Molecular prognostic prediction in liver cirrhosis.

ABSTRACT: The natural history of cirrhosis varies and therefore prognostic prediction is critical given the sizable patient population. A variety of clinical prognostic indicators have been developed and enable patient risk stratification although their performance is somewhat limited especially within relatively earlier stage of disease. Molecular prognostic indicators are expected to refine the prediction, and potentially link a subset of patients with molecular targeted interventions that counteract poor prognosis. Here we overview clinical and molecular prognostic indicators in the literature, and discuss critical issues to successfully define, evaluate, and deploy prognostic indicators as clinical scores or tests. The use of liver biopsy has been diminishing due to sampling variability on fibrosis assessment and emergence of imaging- or lab test-based fibrosis assessment methods. However, recent rapid developments of genomics technologies and selective molecular targeted agents has highlighted the need for biopsy tissue specimen to explore and establish molecular information-guided personalized/stratified clinical care, and eventually achieve "precision medicine".

Project description:BackgroundDiagnostic criteria for sarcopenia have not been established in Chinese. This study established criteria based on the L3-skeletal muscle index (L3-SMI) and assessed its value for outcomes predicting in cirrhotic Chinese patients.MethodsTotally 911 subjects who underwent a CT scan at two centres were enrolled in Cohort 1 (394 male and 417 female subjects, aged 20-80 years). The data of those subjects younger than 60 years (365 male and 296 female subjects) were used to determine the reference intervals of the L3-SMI and its influencing factors. Cohort 2 consisted of 480 patients (286 male and 184 female patients) from three centres, and their data were used to investigate the prevalence of sarcopenia and evaluate the value of L3-SMI for predicting the prognosis and complications of cirrhosis.ResultsAge and sex had the greatest effects on the L3-SMI (P < 0.001). The L3-SMI scores were clearly higher in male patients than in female patients (52.94 ± 8.41 vs. 38.91 ± 5.65 cm2 /m2 , P < 0.001) and sharply declined in subjects aged ≥ 60 years. Based on the mean -1.28 × SD among adults aged < 60 years, the L3-SMI cut-off value for sarcopenia was 44.77 cm2 /m2 in male patients and 32.50 cm2 /m2 in female patients. Using these values, 22.5% of the cirrhotic patients (28.7% of male patients and 11.9% of female patients) were diagnosed with sarcopenia. Compared with non-sarcopenia individuals, sarcopenia patients had lower body mass index (21.28 ± 3.01 vs. 24.09 ± 3.39 kg/m2 , P < 0.001) and serum albumin levels (31.54 ± 5.93 vs. 32.93 ± 5.95 g/L, P = 0.032), longer prothrombin times (16.39 ± 3.05 vs. 15.71 ± 3.20 s, P = 0.049), higher total bilirubin concentrations (41.33 ± 57.38 vs. 32.52 ± 31.48 μmol/L, P = 0.039), worse liver function (Child-Pugh score, 8.05 ± 2.11 vs. 7.32 ± 2.05, P = 0.001), higher prevalence of cirrhosis-related complications (81.82% vs. 62.24%, P < 0.001) and mortality (30.68% vs. 11.22%, P < 0.001). Overall survival was significantly lower in the sarcopenia group [risk ratio (RR) = 2.643, 95% confidence interval (CI) 1.646-4.244, P < 0.001], accompanied with an increased cumulative incidence of ascites (RR = 1.827, 95% CI 1.259-2.651, P = 0.002), spontaneous bacterial peritonitis (RR = 3.331, 95% CI 1.404-7.903, P = 0.006), hepatic encephalopathy (RR = 1.962, 95% CI 1.070-3.600, P = 0.029), and upper gastrointestinal varices (RR = 2.138, 95% CI 1.319-3.466, P = 0.002). Subgroup analysis showed sarcopenia shortened the survival of the patients with Model For End-Stage Liver Disease score > 14 (RR = 4.310, 95% CI 2.091-8.882, P < 0.001) or Child-Pugh C (RR = 3.081, 95% CI 1.516-6.260, P = 0.002).ConclusionsSarcopenia is a common comorbidity of cirrhosis and can be used to predict cirrhosis-related complications and the prognosis.
