CI = 11-15) (p < 0.001). In the multivariable Cox regression model, cirrhosis was not an independent predictor of survival, neither among curatively nor palliatively treated patients. CONCLUSION: These population-based data show that patients with HCC in a cirrhotic liver receive curative treatment to a greater extent and benefit from superior survival compared to those with HCC in a non-cirrhotic liver. The differences in survival are more attributable to patient and tumor characteristics rather than the cirrhotic status itself. CLINICAL TRIAL REGISTRATION: not applicable.

Sarcopenia negatively affects postoperative short-term outcomes of patients with non-cirrhosis liver cancer.

BACKGROUND: Literature review have shown that sarcopenia substantially alters the postoperative outcomes after liver resection for malignant tumors. However, these retrospective studies do not distinguish cirrhotic and non-cirrhotic liver cancer patients, nor combine the assessment of muscle strength in addition to muscle mass. The purpose of this study is to study the relationship between sarcopenia and short-term outcomes after hepatectomy in patients with non-cirrhotic liver cancer. METHODS: From December 2020 to October 2021, 431 consecutive inpatients were prospectively enrolled in this study. Muscle strength and mass were assessed by handgrip strength and the skeletal muscle index (SMI) on preoperative computed tomographic scans, respectively. Based on the SMI and the handgrip strength, patients were divided into four groups: group A (low muscle mass and strength), group B (low muscle mass and normal muscle strength), group C (low muscle strength and normal muscle mass), and group D (normal muscle mass and strength). The main outcome was major complications and the secondary outcome was 90-d Readmission rate. RESULTS: After strictly exclusion, 171 non-cirrhosis patients (median age, 59.00 [IQR, 50.00-67.00] years; 72 females [42.1%]) were selected in the final analysis. Patients in group A had a statistically significantly higher incidence of major postoperative complications (Clavien-Dindo classification ≥ III) (26.1%, p = 0.032), blood transfusion rate (65.2%, p < 0.001), 90-day readmission rate (21.7%, p = 0.037) and hospitalization expenses (60,842.00 [IQR, 35,563.10-87,575.30], p < 0.001) than other groups. Sarcopenia (hazard ratio, 4.21; 95% CI, 1.44-9.48; p = 0.025) and open approach (hazard ratio, 2.56; 95% CI, 1.01-6.49; p = 0.004) were independent risk factors associated with major postoperative complications. CONCLUSIONS: Sarcopenia is closely related to poor short-term postoperative outcomes in non-cirrhosis liver cancer patients and the assessment that combines muscle strength and muscle mass can simply and comprehensively identify it.

An Overview of Hepatocellular Carcinoma Surveillance Focusing on Non-Cirrhotic NAFLD Patients: A Challenge for Physicians.

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease worldwide and it ranges from simple steatosis to hepatocellular carcinoma (HCC). HCC represents the first liver tumor and the third source of cancer death. In the next few years, the prevalence of NAFLD and consequently of HCC is estimated to increase, becoming a major public health problem. The NAFLD-HCC shows several differences compared to other causes of chronic liver disease (CLD), including the higher percentage of patients that develop HCC in the absence of liver cirrhosis. In HCC surveillance, the international guidelines suggest a six months abdominal ultrasound (US), with or without alpha-fetoprotein (AFP) evaluation, in patients with cirrhosis and in a subgroup of patients with chronic hepatitis B infection. However, this screening program reveals several limitations, especially in NAFLD patients. Thus, new biomarkers and scores have been proposed to overcome the limits of HCC surveillance. In this narrative review we aimed to explore the differences in the HCC features between NAFLD and non-NAFLD patients, and those between NAFLD-HCC developed in the cirrhotic and non-cirrhotic liver. Finally, we focused on the limits of tumor surveillance in NAFLD patients, and we explored the new biomarkers for the early diagnosis of HCC.

High-throughput circular RNA sequencing reveals the profiles of circular RNA in non-cirrhotic hepatocellular carcinoma.

BACKGROUND: Liver cirrhosis is a well-known risk factor for hepatocellular carcinoma (HCC). However, some HCC cases can also originate from non-cirrhotic livers. The aim of this study was to identify key circular RNAs (circRNAs) associated with the tumorigenesis of non-cirrhotic liver disease. METHODS: The differently expressed circRNAs between non-cirrhotic and cirrhotic HCCs were assessed with use of high-throughput circRNAs sequencing and validated with quantitative reverse transcription polymerase chain reaction (qRT-PCR). Potential biological functions of these dysregulated circRNAs were predicted with use of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. A circRNA-miRNA-mRNA regulation network was constructed as achieved with use of miRanda software and visualized using Cytoscape software. Biological functions of the four most prominent dysregulated circRNAs identified were confirmed by in vitro experiments. Moreover, possible translations of these dysregulated circRNAs were also predicted. RESULTS: A total of 393 dysregulated circRNAs were identified between non-cirrhotic and cirrhotic HCC, including 213 that were significantly up-regulated and 180 significantly down-regulated circRNAs. Expression levels of the six most prominent dysregulated circRNAs were further validated using qRT-PCR. Many tumor related miRNAs were involved in the circRNA-miRNA-mRNA networks, including miR-182-5p, miR-561-3p, miR-125a-5p, miR-145, miR-23b-3p and miR-30e-3p, and downstream mRNAs of dysregulated circRNAs were significantly related with biological processes involved in the progression of tumors, including proliferation, migration, differentiation, and focal adhesion. Results from the in vitro experiments demonstrated that the most prominent dysregulated circRNAs exerted notable effects upon the proliferation and migration of HCC cells. Finally, we also identified 19 dysregulated circRNAs having potential for the coding of functional peptides. CONCLUSION: The results of this present study indicate that circRNAs may play important roles in tumorigenesis of non-cirrhotic HCC. Such findings provide some novel insights and pave the way for the development of future studies directed at investigating the initiation and treatment of HCC.

Epidemiology of non-alcoholic fatty liver disease and hepatocellular carcinoma.

The prevalence of hepatocellular carcinoma (HCC) is increasing worldwide, whereas that of most other cancers is decreasing. Non-alcoholic fatty liver disease (NAFLD), which has increased with the epidemics of obesity and type 2 diabetes, increases the risk of HCC. Interestingly, NAFLD-associated HCC can develop in patients with or without cirrhosis. A lack of awareness about NAFLD-related HCC has led to delays in diagnosis. Therefore, a large number of patients with HCC are diagnosed with advanced-stage HCC with low 5-year survival. In this context, increasing awareness of NAFLD and NAFLD-related HCC may lead to earlier diagnosis and more effective interventions.

[Progress in the diagnosis and treatment of idiopathic non-cirrhotic portal hypertension].

Idiopathic non-cirrhotic portal hypertension is a rare group of clinical syndromes characterized by clinical manifestations of portal hypertension in the absence of histological manifestations of liver cirrhosis, and with the exclusion of known intrahepatic and extrahepatic causes of portal hypertension. Importantly, its etiology and pathogenesis are unclear, but it has been determined to be related to the development of intrahepatic vascular disease. It is currently believed that possible pathogenic mechanisms include immune disorders, chronic infections, drug-related poisoning or injury, microthrombosis, genetic abnormalities, etc. The most common clinical manifestations are esophagogastric varices and splenomegaly. Ascites and hepatic encephalopathy are the least common. Laboratory test demonstrates anemia, leukopenia, and thrombocytopenia due to hypersplenism, and normal or mild liver function abnormality. In addition, in the preclinical stage, despite the presence of abnormal portal vein during liver biopsy, no signs of portal hypertension can be detected in some patients. Therefore, the diagnosis is based on the diagnosis of exclusion and mandatory liver biopsy. The overall prognosis of idiopathic non-cirrhotic portal hypertension is better than that of patients with liver cirrhosis, but symptomatic treatment (controlling gastroesophageal varices bleeding and preventing thrombosis) is still the main treatment.

Incidence and Clinical Features of Hepatitis C Virus-associated Hepatocellular Carcinoma Patients without Liver Cirrhosis in Hepatitis B Virus-endemic Area.

Background/objective: Hepatitis C virus (HCV)-associated hepatocellular carcinoma (HCC) is rarely observed in patients without liver cirrhosis (LC). We evaluated the incidence and clinical feature of HCV-associated HCC patients with or without LC. Methods: The medical records of 1,516 patients diagnosed as having primary HCC at our hospital between January 2005 and December 2017 were retrospectively reviewed. Of these, 154 (10.2%) HCV-associated HCC patients were analyzed. LC was diagnosed histologically or clinically. Results: Seventeen (11.0%) of the 154 patients had non-cirrhotic HCC, and all were of Child-Turcotte-Pugh (CTP) class A, Among the 17 patients, 88.2% were male, all had nodular type HCC, and only 2 (11.8%) were under HCC surveillance. Median overall survival (OS) of HCV-associated HCC patients with and without LC was 15 months and 37 months, respectively. Cumulative OS rates were not different between non-cirrhotic patients and cirrhotic patients with CTP class A (P=0.229). Cumulative OS rates were significantly higher in non-cirrhotic patients than in cirrhotic patients of CTP class B (P<0.001) or C (P<0.001). Multivariate analyses showed serum AST (hazard ratio [HR] 1.01, P=0.003) and AFP levels (HR 1.01, P=0.016), antiviral therapy (HR 0.25, P=0.022), and LC of CTP class B (HR, 5.24, P=0.006) or C (HR 21.79, P<0.001) were significantly associated with prognosis in HCV-associated HCC patients. Conclusions: HCC in a non-cirrhotic liver was found in 11% of HCV-associated HCC patients. OSs of HCV-associated HCC patients were better in those of CTP A, regardless of LC than in those with LC of CTP class B or C.

Systematic review of outcomes and meta-analysis of risk factors for prognosis after liver resection for hepatocellular carcinoma without cirrhosis.

Long-term overall survival (OS) after liver resection for non-cirrhotic hepatocellular carcinoma (NCHCC) has been reported recently. The aim of this study was to review outcomes systematically and analyze risk factors for survival after surgical resection for HCC without cirrhosis. A literature search was performed of the PubMed and Embase databases for papers published between January 1995 and October 2012, which focused on hepatic resection for HCC without underlying cirrhosis. Cochrane systematic review methodology was used for this review. Outcomes were OS, operative mortality and disease-free survival (DFS). Pooled hazard ratios (HR) were calculated using the random effects model for parameters considered as potential prognostic factors. Totally, 26 retrospective case series were eligible for inclusion. The 1-, 3- and 5-year OS rate after surgical resection of NCHCC ranged from 62% to 100%, 46.3%-78.0%, and 30%-64%, respectively. The corresponding DFS rates ranged from 48.7% to 84%, 31.0%-66.0%, and 24.0%-58.0%, respectively. Five variables were related to poor survival: multiple tumors (HR 1.68, 95%CI 1.25-2.11); larger tumor size (HR 2.66, 95%CI 1.69-3.63); non-clear resection margin (R0 resection) (HR 3.52, 95%CI 1.63-5.42); poor tumor stage (HR 2.61, 95%CI 1.64-3.58); and invasion of the lymphatic vessels (HR 4.85, 95%CI 2.67-7.02). In sum, hepatic resection provides excellent OS rates for patients with NCHCC, and results have tended to improve recently. Risk factors for poor prognosis comprise multiple tumors, lager tumor size, non-R0 resection and invasion of the lymphatic vessels.

COVID-19 Presenting as Banti's Syndrome.

COVID causing Banti's syndrome has not been reported in literature yet. Banti's syndrome is a rare disorder characterized by splenomegaly, ascites, and portal hypertension without coexisting cirrhosis of the liver. Here we report a case of a 32-year-old man who presented with hematemesis, and further workup revealed that the patient had bleeding varices, ascites, and splenomegaly, thus completing the picture of Banti's syndrome. Although this is a rare disorder, Banti's syndrome must be taken into account in a patient presenting with hematemesis and splenomegaly. The patient had flu-like symptoms for three weeks but did not seek any medical help and eventually presented with Banti's syndrome. His serology was positive for COVID-19. The coronavirus (COVID-19), discovered in 2019, has been creating havoc since it first emerged in China and is now spreading worldwide. Its presentation is somewhat similar to influenza.

The characteristics and risk factors of hepatocellular carcinoma in nonalcoholic fatty liver disease without cirrhosis.

BACKGROUND AND AIM: We evaluated the characteristics of hepatocellular carcinoma (HCC) in patients who had non-alcoholic fatty liver disease (NAFLD) without cirrhosis. METHODS: We prospectively followed NAFLD patients at our University hospital. NAFLD was diagnosed from detection of steatosis by histology or imaging, no alcohol intake, and exclusion of other liver diseases. Cirrhosis was defined by histological features, imaging data, and symptoms. We compared NAFLD-related HCC with or without cirrhosis and non-cirrhotic NAFLD with or without HCC. RESULTS: There were 48 non-cirrhotic HCC patients and 71 cirrhotic HCC patients. Multiple logistic regression analysis revealed that other than liver function factors, male gender (OR: 5.603, 95%CI: 1.577-19.900), light drinker (OR: 2.797, 95%CI: 1.031-7.589), and tumor size (OR: 1.031, 95%CI 1.009-1.055) differ significantly between these two groups. The recurrence rate was significantly lower in the non-cirrhotic HCC group than the cirrhotic HCC group, with risk factors being des-γ-carboxy prothrombin and the number of HCCs. The non-cirrhotic HCC group showed significantly better survival because of absence of non-cancerous liver failure. Comparison between non-cirrhotic NAFLD patients with or without HCC (n = 612) revealed the following risk factors for HCC: male gender (OR: 7.774, 95%CI: 2.176-27.775), light drinker (OR: 4.893, 95%CI: 1.923-12.449), and high FIB4 index (OR 2.634, 95%CI: 1.787-3.884). CONCLUSION: In patients with non-cirrhotic NAFLD, important risk factors for HCC were male gender, alcohol consumption, and the FIB4 index. HCC recurrence and survival were only influenced by the tumor stage. We should be aware of alcohol consumption as a modifiable risk factor for HCC.

Surgical outcomes between patients with and without a cirrhotic liver undergoing laparoscopic liver resection: A meta-analysis.

BACKGROUND: Laparoscopic surgery in patients with liver cirrhosis (CL) is considered to be challenging. Recent studies have shown that laparoscopic liver resection (LLR) is more beneficial of reduced operative stress and postoperative complications in patients with CL. AIM: A meta-analysis was done to review the currently available published data comparing LLR for patients with CL versus those non-cirrhosis of the liver (NCL). METHODS: The electronic databases of PubMed, Wiley, Web of Science, Embase, and the Cochrane Library were searched from date of inception to January 29, 2018. Studies reporting a comparison of outcomes and methods of LLR in CL and NCL groups were included. The studies were evaluated using the modified Newcastle-Ottawa Scale. RESULTS: A total of 1573 patients from six cohort studies were included in final analysis. The CL group had a slightly shorter operative time compared with the NCL group (weighted mean difference [WMD], 18.78min shorter; 95% confidence interval [CI], -43.54-5.98; P=0.14) and delayed hospital stay (WMD, 1.26 days longer; 95% CI, -0.05-2.56; P=0.06). Blood loss, blood transfusion rate, mortality, and conversion rate did not differ significantly between the groups. CONCLUSIONS: LLR is safe and feasible in the CL compared with the NCL groups. Our present review indicates that LLR should be considered when selecting surgery for patients with CL.

Esophagogastric varices were diagnosed in a non-cirrhotic liver case during long-term follow-up after oxaliplatin-based chemotherapy.

Oxaliplatin, a chemotherapeutic agent for colorectal cancer, has been associated with pathological evidence of sinusoidal endothelial injury in the liver. However, esophagogastric varices are a poorly recognized outcome of oxaliplatin-based chemotherapy. We report a 78-year-old man, whose past history of colon cancer was resection and treatment with mFOLFOX6 for 20 weeks, as adjuvant chemotherapy. After 3.5-year follow-up of the oxaliplatin-based chemotherapy, he was diagnosed with esophageal varices without liver dysfunction, indicating that the hepatotoxicity caused by oxaliplatin could be prolonged after its administration. Patients who have received oxaliplatin-based chemotherapy should be followed up carefully over the long term.

Influence of insulin resistance on the development of hepatocellular carcinoma after antiviral treatment for non-cirrhotic patients with chronic hepatitis C.

BACKGROUND: Insulin resistance is considered to be an important factor in the progression of fibrosis and the enhancement of the risk of hepatocellular carcinoma (HCC) for chronic hepatitis C patients. The aim of this study was to assess the effect of insulin resistance on the development of HCC by non-cirrhotic chronic hepatitis C patients treated with pegylated interferon alpha-2b (PEG-IFNα2b) and ribavirin. METHODS: This retrospective study consisted of 474 Japanese non-cirrhotic patients with chronic hepatitis C. The cumulative incidence of HCC was estimated using the Kaplan-Meier method, according to insulin resistance by the homeostasis model assessment of insulin resistance (HOMA-IR) and treatment outcome. RESULTS: The overall sustained virological response (SVR) rate was 45.1 % (214/474, genotype 1: 35.4 % [129/364] and genotype 2: 77.3 % [85/110]). Twenty-one (4.4 %) patients developed HCC during the follow-up period. The 5-year cumulative incidence of HCC of the SVR group (2.6 %) was significantly lower than that of the non-SVR group (9.7 %) (log-rank test: P = 0.025). In multivariable logistic regression analysis, HOMA-IR (≥2.5) (hazard ratio [HR] 12.8, P = 0.0006), fibrosis status (F3) (HR 8.85, P < 0.0001), and post-treatment alanine aminotransferase (ALT) level (≥40 U/L) (HR 4.33, P = 0.036) were independently correlated to the development of HCC. Receiver operating characteristic analysis to determine the optimal threshold value of HOMA-IR for predicting the development of HCC in the non-SVR group showed that the areas under the curve was high (0.80, cutoff value: 3.0). Only three patients (1.4 %) who achieved SVR developed HCC. Two of them had severe insulin resistance and did not show improvement in HOMA-IR after achieving SVR. CONCLUSIONS: Insulin resistance has a strong impact on the development of HCC by non-cirrhotic patients who have PEG-IFNα2b and ribavirin treatment failure.

Outcomes after curative hepatectomy in patients with non-B non-C hepatocellular carcinoma and hepatitis B virus hepatocellular carcinoma from non-cirrhotic liver.

BACKGROUNDS AND OBJECTIVE: There is controversy regarding liver function of non-B, non-C hepatocellular carcinoma (NBNC-HCC) patients, the biological behavior of their tumors, and the outcome after surgical treatment. The aims of the present study were to compare clinicopathologic data and long-term clinical outcomes between NBNC-HCC patients and hepatitis B virus HCC (HBV-HCC) patients from non-cirrhotic liver after curative hepatectomy. METHODS: Data for HBV-HCC patients (n = 360) and NBNC-HCC patients (n = 103) were retrospectively reviewed. RESULTS: The median age of patients in the NBNC group was significantly higher than that of the HBV group (63 years vs. 53 years, P < 0.001). Tumor size in the NBNC group was greater than that in the HBV group (5.1 cm vs. 3.8 cm, P < 0.001). Regarding liver histology, the grade of lobular activity, periportal activity, and fibrosis in the HBV group was higher than in the NBNC group (P < 0.001, P < 0.001, and P < 0.001, respectively). There were no statistically significant differences in disease-free survival and overall survival between the two groups (P = 0.257 and P = 0.579, respectively). Multivariate analysis showed that increased tumor size, microvascular invasion, and intrahepatic metastasis were associated with tumor recurrence after curative liver resection. CONCLUSION: For patients with non-cirrhotic liver, clinical outcomes for NBNC-HCC were comparable to those for HBV-HCC after curative hepatectomy.

Tumour size and differentiation predict survival after liver resection for hepatocellular carcinoma arising from non-cirrhotic and non-fibrotic liver: a case-controlled study.

AIMS: The aims of this study were to assess the outcomes of patients who underwent potentially curative hepatic resection for hepatocellular carcinoma (HCC) in a background of non-cirrhotic/non-fibrotic livers, and to determine prognostic factors that influenced survival. METHODS: Over a 15-year period, all patients undergoing hepatectomy for HCC were identified. Collated data included demographics, laboratory analysis, operative findings and histo-pathological data. Survival differences between these factors following liver resection were determined. RESULTS: 57 patients were included with a median age of 70 years. The majority of patients underwent a hemi-hepatectomy or more radical resection (n = 37). Overall R0 resection rate was 90.4% (n = 51). The overall morbidity and mortality rates were 26.3% and 3.5%, respectively. The median follow-up period was 28 months. The 1-, 3- and 5- year disease-free survival was 65.4%, 41.8% and 39.1%, and the overall survival was 73.5%, 49.6% and 39.5%, respectively. AFP (p = 0.039) was the only predictor of poorer disease-free survival on univariate analysis. On multi-variable analysis, poorly differentiated tumour and large tumour size were independent predictors of overall survival. CONCLUSIONS: Liver resection is a feasible treatment option for HCC in non-cirrhotic/non-fibrotic livers with good survival outcome. Tumour size and differentiation are adverse predictors of outcome in these patients.
