Treatment of hepatocellular carcinoma and the exacerbation of liver function.

We performed interventional treatments on 50 patients with hepatocellular carcinoma (HCC) and analyzed the relationship between these treatments and the exacerbation of liver function after treatment. The different treatments included transcatheter arterial embolization (TAE), percutaneous ethanol injection therapy (PEIT), selective segmental sclerotherapy (SSS), combined TAE and PEIT, or transcatheter arterial chemo-injection (TAI). Thirteen patients showed an exacerbation of liver function after treatment. The laboratory data on admission, showed the lower levels of serum albumin and cholinesterase in this group. In comparison to patients who did not show any exacerbation of liver function, these 13 patients had undergone combined TAE and PEIT. An analysis of cases after TAE and PEIT treatment revealed that the time from TAE to PEIT was shorter in the exacerbation group than in the non-exacerbation group, however, there was no significant difference in the amount of injected ethanol between the two groups. It is assumed that the values of albumin and cholinesterase before treatment, or the period from TAE to PEIT are related to liver failure after treatment. Combining TAE and PEIT treatment may be effective for HCC, however, we should pay special attention to liver failure after treatment.     

Three Treatment Methods via the Hepatic Artery for Hepatocellular Carcinoma - A Retrospective Study

Background: To evaluate the relative effectiveness of different treatments of hepatocellular carcinoma(HCC) via the hepatic artery. Materials and Methods: The study sample group consisted of 418 patients whowere randomly selected from 2008 to 2012 with a first diagnosis of HCC and treated with transcatheter arterialchemoembolization (TACE) or without (TAE) chemotherapy or transcatheter arterial infusion (TAI). Wecollected data including tumor size preoperative and one month thereafter to compare change in areas acrossthe three groups, along with various laboratory indexes for comparison. Results: The overall average change ofareas was 240.8±72.1 mm2. In the three groups it was 265.0±58.0 mm2 vs. 250.5±51.9 mm2 vs. 123.7±26.2 mm2. Ingroups TACE and TAE values were larger than in group TAI (p<0.01), but the difference between the two wasnot statistically significant (p= 0.191). Additionally, U/L change of aspartate aminotransferase (AST) and alanineaminotransferase (ALT) in groups TACE and TAE was greater than in the TAI cases (24.0±13.5 vs. 20.9±12.1 vs.5.47±8.20 and 25.6±13.5 vs.23.2±12.28 vs.5.48±14.3) on the preoperative day and two days thereafter (p<0.01).Between the two groups there was no significant cariation (p= 0.320 and p= 0.609). However, the AST and ALTrecovered to normal levels one month later on therapy with liver protecting drugs. Conclusion: The groupsTACE and TAE demonstrated more effective reduction of tumor size than group TAI. While lipiodol causedacute liver function damage, this proved reversible.

Significance of reduction surgery in multidisciplinary treatment of advanced hepatocellular carcinoma with multiple intrahepatic lesions

BACKGROUND AND OBJECTIVES: By comparing the survival rates of patients treated with or without surgery, the significance of, and the indication for, reduction surgery in the multidisciplinary treatment of patients with HCC with multiple intrahepatic lesions were examined. METHODS: In patients with HCC with multiple intrahepatic lesions, cumulative survival rates were determined and compared for 28 patients (group S) who underwent reductive hepatic resection and 43 (group N) who were treated nonsurgically by transcatheter arterial infusion chemotherapy (TAI), transcatheter arterial chemoembolization (TACE), or percutaneous transhepatic ethanol injection therapy. In group S, 20 patients had adjuvant therapy, consisting of ethanol injection therapy or microwave coagulonecrotic therapy for the remaining satellite lesions during hepatectomy, and all patients in this group underwent TAI or TACE postoperatively. The influence of surgery on patient survival was examined by multiple regression analysis using the Cox's hazard model; then, for each prognostic factor, survival rates were obtained and compared between the groups. RESULTS: In group S, the 1-, 3-, and 5-year cumulative survival rates were 58.2%, 27.1%, and 21.7%, whereas the corresponding values in group N were 34.3%, 4.7%, and 4.7%, the difference being statistically significant (P = 0.0239). In group S, the 1-, 3-, and 5-year cumulative survival rates for patients without intraoperative adjuvant therapy were 25%, 0%, and 0%, whereas those for patients with intraoperative adjuvant therapy were 72.7%, 41.3%, and 33.0% (P = 0.001). Multiple regression analysis showed that hepatic resection, the Child-Pugh score, and the size of the main tumor affected survival independently. Univariate analysis of differences in the cumulative survival rates between the groups as a function of prognostic factor showed that group S had statistically significant better survival rates than group N in those subgroups of patients who were <60 years old, with HBV infection, with a Child-Pugh score of 5 or 6, with a main tumor of <5-cm diameter, with <5 tumors, or without portal thrombi. CONCLUSIONS: When combined with intraoperative adjuvant therapy for remaining satellite tumors, reduction surgery provided survival benefit for patients with HCC with multiple intrahepatic lesions in those groups of patients selected by criteria determined in this study.     

原发性肝癌综合介入治疗的疗效分析

目的探讨原发性肝癌综合介入治疗的疗效。方法回顾性分析1126例原发性肝癌患者手术前后行经导管肝动脉化疗栓塞术(TACE)、TACE后射频消融(RFA)治疗、TACE或经导管肝动脉化疗灌注治疗(TAI)后辅以中药和生物治疗的临床资料,分析患者肝功能、肿瘤标志物、癌灶影像资料和生存率等,比较各种综合介入治疗的价值。结果全组患者1、3、5年生存率分别为67.8%、28.7%和18.8%。其中术前TACE组1、3、5年生存率分别为74.7%、41.4%和36.9%,术后TACE组1、3、5年生存率分别为78.9%、40.4%和37.5%;TACE RFA组的近期有效率为93.4%,1、3年生存率分别为74.5%和36.8%;TACE组的近期有效率为83.2%,1、3、5年生存率分别为69.3%、21.7%和8.4%;TAI治疗的近期有效率为27.5%,1、3年生存率分别为11.6%和0。TACE RFA组和TACE组间肝功能Child降级、瘤内与瘤周血流信号消失和甲胎蛋白转阴率差异均无统计学意义,TACE RFA组、TACE组与TAI组肝功能Child降级差异无统计学意义。结论原发性肝癌手术切除前后TACE效果最佳,手术前与手术后行TACE疗效相近;TACE RFA疗效优于TACE;TAI疗效较差。     

Radiotherapy for large hepatocellular carcinoma combined with transcatheter arterial embolization and percutaneous ethanol injection therapy.

This study was performed to determine the effect of radiotherapy (RT) combined with transcatheter arterial embolization (TAE) and percutaneous ethanol injection (PEI) on large HCC. Between 1988 and 1996, 102 patients with unresectable, biopsy proven HCC underwent uniform pretreatment assessment followed by TAE and PEI. Of the 102 patients, 68 (67%) had more than 2 lesions in the liver, and the largest tumor sizes in each patient ranged from 3 to 8 cm in diameter. Immediately after TAE and PEI, external beam RT (36 to 70 Gy) was administered to the largest tumors only in 44 patients. The cause-specific 5-year survival rate for all patients was 39.9%. The 3-year survival rate of the RT group was better than that of the no RT group (81.1% vs. 54.6%). The cumulative local control rates of the largest treated tumors were 53.2% in the RT group and 32.7% in the no RT, respectively (p=0.006). When the survival rate was compared between patients with and without local control in the RT group, that of patients with local control was significantly better than that with local recurrences (p=0.048). No deaths or major treatment related complications occurred. RT combined with TAE and PEI did not clearly show improvement of the survival, however, it effectively controlled large HCC, and demonstrated minimal toxicity. This treatment may represent therapeutic option for some patients with unresectable large HCC.     

A Prospective Randomized Trial of the Preventive Effect of Pre-operative Transcatheter Arterial Embolization against Recurrence of Hepatocellular Carcinoma

To clarify whether pre-operalive transcatheter arterial embolization (TAE) improves survival after hepatectomy, a prospective randomized comparative study was done. Of a total of 115 registered patients having solitary hepatocellular carcinoma (HCC) 2 to 5 cm in diameter, 18 (15.7%) were excluded after randomization. As a result, 97 patients were chosen as subjects and divided into two groups: hepatectomy with (group A: n = 50) and without (group B: n=47) pre-operative TAE. The period of observation of the patients who survived the surgery was between 4.0 and 6.6 years. The randomization appeared to have provided well-balanced groups of patients and the clinico-pathological characteristics of the two groups were quite similar. The necrotic part of the cancerous lesions, as confirmed by operative specimens, amounted to 74.8 ±33.4% (mean±SD) in group A and 6.8 ±7.2% in group B (P<0.01). However, the cancer-free survival rates after hepatectomy in both groups showed little difference (39.1±7.0 (%±SE) and 31.1±0.1, respectively). We speculate that TAE is not effective against such HCC accessory lesions as minute intrahepatic metastasis and tumor thrombus and that pre-operative TAE does not improve post-operative survival.     

Effect of repeated transcatheter arterial embolization on the survival time in patients with hepatocellular carcinoma. An analysis by the Cox proportional hazard model.

One hundred fifty-eight patients with hepatocellular carcinoma (HCC) were treated by transcatheter arterial embolization (TAE) as repeatedly as possible. Survival rates at the end of the first, second, and third year were 76.5%, 54.5%, and 41.1%, respectively. In 142 patients with repeated TAE, a significantly increased number of patients with complete necrosis of tumor was observed after repetition of the therapy. Adjusting the imbalance in prognostic factors among patients by using Cox proportional hazard model, it proved that the best response during the repeated therapy, rather than the first response, was significantly associated with survival period of the patients. Aside from the factor of response to the treatment, tumor size was the worst prognostic factor at the time when diagnosis was made. Other significant factors were portal vein invasion by HCC and bilirubin. The survival period of patients with HCC treated by repeated TAE was, therefore, affected by cancer factors, liver cirrhosis factors, and therapy-responsiveness factors. It is concluded that even if complete necrosis of tumor is not obtained after the first trial, repetition of TAE is an effective measure for prolonging of survival time in patients with HCC.

Prognostic factors in patients with hepatocellular carcinoma treated by transcatheter arterial embolization

BACKGROUND: Transcatheter arterial embolization induces marked antitumor response in patients with hepatocellular carcinoma, but the survival benefit of transcatheter arterial embolization remains to be determined. This study investigated prognostic factors in patients with advanced hepatocellular carcinoma treated by transcatheter arterial embolization. METHODS: A total of 128 consecutive patients with non-resectable hepatocellular carcinoma, who had undergone transcatheter arterial embolization between May 1990 and August 1998, were analyzed to investigate prognostic factors. RESULTS: Median survival time and survival proportions at 1, 3 and 5 years were 3.3 years, 92.0, 54.6 and 23.4%, respectively. By multivariate analysis using the accelerated failure time model, age <60 years, hepatitis C virus antibody positivity, serum albumin >3.5 g/dl, absence of portal vein invasion and serum alpha-fetoprotein level <400 ng/ml were significantly associated with favorable survival. For clinical application, we also propose a prognostic equation with combination of specific prognostic factors, by which survival curves of each patient could be predicted directly. CONCLUSION: The findings of the current study may be helpful in predicting the life expectancy of hepatocellular carcinoma patients treated by transcatheter arterial embolization and in designing future clinical trials of transcatheter arterial embolization for hepatocellular carcinoma.     

Transcatheter arterial infusion chemotherapy prior to radiofrequency thermal ablation for single hepatocellular carcinoma reduces the risk of intrahepatic distant recurrence

The aim of the present study was to elucidate the effectiveness of transcatheter arterial infusion chemotherapy (TAI) of the whole liver using an epirubicin-mitomycin-lipiodol emulsion, prior to radiofrequency thermal ablation (RFA), in preventing intrahepatic distant recurrence (IDR) from single hepatocellular carcinoma (HCC). Of the 269 consecutive patients who underwent RFA in our institute for single HCC, a total of 182 patients were analyzed in the present study. The primary endpoint was comparison of the post-RFA IDR-free survival rates in patients treated using TAI with an epirubicin-mitomycin-lipiodol emulsion via the proper hepatic artery (TAI-EML) prior to RFA, and patients that received lipiodol infusion-alone prior to RFA. The secondary endpoints were local tumor progression (LTP) and overall survival (OS). Lipiodol infusion-alone prior to RFA was performed in 88 patients and TAI-EML prior to RFA in 94 patients. The mean tumor size was 2.06 cm (range, 0.9-3.2 cm) in the TAI group and 1.97 cm (range, 0.9-3.3 cm) in the lipiodol-alone group, respectively. The cumulative IDR-free survival rates at 1, 2 and 3 years were 74.0, 50.8 and 34.9%, respectively, in the lipiodol-alone group, and 90.8, 74.8 and 70.0%, respectively, in the TAI group (P<0.001). In terms of the OS, there was a significant difference between these two groups (P=0.048), although there was no significant difference in terms of the LTP (P=0.145). We concluded that TAI-EML prior to RFA appears to be useful in reducing post-RFA IDR and may contribute to improved survival rates.     

超常规剂量碘油超选择TAE与常规TAE后Ⅱ期肝癌切除-27例手术病理及随访研究

目的评价术前应用超常规剂量碘油超选择TAE与常规TAE治疗原发性肝癌的价值。方法1987年8月～1999年12月12年间27例原发性肝癌分为两组治疗组17例,应用常规导管或球囊导管超选择至肿瘤供血动脉,阻断其血流,使注射碘油时不产生逆流,将全部动脉肿瘤血管、病变周围正常的小动脉及肝实质和门静脉分支栓塞,栓后25天～121天手术切除;对照组10例,应用一般导管,常规剂量的碘油超选或不超选栓塞肿瘤供血动脉,栓后20天～140天手术切除。对两组病人切除的标本均进行了详细的病理学研究,同时对全部病人随访3～8年。结果治疗组17例中11例肿瘤100%坏死,其余6例坏死率为85%～95%,3、5年生存率分别为88.2%(15/17)、45.5%(5/11),3例现生存6～8年;对照组10例中2例肿瘤完全坏死,另8例坏死率为75%～95%,3、5年生存率分别为60.0%(6/10)、14.3%(1/7)。结论术前应用超常规剂量碘油超选择TAE治疗原发性肝癌效果明显好于常规TAE。     

Combining transcatheter arterial chemoembolization with percutaneous ethanol injection therapy for small size hepatocellular carcinoma

For patients with unresectable small size HCC, percutaneous ethanol injection therapy (PEIT) is used as a non-surgical treatment because it is difficult to achieve complete tumor necrosis by transcatheter arterial chemoembolization (TAE) alone. However, some small HCCs (<21 mm in diameter) are resistant to PEIT with incomplete tumor necrosis, which is associated with insufficient ethanol injection to the tumor. For more effective treatment for HCC, we performed a combination of TAE and PEIT on patients with small size HCC and evaluated the cumulative recurrence and survival rates. The recurrence rate in patients treated with the combination was less than that of TAE or PEIT alone. There were five patients without tumor recurrence during the follow-up period and three out of these underwent the combination treatment. The period of no recurrence was 33.4 months on average. In conclusion, we recommend combination therapy with TAE and PEIT for patients to accomplish more effective treatment of small size HCC.     

Successful treatment of postoperative multiple hepatic recurrence with hepatic arterial infusion of cisplatin and degrable starch microspheres

A 38-year-old man had multiple recurrence of hepatocellular carcinoma (HCC) with portal vein thrombosis after hepatectomy and postoperative transcatheter arterial chemotherapy with 5-fluorouracil (5-FU). He was treated by trans hepatic arterial embolization (TAE) with 100 mg of cisplatin (CDDP) and degrable starch microspheres (DSM). After 3 courses were administered, the recurrent lesions almost disappeared on CT, and the postoperative rise in PIVKA-II level and AFP level normalized. There were no side effects except slight fever and general fatigue. We recognized a partial response, and the patient is still alive 14 months after hepatectomy. This case suggests that TAE with CDDP and DSM might be useful for prolonging the survival of advanced HCC patients.     

Usefulness of partial splenic embolization (PSE) in hepatocellular carcinomas showing a risk of gastrointestinal bleeding after transcatheter arterial embolization (TAE)

We have examined 103 patients with a hepatocellular carcinoma (HCC) who were treated by transcatheter arterial embolization (TAE) with a partial splenic embolization (PSE) (n = 5) or without a PSE (n = 98). It was found that gastrointestinal (GI) bleeding after TAE occurred in 10 (10.2%) out of the 98 TAE patients and within 10 days after the TAE. In these GI bleeding after TAE patients, the platelet counts were significantly low and marked splenomegaly was seen. It also was found that there was a risk of GI bleeding after TAE in cases showing thrombocytopenia (less than 50,000/microliters) and marked splenomegaly with a splenic index of more than 50. In 5 patients with a high risk of GI bleeding, for whom a PSE was performed, the platelet counts were markedly increased even four weeks after the TAE. The survival rate of TAE patients given a PSE was significantly higher than in TAE patients manifesting a risk of GI bleeding. From these results, it would seem that TAE patients given a PSE is the better therapy for HCC patients manifesting a risk of GI bleeding.

Prognostic factors in the treatment of hepatocellular carcinoma with transcatheter arterial embolization and arterial infusion.

From January 1986 to December 1988, a prospective trial of transcatheter arterial treatment was carried out for hepatocellular carcinoma (HCC). Two hundred seventy-five patients were included. Okuda's staging system was employed. Patients with Stage I and II HCC were treated by transcatheter arterial embolization (TAE) with a gelatin sponge containing an anti-cancer agent (protocol 1a); a gelatin sponge and iodized oil mixed with an anti-cancer agent (protocol 1b); or iodized oil mixed with an anti-cancer agent (protocol 2). Patients with Stage III HCC were treated with iodized oil with anti-cancer agent (protocol 2). As an exception, patients with an unsuccessful superselective catheterization into the proper hepatic artery by Seldinger technique or obstruction of the main trunk of the portal vein were treated with percutaneous transcatheter arterial infusion into the common hepatic artery regardless of stage (protocol 3). Tumor type and extension, area of tumor involvement, portal vein involvement, method of treatment, and presence of ascites and icterus were found to be the significant factors for an initial response to therapy. Treatment method was the most important factor. Respective survival rates at 1 and 2 years were 70.9% and 55.3% for protocol 1a; 62.3% and 43.8% for protocol 1b; 37.8% and 18.3% for protocol 2; and 16.5% and 0% for protocol 3. Many factors proved to significantly influenced prognosis; however, tumor type had the most important prognostic significance followed by AFP value, ascites, treatment protocol, and area of tumor involvement.     

Long-term survival in a patient with hepatocellular carcinoma with resection of a metastatic lymph node after percutaneous ethanol injection therapy

Lymph node (LN) metastases during operation for hepatocellular carcinoma (HCC), but not during operations for other cancer, as many surgeons can attest. We performed partial hepatectomy with LN dissection in a man with LN metstasis from HCC, and long-term survival was achieved. In December 1993, at another hospital, a tumor, 4.2cm in diameter, in this 73-year-old patient had been diagnosed as HCC. Transcatheter arterial embolization (TAE) was performed three times Eighteen months after the operation, a swollen LN was discovered at the hepatic hilum and was treated by TAE once and by transcatheter arterial infusion (TAI) twice. However, the level of alpha-fetoprotein gradually increased and so percutaneous ethanol injection therapy (PEIT) was performed. Nevertheless, serum PIVKA-II (protein induced by vitamin K absence or antagonist II) continued to rise. The patient was referred to our hospital for further treatment. He underwent S5 subsegmentectomy with LN dissection. Histologically, the primary lesion consisted entirely of necrotic tissue. However, in the resected LN, there was residual cancer tissue near its periphery. We concluded that dissection of the affected LN offered the only chance for long-term survival, and that PEIT should be avoided for a metastatic lymph node.
