Transarterial Chemoembolization (TACE) Combined with Lenvatinib versus TACE Alone in Intermediate-Stage Hepatocellular Carcinoma Patients Beyond Up-To-Seven Criteria: A Retrospective, Propensity Score-Matched Analysis. Acad Radiol 2024:S1076-6332(24)00280-0. [PMID: 38760273 DOI: 10.1016/j.acra.2024.04.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 04/17/2024] [Accepted: 04/26/2024] [Indexed: 05/19/2024]
Abstract
RATIONALE AND OBJECTIVES To compare the treatment efficacy and safety of transarterial chemoembolization (TACE) combined with lenvatinib versus TACE alone in patients with intermediate-stage hepatocellular carcinoma (HCC) beyond up-to-seven criteria. MATERIALS AND METHODS A total of 107 newly diagnosed HCC patients with Barcelona Clinic Liver Cancer stage B HCC beyond up-to-seven criteria were included in this retrospective cohort study. These patients were divided into two groups: TACE-Lenv group and TACE alone group. Propensity score matching was used to account for potential confounding factors. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), downstaging rate, liver function, and adverse events (AEs) were recorded and evaluated. RESULTS Both the median OS and median PFS were significantly longer in the TACE-Lenv group compared to the TACE alone group (median OS: 28.0 vs 12.0 months, P = 0.017; median PFS [mRECIST]: 8.2 vs 3.7 months, P = 0.018; median PFS [RECIST v1.1]: 8.9 vs 3.7 months, P = 0.003). Furthermore, the ORR and DCR were also significantly higher in TACE-Lenv group (ORR: 94% [30/32] vs 47% [15/32], P < 0.001; DCR: 97% [31/32] vs 62% [20/32], P < 0.001). There were no significant differences in terms of liver function and grade 3 or 4 AEs rate between two groups. CONCLUSION The combination of TACE and lenvatinib provides clinical benefits for patients with intermediate HCC beyond the up-to-seven criteria, has an acceptable safety profile, shows a trend towards improving liver function, and does not increase the occurrence of grade 3-4 AEs. KEY POINTS The efficacy of transarterial chemoembolization in intermediate-stage hepatocellular carcinoma patients is partially unsatisfactory. Addition of lenvatinib to transarterial chemoembolization improves OS, PFS, ORR, and DCR for patients with intermediate-stage hepatocellular carcinoma beyond the up-to-seven criteria. This combination therapy is a superior treatment option for intermediate-stage hepatocellular carcinoma patients with high tumor burden.

Multiple asynchronous recurrence as a predictive factor for refractoriness against locoregional and surgical therapy in patients with intermediate-stage hepatocellular carcinoma. Sci Rep 2024; 14:10896. [PMID: 38740983 DOI: 10.1038/s41598-024-61611-4] [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: 08/14/2023] [Accepted: 05/07/2024] [Indexed: 05/16/2024] Open
Abstract
Development of subclassification of intermediate-stage hepatocellular carcinoma (HCC) by treatment suitability is in demand. We aimed to identify predictors that define treatment refractoriness against locoregional(transarterial chemoembolization(TACE) or thermal ablation) and surgical therapy. This multicenter retrospective study enrolled 1167 HCC patients between 2015 and 2021. Of those, 209 patients were initially diagnosed with intermediate-stage HCC. Treatment refractoriness was defined as clinical settings that meets the following untreatable progressive conditions by TACE (1) 25% increase of intrahepatic tumor, (2) transient deterioration to Child-Pugh class C, (3) macrovascular invasion or extrahepatic spread, within one year. We then analyzed factors contributing to treatment refractoriness. The Child-Pugh score/class, number of tumors, infiltrative radiological type, and recurrence were significant factors. Focusing on recurrence as a predictor, median time to untreatable progression (TTUP) was 17.2 months in the recurrence subgroup whereas 35.5 months in the initial occurrence subgroup (HR, 2.06; 95% CI, 1.44-2.96; P = 0.001). Median TTUP decreased in cases with more later times of recurrence (3-5 recurrences, 17.3 months; ≥ 6 recurrences, 7.7 months). Recurrence, even more at later times, leads to increased treatment refractoriness. Early introduction of multidisciplinary treatment should be considered against HCC patients after multiple recurrent episodes.

Construction of a prognostic model for hepatocellular carcinoma patients receiving transarterial chemoembolization treatment based on the Tumor Burden Score. BMC Cancer 2024; 24:306. [PMID: 38448905 PMCID: PMC10916036 DOI: 10.1186/s12885-024-12049-4] [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: 11/12/2023] [Accepted: 02/23/2024] [Indexed: 03/08/2024] Open
Abstract
BACKGROUND Patients with hepatocellular carcinoma (HCC) who undergo transarterial chemoembolization (TACE) may have varied outcomes based on their liver function and tumor burden diversity. This study aims to assess the prognostic significance of the tumor burden score (TBS) in these patients and develop a prognostic model for their overall survival. METHODS The study involved a retrospective analysis of 644 newly diagnosed HCC patients undergoing TACE treatment. The individuals were assigned randomly to a training cohort (n = 452) and a validation cohort (n = 192). We utilized a multivariate Cox proportional risk model to identify independent preoperative predictive factors. We then evaluated model performance using the area under the curve (AUC), consistency index (c-index), calibration curve, and decision curve analysis (DCA) methods. RESULTS The multivariate analysis revealed four prognostic factors associated with overall survival: Tumor Burden Score, Tumor Extent, Types of portal vein invasion (PVI), and Child-Pugh score. The total score was calculated based on these factors. The model demonstrated strong discriminative ability with high AUC values and c-index, providing high net clinical benefits for patients. Based on the model's scoring results, patients were categorized into high, medium, and low-risk groups. These results were validated in the validation cohort. CONCLUSIONS The tumor burden score shows promise as a viable alternative prognostic indicator for assessing tumor burden in cases of HCC. The new prognostic model can place patients in one of three groups, which will estimate their individual outcomes. For high-risk patients, it is suggested to consider alternative treatment options or provide the best supportive care, as they may not benefit significantly from TACE treatment.

Factors associated with increased risk of peritoneal seeding after radiofrequency ablation for hepatocellular carcinoma. Abdom Radiol (NY) 2023; 48:3243-3252. [PMID: 37389604 DOI: 10.1007/s00261-023-03987-x] [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: 11/12/2022] [Revised: 01/28/2023] [Accepted: 01/30/2023] [Indexed: 07/01/2023]
Abstract
PURPOSE To evaluate the incidence, risk factors, and prognosis associated with peritoneal seeding after percutaneous radiofrequency ablation (RFA) for HCC, focusing on viable tumors after previous locoregional treatment, including TACE and RFA. METHODS Exactly 290 patients (mean age, 67.9 years ± 9.74; 223 men) with 383 HCCs (mean size, 15.9 mm ± 5.49) who underwent RFA between June 2012 and December 2019 were included in this retrospective study. Among them, 158 had history of previous treatment (mean number, 1.3 ± 1.8) with 109 viable HCCs. Cumulative seeding after RFA was estimated using the Kaplan-Meier method. Independent factors affecting seeding were investigated using multivariable Cox proportional hazards regression analysis. RESULTS Median follow-up was 1175 days (range: 28-4116). Seeding incidence was 4.1 (12/290) and 4.7% (17/383) per patient and tumor, respectively. The median time interval between RFA and detection of seeding was 785 days (range: 81-1961). Independent risk factors for seeding included subcapsular tumor location (hazard ratio [HR] 4.2; 95% confidence interval [CI] 1.4, 13.0; p = 0.012) and RFA for viable HCC after previous locoregional treatment (HR 4.5; 95% CI 1.7, 12.3; p = 0.003). Subgroup analysis for viable tumors, revealed no significant difference in cumulative seeding rates between the TACE and RFA groups (p = 0.078). Cumulative overall survival rates differed significantly between patients with and without seeding metastases (p < 0.001). CONCLUSION Peritoneal seeding after RFA is a rare, delayed complication. Subcapsular-located and viable HCC after previous locoregional treatment are potential risk factors for seeding. Seeding metastases could affect the prognosis of patients who cannot receive local therapy.

TACE responser NDRG1 acts as a guardian against ferroptosis to drive tumorgenesis and metastasis in HCC. Biol Proced Online 2023; 25:13. [PMID: 37208604 DOI: 10.1186/s12575-023-00199-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 04/13/2023] [Indexed: 05/21/2023] Open
Abstract
BACKGROUND The treatment efficacy of transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) varies widely between individuals. The aim of this study was to identify subtype landscapes and responser related to TACE, and further clarify the regulatory effect and corresponding mechanism of NDRG1 on HCC tumorgenesis and metastasis. METHODS The principal component analysis (PCA) algorithm was used to construct a TACE response scoring (TRscore) system. The random forest algorithm was applied to identify the TACE response-related core gene NDRG1 of HCC, and its role in the prognosis of HCC was explored. The role of NDRG1 in the progression and metastasis of HCC and functional mechanism were confirmed using several experimental methods. RESULTS Based on the GSE14520 and GSE104580 cohorts, we identified 2 TACE response-related molecular subtypes for HCC with significant differences in clinical features, and the TACE prognosis of Cluster A was significantly better than that of Cluster B (p < 0.0001). We then established the TRscore system and found that the low TRscore group showed a higher probability of survival and a lower rate of recurrence than the high TRscore group (p < 0.05) in both the HCC and TACE-treated HCC cohorts within the GSE14520 cohort. NDRG1 was determined to be the the hub gene associated with the TACE response of HCC and its high expression suggested a poor prognosis. Furthermore, The suppression of NDRG1 konckdown in tumorgenesis and metastasis of HCC was clarified in both vivo and vitro, which was importantly achieved through inducing ferroptosis in HCC cells, especially contributing to RLS3-induced ferroptosis. CONCLUSION The constructed TACE response-related molecular subtypes and TRscores can specifically and accurately predict TACE prognosis for HCC. In addition, the TACE response-related hub gene NDRG1 may act as a guardian against ferroptosis to drive tumorgenesis and metastasis in HCC, which laid a new foundation for the development of new potential targeted therapy strategies to improve disease prognosis in HCC patients.

Possible use of Digital Variance Angiography in Liver Transarterial Chemoembolization: A Retrospective Observational Study. Cardiovasc Intervent Radiol 2023; 46:635-642. [PMID: 37076552 PMCID: PMC10156832 DOI: 10.1007/s00270-023-03420-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 03/11/2023] [Indexed: 04/21/2023]
Abstract
PURPOSE Digital variance angiography (DVA), a recently developed image processing technology, provided higher contrast-to-noise ratio (CNR) and better image quality (IQ) during lower limb interventions than digital subtraction angiography (DSA). Our aim was to investigate whether this quality improvement can be observed also during liver transarterial chemoembolization (TACE). MATERIALS AND METHODS We retrospectively compared the CNR and IQ parameters of DSA and DVA images from 25 patients (65% male, mean ± SD age: 67.5 ± 11.2 years) underwent TACE intervention at our institute. CNR was calculated on 50 images. IQ of every image set was evaluated by 5 experts using 4-grade Likert scales. Both single image evaluation and paired image comparison were performed in a blinded and randomized manner. The diagnostic value was evaluated based on the possibility to identify lesions and feeding arteries. RESULTS DVA provided significantly higher CNR (mean CNRDVA/CNRDSA was 1.33). DVA images received significantly higher individual Likert score (mean ± SEM 3.34 ± 0,08 vs. 2.89 ± 0.11, Wilcoxon signed-rank p < 0.001) and proved to be superior also in paired comparisons (median comparison score 1.60 [IQR:2.40], one sample Wilcoxon p < 0.001 compared to equal quality level). DSA could not detect lesion and feeding artery in 28 and 36% of cases, and allowed clear detection only in 22% and 16%, respectively. In contrast, DVA failed only in 8 and 18% and clearly revealed lesions and feeding arteries in 32 and 26%, respectively. CONCLUSION In our study, DVA provided higher quality images and better diagnostic insight than DSA; therefore, DVA could represent a useful tool in liver TACE interventions. LEVEL OF EVIDENCE III Non-consecutive study.

Super-selective transcatheter vesical arterial chemoembolization with drug-loaded beads for muscle-invasive bladder cancer with hematuria. Abdom Radiol (NY) 2023; 48:780-786. [PMID: 36477632 DOI: 10.1007/s00261-022-03748-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 11/09/2022] [Accepted: 11/10/2022] [Indexed: 12/12/2022]
Abstract
PURPOSE This retrospective study aimed to evaluate the clinical safety and efficacy of super-selective transcatheter vesical arterial chemoembolization with epirubicin-loaded CalliSpheres® beads (DEB-TACE) for treating muscle-invasive bladder cancer with hematuria. METHODS We reviewed the retrospective records of 20 muscle-invasive bladder cancer patients with hematuria who were treated with super-selective transcatheter vesical arterial by oxaliplatin and 100-300-μm CalliSpheres loaded with epirubicin. The primary outcomes were the technical and clinical success rates. The secondary outcomes were complications, treatment responses, quality of life (QOL), median overall survival, and 1- and 2-year survival rates. QOL was routinely assessed by nurses at admission and during telephone follow-up 4 weeks after discharge. RESULTS The technical success rate was 80.0% (16/20). Bleeding was controlled after the first embolization in 18/20 patients and after re-embolization within 7 days of the first embolization in the remaining two patients. The clinical success rate was 90% (18/20). After 4 weeks of follow-up, the mean hematocrit and hemoglobin levels improved significantly (P < 0.05). Four patients (20.0%) showed hematuria recurrence during a 4-8-month follow-up period. There were no severe complications, such as necrosis of the bladder, genitals, perineal skin, or procedure-related deaths. The complete response, partial response, stable disease, and progressive disease frequencies were 5.0%, 55.0%, 25.0%, and 15.0%, respectively, resulting in an objective response rate of 60.0% and a disease control rate of 85.0% after 1 month. 4 weeks after embolization, QOL was significantly higher than that pre-operation, except for social/family status (P < 0.05). The median overall survival was 18.5 months, and the 1- and 2-year survival rates were 75.0% and 46.7%, respectively. CONCLUSION DEB-TACE is safe and effective for treating muscle-invasive bladder cancer with hematuria, preserving bladder function and improving the QOL.

Abstract
Transarterial chemoembolization (TACE) has been demonstrated to provide a survival benefit for patients with unresectable hepatocellular carcinoma (HCC). However, conventional TACE still faces limitations associated with complications, side effects, unsatisfactory tumor responses, repeated treatment, and narrow indications. For further improvement of TACE, additional beneficial functions such as degradability, drug-loading and releasing properties, detectability, targetability, and multiple therapeutic modalities were introduced. The purpose here is to provide a comprehensive overview of current and emerging particulate embolization technology with respect to materials. Therefore, this review systematically identified and described typical features, various functions, and practical applications of recently emerging micro/nano materials as particulate embolic agents for TACE. Besides, new insights into the liquid metals-based multifunctional and flexible embolic agents were highlighted. The current development routes and future outlooks of these micro/nano embolic materials were also presented to promote advancement in the field.

Transarterial chemoembolization versus surgical resection for giant hepatocellular carcinoma under the different status of capsule: a retrospective study. Transl Cancer Res 2022; 11:4359-4372. [PMID: 36644188 PMCID: PMC9834591 DOI: 10.21037/tcr-22-2473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Accepted: 12/12/2022] [Indexed: 12/30/2022]
Abstract
Background As an independent risk factor for the recurrence of hepatocellular carcinoma (HCC), the capsule has not been investigated in giant HCC (HCC ≥10 cm in diameter). In addition, whether the first line treatment for giant HCC should be surgery or transarterial chemoembolization (TACE) remains controversial. The aim of this study was to investigate the influence of tumor capsule on the prognosis of patients with giant HCC, and to compare the prognosis between surgical resection and TACE in giant HCC patients under different status of capsule to better inform surgeons. Methods A retrospective review was conducted of all patients (n=83) who had been diagnosed with giant HCC and undergone surgical resection or TACE in the Affiliated Lihuili Hospital, Ningbo University, from January 2012 to December 2020. Among those who underwent surgical resection, overall survival (OS) and progression-free survival (PFS) were compared between patients with a complete capsule and with either an incomplete or no capsule. In patients with an incomplete/no capsule, survival outcomes were also compared between surgical resection and TACE. Prognostic factors for OS and PFS were analyzed in patients who underwent surgical resection. Results In our study, 30 surgical patients had a complete capsule (Group 1), 33 surgical patients had an incomplete/no capsule (Group 2); 20 patients who had undergone TACE had an incomplete/no capsule (Group 3). The patient demographics were comparable, expect for liver segment invasion and tumor number, which suggested these 2 factors were related with capsule. Median OS was 39 months in Group 1, 27 months in Group 2, and 10 months in Group 3. Median PFS was 17 months in Group 1, 17 months in Group 2, and 7.5 in Group 3. There were significant statistical differences in OS and PFS between Group 1 and Group 2 (P=0.036; P=0.025). In patients who underwent surgical resection surgical time, liver segments invasion, and capsule were the independent risk factor for OS. Conclusions In giant HCC patients, complete tumor capsule could take a better long-term outcomes than incomplete or no tumor capsule. In addition, if possible, such patients should opt for surgical resection to obtain a better prognosis.

Preoperatively predicting early response of HCC to TACE using clinical indicators and MRI features. BMC Med Imaging 2022; 22:176. [PMID: 36207686 PMCID: PMC9540694 DOI: 10.1186/s12880-022-00900-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Accepted: 09/12/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND We aimed to evaluate the value of using preoperative magnetic resonance imaging (MRI) features and clinical indicators to predict the early response of hepatocellular carcinoma (HCC) to transcatheter arterial chemoembolization (TACE). We also aimed to establish a preoperative prediction model. METHODS We retrospectively reviewed data of 111 patients with HCC who underwent magnetic resonance imaging (MRI) before the first TACE and underwent MRI or computed tomography between 30 and 60 days after TACE. We used the modified response evaluation criteria in solid tumors for evaluating the TACE response. We used univariate and multivariate logistic regression analyses to identify independent predictors based on MRI features and clinical indicators. Moreover, receiver operating characteristic (ROC) curve analyses were performed to assess the diagnostic performance of the prediction model and each independent predictor. RESULTS Among the 111 included patients, 85 were men (76.6%). Patient age was 31-86 years (average age, 61.08 ± 11.50 years). After the first treatment session, 56/111 (50.5%) patients showed an objective response (complete response + partial response), whereas the remaining showed non-response (stable disease + local progressive disease). In the univariate analysis, we identified irregular margins, number of nodules, and satellite nodules as predictors of early objective response. However, in the multivariate logistic regression analysis, irregular margins, number of nodules and pretreatment platelet were identified as the independent predictors of early objective response. A combined prediction model was then established, which factored in irregular margins, the number of nodules, and the pretreatment platelet count. This model showed good diagnostic performance (area under the ROC curve = 0.755), with the sensitivity, specificity, positive predictive value, and negative predictive value being 78.6%, 69.1%, 72.1%, and 76.0%, respectively. CONCLUSIONS Irregular margins, the number of nodules and the pretreatment platelet count are independent predictors of the early response of HCC to TACE. Our clinical combined model can provide a superior predictive power to a single indicator.

Abstract
Hepatocellular carcinoma (HCC) is a leading cause of cancer death worldwide and within the United States. Liver transplant or partial liver resection is the definitive treatment of choice for HCC; however, the majority of cases are detected in advanced stages due to its early-stage asymptomatic nature, often precluding surgical treatment. Locoregional therapy plays an essential role in HCC management, including curative intent, as a bridge to transplant, or in some cases palliative therapy. Radiologists play a critical role in assessing tumor response following treatment to guide further management that may potentially impact transplantation eligibility; therefore, it is important for radiologists to have an understanding of different locoregional therapies and the variations of imaging response to different therapies. In this review article, we outline the imaging response to ablative therapy (AT), transarterial chemoembolization (TACE), selective internal radiation therapy (SIRT), and stereotactic body radiation therapy (SBRT). We will also briefly discuss the basic concepts of these locoregional therapies. This review focuses on the imaging features following locoregional treatment for hepatocellular carcinoma following AT, TACE, SIRT, and SBRT.

Radiofrequency ablation combined with transarterial chemoembolization in treatment of hepatocellular carcinoma adjacent to the second hepatic hilus. Abdom Radiol (NY) 2022; 47:423-430. [PMID: 34635940 PMCID: PMC8776660 DOI: 10.1007/s00261-021-03304-4] [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: 06/27/2021] [Revised: 09/25/2021] [Accepted: 09/27/2021] [Indexed: 12/17/2022]
Abstract
Purpose To explore the efficacy and safety of using radiofrequency ablation (RFA) combined with transarterial chemoembolization (TACE) for treating hepatocellular carcinoma (HCC) adjacent to the second hepatic hilus. Methods Between February 2011 and June 2013, 17 patients with HCC underwent combination therapy of TACE and RFA under DSA and CT guidance at our institution. The 17 patients had a total of 23 hepatic tumors, 17 of which were adjacent to the second hepatic hilus. Results TACE combined with RFA was performed successfully in all 17 patients with no mortalities or major morbidities. During the 1-month follow-up, tumors of 15 patients (88.2%) were completely ablated after one therapy session and 2 patients had detectable tumor residue. During the follow-up time period (range 6–52 months), local tumor progression developed in 1 patient (1/17, 5.9%) and both local tumor progression and new tumors appeared in 1 patient (1/17, 5.9%). Also, new tumors developed in the untreated portions of the liver in 8 patients (8/17, 47.1%). No distant metastasis was found. Of the 17 patients, 6 (35.3%) died due to tumor progression (3/17, 17.6%), liver failure (2/17, 11.8%), or massive hemorrhage of the gastrointestinal tract (1/17, 5.9%). The overall survival rates were 94.1% (16/17), 82.4% (14/17), and 61.8% (11/17) at 12, 18, and 24 months, respectively, and the median survival time was 25 months (95% CI 18–27). Conclusion Treatment using combination of TACE and RFA is an effective and safe therapeutic strategy for treating HCC with tumor(s) adjacent to the second hepatic hilus.

Clinical practice of transarterial chemoembolization for hepatocellular carcinoma: consensus statement from an international expert panel of International Society of Multidisciplinary Interventional Oncology (ISMIO). Hepatobiliary Surg Nutr 2021; 10:661-671. [PMID: 34760969 DOI: 10.21037/hbsn-21-260] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Accepted: 08/02/2021] [Indexed: 12/12/2022]
Abstract
Importance Transarterial chemoembolization (TACE) has been associated with a wide range of practice variations for hepatocellular carcinoma (HCC) between the East and the West. This considerable ambiguity may lead to the heterogeneous quality in treatment and have a negative impact on the role of TACE in the overall multidisciplinary HCC treatment system. Objective It may be a good start to establish a guideline worldwide to have this consensus from experts who represent east and west, although it does not cover all aspects of TACE. Evidence Review An international expert panel on TACE is convened to cluster the expert's opinions and summary a standard consensus. This panel committee consist of leading physicians in TACE on HCC from USA, France, Japan, Singapore, Korea, China, and so on. The first-round face-to-face consensus meeting was held during in Nanjing, China in October 2019. The second-round conference for revision of the consensus was held during the Annual Meeting of Chinese College of Interventionalists in August 2020 by a hybrid format of a Webinar and roundtable meeting. After several on-line revisions, the final manuscript was approved by all members of the panel in June 2021. Findings The consensus statements were organized into the following categories: patients' selection, performing the procedure, TACE outcomes, repeat TACE, TACE failure/refractory, and TACE-based combination treatments. Conclusions and Relevance for Reviews More and more evidences have showed the better outcomes with strategy of combined TACE with other local therapies such as ablations. The most-recently developing strategy of combined TACE with PD-1/PD-L1 plus tyrosine kinase inhibitor (TKI) agents has shined a light to the HCC patients, especially to those with high risk of tumor recurrence after treatment or TACE failure/refractory.

Transarterial chemoembolization as a part of multi-modality treatment with drug-eluting beads for locally advanced breast cancer: A case report. Radiol Case Rep 2021; 16:3383-3388. [PMID: 34504630 PMCID: PMC8411206 DOI: 10.1016/j.radcr.2021.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 08/03/2021] [Accepted: 08/03/2021] [Indexed: 11/28/2022] Open
Abstract
Locally advanced breast cancer (LABC) is generally treated with combined-modality therapy including systemic chemotherapy, surgery, radiotherapy, and targeted therapy due to its nature of rapid onset of metastatic disease and poor prognosis. In this case report, we present a 61-year-old female who suffered from a huge protruding breast mass (16.2cm) with superficial ulcerative wound noted for three months. LABC was diagnosed via core needle biopsy and PET-CT examination. Initially, she received combined systemic chemotherapy, hormone therapy and radiation therapy; however, severe necrosis caused rupture in part of the breast mass and extensive wound discharge resulting in difficulty in wound care and prolonged disease course. Trans-arterial chemoembolization with drug-eluting beads (DEB-TACE) was applied as a part of combined-modality therapy for shortening the time before surgery. HepaSphere (as one of the DEB) loaded with high dose of epirubicin (total 80mg) was infused intra-arterially due to the nature of slow-releasing effect and longer duration of ischemic effect. Shortly after DEB-TACE following in about 40 days, surgery was smoothly performed. Post-operative adjuvant target therapy and adjuvant chemotherapy with taxane were administered. There was no evidence of local recurrence or distal metastases after 9 months of follow-up. It is suggested that performing DEB-TACE prior to surgery becomes a part of multimodality treatment of LABC to achieve better local control, better wound care and shortened treatment course.

Efficacy of apatinib in patients with sorafenib-transarterial chemoembolization refractory hepatocellular carcinoma: a retrospective study. Hepatol Int 2021; 15:1268-1277. [PMID: 34415515 DOI: 10.1007/s12072-021-10198-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 04/23/2021] [Indexed: 01/20/2023]
Abstract
PURPOSE To investigate the efficacy of sequential apatinib treatment in patients with unresectable hepatocellular carcinoma (HCC) refractory to sorafenib-transarterial chemoembolization (TACE). MATERIALS AND METHODS This respective study was conducted on 95 consecutive patients with sorafenib-TACE-refractory unresectable HCC in our center from January 2014 to December 2019. According to the response to sorafenib-TACE treatment and the subsequent management, the eligible patients were assigned into three groups: sorafenib-TACE (ST) group, sorafenib-TACE-apatinib (STA) group, and sorafenib-TACE-supportive care (STS) group. The differences in overall survival (OS) and tumor response were compared among the three groups. Risk factors related to prognosis were analyzed. RESULTS A total of 58 patients were enrolled in the study, with 11, 15, and 28 patients in ST, STA, and STS group, respectively. The median OS of the STA group was significantly improved when compared with the STS group, either from the start of sorafenib-TACE resistance or the initiation of sorafenib-TACE therapy (14.0 versus 4.0 months, p = 0.003; 19.0 versus 9.0 months, p < 0.001; respectively). Additionally, from the start of sorafenib-TACE treatment, the median OS of the STA group was longer than that of the ST group without statistical difference (19.0 versus 15.0 months, p = 0.28), so did the comparison of median OS between the ST group and the STS group (15.0 versus 9.0 months, p = 0.06). Extrahepatic metastases were an independent risk factor for poor prognosis. CONCLUSION In patients with sorafenib-TACE-refractory HCC, subsequent apatinib treatment significantly improved the OS when compared with supportive care, and produced comparative outcomes with those sorafenib-TACE responders.

[PMID: 33386908 DOI: 10.1007/s00261-020-02877-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 11/14/2020] [Accepted: 11/18/2020] [Indexed: 12/13/2022]
Abstract
PURPOSE We aimed to assess the safety and efficacy of transarterial chemoembolization (TACE) with doxorubicin-loaded CalliSpheres® beads (DEB-TACE) for the treatment of patients with inoperable or recurrent colorectal cancer (CRC). METHODS This retrospective study recruited 12 consecutive patients with histology confirmation of CRC who received DEB-TACE between August 2017 and April 2020. There were 9 male and 3 female, with a mean age 62.5 ± 14.9 (range 29-84). Patients' characteristics, medical imaging data, complications and DEB-TACE procedure were retrospectively reviewed. The disease control rate was defined as the sum of complete response, partial response and stable disease. RESULTS DEB-TACE was successfully performed in all patients. All patients showed local disease control 1 month after DEB-TACE. Disease control rates were 90.9% and 70.0% at 3 and 6 months after DEB-TACE procedure, respectively. Disease-free interval was 11.0 to 81.8 months. Five patients (41.7%) received prior chemotherapy treatments. No severe complications or procedure-related deaths were observed. The median overall survival was 15.9 months, and median progression-free survival was 13.4 months. CONCLUSION DEB-TACE is a safe and effective treatment and could be a option for patients with inoperable or recurred CRC.

Clinical outcomes of doxorubicin-eluting CalliSpheres® beads-transarterial chemoembolization for unresectable or recurrent esophageal carcinoma. BMC Gastroenterol 2021; 21:231. [PMID: 34020608 PMCID: PMC8139071 DOI: 10.1186/s12876-021-01816-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 05/16/2021] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND The clinical outcomes of drug-eluting beads transarterial chemoembolization (DEB-TACE) with doxorubicin-loaded CalliSpheres® beads for patients with unresectable or recurrent esophageal carcinoma have not been reported. The aim of this study is to study the clinical outcomes of DEB-TACE for patients with unresectable or recurrent esophageal carcinoma. METHODS This retrospective study enrolled 21 patients (15 men; mean age 68.7 ± 9.7; range 46-86 years) with unresectable or recurrent esophageal carcinoma received DEB-TACE between July 2017 and September 2020. Patient characteristic data, imaging findings, complications and DEB-TACE procedure were reviewed. The primary endpoints, disease control rate (DCR) and objective response rate (ORR), were calculated. The secondary endpoints were overall survival rate and progression-free survival (PFS). RESULTS Twenty-two sessions of DEB-TACE were performed in 21 patients. The technical success rate was 100%; without sever adverse events or procedure-related deaths. All patients received transarterial chemotherapy infusion with raltitrexed or oxaliplatin. The median follow-up period was 3.6 months (interquartile range, IQR 1.5-9.4 months). ORR and DCR were 42.9 and 85.7%, 28.6 and 71.4%, 20.0 and 40.0% respectively at 1-, 3-, and 6-months after DEB-TACE. The median PFS was 6.0 months, and the 3-, 6- and 12-month PFS rates were 68.2%, 45.5 and 0.0%, respectively. The median overall survival was 9.4 months, and the 3-, 6- and 12-month overall survival rates were 75.5%, 55.0 and 13.8%, respectively. CONCLUSIONS To our knowledge, this is the first study reports outcomes of DEB-TACE with doxorubicin-loaded CallSpheres bead treatment in the management of patients with unresectable or recurrent esophageal carcinoma. According to our results, this is a safe and feasible treatment modality that may be considered among the options for the treatment of these patients.

Transarterial Chemoembolization of Hepatocellular Carcinoma Using Radiopaque Drug-Eluting Embolics: Impact of Embolic Density and Residual Tumor Perfusion on Tumor Recurrence and Survival. Cardiovasc Intervent Radiol 2021; 44:1403-1413. [PMID: 34021375 PMCID: PMC8382629 DOI: 10.1007/s00270-021-02858-6] [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] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 04/24/2021] [Indexed: 12/23/2022]
Abstract
Purpose To evaluate the value of dual-phase parenchymal blood volume (PBV) C-arm mounted cone-beam-CT (CBCT) to enable assessment of radiopaque, doxorubicin-loaded drug-eluting embolics (rDEE) based on the visual degree of embolization, embolic density and residual tumor perfusion as early predictors for tumor recurrence after transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC).
Material and Methods Thirty patients (50 HCCs) were prospectively enrolled, underwent cross-sectional imaging before and after TACE using 100–300 µm rDEE and had regular follow-up examinations. Directly before and after the TACE procedure, PBV-CBCT was acquired. The response was evaluated and compared to visual degree of embolization (DE) and embolic density (ED) of rDEE deposits, as well as the presence of residual tumor perfusion (RTP) derived from PBV-CBCT. Outcome was assessed by mid-term tumor response applying mRECIST and patient survival after 12 months.
Results RTP was detected in 16 HCCs and correlated negatively with DE (p = .03*) and ED (p = .0009*). The absence of RTP significantly improved lesion-based mid-term response rates regarding complete response (CR, 30/34 (88%) vs 2/16 (12.5%), p = .0002*), lesion-based complete response rate was 75% (21/28) for DE ≥ 50% vs. 50% (11/22) for DE < 50% (p = .08) and 82% (27/33) for ED ≥ 2 vs. 29% for ED < 2 (5/17), p = .005*). Thirteen patients were treated with re-TACE within 12 months, 11 of which had shown RTP. 12-month survival rate was 93%. Conclusion Residual tumor perfusions as assessed by PBV-CBCT during rDEE-TACE proved to be the best parameter to predict mid-term response. “Level of Evidence: Level 3” Supplementary Information The online version contains supplementary material available at 10.1007/s00270-021-02858-6.

Influence of postoperative adjuvant transarterial chemoembolization on the prognosis of early-stage intrahepatic cholangiocarcinoma: a single center study. ANNALS OF PALLIATIVE MEDICINE 2021; 10:3673-3683. [PMID: 33691434 DOI: 10.21037/apm-20-1337] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 12/28/2020] [Indexed: 11/06/2022]
Abstract
BACKGROUND The effectiveness of postoperative adjuvant transarterial chemoembolization (TACE) on survival and recurrence in tumor-node-metastasis (TNM) stage I intrahepatic cholangiocarcinoma (ICC) after radical resection remains unclear. This study aimed to compare overall survival (OS) and recurrence-free survival (RFS) in TNM stage I ICC patients with and without postoperative TACE. METHODS A retrospective cohort study was conducted on TNM stage I ICC patients who had undergone R0 resections with curative intent in Shanghai Eastern Hepatobiliary Surgery Hospital from January 2012 to December 2016. A total of 269 patients were divided into two groups: (I) 35 patients who received postoperative TACE and (II) 234 patients no TACE. Staging was performed according to the 8th edition of American Joint Committee on Cancer (AJCC) TNM staging system. The tumor-related RFS and OS were estimated by the Kaplan-Meier method. Cox proportional regression model was employed to evaluate the prognosis between the two groups. RESULTS In all patients, the median OS was 66.8 months. After R0 resection, adjuvant TACE could not improve the survival of TNM stage I patients, and the OS of the TACE group was not better than that of the non-TACE group (P=0.7070). In addition, in the TACE group, the recurrence rate of TNM stage I ICC patients was statistically significantly higher than that of the non-TACE group (P=0.0328). Multivariable analysis revealed that adjuvant TACE was an independent predictor of worse RFS (HR: 1.88, 95% CI: 1.21-2.93). CONCLUSIONS Adjuvant TACE after radical surgery failed to prolong the OS and potentially delay recurrence for patients with TNM Stage I ICC. Adjuvant TACE might not be suitable for patients with TNM Stage I ICC.

Abstract
BACKGROUND AND AIM The transcriptional co-activator Yes-associated protein-1 (YAP1) has been implicated as an oncogene and is overexpressed in different kinds of human cancers, especially hepatocellular carcinoma (HCC). However, the role of YAP1 has not been reported in residual/recurrent HCC after transarterial chemoembolization (TACE). Our aim is to determine whether YAP1 is overexpressed in the residual/recurrent HCC after TACE. METHODS A total of 105 tumor tissues from 71 patients including 30 cases of primary HCC without prior treatment, 35 cases of residual/recurrent HCC post TACE, and 6 cases of hepatoblastoma were included in the immunohistochemical study. YAP1 immunoreactivity was blindly scored as 0, 1+, 2+ or 3+ in density and percentages of positive cells. RESULTS About 33.3% (10/30) of primary HCC without prior treatment showed 2+ of YAP1 immunoreactivity. While 82.8% (29/35) of residual/recurrent HCCs after TACE treatment displayed 2-3+ of YAP1 immunoreactivity, which was significantly higher compared to primary HCC without prior treatment (P = 0.0002). YAP1 immunoreactivity was moderately to strongly positive (2-3+) in 100% of the hepatoblastoma, particularly in the embryonal components (3+ in 100% cases). CONCLUSIONS YAP1 is significantly upregulated in the residual/recurrent HCCs post TACE treatment, suggesting that YAP1 may serve as a sensitive diagnostic marker and a treatment target for residual/recurrent HCC post TACE.

Abstract
OBJECTIVE There is no standardized and objective method for determining the optimal treatment endpoint (sub-stasis) during transarterial embolization. The objective of this study was to demonstrate the feasibility of using a quantitative digital subtraction angiography (qDSA) technique to characterize intra-procedural changes in hepatic arterial blood flow velocity in response to transarterial embolization in an in vivo porcine model. MATERIALS AND METHODS Eight domestic swine underwent bland transarterial embolizations to partial- and sub-stasis angiographic endpoints with intraprocedural DSA acquisitions. Embolized lobes were assessed on histopathology for ischemic damage and tissue embolic particle density. Analysis of target vessels used qDSA and a commercially available color-coded DSA (ccDSA) tool to calculate blood flow velocities and time-to-peak, respectively. RESULTS Blood flow velocities calculated using qDSA showed a statistically significant difference (p < 0.01) between partial- and sub-stasis endpoints, whereas time-to-peak calculated using ccDSA did not show a significant difference. During the course of embolizations, the average correlation with volume of particles delivered was larger for qDSA (- 0.86) than ccDSA (0.36). There was a statistically smaller mean squared error (p < 0.01) and larger coefficient of determination (p < 0.01) for qDSA compared to ccDSA. On pathology, the degree of embolization as calculated by qDSA had a moderate, positive correlation (p < 0.01) with the tissue embolic particle density of ischemic regions within the embolized lobe. CONCLUSIONS qDSA was able to quantitatively discriminate angiographic embolization endpoints and, compared to a commercially available ccDSA method, improve intra-procedural characterization of blood flow changes. Additionally, the qDSA endpoints correlated with tissue-level changes.

Abstract
Background Sorafenib has been recommended as the first-line treatment and shown to prolong median overall survival (OS) of patients with advanced unresectable hepatocellular carcinoma (HCC). Recently, a growing amount of research has supported the application of transarterial chemoembolization (TACE) in patients with advanced-stage HCC. The aim of this study was to compare the outcomes of TACE and sorafenib and identify the prognostic factors related to OS for Barcelona Clinic Liver Cancer (BCLC) stage C patients with PS 1 but without vascular invasion or extrahepatic spread. Methods A total of 323 consecutive patients in BCLC stage C with PS 1 but without vascular invasion or extrahepatic spread were enrolled in this retrospective study. Survival analyses were performed using the Kaplan-Meier analysis, and the statistical differences between the TACE and sorafenib groups were examined by the log-rank test. Univariate and multivariate Cox regression analyses were performed to investigate the prognostic factors for OS. Results Based on the Kaplan-Meier curves, patients treated with TACE showed a better OS than those undergoing sorafenib, with respective OS at 1, 3, and 5 years (67.7%, 41.5%, 23.2% vs. 55.6%, 29.6%, 4.8%; log-rank P=0.002). The univariate analysis indicated that tumor size, tumor number, and treatment method, along with platelet (PLT), white blood cell (WBC), and α-fetoprotein (AFP) count, were associated with OS. The multivariate analysis demonstrated that tumor size, tumor number, and treatment method were significant prognostic factors for OS. According to the subgroups analyses based on the tumor size and tumor number, there were significant differences in OS among overall subsets between TACE and sorafenib therapy. Conclusions TACE provided better prognostic performance than sorafenib and should be suggested as an alternative treatment modality to sorafenib for BCLC stage C patients with PS 1 but without vascular invasion or extrahepatic spread.

Retrospective analysis of the immunogenic effects of intra-arterial locoregional therapies in hepatocellular carcinoma: a rationale for combining selective internal radiation therapy (SIRT) and immunotherapy. BMC Cancer 2020; 20:135.

Abstract
Background Immunotherapy represents a promising option for treatment of hepatocellular carcinoma (HCC) in cirrhotic patients but its efficacy is currently inconsistent and unpredictable. Locoregional therapies inducing immunogenic cell death, such as transarterial chemoembolization (TACE) or selective internal radiation therapy (SIRT), have the potential to act synergistically with immunotherapy. For the development of new approaches combining locoregional treatments with immunotherapy, a better understanding of the respective effects of TACE and SIRT on recruitment and activation of immune cells in HCC is needed. To address this question, we compared intra-tumor immune infiltrates in resected HCC after preoperative treatment with TACE or SIRT. Methods Data fromr patients undergoing partial hepatectomy for HCC, without preoperative treatment (SURG, n = 32), after preoperative TACE (TACE, n = 16), or preoperative SIRT (n = 12) were analyzed. Clinicopathological factors, tumor-infiltrating lymphocytes (TILs), CD4+ and CD8+ T cells, and granzyme B (GZB) expression in resected HCC, and postoperative overall and progression-free survival were compared between the three groups. Results Clinicopathological and surgical characteristics were similar in the three groups. A significant increase in TILs, CD4+ and CD8+ T cells, and GZB expression was observed in resected HCC in SIRT as compared to TACE and SURG groups. No difference in immune infiltrates was observed between TACE and SURG patients. Within the SIRT group, the dose of irradiation affected the type of immune infiltrate. A significantly higher ratio of CD3+ cells was observed in the peri-tumoral area in patients receiving < 100 Gy, whereas a higher ratio of intra-tumoral CD4+ cells was observed in patients receiving > 100 Gy. Postoperative outcomes were similar in all groups. Irrespective of the preoperative treatment, the type and extent of immune infiltrates did not influence postoperative survival. Conclusions SIRT significantly promotes recruitment/activation of intra-tumor effector-type immune cells compared to TACE or no preoperative treatment. These results suggest that SIRT is a better candidate than TACE to be combined with immunotherapy for treatment of HCC. Evaluation of the optimal doses for SIRT for producing an immunogenic effect and the type of immunotherapy to be used require further evaluation in prospective studies.

Abstract
Background Accurate and early diagnosis of residual tumors or intrahepatic recurrences after TACE is critically needed for determining the success of treatments and for guiding subsequent therapeutic planning. This meta-analysis was performed to assess the efficacy of diffusion weighted imaging (DWI) with the quantitative apparent diffusion coefficient (ADC) value in diagnosing residual or recurrent hepatocellular carcinoma after transarterial chemoembolization (TACE). Materials and methods A comprehensive literature search of PubMed, Embase, Web of Science, Scopus and the Cochrane Library database, from inception to July 2019, was conducted to select original studies on diagnosing residual or recurrent HCCs after TACE using DWI sequence with its ADC value. Two researchers independently chose study, extracted data, conducted meta-analysis, and evaluated methodological quality according to Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. Results Twelve studies comprising 624 patients and 712 tumors were finally included. The pooled sensitivity, specificity and AUC value of DWI in diagnosing residual or recurrent HCCs after TACE were 85% (95%CI: 74–92%), 83% (95%CI: 75–88%) and 0.90 (95%CI: 0.87–0.92), respectively. Residual or recurrent HCCs have significantly lower ADC value than necrotic tumors (MD = -0.48, 95%CI: − 0.69~ − 0.27, P < 0.01). Conclusion This study demonstrated that DWI performed better in diagnosing residual or recurrent HCCs after TACE, and ADC value may serve as alternatives for further evaluation of residual or recurrent leisions in HCC patients after TACE.

Abstract
Background This study aimed to compare the safety and efficacy of transradial access (TRA) with transfemoral access (TFA) chemoembolization in treatment of hepatocellular carcinoma (HCC). Methods HCC patients who were late for curative treatment on initial diagnosis or HCC patients who had undergone one or several rounds of transarterial chemoembolization (TACE) were enrolled. The clinical and angiographic characteristics, the procedure related details, and the follow-up data from patients who underwent TRA and TFA were analyzed and compared. Results In total, 112 patients undergoing 160 TRA-TACE and 107 patients undergoing 163 TFA-TACE were included. The technical success rate of TRA was 95.0% and that of TFA was 98.8% (P=0.102). In the TFA-TACE group, 5.5% of cases suffered access site-related complications, including 6 with minor bleeding and 3 with severe bleeding or pseudoaneurysm. In the TRA-TACE group, 1.9% of cases underwent crossover to femoral access for selective cannulation failure. The rate of radial artery occlusion (RAO) was 2.7% (3 of 112 patients), and none of the RAO patients suffered paresthesia, pain at the site of occlusion, hand function loss or distal ischemia. Comparing patients with/without access site-related complications in the TFA-TACE group, there was a statistical difference in patient age and in the percentage of patient with a PT time >15 s (72.6% vs. 57.1%, P<0.001; 44.4% vs. 11.7%, P=0.022). Conclusions TRA is a safe and effective method for patients undergoing TACE. Compared with TFA, TRA may reduce the occurrence of access site-related bleeding and vascular complications. TRA-TACE may especially benefit older patients or those with a longer prothrombin time (PT).

Abstract
Background Conventional transarterial chemoembolization (c-TACE) is a common treatment for unresectable hepatocellular carcinoma (HCC). It is associated with increased overall survival (OS) when compared to conservative management. The purpose of this study is to analyze all c-TACE with mitomycin in patients with HCC at a single institution to determine safety, efficacy, and prognostic factors in a long-term follow-up. Methods Retrospective analysis of patients with HCC treated only with c-TACE with Mitomycin between 2007 and 2012. Efficacy was determined by OS at 1, 3, and 5 years, censored by date of death or last known follow-up. Treatment response was assessed according to mRECIST criteria and the degree of lipiodol uptake by the lesions was assessed by CT at 1-month follow-up. Prognostic factors were analyzed by multiple linear regression analysis, significance levels set at 0.05. Results A total of 60 patients were identified. OS rate at 1, 3 and 5 years was 72.1%, 47.8% and 39.3%, respectively. Median OS was 15 months. Tumor response by mRECIST criteria was complete; objective response, defined as combination of complete response (CR) and partial response (PR) patients, was 76%. When stratified by tumor response, risk of death in patients with progressive disease in 5 years was significantly higher compared to patients with objective response [hazard ratio (HR): 2.531, 95% confidence interval (CI): 1.110-5.778, P=0.0273]. Lipiodol uptake analysis was available in 51 patients; there was no statistically significant difference in OS in patients with higher lipiodol uptake compared to less uptake (<50% versus >50% uptake; HR: 0.713, 95% CI: 0.316-1.611, P=0.4161]. Conclusions c-TACE with mitomycin was effective and safe in this long-term follow-up study. Risk of death was significantly higher in patients without objective tumor response.

Post Locoregional Therapy Treatment Imaging in Hepatocellular Carcinoma Patients: A Literature-based Review. J Clin Transl Hepatol 2018; 6:189-197. [PMID: 29951364 PMCID: PMC6018307 DOI: 10.14218/jcth.2017.00059] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2017] [Revised: 12/14/2017] [Accepted: 12/22/2017] [Indexed: 12/19/2022] Open
Abstract
Imaging plays a crucial role in the diagnosis of hepatocellular carcinoma (HCC) as well as in determining treatment efficacy, or complications, following therapy. Unlike other cancers, HCC is most commonly treated by locoregional therapies (LRTs) such as thermal ablation, transarterial chemoembolization, and transarterial radioembolization. These treatments can lead to changes on imaging that make determination of residual/recurrent disease difficult. This literature-based review discusses the expected postimaging findings following LRT.

Abstract
CLINICAL/METHODICAL ISSUE Focal liver lesions are common incidental findings in abdominal ultrasound diagnostics. STANDARD RADIOLOGICAL METHODS Characterization of focal liver lesions solely based on b‑mode and color duplex is not feasible in all cases. METHODICAL INNOVATIONS Using contrast-enhanced ultrasound (CEUS) it is possible to dynamically visualize the vascularization of focal liver lesions, which enables the characterization of benign and malignant liver tumors. The advantages of CEUS are that ultrasound contrast media do not show renal, hepatic or cardiac toxicity and do not influence the thyroid gland. The approach by fusion of CEUS and contrast-enhanced cross-sectional imaging combines the advantages of both imaging modalities. PERFORMANCE Using CEUS focal liver lesions can be characterized with a diagnostic accuracy greater than 90%. ACHIEVEMENTS The use of CEUS has become an important imaging modality to evaluate unclear liver lesions. PRACTICAL RECOMMENDATIONS The use of CEUS provides vital information as a supplement to cross-sectional imaging and it has become an important tool in therapy planning, control and monitoring of malignant liver lesions.

A novel combined systemic inflammation-based score can predict survival of intermediate-to-advanced hepatocellular carcinoma patients undergoing transarterial chemoembolization. BMC Cancer 2018; 18:216.

Abstract
BACKGROUND There is currently limited information regarding the prognostic ability of the dNLR-PNI (the combination of the derived neutrophil-to-lymphocyte ratio [dNLR] and prognostic nutritional index [PNI]) for hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of the dNLR-PNI in patients with intermediate-to-advanced HCC after transarterial chemoembolization (TACE). METHODS A total of 761 HCC patients were enrolled in the study. The dNLR-PNI was retrospectively calculated in these patients, as follows: patients with both an elevated dNLR and a decreased PNI, as determined using the cutoffs obtained from receiver operating characteristic curve analysis, were allocated a score of 2, while patients showing one or neither of these alterations were allocated a score of 1 or 0, respectively. RESULTS During the follow-up period, 562 patients died. Multivariate analysis suggested that elevated total bilirubin, Barcelona Clinic Liver Cancer C stage, repeated TACE, and dNLR-PNI were independently associated with unsatisfactory overall survival. The median survival times of patients with a dNLR-PNI of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 22.5-39.5), 16.0 (95% CI 12.2-19.7) and 6.0 (95% CI 4.8-7.2) months, respectively (P < 0.001). CONCLUSIONS The dNLR-PNI can predict the survival outcomes of intermediate-to-advanced HCC patients undergoing TACE, and should be further evaluated as a prognostic marker for who are to undergo TACE treatment.

Downstaging for hepatocellular cancer: harm or benefit? Transl Gastroenterol Hepatol 2017; 2:106. [PMID: 29354763 DOI: 10.21037/tgh.2017.11.18] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Accepted: 11/28/2017] [Indexed: 12/11/2022] Open
Abstract
Downstaging of hepatocellular carcinoma (HCC) to enable liver transplantation has become an area of intense interest and research. It may allow a curative option in patients outside widely accepted transplantation criteria, with outcomes that, in some studies, are comparable to transplantation for patients within criteria. There have been conflicting opinions on the best downstaging protocols, criteria for downstaging eligibility and for assessment of response. We therefore aimed to review the literature and evidence for downstaging, as well as considering its drawbacks. CONCLUSION Pooled analyses have suggested success in down staging in about half of patients treated, but with higher recurrence rates than patients initially within transplantation criteria. Studies with strict inclusion criteria and mandatory waiting time before transplantation reported survival equivalent to patients who did not require downstaging. In carefully selected patients, there is a role for down staging to provide the chance of transplantation and cure, with acceptable outcomes. Further multi center, well-designed studies are required to clarify who will mostly benefit. Until such data is available, downstaging criteria should be stated within transplantation programs and relevant decisions should be discussed by multidisciplinary teams.

Abstract
PURPOSE To investigate the association between pretransplant intra-arterial liver-directed therapy (IAT) for hepatocellular carcinoma (HCC) and hepatic arterial complications (HAC) in orthotopic liver transplantation (OLT) [namely hepatic artery thrombosis (HAT) and/or the need for hepatic arterial conduit]. METHODS A total of 175 HCC patients (mean age: 60 years) underwent IAT with either transarterial chemoembolization or yttrium-90 (90Y) transarterial radioembolization prior to OLT between 2003 and 2013. A matched control cohort of 159 HCC patients who underwent OLT without prior IAT was selected. Incidence of HAC in both cohorts was investigated. The categorical differences between both cohorts were calculated by chi-square test. RESULTS Among the 175 patients (chemoembolization, n = 82; radioembolization, n = 93), 8 (5%) required conduits due to HA disease (chemoembolization, n = 6; radioembolization, n = 2), 3 (2%) developed HAT (chemoembolization, n = 2; radioembolization, n = 1). Eleven of 175 patients (6.7%) had HAC. Of the 159 control patients, 6 (4%) needed conduits for HA disease and 3 (2%) developed HAT. Nine of 159 patients (5.7%) had HAC. Chi-square analysis between the IAT cohort and the control group yielded a p value of 0.810. When comparing chemoembolization to radioembolization, p = 0.076 (not significant at p < 0.05). CONCLUSION Although aggressive pretransplant radioembolization and chemoembolization are both utilized in most liver transplant centers, neither appears to increase the risk of peri-transplant hepatic arterial complications in HCC patients.

Abstract
Transarterial chemoembolization (TACE) is a therapeutic procedure often performed for hepatocellular carcinoma (HCC). Local complications, though generally uncommon, can arise from arterial ischemia and local cytotoxicity from the chemotherapeutic delivery. We present a case of acute pancreatitis as a rare complication of the TACE procedure along with a review of literature of this uncommon adverse effect.

Abstract
Transarterial chemoembolization (TACE) is the standard of care for treatment of intermediate hepatocellular carcinoma (HCC), however, key molecules involved in HCC cell survival and tumor metastasis post-TACE remain unclear. CD147 is a member of the immunoglobulin superfamily that is overexpressed on the surface of HCC cells and is associated with malignant potential and poor prognosis in HCC patients. In this study, using an Earle's Balanced Salt Solution medium culture model that mimics nutrient deprivation induced by TACE, we investigated the regulation of CD147 expression on HCC cells under starvation conditions and its functional effects on HCC cell death. During early stages of starvation, the expression of CD147 was considerably upregulated in SMMC7721, HepG2 and HCC9204 hepatoma cell lines at the protein levels. Downregulation of CD147 by specific small interfering RNA (siRNA) significantly promoted starvation-induced cell death. In addition, CD147 siRNA-transfected SMMC7721 cells demonstrated significantly increased levels of both apoptosis and autophagy as compared to cells transfected with control siRNA under starvation conditions, whereas no difference was observed between the two treatment groups under normal culture conditions. Furthermore, silencing of CD147 resulted in a remarkable downregulation of phosphorylated mammalian target of rapamycin (p-mTOR) in starved SMMC7721 cells. Finally, the combined treatment of starvation and anti-CD147 monoclonal antibody exhibited a synergistic HCC cell killing effect. Our study suggests that upregulation of CD147 under starvation may reduce hepatoma cell death by modulating both apoptosis and autophagy through mTOR signaling, and that CD147 may be a novel potential molecular target to improve the efficacy of TACE.

Abstract
Primary liver cancer is the sixth most common cancer overall and the second most common cause of cancer mortality worldwide. Hepatocellular carcinoma accounts for up to 90% of all primary hepatic malignancies and represents a major international health problem. While surgical resection and transplantation are the cornerstone of therapy in early-stage hepatocellular carcinoma, locoregional therapy and sorafenib are beneficial in those with more advanced disease or those who are not surgical candidates. At times, the integration of both surgical and locoregional therapy may be necessary. Hence, hepatocellular carcinoma requires a multidisciplinary approach to determine the most appropriate treatment as well as the timing of various treatments for optimal outcomes.

Comparison of volume perfusion computed tomography and contrast-enhanced ultrasound for assessment of therapeutic effect of transarterial chemoembolization in patients with hepatocellular carcinoma: a preliminary report. Acta Radiol 2016; 57:8-12. [PMID: 25585848 DOI: 10.1177/0284185114566442] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2014] [Accepted: 12/08/2014] [Indexed: 01/16/2023]
Abstract
BACKGROUND Evaluation of transarterial chemoembolization (TACE) by using contrast-enhanced ultrasound (CEUS) and volume perfusion computed tomography (VPCT) as methods that display tumor vascularization. PURPOSE To assess early results of TACE in patients with hepatocellular carcinoma (HCC) using CEUS and VPCT. MATERIAL AND METHODS Twenty patients with HCC underwent CEUS and VPCT in the pre- and post-TACE setting (1 day). Hepatic perfusion index (HPI), arterial liver perfusion (ALP), blood flow (BF), and blood volume (BV) were measured with VPCT. Peak intensity (PI), time-to-peak (TTP), and regional blood flow (RBF) were measured with CEUS. Sensitivity, specificity, negative and positive predictive values, and cutoff values for these parameters were calculated. Immediate tumor response after TACE was classified as responder or non-responder. Results were compared with those at follow-up after 2 and 4 months (FU2mo/FU4mo) following modified RECIST. RESULTS CEUS and VPCT showed comparable immediate post-TACE results in 20/20 cases. Complete response was confirmed in 10/20 patients at FU2mo and in 9/20 at FU4mo. For responders, reduction in HPI, ALP, BV, and BF at day 1 post TACE proved significant (P < 0.001). For non-responders, the course of all VPCT parameters proved non-significant. A cutoff of 40% reduction in HPI and a reduction in ALP of >29.6%, in BV of >41.4%, or in BF of >53.1% was indicative of response according to FU2mo. For responders only, changes in PI (P < 0.001), TTP (P < 0.01), and BF (P < 0.01) proved significant whereas for non-responders, all CEUS parameters proved non-significant. CONCLUSION CEUS performs equally to VPCT for assessment of early response to TACE in HCC by a lesion-by-lesion assessment and showed prognostic value at mid-term.

Abstract
OBJECTIVE Response monitoring of transarterial chemoembolization (TACE) with the help of volume perfusion computed tomography (VPCT) at day one post-TACE and analysis of TACE-impact on tumor and uninvolved liver parenchymal perfusion by using different particles sizes and epirubicin dose. MATERIALS AND METHODS Institutional review board approved this prospective study. VPCT was performed in the baseline, post-interventional (FU1; 24 h post-TACE) and at follow-up (FU2; median, 81 days) in 45 consecutive patients. 100-300 μm (n=17) and 300-500 μm (n=28) drug eluting beads (DEB) using an epirubicin dose of (<=25 vs. >25) were administered. VPCT was performed for 40-s using 80 kV, 100/120 mAs, 64×0.6 mm collimation, 26 consecutive measurements, IV injection (50 ml iodinated contrast), flow rate (5 ml/s). Blood flow (BF), blood volume (BV) and k-trans were registered as average and max values in the tumor. Arterial liver perfusion (ALP), portal-venous perfusion (PVP) and the hepatic perfusion index (HPI) were registered both in tumor and non-involved liver parenchyma. Response to TACE was classified by VPCT as complete (CR), partial (PR) or no response (NR). RESULTS A significant reduction of viable tumor tissue was found in all patients between baseline and FU1 (p<0.001) being independent on particle size and epirubicin dose (p>0.05). PPV/NPV/sensitivity/specificity of post-interventional VPCT (FU1) results for prediction of the mid-term tumor course (FU2) were 100%/70%/76%/100%. There was generally a significant increase of the ALP between baseline and FU1 in the liver parenchyma coupled by a significant subsequent decrease (normalization) of ALP and HPI between FU1 and FU2. CONCLUSION VPCT accurately measures impact of TACE on liver tumor and hepatic parenchymal perfusion. The former proved not to be significantly dependent on particle size and epirubicin dose. There was no persistent perfusion deficit in the liver after TACE.

Abstract
Transarterial chemoembolization (TACE) is the recommended treatment of intermediate stage hepatocellular carcinoma (HCC). Radioembolization with yttrium 90 has overcome the shortcomings of external beam radiation in the treatment of liver cancer. TACE and radioembolization have led to encouraging response, survival, and quality of life outcomes, with reduced toxicity profiles. This result has led to the use of these therapies in patients with hepatic metastases, most commonly from colorectal cancer. This article reviews the current state of the practice of TACE and radioembolization and presents recent scientific data that support their role in the treatment of HCC and hepatic metastatic disease.
