Objective: The purpose of this study was to investigate the overall survival, efficacy, and safety of small (100-300 µm) versus large (300-500 and 500-700 µm) doxorubicin drug-eluting beads transarterial chemoembolization (DEB TACE) in patients with unresectable hepatocellular carcinoma (HCC)., Materials and Methods: Ninety-four consecutive patients with unresectable HCC who underwent 269 DEB TACE procedures in 48 months were studied. DEB TACE procedures were performed using different DEB sizes: 100-300 µm (Group A, 59 patients) and with mixed 300-500 and 500-700 µm DEB (Group B, 35 patients). Survival rates were compared between the groups., Results: The overall median survival in groups A and B were 15.1 and 11.1 months, respectively (p=0.005). Both groups were similar in demographics, tumor burden, and differential staging (p>0.5). Substratification of overall survival according to Child-Pugh class and Okuda, Cancer of the Liver Italian Program (CLIP), and Barcelona Clinic Liver Cancer (BCLC) staging were significantly higher in group A than in group B (p<0.05). Common terminology criteria for adverse events (CTCAE) grade III adverse events and 30-day mortality were significantly lower in group A than in group B (6.8% vs 20%; p=0.04, and 0% vs 14.3%; p=0.001, respectively). The particle size, Child-Pugh class, and serum α-fetoprotein level were significant prognostic indicators of survival on multivariate analysis., Conclusion: TACE with 100-300 µm sized DEB is associated with significantly higher survival rate and lower complications than TACE with 300-500 and 500-700 µm sized DEB.

Purpose: To investigate the safety and efficacy of transarterial chemoembolization using doxorubicin drug-eluting beads (DEBs) in patients with Barcelona Clinic Liver Cancer (BCLC) C stage hepatocellular carcinoma (HCC)., Methods: Consecutive patients with initial staging of BCLC C HCC who received DEB transarterial chemoembolization over the last 5 years were studied. The study included 121 patients (mean age, 61.2 years old). Adverse events (AEs) after DEB transarterial chemoembolization were studied in detail and were recorded as per the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.03 criteria. Survivals were analyzed according to parameters from the time of first DEB transarterial chemoembolization. Kaplan-Meier method by log-rank test and Cox proportional hazard model were used for survival analysis., Results: AEs occurred in 30.2% of patients. No AEs were greater than Common Terminology Criteria for Adverse Events grade III. Grade I and II AEs included nausea and vomiting in 7.8% of patients and abdominal pain in 23.8% of patients. Grade III AEs were noted in 1.06% of patients. There were no gastrointestinal or hepatic complications. There were no deaths within 30 days after DEB transarterial chemoembolization. The overall median survival was 13.5 months. Among the Child-Pugh class A patients, those without PVT and metastasis (28.9%) had better survival when treated with DEB transarterial chemoembolization than those with PVT and metastases (9.9%) (18.8 mo versus 4.4 mo, P = .001). Ascites, performance status, Okuda stage HCC, serum alpha fetoprotein levels, and etiologic factor for chronic liver disease predicted survival., Conclusions: DEB transarterial chemoembolization appears to be a safe and effective treatment option for patients with BCLC C HCC. Patients with Child-Pugh class A without PVT and metastasis benefited most from DEB transarterial chemoembolization., (Copyright © 2013 SIR. Published by Elsevier Inc. All rights reserved.)

Purpose: The aim of this study was to investigate the safety and feasibility of same-day discharge of patients with unresectable hepatocellular carcinoma (HCC) after doxorubicin drug-eluting bead (DEB) transarterial chemoembolization and to elucidate the factors predisposing to overnight admission., Materials and Methods: Consecutive patients with unresectable HCC who underwent superselective 100-300 μm DEB transarterial chemoembolization were included. The parameters of same-day therapy (group A) were compared with those of patients admitted overnight (group B). A χ2 test and a t test were used to compare categorical and continuous variables accordingly., Results: Seventy-six patients (mean, 61 y) received 110 DEB transarterial chemoembolization treatments over an 8-month study period. In 84.5% (93/110) of DEB transarterial chemoembolization procedures, the patients were discharged on the same day (group A). The causes of hospitalization included the worsening of comorbidities in 41.1% (7/17), pain control in 29.4% (5/17), and groin and closure device-related complications in 29.4% (5/17) of patients. The mean Charlson comorbidity scores in groups A and B were 6.96 (standard deviation [SD] ± 1.98) and 8.47 (SD ± 2.18) (P = .0005), respectively. All of the patients in group B had Barcelona Clinic Liver Cancer (BCLC) stages C and D HCC (P = .024). There were no Common Terminology Criteria for Adverse Events (CTCAE) grade III or worse adverse events (AEs). There was no mortality or emergency visits within 30 days of discharge., Conclusions: Same-day discharge after superselective DEB transarterial chemoembolization for unresectable HCC is safe and feasible. BCLC C or D stage of disease, a higher Charlson comorbidity score, and groin or closure device complications are correlated with a greater likelihood for overnight admission., (Copyright © 2012 SIR.

Background: Hepatocellular carcinoma (HCC) is a vascular tumor that proliferates through angiogenic pathways mediated, in part, by vascular endothelial growth factor receptor 2 (VEGFR2), and platelet-derived growth factor receptor (PDGFR) α and β. We hypothesized that overexpression of these proteins is associated with decreased survival after resection., Methods: A total of 57 patients, with available tissue for analysis, who underwent liver resection for HCC between August 2000 and March 2008 at a single institution were identified from a prospectively maintained database. Tumor specimens were assessed with immunohistochemistry for VEGFR2, PDGFR-α, and PDGFR-β expression and were graded by an experienced pathologist. Primary outcome was overall survival (OS)., Results: Median patient age was 64 years; 65% (n=37) were male. Median follow-up was 24.5 months, and median OS was 25.5 months. Median tumor size and number were 7 cm and 1, respectively. Macro and microvascular invasion was present in 9% (n=5) and 42% (n=24) of patients, respectively. Seventy-five percent of patients had tumors exceeding Milan criteria. 9% had positive resection margins. Thirty-five percent of patients had cirrhosis and the median nonadjusted Model for End-Stage Liver Disease (MELD) score was 7.5. Tumors exhibited differential expression of VEGFR2 (low: 79%, high: 21%), PDGFR-α (low: 93%, high: 7%), and PDGFR-β (low: 96%, high: 4%). After excluding all 30-day deaths (n=7), high PDGFR-α and PDGFR-β expression were independently associated with decreased OS (8.7 vs 29.1 months, P=0.01; 2.8 vs 28.8 months, P<0.001; respectively). High VEGFR2 expression displayed a trend toward decreased OS (20.8 vs 27.5 months, P=0.2). When adjusted for tumor burden, vascular invasion, margin status, and MELD score on independent multivariate analyses, both PDGFR-α and -β high expression were independently associated with decreased survival., Conclusions: High expression of PDGFR-α and PDGFR-β may be independently associated with decreased OS irrespective of margin status, MELD score, and tumor extent. This finding may help to select patients who would benefit from targeted inhibitor therapy in the adjuvant setting.

Purpose: To compare survival after treatment with either locoregional therapy (LRT) or supportive care in patients with hepatocellular carcinoma (HCC) within the Milan criteria., Materials and Methods: Patients with HCC who were classified within the Milan criteria (solitary HCC

Background and Objectives: Chemoembolization with doxorubicin drug eluting beads (DEB) is a novel locoregional treatment modality for unresectable hepatocellular carcinoma (HCC). Initial animal studies and clinical trials suggest that treatment with DEB may provide safer and more effective short-term outcomes than conventional chemoembolization. Current study explores long-term survival benefits., Methods: Consecutive patients who received transcatheter therapy with DEB or conventional chemoembolization as sole therapy between 1998 and 2008 were studied. Statistical analysis was performed using Kaplan-Meier estimator with log-rank testing, chi-squared, and independent t-tests., Results: Seventy-one patients were included in this study, 45 (63.4%) received therapy with DEB (group A) and 26 (36.6%) underwent conventional chemoembolization (group B). Median survival from diagnosis of HCC in groups A and B were 610 (351-868) and 284 days (4-563; P = 0.03), respectively. In Okuda stage I, survival in groups A and B were 501 (421-528) and 354 days (148-560, P = 0.02). In Child-Pugh classes A and B, survival in groups A and B were 641 (471-810) and 323 days (161-485, P = 0.002). Median survival in patients with Cancer of Liver Italian Program (CLIP) score

Background: Transarterial chemoembolization (TACE) with drug-eluting beads (DEB) is a new treatment modality. Little is known about prognostic factors affecting survival after DEB TACE for patients with hepatocellular carcinoma (HCC)., Methods: Patients who underwent TACE with doxorubicin DEB for unresectable HCC during 2006-2008 were studied. Survival was calculated from the day of first transcatheter therapy. Survival analysis was performed using Kaplan-Meier estimations. Survival curves were compared using the log-rank test., Results: Fifty patients underwent chemoembolization with doxorubicin DEB. They included 39 women and 11 men, with a median age of 57.5 years (range 28-91 years). Eighteen patients died during the study period and 32 remained alive. Overall survival rates at 6 months, 1 year and 2 years from the first administration of doxorubicin DEB TACE were 71%, 65% and 51%, respectively. Prognostic factors found to be significant on univariate analysis were Child-Pugh class, Okuda staging, bilirubin > 2 mg/dl, albumin < 3.0 g/dl, Model for End-stage Liver Disease (MELD) score, serum alphafetoprotein (AFP), Cancer of the Liver Italian Programme (CLIP) score, tumour satisfying Milan criteria, Eastern Cooperative Oncology Group (ECOG) performance status (PS) and Barcelona Clinic Liver Cancer (BCLC) staging., Conclusions: Child-Pugh class, Okuda staging, bilirubin > 2 mg/dl, albumin < 3 g/dl, MELD score, serum AFP, CLIP score, Milan criteria, ECOG PS and BCLC staging were found to be prognostic markers of survival after treatment with doxorubicin DEB TACE in patients with unresectable HCC.
