Evaluation of short-term effects of drug-loaded microspheres and traditional transcatheter arterial chemoembolization in the treatment of advanced liver cancer

BACKGROUND Liver cancer is a malignant tumor with high morbidity and mortality.Transcatheter arterial chemoembolization(TACE)is the main method for surgically unresectable liver cancer.In recent years,drug-loaded microspheres have been gradually applied in TACE technology.There are some controversies about the therapeutic effects of drug-loaded microspheres TACE(D-TACE)and traditional TACE.AIM To explore the short-term efficacy of D-TACE and traditional TACE in the treatment of advanced liver cancer.METHODS The clinical data of 73 patients with advanced liver cancer admitted to the First and Sixth Medical Centers of Chinese PLA General Hospital from January 2017 to October 2019 were retrospectively analyzed.Among them,15 patients were treated with D-TACE,and 58 patients were treated with traditional TACE.Clinical baseline characteristics,perioperative laboratory indices,postoperative adverse reactions and postoperative complications were compared between the two groups.RESULTS There was no statistical difference between the two groups for the postoperative response:The highest postoperative body temperature of the drug-loaded microsphere group was 38.0±0.9℃and the postoperative highest body temperature of the traditional TACE group was 38.3±0.7℃(t=-1.414,P=0.162).For the 24 h postoperative nausea and vomiting after surgery in terms of scoring and postoperative pain scores,the traditional TACE group was higher than the drugloaded microsphere group(χ2=14.33,P=0.014;χ2=32.967,P=0.000)and the two groups had significant statistical differences.The disease control rate at 3 mo after treatment in the drugloaded microsphere group was 60%and the disease control rate at 3 mo after treatment in the traditional TACE group was 75.9%(χ2=4.091,P=0.252).There was no statistical difference between the two groups of data.During the follow-up period,the number of interventional treatments received was once in the drug-loaded microsphere group and the traditional TACE group received an average of 1.48 treatments(χ2=10.444 P=0.005).There was a statistical difference between the two groups.CONCLUSION Compared with traditional TACE,D-TACE may have some advantages in the treatment of advanced hepatocellular carcinoma with a large tumor load in the short term,but the long-term clinical efficacy needs additional follow-up studies.In addition,compared with the traditional group,the patients in the drug-loaded microsphere group had better subjective tolerance and could reduce the number of interventional treatments.Therefore,D-TACE is worthy of clinical promotion.

Transarterial chemoembolization using degradable starch microspheres and iodized oil in the treatment of advanced hepatocellular carcinoma: evaluation of tumor response, toxicity, and survival

BACKGROUND: In a multidisciplinary conference patients with advanced non-resectable hepatocellular carcinoma (HCC) were stratified according to their clinical status and tumor extent to different regional modalities or to best supportive care. The present study evaluated all patients who were stratified to repeated transarterial chemoembolization (TACE) from 1999 until 2003 in terms of tumor response, toxicity, and survival. A moderate embolizing approach was chosen using a combination of degradable starch microspheres (DSM) and iodized oil (Lipiodol) in order to combine anti-tumoral efficiency and low toxicity. METHODS: Fourty-seven patients were followed up prospectively. TACE treatment consisted of cisplatin (50 mg/m2), doxorubicin (50 mg/m2), 450-900 mg DSM, and 5-30 ml Lipiodol. DSM and Lipiodol were administered according to tumor vascularization. Patient characteristics,toxicity, and complications were outlined. In multivariate regression analyses of pre-treatment variables from a prospective database, predictors for tumor response and survival after TACE were determined. RESULTS: 112 TACE courses were performed (2.4±1.5 courses per patient). Mean maximum tumor size was 75 (± 43) mm, in 68% there was bilobar disease. Best response to TACE treatment was: progressive disease (PD) 9%, stable disease (SD) 55%, partial remission (PR) 36%, and complete remission (CR) 0%. Multivariate regression analyses identified tumor size ≤75 mm, tumor number ≤5, and tumor hypervascularization as predictors for PR. The overall 1-, 2-, and 3-year-survival rates were 75%, 59%, and 41%, respectively, and the median survival was 26 months. Low α-fetoprotein levels (<400 ng/ml) (Odds ratio=3.3) and PR as best response to TACE (Odds ratio=6.7) were significantly associated with long term survival (>30 months, R2=36%). Grade 3 toxicity occurred in 7.1% (n=8), and grade 4 toxicity in 3.6% (n=4) of all courses in terms of reversible leukopenia and thrombocytopenia. The incidence of major complications was 5.4% (n=6). All complications were managed conservatively. The mortality within 6 weeks after TACE was 2.1% (one patient). CONCLUSIONS: DSM and Lipiodol were combined successfully in the palliative TACE treatment of advanced HCC resulting in high rates of tumor response and survival at limited toxicity. Favourable tumor response was associated with tumor extent and vascularization. TACE using DSM and Lipiodol can be considered a suitable palliative measure in patients who might not tolerate long acting embolizing agents.

Efficacy of transcatheter arterial chemoembolization using pirarubicin-loaded microspheres combined with lobaplatin for primary liver cancer

BACKGROUND Drug-eluting beads show good safety and promising efficacy when used as part of a transarterial chemoembolization regimen for primary liver cancer.However,data on the clinical efficacy and safety of pirarubicin-loaded beads combined with lobaplatin are lacking in China.AIM To evaluate the efficacy and safety of transcatheter arterial chemoembolization using pirarubicin-loaded beads combined with lobaplatin for primary liver cancer.METHODS Between January 2019 and March 2020,60 patients with primary liver cancer were selected at Hebei North University Affiliated First Hospital.According to different treatment methods,the participants were categorized into two groups with 30 patients treated with pirarubicin-loaded microspheres combined with lobaplatin included in an observation group and 30 patients treated with pirarubicin emulsion with lipiodol combined with lobaplatin were included in a control group.The progression-free survival,overall survival,clinical response rate,disease control rate,liver and kidney function and adverse reactions were compared between the two groups.RESULTS The progression-free survival was 14 mo in the observation group,which was significantly higher than 9 mo of the control group(P<0.05).The 6-mo,12-mo and 18-mo survival rates were 93.33%(28/30),66.67%(20/30)and 23.33%(7/30),respectively in the observation group,which were significantly higher than 83.33%(25/30),50.00%(15/30)and 13.33%(4/30),respectively,of the control group(all P<0.05).The clinical efficacy rate and disease control rate were 73.33%and 93.33%,respectively,in the observation group,which were significantly higher than those of the control group(53.55%and 80.00%,respectively,all P<0.05).There was no significant difference in alpha-fetoprotein between the two groups before the treatment(P>0.05).After the treatment,alpha-fetoprotein was 289.06±76.21 ng/m L in the observation group and 365.01±73.11 ng/m L in the control group,which were low in both groups compared with those before the treatment(all P<0.05).The incidence of nausea and vomiting was significantly lower in the observation group than in the control group(P<0.05).There was no significant difference for the adverse reactions of pain and fever between the two groups(P<0.05).CONCLUSION The combination of pirarubicin-loaded beads and lobaplatin can improve treatment efficacy resulting in mild liver function damage and postoperative complications in patients with primary liver cancer.It can be used in clinical practice.

Transarterial chemoembolization with pirarubicin-eluting microspheres in patients with unresectable hepatocellular carcinoma: Preliminary results

Purpose:To present the early results of pirarubicin-eluting microsphere transarterial chemoembolization(PETACE)for patients with unresectable hepatocellular carcinoma(HCC).Materials and methods:We retrospectively analyzed 55 consecutive patients with HCC who received PE-TACE between April 1,2015 and August 30,2016.The complication rate,tumor response rate,progression-free survival(PFS),and overall survival(OS)were analyzed.Results:Adverse events were generally mild and included abdominal pain and fever,although a major complication was reported in 1 patient(1.8%).During a median follow-up of 10.0 months(range,3.0-24.0 months),14 patients(25.5%)achieved a complete tumor response,25(45.5%)had a partial response,9(16.4%)showed stable disease,and 7(12.7%)had disease progression.The 1-month overall response rate was 70.9%,and the local tumor response rate was 89.0%.The 1-month tumor response rate was 100%for Barcelona Clinic Liver Cancer(BCLC)stage A or B disease and 62.8%for BCLC stage C disease.The median PFS was 6.1 months(95%confidence interval[95%CI],3.4-8.8 months;range,1.0-24.0 months).The median OS was 11.0 months(95%CI,7.1-14.9 months;range,2.0-24.0 months).Kaplan-Meier analysis(log-rank test)found significant differences in OS between patients grouped by tumor number(P=0.006),tumor size(P=0.035),and Eastern Cooperative Oncology Group(ECOG)score(P=0.005).The tumor number(1 vs.>2)was the only factor independently associated with OS(hazard ratio[HR],2.867;95%CI,1.330-6.181;P=0.007).Conclusions:PE-TACE for unresectable HCC may be safe,with favorable tumor response rates and survival time,especially in patients with a single large tumor.Longer follow-up using a larger series is necessary to confirm these preliminary results.

Regorafenib-loaded poly(lactide-co-glycolide) microspheres designed to improve transarterial chemoembolization therapy for hepatocellular carcinoma

Transarterial chemoembolization(TACE)has been widely introduced to treat hepatocellular carcinoma(HCC)especially for unresectable patients for decades.However,TACE evokes an angiogenic response due to the secretion of vascular endothelial growth factor(VEGF),resulting in the formation of new blood vessels and eventually tumor recurrence.Thus,we aimed to develop regorafenib(REGO)-loaded poly(lactide-co-glycolide)(PLGA)microspheres that enabled localized and sustained drug delivery to limit proangiogenic responses following TACE in HCC treatment.REGO-loaded PLGA microspheres were prepared using the emulsion-solvent evaporation/extraction method,in which DMF was selected as an organic phase co-solvent.Accordingly,we optimized the proportion of DMF,which the optimal ratio to DCM was 1:9(v/v).After preparation,the microspheres provided high drug loading capacity of 28.6%,high loading efficiency of 91.5%,and the average particle size of 149μm for TACE.IR spectra and XRD were applied to confirming sufficient REGO entrapment.The in vitro release profiles demonstrated sustained drug release of microspheres for more than 30 d To confirm the role of REGO-loaded microspheres in TACE,the cell cytotoxic activity on HepG2 cells and anti-angiogenic effects in HUVECs Tube-formation assay were studied in combination with miriplatin.Moreover,the microspheres indicated the potential of antagonizing miriplatin resistance of HepG2 cells in vitro.Pharmacokinetics preliminary studies exhibited that REGO could be sustainably released from microspheres for more than 30d after TACE in vivo.In vivo anti-tumor efficacy was further determined in HepG2 xenograft tumor mouse model,demonstrating that REGO microspheres could improve the antitumor efficacy of miriplatin remarkably compared with miriplatin monotherapy.In conclusion,the obtained REGO microspheres demonstrated promising therapeutic effects against HCC when combined with TACE.

Downstaging disease in patients with hepatocellular carcinoma outside up-to-seven criteria: Strategies using degradable starch microspheres transcatheter arterial chemo-embolization

AIM: To evaluate the downstaging rates in hepatitis C virus-patients with hepatocellular carcinoma(HCC), treated with degradable starch microspheres transcatheter arterial chemoembolization(DSM-TACE), to reach new-Milan-criteria(nM C) for transplantation. METHODS: This study was approved by the Ethics Committee of our institution. From September 2013 to March 2014 eight patients(5 men and 3 women) with liver cirrhosis and multinodular HCC, that did not meet n MC at baseline, were enrolled in this study. Patients who received any other type of treatment such as termal ablation or percutaneous ethanol injection were excluded. DSM-TACE was performed in all patients using Embo Cept? S and doxorubicin. Baseline and follow-up computed tomography or magnetic resonance imaging was assessed measuring the longest enhancing axial dimension of each tumor according to the modified Response Evaluation Criteria In Solid Tumors measure-ments, and medical records were reviewed.RESULTS: DSM-TACE was successfully performed in all patients without major complication. We treated 35 lesions(mean 4.3 per patient). Six of eight patients(75%) had their HCC downstaged to meet nM C. Every patient whose disease was downstaged eventually underwent transplantation. The six patients who received transplant were still living at the time of this writing, without recurrence of HCC. Baseline age(P = 0.25), Model for End-stage Liver Disease score(P = 0. 77), and α-fetoprotein level(P = 1.00) were similar between patients with and without downstaged HCC. CONCLUSION: DSM-TACE represents a safely and effective treatment option with similar safety and efficacy of conventional chemoembolization and could be successfully performed also for downstaging disease in patients without n MC, allowing them to reach liver transplantation.
