Type 2 diabetes mellitus is a recognized risk factor for HCC in patients with liver disease, independent from the etiology of their liver disease. Hence, prevention and treatment of type 2 diabetes ...mellitus and its underlying cause, insulin resistance, should be considered a treatment target for patients with liver disease. The drug armamentarium for diabetes is wide and consists of agents with insulin‐sensitizing activity, agents that stimulate insulin secretion, insulin itself, and agents that reduce gastrointestinal and urinary glucose absorption. From an endocrinology perspective, the main goal of treatment is the achievement of euglycemia; however, in patients at risk of, or with known underlying liver disease, the choice of diabetic medication as it relates to potential hepatic carcinogenesis remains complex and should be carefully considered. In the last decade, increasing evidence has suggested that metformin may reduce the risk of HCC, whereas evidence for other classes of diabetic medications, particularly some of the newer agents including the sodium glucose cotransporter‐2 inhibitors and glucagon‐like peptide‐1 receptor agonists, is fewer and often inconsistent. In this review, we aim to summarize the current evidence on the potential effects of the most widely used diabetic agents on liver cancer tumorigenesis.
Metabolic dysfunction-associated fatty liver disease (MAFLD) represents a new inclusive definition of the whole spectrum of liver diseases associated to metabolic disorders. The main objective of ...this study was to compare patients with MAFLD and non-MAFLD with hepatocellular carcinoma (HCC) included in a nationally representative cohort.
We analysed 6882 consecutive patients with HCC enrolled from 2002 to 2019 by 23 Italian Liver Cancer centres to compare epidemiological and future trends in three subgroups: pure, single aetiology MAFLD (S-MAFLD); mixed aetiology MAFLD (metabolic and others, M-MAFLD); and non-MAFLD HCC.
MAFLD was diagnosed in the majority of patients with HCC (68.4%). The proportion of both total MAFLD and S-MAFLD HCC significantly increased over time (from 50.4% and 3.6% in 2002-2003, to 77.3% and 28.9% in 2018-2019, respectively, p<0.001). In Italy S-MAFLD HCC is expected to overcome M-MAFLD HCC in about 6 years. Patients with S-MAFLD HCC were older, more frequently men and less frequently cirrhotic with clinically relevant portal hypertension and a surveillance-related diagnosis. They had more frequently large tumours and extrahepatic metastases. After weighting, and compared with patients with non-MAFLD, S-MAFLD and M-MAFLD HCC showed a significantly lower overall (p=0.026, p=0.004) and HCC-related (p<0.001, for both) risk of death. Patients with S-MAFLD HCC showed a significantly higher risk of non-HCC-related death (p=0.006).
The prevalence of MAFLD HCC in Italy is rapidly increasing to cover the majority of patients with HCC. Despite a less favourable cancer stage at diagnosis, patients with MAFLD HCC have a lower risk of HCC-related death, suggesting reduced cancer aggressiveness.
The prognosis of untreated patients with hepatocellular carcinoma (HCC) is heterogeneous, and survival data were mainly obtained from control arms of randomized studies. Clinical practice data on ...this topic are urgently needed, so as to help plan studies and counsel patients. We assessed the prognosis of 600 untreated patients with HCC managed by the Italian Liver Cancer Group. Prognosis was evaluated by subdividing patients according to the Barcelona Clinic Liver Cancer (BCLC) classification. We also assessed the main demographic, clinical, and oncological determinants of survival in the subgroup of patients with advanced HCC (BCLC C). Advanced (BCLC C: n = 138; 23.0%) and end‐stage HCC (BCLC D; n = 210; 35.0%) represented the majority of patients. Overall median survival was 9 months, and the principal cause of death was tumor progression (n = 279; 46.5%). Patients' median survival progressively and significantly decreased as BCLC stage worsened (BCLC 0: 38 months; BCLC A: 25 months; BCLC B: 10 months; BCLC C: 7 months; BCLC D: 6 months; P < 0.0001). Female gender (hazard ratio HR = 0.55; 95% confidence interval CI = 0.33‐0.90; P = 0.018), ascites (HR = 1.81; 95% CI = 1.21‐2.71; P = 0.004), and multinodular (>3) HCC (HR = 1.79; 95% CI = 1.21‐2.63; P = 0.003) were independent predictors of survival in patients with advanced HCC (BCLC C). Conclusion: BCLC adequately predicts the prognosis of untreated HCC patients. In untreated patients with advanced HCC, female gender, clinical decompensation of cirrhosis, and multinodular tumor are independent prognostic predictors and should be taken into account for patient stratification in future therapeutic studies.

Isolated alterations of biochemical markers of liver damage in a seemingly healthy patient can present a challenge for the clinician. In this review we provide a guide to interpreting alterations to ...liver enzyme levels. The functional anatomy of the liver and pathophysiology of liver enzyme alteration are briefly reviewed. Using a schematic approach that classifies enzyme alterations as predominantly hepatocellular or predominantly cholestatic, we review abnormal enzymatic activity within the 2 subgroups, the most common causes of enzyme alteration and suggested initial investigations.
