Abstract
BACKGROUND The approach in small hepatocellular carcinoma (HCC) is controversial, no prospective randomized trials to compare ablative or surgical approaches. We compared the surgical and oncological outcomes after laparoscopic hepatectomy (LH) and radiofrequency ablation (RFA) in small HCC patients based on matched cohort studies that performed propensity score matching (PSM). METHODS We systemically searched the PubMed, Cochrane Library, Embase, Web of Science, and the Chinese BioMedical Literature (CBM) databases. All published propensity score-matched studies that compared LH and RFA for small HCC were included in this study. RESULTS Eight studies with a total of 1273 small HCC cases were included. The results of the meta-analysis revealed that there was no significant difference in the 1- year overall survival (OS) rate between the two groups, whereas the LH group had significantly higher 3- year overall survival rate (RR = 1.14, 95% CI 1.08-1.20, p < 0.00001) as well as 1- and 3-year disease-free survival (DFS) rates (RR = 1.31, 95% CI 1.22-1.42, p < 0.00001; RR = 1.66, 95% CI 1.46-1.90, p < 0.00001) than the RFA group. Meanwhile, the local recurrence rate and intrahepatic distant recurrence rate were significantly lower in the LH group than in the RFA group (RR = 0.29, 95% CI 0.20-0.42, p < 0.00001; RR = 0.67, 95% CI 0.49-0.92, p = 0.01). In comparison with the LH group, the RFA group had a lower incidence of overall and major postoperative complications (RR = 1.81, 95% CI 1.47-2.24, p < 0.00001; RR = 2.76, 95% CI 1.48-5.12, p = 0.001), but there was no significant difference in postoperative mortality between the two groups. In addition, further comparison of single postoperative complications showed that the incidence of ascites was lower in the RFA group than in the LH group (RR = 3.62, 95% CI 1.64-7.96, p = 0.001), whereas there was no significant difference in the incidence of postoperative bleeding, abdominal infection and bile leakage between the two groups (RR = 3.50, 95% CI 0.74-16.61, p = 0.11; RR = 5.00, 95% CI 0.59-42.23, p = 0.14; RR = 4.00, 95% CI 0.45-35.23, p = 0.21). Besides, the hospital stay was shorter in the RFA group than in the LH group (MD = 4.29, 95% CI 2.06-6.53, p = 0.0002). CONCLUSIONS Our meta-analysis demonstrated that in comparison with RFA in the treatment of small HCC, LH provided superior long-term OS and DFS together with lower rates of local and intrahepatic distant recurrence after surgery. However, RFA was associated with better short-term outcomes.

Abstract
AIM The purpose of this study was to compare the long-term outcomes of laparoscopic hepatectomy (LH) and percutaneous radiofrequency ablation (PRFA) for the treatment of small hepatocellular carcinoma. METHODS We systematically searched PubMed, Embase, Web of Science, and Medline from January 2000 to May 2022 for literature comparing the efficacy of LH and PRFA in the treatment of small hepatocellular carcinoma (largest tumour diameter ≤ 3 cm, number of intrahepatic tumours ≤3, or diameter of a single intrahepatic lesion ≤5 cm. ). We assessed overall survival (OS), recurrence-free survival (RFS), local recurrence and complication rates. RESULTS A total of 1886 patients with small HCC were included in the 8 studies included in this study, of which 839 underwent LH and 1047 underwent PRAF. The results of the meta-analysis showed that the two groups had the same 3-year (HR: 0.99, 95% CI: 0.67 to 1.47) and 5-year (HR: 1.30, 95% CI: 0.90 to 1.87) OS rates, and the LH group had better 3-year (HR: 0.58, 95% CI: 0.49 to 0.68) and 5-year (HR: 0.56, 95% CI: 0.37 to 0.85) RFS rates. The LH group had a lower local recurrence rate (OR: 0.19, 95% CI: 0.12 to 0.32), but the PRFA group had a lower complication rate (OR: 2.49, 95% CI: 1.76 to 3.54). CONCLUSION There was no difference in OS between LH and PRFA in the treatment of small HCC. LH had a higher RFS rate and a lower local recurrence rate, but PRFA had a lower complication rate. In general, the long-term efficacy of LH in the treatment of small HCC is better than that of PRFA. Considering the advantages of less trauma and a low complication rate of PRFA, a large number of RCT studies are needed for further verification in the future.

Comparison of liver resection and radiofrequency ablation in long-term survival among patients with early-stage hepatocellular carcinoma: a meta-analysis of randomized trials and high-quality propensity score-matched studies. World J Surg Oncol 2024; 22:56. [PMID: 38369480 PMCID: PMC10875898 DOI: 10.1186/s12957-024-03330-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Accepted: 02/02/2024] [Indexed: 02/20/2024] Open
Abstract
BACKGROUND Whether radiofrequency ablation (RFA) and liver resection (LR) are comparable treatments for early-stage hepatocellular carcinoma (HCC) is controversial. We conducted this study to provide ample clinical evidence for the argument. METHODS The PubMed, Embase, Web of Science, and Cochrane Library databases were systematically searched to identify randomized controlled trials (RCTs) and propensity score-matched (PSM) studies that compared long-term outcomes of both RFA and LR for patients with early-stage HCC. The hazard ratios (HRs) with 95% confidence intervals (95% CI) of overall survival (OS) and disease-free survival (DFS) were calculated. RESULTS Thirty-six studies consisting of six RCTs and 30 PSM studies were included in this study, and a total of 7384 patients were involved, with 3694 patients being treated with LR and 3690 patients with RFA. Meta-analysis showed that LR provided better OS and DFS than RFA (HR: 1.22, 95% CI: 1.13-1.31; HR: 1.56, 95% CI: 1.39-1.74, respectively). A sensitivity analysis indicated that the results were stable. For the subgroup of patients with BCLC 0 stage, RFA and LR resulted in similar OS and DFS. For the subgroup of patients with single tumor sizes less than 3 cm, RFA reached similar OS (HR: 1.19, 95% CI: 0.90-1.58) but worse DFS compared with LR (HR: 1.45, 95% CI: 1.11-1.90). For the subgroup of ablation margin larger than 0.5 cm, LR still resulted in better OS than RFA (HR: 1.29, 95% CI: 1.09-1.53); while the ablation margin was larger than 1 cm, both RFA and LR resulted in similar OS. The modality of RFA was also a factor that affected results. Subgroup analysis showed that patients receiving ultrasound-guided RFA had worse OS and DFS than LR (HR: 1.24, 95% CI: 1.14-1.36; HR: 1.44, 95% CI: 1.25-1.66, respectively). CONCLUSIONS Meta-analysis showed that LR provided better OS and DFS for patients with early-stage HCC. However, RFA and LR had similar effects on long-term survival in patients with BCLC 0 stage HCC. RFA and LR probably had similar effects on OS in patients with solitary HCC less than 3 cm or when the ablation margin was larger than 1 cm which need more studies to confirm. The effects of different modalities of RFA on long-term survival are needed for further assessment.

Efficacy and safety of laparoscopic liver resection versus radiofrequency ablation in patients with early and small hepatocellular carcinoma: an updated meta-analysis and meta-regression of observational studies. World J Surg Oncol 2024; 22:47. [PMID: 38326841 PMCID: PMC10848480 DOI: 10.1186/s12957-023-03292-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 12/26/2023] [Indexed: 02/09/2024] Open
Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most common type of liver cancer, accounting for 90% of cases worldwide and a significant contributor to cancer-related deaths. This study comprehensively compares the safety and efficacy of laparoscopic liver resection (LLR) versus laparoscopic or percutaneous radiofrequency ablation (LRFA or PRFA) in patients with early and small HCC. METHODS We systematically searched Cochrane Library, PubMed, Scopus, and Web of Science databases to include studies comparing LLR versus LRFA or PRFA in patients with early HCC meets the Milan criteria (defined as solitary nodule < 5 cm or three nodules ≤ 3 cm with no extrahepatic spread or vascular invasion). Pooled results were examined for overall survival, disease-free survival, recurrence-free survival, local, intrahepatic and extrahepatic recurrence rates, and complications. We conducted subgroup analyses based on the type of RFA. Meta-regression analyzed the association between overall survival, local recurrence, and various factors. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. We analyzed the data using the R (v.4.3.0) programming language and the "meta" package of RStudio software. RESULTS We included 19 observational studies, compromising 3756 patients. LLR showed higher 5-year overall survival compared to RFA (RR = 1.17, 95% CI [1.06, 1.3], P > 0.01). Our subgroup analysis showed that LLR had higher 5-year survival than PRFA (RR = 1.15, 95% CI [1.02, 1.31], P = 0.03); however, there was no significant difference between LLR and LRFA (RR = 1.26, 95% CI [0.98, 1.63], P = 0.07). LLR was associated with higher disease-free survival) RR = 1.19, 95% CI [1.05, 1.35], P < 0.01; RR = 1.61, 95% CI [1.31, 1.98], P < 0.01(and recurrence-free survival) RR = 1.21, 95% CI [1.09, 1.35], P < 0.01; RR = 1.45, 95% CI [1.15, 1.84], P < 0.01(at 1 and 3 years. LLR was associated with lower local (RR = 0.28, 95% CI [0.16, 0.47], P < 0.01) and intrahepatic recurrence (RR = 0.7, 95% CI [0.5, 0.97], P = 0.03) than RFA. However, complications were significantly higher with LLR (RR = 2.01, 95% CI [1.51, 2.68], P < 0.01). Our meta-regression analysis showed that younger patients had higher risk for local recurrence (P = 0.008), while age wasn't significantly linked to overall survival (P = 0.25). Other covariates like total bilirubin, alpha-fetoprotein levels, and tumor size also showed no significant associations with either overall survival or local recurrence. CONCLUSION LLR offers improved long-term outcomes and lower recurrence rates than PRFA. However, no significant distinctions were observed between LRFA and LLR in overall survival, recurrence-free survival, and local recurrence. More robust well-designed RCTs are essential to validate our findings.

Abstract
Worldwide, hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death. The remarkable improvements in treating HCC achieved in the last years have increased the complexity of HCC management. Following the need to have updated guidelines on the multidisciplinary treatment management of HCC, the Italian Scientific Societies involved in the management of this cancer have promoted the drafting of a new dedicated document. This document was drawn up according to the GRADE methodology needed to produce guidelines based on evidence. Here is presented the first part of guidelines, focused on the multidisciplinary tumor board of experts and surgical treatments of HCC.

Abstract
Background A wide range of ablative and non-surgical therapies are available for treating small hepatocellular carcinoma in patients with very early or early-stage disease and preserved liver function. Objective To review and compare the effectiveness of all current ablative and non-surgical therapies for patients with small hepatocellular carcinoma (≤ 3 cm). Design Systematic review and network meta-analysis. Data sources Nine databases (March 2021), two trial registries (April 2021) and reference lists of relevant systematic reviews. Review methods Eligible studies were randomised controlled trials of ablative and non-surgical therapies, versus any comparator, for small hepatocellular carcinoma. Randomised controlled trials were quality assessed using the Cochrane Risk of Bias 2 tool and mapped. The comparative effectiveness of therapies was assessed using network meta-analysis. A threshold analysis was used to identify which comparisons were sensitive to potential changes in the evidence. Where comparisons based on randomised controlled trial evidence were not robust or no randomised controlled trials were identified, a targeted systematic review of non-randomised, prospective comparative studies provided additional data for repeat network meta-analysis and threshold analysis. The feasibility of undertaking economic modelling was explored. A workshop with patients and clinicians was held to discuss the findings and identify key priorities for future research. Results Thirty-seven randomised controlled trials (with over 3700 relevant patients) were included in the review. The majority were conducted in China or Japan and most had a high risk of bias or some risk of bias concerns. The results of the network meta-analysis were uncertain for most comparisons. There was evidence that percutaneous ethanol injection is inferior to radiofrequency ablation for overall survival (hazard ratio 1.45, 95% credible interval 1.16 to 1.82), progression-free survival (hazard ratio 1.36, 95% credible interval 1.11 to 1.67), overall recurrence (relative risk 1.19, 95% credible interval 1.02 to 1.39) and local recurrence (relative risk 1.80, 95% credible interval 1.19 to 2.71). Percutaneous acid injection was also inferior to radiofrequency ablation for progression-free survival (hazard ratio 1.63, 95% credible interval 1.05 to 2.51). Threshold analysis showed that further evidence could plausibly change the result for some comparisons. Fourteen eligible non-randomised studies were identified (n ≥ 2316); twelve had a high risk of bias so were not included in updated network meta-analyses. Additional non-randomised data, made available by a clinical advisor, were also included (n = 303). There remained a high level of uncertainty in treatment rankings after the network meta-analyses were updated. However, the updated analyses suggested that microwave ablation and resection are superior to percutaneous ethanol injection and percutaneous acid injection for some outcomes. Further research on stereotactic ablative radiotherapy was recommended at the workshop, although it is only appropriate for certain patient subgroups, limiting opportunities for adequately powered trials. Limitations Many studies were small and of poor quality. No comparative studies were found for some therapies. Conclusions The existing evidence base has limitations; the uptake of specific ablative therapies in the United Kingdom appears to be based more on technological advancements and ease of use than strong evidence of clinical effectiveness. However, there is evidence that percutaneous ethanol injection and percutaneous acid injection are inferior to radiofrequency ablation, microwave ablation and resection.

Abstract
ObjectiveTo compare the efficacy of liver resection (LR), radiofrequency ablation (RFA), and radiofrequency ablation combined with transcatheter arterial chemoembolization (RFA+TACE) in the treatment of very-early- and early-stage hepatocellular carcinoma (HCC).MethodsWe systemically searched the PubMed, Embase, and Cochrane Library databases. Randomized controlled trials (RCTs) and observational analyses with propensity score-matched cohort analyses (PSMs) comparing any two of the three treatments were included in this study. The primary result was overall survival (OS) and the secondary result was recurrence-free survival (RFS), which were analyzed by calculating the hazard ratio (HR) and 95% confidence intervals (CI).ResultsA total of 25 studies (4249 patients), including 10 RCTs and 15 PSM observational studies, met the inclusion criteria. Although there was no significant difference between LR and RFA in terms of one-year OS, though LR showed superior performance for three- and five-year OS (at three years, HR: 0.74, 95% CI: 0.56-0.96; at five years, HR: 0.73, 95% CI: 0.55-0.94). In addition, significantly higher rates of RFS at one-, three- and five-year follow-up were found for LR than for RFA alone (at one year, HR: 0.68, 95% CI: 0.51-0.92; at three years, HR: 0.67, 95% CI: 0.55-0.81; at five years, HR: 0.61, 95% CI: 0.48-0.78). The combination of RFA+TACE was superior to RFA alone based on one-year RFS (HR: 0.57, 95% CI: 0.34-0.96), while there were no significant differences in OS at one, three, and five years, and in RFS at three and five years.ConclusionsFor very-early- and early-stage HCC, this systematic review and network meta-analysis showed that the efficacy of LR is superior to that of RFA alone, regardless of whether the evaluation is based on either OS or RFS. The advantages of RFA+TACE compared to RFA alone are limited, and further studies are needed to determine whether combination therapy is necessary, i.e., results in significantly improved outcomes.

Anatomic resection versus radiofrequency ablation with an ablative margin ≥ 1.0 cm for solitary small hepatocellular carcinoma measuring ≤ 3 cm: Comparison of long-term outcomes using propensity score matching analysis. Eur J Radiol 2022; 155:110498. [PMID: 36049409 DOI: 10.1016/j.ejrad.2022.110498] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 07/17/2022] [Accepted: 08/20/2022] [Indexed: 02/07/2023]
Abstract
PURPOSE To compare the long-term outcomes of anatomic resection (AR) and radiofrequency ablation (RFA) with an ablative margin (AM) of ≥ 1.0 cm as first-line treatment for solitary hepatocellular carcinoma measuring ≤ 3 cm. METHODS Two hundred and fifty-one patients who underwent AR (n = 156) or RFA (ablative margin ≥ 1.0 cm, n = 95) at any of 6 tertiary hospitals from 2009 to 2018 were enrolled. Propensity score matched analysis (PSM) were used to compare overall survival (OS), recurrence-free survival (RFS), and perioperative outcomes. Univariate and multivariate analyses were performed to identify prognostic factors associated with RFS and OS. RESULTS PSM created 67 patient-pairs. After 96 months of follow-up, RFA with an ablative margin ≥ 1.0 cm and AR showed comparable 1-year, 3-year, 5-year, and 8-year OS rates before (P = 0.580) and after (P = 0.640) PSM. However, RFS was better at 1, 3, 5, and 8 years after AR before (P = 0.0036) and after (P = 0.017) PSM. The operation time and postoperative hospital stay were significantly longer in the AR group than in the RFA group before and after PSM (P < 0.05). Multivariate analysis identified age and type of treatment to be independent prognostic factors for RFS and age and hepatitis C to be associated with OS. CONCLUSIONS Long-term OS was not significantly different between AR and RFA with an AM ≥ 1.0 cm in patients with a solitary hepatocellular carcinoma measuring ≤ 3 cm; but, RFS appeared to be better after AR than after RFA. However, RFA was associated with fewer perioperative complications and a shorter postoperative hospital stay.

A study of the causes and classification of local tumour progression. Eur Radiol 2022; 32:8518-8526. [PMID: 35704110 DOI: 10.1007/s00330-022-08913-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 05/26/2022] [Accepted: 05/30/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVES Local tumour progression (LTP) is believed to be a negative consequence of imperfect thermal ablation, but we wondered if all LTP is truly due to imperfect ablation. METHODS This study included 185 LTPs occurring within 1 cm of the ablation zone (AZ) after clinical curative thermal ablation for ≤ 5 cm hepatocellular carcinoma between 2010 and 2019. The AZ was divided into 8 quadrants by coronal, sagittal, and horizontal planes. Two methods, visual assessment through pre- and post-MRI (VA) and tumour mapping for 3D visualisation pre- and post-MRI fusion (MF), were used to assess which AZ quadrant included the shortest ablation margin (AM) by three doctors. LTP subclassification was based on whether LTP contacted the AZ margin (contacted LTP and dissociated-type LTP) and occurrence at different time points (12, 18, and 24 months). RESULTS Fleiss's Kappa of VA and MF was 0.769 and 0.886, respectively. Cohen's Kappa coefficient between VA and MF was 0.830. For all LTPs, 98/185 (53.0%) occurred in the shortest AM quadrant, which showed a significant central tendency (p < 0.001). However, only 8/51 (15.7%) dissociated - type LTPs and 6/39 (15.4%) LTPs after 24 months occurred in the shortest AM quadrant, which showed no evenly distributed difference (p = 0.360 and 0.303). CONCLUSIONS MF is an accurate and convenient method to assess the shortest AM quadrant. LTP is a central tendency in the shortest AM quadrant, but dissociated-type and LTPs after 24 months are not, and these LTP types could be considered nonablation-related LTPs. KEY POINTS • LTPs are not evenly distributed around the AZ. More than half of LTPs occur in the shortest AM quadrant. • Subgroup analysis showed that the occurrence of contacted-type LTPs (tumour margin has direct contact with the AZ) within 24 months after ablation indeed had a high proportion in the shortest AM quadrant, and they could be called ablation-related LTPs. • However, the dissociated-type LTPs (tumour margin adjacent to but not in contact with the AZ) or LTPs occurring beyond 24 months after ablation were evenly distributed around the AZ, and they could be called nonablation-related LTPs.

Prognostic Role of Albumin-Bilirubin Grade in Hepatocellular Carcinoma After Ultrasound-guided Percutaneous Radiofrequency Ablation: A Single-center Experience Over a Decade. Surg Laparosc Endosc Percutan Tech 2022; 32:350-356.

Abstract
BACKGROUND The albumin-bilirubin (ALBI) grade has been proposed to evaluate liver function and predict prognosis in patients with hepatocellular carcinoma (HCC). Data are scarce in terms of the clinical application of ALBI score in patients with HCC undergoing radiofrequency ablation (RFA). The current study sought to assess the prognostic efficacy of ALBI grade in early-stage HCC after RFA. METHODS We retrospectively reviewed 344 treatment-naive patients, whereby the overall survival (OS), recurrence-free survival (RFS), local tumor progression, and intrahepatic distant recurrence were assessed using Kaplan-Meier analysis. Predictors determining OS and RFS after RFA were analyzed using Cox proportional hazards analysis. RESULTS During a median follow-up time of 48.0 months (range: 2 to 158 mo), 48 patients had died because of tumor progression or liver failure. Patients with ALBI grade 2 had poorer OS (P=0.033) and RFS (P=0.002), and higher intrahepatic distant recurrence rate (P<0.001) than those with ALBI grade 1. Local tumor progression rates were comparable between the 2 groups (P=0.801). Multivariate analyses showed that ABLI grade 2 was the only independent risk factor for poor OS (hazard ratio=1.850, 95% confidence interval: 1.041-3.286, P=0.036) and poor RFS (hazard ratio=1.467, 95% confidence interval: 1.094-1.968, P=0.011) after RFA. For Child-Pugh grade A group, patients divided by ALBI grade 1 versus grade 2 showed significant differences in both OS and RFS (P=0.039 and 0.002). CONCLUSION The ALBI grade can be used to discriminate long-term prognosis in patients with HCC following RFA and to further stratify prognosis in those with Child-Pugh grade A.

Minimally invasive surgery versus percutaneous radiofrequency ablation for early-stage hepatocellular carcinoma: Results from a high-volume liver surgery center in East Asia. Surg Oncol 2022; 42:101769. [PMID: 35468499 DOI: 10.1016/j.suronc.2022.101769] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 03/07/2022] [Accepted: 04/10/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS The outcomes of minimally invasive surgery (MIS) vs. percutaneous radiofrequency ablation (RFA) in treating early-stage hepatocellular carcinoma (HCC) remain inconclusive. This study thus aimed to compare the outcomes of both treatments for early-stage HCCs. METHODS This retrospective study consecutively enrolled patients with newly diagnosed early-stage HCCs treated with MIS or percutaneous RFA between 2011 and 2018. Outcomes were compared between the MIS and RFA groups both before and after 1:1 propensity score matching (PSM). RESULTS A total of 119 and 481 patients underwent MIS and percutaneous RFA, respectively. Patients undergoing percutaneous RFA exhibited older age (p = 0.007) and higher rates of Child-Pugh class B (p < 0.001) and multifocal disease (p < 0.001). The median overall survival (OS) was 73.7 months in the MIS group, which was significantly higher than that for the RFA group of 65.1 months (p = 0.003). 50% HCC recurrence after MIS was not reached. The mean recurrence-free survival (RFS) was 49.6 months for the MIS group, which was significantly higher than the RFA group of 41.3 months (p < 0.001). On multivariate analysis, age ≥65 (HR: 1.61; 95% CI: 1.13-2.31, p = 0.009), RFA (HR: 2.21; 95% CI: 1.14-4.29, p = 0.019), and Child-Pugh class B (HR: 2.03; 95% CI: 1.29-3.21, p = 0.002) remained risk factors for OS, and RFA (HR: 2.18; 95% CI: 1.42-3.35; p < 0.001) remained a risk factor for RFS. After PSM, 103 patients were included in each group. No significant difference in OS was identified (p = 0.198), but RFS was higher in the MIS group than the RFA group (p = 0.003). Severe postoperative complications occurred at the same rate (1%) in both groups (p > 0.99). CONCLUSION After PSM, severe postoperative complication and OS rates were found to be comparable between the MIS and RFA groups, but RFS was higher in the MIS group than the RFA group, suggesting that MIS may have better outcomes for patients with early-stage HCC.

Abstract
BACKGROUND Both microwave ablation and robot-assisted hepatectomy are representative minimally invasive treatments for early hepatocellular carcinoma. Our study compares the practicability and medium-term therapeutic efficacy between them. METHODS Patients with early HCC treated by MWA or RH from 2013 to 2019 were included. Propensity score matching (PSM) and inverse probability of treatment weight (IPTW) were used to minimize baseline imbalance. Operation trauma, postoperative recovery, complications, cost and oncological efficacy were compared. RESULTS 401 patients with a median follow-up of 28 months were included (MWA n = 240; RH n = 161). After PSM, 3-year recurrence-free survival (RFS), overall survival (OS) and cancer-specific survival (CSS) of MWA group and RH group were 52.2% vs 65.8%, 91.5% vs 91.3% and 91.5% vs 91.3%, respectively. OS and CSS were comparable (p = 0.44 and 0.96), while RFS of MWA was slightly lower but not significant (p = 0.097). The above results after IPTW followed the same trend. After PSM, MWA showed advantages in operation time and blood loss, while RH performed better in postoperative liver function. There was no significant difference in incidence of severe complications between two groups. CONCLUSIONS For early HCC parents, both treatments can achieve good, safe and comparable medium-term therapeutic effects. MWA is more minimally invasive, while RH has better accuracy and causes less damage to liver parenchyma.

Abstract
BACKGROUND Tumor recurrence is an abomination for hepatocellular carcinoma (HCC) patients receiving local treatment. PURPOSE The aim of the study was to build a hybrid machine learning model to recommend optimized first treatment (laparoscopic hepatectomy [LH] or microwave ablation [MWA]) for naïve single 3-5-cm HCC patients based on early recurrence (ER, ≤2 years) probability. METHODS This retrospective study collected 20 semantic variables of 582 patients (LH: 300, MWA: 282) from 13 hospitals with at least 24 months follow-up. Both groups were divided into training, validation, and test set, respectively. Five algorithms (logistics regression, random forest, neural network, stochastic gradient boosting, and eXtreme Gradient Boosting [XGB]) were used for model building. A model with highest area under the receiver operating characteristic curve (AUC) in a validation set of LH and MWA was selected to connect as a hybrid model which made decision based on ER probability. Model testing was performed in a comprehensive set comprising LH and MWA test sets. RESULTS Four variables in each group were selected to build LH and MWA models, respectively. LH-XGB model (AUC = 0.744) and MWA-stochastic gradient method (AUC = 0.750) model were selected for model building. In the comprehensive set, a treatment confusion matrix was established based on recommended and actual treatment. The predicted ER probabilities were comparable with the actual ER rates for various types of patients in matrix (p > 0.05). ER rate of patients whose actual treatment consistent with recommendation was lower than that of inconsistent patients (LH: 21.2% vs. 46.2%, p = 0.042; MWA: 26.3% vs. 54.1%, p = 0.048). By recommending optimal treatment, the hybrid model can significantly reduce ER probability from 38.2% to 25.6% for overall patients (p < 0.001). CONCLUSIONS The hybrid model can accurately predict ER probability of different treatments and thereby provide reliable evidence to make optimal treatment decision for patients with single 3-5-cm HCC.

Abstract
With the improvement of technology and diagnostic level, radiofrequency ablation (RFA) has made rapid progress in the treatment of primary hepatocellular carcinoma (HCC) in the past two decades. Especially, the overall survival after the treatment of small HCCs by RFA can be comparable to that achieved by hepatic resection. The 10-year survival rates of RFA for HCC were 27.3%-46.1%, and for solitary HCC less than 3 cm, the 10-year survival rate is about 74.0%. RFA combined with other therapies can expand the indications of RFA treatment and benefit the survival of patients with HCC. The prognostic model of RFA for HCC provides a powerful tool for individualized clinical diagnosis and treatment.

Abstract
Real-world evidence includes all health-related information, such as electronic health records, insurance claims, pharmacy records and wearables that are obtained outside of clinical trials. These data can provide critical insights into the natural history of disease and evaluate the safety and effectiveness of treatment regimens used in clinical practice. Real-world data have been applied to varying degrees by global regulatory agencies to inform and expedite many phases of drug development and help refine the use of therapeutic regimens after marketing, especially in populations that are under-represented in registration trials. For the management of hepatocellular carcinoma, early detection provides the best chance for curative therapies, whose success has been evaluated in numerous cohorts. The availability of novel systemic therapies, including kinase inhibitors and immunotherapies, has provided new treatment options and improved survival in patients with advanced stage hepatocellular carcinoma. Real-world longitudinal observational studies can help understand the long-term safety and effectiveness of these agents.

Abstract
OBJECTIVE To compare the oncologic outcomes of liver resection (LR) and local ablation therapies for HCC. SUMMARY OF BACKGROUND DATA Although several studies have compared LR and local ablation therapies, the optimal treatment of choice for HCC within the Milan criteria remains controversial. METHODS We systemically searched the MEDLINE, Embase, and Cochrane Library databases for randomized control trials (RCTs) and matched nonrandomized trials (NRTs) that compared LR and local ablation therapies for HCC within the Milan criteria. The primary outcome was overall survival (OS). Secondary outcomes were recurrence free survival (RFS) and recurrence pattern. RESULTS A total of 7 RCTs and 18 matched NRTs, involving 2865 patients in the LR group and 2764 patients in the local ablation therapy group [RFA, MWA, RFA plus trans-arterial chemoembolization (TACE)], were included. Although there was no significant difference in OS between LR and RFA, LR showed a significantly better 5-year RFS than RFA in the analysis of RCTs (hazards ratio: 0.75; 95% confidence interval: 0.62-0.92; P = 0.006). The RFA group showed a significantly higher local recurrence than the LR group in both analyses of RCTs and NRTs. Additionally, the LR group showed better OS and RFS than the MWA or RFA plus TACE groups. CONCLUSION Our meta-analysis showed that LR was superior to RFA in terms of RFS and incidence of local recurrence. Moreover, LR showed better oncologic outcomes than MWA or RFA plus TACE.

Front Med (Lausanne) 2020; 7:139. [PMID: 32478080 PMCID: PMC7232563 DOI: 10.3389/fmed.2020.00139] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Accepted: 03/30/2020] [Indexed: 12/11/2022] Open
Abstract
Aim: The influence of surgical margin on the prognosis of patients with early solitary hepatocellular carcinoma (HCC) (≤5 cm) is undetermined. Methods: The data of 904 patients with early solitary HCC who underwent liver resection were collected for recurrence-free survival (RFS) and overall survival (OS). Propensity score matching (PSM) was performed to balance the potential bias. Results: Log-rank tests showed that 2 mm was the best cutoff value to discriminate the prognosis of early HCC. Liver resection with a >2 mm surgical margin distance (wide-margin group) led to better 5-year RFS and OS rate compared with liver resection with a ≤2 mm surgical margin distance (narrow-margin group) among patients both before (RFS: 59.1% vs. 39.6%, P < 0.001; OS: 85.3% vs. 73.7%, P < 0.001) and after PSM (RFS: 56.3% vs. 41.0%, P < 0.001; OS: 83.0% vs. 75.0%, P = 0.010). Subgroup analysis showed that a wide-margin resection significantly improved the prognosis of patients with microvascular invasion (RFS: P < 0.001; OS: P = 0.001) and patients without liver cirrhosis (RFS: P < 0.001; OS: P = 0.001) after PSM. Multivariable Cox regression analysis revealed that narrow-margin resection is associated with poorer RFS [hazard ratio (HR) = 1.781, P < 0.001), OS (HR = 1.935, P < 0.001], and early recurrence (HR = 1.925, P < 0.001). Conclusions: A wide-margin resection resulted in better clinical outcomes than a narrow-margin resection among patients with early solitary HCC, especially for those with microvascular invasion and without cirrhosis. An individual strategy of surgical margin should be formulated preoperation according to both tumor factors and background liver factors.
