Prediction of Microvascular Invasion in Solitary AFP-Negative Hepatocellular Carcinoma ≤ 5 cm Using a Combination of Imaging Features and Quantitative Dual-Layer Spectral-Detector CT Parameters. Acad Radiol 2023; 30 Suppl 1:S104-S116. [PMID: 36958989 DOI: 10.1016/j.acra.2023.02.015] [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: 12/31/2022] [Revised: 02/13/2023] [Accepted: 02/16/2023] [Indexed: 03/25/2023]
Abstract
RATIONALE AND OBJECTIVES AFP-negative hepatocellular carcinoma (AFPN-HCC) within 5 cm is a special subgroup of HCC. This study aimed to investigate the value of dual-layer spectral-detector CT (DLCT) and construct a scoring model based on imaging features as well as DLCT for predicting microvascular invasion (MVI) in AFPN-HCC within 5 cm. METHODS This retrospective study enrolled 104 HCC patients who underwent multiphase contrast-enhanced DLCT studies preoperatively. Combined radiological features (CR) and combined DLCT quantitative parameter (CDLCT) were constructed to predict MVI. Multivariable logistic regression was applied to identify potential predictors of MVI. Based on the coefficient of the regression model, a scoring model was developed. The predictive efficacy was assessed through ROC analysis. RESULTS Microvascular invasion (MVI) was found in 28 (26.9%) AFPN-HCC patients. Among single parameters, the effective atomic number in arterial phase demonstrated the best predictive efficiency for MVI with an area under the curve (AUC) of 0.792. CR and CDLCT showed predictive performance with AUCs of 0.848 and 0.849, respectively. A risk score (RS) was calculated using the independent predictors of MVI as follows: RS = 2 × (mosaic architecture) + 2 × (corona enhancement) + 2 × (incomplete tumor capsule) + 2 × (2-trait predictor of venous invasion [TTPVI]) + 3 × (CDLCT > -1.229). Delong's test demonstrated this scoring system could significantly improve the AUC to 0.929 compared with CR (p = 0.016) and CDLCT (p = 0.034). CONCLUSION The scoring model combining radiological features with DLCT provides a promising tool for predicting MVI in solitary AFPN-HCC within 5 cm preoperatively.

Li Z, Xu K, Zhou X, Jiao D, Han X. TACE sequential MWA guided by cone-beam computed tomography in the treatment of small hepatocellular carcinoma under the hepatic dome. BMC Cancer 2023; 23:600. [PMID: 37386361 DOI: 10.1186/s12885-023-11066-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 06/14/2023] [Indexed: 07/01/2023] Open
Abstract
PURPOSE An assessment is being conducted to determine the safety and effectiveness of using Cone-beam computed tomography (CBCT)-guided transcatheter arterial chemoembolization (TACE) and microwave ablation (MWA) sequentially to treat small hepatocellular carcinomas (HCCs) located in the hepatic dome. MATERIALS AND METHODS Fifty-three patients with small HCCs in the hepatic dome who underwent TACE combined with simultaneous CBCT-guided MWA were studied. Inclusion criteria were a single HCCs ≤ 5.0 cm or a maximum of three. The safety and interventional-related complications were monitored, and local tumor progression (LTP), overall survival (OS), and prognostic factors for LTP/OS were evaluated. RESULTS The procedures were successfully accomplished in all patients. According to Common Terminology Criteria for Adverse Events (CTCAE), adverse reactions and complications are mainly Grade 1 or 2 (mild symptoms, no or local/noninvasive intervention indicated). Liver and kidney function and alpha-fetoprotein (AFP) levels remained within a reasonable range after 4 weeks of treatment (both p < 0.001). The mean LTP was 44.406 months (95% CI: 39.429, 49.383) and the mean OS rate was 55.157 months (95% CI: 52.559, 57.754). The combination treatment achieved 1-, 3-, and 5-year LTP rates of 92.5%, 69.6%, and 34.5%, respectively; and 1-, 3-, and 5-year OS rates of 100.0%, 88.4%, and 70.2%, respectively. Results from both univariate and multivariate Cox regression analyses showed that the tumor diameter (< 3 cm) and the distance to the hepatic dome (≥ 5 mm, < 10 mm) had a significant impact on the patient's LTP and OS, and were related to better survival. CONCLUSION CBCT-guided TACE combined with simultaneous MWA was a safe and successful treatment of HCCs located under the hepatic dome.

Validation of Software for Patient-Specific Real-Time Simulation of Hepatic Radiofrequency Ablation. Acad Radiol 2022; 29:e219-e227. [PMID: 35039220 PMCID: PMC9276838 DOI: 10.1016/j.acra.2021.12.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 12/04/2021] [Accepted: 12/15/2021] [Indexed: 02/06/2023]
Abstract
RATIONALE AND OBJECTIVES CT-guided radiofrequency ablation (RFA) is a potentially curative minimally invasive treatment for liver cancer. Local tumor recurrence limits the success of RFA for large or irregular tumors as it is difficult to visualize the tissue destroyed. This study was designed to validate a real-time software-simulated ablation volume for intraprocedural guidance. MATERIALS AND METHODS Software that simulated RFA physics calculated ablation volumes in 17 agar-albumin phantoms (7 with a simulated vessel) and in six in-vivo (porcine) ablations. The software-modeled volumes were compared with the actual ablations (physical lesion in agar, contrast CT in the porcine model) and to the volume predicted by the manufacturer's charts. Error was defined as the distance from evenly distributed points on the segmented true ablation volume surfaces to the closest points on the corresponding computer-generated model, and for the porcine model, to the manufacturer-specified ablation volume. RESULTS The average maximum error of the simulation was 2.8 mm (range to 4.9 mm) in the phantoms. The heat-sink effect from the simulated vessel was well-modeled by the simulation. In the porcine model, the average maximum error of the simulation was 5.2 mm (range to 8.1 mm) vs 7.8 mm (range to 10.0mm) for the manufacturer's model (p = 0.009). CONCLUSION A real-time computer-generated RFA model incorporated tine position, energy deposited, and large vessel proximity to predict the ablation volume in agar phantoms with less than 3mm maximum error. Although the in-vivo model had slightly higher maximum error, the software better predicted the achieved ablation volume compared to the manufacturer's ablation maps.

Recurrence Outcome in Hepatocellular Carcinoma within Milan Criteria Undergoing Microwave Ablation with or without Transarterial Chemoembolization. Medicina (B Aires) 2022; 58:medicina58081016. [PMID: 36013483 PMCID: PMC9412845 DOI: 10.3390/medicina58081016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 07/20/2022] [Accepted: 07/25/2022] [Indexed: 11/24/2022] Open
Abstract
Background and Objectives: The recurrence outcome in patients who underwent microwave ablation (MWA) with or without transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) within Milan criteria remains unclear. The aim of this retrospective study was to identify the predictive factors of recurrence in these patients. Materials and Methods: From May 2018 to April 2021, 66 patients with HCC within Milan criteria were enrolled. Local tumor progression (LTP) and recurrence-free survival (RFS) were evaluated. Univariate and multivariate analyses were used to evaluate the risk factors of recurrence. The propensity score analysis was conducted to reduce potential confounding bias. Results: During the median follow-up of 25.07 months (95% confidence interval [CI], 21.85, 28.28), the median time to LTP and RFS were 20.10 (95%CI, 14.67, 25.53) and 13.03 (95%CI, 6.36, 19.70) months. No group difference (MWA vs. MWA + TACE) was found in 1-year cumulative LTP (p = 0.575) and RFS (p = 0.515), but meaningful significant differences were found in two-year recurrence (LTP, p = 0.007 and RFS, p = 0.037). Univariate and multivariate analyses revealed that treatment received before ablation was an independent risk factor of LTP (hazard ratio [HR] 4.37, 95%CI, 1.44, 13.32) and RFS (HR 3.41, 95%CI, 1.49, 7.81). Conclusions: The LTP and RFS in the MWA group were similar to that in the MWA combined with TACE. For HCC within Milan criteria, both groups preferentially selected MWA. More endeavor and rigorous surveillance should be taken to relapse prevention, in patients who have received previous treatment.

Efficacy and Safety of the Arsenic Trioxide/Lipiodol Emulsion in the Transcatheter Arterial Chemoembolization Combined with Apatinib in the Treatment of Advanced Hepatocellular Carcinoma. Can J Gastroenterol Hepatol 2021; 2021:5565793. [PMID: 34458205 PMCID: PMC8397569 DOI: 10.1155/2021/5565793] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 07/12/2021] [Accepted: 08/07/2021] [Indexed: 12/11/2022] Open
Abstract
PURPOSE The goal of this study was to assess the clinical efficacy and safety of the arsenic trioxide (ATO)/lipiodol emulsion in the transcatheter arterial chemoembolization (TACE) combined with apatinib in the treatment of advanced hepatocellular carcinoma (HCC). METHODS From December 2015 to February 2017, a total of 87 patients were consecutively enrolled and underwent ATO-TACE (aTACE) combined with apatinib in the treatment of advanced HCC. The treatment response and adverse events were assessed at the first month and third month after aTACE therapy. Progression-free survival (PFS), overall survival (OS), and treatment-related adverse events were also analyzed. RESULTS 87 patients (57 men; 30 women) were enrolled in the present study. Compared to that at the pre-aTACE examination, the levels of AST and ALT were elevated at the first week after procedure (65.84 U/L ± 22.93 U/L vs. 54.15 U/L ± 19.60 U/L, p=0.032; 63.44 U/L ± 22.50 U/L vs. 51.60 U/L ± 13.89 U/L, p=0.027, respectively). Most of the adverse events were grade 1 or 2 according to National Cancer Institute Common Terminology Criteria for Adverse Event (CTCAE). Of the exception, 4 persons (2%) did have grade 3 hand-foot skin reactions, 1 (1%) had grade 3 diarrhea, 1 (1%) had grade 3 hypertension, and 3 (3%) had grade 3 proteinuria and forced to reduce the dose of apatinib by half. The survival analysis of the combination with aTACE and apatinib therapy found that the median PFS was 10.2 months (95% CI: 8.543-11.857), and the median OS was 23.300 months (95% CI: 20.833-25.767). Additionally, both univariate and multivariate Cox regression revealed that the tumor burden (≤50%) and the patients without portal vein tumor thrombus (PVTT) significantly impacted the patient's PFS and OS and were related to better survival. CONCLUSION aTACE combined with apatinib is a safe and promising treatment approach for patients with advanced HCC. Additionally, tumor burden (≤50%) and the patients without PVTT are associated with better PFS and OS.

Drug-eluting bead trans-arterial chemoembolization combined with microwave ablation therapy vs. microwave ablation alone for early stage hepatocellular carcinoma: a preliminary investigation of clinical value. J Cancer Res Clin Oncol 2021; 148:1781-1788. [PMID: 34405295 PMCID: PMC9189084 DOI: 10.1007/s00432-021-03760-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Accepted: 08/11/2021] [Indexed: 01/29/2023]
Abstract
Purpose To assess the clinical value of drug-eluting bead trans-arterial chemoembolization (DEB-TACE) combined with microwave ablation (MWA) vs. MWA treatment alone for early stage hepatocellular carcinoma (HCC). Materials and methods Consecutive data from 102 HCC patients at early stage who were referred to our hospital from December 2014 to May 2016 were retrospectively collected. Forty-seven patients underwent DEB-TACE combined with MWA treatment, whereas 55 patients underwent MWA alone. After 1 month of treatment, the tumour responses of the patients were assessed using the mRECIST criteria. Treatment-related complications and hepatic function were also analysed for the two groups. In addition, overall survival (OS) and progression-free survival (PFS) were calculated and compared. Results Patients in the combined treatment group (DEB-TACE combined with MWA) presented a better objective response rate (ORR) and disease control rate (DCR) compared with those in the monotherapy group (MWA treatment). The median OS and PFS were longer in the combined treatment group compared with the monotherapy group. Multivariate Cox’s regression further illustrated that DEB-TACE + MWA vs. MWA was an independent protective factor for PFS and OS. No serious treatment-related complications were observed in any of the patients. Conclusion Combined treatment with DEB-TACE appeared to have advantages in prolonging OS and PFS compared to MWA. Therefore, combined treatment was efficient and should be strongly recommended to early stage HCC patients.

MR-guided microwave ablation of hepatocellular carcinoma (HCC): is general anesthesia more effective than local anesthesia? BMC Cancer 2021; 21:562. [PMID: 34001036 PMCID: PMC8130145 DOI: 10.1186/s12885-021-08298-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 05/05/2021] [Indexed: 02/05/2023] Open
Abstract
Background Percutaneous magnetic resonance-guided (MR-guided) MWA procedures have traditionally been performed under local anesthesia (LA) and sedation. However, pain control is often difficult to manage, especially in some cases when the tumor is large or in a specific location, such as near the abdominal wall or close to the hepatic dome. This study retrospectively compared the results of general anesthesia (GA) and local anesthesia (LA) for MR-guided microwave ablation (MWA) in patients with hepatocellular carcinoma (HCC ≤ 5.0 cm) to investigate whether different anesthesia methods lead to different clinical outcomes. Methods The results of the analysis include procedure-related complications, imaging response, and the time to complete two sets of procedures. According to the type of anesthesia, the Kaplan-Meier method was used to compare the local tumor progression (LTP) of the two groups who underwent MR-guided MWA. Results All patients achieved technical success. The mean ablation duration of each patient in the GA group and LA group was remarkably different (P = 0.012). Both groups had no difference in complications or LTP (both P > 0.05). Notably, the tumor location (challenging locations) and the number of lesions (2–3 lesions) could be the main factors affecting LTP (p = 0.000, p = 0.015). Univariate Cox proportional hazard regression indicated that using different anesthesia methods (GA and LA) was not associated with longer LTP (P = 0.237), while tumor location (challenging locations) and the number of lesions (2–3 lesions) were both related to shorter LTP (P = 0.000, P = 0.020, respectively). Additionally, multivariate Cox regression further revealed that the tumor location (regular locations) and the number of lesions (single) could independently predict better LTP (P = 0.000, P = 0.005, respectively). Conclusions No correlation was observed between GA and LA for LTP after MR-guided MWA. However, tumors in challenging locations and the number of lesions (2–3 lesions) appear to be the main factors affecting LTP.

Abstract
Objective Percutaneous tumor ablation is usually performed using computed tomography (CT) or ultrasound (US) guidance, although reliable visualization of the target tumor could be challenging. Magnetic resonance- (MR-) guided ablation provides more reliable visualization of the target tumors and allows multiplanar imaging of the treatment process, making it the modality of choice, in particular if lesions are small. Methods From March 2016 to January 2018, 32 patients scheduled for percutaneous treatment of T1 RCC underwent MR-guided MWA. Complications were classified according to the Clavien grade. Kaplan–Meier survival estimates were calculated to evaluate progression-free survival (PFS). Results Technical success was achieved in all lesions. The mean energy and procedure duration were 61.6 ± 8.7 kJ and 118.2 ± 26.7 min, respectively. The glomerular filtration rate (GFR) dropped rapidly after 1 month of treatment and slowly recovered within three months (P < 0.05). Postoperative pain and fever were the most common adverse events after treatment. Perirenal hematoma, thermal injury of the psoas muscle, and abdominal distension were common complications after MWA, and the incidence rates were 9.4% (3/32), 6.3% (2/32), and 6.3% (2/32), respectively. According to the Clavien grade classification, serious complications include hydrothorax, bowel injury, and renal failure, all of which have a probability of 3.1%. Of note, the three serious complications occurred in one patient. The 1-, 2-, and 3-year PFS rates were 96.9%, 93.8%, and 83.9%, respectively. The mean PFS rates were 33.972 months (95% CI: 33.045, 35.900). Conclusion Microwave ablation is feasible under MR guidance and provides effective treatment of RCC in one session.
