%X BACKGROUND: Large hepatocellular carcinoma (HCC) treatment options have obvious limitations. Our trial comprises ipsilateral hepatic artery ligation and extrahepatic collaterals division (HALED, reinforced by percutaneous tumor injection controlling residual HCC arterial supply. We aimed to evaluate the long term safety and feasibility of the Combined Surgical and Injection of alcohol Treatment (COSIT) as a novel therapy for the large HCC.
METHODS: Candidates' clinical data of the of this case series were prospectively and sequentially reported in accordance with stage 2a development IDEAL (Idea, Development, Exploration, Assessment and Long-term monitoring) recommendations. It included adult patients with HCC (diameter >5 cm) subjected to COSIT coming to our center during a five years' trial evaluating the long term outcome measures. Study ID (NCT03138044 ClinicalTrials.gov).
RESULTS: Patients were 21, their mean age (±standard deviation) was 61·9 (±9·3) years. Eleven (52.4%) patients had tumors diameter >10 cm. 17 (80.9%) patients were advanced BCLC stage. Six modifications were made in this injection phase till it came to a stability. The mean alcohol volume was 72.0 mls. The mean follow-up duration was 16 months. The median overall survival duration was 14 months. The one, three and five years' survival was 71.4%, 23.8% and 4.8%, respectively. Grade 3/4 and 4 Common Toxicity Criteria for Adverse Effects (v4.03) were encountered in 10 (47.6%) and one (4.8%) patients, respectively.
CONCLUSIONS: This preliminary findings of COSIT can be a promising alternative treatment for patients having large HCC. Consequently, a multicenter stage 2b Exploration IDEAL trial is suggested.
