Local recurrence risk factors and outcomes in minimally invasive thermal ablation for liver tumors: a single-institution analysis. HPB (Oxford) 2024; 26:682-690. [PMID: 38342647 DOI: 10.1016/j.hpb.2024.01.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 12/27/2023] [Accepted: 01/26/2024] [Indexed: 02/13/2024]
Abstract
BACKGROUND Minimally Invasive thermal ablation (MITA) of liver tumors is a commonly performed procedure, alone or in combination with liver resection. Despite being a first-option strategy for small lesions, it is technically demanding, and many concerns still exist about local disease control. METHODS Consecutive patients undergoing MITA from 1-2019 to 12-2022 were retrospectively enrolled. Risk factors of local recurrence were investigated through univariate and multivariable cox regression analysis. RESULTS At the multivariable analysis of the 207 nodules undergoing MITA, RFA was associated with worse local Recurrence Free Survival (lRFS) than MWA (HR 2.87 [95 % CI 0.96-8.66], p = 0.05), as well as a concomitant surgical resection (HR 3.89 [95 % CI 1.06-9.77], p = 0.02). A concomitant surgical resection showed worse lRFS in the subgroup analysis of both HCC (HR 3.98 [95 % CI 1.16-13.62], p = 0.02) and CRLM patients (HR 2.68 [95 % CI 0.66-5.92], p = 0.04). Interestingly, a tumor size between 30 and 40 mm was not associated to worse lRFS. CONCLUSION MWA may reduce the risk of local recurrence in comparison to RFA, while MITA associated to liver resection may face an increased risk of local recurrence. Further prospective studies are needed to confirm such results.

Radiofrequency ablation of subcapsular versus nonsubcapsular hepatocellular carcinomas ≤ 3 cm: analysis of long-term outcomes from two large-volume liver centers. Eur Radiol 2024; 34:1578-1586. [PMID: 37646813 DOI: 10.1007/s00330-023-10165-6] [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: 01/04/2023] [Revised: 07/07/2023] [Accepted: 07/20/2023] [Indexed: 09/01/2023]
Abstract
OBJECTIVES To compare the safety and efficacy of RFA for single HCCs ≤ 3 cm in subcapsular versus nonsubcapsular locations using a propensity score matched analysis. MATERIALS AND METHODS This retrospective study included patients with solitary HCCs ≤ 3 cm in size who underwent percutaneous RFA from 2005 to 2015 as initial treatment at two large-volume liver centers. Patients were divided into two groups, consisting of those with subcapsular and nonsubcapsular tumor locations. Complications, local tumor progression (LTP), and overall survival (OS) were compared in these two groups before and after propensity score matching (PSM). RESULTS The study population consisted of 964 patients (712 men [74%]) of mean age 58.3 years. Of these 964 patients, 561 (58%) had nonsubcapsular and 403 (42%) had subcapsular HCCs. PSM generated 402 pairs of patients. Major complication rate was low, but significantly higher in the subcapscular group (p = 0.047). Rates of technical effectiveness in these two groups were 99% and 98%, respectively (p = 0.315). However, during follow-up, cumulative 1-, 3-, 5-, and 10-year LTP and OS rates did significantly differ in both entire and PSM cohorts, resulting in the latter 8%, 15%, 20%, and 26% in the nonsubcapsular group vs. 13%, 24%, 30%, and 31% in the subcapsular group (p = 0.015), and 99%, 91%, 80%, and 59% vs. 98%, 85%, 73%, and 50% in the two groups (p = 0.004), respectively. CONCLUSION Rates of major complications, LTP, and OS differed significantly following first-line RFA treatment of single HCCs ≤ 3 cm in favor of the nonsubcapsular locations. CLINICAL RELEVANCE STATEMENT This large-scale study provides evidence that radiofrequency ablation for small (≤ 3 cm) hepatocellular carcinomas is safer and more effective in nonsubcapsular location than in subcapsular location. KEY POINTS • There exist conflicting outcomes on the effectiveness of RFA for early HCC depending on tumor location. • Rate of local tumor progression was significantly higher in the subcapsular hepatocellular carcinomas. • Overall survival rate was significantly poorer in the subcapsular hepatocellular carcinomas.

Diagn Interv Radiol 2023; 29:819-825. [PMID: 37650514 PMCID: PMC10679561 DOI: 10.4274/dir.2023.232253] [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: 04/17/2023] [Accepted: 08/08/2023] [Indexed: 09/01/2023]
Abstract
PURPOSE To evaluate the safety and efficacy of transcatheter arterial embolization (TAE) in controlling hemodynamically unstable bleeding following a percutaneous transthoracic needle biopsy (PTNB). METHODS A total of seven patients (four men and three women; mean age, 62 ± 12 years) who received TAE for post-PTNB bleeding between May 2007 and March 2022 were included. The observed types of bleeding were hemothorax (n = 3), hemoptysis (n = 2), and a combination of both (n = 2). In patients with active bleeding, the technical success of TAE was defined as superselective embolization of the target artery with no active bleeding visible on post-TAE angiography. Clinical success was defined as sustained cessation of bleeding without hemodynamic instability, requirement of repeat TAE, or the need for post-TAE hemostatic surgery during the initial admission. The metrics analyzed included technical and clinical success rates, complications, and 30-day mortality. RESULTS All seven patients achieved technical success, with a clinical success rate of 86% (6/7). Six patients were discharged alive, while one patient died of respiratory failure accompanied by hemothorax 19 days post-biopsy. The angiographic findings associated with bleeding were contrast media extravasation or pseudoaneurysm (n = 3) and vascular hypertrophy with tortuosity (n = 2). The implicated bleeding arteries included the intercostal artery (n = 2), bronchial artery (n = 2), and internal thoracic artery (n = 1). In two cases, no clear bleeding foci were identified; nonetheless, prophylactic embolization was performed on the right intercostal artery (n = 1) and right intercostobronchial trunk (n = 1). The embolic agents utilized included microcoils (n = 1), gelatin sponge particles (n = 2), polyvinyl alcohol (PVA) with gelatin sponge particles (n = 1), PVA with microcoils (n = 1), microcoils with gelatin sponge particles (n = 1), and microcoils with n-butyl-2-cyanoacrylate and gelatin sponge particles (n = 1). The 30-day mortality rate was 14% (1/7). No ischemic complications related to TAE were observed. CONCLUSION The study suggests that TAE is safe and effective for controlling hemodynamically unstable bleeding following a PTNB.

Abstract
OBJECTIVE To evaluate the hemostatic efficacy of re-radiofrequency ablation (re-RFA) for hepatic tract bleeding after ultrasound-guided RFA of hepatic tumors. METHODS A total of 4679 percutaneous ultrasound-guided RFA procedures were performed for hepatic tumors at Samsung Medical Center between January 2012 and December 2020. We identified patients who had hepatic tract bleeding after RFA by reviewing radiologic reports and ultrasound images and investigated the measures taken to control the bleeding and their outcomes. We also identified patients who had a significant peritoneal hematoma on immediate post-RFA CT or underwent transarterial embolization to control hepatic bleeding after RFA of hepatic tumors. RESULTS In total, 91 patients with tract bleeding after RFA were identified. As initial measures to control the bleeding, external compression, re-RFA, and observation were performed in 71 (78%), 17 (19%), and 3 (3%) patients, respectively. Hemostasis using re-RFA was attempted to control tract bleeding in 40 patients as an initial measure or an additional measure after other initial efforts. In all 40 patients, the bleeding stopped after re-RFA on Doppler ultrasound, and there was no active bleeding on the immediate follow-up CT. During the study period, in the years when re-RFA was performed frequently, the number of transarterial embolizations to control tract bleeding and significant peritoneal hematoma formation tended to be low. CONCLUSION Hemostasis using re-RFA of the needle tract is effective in controlling tract bleeding after ultrasound-guided RFA of hepatic tumors. ADVANCES IN KNOWLEDGE Re-RFA is a simple, safe, and effective method to control tract bleeding.

Abstract
BACKGROUND Postoperative major complications are potentially fatal to recurrent hepatocellular carcinoma (RHCC) patients. We aimed to construct a prediction model of major complications after RFA for RHCC patients. METHODS We retrospectively reviewed the medical records of 407 RHCC patients who underwent RFA as second treatment. Patients were divided into two groups according to the date of RFA: training cohort (277 patients treated in 2010-2016) and validation cohort (130 patients treated in 2017-2019). 23 clinicopathological variables were recorded and analyzed. The logistic regression model was used to build a prediction model. RESULT Major complications developed in 3.6 % of RHCC patients after RFA. In the multivariate analysis, tumor adjacent vessels (p = 0.004) and hepatitis C (p = 0.022) were associated with postoperative complications. The prediction model was described as follow: Risk score (major complication) = 5.180 + 3.391*tumor location+3.389*hepatic etiology, the Youden index was 0.642, the best cut-off value of the model was 8.57 (sensitivity, 78.57 %, specificity, 84.03 %). The area under the receiver operating characteristic curve of the predictive model was 0.85 (95 % CI, 0.82 to 0.88). The validation of the model demonstrated acceptable results, the sensitivity was 80.00 %, specificity was 98.40 %. CONCLUSIONS This study developed a simple and reliable prediction model of postoperative major complications after RFA for RHCC patients.
