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]

Intraoperative blood loss (IBL) during liver resection is a predictor of morbidity, mortality, and tumor recurrence after hepatectomy; however, there have been few reports on patient factors associated with increased IBL. We enrolled consecutive patients who underwent liver resection for primary liver malignancies, and evaluated the predictors of IBL using a data set in which factors that might influence IBL, such as surgical devices, methods and anesthetic technique, were all standardized. We studied 244 patients. A multivariate analysis revealed that higher IBL was an independent risk factor for post-hepatectomy liver failure grade ≥B and overall survival. Multiple linear regression analyses showed serum creatinine, clinically significant portal hypertension (CSPH), tumor size, and major hepatectomy were all significant predictors of IBL. In conclusion, higher IBL was significantly associated with increased morbidity and mortality in patients with primary HCC who underwent liver resection. The risk of IBL was related to several factors including tumor size, serum creatinine, CSPH, and major hepatectomy. [ABSTRACT FROM AUTHOR]
