The value and limitation of transcatheter arterial chemoembolization in preventing recurrence of resected hepatocellular carcinoma

AIM: To evaluate the value and limitation of postoperative transcatheter arterial chemoembolization (TACE) in preventing recurrence of hepatocellular carcinoma (HCC). METHODS: In the first group, 987 postoperative patients with HCC, who did not have any evidence of recurrence in the first preventative TACE but were found to have recurrence at different times during the follow-up survey, were analyzed. In the second group, 643 postoperative patients with HCC had no TACE for compared study. To study the relationship between the recurrence time and the number of TACE treatments was analyzed. RESULTS: The 6-, 12-, and 18-mo recurrence rates in the first and second groups were 22.2% (210 cases) vs 61.6% (396 cases), 78.0% (770 cases) vs 74.7% (480 cases) and 88.6% (874 cases) vs 80.1% (515 cases). There were significant differences between the recurrence rates of the two groups at 6 mo (P<0.0001). CONCLUSION: The principal role of TACE after HCC operation is to suppress, detect early and treat micro-metastasis. It has a good effect of preventing recurrence of HCC in 6 mo, but such an effect is less satisfactory in a longer period. When it is uncertain whether HCC is single-central or multi-central and if there is cancer residue or metastasis after operation, TACE is valuable to prevent recurrence.     

A case of hepatocellular carcinoma with bleeding gingival metastasis treated by transcatheter arterial embolization

The patient was a terminally ill 80-year-old man with multiple lung metastases from hepatocellular carcinoma, that had developed following hepatitis-C virus-associated cirrhosis. He was admitted to our hospital with gingival bleeding, and we diagnosed gingival metastasis from hepatocellular carcinoma, based on histological examination. The bleeding could not be controlled, and the patient became dyspneic. After transcatheter arterial embolization, his bleeding was successfully controlled until his death due to respiratory failure. Transcatheter arterial embolization was a safe and effective treatment in our case.     

Survival outcome of lobar or segmental transcatheter arterial embolization with ethanol-lipiodol mixture in treating hepatocellular carcinoma

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.     

Alpha-fetoprotein in patients with hepatocellular carcinoma after transcatheter arterial embolization

To assess the usefulness of alpha-fetoprotein (AFP) in monitoring treatment effects of transcatheter arterial embolization (TAE) in hepatocellular carcinoma (HCC) patients, a total of 31 sets of AFP levels after TAE in 21 HCC patients were analysed by linear regression between logarithmic AFP levels and days. Eleven sets of AFP data with poor linear declination were accompanied with poor TAE results except in one patient who had chronic hepatitis with acute exacerbations. Twenty sets of data with good linear declination in the first month after TAE indicated good TAE results. Seven of them showed no evidence of tumour recurrence nor elevated AFP levels within a follow-up of 6 months. The mean, standard deviation and range of half-lives of AFP in the non-recurrent group were 5.0, 1.6 and 2.9-7.2 days, respectively. The others experienced late tumour recurrence that was detected by rebound of AFP levels except one who had another non-AFP-secreting HCC. Thus, the results might be used as a reference in monitoring the treatment effects of TAE and the timing selection of repeated TAE.     

Angioechographic evaluation of tumor thrombi and the effect of transcatheter arterial embolization in patients with hepatocellular carcinoma

Background: Background: Transcatheter arterial embolization (TAE) is considered to be relatively ineffective in the treatment of portal and/or hepatic vein tumor thrombi associated with hepatocellular carcinoma (HCC). However, we have seen patients with a positively enhanced tumor thrombus on angioechography where necrosis has occurred after TAE. In this study, we compared the angioechographic enhancement of tumor thrombi with the effect of TAE to assess the use of this method in predicting the efficacy of TAE, and in predicting survival. Methods: Angioechography, using a small amount of CO₂ gas injected into the hepatic artery, was performed before TAE in 41 HCC patients with tumor thrombi of the portal vein (PVTT; n= 35) or hepatic vein (HVTT; n= 6). The relationship between the enhancement of the thrombi and the efficacy of TAE was investigated by follow-up ultrasonography. Results: All 13 PVTT that decreased in size had shown positive enhancement (PE) before treatment (P < 0.001), while 6 of the 7 cases (86%) in which the lesions increased in size had shown negative enhancement (NE). The survival of patients with PE was significantly longer than that of patients with NE (P < 0.005). Multivariate analysis identified two clinical variables associated with survival, angioechographic findings of PVTT, and age. There were no correlations between enhancement and HVTT. Conclusions: Determination of enhancement of PVTT on angioechography was useful in predicting the efficacy of TAE treatment of HCC and the survival time. Angioechography may be valuable in treatment decisions for HCC patients with PVTT, especially as a guide to the effectiveness of TAE. Received: March 1, 2001 / Accepted: November 2, 2001     

肝癌动脉化疗栓塞效果的病理评价

目的研究肝细胞癌经动脉化疗栓塞治疗后癌肿的变化，探索提高疗效的方法。方法对动脉化疗栓塞治疗后行手术的３９例肝癌和１１例对照标本进行坏死程度与包膜、治疗次数、病理类型、分化、血管损伤及淋巴细胞浸润诸因素相关性的分析。结果完全坏死者６例，３０％＿９５％坏死者１４例，仅５％坏死及无坏死者１９例，１１例ＤＳＡ无坏死。癌肿坏死程度与肿癌分化、治疗次数、淋巴细胞浸润无关，而与病理类型、包膜、血管损伤有关。结论肝癌动脉化疗栓塞是中晚期肝癌目前唯一可取的治疗方法。对于有包膜的肝细胞癌，只要治疗能达到癌肿部位，即使一次治疗，也可收到明显的效果。对于如何使每例都达到彻底的癌肿坏死是值得进一步探讨的。     

Two cases of hemosuccus pancreaticus in which hemostasis was achieved by transcatheter arterial embolization

Hemosuccus pancreaticus is a rare complication of chronic pancreatitis. We report two cases of hemosuccus pancreaticus in which hemostasis was achieved by transcatheter arterial embolization (TAE). The first patient was a 47-year-old man with alcoholic chronic pancreatitis. He presented with upper abdominal pain and hematemesis. Upper GI endoscopy failed to detect the source of bleeding, but computed tomography (CT) showed a hypervascular area about 3?cm in diameter in a pseudocyst at the pancreatic tail. Angiography revealed a pseudoaneurysm in the caudal pancreatic artery. Hematemesis was considered to be due to rupture of the pseudoaneurysm. TAE of the splenic artery was performed selectively, and this successfully stopped the bleeding. The second patient was a 52-year-old man with alcoholic chronic pancreatitis. He presented with hematemesis. Upper GI endoscopy detected bleeding from the papilla of Vater. CT showed hemorrhage in a pseudocyst at the pancreatic body. Angiography revealed angiogenesis around the pseudocyst. Hematemesis was considered to result from rupture of the pseudoaneurysm. TAE of the dorsal pancreatic artery and posterior superior pancreaticoduodenal artery was performed and hemostasis was achieved. We conclude that TAE is a minimally invasive and highly effective treatment for hemosuccus pancreaticus.     

Successful treatment of multiple hepatocellular adenomas with percutaneous radiofrequency ablation

Hepatocellular adenoma(HCA)is one of the important complications of glycogen storage disease typeⅠa(GSD-Ⅰa)because it can be transformed into hepatocellular carcinoma.Although surgical resection is a standard treatment of choice for solitary HCA,multiple HCAs in GSD-Ⅰa patients present as therapeutic challenges for curative treatment.Therefore,treatment strategy according to malignant potential is important in management of HCAs in GSD-Ⅰa.The authors present a case of histologically proven multiple HCAs withoutβ-catenin mutations occurred in a GSD-Ⅰa patient treated successfully with percutaneous radiofrequency ablation as a minimally invasive therapy.     

A case of lateral abdominal wall hematoma treated with transcatheter arterial embolization

Paracentesis is a diagnostic, therapeutic procedure performed in patients with ascites. It is generally thought to be a safe procedure and transfusion of platelet concentrate or fresh frozen plasma is not recommended before the procedure, because the incidence of clinically significant bleeding is very low. We report a case of lateral abdominal wall hematoma due to the injury of the deep circumflex iliac artery after paracentesis in patient with alcoholic liver cirrhosis who was treated with transcatheter arterial embolization.     

Intra-arterial carbon dioxide-enhanced ultrasonogram of hepatocellular carcinoma treated by transcatheter arterial embolization and percutaneous ethanol injection therapy

The purpose of this study was to investigate the value of carbon dioxide-enhanced ultrasonography (CO₂-US) in the evaluation of viable hepatocellular carcinomas (HCC) which were treated by transcatheter arterial embolization (TAE), percutaneous ethanol injection (PEI), or a combination treatment (TAE and PEI). Forty-one patients with 66 HCC were included in the study. They underwent CO₂-US and angiography were performed in all tumours after they were treated by TAE, PEI or a combination treatment. Forty-six tumours were positively enhanced by CO₂-US and 40 of them were positive by angiography. These 46 tumours were proved to be viable tumours either by biopsy or by follow-up studies. The positive predictive value was 100% for CO₂-US and 87.8% in angiography. Twenty tumours were negative by CO₂-US and these were also negative by angiography. Carbon dioxide-enhanced ultrasonography is a more reliable method for detecting the viable portion of the treated HCC compared with conventional angiography.     

Co-existence of hepatocellular adenoma and focal nodular hyperplasia in a young female

Focal nodular hyperplasia (FNH) and hepatocellular adenoma (HA) are both benign hepatocellular lesions, presenting mainly in women of childbearing age in non-cirrhotic, non-fibrotic livers. Simultaneous occur-rence of these two lesions is extremely rare. We herein report a case of a young female without any predis-posing risk factors who presented to our emergency department complaining of acute abdominal pain. Imaging studies revealed a 6 cm lesion in the right hepatic lobe and a 2.5 cm lesion in the left hepatic lobe, respectively. In view of the patient’s symptoms and lack of a confirmed diagnosis based on imaging, we performed a bisegmentectomy Ⅴ-Ⅵ and a wedge resection of the lesion in segment Ⅲ by laparotomy. Postoperative course was uneventful and the patient was discharged on the fourth postoperative day. The pathology report demonstrated an HA in segments Ⅴ-Ⅵ and FNH in segment Ⅲ, respectively. Six months later, the patient remains asymptomatic with normal liver function tests, ultrasound and magnetic reso-nance imaging follow-up. To our best knowledge, this is the first case to describe simultaneous occurrence of HA and FNH without the presence of any known risk factors for these entities. The uncertainty in diagnosis and acuteness of presenting symptoms were estab-lished criteria for prompt surgical intervention.     

Combined treatment of hepatocellular carcinoma with partial splenic embolization and transcatheter hepatic arterial chemoembolization

AIM: To prospectively evaluate the effi cacy and safety of partial splenic embolization (PSE) combined with transcatheter hepatic arterial chemoembolization (TACE) in treatment of hepatocellular carcinoma (HCC). METHODS: Fifty patients suffering from primary HCC associated with hypersplenism caused by cirrhosis were randomly assigned to 2 groups: group A receiving PSE combined with TACE (n = 26) and group B receiving TACE alone (n = 24). Follow-up examinations included calculation of peripheral blood cells (leukcytes, platelets and red blood cells) and treatment-associated complications. RESULTS: Prior to treatment, there was no signifi cant difference in sex, age, Child-Pugh grade, tumor diameter, mass pathology type and peripheral blood cell counts between the 2 groups. After treatment, leukocyte and platelet counts were significantly higher in group A during the 3-mo follow-up period (P < 0.05), but lower in group B (P < 0.05). Severe complications occurred in 3 patients (11.5%) of group A and in 19 patients (79.2%) of group B (P < 0.05), and there was no significant difference in symptoms of post-embolization syndrome, including abdominal pain, fever, mild nausea and vomiting between the 2 groups (P > 0.05). CONCLUSION: PSE combined with TACE is more effective and safe than TACE alone for patients with HCC associated with hypersplenism caused by cirrhosis.

Spectrum of anemia associated with chronic liver disease

Anemia of diverse etiology is a common complication of chronic liver diseases. The causes of anemia include acute or chronic gastrointestinal hemorrhage, and hypersplenism secondary to portal hypertension. Severe hepatocellular disease predisposes to hemorrhage because of impaired blood coagulation caused by deficiency of blood coagulation factors synthesized by hepatocytes, and/or thrombocytopenia. Aplastic anemia, which is characterized by pancytopenia and hypocellular bone marrow, may follow the development of hepatitis. Its presentation includes progressive anemia and hemorrhagic manifestations. Hematological complications of combination therapy for chronic viral hepatitis include clinically significant anemia, secondary to treatment with ribavirin and/or interferon. Ribavirin- induced hemolysis can be reversed by reducing the dose of the drug or discontinuing it altogether. Interferons may contribute to anemia by inducing bone marrow suppression. Alcohol ingestion is implicated in the pathogenesis of chronic liver disease and may contribute to associated anemia. In patients with chronic liver disease, anemia may be exacerbated by deficiency of folic acid and/or vitamin B12 that can occur secondary to inadequate dietary intake or malabsorption.     

A case of primary splenic angiosarcoma with intraperitoneal hemorrhage treated by transcatheter arterial embolization

Splenic tumors are very rare. In Japan only 42 cases of splenic angiosarcoma have been reported. We encountered a case of spontaneous rupture of a splenic angiosarcoma and liver metastasis. A 60-year-old woman who suddenly went into hemorrhagic shock presented at our hospital. Then acute spontaneously ruptured spleen and hepatic tumors were diagnosed by abdominal CT. After emergency TAE, the patient was hemodynamically stable, but died of liver failure 13 days after admission. The pathological diagnosis was primary splenic angiosarcoma with multiple organ metastasis on autopsy. Splenic angiosarcoma should be kept in mind in the differential diagnosis of splenomegaly or splenic tumor. TAE can be effective in primary hemostasis for angiosarcoma with intraperitoneal hemorrhage from multiple tumors.
