The Pre- and Postoperative FIB-4 Indexes Are Good Predictors to the Outcomes of HBV-Related HCC Patients after Resection.

ABSTRACT: Background and Aim:Liver fibrosis is associated with the prognosis of patients with hepatocellular carcinoma (HCC) after resection. The fibrosis-4 (FIB-4) index is an accurate and noninvasive marker to determine the degree of liver fibrosis. Here, we evaluated the effect of pre- and postoperative FIB-4 index in predicting the outcomes after resection of HCC in patients who have chronic hepatitis B (CHB) infection. Methods:A total of 534 CHB patients with HCC who received curative hepatectomy between 2001 and 2016 at Kaohsiung Chang Gung Memorial Hospital, Taiwan, were enrolled in this study. The impact of the FIB-4 index (preoperative and the 1st year after operation) on overall survival (OS) and recurrence-free survival (RFS) was evaluated. Results:There was a significant association between the preoperative FIB-4 index and Metavir fibrosis stage (p < 0.01). The multivariate analysis showed that preoperative FIB-4 > 2 is an independent risk factor for RFS and OS after HCC curative resection [hazard ratio (HR), 1.902; 95% CI, 1.491-2.460; p < 0.001, and HR, 2.207; 95% CI, 1.420-3.429; p < 0.001, respectively]. Notably, preoperative FIB-4 is also an independent risk factor for RFS (HR, 1.219; p = 0.035) in noncirrhotic patients. Furthermore, patients had deteriorated FIB-4 1 year after operation [definition: the value?(the?1st?year?FIB-4?after?operation?minus?preoperative?FIB-4) > 1] and had an adverse outcome in RFS and OS (p < 0.001, both). Conclusion:The pre and postoperative FIB-4 indexes are useful clinical markers to predict the prognosis in HBV-HCC patients after curative hepatectomy.

Project description:Global prevalence of non-alcoholic fatty liver disease (NAFLD) has been growing in the last decades, especially in western countries, due to increased prevalence of diabetes, obesity or other components of metabolic syndrome. NAFLD recently became an important cause of hepatocellular carcinoma (HCC), even in non-cirrhotic patients. Patients with HCC-NAFLD are usually older, with more morbidities (especially cardiovascular diseases and metabolic disorders) and have advanced disease at the diagnosis due to the absence of surveillance, which is considered not cost-effective in patients without advanced fibrosis/cirrhosis, given the large prevalence of NAFLD in the general population. For these reasons, patients with HCC-NAFLD unlikely underwent curative treatments, and have been reported to have lower overall survival (OS) compared to individuals with HCC related to other aetiologies. However, this difference is not confirmed by data of patient subgroups who received curative treatment. In our review, we selected studies published over the past 8 years that analyse characteristics and outcomes of HCC-NAFLD patients who underwent surgery with the aim of identifying features that could predict outcomes and potential selection criteria. All the studies confirm that patients with HCC-NAFLD are older, with many comorbidities and that HCC occurs frequently even in non-cirrhotic livers. There is no agreement about intraoperative and perioperative complications. Regarding outcomes, all papers agree that patients with HCC in NAFLD who undergo surgery have a better OS compared to other aetiologies. Summarizing, surgery is a good curative option for patients with HCC-NAFLD, perhaps even better than transplantation in terms of OS. In this group of patients, it seems to be essential to evaluate cardio-pulmonary and general operative risk, in addition to the normal risk assessment related to liver function to avoid an underestimation, especially for patients without severe underlying ?brosis.

Project description:Hepatitis B virus (HBV) infection is a common problem in the world, especially in China. More than 60-80% of hepatocellular carcinoma (HCC) cases can be attributed to HBV infection in high HBV prevalent regions. Although traditional Sanger sequencing has been extensively used to investigate HBV sequences, NGS is becoming more commonly used. Further, it is unknown whether word pattern frequencies of HBV reads by Next Generation Sequencing (NGS) can be used to investigate HBV genotypes and predict HCC status. In this study, we used NGS to sequence the pre-S region of the HBV sequence of 94 HCC patients and 45 chronic HBV (CHB) infected individuals. Word pattern frequencies among the sequence data of all individuals were calculated and compared using the Manhattan distance. The individuals were grouped using principal coordinate analysis (PCoA) and hierarchical clustering. Word pattern frequencies were also used to build prediction models for HCC status using both K-nearest neighbors (KNN) and support vector machine (SVM). We showed the extremely high power of analyzing HBV sequences using word patterns. Our key findings include that the first principal coordinate of the PCoA analysis was highly associated with the fraction of genotype B (or C) sequences and the second principal coordinate was significantly associated with the probability of having HCC. Hierarchical clustering first groups the individuals according to their major genotypes followed by their HCC status. Using cross-validation, high area under the receiver operational characteristic curve (AUC) of around 0.88 for KNN and 0.92 for SVM were obtained. In the independent data set of 46 HCC patients and 31 CHB individuals, a good AUC score of 0.77 was obtained using SVM. It was further shown that 3000 reads for each individual can yield stable prediction results for SVM. Thus, another key finding is that word patterns can be used to predict HCC status with high accuracy. Therefore, our study shows clearly that word pattern frequencies of HBV sequences contain much information about the composition of different HBV genotypes and the HCC status of an individual.
