Temporal trends and long-term outcomes of radiofrequency ablation for hepatocellular carcinoma within the Milan criteria.

ABSTRACT: No study has analysed the temporal trends of the long-term results and clinical characteristics of patients with hepatocellular carcinoma (HCC) treated using radiofrequency ablation (RFA). Therefore, we examined temporal trends of characteristics of patients and treatment-naïve HCCs within the Milan criteria treated by RFA over 20 years. We retrospectively analysed 1099 patients with HCC within the Milan criteria treated with percutaneous RFA from January 2000 to December 2019. The overall survival (OS), recurrence-free survival (RFS), and factors affecting survival and local tumor progression were analysed using the Kaplan‒Meier method and Cox proportional hazards model. A trend test was performed to analyse the changing trends in participants and treatment outcomes. The overall and RFS of patients improved during the later period. In addition, viral hepatitis-related HCC incidence decreased, whereas that of alcohol- or non-alcoholic fatty liver disease-related HCC increased from the earlier to the later period (P for trend < 0.001). HBV antiviral therapy was increased and improved OS and RFS in patients treated using RFA. The outcomes after RFA over a 20-year period improved due to changes over time in target tumors and patients. The results could be useful for selecting patients who will benefit from RFA.

Project description:BackgroundIntrahepatic distant recurrence (IDR) is a significant problem for patients who have undergone radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). The objective of the study was to investigate risk factors and to predict outcomes of recurrent IDR within Milan criteria after complete RFA for primary early-stage HCC.MethodThis retrospective study reviewed 449 patients with intrahepatic distant recurrent HCC after complete RFA for early-stage HCC. After excluding 100 patients who were beyond Milan criteria, with incomplete lab data, or had follow-up less than three months, a total of 349 patient cases were compiled and their baseline characteristics, further treatment modalities after tumor recurrence and survival were analyzed.ResultsAfter a median follow-up of 36.2 months, 92 patients had expired. The majority of patients were male (59.9%) with a median age of 64.3 years (range:38-88). The cumulative 5-year overall survival (OS) rates after treatment for recurrent HCC was 67.2%. On multivariate analysis, end-stage renal disease(Hazard ratio (H.R.) = 2.33, p = 0.021), m-ALBI grade 2a (H.R. = 2.86, p = 0.003) and m-ALBI grades 2b or 3 (H.R. = 2.30, p = 0.009), APRI greater than 1 (H.R. = 1.92, p = 0.036) and 2nd recurrence occurring within 1 year (H.R. = 2.69, p<0.001) were significantly associated with worse survival. The cumulative 5-year 2nd recurrence rate was 87.4%. On multivariate analysis, male gender (H.R. = 1.47, p = 0.01), age greater than 65 years (H.R. = 1.72, p<0.001), an alpha fetoprotein level greater than 20ng/ml (H.R. = 1.41, p = 0.016), surgical treatment for recurrent HCC (H.R. = 0.25, p = 0.007), tumor number greater than 1 (H.R. = 1.35, p = 0.046), and IDR developing within 2 years (H.R. = 1.67, p = 0.001) were prognostic factors for 2nd recurrence.ConclusionOur study suggested that presence of end-stage renal disease, m-ALBI grades 2 and 3, APRI >1 and time to 2nd HCC recurrence were all associated with overall survival while the 2nd HCC recurrence was associated with male gender, age ≥65 years, α-fetoprotein level >20 ng/mL, non-surgical therapy, time to IDR, and tumor number> 1.
