Objectives: The aim of this study was to compare the clinical effectiveness and cost of percutaneous radiofrequency ablation (PRFA) and surgical resection (SRS) for the management of early stage Hepatocellular Carcinoma.Methods: A systematic literature search of articles in English, French, and Chinese was performed using online databases. Only articles with patients classified as Child-Pugh Class A or B, with tumor size <5 cm were included. A meta-analysis was carried out to estimate the survival rate and disease-free survival rate following PRFA or SRS treatments. The cost of each treatment was estimated from the third party perspective. Univariate sensitivity analyses were used to study the relative importance of each component cost.Results: We identified six studies (one randomized controlled trial (RCT) and five comparative cohort studies) meeting our inclusion criteria. There is good evidence that among Child-Pugh A patients for whom both SRS and PRFA are available options, survival rates following either procedure are comparable, while complications are more frequent and hospitalization longer following SRS. The evidence concerning recurrence rates and disease-free survival is less clear. Whereas the RCT indicates comparable outcomes with either procedure up to 3 years, the results of five cohort studies (with possible selection bias), particularly those with a mix of Child-Pugh A and B patients, favor the surgical option. SRS, costs approximately Canadian $8,275 more per case than PRFA.Conclusions: Continuing doubts on this issue can only be resolved by a substantial RCT. Meanwhile, for early stage HCC patients classified as Child-Pugh A, who despite a possibly higher recurrence rate, prefer the less invasive PRFA to open surgery with its attendant risks, there is sufficient evidence to justify such a choice. For those classified as Child-Pugh (B) it is possible that overall survival is equally good with PRFA, but the evidence is less certain.

AbstractDestroying the hepatic tumor located close to the large vessels is a major limiting factor of radiofrequency ablation (RFA) that is difficult to overcome. A long-term disease-free survival after combined hepatectomy and radiofrequency ablation of a large hepatic tumor adjacent to vena cava has not been previously published. We report a patient with a 23-cm large hepatocellular carcinoma occupying the left lateral segments and a 6-cm contralateral intrahepatic metastasis in Couinaud segments VII–VIII adjacent to the retrohepatic IVC, treated with a combination of resection of the larger tumor and intraoperative radiofrequency ablation of the paracaval tumor under intermittent total vascular exclusion of the right hemiliver. After five years of follow up the patient is disease free. This case demonstrates the importance of vascular control for eliminating the heat sink effect of caval blood flow during RFA of liver tumors adjacent to inferior vena cava.

Abstract Background Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an infrequent type of primary liver cancer that comprises hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). This study investigated the clinicopathological features and prognosis among cHCC-CC, HCC, and CC groups. Methods We prospectively collected the data of 608 patients who underwent surgical resection for liver cancer between 2011 and 2018 at E-Da Hospital, I-Shou University, Kaohsiung, Taiwan. Overall, 505 patients with cHCC-CC, HCC, and CC were included, and their clinicopathological features, overall survival (OS), and recurrence were recorded. OS and recurrence rates were analyzed using the Kaplan–Meier analysis. Results In the entire cohort, the median age was 61 years and 80% were men. Thirty-five (7.0%) had cHCC-CC, 419 (82.9%) had HCC, and 51 (10.1%) had CC. The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. OS was significantly lower in the cHCC-CC group than in the HCC group but was not significantly higher in the cHCC-CC group than in the CC group. The median OS of cHCC-CC, HCC, and CC groups was 50.1 months [95% confidence interval (CI): 38.7–61.2], 62.3 months (CI: 42.1–72.9), and 36.2 months (CI: 15.4–56.5), respectively. Cumulative OS rates at 1, 3, and 5 years in cHCC-CC, HCC, and CC groups were 88.5%, 62.2%, and 44.0%; 91.2%, 76.1%, and 68.0%; and 72.0%, 48.1%, and 34.5%, respectively. After propensity score matching (PSM), OS in the cHCC-CC group was not significantly different from that in the HCC or CC group. However, OS was significantly higher in the HCC group than in the CC group before and after PSM. Furthermore, the disease-free survival was not significantly different among cHCC-CC, HCC, and CC groups before and after PSM. Conclusion The clinicopathological features of the cHCC-CC group were more identical to those of the HCC group than the CC group. The OS rate was significantly lower in the cHCC-CC group than the HCC group. However, after PSM, OS and disease-free survival in the cHCC-CC group were not significantly different from those in the HCC or CC group.

Second-generation radiofrequency ablation (RFA) probes and their successors have more power, shorter ablation times, and an increased area of ablation compared with the first-generation probes used before 2000. We examined whether the use of the newer probes has improved the clinical outcome of RFA for hepatic metastases of colorectal cancer at our tertiary cancer center. Of 160 patients who underwent RFA between 1997 and 2003, 52 had metastases confined to the liver: 21 patients underwent 46 ablations with the first-generation probes and 31 patients underwent 58 ablations with the newer probes. The two groups had similar demographic characteristics. At a median follow-up of 26.2 months, patients treated with the newer probes had a longer median disease-free survival (16 months vs 8 months, P < 0.01) and a lower rate of margin recurrence (5.2% vs 17.4%); eight patients had no evidence of disease and one patient was alive with disease. By contrast, of the 46 patients treated with the first-generation probes, 2 patients had no evidence of disease and 1 patient was alive with disease. Newer-generation probes are associated with lower rates of margin recurrence and higher rates of disease-free survival after RFA of hepatic metastases from colorectal cancer.
