Predicting Long-Term Hepatocellular Carcinoma Response to Transarterial Radioembolization Using Contrast-Enhanced Ultrasound: Initial Experiences. ULTRASOUND IN MEDICINE & BIOLOGY 2021; 47:2523-2531. [PMID: 34130880 PMCID: PMC8355136 DOI: 10.1016/j.ultrasmedbio.2021.05.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 02/26/2021] [Accepted: 05/06/2021] [Indexed: 05/12/2023]
Abstract
Conventional cross-sectional imaging done shortly after radioembolization of hepatocellular carcinoma (HCC) does not reliably predict long-term response to treatment. This study evaluated whether quantitative contrast-enhanced ultrasound (CEUS) can predict the long-term response of HCC to yttrium-90 (Y-90) treatment. Fifteen patients underwent CEUS at three time points: immediately following treatment and 1 and 2 wk post-treatment. Response 3-6 mo after treatment was categorized on contrast-enhanced magnetic resonance imaging by two experienced radiologists using the Modified Response Evaluation Criteria in Solid Tumors. CEUS data were analyzed by quantifying tumor perfusion and residual fractional vascularity using time-intensity curves. Patients with stable disease on magnetic resonance imaging had significantly greater fractional vascularity 2 wk post-treatment (65.15%) than those with partial or complete response (13.8 ± 9.9%, p = 0.007, and 14.9 ± 15.4%, p = 0.009, respectively). Complete responders had lower tumor vascularity at 2 wk than at post-operative examination (-38.3 ± 15.4%, p = 0.045). Thus, this pilot study suggests CEUS may provide an earlier indication of Y-90 treatment response than cross-sectional imaging.

Abstract
OBJECTIVE The purpose of this study was to evaluate the usefulness of CT for quantitative assessment of the neck structures after RFA in patients with benign thyroid nodules. MATERIALS AND METHODS This single-center, retrospective cohort study included 38 patients with benign thyroid nodules who had received RFA and had available pre- and post-treatment CT images. Changes in the tracheal anteroposterior (AP)/transverse diameter ratio, cross-sectional tracheal area, midline deviation of the trachea, and anterior neck angle after RFA were quantitatively measured using CT. Volume reduction rates (VRRs) for the thyroid gland and nodules were measured using CT and US, respectively, and the intraclass correlation coefficient (ICC) was calculated. The paired Wilcoxon signed-rank test was used to compare pre- and post-treatment CT-based measurements, and univariate linear regression analysis was performed to determine the association of VRR with the mean delivered radiofrequency energy, number of RFA sessions, and initial thyroid volume. RESULTS After RFA, the tracheal AP/transverse diameter ratio and midline deviation were significantly decreased while the tracheal area and anterior neck angle were significantly increased (all, p < 0.001). The thyroid volume reduction was also significant (VRR, 42.1% ± 21.1%, p < 0.001), with moderate consistency between the CT-based thyroid VRR and US-based nodule VRR (ICC = 0.68, 95% confidence interval = 0.38-0.83, p < 0.001). The mean delivered radiofrequency energy (p = 0.565), number of RFA sessions (p = 0.209), and initial thyroid volume (p = 0.363) showed no significant association with VRR. CONCLUSION CT-based quantitative assessments may be useful for evaluating improvements in the neck structures after RFA for benign thyroid nodules.

Abstract
Hepatocellular carcinoma (HCC) is a major cause of cancer-related death worldwide. Understanding of the pathogenesis of HCC has significantly improved in the past few years due to advances in genetics, molecular biology and pathology. Several subtypes have been identified with different backgrounds and outcomes, leading to possible changes in disease management and challenging the role of imaging. Indeed, despite its pivotal role in the diagnostic workup, prognosis, and the decision-making process in patients with HCC, these recent developments are progressively redefining the role of imaging. First and most important, liver imaging is shifting from a purely qualitative to a quantitative paradigm, integrating quantitative imaging and radiomics in a digital era. Second, to improve patient management, imaging has gradually moved beyond tumor-centered assessment to include a broader evaluation of the liver and its function. This review describes and discusses these advances in the imaging for the diagnosis and prognosis of HCC.

Correlating serum alpha-fetoprotein in hepatocellular carcinoma with response to Yttrium-90 transarterial radioembolization with glass microspheres (TheraSphere™). HPB (Oxford) 2020; 22:1330-1338. [PMID: 31917103 DOI: 10.1016/j.hpb.2019.12.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2019] [Revised: 09/30/2019] [Accepted: 12/02/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND Few studies have assessed the relationship between serum alpha-fetoprotein (AFP) and yttrium-90 (Y-90) radioembolization response in hepatocellular carcinoma (HCC). The objective of the study was to evaluate whether peri-procedural serum AFP was correlated with Y-90 therapy response in HCC. METHODS Patients undergoing Y-90 radioembolization with glass microspheres (TheraSphere™) for HCC between 2006 and 2013 at a single center were evaluated. The relationship between AFP and 6-month radiographic improvement (complete or partial response by modified RECIST criteria), overall (OS), and disease-specific survival (DSS) were analyzed. RESULTS Seventy-four patients underwent a total of 124 Y-90 infusions. Median age was 65 years, median AFP was 37 ng/mL (range: 2-112,593 ng/mL) and median model for end-stage liver disease score was 6.2 (range:1.8-11.2). Increased AFP was not associated with radiographic improvement (odds ratio (OR) = 0.99, 95% confidence interval (CI) = 0.75-1.30, p = 0.92). Median OS was 15.2 months and was increased in patients with low AFP compared to high AFP (30.8 months vs. 7.8 months, p < 0.001). On multivariable regression analysis, increased AFP was associated with worse OS (OR = 1.11, 95%CI = 1.01-1.22, p = 0.034) and DSS (OR = 1.13, 95%CI = 1.03-1.25, p = 0.018). CONCLUSION Pre-infusion AFP independently predicted survival after Y-90 treatment for HCC, but not radiographic response, and can help guide treatment decisions.

Abstract
OBJECTIVE. Treatment options for hepatocellular carcinoma (HCC) continue to expand. However, given the complexity of the patients including factors such as codominant cirrhosis or portal hypertension and transplant status, it can be difficult to know which treatment is most advantageous. The choice of HCC treatment is perhaps most complex in the setting of HCCs that are 3-5 cm. This article reviews the evidence for locoregional therapies in treating 3- to 5-cm HCCs. CONCLUSION. Combination therapy with transarterial chemoembolization (TACE) and ablation has the most robust and highest level of evidence to support its efficacy and therefore should be considered first-line therapy for nonresectable HCCs that measure 3-5 cm. The studies support that TACE followed by ablation is superior to either TACE alone or ablation alone. Data for transarterial radioembolization (TARE) to treat HCCs in this specific size range are very limited. Additional data are needed about the comparative effectiveness of TACE-ablation combination and TARE and how the TACE-ablation combination compares with surgical resection.
