A Systematic Review about Imaging and Histopathological Findings for Detecting and Evaluating Electroporation Based Treatments Response. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18115592. [PMID: 34073865 PMCID: PMC8197272 DOI: 10.3390/ijerph18115592] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 05/16/2021] [Accepted: 05/19/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Imaging methods and the most appropriate criteria to be used for detecting and evaluating response to oncological treatments depend on the pathology and anatomical site to be treated and on the treatment to be performed. This document provides a general overview of the main imaging and histopathological findings of electroporation-based treatments (Electrochemotherapy-ECT and Irreversible electroporation-IRE) compared to thermal approach, such as radiofrequency ablation (RFA), in deep-seated cancers with a particular attention to pancreatic and liver cancer. METHODS Numerous electronic datasets were examined: PubMed, Scopus, Web of Science and Google Scholar. The research covered the years from January 1990 to April 2021. All titles and abstracts were analyzed. The inclusion criteria were the following: studies that report imaging or histopathological findings after ablative thermal and not thermal loco-regional treatments (ECT, IRE, RFA) in deep-seated cancers including pancreatic and liver cancer and articles published in the English language. Exclusion criteria were unavailability of full text and congress abstracts or posters and different topic respect to inclusion criteria. RESULTS 558 potentially relevant references through electronic searches were identified. A total of 38 articles met the inclusion criteria: 20 studies report imaging findings after RFA or ECT or IRE in pancreatic and liver cancer; 17 studies report histopathological findings after RFA or ECT or IRE; 1 study reports both imaging and histopathological findings after RFA or ECT or IRE. CONCLUSIONS Imaging features are related to the type of therapy administrated, to the timing of re-assessment post therapy and to the imaging technique being used to observe the effects. Histological findings after both ECT and IRE show that the treated area becomes necrotic and encapsulated in fibrous tissue, suggesting that the size of the treated lesion cannot be measured as an endpoint to detect response. Moreover, histology frequently reported signs of apoptosis and reduced vital tissue, implying that imaging criteria, which take into account the viability and not the size of the lesion, are more appropriate to evaluate response to treatment.

Histological Correlation for Radiofrequency and Microwave Ablation in the Local Control of Hepatocellular Carcinoma (HCC) before Liver Transplantation: A Comprehensive Review. Cancers (Basel) 2020; 13:cancers13010104. [PMID: 33396289 PMCID: PMC7795634 DOI: 10.3390/cancers13010104] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 12/24/2020] [Accepted: 12/28/2020] [Indexed: 02/06/2023] Open
Abstract
Simple Summary Liver cancer is a growing problem around the world. Drugs for liver cancer have limited effect, there are not enough donors for liver transplants and many patients are not candidates for surgery to remove the tumor. In many of these cases, hyperthermia can destroy the tumor in situ with minimally invasive methods such as radiofrequency or microwave ablation. In this paper we review the literature evaluating success rates for complete ablation as judged by actual examination of treated tumors that were removed when patients received a liver transplant. While notable successes can be achieved with ablation, the published studies indicate both that complete treatment is not as common as thought and that imaging methods such as computed tomography and magnetic resonance scans do not completely identify residual cancer. There is therefore an important opportunity for improvement in the treatment of this disease. Abstract Radiofrequency ablation (RFA) and microwave ablation (MWA) are the most widely studied and applied ablation techniques for treating primary and secondary liver tumors. These techniques are considered curative for small hepatic tumors, with post-ablation outcomes most commonly assessed by an imaging follow up. However, there is increasing evidence of a discrepancy between radiological and pathological findings when ablated lesions are evaluated following liver resection or liver transplantation. A comprehensive review of the available literature reporting the complete pathological response (cPR) following RFA and MWA was performed to estimate the success rate and identify the factors associated with treatment failure. Following RFA, cPR is reported in 26–96% of tumors compared to 57–95% with MWA. Larger tumor size and vessels larger than 3 mm adjacent to the treated tumor are the most important factors identified by previous studies associated with viable residual tumors after RFA. Correlating post-ablation radiological studies with pathological findings shows that computed tomography (CT) and magnetic resonance imaging (MRI) have low sensitivity but high specificity for detecting residual viable or recurrent hepatocellular carcinoma (HCC) tumors. There are promising recent reports combining multiprobe ablation techniques with three-dimensional treatment planning software and stereotactic-aiming instrumentation to achieve more than 90% cPR in both small and large HCC tumors. In conclusion, the reported success for achieving cPR in HCC following RFA and MWA is highly variable in different studies and decreases with increasing lesion size and unfavorable tumor characteristics. Very few studies have reported a high rate of cPR. As these studies are single-center and retrospective, they need to be further validated and reproduced in other clinical settings.

Stereotactic Radiofrequency Ablation of Hepatocellular Carcinoma: a Histopathological Study in Explanted Livers. Hepatology 2019; 70:840-850.

Abstract
This retrospective study was performed to evaluate the efficacy of three-dimensional (3D)-navigated multiprobe radiofrequency ablation (RFA) with intraprocedural image fusion for treatment of hepatocellular carcinoma (HCC) by histopathological examination. From 2009 to 2018, 97 patients (84 men, 13 women; median age, 60 years; range, 1-71) were transplanted after bridging therapy of 195 HCCs by stereotactic RFA (SRFA). The median interval between the first SRFA and transplantation was 6.8 months (range, 0-71). The rate of residual vital tissue (RVT) could be assessed in 188 of 195 lesions in 96 of 97 patients by histological examination of the explanted livers using hematoxylin and eosin (H&E) and Tdt-mediated UTP nick-end labeling (TUNEL) stains. Histopathological results were compared with the findings of the last computed tomography (CT) imaging before liver transplantation (LT). Median number and size of treated tumors were 1 (range, 1-8) and 2.5 cm (range, 1-8). Complete radiological response was achieved in 186 of 188 nodules (98.9%) and 94 of 96 patients (97.9%) and complete pathological response in the explanted liver specimen in 183 of 188 nodules (97.3%) and 91 of 96 patients (94.8%), respectively. In lesions ≥3 cm, complete tumor cell death was achieved in 50 of 52 nodules (96.2%). Residual tumor did not correlate with tumor size (P = 0.5). Conclusion: Multiprobe SRFA with intraprocedural image fusion represents an efficient, minimally invasive therapy for HCC, even with tumor sizes larger than 3 cm, and without the need of a combination with additional treatments. The results seem to justify the additional efforts related to the stereotactic approach.

Abstract
Irreversible electroporation (IRE) is a novel therapy that has shown to be a feasible and promising alternative to conventional ablative techniques when treating tumors near vital structures or blood vessels. The clinical efficacy of IRE has been evaluated using established imaging criteria. This study evaluates the histologic and imaging response of hepatic and pancreatic malignancies that were surgically resected after IRE. In total, 12 lesions ablated with IRE were included, including 3 pancreatic carcinomas, 5 primary tumors of the liver, and 4 metastatic tumors of the liver. The rate of complete response to IRE was 25% based on the histologic evaluation of the resected tumors. Although treatment-related vessel wall changes were noted in several cases in histologic findings, there was no evidence of vascular luminal narrowing or obliteration in any of the specimens. The imaging response to IRE before surgical resection usually resulted in underestimation of disease burden when compared with the histologic response seen on the resected specimens.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide and has a poor prognosis if untreated. It is ranked the third among the causes of cancer-related death. There are multiple etiologic factors that can lead to HCC. Screening for early HCC is challenging due to the lack of well specific biomarkers. However, early diagnosis through successful screening is very important to provide cure rate. Liver transplantation (LT) did not gain wide acceptance until the mid-1980s, after the effective immunosuppression with cyclosporine became available. Orthotopic LT is the best therapeutic option for early, unresectable HCC. It is limited by both, graft shortage and the need for appropriate patient selection. It provides both, the removal of tumor and the remaining cirrhotic liver. In Milan, a prospective cohort study defined restrictive selection criteria known as Milan criteria (MC) that led to superior survival for transplant patients in comparison with any other previous experience with transplantation or other options for HCC. When transplantation occurs within the established MC, the outcomes are similar to those for nonmalignant liver disease after transplantation. The shortage of organs from deceased donors has led to the problems of long waiting times and dropouts. This has led to the adoption of extended criteria by many centers. Several measures have been taken to solve these problems including prioritization of patients with HCC, use of pretransplant adjuvant treatment, and living donor LT.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is among the most frequent malignant diseases worldwide. In the vast majority of cases, it is associated with liver cirrhosis. Liver transplantation (OLT) is potentially the gold standard treatment for patients suffering HCC in cirrhosis, because of synchronous eradication of HCC and of the underlying hepatic disease. The aim of this study was to evaluate long-term outcomes of OLT in HCC patients. MATERIAL AND METHODS Between January 2000 and December 2011, 43 patients who were diagnosed with HCC in liver cirrhosis and underwent OLT in our department, were identified from a prospective database. All patients received their grafts from deceased donors. We analyzed demographic data, laboratory values, number and size of lesions, primary liver disease, diagnostic methods, bridging therapy modalities, and postoperative outcomes, including complications, recurrences, and their treatment. RESULTS Patient follow-up as of January 2012 or to death ranged from 0 to 138 months (median, 59; mean, 63). None of the patients were lost to follow-up. The gender bias was 85%:15% (male:female) and the median age, 57.8 years (range, 44-69). The most common underlying diseases for cirrhosis and HCC were alcoholic (n = 12) and hepatitis C (n = 16). Thirty-one subjects underwent bridging therapy through transarterial chemoembolization (TACE), and/or radiofrequency ablation. All patients underwent OLT within the Milan criteria according to the preoperative evaluation and histopathologic examination of the explanted liver. Twenty-one of them suffered postoperative complications (48.8%). HCC recurrence, which occurred in 5 (10.4%), was treated by surgery (n = 3), systemic chemotherapy with sorafenib (n = 1), or TACE (n = 1). CONCLUSIONS OLT for HCC in cirrhosis, displays a relatively high complication rate. It shows good survivals with and low recurrence.

Abstract
CONTEXT No study has evaluated radiology/pathology correlation of percentage viable tumor (PVT) estimates in ablated hepatocellular carcinoma (HCC) to examine the reliability of radiologic estimates. OBJECTIVE To determine how well interdisciplinary PVT estimates correlate and identify pathologic factors that influence this correlation. DESIGN Pathologists and radiologists established blinded PVT estimates in 22 HCC ablation cavities. Paired sample t tests examined the differences between the interdisciplinary estimates. RESULTS Fifteen cavities had pathologic viable tumor (VT) (68%) and 6 had radiographic VT (22%). Radiology's sensitivity for detecting VT was 40% and the specificity was 100%. Pathology detected significantly more VT than radiology (pathology mean = 22.3% versus radiology mean = 2.6%; P = .005). Five cavities had tumor growth in a discontinuous rim pattern, 7 in a nodular pattern, and 3 in a solid pattern. Radiology did not detect VT in cavities with a discontinuous rim pattern (sensitivity = 0%) but did detect VT in 3 cavities with a nodular pattern (sensitivity = 43%), and in all cavities with a solid pattern (sensitivity = 100%). There was no significant difference in PVT estimates in cavities 3.5 cm or larger (P = .07), but there was a significant difference in cavities smaller than 3.5 cm (P = .01). CONCLUSION This study clarifies that the risk of underestimation by imaging is greatest in small lesions (<3.5 cm), though the sensitivity of detection depends primarily on the tumor growth pattern within the cavity. This underestimation raises the question of whether basing treatment decisions on a radiologic impression of complete ablation is valid.

Abstract
Purpose Radiofrequency ablation (RFA) is an accepted treatment option for primary and metastatic liver tumors. As percutaneous RFA has some limitations, laparoscopic RFA (LRFA) has been used as a therapeutic alternative for the treatment of hepatic malignancies. Methods Between March 2006 and September 2009, thirty patients with hepatic malignancies that were contraindicated for resection or percutaneous RFA underwent LRFA. Indications for this procedure were hepatocellular carcinoma (HCC, 21 patients), metastatic liver tumor (8 patients) and intrahepatic cholangiocarcinoma (1 patient). Results Among the 30 patients who underwent LRFA, 5 patients underwent concomitant laparoscopic liver resection. Intraoperative laparoscopic ultrasound detected new malignant lesions in 4 patients (13.3%). A total of 46 lesions were ablated by LRFA. There was no postoperative mortality. The three-year overall survival rate was 83.7% for the HCC group and 64.3% for the metastatic group. Conclusion LRFA for hepatic malignancies proved to be a safe and effective treatment. Also, this procedure is indicated for lesions that are not amenable to percutaneous RFA or liver resection.

Abstract
Hepatocellular carcinoma (HCC) represents one of the most common cancers worldwide with rising incidence in developed countries. The best treatment options with curative intent for patients with HCC are liver resection or transplantation, although the role of hepatic ablative therapies has also been recognized. Surgical resection has emerged as the primary treatment in carefully selected patients of HCC. With the advances in surgical and radiological techniques, the perioperative mortality has been reduced to less than 5 % depending on the extent of resection and hepatic reserve. The role of liver transplantation (LT) as the mainstay of treatment for the majority of patients with HCC has evolved in the last few decades. Historically, the Milan criteria have been considered the gold standard for selecting patients; more expanded selection criteria to include those with more advanced tumors have been implemented in recent years. Living donor liver transplantation (LDLT) has emerged as a way to expand the donor pool and has influenced the role of transplantation for HCC, especially in communities with little access to cadaveric transplantation. Salvage transplantation is an alternative option as it allows a window for the biologically less favorable lesions to declare tumor behavior. Salvage transplantation also decreases the burden on transplant resources. Sirolimus, a novel immunosuppressant drug with anti-tumor effect, may have a role in limiting the severity of recurrent disease after transplantation for HCC, and play an important role in the future management of transplant recipients. This article examines the literature on current status of management of HCC.

Abstract
Although liver transplantation is a widely accepted treatment for hepatocellular carcinoma (HCC), much controversy remains and there is no generally accepted set of guidelines. An international consensus conference was held on Dec 2-4, 2010, in Zurich, Switzerland, with the aim of reviewing current practice regarding liver transplantation in patients with HCC and to develop internationally accepted statements and guidelines. The format of the conference was based on the Danish model. 19 working groups of experts prepared evidence-based reviews according to the Oxford classification, and drafted recommendations answering 19 specific questions. An independent jury of nine members was appointed to review these submissions and make final recommendations, after debates with the experts and audience at the conference. This report presents the final 37 statements and recommendations, covering assessment of candidates for liver transplantation, criteria for listing in cirrhotic and non-cirrhotic patients, role of tumour downstaging, management of patients on the waiting list, role of living donation, and post-transplant management.

Although liver transplantation is a widely accepted treatment for hepatocellular carcinoma (HCC), much controversy remains and there is no generally accepted set of guidelines. An international consensus conference was held on Dec 2-4, 2010, in Zurich, Switzerland, with the aim of reviewing current practice regarding liver transplantation in patients with HCC and to develop internationally accepted statements and guidelines. The format of the conference was based on the Danish model. 19 working groups of experts prepared evidence-based reviews according to the Oxford classification, and drafted recommendations answering 19 specific questions. An independent jury of nine members was appointed to review these submissions and make final recommendations, after debates with the experts and audience at the conference. This report presents the final 37 statements and recommendations, covering assessment of candidates for liver transplantation, criteria for listing in cirrhotic and non-cirrhotic patients, role of tumour downstaging, management of patients on the waiting list, role of living donation, and post-transplant management.

Abstract
Hepatocellular carcinoma (HCC) is the commonest primary malignancy of the liver. It usually occurs in the setting of chronic liver disease and has a poor prognosis if untreated. Orthotopic liver transplantation (OLT) is a suitable therapeutic option for early, unresectable HCC particularly in the setting of chronic liver disease. Following on from disappointing initial results, the seminal study by Mazzaferro et al in 1996 established OLT as a viable treatment for HCC. In this study, the “Milan criteria” were applied achieving a 4-year survival rate similar to OLT for benign disease. Since then various groups have attempted to expand these criteria whilst maintaining long term survival rates. The technique of living donor liver transplantation has evolved over the past decade, particularly in Asia, and published outcome data is comparable to that of OLT. This article will review the evidence, indications, and the future direction of liver transplantation for liver cancer.

Abstract
Imaging studies play a crucial role in the diagnosis and staging of hepatocellular carcinoma (HCC). Yet, assessment of tumor response is another important goal for imaging. The imaging techniques most commonly used for assessing tumor response include computed tomography and magnetic resonance imaging. Imaging modalities and imaging criteria vary according to the treatment (surgical resection and transplantation or nonsurgical treatments such as transarterial chemoembolization, radiofrequency ablation, and molecular targeted therapy). Efficacy of nonsurgical treatments for malignancy is usually evaluated with RECIST criteria. These criteria, based on tumor shrinkage, are often inappropriate in HCCs. The response criteria should take into account tumor necrosis induced by treatment. Today, tumor necrosis is estimated by a disappearance of hypervascularization on contrast-enhanced imaging. New tools such as functional imaging (perfusion imaging, diffusion-weighted MR imaging) could be of major importance. In this article, we present a summary of the most recent information on the role of imaging in assessing treatment efficacy in HCCs.

Abstract
Since it was first performed in 1963, liver transplantation has become the only effective curative treatment in patients with liver failure. During the interval between being added to the waiting list and receiving a graft, the patient's condition may deteriorate as a result of disease progression or complications of the underlying liver disease. Both may result in death, removal from the waiting list because of futility of the procedure or, a worsened outcome following transplantation. The main aims during this period are to delay or prevent further deterioration in the patient's condition, to optimize their general medical health, to prevent, detect and treat any complications, and to offer treatment for specific conditions to improve the patient's overall outcome following liver transplantation.

Abstract
Hepatocellular carcinoma is one of the most frequently encountered malignancies worldwide. Its association with cirrhosis increases the difficulty of diagnosis and therapy. Different approaches, ranging from medical treatment to highly complex ablative and surgical therapies, including liver resection and transplantation have significantly improved the outcome of this disease. This article reviews the current diagnostic challenges and the available surveillance and classification protocols. Available therapeutic approaches, indications, contraindications and outcome of liver resection, liver transplantation, living donor liver transplantation, are outlined in detail. Ablative procedures and their role and efficiency as "bridging" methods to liver transplantation are included in the review.

Abstract
BACKGROUND The real efficacy of radiofrequency ablation (RFA) in destroying hepatocellular carcinoma is not completely known, nor is the ability of computed tomography (CT) to precisely assess response. Our aims were to analyze pathological response, tumor size influence, and CT response evaluation. MATERIALS AND METHODS This was a retrospective study of 30 hepatocellular carcinoma nodules treated by RFA before liver transplant (LT) in 28 patients. Pathological study of the whole removed liver was then performed and the tumor response was classified as complete, incomplete, or absent. The biggest nodule diameter was estimated by CT or ultrasound. The procedure was carried out percutaneously in all but 3 patients, and in those 3 it was done surgically. RESULTS The pathological response was complete in 14 nodules (46.7%) and incomplete in 16 (53.3%). The differences in mean preoperative diameter between cases with complete and incomplete response were not significant (p = 0.3). We found that small tumors were not always completely destroyed, whereas bigger tumors could be successfully deleted. There was no clear association between any location and better or poorer response. The detection of RFA incomplete response by means of CT scan had 50% sensitivity and 100% specificity. CONCLUSIONS In our experience, RFA can achieve some degree of tumor destruction in every treated case of hepatocellular carcinoma, the complete response rate being slightly lower than half. We have not found any association of response with tumor size or interval RFA-transplant. Second, CT had not enough sensitivity to assess RFA response of hepatocellular carcinoma.

Abstract
As a minimally invasive therapy, radiofrequency ablation (RFA) is used to cure the unresectable liver cancer. Many investigations demonstrated that RFA can not only result in coagulation necrosis of tumors, but also promote apoptosis of cancer cells, inhibit angiogenesis of carcinoma, improve tumor immunogenicity and elevate antitumor activity of the body. This review discusses the mechanism of RFA in treating liver cancer.

Abstract
BACKGROUND Neoplastic seeding of hepatocellular carcinoma may arise after radiofrequency ablation. AIMS In order to clarify the real risk of seeding, we observed a prospective cohort of patients undergoing radiofrequency ablation. METHODS Ninety-three (22.9%) out of 406 consecutive patients with hepatocellular carcinoma superimposed to cirrhosis diagnosed at our Liver Unit (2000-2005) were selected for radiofrequency ablation according to the Barcelona 2000 EASL guidelines. Seventy-one patients were treated by a percutaneous approach and 22 at laparotomy. After radiofrequency ablation ultrasound scan was repeated every 3 months and spiral-computed tomography every 6 months. RESULTS Overall 145 sessions were performed in 93 patients: 113 (77.9%) by a percutaneous approach and 32 (22.1%) at laparotomy. The median follow-up was 23 months (range 1-60). Only 1 of the 71 patients (1.4%; 95% C.I. 0.25-7.56) treated percutaneously and none of the 22 (0%; 95% C.I. 0-14.8) treated at laparotomy showed neoplastic seeding. CONCLUSION In our experience the risk of seeding of hepatocellular carcinoma after radiofrequency ablation was small (1.1% per patient, 95% C.I. 0.19-5.84; 0.7% per procedure, 95% C.I. 0.12-3.80). A stringent selection of patients for radiofrequency ablation and retraction of the needle with a hot tip may have been instrumental in obtaining this low frequency.

Abstract
BACKGROUND The model for end-stage liver disease (MELD) is used in prioritizing cirrhotic patients awaiting liver transplantation. Patients with small hepatocellular carcinoma (HCC) are eligible candidates. An HCC-MELD equation was recently proposed to predict the dropout rate of HCC patients on the waiting list. This study aimed to validate the accuracy of this equation. METHODS We investigated 390 patients with small HCC who were candidates for liver transplantation and underwent locoregional therapy. RESULTS The estimated probability of dropout according to the equation was 8.2% for T1 stage and 13.5% for T2 stage HCC (p < 0.0001). The actual disease progression rate at three months was 2.1% for T1 and 3.0% for T2 stage HCC. At six months, the progression rate was 5.3% for T1 stage and 6.8% for T2 stage. The area under receiver operating characteristic curve of the HCC-MELD equation was 0.81 at three months and 0.80 at six months. Patients undergoing radiofrequency ablation (RFA) had significantly lower dropout rates compared with other treatment groups according to the equation (p = 0.0007). The actual tumor progression rate was also the lowest for the RFA group at both three and six months. CONCLUSION The HCC-MELD equation is a feasible predictive model for patients with small HCC undergoing locoregional therapy.

Abstract
BACKGROUND Radiofrequency ablation (RFA) is an established treatment for hepatocellular carcinoma (HCC) in patients awaiting liver transplantation, due to its comparably low rate of complication and high effectiveness. Complications are thought to be rare and mostly self-limiting. By contrast, we report on a life-threatening complication and discuss it in the context of other complications. PATIENTS AND METHODS Out of a total of 149 RFA procedures, the incidence of major complications was 4% on a per-procedure basis. Mortality was 0.67%. Major complications included intractable pain, intrahepatic hematoma, skinburn at the site of patch electrode, and sectorial bile duct stricture. All complications occurred after percutaneous RFA. Highlighted is a young patient listed for liver transplantation because of HCC recurrence following hepatic resection, who was treated by percutaneous RFA as a bridging therapy until a suitable graft became available. Post-operatively, gastric perforation occurred due to heat injury of the gastric wall. CONCLUSIONS The percutaneous RFA approach can occasionally lead to detrimental complications, particularly in patients with intra-abdominal adhesions, due to previous surgery if new intrahepatic malignant lesions accrue near the resection margin. Even widespread HCC disease can be treated effectively with orthotopic liver transplantation if the tumor growth is limited to the liver.
