Because of the rarity of invasive treatment for hepatocellular carcinoma (HCC) in patients on hemodialysis (HD) for end-stage renal disease (ESRD), the risks associated with radiofrequency ablation (RFA) in such patients remain uncertain. We used a nationwide database to investigate in-hospital mortality and hemorrhagic complications following RFA in patients on HD for ESRD.Using the Japanese Diagnosis Procedure Combination database, we enrolled patients on HD for ESRD who underwent RFA for HCC. For each patient, we randomly selected up to four non-dialyzed patients using a matched-pair sampling method based on patient age, sex, treatment hospital, and treatment year. In-hospital mortality and hemorrhagic complications were compared between dialyzed and non-dialyzed patients following RFA.We compared matched-pair samples of 437 dialyzed and 1345 non-dialyzed patients. In patients on HD for ESRD, mortality was significantly lower in those aged ≤70 years than in older patients (p = 0.02). In-hospital mortality was significantly higher in dialyzed ESRD patients than in non-dialyzed patients (1.1% vs. 0.15%, respectively; odds ratio [OR] = 7.77, p < 0.001). Hemorrhagic complications differed significantly between dialyzed ESRD patients and non-dialyzed patients (3.4% vs. 0.87%, respectively; OR = 4.75, p < 0.001).In-hospital mortality following RFA was higher in dialyzed ESRD patients than in non dialyzed patients. The indications for RFA in dialysis-dependent patients should be considered carefully. Patient age may be a useful indicator when considering RFA for HCC in patients on HD for ESRD. Pubmed
