Abstract
Introduction: Regional therapy with trans-arterial chemoembolization (TACE) is a common treatment for unresectable hepatocellular carcinoma (HCC). Outcomes were examined in patients with the best radiological response (BR) after the initial TACE. Methods: This was a retrospective cohort study of patients who underwent TACE as the initial treatment for HCC between the years 2000 and 2010. BR was defined as complete disappearance of the tumour or no enhancement with contrast on the first cross-sectional imaging study after the initial TACE. Results: Seventy-eight out of 104 total consecutive patients were identified with the potential for a BR to TACE therapy for unresectable HCC, and 24 met the criteria for BR. Patients with BR had a median survival of 12.8 months (2.2-54.9) compared with 18.9 months(1.3-56.7) for the entire cohort (P= 0.313). The median time to progression was 10.6 months (1.2-24.3) in the BR group and 3.2 months (0.7-49.2) in the patients without a BR (P= 0.003). Discussion: BR to initial TACE for unresectable HCC is associated with comparable survival to those without BR in spite of a longer time to cancer progression. It may be reasonable to consider further therapy such as repeat TACE or biological/systemic therapy in patients with HCC even when the radiological response to the initial TACE is favourable.
