Various models have been proposed for predicting the outcome of patients with HCC. We aim to compare the prognostic abilities of Child-Pugh, MELD, MELD-Na, and ALBI scores for predicting in-hospital mortality of HCC. Methods: We enrolled patients diagnosed with liver cirrhosis and HCC from May 2017 through May 2018. We further divided eligible patients into hepatitis B virus (HBV), patients without ascites, and patients with ascites subgroups. Areas under the characteristic curves (AUCs) were analyzed. Results: A total of 495 patients were included in the study. We collected data on patients at admission. A majority of patients were infected with HBV (91.5%). None of them were complicated with hepatic encephalopathy. Only 14.9% of patients presented with ascites. In the whole population, AUCs with 95% confidence interval (CI) of Child-Pugh, ALBI, MELD, and MELD-Na scores in predicting in-hospital mortality were 0.889 (95% CI: 0.858 - 0.915), 0.849 (95% CI: 0.814 - 0.879), 0.669 (95% CI: 0.626 - 0.711), and 0.721 (95% CI: 0.679 - 0.760), respectively. In the patients without ascites subgroup, Child-Pugh showed better discriminatory ability than ALBI score in predicting in-hospital mortality (P = 0.0002), while there were no significant differences among other comparisons. Conclusions: Child-Pugh and ALBI may be useful predictors for predicting in-hospital mortality in whole patients, in patients with HBV infection, and in patients without ascites. In HCC patients with ascites, MELD-Na may be effective for predicting in-hospital mortality.展开更多

In HCC patients with ascites, MELD-Na may be effective for predicting in-hospital mortality.

文摘Patient prognosis after transjugular intrahepatic portosystemic shunt(TIPS)placement is relatively poor and highly heterogeneous;therefore,a prognostic scoring system is essential for survival prediction and risk stratification.Conventional scores include the Child–Turcotte–Pugh(CTP)and model for end‐stage liver disease(MELD)scores.The CTP score was created empirically and displayed a high correlation with post‐TIPS survival.However,the inclusion of subjective parameters and the use of discrete cut‐offs limit its utility.The advantages of the MELD score include its statistical validation and objective and readily available predictors that contribute to its broad application in clinical practice to predict post‐TIPS outcomes.In addition,multiple modifications of the MELD score,by incorporating additional predictors(e.g.,MELD‐Sodium and MELD‐Sarcopenia scores),adjusting coefficients(recalibrated MELD score),or combined(MELD 3.0),have been proposed to improve the prognostic ability of the standard MELD score.Despite several updates to conventional scores,a prognostic score has been proposed(based on contemporary data)specifically for outcome prediction after TIPS placement.However,this novel score(the Freiburg index of post‐TIPS survival,FIPS)exhibited inconsistent discrimination in external validation studies,and its superiority over conventional scores remains undetermined.Additionally,several tools display potential for application in specific TIPS indications(e.g.,bilirubin‐platelet grade for refractory ascites),and biomarkers of systemic inflammation,nutritional status,liver disease progression,and cardiac decompensation may provide additional value,but require further validation.Future studies should consider the effect of TIPS placement when exploring predictors,as TIPS is a pathophysiological approach that substantially alters systemic hemodynamics and ameliorates bacterial translocation and malnutrition.
