Postoperative recurrence of hepatocellular carcinoma: Results of transcatheter arterial chemoembolization

A retrospective analysis was made of the effect of transcatheter arterial chemoembolization (TACE) in 87 patients with recurrent hepatocellular carcinoma (HCC). In contrast to the predominantly single nodular HCC (60.2%) on preoperative angiography, recurrent HCC showed a multinodular pattern in 54.2%. Preoperative TACE had significantly prolonged the interval between surgery and recurrence. One- and 2-year survival rates after TACE of the 87 recurrent HCCs were 74.7% and 55.%, respectively, which were not significantlydifferent from those of a control group of 206 patients with HCC in Child's class A, who were treated with TACE only. We believe that TACE is an effective measure in the management of preoperative and recurrent HCC.     

原发性肝癌肝动脉化疗碘油栓塞后的MRI诊断价值

目的 研究MRI检查技术，尤其是FSET2WI和多时相快速动态增强扫描评价原发性肝癌动脉化疗碘油栓塞后（TACE）的影像学表现，探讨其临床应用价值。方法收集2000年9月至2004年7月肝癌病例30例（共37个病灶），于TACE后2～6个月行GE1．5TMRI检查，并于MRI检查后2～6d行DSA检查。研究肝癌TACE后肿瘤的坏死或存活的MRI信号特点，以及MRI和DSA在显示肿瘤存活结果的符合情况。结果37个肝癌TACE术后病灶中，MRI明确判断21个病灶有肿瘤残存，16个病灶凝固坏死明显。MRI判断病灶残存的敏感性为91．3％，特异性100％，准确性94．6％。与DSA相比无明显统计学差异（P〉0．05）。结论FSET2WI和多时相快速动态增强扫描序列相结合，同时观察病灶周围的完整与否，可以准确地判断肝癌TACE后肿瘤的坏死或残存。作为一种无创伤性检查。可以作为评价肝癌TACE术后疗效的首选检查。     

Angiographic evaluation of hepatic arterial damage after transarterial chemoembolization for hepatocellular carcinoma

PURPOSE: The aim of this study was to assess the incidence, degree, and predictors of hepatic arterial damage (HAD) after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: A total of 33 patients with unresectable HCC underwent TACE alone using a mixture of iodized oil, epirubicin, and gelatin sponge. A follow-up angiogram was available for 76 of 109 sessions, and HAD was evaluated at each subsegment of the hepatic artery using a three-grade scale (1, no or slight wall irregularity; 2, overt stenosis; 3, occlusion). Grades 2 and 3 were considered to indicate significant HAD. The predictors of HAD were analyzed by multivariate analysis. RESULTS: A total of 161 hepatic arteries were embolized from the lobar (n = 43), segmental (n = 40), subsegmental (n = 72), or more distal (n = 6) level. The follow-up period between the initial and last sessions ranged from 70 to 1505 days (median 497 days). Significant HAD occurred in 37 of 231 subsegmental hepatic arteries (16%) and in 16 of 33 patients (48%). The accumulated dose of epirubicin per artery (P = 0.001) and Child-Pugh score (P < 0.001) were significant predictors. CONCLUSION: TACE is more likely to induce HAD in cirrhotic patients with impaired liver function and when a high dose of the chemotherapeutic agent was used.     

Effective segmental chemoembolization of advanced hepatocellular carcinoma with tumor thrombus in the portal vein

Purpose: Evaluate therapeutic results of transcatheter segmental hepatic artery chemo-oily-embolization (segmental TAE) against advanced hepatocellular carcinomas (HCC) accompanied by portal tumor thrombus (PTT). Methods: Segmental TAE was performed in nine patients with hepatic cirrhosis and advanced HCCs accompanied by PTT. Four subsegmental portal branches were obstructed by PTT in three patients, and two were obstructed in the remaining six patients. TAE was performed into the targeted segmental hepatic artery followed by embolization with gelatin sponge particles. Results: In one patient undergoing subsequent resection, a marked anticancer effect on the PTT was demonstrated histologically. In the eight other patients who did not undergo subsequent resection, the cumulative survival rates were 67% at 6 months, 44% at 1 year, and 22% at 2 years. No serious complications were noted. Conclusions: This therapeutic approach is thought to be a useful treatment for HCC with PTT, because it reinforces anticancer effects and can be performed more safely than conventional transcatheter arterial embolization.     

Embolization of the hepatic falciform artery to prevent supraumbilical skin rash during transcatheter arterial chemoembolization for hepatocellular carcinoma

A dilated hepatic falciform artery (HFA) arising from the left hepatic artery was demonstrated on arteriography prior to chemoembolization of an unresectable hepatocellular carcinoma (HCC) located predominantly in the left lobe of the liver. The HFA was occluded by microcoils to prevent a possible toxic supraumbilical skin rash following chemoembolization of the HCC via the left hepatic artery. There were no postprocedure complications. We consider this procedure useful for improving the safety of chemoembolization.     

经导管动脉化疗栓塞治疗肝癌导致短暂失明一例

报道1例TACE导致视觉障碍的病例.　患者男,38岁.因原发性肝癌从2001年10月到2002年3月先后3次在本院行经导管动脉化疗栓塞（TACE）治疗,即在供血动脉内注入碘油-化疗药物乳化剂,然后用明胶海绵（GS）颗粒或聚乙烯醇微球行肿瘤供血动脉栓塞.由于肿瘤近膈面,碘油沉积不佳,而膈动脉又没有显示明确的供血,因此同时采用经皮肝穿刺将碘油-化疗药物乳化剂注射到肿瘤的碘油缺损区.

Fatal septic complication of transcatheter chemoembolization for hepatocellular carcinoma

A patient with hepatocellular carcinoma, associated segmental portal vein thrombosis, and accompanying pneumobilia, developed a liver abscess and sepsis following transcatheter chemoembolization (TCE). It was believed that the combination of bile duct necrosis after arterial occlusion and pneumobilia led to ascending enteric infection and seeding of the necrotic tumor, which ultimately led to fatal outcome. We conclude that TCE is contraindicated in such cases.     

Transcatheter arterial chemoembolization in patients with hepatocellular carcinoma and coexisting hepatic cavernous hemangioma

We investigated the consequence of repeated transcatheter arterial chemoembolization (TACE) for coexisting small hepatic hemangioma in the treatment of patients with hepatocellular carcinomas and describe the imaging features of embolized hemangioma on the follow-up Lipiodol CT and MR. Six of 431 patients with biopsy-confirmed hepatocellular carcinomas, who underwent TACE, also had seven small hepatic cavernous hemangiomas (0.8∼2.3 cm) in the same area of embolization. All six patients underwent repeated TACE All lesions were evaluated with CT and/or MR for the post-treatment follow-up. The outcomes and imaging features of these embolized hemangiomas were reviewed for the change of tumor size, Lipiodol deposition, enhancing pattern as well as embolization complications. Six of the seven hemangiomas did not depict changes in the size or enhancement pattern without being ablated. One hemangioma showed a decrease in size, but still persisted after TACE. All of the hemangiomas showed Lipiodol deposition for 2∼15 months, in which five hemangiomas depicted irregular rim patterns. There is no complication caused by the procedures. The differentiation of small hepatic hemangiomas from viable HCC is important in the post-TACE follow-up to avoid unnecessary repeated embolization.
