Background: The aim of this study was to compare the outcome of patients with hepatocellular carcinoma (HCC), Barcelona Clinic Liver Cancer (BCLC) stages 0 and A, and portal hypertension (PHT) who underwent liver resection (LR) or radiofrequency ablation (RFA). Methods: The study population consisted of 121 patients with PHT and HCC of BCLC stage 0 and A who underwent LR ( n = 81) or RFA ( n = 40). To reduce bias in patient selection, the different covariate distributions in two groups were adjusted using inverse probability treatment weighting (IPTW). The prognostic outcomes of LR- and RFA-treated patients were then analyzed. Results: Before IPTW adjustment, the 5-year overall survival (OS) of LR and RFA patients was comparable. Five-year recurrence-free survival (RFS) was significantly better in the LR group than in the RFA group ( P < 0.0001). Multivariate analysis showed that RFA was an independent predictor of worse RFS ( P = 0.0004). The local recurrence rate was higher in the RFA than in the LR group, with recurrences in each group tending to be treated with the same modality as initially. After IPTW adjustment, the OS of patients in the LR and RFA groups did not significantly differ, whereas the RFS of the LR group remained significantly better than that of the RFA group ( P = 0.00014). However, the RFA group had fewer postoperative complication rates and a shortened length of hospital stay. Conclusions: By reducing postoperative complications, LR may be a treatment option for patients with BCLC stage 0 or A HCC and PHT. [ABSTRACT FROM AUTHOR]

Background: The management of hepatocellular carcinoma (HCC) in patients with concomitant esophageal varices (EV) remains controversial. We assessed the surgical outcome of hepatectomy and aimed to clarify the indications and management of HCC in patients with concomitant EV. Methods: We retrospectively enrolled 502 patients with HCC (100 with and 402 without EV), who underwent curative hepatectomy. We analyzed the prognostic outcomes and risk factors for EV bleeding after hepatectomy. Results: Overall survival (OS) was significantly lower in HCC patients with EV than in those without EV ( p = 0.003), although recurrence-free survival was similar in both groups. Multivariate analysis showed that indocyanine green retention test at 15 min (ICGR) >17 % ( p = 0.007) and α-fetoprotein >12.5 ng/ml ( p = 0.003) was independent predictors of poorer OS. Among patients with EV who underwent hepatectomy, multivariate analysis identified ICGR >17 % ( p = 0.03) as the only independent predictor of poorer OS. There was no significant difference in OS between HCC patients with EV and ICGR ≤17.0 % and HCC patients without EV. Ten patients experienced EV bleeding after hepatectomy. Multivariate analysis showed that preoperative endoscopic findings of blue color EV ( p = 0.008) and red color sign ( p = 0.0005) were independent predictors of EV bleeding in patients with HCC after hepatectomy. Conclusions: These results suggest that HCC patients with EV and ICGR ≤17 % may be suitable for surgery, but patients with preoperative endoscopic blue color EV and red color sign need to be managed appropriately.

Introduction: Previous reports have indicated an association between blood transfusion and prognosis of hepatocellular carcinoma (HCC) after hepatectomy. However, clinicopathological biases were not adjusted in these studies. We aimed to clarify the effect of blood transfusions in patients with HCC and Child-Pugh class A after hepatectomy by using inverse probability of treatment weighting (IPTW) analysis for selection bias control. Materials and methods: We enrolled 479 patients with primary HCC and Child-Pugh class A retrospectively (91 transfused and 388 nontransfused patients) who underwent curative hepatectomy. After adjusting for different covariate distributions for both groups by IPTW, we analyzed the prognostic outcomes. Results: In the unweighted analyses, overall survival (OS) rate of transfused patients was significantly lower than in nontransfused patients ( P < 0.0001). Recurrence-free survival (RFS) rate of transfused patients was significantly lower than that of nontransfused patients ( P = 0.0024). Multivariate analysis showed that blood transfusion was an independent prognostic factor of OS and RFS. The different distributive covariates between the two groups were age, presence of liver cirrhosis, serum level of alpha-fetoprotein, maximum tumor diameter, and amount of intraoperative blood loss. After IPTW by these covariates, OS rate of transfused patients was not significantly lower than those of nontransfused patients, whereas RFS rate of transfused patients remained significantly lower than those of nontransfused patients ( P = 0.038, adjusted HR 1.45; 95 % CI 1.0-2.1). Conclusions: These results suggest that blood transfusion was associated with recurrence of HCC after hepatectomy in patients with HCC and Child-Pugh class A. [ABSTRACT FROM AUTHOR]
