AIM:To investigate the efficacy of transcatheter embolization/chemoembolization (TAE/TACE) in cirrhotic patients with single hepatocellular carcinoma (HCC) not suitable for surgical resection and percutaneous ablation therapy. METHODS:A cohort of 176 consecutive cirrhotic patients with single HCC undergoing TAE/TACE was reviewed; 162 patients had at least one image examination (helical CT scan or triphasic contrastenhanced MRI) after treatment and were included into the study. TAE was performed with Lipiodol followed by Gelfoam embolization; TACE was performed with Farmorubicin prepared in sterile drip at a dose of 50 mg/m2,infused over 30 min using a peristaltic pump,and followed by Lipiodol and Gelfoam embolization. RESULTS:Patients characteristics were:mean age,62 years; male/female 117/45; Child-Pugh score 6.2 ± 1.1; MELD 8.7 ± 2.3; mean HCC size,3.6 (range 1.0-12.0) cm. HCC size class was ≤ 2.0 cm,n = 51; 2.1-3.0 cm,n = 35; 3.1-4.0 cm,n = 29; 4.1-5.0 cm,n = 22; 5.1-6.0 cm,n = 11; and > 6.0 cm,n = 14. Patients received a total of 368 TAE/TACE (mean 2.4 ± 1.7). Complete tumor necrosis was obtained in 94 patients (58%),massive (90%-99%) necrosis in 16 patients (10%),partial (50%-89%) necrosis in 18 patients (11%) and poor (< 50%) necrosis in the remaining 34 patients (21%). The rate of complete necrosis according to the HCC size class was:69%,69%,52%,68%,50% and,13% for lesions of ≤ 2.0,2.1-3.0,3.1-4.0,4.1-5.0,5.1-6.0,and > 6.0 cm,respectively. Kaplan-Mayer survival at 24-mo was 88%,68%,59%,59%,45%,and 53% for lesions of ≤ 2.0,2.1-3.0,3.1-4.0,4.1-5.0,5.1-6.0,and > 6.0 cm,respectively. CONCLUSION:Our study showed that in cirrhotic patients with single HCC smaller than 6.0 cm,TAE/TACE produces complete local control of tumor in a significant proportion of patients. TAE/TACE is an effective therapeutic option in patients with single HCC not suitable for surgical resection or percutaneous ablation therapies. Further studies should investigate if the new available embolization agents or drug eluting beads may improve the effect on tumor necrosis. 展开更多

This study is aimed to evaluate the effectiveness and safety of the treatment of highflow priapism with superselective transcatheter embolization.From Sep.1999 to Jan.2013,six patients with high-flow priapism underwent superselective transcatheter embolization of the cavernous artery.Recurrence of priapism,and change in erectile function detected by nocturnal penile tumescence and rigidity(NPTR)test and the International Index of Erectile Function 5-item questionnaire(IIEF-5)were evaluated during a mean follow-up of 12 months.A single superselective transcatheter embolization was sufficient for complete resolution of priapism in the six patients.None of the patients had a relapse of priapism after embolization,and all the patients who had premorbid normal erectile function showed maintained potency with normal results of NPTR and a mean postoperative IIEF-5 score of 23.5(range 23 to 24)during the follow-up period.In conclusion,superselective transcatheter embolization is an effective and safe treatment method for high-flow priapism,and it can ensure a high level of preservation of premorbid erectile function. 展开更多

BACKGROUND Hepatocellular carcinoma(HCC)is a prevalent malignancy,and transcatheter arterial embolization(TAE)has emerged as a pivotal therapeutic modality.How-ever,TAE may induce symptom distress and fatigue,adversely affecting the quality of life of patients.AIM To investigate symptom distress,fatigue,and associated factors in HCC patients undergoing TAE.METHODS We used a cross-sectional design and purposive sampling to enroll HCC patients who underwent TAE at our institution from January to December 2022.Question-naires were utilized to collect data on symptom distress and fatigue scores from the first to the third day after TAE.RESULTS Our study revealed a significant reduction in fatigue and symptom distress among patients after TAE.Pain,fatigue,insomnia,fever and abdominal dis-tension were the most common symptoms troubling patients during the first 3 d post-TAE.Marital status,presence of family support,physical functional status,age,and symptom distress were identified as predictors of fatigue in patients.CONCLUSION Healthcare professionals should educate HCC patients on symptom distress and INTRODUCTION Hepatocellular carcinoma(HCC)ranks as the fifth most prevalent cancer and the third leading cause of cancer-related mortality globally.Surgical intervention remains the cornerstone of HCC treatment;however,due to the challenges associated with early diagnosis and the lack of specific diagnostic markers,a considerable proportion of patients are diagnosed at advanced stages,rendering them ineligible for surgical interventions.Transcatheter arterial embolization(TAE)is an interventional therapeutic approach involving the insertion of a fine catheter via the femoral artery to reach the vasculature near the tumor site.TAE aims to obstruct the arterial supply to the tumor by deploying embolic agents,thereby inducing necrosis in cancer cells.This procedure is suitable for patients with good liver function and overall health,particularly those with large HCCs that have not invaded the portal vein[1,2].Nonetheless,following TAE,hepatocytes incur variable degrees of damage,leading to the development of a constel-lation of symptoms reminiscent of acute hepatitis.These symptoms include fatigue and systemic discomfort,such as nausea,vomiting,fever,abdominal pain,as well as transient elevations in aspartate aminotransferase(AST)and alanine aminotransferase(ALT),collectively referred to as postembolization syndrome[3,4].These symptoms may arise due to ischemia of the liver and gallbladder,temporary liver enlargement,and peritoneal irritation.While many studies have explored fatigue and symptom distress in cancer patients both nationally and internationally,with some focusing on symptom distress following transcatheter arterial chemoembolization,there has been limited in-depth investigation into the fatigue and symptom distress resulting from TAE treatment[5-8].Fatigue and pain are both subjective experiences,typically arising from the gradual depletion of energy reserves during the course of illness[9].Fatigue is particularly prevalent among cancer patients,with rates soaring as high as 90%.Despite extensive research exploring cancer-related fatigue and its influencing factors,a unanimous consensus remains elusive.Hence,the primary objective of this study was to investigate the symptom distress and fatigue experienced by liver cancer patients following TAE treatment and to analyze potential contributing factors. 展开更多

BACKGROUND Transcatheter arterial embolization(TAE)has been widely used as an effective and a safe treatment method and was often used as an alternative to the surgical management,but there are limited studies on the efficacy and the safety for patients undergoing their secondary postpartum hemorrhage(PPH).AIM To evaluate the usefulness of TAE for secondary PPH focusing on the angiographic findings.METHODS We conducted a research from January 2008 to July 2022 on all 83 patients(mean:32 years,range:24-43 years)presented with secondary PPH and they were treated with TAE in two university hospitals.The medical records and angiography were retrospective reviewed in order to evaluate the patients’characteristics,delivery details,clinical status and peri-embolization management,angiography and embolization details,technical/clinical success and complications.The group with active bleeding sign and the group without it were also compared and analyzed.RESULTS On angiography,46(55.4%)patients showed active bleeding signs such as contrast extravasation(n=37)or pseudoaneurysm(n=8)or both(n=1),and 37(44.6%)patients showed non-active bleeding signs such as only spastic uterine artery(n=2)or hyperemia(n=35).In the active bleeding sign group there were more multiparous patients,low platelet count,prothrombin time prolongation,and high transfusion requirements.The technical success rates were 97.8%(45/46)in active bleeding sign group and 91.9%(34/37)in non-active bleeding sign group,and the overall clinical success rates were 95.7%(44/46)and 97.3%(36/37).An uterine rupture with peritonitis and abscess formation occurred to one patient after the embolization,therefore hysterostomy and retained placenta removal were performed which was a major complication.CONCLUSION TAE is an effective and a safe treatment method for controlling secondary PPH regardless of angiographic findings. 展开更多

AIM:To evaluate the efficacy and safety of emergency transcatheter arterial embolization (ETAE) for patients with acute massive duodenal ulcer hemorrhage. METHODS:Twenty-nine consecutive patients with acute massive bleeding of duodenal ulcer were admitted to our hospital from 2006 to 2011. Superselective angiography of the celiac and gastroduodenal arteries was performed to find out the bleeding sites before ETAE, then, embolotherapy was done with gelatin sponge particles or microstrips via a 5 French angio-graphic catheter or 3 French microcatheter. After ETAE, further superior mesenteric arteriography was under-taken in case collateral circulation supplied areas of the duodenal ulcer. Technical and clinical success rates were analyzed. Changes in the mucous membrane were observed using endoscopy following ETAE. RESULTS:Angiography showed active bleeding with extravasation of contrast medium in seven cases with a 24% positive rate of celiac artery bleeding, and in 19 cases with a 65.5% rate of gastroduodenal artery bleeding. There were no angiographic signs of bleeding in three patients who underwent endoscopy prior to ETAE. Twenty-six patients achieved immediate hemostasis and technical success rate reached 90%. No hemostasis was observed in 27 patients within 30 d after ETAE and clinical success rate was 93%. Recurrent hemorrhage occurred in two patients who drank a lot of wine who were treated by a second embolotherapy in the same way. Five patients underwent transient ischem with light abdominal pain under xiphoid, spontaneous restoration without special treatment. No mucous necrosis happened to 29 cases for ischem of gastroduodenal arteries embolized. CONCLUSION:ETAE is an effective and safe measure to control acute massive bleeding of duodenal ulcer. 展开更多

AIM: To retrospectively evaluate the prognosis of patients with hepatocellular carcinoma (HCC) with or without a history of therapy for HCC following transcatheter arterial embolization (TAE). METHODS: One hundred and twenty-one patients with HCC treated with TAE from 1992 to 2004 in our hospital were enrolled in this study. Eighty-four patients had a history of treatment for HCC, while 37 did not. At the time of entry, patients with extra-hepatic metastasis, portal vein tumor thrombosis, or Child-Pugh class C were excluded. TAE was repeated when recurrence of HCC was diagnosed by elevated tumor markers, or ultrasonography or dynamic computed tomography findings. RESULTS: Tumor size was larger and the number of tumors was fewer in patients without past treatment (P〈0.01). However, there were no differences in tumor node metastasis (TNM) stage or survival rate between the 2 groups. A bilobular tumor and high level of α-fetoprotein (AFP) (〉100 ng/mL) were factors related to a poor prognosis in patients with a history of HCC. CONCLUSION: The prognosis following TAE is similar between HCC patients with and without past treatment. Early diagnosis of HCC or recurrent HCC and obtaining good local control against HCC before entry to a repeated TAE course can improve prognosis. 展开更多

AIM:To evaluate the effects of combined radiofrequen-cy ablation and transcatheter arterial embolization with iodized oil on ablation time,maximum output,coagula-tion diameter,and portal angiography in a porcine liver model. METHODS: Radiofrequency ablation (RFA) was applied to in vivo livers of 10 normal pigs using a 17-gauge 3.0 cm expandable LeVeen RF needle electrode with or with-out transcatheter arterial embolization (TAE) with iodized oil (n = 5). In each animal,2 areas in the liver were ab-lated. Direct portography was performed before and af-ter RFA. Ablation was initiated at an output of 30 W,and continued with an increase of 10 W per minute until roll-off occurred. Ablation time and maximum output until roll-off,and coagulated tissue diameter were compared between the 2 groups. Angiographic changes on portog-raphy before and after ablation were also reviewed. RESULTS: For groups with and without TAE with iodized oil,the ablation times until roll-off were 320.6 ± 30.9 seconds and 445.1 ± 35.9 seconds,respectively,maxi-mum outputs were 69.0 ± 7.38 W and 87.0 ± 4.83 W and maximal diameters of coagulation were 41.7 ± 3.85 mm and 33.2 ± 2.28 mm. Significant reductions of abla-tion time and maximum output,and significantly larger coagulation diameter were obtained with RFA following TAE with iodized oil compared to RFA alone. Portography after RFA following TAE with iodized oil revealed more occlusion of the larger portal branches than with RFA alone. CONCLUSION: RFA following TAE with iodized oil can increase the volume of coagulation necrosis with lower output and shorter ablation time than RFA alone in nor-mal pig liver tissue. 展开更多

AIM: To evaluate the dinical outcome and cost-effectiveness of transcatheter arterial ethanol-lipiodoi embolotherapy on hepatocellular carcinoma (HCC). METHODS: One hundred patients with HCC who were treated only by lobar or segmental transarterial embolization (TAE) with ethanol-lipiodoi mixture were enrolled in this study. The 1st- and 2nd-year survival rates were analyzed to evaluate the feasibility of its method. These outcomes of our patients were individually correlated to the Child-Pugh classification and the computed tomographic features of HCC. RESULTS: The overall 1st- and 2nd-year survival rates were 72% and 46%, respectively. The patients were classified into three groups according to their liver function status: 68 patients as Child-Pugh class A, 26 as Child B, and 6 as Child C. Child A had better survival rate than the Child B and/or C. The 1st-year survival rates of patients with Child A-C were 84%, 50%, and 33.3% respectively and the 2nd-year survival rates were 55.5%, 28.5%, and 33.3%, respectively. According to the computed tomographic features, solitary HCC with maximum diameter less than 5 cm had the best outcome with the lst-year survival rate of 100% and the 2nd-year survival rate of 71.4%, while solitary HCC with maximum diameter over 5 cm and multiple HCC had the lst-year survival rates of 75% and 63.7%, respectively, and the 2nd-year survival rates of 33.3% and 44.4%, respectively. Only one patient was complicated with abscess formation and was cured with antibiotic therapy. No mortality resulted from the procedures performed. CONCLUSION: TAE with ethanol-lipiodoi mixture is an economic, safe and feasible method for treating HCC, especially for the patients with smaller solitary HCC or with liver function status of Child-Pugh class A. 展开更多

BACKGROUND Hepatic hemangioma is the most common benign tumor of the liver.However,patients with large hemangiomas that cause compression symptoms or that are at risk of rupture may need further intervention.It is necessary to explore additional minimally invasive and personalized treatment options for hemangiomas.CASE SUMMARY A 47-year-old woman was diagnosed with a right hepatic hemangioma for more than 10 years.Abdominal contrast-enhanced computed tomography(CT)and contrast-enhanced ultrasound revealed that there was a large hemangioma in the right liver,with a size of approximately 95 mm×97 mm×117 mm.Due to the patient's refusal of surgical treatment,hepatic artery embolization was performed in the first stage.After 25 d of liver protection treatment,the liver function indexes decreased to normal levels.Then,ultrasound-guided microwave ablation of the giant hepatic hemangioma was performed.Ten days after the treatment,hepatobiliary ultrasonography showed that the hemangioma of the right liver was smaller than the previous size(the volume was reduced by approximately 30%).Then the patient was discharged from the hospital.One year after discharge,CT showed that the hepatic hemangioma had shrunk by about 80%CONCLUSION Transcatheter arterial embolization combined with microwave ablation is a safe and effective minimally invasive treatment for hepatic hemangioma. 展开更多

AIM: To assesse changes in plasma HBV DNA after TAE in HBV-related HCC and correlate the levels with the pattern of lipiodol accumulation on CT. METHODS: Between April and June 2001, 14 patients with HBV-associated HCC who underwent TAE for inoperable or recurrent tumor were studied. Levels of plasma HBV DNA were measured by real-time quantitative PCR daily for five consecutive days after TAE. More than twofold elevation of circulating HBV DNA was considered as a definite elevation. Abdominal CT was performed 1-2 mo after TAE for the measurement of lipiodol retention. RESULTS: Circulating HBV DNA in 10 out of 13 patients was elevated after TAE, except for one patient whose plasma HBV DNA was undetectable before and after TAE. In group Ⅰ patients (n = 6), the HBV DNA elevation persisted for more than 2 d, while in group Ⅱ (n = 7), the HBV DNA elevation only appeared for i d or did not reach a definite elevation. There were no significant differences in age or tumor size between the two groups. Patients in group Ⅰ had significantly better lipiodol retention (79.31±28.79%) on subsequent abdominal CT than group Ⅱ (18.43±10.61%) (P = 0.02). CONCLUSION: Patients with durable HBV DNA elevation for more than 2 d correlated with good lipiodol retention measured 1 mo later, while others associated with poor lipiodol retention. Thus, circulating HBV DNA may be an early indicator of the success or failure of TAE. 展开更多

BACKGROUND Despite the improvement in the endoscopic hemostasis of non-variceal upper gastrointestinal bleeding(NVUGIB),rebleeding remains a major concern.AIM To assess the role of prophylactic transcatheter arterial embolization(PTAE)added to successful hemostatic treatment among NVUGIB patients.METHODS We searched three databases from inception through October 19th,2020.Randomized controlled trials(RCTs)and observational cohort studies were eligible.Studies compared patients with NVUGIB receiving PTAE to those who did not get PTAE.Investigated outcomes were rebleeding,mortality,reintervention,need for surgery and transfusion,length of hospital(LOH),and intensive care unit(ICU)stay.In the quantitative synthesis,odds ratios(ORs)and weighted mean differences(WMDs)were calculated with the random-effects model and interpreted with 95%confidence intervals(CIs).RESULTS We included a total of 3 RCTs and 9 observational studies with a total of 1329 patients,with 486 in the intervention group.PTAE was associated with lower odds of rebleeding(OR=0.48,95%CI:0.29–0.78).There was no difference in the 30-d mortality rates(OR=0.82,95%CI:0.39–1.72)between the PTAE and control groups.Patients who underwent PTAE treatment had a lower chance for reintervention(OR=0.48,95%CI:0.31–0.76)or rescue surgery(OR=0.35,95%CI:0.14–0.92).The LOH and ICU stay was shorter in the PTAE group,but the difference was non-significant[WMD=-3.77,95%CI:(-8.00)–0.45;WMD=-1.33,95%CI:(-2.84)–0.18,respectively].CONCLUSION PTAE is associated with lower odds of rebleeding and any reintervention in NVUGIB.However,further RCTs are needed to have a higher level of evidence. 展开更多

Objective:This study aimed to analyze the effects of transcatheter arterial embolization(TAE)combined with portal venous embolization(PVE)on the expression of MMP-2 in residual VX2 liver tumor tissues,liver function and non-embolic lobe regeneration.Methods:A total of 72 rabbits were randomly divided into Sham,TAE,PVE and TAE+PVE groups(n=18/group).The tissue samples from each group were taken at 6 h,3 days and 7 days after interventional operation,respectively.MMP-2 expression was detected by immunohistochemistry,Real-time PCR,and Western-blotting.The main indicators(such as AST,ATL,and TBIL)of liver function and the volume of non-embolized hepatic lobes were measured in each group after operation.One-way ANOVA and Kruskal-wallis method were used for statistical analysis.Results:The expression of MMP-2 mRNA and protein remained the highest in the Sham group,and the expression of MMP-2 mRNA and protein in TAE,PVE and TAE+PVE groups were successively increased,and the expression of MMP-2 in TAE+PVE group was always significantly higher than TAE group.The AST and ALT levels in each group on day 7 after operation showed a significant declination,and all groups have recovered to the preoperative baseline level and TBIL has a slight fluctuation in each group after operation with no statistical difference.On day 7 after operation,the increasing volume of non-embolized liver lobes in TAE+PVE group showed a more significant effect than those in PVE group,but there was no statistical significance(37.62±1.54 ml VS 36.18±1.15 ml,P=0.881),and its volume was significantly higher than those in the sham group(27.03±1.11 ml).Conclusion:TAE+PVE is considered to be an efficient and safe approach for treating rabbit VX2 liver transplantation tumor,but the expression of MMP-2 increased fastest after TAE+PVE,which might promote tumor cell invasion and metastasis. 展开更多

BACKGROUND Haematoma is one of the main complications associated with pacemaker implantation.Pseudoaneurysm is a rare condition that is not easy to identify and is often overlooked.CASE SUMMARY A female patient diagnosed with high-grade atrioventricular block underwent permanent pacemaker implantation.During the operation,puncturing a small branch of the right subclavian artery developed into a pseudoaneurysm and resulted in further haematoma formation.Conventional treatment of compression haemostasis and haemostatic drugs was not effective.A series of timely transcatheter arterial embolizations avoided serious complications.CONCLUSION More possible conditions should be taken into consideration as haematoma is discovered,and timely treatment might prevent severe adverse events. 展开更多

Objective: To estimate the safety and efficacy of transcatheter arterial embolization(TAE) in the treatment of refractory hematuria of prostatic origin(RHPO).Methods: This retrospective study included 23 patients who underwent TAE for RHPO between May 2013 and August 2021. Technical and clinical success rates were calculated, and arteriogram findings and complications were detected.Results: Embolization was performed 24 times in 23 patients. Technical success was achieved in 24/24(100%)embolization procedures. Contrast agent extravasation was detected during 2 of the 24 angiographic procedures.Bilateral embolization was performed in 23(95.8%) of the 24 procedures. The clinical success rate was 21/23(91.3%), and hematuria stopped 1–4 days after TAE. No serious complications were observed.Conclusion: TAE is a safe and effective minimally invasive technique for treating patients with RHPO. 展开更多

The data related to treatment and outcomes in this condition are scarce. We present a case series of four COVID-19 patients with lumbar artery bleeding, who were treated with transcatheter arterial embolization using embolization particles. The procedure was executed without any complications, and hemostasis was achieved in all four patients. Despite the patients survived the procedure, one patient died due to respiratory failure three weeks after the procedure, and one died due to hypovolemic shock two days later. Considering the ongoing state of COVID-19 pandemic, it is essential to be aware of transcatheter arterial embolization as a safe and effective procedure for treating retroperitoneal hemorrhage in COVID-19 patients. 展开更多

BACKGROUND Gastrointestinal bleeding(GIB)is a severe and potentially life-threatening condition,especially in cases of delayed treatment.Computed tomography angiography(CTA)plays a pivotal role in the early identification of upper and lower GIB and in the prompt treatment of the haemorrhage.AIM To determine whether a volumetric estimation of the extravasated contrast at CTA in GIB may be a predictor of subsequent positive angiographic findings.METHODS In this retrospective single-centre study,35 patients(22 men;median age 69 years;range 16-92 years)admitted to our institution for active GIB detected at CTA and further submitted to catheter angiography between January 2018 and February 2022 were enrolled.Twenty-three(65.7%)patients underwent endoscopy before CTA.Bleeding volumetry was evaluated in both arterial and venous phases via a semi-automated dedicated software.Bleeding rate was obtained from volume change between the two phases and standardised for unit time.Patients were divided into two groups,according to the angiographic signs and their concordance with CTA.RESULTS Upper bleeding accounted for 42.9%and lower GIB for 57.1%.Mean haemoglobin value at the admission was 7.7 g/dL.A concordance between positive CTA and direct angiographic bleeding signs was found in 19(54.3%)cases.Despite no significant differences in terms of bleeding volume in the arterial phase(0.55 mL vs 0.33 mL,P=0.35),a statistically significant volume increase in the venous phase was identified in the group of patients with positive angiography(2.06 mL vs 0.9 mL,P=0.02).In the latter patient group,a significant increase in bleeding rate was also detected(2.18 mL/min vs 0.19 mL/min,P=0.02).CONCLUSION In GIB of any origin,extravasated contrast volumetric analysis at CTA could be a predictor of positive angiography and may help in avoiding further unnecessary procedures. 展开更多

The hemodynamic changes of portal vein before and after intra arterial infusion of ethanol iodized oil emulsion (EIOE) were studied in 4 healthy dogs. Segmental transcatheter arterial embolization (TAE) using EIOE was performed in 55 patients with hepatocellular carcinoma (HCC). Twenty patients subsequently underwent surgery. It was concluded that segmental TAE might lead to double embolization of both hepatic arteries and portal veins. It is a more effective therapeutic method for HCC localized in one or a few segments, as compared with conventional TAE. 展开更多

Objective To evaluate preliminarily the therapeutic efficacy of transcatheter arterial embolization (TAE) for different histopathologic subtypes of primary hepatocellular carcinoma (HCC). Methods A retrospective study of 226 patients with histopathologically diagnosed primary HCC was performed. The patients were treated with either single TAE, surgical resection of tumor alone, or TAE combined with surgical resection. Follow up information was achieved in 157 of 226 patients. Comparative analyses of survival data and image findings were performed with correlation to histopathologic classification and different therapeutic methods,respectively. Results Eight histopathologic subtypes of primary HCC were found in this group, including HCC of trabecular pattern, pseudoglandular pattern, fibrolamellar HCC and sclerosing HCC, as well as HCC of clear cell, of small cell, poorly differentiated or undifferentiated HCC, and hormonally active HCC. The accumulated survival rate for these 157 patients was 74.52% of 1 year, 53.50% of 2 years, 31.85% and 14.01% of 3 and 5 years, respectively. Fibrolamellar HCC and clear cell HCC had relatively higher survival rate (25.00% and 33.22% of 5 years, respectively) than that of other subtypes, and the median survival time of the latter was 71 months. The mean survival time was 25.06 months (SE=1.87) in single TAE group, 30.38 (SE=2.05) months in surgical resection, and 72 months (SE=6.90) in TAE combined with resection. Conclusions Discrepancies do exist in therapeutic effect of different subtypes of HCC. In this study, clear cell HCC was more sensitive to TAE than other subtypes, and, in contrast, small cell HCC and poorly differentiated or undifferentiated HCC were of lower sensitivity to TAE. 展开更多
