Stratified Platelet-to-lymphocyte Ratio: A Novel Target for Prognostic Prediction of Hepatocellular Carcinoma after Curative Liver Resection.

Background and Aims: Platelet-to-lymphocyte ratio (PLR) has been shown to predict prognosis of cancers. We aimed to evaluate the prognostic value of stratification of PLR in patients after curative liver resection (CLR) for hepatocellular carcinoma (HCC). Methods: A total of 1804 patients who underwent CLR for suspected HCC between January 2007 and January 2014 were screened for the study. All of the patients were categorized into equal tertiles according to the number of patients and the distribution of PLR. Prognostic significance was determined for overall survival (OS) and was assessed using Kaplan-Meier analysis. Univariate and multivariate Cox proportional hazard regression analyses were evaluated for association of all independent parameters with disease prognosis. Results: The optimal cut-off points of preoperative PLR were: (T1) 11.98-75.00, (T2) 75.00-113.33 and (T3) 113.33-567.50. There were obvious differences in each PLR tertile with mortality within 36 months of CLR (plog-rank < 0.001). Multivariable analysis suggested that the level of PLR (HR = 1.004, 95%CI: 1.001-1.008, p = 0.006), portal vein thrombosis (HR = 3.406, 95%CI: 1.185-9.794, p = 0.023), number of nodules (HR = 1.810, 95%CI: 1.345-2.437, p < 0.001), Child-Turcotte-Pugh score (HR = 1.741, 95%CI: 1.129-2.684, p = 0.012) and microvascular invasion (HR = 2.730, 95%CI: 1.777-4.196, p < 0.001) were significant predictors of mortality. Kaplan-Meier analysis of overall survival (OS) demonstrated that each PLR tertile showed a progressively worse OS and apparent separation (plog-rank = 0.016). The highest 5-year OS rate following CLR (58%) was revealed in tertile 1. In contrast, the lowest 5-year OS rate (30%) was revealed in tertile 3. Conclusion: Stratified preoperative PLR could strengthen the predictive power for OS in HCC patients with CLR.

Systematic review with network meta-analysis: statins and risk of hepatocellular carcinoma.

OBJECTIVES: Usage of statins is suggested to decrease the incidence of HCC. When it comes to different statin subtypes, the chemopreventive action remains controversial. We aim to compare the usage of different statins and reduction of HCC risk. METHODS: We searched PubMed, Embase.com and Cochrane Library database up to August 10, 2015. Duplicated or overlapping reports were eliminated. We performed a traditional pair-wise meta-analysis and a Bayesian network meta-analysis to compare different treatments with a random-effects model. RESULTS: We reviewed five observational studies enrolling a total of 87127 patients who received at least two different treatment strategies including rosuvastatin, atorvastatin, simvastatin, pravastatin, fluvastatin, cerivastatin, and lovastatin or observation alone. Direct comparisons showed that usage of atorvastatin (OR 0.63, 95%CI 0.45-0.89) and fluvastatin (OR 0.58, 95%CI 0.40-0.85) could significantly cut the risk of liver cancer. The difference of indirect comparisons between the included regimens is not statistically significant. However, usage of all types of statins, such as fluvastatin (RR 0.55, 95%CI 0.26-1.11), atorvastatin (RR 0.59, 95%CI 0.30-1.16), simvastatin (RR 0.69, 95%CI 0.38-1.25), cerivastatin (RR 0.71, 95%CI 0.19-2.70), pravastatin (RR 0.72, 95%CI 0.37-1.45), lovastatin (RR 0.81, 95%CI 0.34-1.96) and rosuvastatin (RR 0.92, 95%CI 0.44-1.80), appeared to be superior to observation alone. Notably, fluvastatin was hierarchically the best when compared with the six other statins. CONCLUSIONS: Our analyses indicate the superiority of usage of statins in reduction of liver cancer. Available evidence supports that fluvastatin is the most effective strategy for reducing HCC risk compared with other statin interventions.

Comparative efficacy of oral nucleotide analogues for the prophylaxis of hepatitis B virus recurrence after liver transplantation: a network meta-analysis.

BACKGROUND: Prophylactic nucleos(t)ide anologues against hepatitis B virus (HBV) recurrence after liver transplantation (LT) include lamivudine, entecavir, tenofovir, adefovir. Since the most effective strategies for post-LT remain inconclusive, we aimed to compare 6 different treatment options (lamivudine, entecavir, tenofovir, adefovir, lamivudine plus adefovir, lamivudine plus tenofovir) in terms of HBV recurrence after LT using network meta-analysis. METHODS: The search identified seventeen studies involving 6 different prophylactic regimens covering 7274 patients. RESULTS: Compared with entecavir, lamivudine plus tenofovir (OR 2.00, 95%CI 0.02-183.29), lamivudine plus adefovir, (OR 2.83, 95%CI 0.18-33.57), tenofovir (OR 1.11, 95%CI 0.22-5.80), adefovir (OR 3.78, 95%CI 0.59-22.16), lamivudine (OR 4.62, 95%CI 1.75-11.39) were associated with an increased risk of HBV recurrence. CONCLUSION: Entecavir resulted with the highest probability (31%) as the best prophylactic option on reducing the risk of HBV recurrence. Entecavir is the preferred oral NAs treatment compared to other five different prophylactic regimens in the prevention of HBV recurrence after LT.

Combined AFP-CRUT with microvascular invasion accurately predicts mortality risk in patients with hepatocellular carcinoma following curative liver resection.

AIMS: To establish and validate an equation of α-fetoprotein (AFP) change rate over unit time (AFP-CRUT) as a potential predictor of survival after resection in patients with hepatocellular carcinoma (HCC). METHODS: The AFP-CRUT was constructed based on dynamic variation in AFP over time and then categorized into quintiles. The area under the receiver operating characteristic (ROC) curve showed the performance for survival prediction. RESULTS: As independent risk factors associated with mortality, microvascular invasion (MVI) (p = 0.003) and AFP-CRUT quintiles (p = 0.048) were combined to enhance the predictive effect. The highest 5-year overall survival rate following curative liver resection (93%) was observed in patients with MVI absent and AFP-CRUT in quintile 1 (49.64 to 209.61). In contrast, the lowest 5-year overall survival (7%) was obtained in quintile 5 (-469.29 to 6.45) with MVI present. In validation cohorts at both 12 and 24 months, AFP-CRUT performed well as a potential prognostic biomarker. CONCLUSIONS: Combining AFP-CRUT quintiles with MVI may predict significantly improved outcomes and enhance the predictive power for patient responses to therapeutic intervention.
