Indications for hepatectomy for hepatocellular carcinoma — What stage of the disease is the best indication for surgery?

To determine the clinical and tumor stage of hepatocellular carcinoma (HCC) that is the best indication for surgery, the postoperative long-term outcomes of patients who underwent hepatic resection were examined retrospectively. Of 975 patients with HCC who underwent regional therapy, 384 patients (39%) received hepatic resection (HR), 534 (55%) had transcatheter arterial chemoembolization (TACE), and the remaining 57 (6%) received percutaneous ethanol injection (PEI) into the tumor. The criteria defined by liver Cancer Study Group of Japan was used for staging and liver functional reserve (i.e., clinical staging).¹ In the 133 patients with stage I HCC, there were no significant differences among the survivals of the HR, TACE, and PEI groups. In the 314 patients with stage II HCC, the 5- and 7-year survival rates were 51% and 46% in the HR group, 23% and 10% in the TACE group, and 0% and 0% in the PEI group. The survival of the HR group was significantly better than the survivals of the TACE and PEI groups (P < 0.001). The 5- and 10-year survivals of the stage II HCC patients who had HR were 64% and 47% in the clinical stage I (i.e., good liver function) group, significantly better than the 5; and 10-year survivals (32% and 23%) in the clinical stage II (i.e., bad liver function) group (P < 0.0001). Patients with good liver function in stage II are expected to have better survival and are considered to be the most suitable for HR.

Hepatocellular carcinoma: comparison between liver transplantation, resective surgery, ethanol injection, and chemoembolization

Abstract Between January 1989 and June 1997, 533 patients (423 male, 110 female, mean age 61 years, range 22–89 years) with hepatocellular carcinoma (HCC) were observed at our center. We report on 419 patients retrospectively compared for different treatments: liver transplantation (LT; 55 patients), resective surgery (RS; 41 patients), transarterial chemoembolization (TACE; 171 patients) and percutaneous ethanol injection (PEI; 152 patients). The 3- and 5-year actuarial survival rates were, respectively, 72% and 68% for LT, 64 and 44% for RS, 54 and 36% for PEI, and 32 and 22% for TACE. Survival curves were compared for sex, age, tumor characteristics, alphafetoprotein level, Child class, and etiology of cirrhosis. All patient-related characteristics examined (sex, age) are not significantly related to patient survival. Tumor-related variables and associated liver disease variables significantly conditioned survival in relation to different treatments. LT seems to be the treatment of choice for monofocal HCC less then 5 cm in diameter and in selected cases of plurifocal HCC.     

不同治疗模式对不能切除的肝癌二期手术预后的影响

目的探讨不能切除的肝细胞癌(HCC)经皮穿刺肝动脉化疗栓塞(TACE)及经手术肝动脉结扎、置管化疗栓塞(HALCE)缩小后二期切除的疗效,并比较不同治疗模式对预后的影响.方法204例HCC二期切除患者,分成TACE组及HALCE组.TACE组112例,行TACE1～7次(中位2.4).HALCE组92例,其中49例行HALCE,7例行HALCE+肝脏外放射治疗,36例行HALCE+导向内放射治疗.肿瘤缩小后予以切除.选择7个可能对HCC二期切除术后预后产生影响的临床因素通过单因素、多因素Cox模型对预后进行分析.结果随访至1999年6月,首次TACE及HALCE后1、3、5、7年生存率分别为95.7%、69.3%、56.5%及44.5%,切除肿瘤后1、3、5、7年生存率分别为88.5%、64.9%、51.9%及38.3%.TACE组及HALCE组1、3、5、7年生存率分别为94.1%、64.7%、51.2%、40.8%和96.3%、73.9%、61.6%、45.2%,2组差异无显著性意义(P＞0.05).影响预后的主要因素是肝硬化程度和肿瘤坏死程度(P＜0.05).TACE组中肝硬化程度、缩小后肿瘤有无包膜及肿瘤坏死程度是影响预后的主要因素(P＜0.05),而HALCE组各因素对预后影响差异无显著性意义(P＞0.05).结论不能一期切除的HCC缩小后应进行二期切除,且可获得满意疗效.而肝硬化程度、肿瘤坏死程度是影响肝癌二期切除预后的主要因素.     

Clinical management of recurrent hepatocellular carcinoma.

OBJECTIVE: The aim of this study was to evaluate the long-term benefits of the aggressive treatments with resection or transarterial chemoembolization (TACE) for recurrent hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: Primary HCC is one of the most fatal malignancies in Taiwan. The result of resection for HCC remains unsatisfactory, primarily due to the high recurrence rate. To improve surgical results, recurrent HCC must be treated with aggressive resection or TACE. METHODS: The authors evaluated the results of repeated hepatic resection among 25 patients with recurrent HCC and of TACE among 12 patients with resectable recurrent HCC. The outcomes of an additional 64 patients with unresectable recurrent HCC were also evaluated. RESULTS: During the follow-up period from 2-112 months, 52% (13/25) of patients receiving repeat resection (group 1) were alive, whereas 42% (5/12) of patients receiving TACE (group 2) were alive. No perioperative deaths within 30 days after surgery occurred in the repeated resection group. The cumulative survival rates at 1, 2, 3, and 5 years after the first operation were 92%, 84%, 71.6%, and 65.1% in group 1 and 83.3%, 75%, 75%, and 22.5% in group 2. The survival rates at 6 months and at 1, 2, and 3 years after recurrence were 92%, 72%, 64%, and 44.8% in group 1 and 83.3%, 75%, 66.7%, and 48% in group 2. The survival of patients with unresectable recurrent HCC was much worse: 1-, 2-, 3-, and 5-year survival after surgery was 57.8%, 29.8%, 15.5%, and 0%; and 6-month and 1-, 2-, and 3-year survival after recurrence was 46.5%, 29.2%, 12.5% and 7.8%. CONCLUSIONS: More aggressive treatment with repeated hepatic resection can prolong survival time after recurrence of HCC in selected patients. However, TACE can also achieve good results although it is not thought of as curative.     

Prognosis of hepatocellular carcinoma associated with Child class B and C cirrhosis in relation to treatment: a multivariate analysis of 411 patients at a single center

Background/Purpose: Given that the prognosis of patients with hepatocellular carcinoma (HCC) complicating severe cirrhosis remains uncertain, particularly with regard to various therapeutic strategies, we have evaluated the prognosis in a series of patients with homogeneous diagnostic and therapeutic histories. Methods: From 1990 to 1998, 411 consecutive HCC patients associated with Child class B and class C cirrhosis who did not have lymph node or distant metastasis were treated by partial hepatectomy (PH; n = 48), percutaneous ethanol injection (PEI; n = 105), transcatheter arterial chemoembolization (TACE; n = 189), chemotherapy, or supportive care (chemo/supportive; n = 69). Univariate survival curves were estimated. The Cox model, stratified by the treatment groups, was used for multivariate analysis. Results: As of January 1999, 305 patients (74.2%) had died. Overall median survival was 23.4 months. There were statistically significant differences between the survival times of patients receiving PH or PEI and TACE, as compared with those receiving chemo/supportive care. According to multivariate analysis, the independent predictive survival factors were: albumin level (≥3.0 g/dl), esophageal varices (i.e., absence), tumor size (≤3.0 cm), tumor number (solitary), and α-fetoprotein (AFP) level (<400 ng/ml). According to the total number of risk factors and the median survival, all patients were divided into four subgroups. For the score 0 group (no risk factor group), 3- and 5-year survival rates were 83.1% and 68.0% for PH, and 87.5% and 62.3% for PEI, respectively. In the score 1–2 group (one or two risk factors), survival rates at 3 and 5 years were 53.1% and 40.3% for PH, 54.8% and 33.2% for PEI, and 35.4% and 22.8% for TACE, respectively. For patients with a score of 3 or more, there were no differences among the treatment groups, excluding those with chemo/supportive care. Conclusions: These findings indicate that, in HCC patients with complicating Child B and C cirrhosis, PEI and PH should be considered first for subgroups of patients with scores (risk factors) of 0–2, as an acceptable survival rate was obtained in such patients. Therefore, the advantages and disadvantages of these therapies regarding tumor size and location should be counterbalanced. In patients with a score of 3 or more, TACE, when possible, could be a first choice because of its applicability and its adjuvant nature with respect to other therapies such as liver transplantation.

Survival analysis of transarterial radioembolization with yttrium-90 for hepatocellular carcinoma patients with HBV infection

Introduction

For patients with resectable hepatocellular carcinoma (HCC), hepatectomy remains one of the best treatment options to provide long-term survival. However, more than 50% of the patients have unresectable disease upon diagnosis even though there are no distant metastases. Transarterial chemoembolization (TACE) is a well-established treatment option that offers a palliative survival benefit for this group of patients. A better treatment for unresectable HCC has been sought after. There is some evidence that transarterial radioembolization (TARE) with the agent yttrium-90 produces encouraging outcomes, especially in patients with portal vein tumor thrombus. This study aims to analyze the outcomes of TARE at our center.

Methods

From August 2009 to April 2013, 16 patients underwent TARE at our center. Sixteen patients with similar tumor characteristics were selected to undergo TACE alone for comparison. A retrospective analysis of the prospectively collected data of the patients was conducted. Only patients with newly diagnosed primary tumors were included in this study.

Results

The median survival for patients having TARE was 19.9 versus 14.0 months in the TACE group (P=0.615). There was no difference in terms of tumor response according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST) (P=0.632). The 1-, 2- and 3-year survival rates in the TARE group were 80.0%, 30.5% and 20.3% respectively. The 1-year survival in the TACE group was 58.3% (P=0.615). For patients who had major vascular invasion (eight in each group), the 1- and 2-year survival rates in the TARE group were 62.5% and 15.6% respectively, while the 1-year survival in the TACE group was 35.0% (P=0.664).

Conclusions

The two groups showed similar results in terms of tumor response and overall survival benefit. TARE might provide a survival benefit for patients with major vessel invasion.

目的本研究旨在评价肝动脉化疗栓塞术后经皮无水乙醇注射术补充治疗对原发性肝细胞癌（HCC）疾病进程和总生存期的影响。方法全部73例HCC，临床分期均为中国分期Ⅱ期，并接受至少2次肝动脉栓塞化疗。治疗组22例，于肝动脉栓塞化疗（TACE）后补充经皮无水乙醇消融术（PEI），对照组51例TACE后未予补充治疗，比较两组疾病进展时间与生存期差异，并作预后因素分析。结果治疗组与对照组中位疾病进展时间分别为10个月（95％可信区间7．9，12．1）和6个月（95％可信区间4．7，7．3）。治疗组3个月、6个月、1年无进展生存率为77．30％、63．61％、48．12％，对照组3个月、6个月、1年无疾病进展率为76．51％、42．17％、24．82％，两组有显著差别（10g—rank检验，P〈O．05）。两组中位生存期分别为17个月（95%可信区间11，23）、12个月（95％可信区间10，14），总生存期无显著差异（P〉0．05）。结论TACE术后补充PEI能明显延长HCC无进展生存期。     

Role of mesohepatectomy with or without transcatheter arterial chemoembolization for large centrally located hepatocellular carcinoma

BACKGROUND: The role of preoperative transcatheter arterial chemoembolization (TACE) for resectable hepatocellular carcinoma (HCC) was controversial. METHODS: 246 patients with large centrally located HCC underwent mesohepatectomy (MH) and were divided into two groups: group A, 89 patients with preoperative TACE; group B, 157 patients without preoperative TACE. The aim was to evaluate the influence of preoperative TACE on postoperative complications and long-term results of patients with large centrally located HCC. RESULTS: In the 89 patients of the TACE-MH group, a total of 123 (mean 1.4 per patient) preoperative TACEs were performed. The differences in postoperative complications (34.8 vs. 24.2%; p=0.075) and overall hospital mortality (3.4 vs. 0.6%; p=0.103) between the two groups were not significant. The postoperative recurrence rate in the remnant liver was higher in the MH group than in the TACE-MH group (79.6 vs. 73.0%), while the extrahepatic metastasis rate in the TACE-MH group was higher than that in the MH group (11.1 vs. 7.0%). Overall 1-, 3-, and 5-year survival rates were 87.1, 62.9, and 46.2%, respectively, for the TACE-MH group, and 82.2, 54.4, and 31.7%, respectively, for the MH group (p=0.001); 1-, 3-, and 5-year disease-free survival rates were 75.0, 46.2, and 31.8%, respectively, for the TACE-MH group, and 69.6, 38.0, and 16.5%, respectively, for the MH group (p=0.002). CONCLUSIONS: Long-term outcomes of patients with preoperative TACE were improved and the pattern of the recurrences after surgery was altered. The patients with large centrally located HCC could benefit more from this neoadjuvant treatment, although there was some influence of preoperative TACE on postoperative complications.

目的：探讨原发性肝癌（HCC）合并门静脉癌栓（PVTT）的外科治疗及疗效。方法：回顾性分析2010年1月—2013年1月收治的68例HCC合并PVTT患者临床资料,其中50例行手术（规则半肝+癌栓及受累门静脉切除术或不规则肝切除+门脉癌栓取出术）+经导管肝动脉化疗栓塞术（TACE）治疗（联合治疗组）;18例患者单纯口服索拉非尼治疗（索拉非尼治疗组）。联合治疗组患者中,11例PVTT侵犯门静脉二级及以上分支,39例侵犯门静脉一级分支;索拉非尼治疗组患者PVTT侵犯部位均为门静脉一级分支。分析患者0.5、1、2、3年生存率、总生存时间（OS）、疾病进展时间（TTP）。结果：联合治疗组PVTT侵犯门静脉二级及以上分支患者与侵犯门静脉一级分支患者0.5、1、2、3年生存率分别为100%、90.9%、18.2%、9.1%与87.2%、51.3%、15.4%、5.1%;索拉非尼治疗组0.5、1、2、3年生存率分别为83.3%、33.3%、0%、0%。联合治疗组PVTT侵犯门静脉二级及以上分支患者与侵犯门静脉一级分支患者中位OS为16个月与12个月,中位TTP为7个月与5个月;索拉非尼治疗组中位OS为9个月,中位TTP为4个月。统计学分析显示,联合治疗组无论是PVTT侵犯门静脉二级及以上分支或侵犯门静脉一级分支患者中位OS及中位TTP均明显长于索拉非尼治疗组（均P<0.05）。结论：对于合并门静脉一级及以上分支癌栓的晚期HCC患者,可行外科手术联合术后TACE治疗,且疗效优于单纯索拉非尼治疗。

     

TACE联合PEI治疗原发性肝癌血液循环性肝癌细胞的变化及意义

目的：探讨联合经肝动脉化疗栓塞术(TACE)及B超引导下肿瘤局部无水酒精注射术(PEI),治疗原发性肝癌周围静脉血液循环性肝癌细胞的变化及其意义.方法:应用巢式RT-PCR检测12例原发性肝癌患者血液循环性肝癌细胞,并经TACE及PEI联合治疗,观察其血液循环性肝癌细胞的变化.结果:血液循环性肝癌细胞表达阳性的5例原发性肝癌患者(41.67%),经TACE及PEI联合治疗后,其血液循环性肝癌细胞均转为阴性(100%,P<0.01).结论:联合TACE及PEI治疗原发性肝癌可有效地杀灭血液中播散的循环性肝癌细胞,可预防肝癌的复发和转移.     

Is transarterial chemoembolization necessary before liver transplantation for hepatocellular carcinoma?

BACKGROUND: Transarterial chemoembolization (TACE) before liver transplantation (LT) for hepatocellular carcinoma (HCC) has been proposed to prevent tumor progression, thus decreasing tumor recurrence and increasing survival. METHODS: We studied 46 patients undergoing LT for HCC who were divided in 2 groups--group A with pretransplant TACE (18 patients [39.1%]) and group B without pretransplant TACE (28 patients [60.9%])--and compared postoperative and long-term results between the 2 groups. RESULTS: There were no statistical differences in morbidity, transfusion needles, and postoperative time between-and no acute arterial or portal complication in-the 2 groups. There were no statistical differences in tumor recurrence (16.7 % vs 36.4 %, P=.16) with regard to pathway (mainly extrahepatic) or time. In group A patients, mean survival was 89.3+/-21.7 months with 1-, 3-, and 5-year actuarial survival rates of 83.3%, 60.5%, and 60.5%, respectively. In group B patients, mean survival was 75.1+/-19.1 months with 1-, 3-, and 5-year actuarial survival rates of 77.2%, 58.7%, and 38.1%, respectively. The differences in mean survival were not statistically significant (PX .56), nor was 5-year disease-free survival, which was 54% in group A and 39.5% in group B (P=.8). CONCLUSIONS: TACE is a safe procedure for candidates on the wait list who are scheduled for LT to treat HCC. Although TACE does not correlate with increased intraoperative difficulties or postoperative complications, it does not significantly improve tumor recurrence and survival.
