Purpose: The study was done to investigate whether positioning relieves the back pain and enhances comfort during bed rest after transhepatic arterial chemoembolization(TACE). Methods: A quasi-experimental design with non-equivalent control group non-synchronized design was used. The experimental group was placed semi Fowler's position for the first 2 hours. The following 4 hours the position was rotated hourly between 30 degrees laterally inclined position and a semi Fowler's position. The control group was maintained in a supine position for the 6 hours. Data were analyzed using t-test, $x^2$-test, Fisher's exact test and repeated measures ANOVA. Results: 1) Back pain intensity significantly decreased in the experimental group compared to the control group. 2) Comfort level significantly decreased in both groups, but there was no significant difference between the two groups. 3) There were no hematoma and bleeding complication in either group. In addition, there was no significant difference in urinary retention between the two groups. 4) Analgesics were less frequently taken by the experimental group. Conclusion: These results suggest that positioning relieves back pain without causing an increased incidence of hematoma and bleeding formation after TACE and this nursing intervention might help patients be more comfortable during the treatment of TACE.

Backgrounds/Aims: The efficacy of neoadjuvant transarterial chemoembolization (N-TACE) in resectable hepatocellular carcinoma (HCC) remains open to debate. While N-TACE may reduce tumor size, its impact on long-term outcomes is inconclusive. Methods: This meta-analysis reviewed studies on N-TACE before surgical resection vs. liver resection (LR) single large hepatocellular carcinoma (SLHCC) up to March 2023 from four online databases. Results: Five studies with 1,556 patients were analyzed. No significant differences between N-TACE and LR groups were observed in 1-, 3-, or 5-year overall survival (OS) and disease-free survival (DFS). No significant differences were noted in intraoperative blood loss between groups. Subgroup analysis showed favorable 1-, 3-, and 5-year OS with combination chemotherapy N-TACE (combination group), and better 1-year OS in the LR group with single-agent chemotherapy N-TACE (single-agent group). Five-year DFS favored LR in the single-agent group, and N-TACE in the combination group. Conclusions: Managing SLHCC requires intricate considerations, and the treatment strategies for this challenging subgroup of HCC need to be improved. The influence of N-TACE on long-term survival depends on the specific chemotherapy regimen employed, and its impact on intraoperative blood loss in SLHCC appears limited.

Purpose: To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) followed by radiotherapy (RT) in treatment-na$\ddot{i}$ve patients with locally advanced hepatocellular carcinoma (HCC). Materials and Methods: Eligibility criteria were as follows: newly diagnosed with HCC, the Barcelona Clinic Liver Cancer stage C, Child-Pugh class A or B, and no prior treatment for HCC. Patients with extrahepatic spread were excluded. A total of 59 patients were retrospectively enrolled. All patients were treated with TACE followed by RT. The time interval between TACE and RT was 2 weeks as per protocol. A median RT dose was 47.25 $Gy_{10}$ as the biologically effective dose using the ${\alpha}/{\beta}$ = 10 (range, 39 to 65.25 $Gy_{10}$). Results: At 1 month, complete response was obtained in 3 patients (5%), partial response in 27 patients (46%), stable disease in 13 patients (22%), and progressive disease in 16 patients (27%). The actuarial one- and two-year OS rates were 60.1% and 47.2%, respectively. The median OS was 17 months (95% confidence interval, 5.6 to 28.4 months). The median time to progression was 4 months (range, 1 to 35 months). Grade 3 or greater liver enzyme elevation occurred in only two patients (3%) after RT. Grade 3 gastroduodenal toxicity developed in two patients (3%). Conclusion: The combination treatment of TACE followed by RT with two-week interval was safe and it showed favorable outcomes in treatment-na$\ddot{i}$ve patients with locally advanced HCC. A prospective randomized trial is needed to validate these results.

Background and Aims: Hepatitis B virus (HBV) reactivation was reported to be induced by transcatheter arterial chemoembolization (TACE) in HBV-related hepatocellular carcinonma (HCC) patients with a high incidence. The effective strategy to reduce hepatitis flares due to HBV reactivation in this specific group of patients was limited to lamivudine. This retrospective study was aimed to investigate the efficacy of prophylactic entecavir in HCC patients receiving TACE. Methods: A consecutive series of 191 HBV-related HCC patients receiving TACE were analyzed including 44 patients received prophylactic entecavir. Virologic events, defined as an increase in serum HBV DNA level to more than 1 log10 copies/ml higher than nadir the level, and hepatitis flares due to HBV reactivation were the main endpoints. Results: Patients with or without prophylactic were similar in host factors and the majorities of characteristics regarding to tumor factors, HBV status, liver function and LMR. Notably, cycles of TACE were parallel between the groups. Ten (22.7%) patients receiving prophylactic entecavir reached virologic response. The patients receiving prophylactic entecavir presented significantly reduced virologic events (6.8% vs 54.4%, p=0.000) and hepatitis flares due to HBV reactivation (0.0% vs 11.6%, p=0.039) compared with patients without prophylaxis. Kaplan-Meier analysis illustrated that the patients in the entecavir group presented significantly improved virologic events free survival (p=0.000) and hepatitis flare free survival (p=0.017). Female and Eastern Cooperative Oncology Group (ECOG) performance status 2 was the only significant predictors for virological events in patients without prophylactic antiviral. Rescue antiviral therapy did not reduce the incidence of hepatitis flares due to HBV reactivation. Conclusion: Prophylactic entecavir presented promising efficacy in HBV-related cancer patients receiving TACE. Lower performance status and female gender might be the predictors for HBV reactivation in these patients.

Objective: To investigate the safety and efficacy of transcatheter arterial chemoembolization (TACE), combined with portal vein embolization (PVE), and high intensity focused ultrasound (HIFU) sequential therapy in treating patients with hepatocellular carcinoma (HCC). Methods: Patients with inoperative HCC were treated by two methods: in the study group with TACE first, then PVE a week later, and then TACE+PVE every two months as a cycle, after 2~3 cycles finally HIFU was given; in the control group only TACE+PVE was given. Response (CR+PR), and disease control rate (CR+PR+SD), side effects, overall survival and time to progress were calculated. Results: Main side effects of both groups were nausea and vomiting. No treatment related death occurred. In the study group, 32 patients received TACE for overall 67 times, PVE 64 times, and HIFU 99 times; on average 2.1, 2 and 3.1 times for each patient, respectively. In the control group, 36 patients were given TACE 78 times and PVE 74 times, averaging 2.2 and 2.1 times per patient. Effective rate: 25.0% in study group and 8.3% in control group (p>0.05). Disease control rates were 71.9% and 44.4%, respectively (p<0.05). In patients with portal vein tumor thrombus, the rate reduced over 1/2 after treatment was 69.2%(9/13) in the study and 21.4%(3/14) in the control group (p<0.05). Rate of AFP reversion or decrease over 1/2 was 66.7%(16/24) in study and 37%(10/27) (p<0.05) in control group. Median survival time: 16 months in study and 10 months in control group. PFS was 7months in study and 3 months in control group. Log-rank test suggested that statistically significant difference exists between two groups (p=0.024). 1-, 2- and 3-year survival rates were 56.3%, 18.8% and 9.3% in study, while 30.6%, 5.6% and 0 in control group, respectively, with statistically significant difference between two groups (by Log-rank, p = 0.014). Conclusions: The treatment of TACE+PVE+HIFU sequential therapy for HCC increases response rate, prolong survival, and could thus be a safe and effective treatment for advanced cases.

Background: Nausea and vomiting after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) are common in clinical practice, but few studies have reported the incidence and risk factors of such events. Objective: The purpose of this study was to analyze the incidence and risk factors of nausea and vomiting after TACE for HCC. Methods: This study was a single-center retrospective analysis of a prospectively maintained database. Between May 2010 and October 2012, 150 patients with HCC were analyzed for incidence and preprocedural risk factors. Results: The incidence of postembolization nausea and vomiting was 38.8% and 20.9%, respectively, in patients with HCC. Patients who developed nausea had lower levels (<100 IU/L) of serum alkaline phosphatase (ALP) compared to those without nausea ($123.04{\pm}69.38$ vs. $167.41{\pm}138.95$, respectively, p=0.044). Female gender correlated to a higher incidence of nausea as well (p=0.024). Patients who developed vomiting, compared to those who did not, also had lower levels (<100 IU/L) of serum ALP ($112.52{\pm}62.63$ vs. $160.10{\pm}127.80$, respectively, p=0.010), and serum alanine transferase (ALT) ($35.61{\pm}22.87$ vs. $4.97{\pm}29.62$, respectively, p=0.045). There were no statistical significances in the incidences of nausea and vomiting between male patients over 50 years old and female patients who have entered menopause (p=0.051 and p=0.409, respectively). Multivariate analysis by logistic regression analysis demonstrated that female gender and ALP>100 IU/L were the most independent predictive factors of postembolization nausea (odds ratio (OR): 3.271, 95% CI: 1.176-9.103, p=0.023 and OR: 0.447, 95% CI: 0.216-0.927, p=0.030, respectively). ALP>100 IU/L was also the most independent predictive risk factor of postembolization vomiting (OR: 0.389, 95% CI: 0.159-0.952, p=0.039). Conclusions: Postembolizaiton nausea and vomiting are common in patients with HCC. Recognition of the risk factors presented above before TACE is important for early detection and proper management of postembolization nausea and vomiting. Nevertheless, future studies are required.

Background: The aim of our present study was to compare quality of life (QoL) between intermediate-stage (BCLC-B) HCC patients who had undergone either liver resection or transcatheter arterial chemoembolization (TACE). Materials and Methods: A total of 102 intermediate-stage HCC patients participated in our study, including 58 who had undergone liver resection and 44 who had undergone TACE. Baseline demographic characteristics, tumor characteristics, and long-term outcomes, such as tumor recurrence, were compared and analyzed. QoL was assessed using the Short Form (SF)-36 health survey questionnaire with the mental and physical component scales (SF-36 MCS and PCS). This questionnaire was filled out at HCC diagnosis and 1, 3, 6, 12, 24 months after surgery. Results: For the preoperative QoL evaluation, the 8 domains related to QoL were comparable between the two groups. The PCS and MCS scores were significantly decreased in both the TACE and resection groups at1 month after surgery, and this decrease was greater in the resection group. These scores were significantly lower in the resection group compared with the TACE group (P<0.05). However, these differences disappeared at 3 and 6 months following surgery. One year after surgery, the resection group showed much higher PCS scores than the TACE patients (P=0.018), and at 2 years after surgery, the PCS and MCS scores for the resection group were significantly higher than those for the TACE group (P<0.05). Eleven patients (19.0%) in the resection group and 17 (38.6%) in the TACE group suffered HCC recurrence (P<0.05). Univariate and multivariate analyses indicated that tumor recurrence (HR=1.211, 95%CI: 1.086-1.415, P=0.012) was a significant risk factor for poorpostoperative QoL in the HCC patients.Conclusions: Due to its effects on reducing HCC recurrence and improving long-term QoL, liver resection should be the first choice for the treatment of patients with intermediate-stage HCC.

Objective: Clinical outcomes of patients who undergo transarterial chemoembolization (TACE) for single small hepatocellular carcinoma (HCC) are not consistent, and may differ based on certain imaging findings. This retrospective study was aimed at determining the efficacy of pre-TACE CT or MR imaging findings in predicting survival outcomes in patients with small HCC upon being treated with TACE. Besides, the study proposed to build a risk prediction model for these patients. Materials and Methods: Altogether, 750 patients with functionally good hepatic reserve who received TACE as the first-line treatment for single small HCC between 2004 and 2014 were included in the study. These patients were randomly assigned into training (n = 525) and validation (n = 225) sets. Results: According to the results of a multivariable Cox analysis, three pre-TACE imaging findings (tumor margin, tumor location, enhancement pattern) and two clinical factors (age, serum albumin level) were selected and scored to create predictive models for overall, local tumor progression (LTP)-free, and progression-free survival in the training set. The median overall survival time in the validation set were 137.5 months, 76.1 months, and 44.0 months for low-, intermediate-, and high-risk groups, respectively (p < 0.001). Time-dependent receiver operating characteristic curves of the predictive models for overall, LTP-free, and progression-free survival applied to the validation cohort showed acceptable areas under the curve values (0.734, 0.802, and 0.775 for overall survival; 0.738, 0.789, and 0.791 for LTP-free survival; and 0.671, 0.733, and 0.694 for progression-free survival at 3, 5, and 10 years, respectively). Conclusion: Pre-TACE CT or MR imaging findings could predict survival outcomes in patients with small HCC upon treatment with TACE. Our predictive models including three imaging predictors could be helpful in prognostication, identification, and selection of suitable candidates for TACE in patients with single small HCC.

Objective: To evaluate the outcomes of drug-eluting bead transarterial chemoembolization (DEB-TACE) according to the size of the beads for the treatment of small hepatocellular carcinoma (HCC). Materials and Methods: This retrospective study included 212 patients with a single HCC ≤5 cm from five tertiary institutions. One hundred and nine patients were treated with 70-150-㎛ doxorubicin DEBs (group A), and 103 patients received 100-300-㎛ doxorubicin DEBs (group B). The initial tumor response (assessed between 3 weeks and 2 months after DEB-TACE), time to local tumor progression (TTLTP), restricted mean duration of complete response (RMDCR), rate of complications, incidence of post-embolization syndrome, and length of hospital stay were compared between the two groups. Logistic regression was used to analyze prognostic factors for initial tumor response. Results: The initial objective response rates were 91.7% (100/109) and 84.5% (87/103) for groups A and B, respectively (P = 0.101). In the subgroup analysis of tumors ≤3 cm, the initial objective response rates were 94.6% (53/56) and 78.0% (39/50) for groups A and B, respectively (P = 0.012). There was no significant difference in the TTLTP (median, 23.7 months for group A vs. 19.0 months for group B; P = 0.278 [log-rank], 0.190 [multivariable Cox regression]) or RMDCR at 24 months (11.4 months vs. 8.5 months, respectively; P = 0.088). In the subgroup analysis of tumors >3-cm, the RMDCR at 24 months was significantly longer in group A than in group B (11.8 months vs. 5.7 months, P = 0.024). The incidence of mild bile duct dilatation after DEB-TACE was significantly higher in group B than in group A (5.5% [6/109] vs. 18.4% [19/103], P = 0.003). Conclusion: DEB-TACE using 70-150-㎛ microspheres demonstrated a higher initial objective response rate in ≤3-cm HCCs and a longer RMDCR at 24 months in 3.1-5-cm HCCs compared to larger DEBs (100-300-㎛).

Objective: This study evaluated the safety and objective response of combining $^{131}I$-labeled-metuximab (Licartin) with transarterial chemoembolization (TACE) in the treatment of unresectable hepatocellular carcinoma (HCC). Materials and Methods: In a multicenter open-label clinical trial, 341 enrolled patients with stage III/IV HCC according to TNM criteria were nonrandomly assigned to a trial group (n=167) and a control group (n=174), undergoing TACE following hepatic intra-arterial injection of licartin or TACE alone from July 2007 to July 2009. Radiopharmaceutical distribution was evaluated. The primary endpoint was overall survival; secondary endpoints included time-to-progression (TTP), toxicity and adverse events (AEs). Results: The radiobiological distribution demonstrated better localization of licartin in liver tumors than other tissues (P<0.01). The organ absorbed doses to liver and red marrow were $3.19{\pm}1.01Gy$ and $0.55{\pm}0.22Gy$, respectively. The 1-year survival rate was significantly higher [79.47% vs. 65.59%, hazard ratio (HR), 0.598, P=0.041] and TTP significantly improved ($6.82{\pm}1.28$ vs. $4.7{\pm}1.14months$, P=0.037) compared with the control group. Patients at stage III achieved more benefit of one year survival than stage IV in the trial group (86.9% vs. 53.8%, P<0.001). There were significant different toxicities in leukocytopenia, thrombocytopenia and increased total bilirubin level [P<0.001, P=0.013, P<0.01, relative risk (RR) 1.63, 1.33, 1.43], but no differences in severe AEs of upper GI hemorrhage and severe liver dysfunction between the groups (5.39% vs. 2.3%, P=0.136). Conclusions: Owing to excellent tumor-targeting, promised efficacy and favourable toxicity profile, the novel combination therapy of licartin and TACE could be applied in patients with unresectable HCC.
