Abstract
BACKGROUND Information regarding the therapeutic effect and outcome of transcatheter arterial embolization (TAE) for hepatic masses is limited in veterinary medicine. HYPOTHESIS/OBJECTIVES To analyze the therapeutic response, outcome (overall survival), and their predictors in dogs that underwent TAE for primary hepatocellular masses. We hypothesized that larger pre-TAE tumors would be associated with worse outcomes. ANIMALS Fourteen client-owned dogs. METHODS Retrospective study. Medical records between 1 September 2016 and 30 April 2022 were reviewed to identify dogs treated with TAE for hepatic masses diagnosed as hepatocellular origin by cytological or histopathological examination. Computed tomography images were compared before and after TAE. The univariate Cox proportional hazards test was performed to assess the associations between variables and survival. Univariate linear regression analysis was performed to assess the associations between variables and the tumor reduction percentage: ([post-TAE volume - pre-TAE volume]/pre-TAE volume) × 100. RESULTS The median survival time was 419 days (95% confidence interval, 82-474). History of intra-abdominal hemorrhage (P = .03) and pre-TAE tumor volume/body weight (P = .009) were significantly associated with overall survival. The mean reduction percentage was -51% ± 40%. Pre-TAE tumor volume/body weight ratio (cm3 /kg; P = .02, correlation coefficient = 0.704) was significantly correlated with the volume reduction percentage. CONCLUSIONS History of intra-abdominal hemorrhage and large pre-TAE tumor volume/body weight ratio could be predictive factors for adverse outcomes after TAE. Pre-TAE tumor volume/body weight ratio could be a predictive factor for therapeutic effect.

Optimizing Loco Regional Management of Oligometastatic Colorectal Cancer: Technical Aspects and Biomarkers, Two Sides of the Same Coin. Cancers (Basel) 2021; 13:2617. [PMID: 34073585 PMCID: PMC8198296 DOI: 10.3390/cancers13112617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 05/21/2021] [Accepted: 05/22/2021] [Indexed: 11/23/2022] Open
Abstract
Colorectal cancer (CRC) is the third most common cancer worldwide and has a high rate of metastatic disease which is the main cause of CRC-related death. Oligometastatic disease is a clinical condition recently included in ESMO guidelines that can benefit from a more aggressive locoregional approach. This review focuses the attention on colorectal liver metastases (CRLM) and highlights recommendations and therapeutic locoregional strategies drawn from the current literature and consensus conferences. The different percutaneous therapies (radiofrequency ablation, microwave ablation, irreversible electroporation) as well as trans-arterial approaches (chemoembolization and radioembolization) are discussed. Ablation margins, the choice of the imaging guidance as well as characteristics of the different ablation techniques and other technical aspects are analyzed. A specific attention is then paid to the increasing role of biomarkers (in particular molecular profiling) and their role in the selection of the proper treatment for the right patient. In conclusion, in this review an up-to-date state of the art of the application of locoregional treatments on CRLM is provided, highlighting both technical aspects and the role of biomarkers, two sides of the same coin.

Safety and Efficacy of Degradable Starch Microspheres Transcatheter Arterial Chemoembolization as a Bridging Therapy in Patients with Early Stage Hepatocellular Carcinoma and Child-Pugh Stage B Eligible for Liver Transplant. Front Pharmacol 2021; 12:634084. [PMID: 33897421 PMCID: PMC8062923 DOI: 10.3389/fphar.2021.634084] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Accepted: 02/19/2021] [Indexed: 12/12/2022] Open
Abstract
In patients with early-stage hepatocellular carcinoma, awaiting liver transplantation, current guidelines by AASLD and ESMO recommend a bridging therapy with a loco-regional treatment to prevent progression outside transplantation criteria. The standard of care in delaying disease progression has been recognized to be the transarterial chemoembolization. Permanent occlusion of tumor feeding vessels has effects on tumour stromal microenvironment by inducing intra- and intercellular signaling processes counteracting hypoxia, such as the release of vascular endothelial growth factor, a promoter of neoangiogenesis, tumour proliferation and metastatic growth. Among chemoembolization interventions, TACE with degradable starch microspheres represents an alternative to conventional cTACE and DEB-TACE and it minimizes detrimental effects on tumour stromal microenvironment, guaranteeing a transient occlusion of tumour feeding arteries and avoiding VEGF overexpression.Between January 2015 and September 2020, 54 consecutive patients with early-stage hepatocellular carcinoma and Child-Pugh stage B, who had undergone DSM-TACE as a bridging therapy while awaiting liver transplantation, were eligible for the study. A total of 154 DSM-TACE was performed, with a mean number of 2.85 procedures per patient. 18 patients (33.3%) succeeded in achieving liver transplantation, with a mean waiting time-to-transplantation of 11.7 months. The cumulative rates of patients still active on the WL at 6 months were about 91 and 93% when considering overall drop-out and tumour-specific drop-out respectively. Overall survival was about 96% at 6 months and 92% at 12 months. 17 patients experienced adverse events after the chemoembolizations. For patients with HCC in the transplant waiting list and within the Child-Pugh B stage, life expectancy may be dominated by the liver dysfunction, rather than by the tumour progression itself. In this population subset, the choice of LRT is critical because LRT itself could become a dangerous tool that is likely to precipitate liver dysfunction to an extent that survival is shortened rather than prolonged. Hence, the current study demonstrates that DSM-TACE is not far from being an ideal LRT, because it has an excellent safety profile, maintaining an efficacy that guarantees a clear advantage on the dropout rate with respect to the non-operative strategy, thus justifying its use.

Transarterial chemoembolisation in patients with hepatocellular carcinoma: low-dose doxorubicin reduces post-embolisation syndrome without affecting survival-prospective interventional study. Eur Radiol Exp 2021; 5:10. [PMID: 33649930 PMCID: PMC7921261 DOI: 10.1186/s41747-021-00204-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Accepted: 01/13/2021] [Indexed: 02/07/2023] Open
Abstract
Background No chemotherapeutic agents have been standardised for transarterial chemoembolisation (TACE). In particular, doxorubicin has no defined optimal dosage in TACE procedures. We compared low versus currently used dose of doxorubicin for TACE in patients with hepatocellular carcinoma (HCC) in terms of severity of post-embolisation syndrome (PES) and overall survival (OS). Methods From October 2014 to March 2018, we enrolled patients with primary HCC scheduled for TACE. Patients were randomised to receive 50 mg (group A) or 100 mg (group B) of doxorubicin. Outcomes were the rate of patients with PES; free-time-to-PES; changes in laboratory results; tumour response at 1, 3, and 6 months after TACE; and overall survival. Results Twenty-eight patients (24 males, 4 females) were enrolled, aged 58.9 ± 6.8 years (mean ± standard deviation). Fifteen of them palliated with 50 mg (group A) and 13 with 100 mg (group B) of doxorubicin for a total of 68 TACE procedures (of 28 patients who had repeated TACE procedures). Visual analogue scale (VAS) and duration of pain were significantly differently lower in group A than in group B (p < 0.001). The median duration of fever was shorter in group A than in group B (p = 0.003). No significant differences between both groups were observed for tumour response to TACE and OS. The doxorubicin dose was significantly correlated with duration of pain, fever, and VAS score. Conclusion A lower dose of doxorubicin (50 mg) was associated with fewer PES symptoms compared with 100 mg, without effects on tumour response nor OS.

Abstract
Background Hypoxia-inducible factor-1α (HIF-1α) has been selected as therapeutic gene in gene therapy. The aim of this study was to explore the treatment effect of combined transarterial embolization using microsphere treatment (MD) and intraarterial transfecting HIF-1α shRNA on hepatocellular carcinoma (HCC). Materials and Methods Rabbit skin fibroblast was transfected with HIF-1α shRNA to evaluate the knocking down efficiency. Sixteen rabbit VX2 liver tumor models were randomly divided into four groups: the control group without any treatment, the MD group, the shRNA group (HIF-1α shRNA transfection by transcatheter intraarterial infusion), and the shRNA+MD group. The necrotic score, mitotic count and expression of HIF-1α, vascular endothelial growth factor (VEGF), CD34 and periodic acid-Schiff (PAS) stain were evaluated at the 14th and 28th day after treatment. The expression of HIF-1α and VEGF of VX2 tumors was also evaluated by real-time polymerase chain reaction on the 28th day. Results The expression of HIF-1α-mRNA was lower in HIF-1α shRNA group than the control (p < 0.01). The tumor size was smaller in the shRNA + MD group than the shRNA group and the MD group (p < 0.05) on the 28th day. The growth rate of tumors in the shRNA + MD group was also lower than in other groups. The gene and protein expressions of both HIF-1α and VEGF in the shRNA + MD group were lower than the MD group, shRNA group and control group on the 28th day (p < 0.05). The necrotic score was higher in the shRNA + MD group than the MD group and control group (p < 0.05). The mitotic count and PAS-positive cells in shRNA + MD group were lower and CD34 was higher than the other three groups (p < 0.05). Conclusion Compared to therapy with MD or HIF-1α shRNA with transcatheter intraarterial transfection alone, the combined treatment has a better effect on HCC.

Abstract
Background/aims The dysregulation of circABCB10 may play an critical role in tumor progression. However, its function in liver cancer (HCC) is still unclear. Therefore, this experimental design is based on circABCB10 to explore the pathogenesis of HCC. Methods The expression of circABCB10 and miR-670-3p in HCC tissues was detected by RT-qPCR. CCK-8, Brdu incorporation, colony formation and transwell assays were used to determine the effect of circABCB10 on HCC cell proliferation and migration. Target gene prediction and screening, luciferase reporter assays were used to validate downstream target genes of circABCB10 and miR-670-3p. HMG20A expression was detected by RT-qPCR and Western blotting. The tumor changes in mice were detected by in nude mice. Results CircABCB10 was significantly increased in HCC tissues and cell lines, and high CircABCB10 expression was directly associated with low survival in HCC patients. Silencing of circABCB10 inhibited proliferation and invasion of hepatocellular carcinoma. In addition, circABCB10 acted as a sponge of miR-670-3p to upregulate HMG20A expression. In addition, overexpression of miR-670-3p or knockdown of HMG20A reversed the carcinogenic effects of circABCB10 in HCC. There was a negative correlation between the expression of circABCB10 and miR-670-3p, and a positive correlation between the expression of circABCB10 and HMG20A in HCC tissues. Conclusion circABCB10 promoted HCC progression by modulating the miR-670-3p/HMG20A axis, and circABCB10 may be a potential therapeutic target for HCC.

Abstract
PURPOSE To evaluate safety and efficacy of degradable starch microspheres (DSMs) TACE in a large clinical cohort of patients with unresectable HCC. MATERIALS AND METHODS This is a single-center consecutive patients cohort study. The study was approved by local institutional ethics committee. Written informed consent was obtained. From December 2013 to March 2018, 137 cirrhotic patients with unresectable HCC were enrolled. For DSMs-TACE, a mixture of 4 mL of DSMs, 6 mL of non-ionic contrast and doxorubicin at a dose of 50 mg/m2 were used. Primary end point was long-term outcome, in terms of time to progression (TTP) and overall survival (OS). Secondary endpoints were: safety, liver toxicity, 1-month percentage of tumor necrosis according to the modified RECIST criteria. RESULTS Two hundred and sixty-seven DSMs-TACE were performed in 137 HCC patients (33 patients in BCLC stage A, 84 patients in BCLC stage B, and 20 in stage C). Patients had a mean nodule number of 3.5 ± 1.2 (SD). Major complications were observed in 6.8% of cases. Post-embolization syndrome was common (101 patients 73.7%). According to mRecist criteria, a high objective response rate was obtained even after just one treatment (84.3% of patients showed complete response or partial response). The median TTP and OS after DSMs-TACE were 12 months and 36 months, respectively. OS at 6 months, 1 year, 2 and 3 years was 98%, 81.3%, 57.9%, 34.9%, respectively. CONCLUSION DSMs-TACE is a safe and effective therapy for patients with HCC, allowing to obtain a good rate of OS with excellent local tumor control.

Abstract
PURPOSE This pilot study was performed to investigate safety and local tumor control following transarterial embolization with small-size particles loaded with irinotecan (DEB-IRI) in patients with colorectal liver metastases (CRLM). MATERIALS AND METHODS Patients with pretreated CRLM with mono- or bilobar lesions involving less than 60% of the liver parenchyma and Eastern Cooperative Oncology Group performance status 0 or 1 underwent superselective DEB-IRI embolization with 40 µm diameter embolic microspheres. RESULTS Eighteen patients (11 males, 7 females, median age 61 years) underwent 80 embolization procedures (mean 4.4, range 2-12 per patient). No serious adverse events were reported within 30 days. A total of 39 treatment-related AEs occurred across all embolization procedures. No G4 or G5 treatment-related AEs occurred. Local tumor control, defined as complete response, partial response, or stable disease, was achieved in 16/18 (88.9%), 7/17 (41.2%), and 3/17 (17.6%) patients at 3, 6, and 12 months, respectively. Median liver progression-free survival was 5.9 months (range 27-409 days), and median overall survival was 13.5 months. CONCLUSION In this small series, DEB-IRI embolization with small beads was demonstrated a safe procedure in the treatment of patients with CRLM. The promising results in terms of liver-specific progression-free survival and overall survival reported deserve further confirmation in larger prospective trials. LEVEL OF EVIDENCE Level 4, case series.

Abstract
PURPOSE Dedicated tumor feeding vessel detection software (TFVDS) using cone beam CT has shown a higher sensitivity to detect tumor feeding vessels during hepatic arterial embolization (HAE) of hepatocellular carcinoma (HCC) compared to 2D imaging. Our primary hypothesis was that HCC tumors treated with HAE guided by a TFVDS would show more complete response (CR) than when treated with 2D imaging alone. Secondary analysis of the impact on X-ray exposure was performed. MATERIALS AND METHODS Nineteen males and 8 females (median age: 69 year, 46-85) with 44 tumors (median size: 38 mm, 6-100) treated with selective HAE between January 2013 and December 2014 were included. Exclusion criteria were: extra-hepatic supply, >4 tumors, tumor size >10 cm, and adjunctive local therapy. Baseline patient and procedure characteristics were reviewed. Differences in CR per modified Response Evaluation Criteria in Solid Tumors were assessed by univariate and multivariate analyses for tumor size, number, location, particles size, and use of TFVDS. RESULTS Median imaging follow-up was 20.1 months (2-33). Use of TFVDS (13 patients, 19 tumors) was the only factor predictive of CR (OR = 3.85 [CI95%: 1.09, 13.67], p = 0.04) on univariate analysis but not on multivariate analysis (OR = 3.26 [0.87, 12.23], p = 0.08). A higher rate of CR was observed for HAE using TFVDS guidance versus 2D imaging alone (68.4%, 13-19, vs. 36%, 9-25, p = 0.03). Median dose area product was lower when TFVDS was used (149.7 Gy.cm2, 38-365, vs. 227.8 Gy.cm2, 85.3-468.6, p = 0.05). CONCLUSIONS HCC embolized with TFVDS may result in improved local tumor response without increasing the dose exposure.

Abstract
Transarterial chemoembolisation (TACE) is well established in the treatment of primary hepatocellular carcinoma and of metastatic disease from colorectal and neuroendocrine tumours. There are few published studies on the effectiveness of treating hepatic metastases from medullary thyroid carcinoma with chemoembolisation and none to our knowledge utilising bland particle transarterial embolisation (TAE). Here we describe the management of multifocal hepatic metastases from medullary thyroid cancer in a 39-year-old woman who underwent bland particle TAE with a biochemical and radiological response and discuss the potential for a wider scope of clinical application for bland TAE in hepatic metastases.

[PMID: 28144395 PMCID: PMC5241526 DOI: 10.4251/wjgo.v9.i1.4] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2016] [Revised: 10/13/2016] [Accepted: 11/21/2016] [Indexed: 02/05/2023] Open
Abstract
Neuroendocrine (NE) gastroenteropancreatic tumors are a heterogeneous group of neoplasias arising from neuroendocrine cells of the embryological gut. Their incidence have increased significantly over the past 3 decades probably due to the improvements in imaging and diagnosis. The recent advances in molecular biology have translated into an expansion of therapeutic approaches to these patients. Somatostatin analogs, which initially were approved for control of hormonal syndromes, have recently been proven to inhibit tumor growth. Several new drugs such as antiangiogenics and others targeting mammalian target of rapamycin pathways have been approved to treat progressive pancreatic neuroendocrine tumors (NETs) although their role in non-pancreatic is still controversial. The treatment of NETs requires a coordinated multidisciplinary approach. The management of localized NETs primarily involves surgical resection followed by surveillance. However, the treatment of unresectable and/or metastatic disease may involve a combination of surgical resection, systemic therapy, and liver-directed therapies with the goal of alleviating symptoms of peptide release and controlling tumor growth. This article will review the current therapeutic strategies for metastatic gastroenteropancreatic NETs and will take a glimpse into the future approaches.
