The efficacy and safety of microwave ablation (MWA) compared to radiofrequency ablation (RFA) for patients with treatment-naïve and recurrent hepatocellular carcinoma (HCC) has not been clarified in Korea. There were 150 HCC patients (100 in the RFA group and 50 in the MWA group) enrolled in our study. The primary outcome was one- and two-year disease-free survival (DFS). Secondary outcomes were complete response (CR) rate, two-year survival rate, risk factors for DFS and complication rate. Treatment outcomes were also assessed using propensity-score matching (PSM). The MWA group had better one- and two-year DFS than the RFA group (p = 0.035 and p = 0.032, respectively), whereas the CR rate, two-year survival rate, and complication rate were similar between the two groups with fewer major complications in the MWA group (p = 0.043). Patients with perivascular tumors, high risk of recurrence, and small tumor size (≤3 cm) were more suitable for MWA than RFA. MWA was also an independent factor for favorable one- and two-year DFS. Finally, the MWA group still showed better one- and two-year DFS than the RFA group after PSM. In conclusion, MWA could be an alternative treatment to RFA especially in patients with a high risk of recurrence, perivascular tumors, and small tumor size.

Abstract Background IL34 involves in host immunity regulated carcinogenesis. Alpha-fetoprotein (AFP) is related to the development of HCC. We explored if combination of IL-34 and APF could improve the diagnostic value in HBV related hepatocellular carcinoma (HBVHCC). Methods Serum was obtained from HBV patients or healthy control. Liver tissue was obtained from liver biopsy in CHB, HBV related cirrhosis patients or curative resection in HBVHCC patients. Serum IL34 and MCSF were measured. Hepatic IL34, MCSF and CD68+ tumor associate macrophages (TAMs) were determined. Results Serum IL34 was 1.7, 1.3 or 2.3-fold higher in HBVHCC than that of CHB, HBV related cirrhosis, or healthy control, which was inhibited following transhepatic arterial chemoembolization (TACE) in HBVHCC patients. Intrahepatic IL34 was higher in HBVHCC than that of the other three groups. Intra-hepatic IL34 was associated with high HBVDNA, HBeAg−, poor differentiation and small tumor size of HBVHCC patients. Intra-hepatic TAMs in HBVHCC were increased 1.7 or 1.3-fold, compared to that from CHB or HBV-cirrhosis patients. Intra-hepatic TAMs were associated with high HBVDNA, high tumor differentiation, small tumor size, abnormal AFP and more tumor number. AFP plus serum IL-34, showed the highest AUC (0.837) with sensitivity (0.632) and highest specificity (0.931), suggesting that AFP plus IL-34 enhances the reliability for prediction of the development of HBVHCC among CHB patients. Conclusions Circulating and intra-hepatic IL34 was upregulated gradually in HBV disease progression from CHB, cirrhosis and HCC. IL-34 may be used as a diagnostic biomarker and potential therapeutic target for the management of HBVHCC.

Abstract Background Repeat hepatectomy and radiofrequency ablation (RFA) are widely used to treat early recurrent hepatocellular carcinoma (RHCC) located in the subcapsular region, but the optimal treatment strategy remains to be controversial. Methods A total of 126 RHCC patients in the subcapsular location after initial radical hepatectomy were included in this study between Dec 2014 and Jan 2018. These patients were divided into the RFA group (46 cases) and the repeat hepatectomy group (80 cases). The primary endpoints include repeat recurrence-free survival (rRFS) and overall survival (OS), and the secondary endpoint was complications. The propensity-score matching (PSM) was conducted to minimize the bias. Complications were evaluated using the Clavien-Dindo classification, and severe complications were defined as classification of complications of ≥grade 3. Results There were no significant differences in the incidence of severe complications were observed between RFA group and repeat hepatectomy group in rRFS and OS both before (1-, 2-, and 3-year rRFS rates were 65.2%, 47.5%, and 33.3% vs 72.5%, 51.2%, and 39.2%, respectively, P = 0.48; 1-, 2-, and 3-year OS rates were 93.5%, 80.2%, and 67.9% vs 93.7%, 75.8%, and 64.2%, respectively, P = 0.92) and after PSM (1-, 2-, and 3-year rRFS rates were 68.6%, 51.0%, and 34.0% vs 71.4%, 42.9%, and 32.3%, respectively, P = 0.78; 1-, 2-, and 3-year OS rates were 94.3%, 82.9%, and 71.4% vs 88.6%, 73.8%, and 59.0%, respectively, P = 0.36). Moreover, no significant differences in the incidence of severe complications were observed between the RFA group and repeat hepatectomy group. Conclusion Both repeat hepatectomy and RFA are shown to be effective and safe for the treatment of RHCC located in the subcapsular region.

BackgroundThe purpose of this study was to compare the efficacy and safety of transarterial chemoembolization (TACE) in combination with radiofrequency ablation (RFA) (TACE-RFA) and repeat hepatectomy in the treatment of recurrent hepatocellular carcinoma (HCC) after curative resection.MethodsThis retrospective study evaluated consecutive medical records of patients who received either TACE-RFA or repeat hepatectomy between January 2010 and May 2021. Overall survival (OS), progression-free survival (PFS), and complications were compared.ResultsOf the 2672 patients who received either TACE-RFA or repeat hepatectomy, 111 eligible patients were included in our study, 63 in the TACE-RFA group and 48 in the repeat hepatectomy group. The median OS was 38 months in the TACE-RFA group and 42 months in the repeat hepatectomy group, with no statistically difference between the two groups (P=0.45). Meanwhile, there was also no statistically significant difference in PFS between the two groups (P=0.634). Although both groups achieved similar outcomes, the rate of major complications was significantly higher in the repeat hepatectomy group (P=0.003).ConclusionsPatients with recurrent HCC in the TACE-RFA group and the repeat hepatectomy group had similar OS and PFS regardless of the patient’s tumor diameter, but the TACE-RFA group was safer and more minimally invasive.

Hepatectomy is still as the first-line treatment for the early stage HCC, but the complication rate is higher than p-RFA and the overall survival rate is comparable in these two treatments. Therefore, the patients with small single nodular HCCs could get more benefit from p-RFA, and we need to do further research about p-RFA.
