Dynamic changes of radiological and radiomics patterns based on MRI in viable hepatocellular carcinoma after transarterial chemoembolization.

This study aims to analyze the magnetic resonance imaging (MRI) change patterns of viable hepatocellular carcinomas (HCCs) following the initial transarterial chemoembolization (TACE). A retrospective analysis of HCC patients' initial TACE from February 2015 to October 2022 across three centers and a clinical trial (NCT03113955) was conducted. The viability of residual HCCs at one and six months after TACE was evaluated using the LI-RADS Treatment Response Algorithm (LR-TRA) v2024. The radiological and radiomics features of post-TACE viable tumors between baseline and one-month, and between one- and six- months were compared using Wilcoxon signed-rank test and McNemar's test. A total of 160 viable tumors were included in the study. Viable tumors at one month after TACE exhibited higher T1WI intensity (P =.024), lower T2WI intensity (P =.005), fewer washout features (P <.001), smaller size (P <.001), and higher ADC values (P <.001) compared to baseline HCC imaging.A significant reduction in DWI intensity (P =.002) and ADC values (P <.001) were observed in viable tumors at one month compared to those at six months. There were 82 (45.1%) radiomics features that changed significantly between the baseline and one-month. Only three radiomics features showed statistically significant difference of viable tumors between one- and six-month. Compared to the baseline, viable HCCs after TACE demonstrated significant changes of imaging characteristics in a series of radiological and radiomics features at one- and six-month follow-ups. Clinically diagnosing of viable HCCs using radiological methods is challenging. A comprehensive analysis of these imaging characteristics can facilitate the accurate identification of viable tumors.

Promising PD-1 antagonists for liver cancer: an evaluation of phase II and III results.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a significant cause of cancer-related morbidity and mortality. Limited treatment options for advanced stages emphasize the need for effective therapies. This review examines immune checkpoint inhibitors (ICIs), specifically PD-1, PD-L1, and CTLA-4 inhibitors, as novel treatments for advanced HCC. The review includes data from phase II and III clinical trials that evaluate ICI combinations with tyrosine kinase inhibitors (TKIs) and anti-angiogenic agents, as well as locoregional treatments such as Transarterial Chemoembolization (TACE). Clinical outcomes, including progression-free survival and overall response rates, were analyzed along with the incidence and management of immune-related adverse events (irAEs). A systematic literature review method was applied to ensure the inclusion of comprehensive, high-quality studies. ICI-based therapies and their combinations are reshaping the treatment landscape for advanced HCC by providing improved outcomes and potentially extending patient survival. Although promising, these therapies require further refinement to optimize sequencing and treatment selection, especially for patients with different levels of liver function and disease stages. Managing adverse effects effectively is essential for maximizing the benefits of these therapies in clinical practice. Continued research is needed to support the development of personalized approaches that can better tailor these treatments to individual patient needs, ultimately enhancing the overall effectiveness and safety of HCC management.

Transarterial Chemoembolization in Locally Advanced Rectal Cancer: A Systematic Review

Background: Locally advanced rectal cancer (LARC) presents a significant treatment challenge. Transarterial chemoembolization (TACE) has emerged as a potential adjunctive treatment, offering targeted delivery of chemotherapeutic agents to the tumor site, minimizing systemic exposure. This systematic review aims to assess the current literature on this novel technique and evaluate the safety and efficacy profile of TACE in treating this complex cohort of patients. Methods: A comprehensive literature search was conducted across multiple databases, including PubMed, EMBASE, and Cochrane Library, to identify studies evaluating TACE in LARC. Inclusion criteria encompassed clinical trials, cohort studies, and case series reporting on outcomes such as tumor response rate, overall survival (OS), progression-free survival (PFS), and treatment-related adverse events. Results: A total of eight studies involving 543 patients met the inclusion criteria. The studies varied in design, with five prospective and three retrospective studies. A higher prevalence of male participants (68.7%) was noted, with a median age of 60.3 years. The studies primarily evaluated the efficacy and safety of TACE in LARC treatment. Pathological response rates, tumor reduction, and survival outcomes varied across studies, with TACE showing promise in reducing tumor size, improving survival, and controlling metastasis. Major complications were rare, reported in 6.0% of cases. Conclusions: TACE is a promising therapeutic option for patients with LARC, demonstrating favorable tumor response rates and manageable toxicity profiles. Further large-scale, randomized controlled trials are warranted to confirm these findings and better define the role of TACE in the multimodal treatment of LARC.

Comparison of drug-eluting bead transarterial chemoembolization combined with apatinib versus drug-eluting bead transarterial chemoembolization for the treatment of unresectable hepatocellular carcinoma: a randomized, prospective, multicenter phase III trial.

This randomized, prospective, multicenter (12 centers in China) phase III trial (Chinese Clinical Trial Registry #ChiCTR2000041170) compared drug-eluting bead transarterial chemoembolization (DEB-TACE) combined with apatinib and DEB-TACE monotherapy for patients with unresectable hepatocellular carcinoma (uHCC). Progression-free survival (PFS) was the primary endpoint. Overall survival (OS), mRECIST-based objective response rates (ORR) and disease control rates (DCR), and treatment-related adverse events (TRAEs) were secondary endpoints. Totally 243 cases were randomized, with 122 and 121 in the DEB-TACE + apatinib and DEB-TACE groups, respectively. Cases administered DEB-TACE + apatinib displayed markedly improved median PFS (7.1 months [95%CI 6.6-8.3] vs. 5.2 months [95%CI 5.0-5.9]) and OS (23.3 months [95%CI 20.7-29.6] vs. 18.9 months [95%CI 17.9-20.1] compared with those treated with DEB-TACE (both p < 0.001). Additionally, patients administered DEB-TACE + apatinib had elevated ORR (56.6% vs. 38.8%) and DCR (89.3% vs. 80.2%) versus the DEB-TACE group (both p < 0.001). Majority of TRAEs were mild and manageable. Regarding DEB-TACE-related TRAEs, the rates of hepatic artery thinning and spasms were elevated during the second DEB-TACE in cases administered DEB-TACE + apatinib vs. DEB-TACE. The commonest apatinib-related TRAEs in the DEB-TACE + apatinib group included hypertension, hand-foot syndrome, fatigue, and diarrhea. In conclusion, DEB-TACE plus apatinib demonstrates superior PFS versus DEB-TACE monotherapy in uHCC cases, maintaining a favorable safety profile with similar occurrences of AEs.

An experimental study on the diagnostic advantage of dual-energy computed tomography over single-energy scan to evaluate the treatment effect following transcatheter arterial chemoembolization.

We assessed the diagnostic advantage of dual-energy computed tomography (DECT) over single-energy computed tomography (SECT) to evaluate lipiodol accumulation in target lesions following transcatheter arterial chemoembolization (TACE). TACE was performed in 10 rabbits in whom the VX2 tumor was implanted in their left liver lobes. The miriplatin-lipiodol mixture was injected into the common hepatic artery. All rabbits were sacrificed 2 days after TACE, and the liver was harvested. CT was performed using both single-energy and dual-energy scan modes. The specimen was stained with Oil Red O to evaluate lipiodol accumulation; this was considered the reference standard. Mutual information (MI) was used to evaluate the significance of radiological-pathological correlation. Estimated iodine content values on iodine material density images were compared with actual values obtained using mass spectroscopy. Mean MI values were 0.69, 0.32, 0.83, 0.72, 0.65, and 0.58 for single-energy scan; iodine density images; and virtual monoenergetic images for energy levels of 40, 60, 80, and 100 keV, respectively. The MI value of the monochromatic image (40 keV) was the highest among all sequences. However, this was not significant compared with the single-energy scan (p = 0.81). A significant correlation was observed between the estimated and actual values of iodine content (Pearson's product moment coefficient = 0.70, p = 0.023). More accurate and quantitative lipiodol evaluation in targeted tumors after TACE can be achieved by applying DECT rather than SECT.

Comparison of adjuvant treatment regimens for high-risk hepatocellular carcinoma: a Bayesian network meta analysis and systematic review

BackgroundThe five-year recurrence rate for patients with hepatocellular carcinoma (HCC) is as high as 70%. Patients with high-risk recurrence factors experience significantly poorer prognosis. Local regional therapies, including transarterial chemoembolisation (TACE), hepatic arterial infusion chemotherapy (HAIC), radiotherapy, and emerging immunotherapy, are commonly used adjuvant treatment options. We conducted an indirect comparison of these adjuvant therapies for such patients.MethodsWe conducted a systematic search in public databases for relevant studies and assessed the efficacy and safety of the corresponding therapies by consolidating disease-free survival (DFS), overall survival (OS), and adverse events (AEs).ResultsA total of eight randomised controlled trials were ultimately included. The Gelman-Rubin plot and kernel density estimation indicate that the stability of the combined model is satisfactory.Conclusionimmunotherapy is not inferior to local regional therapies in delaying tumour recurrence, however, the higher incidence of AEs remains a significant concern. Adjuvant radiotherapy demonstrated superior efficacy in delaying tumour recurrence compared to adjuvant TACE, although further support from phase III clinical trial evidence is required.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/, identifier CRD42024576316.

Clinical outcomes of modified transarterial chemoembolization vs. drug-eluting bead transarterial chemoembolization as initial treatment for single hepatocellular carcinoma: a propensity score matching analysis.

Optimizing transarterial chemoembolization (TACE) can enhance treatment efficacy for hepatocellular carcinoma (HCC). This study compares modified TACE (M-TACE), which combines a lipiodol-based emulsion and drug-eluting beads, with drug-eluting bead TACE (DEB-TACE) as initial therapies for solitary HCC. In this retrospective study, 185 patients undergoing M-TACE or DEB-TACE were evaluated. Propensity score matching was used to create 69 balanced pairs. Initial tumor response, repeated treatments within six months, local tumor progression (LTP), overall survival (OS), and adverse events (AEs) were assessed. M-TACE exhibited significantly higher initial complete response (CR) rates (39.1% vs. 23.2%, p = 0.043) and fewer repeated treatments within six months (1.7 ± 0.9 vs. 2.1 ± 0.7; p = 0.033) compared to DEB-TACE. LTP rates were notably lower with M-TACE at 12 months (39.1% vs. 65.2%, p = 0.002), and median time to LTP was prolonged with M-TACE (13.3 vs. 8.2 months, p = 0.038). Stratified analysis revealed a significantly longer OS in individuals achieving a CR after the initial M-TACE (50.5 vs. 33.4 months, p = 0.043). However, the overall study population did not exhibit a significant difference in OS between the two groups. Comparable AEs (all p > 0.05) were observed. M-TACE showed higher initial CR rates, lower LTP rates, and extended time to LTP compared to DEB-TACE, indicating its potential to enhance TACE effectiveness for solitary HCC.

Efficacy, safety, and biomarker analysis of TACE combined with lenvatinib plus sintilimab in unresectable hepatocellular carcinoma: a real-world study

BackgroundThe integration of transarterial chemoembolization (TACE) with systemic therapy has demonstrated improved survival outcomes in patients with unresectable hepatocellular carcinoma (HCC). However, there is limited evidence evaluating the combination of TACE with the systemic regimen of anti-PD-1/L1 inhibitor plus lenvatinib. This study aims to assess the efficacy and safety of TACE combined with lenvatinib and sintilimab in unresectable HCC patients.MethodsUnresectable HCC patients who received TACE in combination with sintilimab plus Lenvatinib as first-line treatment from 1 January 2020 to 31 March 2023 were included for the analysis. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and disease control rate (DCR) were evaluated by modified Response Evaluation Criteria in Solid Tumors criteria. Exploratory biomarker analysis was conducted.ResultsThe study included 70 patients with unresectable HCC, predominantly male and infected with Hepatitis B. The median follow-up duration for the whole cohort was 13.8 months (95% CI 11.08–16.7). The ORR was 61.4% (95% CI, 49.0%–72.8%) and the DCR was 68.6% (95%CI, 56.4%–79.2%). The median PFS was 13.2 months (95% CI 11.0-NA), with a corresponding 1-year PFS rate of 50.3% (95% CI 39.7%-65.5%). The median OS was not reached, and the 1-year OS rate was 89.3% (95% CI 81.4%–97.9%). The most common treatment-related adverse events (TRAEs) were fatigue 38.6% (27/70), hypertension 32.9% (23/70), and hand-foot syndrome 31.4% (22/70). Most TRAEs were mild-to-moderate and manageable. In addition, significant predictive value was found in alpha-fetoprotein levels (AFP), with patients showing a level of decrease post-treatment having better PFS.ConclusionThe combination regimen demonstrated promising efficacy in treating unresectable HCC, accompanied by manageable safety profiles. Furthermore, the results of this investigation suggest that AFP holds promise as predictive biomarkers for this treatment strategy.

088. Transarterial Chemoembolization for Head and Neck Cancer: Case Series

Background: Head and neck cancers represent a diverse group of malignancies arising from the complex anatomy of the oral cavity, pharynx, larynx, nasal cavity, paranasal sinuses, and salivary glands. While traditional treatments like surgery, radiation, and chemotherapy remain mainstays, transarterial chemoembolization (TACE) has emerged as a potential therapeutic option, particularly for advanced or recurrent cases. We present two cases of head and neck cancer that receive TACE. Case: First Case: A 46 years old woman, with big lump on her left cheek. The patient was diagnosed with Basal Cell Adenocarcinoma T3N0M0 at right submandibular region. He has history of Docetaxel and Carboplatin 6 cycles chemotherapy. Second Case: A 51 years old man, complain a lump on his right tongue. The patient was diagnosed with Squamous Cell Carcinoma Well Differentiated at left glossus region. But no history of chemotherapy. Conclusion: Two cases with head and neck cancer in our center has good clinical outcome after receiving chemotherapy through TACE procedure. TACE is offering a targeted approach to deliver chemotherapy and induce tumor necrosis. Although, TACE is commonly used for liver cancer, but it demonstrates promising potential in improving outcomes for head and neck cancer patients in the future.

089. TACE for Residive Malignant Peripheral Nerve Sheath Tumor and Leiomyosarcoma: Case Series

Background: Malignant peripheral nerve sheath tumors (MPNST) are malignant, locally aggressive soft tissue sarcomas (STS) of the peripheral nerve or nerve sheath cells. Leiomyosarcomas are malignant tumors originating from the smooth muscle. Transarterial chemoembolization (TACE) is an interventional treatment to deliver chemoembolic materials. Case: First case is a 50-year-old male visited Oncology Surgery Polyclinic due to the presence of a tumor on his left forearm that was progressively increasing in size during the past two months. The MRI was done, the diagnosis of a residive malignant peripheral nerve sheath tumor was made. Second case is a 40-year-old female visited the Oncology Surgery Polyclinic due to the presence of a tumor on her right breast that was progressively increasing in size and the diagnosis of a Leiomyosarcoma at the right breast was made. Transarterial chemoembolization (TACE) was performed to both of the cases. Conclusion: MPNST and Leiomyosarcoma are malignant tumor that can be treated with doxorubicin chemotherapy through the TACE procedure.

Left radial vs right femoral: comparison between arterial accesses in c-TACE procedures in terms of operator radiations exposure and patient comfort.

This multicenter prospective study aims to compare transradial access versus transfemoral access in conventional transarterial chemoembolization (c-TACE) procedures, focusing on operators radiations exposure, patients comfort, technical success and vascular access complications. Patients were affected by hepatocellularcarcinoma (HCC) in intermediate stage or previous stages unfit for ablation and/or surgery; they were randomized into two groups according to arterial access site (Group F: right femoral access in standard position; Group R: radial access with left arm abduced 90°). Overall fluoroscopy time was recorded. Eight thermoluminescence dosimeters were positioned immediately before each procedure to monitor radiation doses. Technical success was intended as complete HCC nodules lipiodolization at final plain cone-beam CT. Group F included 23 patients, while group R 19. Mean fluoroscopy time was lower in group F but difference was not statistically significant (p-value > 0.05). In terms of operators radiations exposure, no significant differences were found (p-value > 0.05). Technical success was obtained in 81.5% in group F and 84.8% in group R, without significant differences (p-value > 0.05). Patients discomfort was significantly (p-value < 0.05) higher in group F. Concerning minor complications, no statistical differences were appreciated (p-value > 0.05); no major complications occurred. In this study, no statistical differences were observed in terms of operators radiations exposure, fluoroscopy time and technical success during c-TACE performed with left radial access compared to right femoral access; patients comfort was significantly better with radial access. These data should lead interventional radiologists to favor radial access in c-TACE interventions.

Effectiveness of Steerable Microcatheters During Transarterial Chemoembolization for Hepatocellular Carcinoma.

Although transarterial chemo-embolization (TACE) is a key treatment for hepatocellular carcinoma (HCC), its effectiveness depends on the cannulation of the microcatheter tip into the feeding artery. Steerable microcatheters allow remote operation of the tip, enabling its insertion into feeding arteries otherwise difficult to reach. This study investigated the indications and effectiveness of steerable microcatheters in TACE for HCC. We retrospectively examined 22 patients with HCC who underwent TACE using steerable microcatheters at our Department between December 2014 and July 2024. Previous TACE administration, number of TACE sessions, and feeding artery disruption affecting TACE were examined. Among the first TACE cases requiring steerable catheters, three demonstrated steep bifurcation of the celiac artery or superior mesenteric artery from the parent artery, two had sharp bends in the posterior segment, and four had the left hepatic artery bifurcating from the left gastric artery. All three procedures performed in the inferior phrenic artery required second TACE sessions. Steerable microcatheters were used in two patients during their eighth TACE session; both procedures involved selective cannulation of neovessels feeding from a new anastomotic branch to segment 4, following damage to the main feeding artery from repeated treatments. Steerable microcatheters were effective in reaching steep or strongly bending branches of the parent or feeding artery in the first TACE cases or neovessels and anastomotic branches in previous TACE cases. Studies with larger sample sizes are warranted to validate the use of steerable microcatheters for effective TACE.

Development and validation of a model for predicting who can benefit from multiple TACE in HCC patients

This study was to develop and validate a model for predicting who can benefit from multiple transcatheter arterial chemoembolization (TACE) in hepatocellular carcinoma (HCC) patients.228 and 98 patients were included in the development and validation sets, respectively. The primary clinical endpoint was benefiting from consecutive multiple TACE treatments. Logistic regression analysis was used to screen the independent risk factors for the clinical endpoint. The independent risk factors were then used to construct the predictive model. The area under receiver operating characteristic (ROC) curves, calibration curves, and clinical decision curves were used to evaluate the predictive ability of the model.Multivariate Logistic regression analysis showed that complete envelope, hepatic lopes, tumor number, and alpha-fetoprotein (AFP) were independent risk factors for benefiting from multiple TACE in HCC patients. The area under the curve (AUC) of the model constructed by using independent risk factors in the development and validation sets was 0.843 (95% confidence interval [CI]: 0.784–0.902) and 0.828 (95%CI: 0.739–0.916), respectively. The calibration curves and clinical decision curves showed that the model had good predictive ability.The model established in this study has a good predictive effect on HCC patients who can benefit from multiple TACE.

Comparison of stereotactic body radiotherapy and transcatheter arterial chemoembolization for hepatocellular carcinoma: Systematic review and meta‐analysis

Stereotactic body radiation therapy (SBRT) is an emerging treatment for hepatocellular carcinoma (HCC), which provides excellent local control (LC) and prolongs overall survival (OS). However, in current guidelines, transcatheter arterial chemoembolization (TACE) has been proposed as a key treatment option for patients with early- and intermediate-stage HCC, whereas SBRT is not. Therefore, we performed a systematic review and meta-analysis of randomized controlled trials and retrospective studies using the propensity score (PS) to compare the outcomes of SBRT and TACE for HCC in a balanced manner. We systematically searched the PubMed, Cochrane, EMBASE, and Web of Science databases to identify randomized controlled trials and studies comparing SBRT and TACE using PS analysis. The hazard ratios (HRs) for OS and LC were pooled. The heterogeneity between the data collected from these studies was also assessed. SBRT led to a comparable OS (HR: 0.83; 95 % confidence interval (CI): 0.52–1.34; p = 0.44) to TACE, and significantly improved LC (HR: 0.25; 95 % CI: 0.09–0.67; p = 0.006). Considerable heterogeneity was observed in the HR of OS and LC. Although there was no significant difference in the rate of grade 3 or higher toxicities between TACE and SBRT, or between studies, liver toxicity was identified as a common adverse event associated with both SBRT and TACE. Compared to TACE, SBRT showed a comparable OS and improved LC without serious toxicity. Therefore, SBRT should be considered an effective treatment option for various stages of HCC, depending on the tumor factors and pretreatment liver function.

Gelation embolism agents suppress clinical TACE-incited pro-metastatic microenvironment against hepatocellular carcinoma progression

Current embolic agents in transcatheter arterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) encounter instability and easy leakage, discounting TACE efficacy with residual HCC. Moreover, clinical TACE aggravates hypoxia and pro-metastatic microenvironments, rendering patients with HCC poor prognosis. Herein, we developed Zein-based embolic agents that harness water-insoluble but ethanol-soluble Zein to encompass doxorubicin (DOX)-loaded mesoporous hollow MnO2 (HMnO2). The conditions and capacity of HMnO2 to generate reactive oxygen species (ROS) were assayed. Mechanical examinations of Zein-HMnO2@DOX were performed to evaluate its potential as the embolic agent. Invitro experiments were carried out to evaluate the effect of Zein-HMnO2@DOX on HCC. The subcutaneous HCC mouse model and rabbit VX2 HCC model were established to investigate its anti-tumor and anti-metastasis efficacy and explore its potential anti-tumor mechanism. The high adhesion and crosslinking of Zein with HMnO2@DOX impart Zein-HMnO2@DOX with strong mechanical strength to resist deformation and wash-off. Zein gelation and HMnO2 decomposition in response to water and acidic tumor microenvironment, respectively, enable continuous DOX release and Fenton-like reaction for reactive oxygen species (ROS) production and O2 release to execute ROS-enhanced TACE. Consequently, Zein-based embolic agents outperform clinically-used lipiodol to significantly inhibit orthotopic HCC growth. More significantly, O2 release down-regulates hypoxia inducible factor (HIF-1α), vascular endothelial growth factor (VEGF) and glucose transporter protein 1 (GLUT1), which thereby re-programmes TACE-aggravated hypoxic and pro-metastatic microenvironments to repress HCC metastasis towards lung. Mechanistic explorations uncover that such Zein-based TACE agents disrupt oxidative stress, angiogenesis and glycometabolism pathways to inhibit HCC progression. This innovative work not only provides a new TACE agent for HCC, but also establishes a new strategy to ameliorate TACE-aggravated hypoxia and metastasis motivation against clinically-common HCC metastasis after TACE operation.

Transarterial chemoembolization combined with molecular targeted agents plus immune checkpoint inhibitors for unresectable hepatocellular carcinoma beyond the up-to-seven criteria: a propensity score-matching analysis

Purpose Not all patients benefit from transarterial chemoembolization (TACE) due to the heterogeneity of the tumour burden in intermediate-stage hepatocellular carcinoma (HCC). To compare the outcomes of transarterial chemoembolization (TACE) combined with molecular-targeted agents plus immune checkpoint inhibitors (TACE-MTAs-ICIs) with those of TACE for patients with unresectable hepatocellular carcinoma (uHCC) that were beyond the up-to-seven criteria. Patients and methods Between January 2019 and July 2022, 130 patients diagnosed with uHCC beyond the up-to-seven criteria were retrospectively identified, including 47 patients who received TACE-MTAs-ICIs and 83 patients who received TACE alone. The primary endpoints were overall survival (OS) and progression-free survival (PFS); the secondary endpoints included tumour response and adverse events (AEs). Results There were 43 matched patients. The median OS and PFS times in the TACE-MTAs-ICIs group were significantly longer than those in the TACE group (OS: 27.2 vs. 15.9 months, p = 0.007; PFS: 15.4 months vs. 4.8 months, p < 0.001). The objective response rate (ORR) in the TACE-MTAs-ICIs group was higher than that in the TACE group (65.1% vs. 37.2%, p = 0.010). Reversible AEs (grade 3 or 4) occurred differently in TACE-MTAs-ICIs and TACE groups (83.7% vs. 51.2%, p = 0.001). Univariate and multivariate analyses revealed that TACE-MTAs-ICIs treatment was an independent favourable prognostic factor for both PFS and OS (p < 0.001). Conclusion For uHCC patients beyond the up-to-seven criteria, TACE-MTAs-ICIs provided superior ORR and OS. Early combined TACE and systemic treatment should shift for patients who are beyond these criteria.

Predictors of Immediate Deterioration of the Child-Pugh Classification From A to B After Transcatheter Arterial Chemo-Embolization for Treatment-Naive Hepatocellular Carcinoma.

The purpose of this study was to evaluate the predictors of deterioration of the Child-Pugh classification 1 month after transcatheter arterial chemo-embolization (TACE) in patients with treatment-naive hepatocellular carcinoma (HCC). Between 2010 and 2020, consecutive patients who underwent conventional TACE using epirubicin as the initial treatment were enrolled. Patients with Barcelona Clinic Liver Cancer stage-0, A or B and Child-Pugh class A were included. The Child-Pugh score was evaluated before treatment and 1 month after TACE. The following variables were analyzed by univariate and multivariate analyses as predictors of deterioration of the Child-Pugh class from A to B: age, sex, etiology, serum albumin, bilirubin, prothrombin time (PT), encephalopathy, ascites, largest tumor diameter, tumor number, tumor location, α-fetoprotein, protein induced by vitamin K absence or antagonist-II, epirubicin dosage, ethiodized oil dosage, and number of treated liver segments. A total of 152 patients were retrospectively enrolled. The deterioration rate of the Child-Pugh class from A to B was 8.6%. Multivariable analysis showed that serum albumin ≤ 3.8 g/dL, PT ≤ 80%, and largest tumor diameter ≥ 3.8 cm were predictors of deterioration of the Child-Pugh class. The deterioration rate to Child-Pugh class B was 0% in patients with up to one of these factors, 14.3% in those with two factors, and 70% in those with three factors. A combination of serum albumin ≤ 3.8 g/dL, PT ≤ 80%, and largest tumor diameter ≥ 3.8 cm can predict the immediate deterioration of the Child-Pugh classification from A to B following TACE.
