ABSTRACT
BACKGROUND: Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver. Most patients with HCC are unsuitable for surgical therapies. Therefore, nonsurgical therapies play a central role in the management of this disease. Several percutaneous treatment modalities are available for HCC including radiofrequency ablation (RFA), transarterial chemoembolization (TACE), and transarterial radioembolization (TARE). In this study, we aim to evaluate the clinical outcomes, morbidity and mortality rates, and survival rates of four treatment modalities for HCC (RFA, TACE, TARE, and Sorafenib) and compare the success rate of each modality. METHODS: A retrospective observational study was conducted at King Abdulaziz Medical City in Jeddah, Saudi Arabia. The inclusion criteria were composed of patients diagnosed with HCC who received RFA, TACE, TARE, or Sorafenib treatments between 2008 and 2017. The primary outcome of this study was recurrence-free patients at the last follow-up. RESULTS: A total of 108 patients were included in this study. The mean age of the patients was 68.01 ± 9.98 years. Eighty-Two patients (75.9%) underwent interventions with the intention to cure or stabilize HCC, while twentysix patients (24.1%) were started on Sorafenib as a palliative treatment. The five years recurrence-free rates were 41.2% with RFA, 40% with the combination of TACE and RFA, 23.3% with TACE, and 0% with TARE. All patients on Sorafenib died from advanced-stage HCC. CONCLUSION: This study provides further evidence for the efficacy of several treatment modalities for the management of HCC. RFA and the combination of TACE and RFA showed better outcomes with a recurrence-free rate reaching up to 40%. TACE had a moderate survival benefit up to 23.3%. TARE showed negative survival benefits. Sorafenib continues to be an important palliative treatment but does not offer curative potential.
