For the treatment of small hepatocellular carcinoma (HCC), radiofrequency ablation (RFA) is in some centers considered a first-line therapeutic option. However, such a strategy is still under debate with regard to tumor and patient characteristics. In this single-center study we assessed the 5-year survival and prognosis factors in 235 consecutive patients with cirrhosis (Child-Pugh A/B: 205/30) who received RFA as first-line treatment for up to three HCC ≤5 cm (307 tumors; mean diameter: 29 ± 10 mm; 53 multinodular forms). Among these patients, 67 satisfied the criteria for resection according to the Barcelona Clinic Liver Cancer. Complete ablation was obtained in 222 patients (94%). Overall, 337 RFA sessions were performed including iterative RFA for recurrence. Major complications occurred in three patients (0.9%), including one treatment-related death. After 27 ± 20 months of mean follow-up, local or distant, or both, tumor recurrence occurred in 16, 88, and 11 patients, respectively. Twenty-nine patients underwent transplantation and were removed from the study at this point. Overall 5-year, recurrence-free, and tumor-free (including results of iterative RFA) survival rates were, respectively, 40%, 17%, and 32%. The overall 5-year survival rate was 76% for operable patients. Factors associated with overall survival were prothrombin activity (hazard ratio [HR] = 0.97, 0.96–0.98; P < 0.0001) and serum levels of α-fetoprotein (AFP) (HR = 1.02, 1.02–1.02; P < 0.0001), and factors associated with tumor recurrence were multinodular forms (HR = 2.34; 1.52–3.6; P = 0.0001) and serum AFP levels (HR = 1.015, 1.014–1.016; P = 0.015). Tumor size was associated with local recurrence but not with overall and tumor-free survival. Conclusion: RFA is a safe and effective first-line treatment of HCC up to 5 cm in diameter, especially for patients with a single tumor, a low serum AFP level, and well-preserved liver function.

Irreversible electroporation offers a safe opportunity for complete tumor response in patients with hepatocellular carcinoma not amenable to standard local curative treatments, including thermal ablation techniques. PurposeTo assess the safety and efficacy of irreversible electroporation (IRE) in the treatment of patients with inoperable hepatocellular carcinoma (HCC) who are ineligible for thermal ablative techniques.Materials and MethodsThis retrospective study was approved by an ethics review board, and the requirement to obtain informed written consent was waived. From March 2012 to June 2015, 58 patients (median age, 65.4 years; range 41.6–90 years) with cirrhosis received IRE for the treatment of 75 HCC tumors. The median tumor diameter was 24 mm (range, 6–90 mm). IRE was selected because of tumor location (48 patients) or the patient’s poor general condition (10 patients). Treatment response was assessed with magnetic resonance (MR) imaging 1 month after treatment and every 3 months thereafter. Overall local tumor progression-free survival (PFS) per nodule (including initial treatment failures) was assessed by using the Kaplan-Meier method. The marginal Cox proportional hazards model was used to assess the fac...

Although partial splenic embolization (PSE) has been proposed in patients with cirrhosis in cases when thrombocytopenia or neutropenia may cause clinical manifestations or if there are contra-indications to other therapeutic procedures, there are limited data on long-term outcome. We provide a retrospective review of results and the tolerance of all PSE procedures in patients with cirrhosis in our department. Thirty-two consecutive patients with cirrhosis were included over a 6 year period. Indications for PSE were as follows: (1) severe cytopenia preventing necessary antiviral treatment (n=14), percutaneous destruction of hepatocellular carcinoma (n=8) or major surgery (n=3), severe purpura (n=3); (2) painful splenomegaly (n=4). After superselective catheterization, embolization was performed with up to 50% reduction of splenic blood flow. Thrombocyte and leucocyte counts increased markedly (185% and 51% at 1 month; 95% and 30% at 6 months). Thirty-one and 20 patients had platelet count >80,000/mm3 at months 1 and 6 vs only one before PSE. Overall, the aim of PSE was achieved in 27 patients (84%) (planned treatment: 20/25; disappearance of purpura and splenic pain: 7/7). Severe complications occurred in five patients (16%): transient ascites (n=2), splenic and/or portal vein thrombosis (n=2) that resolved after anticoagulation therapy, and splenic abscess (n=2) leading to death. These two patients had splenic necrosis >70%. In patients with cirrhosis, PSE may resolve cytopenia and the clinical complications related to hypersplenism or splenomegaly. However, due to a high risk of severe complications, particularly splenic abscess, the indications of PSE should be very limited and the extent of necrosis should be strictly controlled during the PSE procedure.

Hepatocellular carcinoma (HCC) is the leading cause of death in patients with cirrhosis. Patients outside clinical trials seldom benefit from evidence‐based monitoring. The objective of this study was to estimate the cost‐effectiveness of complying with HCC screening guidelines. The economic evaluation compared surveillance of patients with cirrhosis as recommended by the guidelines (“gold‐standard monitoring”) to “real‐life monitoring” from the health care system perspective. A Markov model described the history of the disease and treatment course including current first‐line curative treatment: liver resection, radiofrequency ablation (RFA), and liver transplantation. Transition probabilities were derived mainly from two French cohorts, CIRVIR and CHANGH. Costs were computed using French and U.S. tariffs. Effectiveness was measured in life years gained (LYG). An incremental cost‐effectiveness ratio (ICER) was calculated for a 10‐year horizon and tested with one‐way and probabilistic sensitivity analyses. The cost difference between the two groups was $648 ($87,476 in the gold‐standard monitoring group vs. $86,829 in the real‐life monitoring group) in France and $11,965 ($93,795 vs. $81,829) in the United States. Survival increased by 0.37 years (7.18 vs. 6.81 years). The ICER was $1,754 per LYG in France and $32,415 per LYG in the United States. The health gain resulted from earlier diagnosis and access to first‐line curative treatments, among which RFA provided the best value for money. Conclusion: Our results indicate that gold‐standard monitoring for patients with cirrhosis is cost‐effective, attributed to a higher probability of benefiting from a curative treatment and so a higher survival probability.
