Abstract

Objectives: To assess the impact of clinically significant portal hypertension (CSPH) on the prognosis of patients with hepatocellular carcinoma (HCC) undergoing radiofrequency ablation (RFA). Methods: We retrospectively enrolled 280 treatment-naïve early-stage HCC patients who had Child–Pugh grade A or B and received upper gastrointestinal endoscopy at the time of HCC diagnosis. CSPH was defined as (1) a platelet count < 100,000/mm3 associated with splenomegaly and/or (2) the presence of oesophageal/gastric varices by endoscopy. Factors determining poor overall survival and recurrence after RFA were analysed by Cox proportional hazards model and propensity score matching analysis. Results: A total of 192 (68.6 %) patients had CSPH. The cumulative 5-year survival rates were 50.6 % and 76.7 % in patients with and without CSPH, respectively (p = 0.015). Based on multivariate analysis, age > 65 years (hazard ratio (HR) 1.740, p = 0.025), serum albumin levels ≤ 3.5 g/dL (HR 3.268, p < 0.001) and multiple tumours (HR 1.693, p = 0.046), but not CSPH, were independent risk factors associated with poor overall survival after RFA. Moreover, the overall survival rates were comparable between patients with and without CSPH after adjusting for confounding factors via propensity score matching analysis. Conclusions: CSPH was not associated with poor outcomes after RFA. Key points: • CSPH was common in HCC patients who underwent RFA therapy. • CSPH was not an independent risk factor in determining poor prognosis. • Serum albumin level was more important to determine the outcomes.
