The efficacy of radiofrequency ablation versus cryoablation in the treatment of single hepatocellular carcinoma: A population‐based study
Abstract Background Radiofrequency ablation (RFA) is an effective treatment for single hepatocellular carcinoma (HCC), but it is difficult to use against tumors in some locations and often leads to incomplete ablation as a result of the heat‐sink effect. This study was conducted to evaluate the effi...

| description | Abstract Background Radiofrequency ablation (RFA) is an effective treatment for single hepatocellular carcinoma (HCC), but it is difficult to use against tumors in some locations and often leads to incomplete ablation as a result of the heat‐sink effect. This study was conducted to evaluate the efficacy of cryoablation compared with that of RFA in the treatment of single HCC. Methods This retrospective study was conducted based on the Surveillance, Epidemiology, and End Results (SEER) database. From 2004 to 2015, patients aged 40 to 79 diagnosed with HCC were included in the study. A propensity score matching (PSM) model was used to reduce selection biases. Results Before PSM, the median overall survival (mOS) and median cancer‐specific survival (mCSS) in the RFA group were slightly longer than those in the cryoablation group (p > 0.05). In the subgroup analysis, the mOS and mCSS of patients with tumor sizes <3, 3–5, and >5 cm who received RFA treatment were longer than those of patients given cryoablation treatment, but there was no significant difference (p > 0.05). Similar results were presented in patients at American Joint Committee on Cancer (AJCC) stages I and II. After PSM, the mOS and mCSS were slightly better in the RFA group than the cryoablation group but without significant differences. Univariate and multivariate analysis showed that cryoablation treatment was not an unfavorable factor for OS and CSS before or after PSM (p > 0.05). In the multivariable competing risk model, non‐cancer‐specific death was taken as a competing factor and cryoablation was also not unfavorable for the survival of patients before and after PSM (p > 0.05). Conclusion Cryoablation is non‐inferior to RFA therapy for single HCC patients without lymph node invasion or distant metastasis. |
