Two hundred and eight cirrhotic patients with HCC underwent TACE with a standardized technique. Kaplan-Meier survival rates and 12, 24 at 36 months were 62%, 44% and 25%, respectively. Compared with 407 untreated patients, our series had a longer life expectancy, i.e., from 15 months after treatment on. Life experience was statistically different with the L-R test between the groups selected by Child-Pugh cirrhosis staging (p = 0.00000); all 8 Child-Pugh C patients died within 7 months; a high statistical difference was found between Child-Pugh A and B groups (p = 0.00012). Life experience was statistically different with the L-R test between the four groups selected by tumor size and spread (p = 0.012); statistical significance was not reached between contiguous groups in group vs. group comparisons. The patients with monofocal tumors, regardless of size, survive longer than those with multifocal and infiltrative (p = 0.0010) and those with multifocal (p = 0.0029) lesions. Hazard analysis, according to the stratified Cox model, proved tumor-size and Child-Pugh staging to be prognostic factors (p = 0.00027; p = 0.00000) which exhibit a highly significant correlation with each other (p = 0.00000). With the proportional hazard Cox model, tumor characteristics and Child-Pugh stage resulted to be highly significant independent prognostic factors (p = 0.013 and p = 0.000, respectively). Patient survival rates were graphically plotted against literature rates in 407 untreated patients classified by tumor size and by the Child-Pugh method: the two-year survival rates were higher in the subgroups of patients submitted to TACE. To conclude, TACE is an effective treatment not only for multifocal HCCs, but also for large monofocal and infiltrative HCCs. In contrast, TACE is quite useless in the patients with Child-Pugh C cirrhosis.

Liver cirrhosis with hypersplenism is often associated with HCC. In many such cases, chemoembolization (TACE) may be very difficult because of the high incidence of hemorrhagic complications due to treatment and/or following portal hypertension, as well as for poor hematologic tolerance to antiblastic drugs in cirrhotic patients. Six patients with nodular HCC and cirrhosis (Child B) with hypersplenism were treated by combined TACE and partial splenic embolization (PSE) to reduce splenic size and to improve hematologic and hepatic function rates. Actual and long-lasting (up to 6 months since TACE/PSE) positive results were observed in splenic size and in hepatic function synthesis, as well as on hematologic and hemocoagulation factors. The clinical-laboratory improvement following TACE/PSE allowed TACE to be completed in all cases, following the usual protocol based on 3 procedures. Therefore, in the patients with advanced/decompensated cirrhosis and hypersplenism associated with HCC, the combined one-step TACE/PSE treatment can be said to improve patients' tolerance to antiblastic drugs and to reduce the risk of hemorrhagic complications due to invasive radiologic procedures and/or to portal hypertension.

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.

We performed a clinical evaluation on the antiemetic profile and the plasma concentration of Azasetron Hydrochloride (a new selective 5-HT3 receptor antagonist), in transcatheter arterial chemoembolization using CDDP for unresectable hepatocellular carcinoma. Antiemetic effects were examined in 32 patients in the serotone group (administration of serotone 10 mg + methylprednisolone 125 mg) and in 77 patients of the control group (administration of metoclopramide 20-30 mg + methylprednisolone 500 mg). The response rate and the CR ratio in serotone group was 97% and 66%, respectively. These results were statistically higher than in the control group. Although all patients had chronic liver diseases, no side effects and complications related to administration of serotone were observed. The average area under the concentration (AUC) curve of plasma serotone in five patients with liver cirrhosis was 531 ng.h/ml, which was greater than that of a healthy volunteer. In conclusion, serotone is a new, safe and useful antiemetic drug in TACE therapy for hepatocellular carcinoma.

The selection of an appropriate treatment strategy for patients with HCC depends on careful tumor staging and assessment of the underlying liver disease (Fig. 5). All patients with localized HCC (involvement of one single lobe, no vascular invasion or extrahepatic disease) should be evaluated for the potentially curative therapeutic options of partial hepatectomy or OLT. Candidates for partial hepatectomy must have no liver disease or Child's A cirrhosis, normal portal pressure, and normal serum bilirubin. For patients not meeting these criteria, OLT should be considered if there is a solitary lesion smaller than 5 cm in diameter or fewer than three lesions smaller than 3 cm. Local ablative therapies such as PEI, RFA, and TACE offer palliation for patients for whom surgical approaches are contraindicated. Percutaneous alcohol injection and RFA are minimally invasive and can be used on an outpatient basis, usually for tumor nodules smaller than 3 cm. When these therapies are used for small tumors, the survival rates can be similar to those achieved by partial hepatectomy. Transcatheter [figure: see text] arterial chemoembolization may be used as an interim treatment for patients waiting for OLT. Although TACE is often used for the palliation of large tumors, significant survival benefits have not yet been demonstrated for this indication.

Liver transplantation (LT) for malignant tumors should be accepted if, with adequate case selection, long-term results are similar to those in patients transplanted for benign diseases. The aim of the present study was to reexamine selection criteria for LT in malignant diseases with particular emphasis on hepatocellular carcinoma (HCC) in cirrhosis. One hundred-three of 369 patients transplanted in our unit had HCC in cirrhosis (28%), 15 of which were incidental tumors, and 234 patients underwent LT for non-cholestatic cirrhosis. Pretransplant arterial chemoembolization(TACE) was performed in 36 cases (41%) of known HCC. Only early,well-delimited tumors in advanced cirrhosis with no extrahepatic disease were accepted for LT. Hepatocellular carcinoma characteristics included mean tumor size (3.1 cm), multiple (59%), bilobular involvement (31%), and vascular invasion (9.2%). Postoperative mortality was 4%. Median follow-up was 67.5 months. Tumor recurrence rate was 14.5%, 33% (5/15) in incidental tumors and 11.4% (10/88) in known HCC and by tumor stage (pTNM): 7.7% (1/13) in stage I, 16.7%(5/30) in stage II, 15% (3/20) in stage III, and 17% (6/35) in stage IV. Mean time for recurrence was 20.6 months. Tumoral vascular invasion, tumor differentiation, and satellite tumors were significant factors for tumor recurrence in univariate analysis, whereas tumor vascular invasion was the only significant factor for tumor recurrence in multivariate analysis. Actuarial survival rates at 1, 3, and 5 years were 81%, 66%, 58%, respectively, in patients with HCC and were similar to those of cirrhotic patients 76%, 67%, 63%, respectively. In conclusion, patients with early HCC in cirrhosis are good candidates for LT; results are similar when compared with those of cirrhotic patients without tumor. Liver transplantation for other malignancies is admitted only in fibrolamellar hepatoma, hepatoblastoma, epithelioid hemangioendothelioma without extrahepatic disease, and in metastases from carcinoid tumors.

Hepatocellular carcinoma (HCC) is one of the most common cancers and is the leading cause of cancer death in Taiwan. Curative surgery is feasible for only about 30% of patients. Transarterial embolization or chemoembolization (TAE/TACE) has been demonstrated to provide a survival benefit compared with supportive care for HCC patients with adequate liver reserves, tumors confined to the liver, and no evidence of portal vein thrombosis. Percutaneous ethanol injection (PEI) may provide long-term disease control if the extent of liver tumors is limited (3 or less in number and less than 3 cm in diameter). The relative efficacy of TAE/TACE, PEI, and other locoregional treatment modalities, such as radiofrequency ablation or cryosurgery, remains unclear. Radiotherapy has been used mostly as a salvage therapy in combination with other locoregional modalities. Despite the incorporation of 3-dimensional conformal technology, radiation-induced liver injury remains an important problem, especially for patients with hepatitis B-related cirrhosis. Systemic therapy is difficult for HCC because of the underlying cirrhosis and accompanying hypersplenism and peripheral cytopenia. HCC is typically resistant to most cytotoxic agents. Biochemical modulation with high-dose tamoxifen may sensitize HCC cells to doxorubicin-induced apoptosis and improve the clinical response to doxorubicin in patients with advanced HCC. Thalidomide, which inhibits angiogenesis induced by vascular endothelial growth factor and basic fibroblast growth factor, can produce a response in some HCC patients. Future research on drug therapy for HCC will focus on identification of tumor-specific targets.

Treatment of the liver cancer (LC) patient is often problematic as the tumour is identified at an advanced stage: the frequent coexistence of cirrhosis limits the use of surgical resection, there is no efficacious chemotherapy, and in patients treatable with liver transplant, indication is rendered uncertain from the point of view of cost-effectiveness and the high risk of recurrence of the tumour and hepatitis infection. Surgical resection appears to be the treatment of choice in patients with a liver tumour in a ''healthy'' liver. Instead, orthotopic liver transplant is the most valid indication for patients with cirrhosis and tumours of dimensions smaller than 2-3 cm. Nevertheless, due to the lack of organs palliative treatments, like surgical resection, PEI and TACE are the most indicated in patients with advanced neoplastic disease, in practice patients with TNM III and IV; radiotherapy with protons and the coagulation of the tumour by microwaves or laser fibres are also used in the attempt to slow down the progress of the neoplastic process. These methods may increase the possibility of cure in well chosen patients. In some patients the most effective approach may be the combined use of various therapies, such as TACE, PEI and surgery.

The purpose of this study was to evaluate the long-term results with monotherapy for hepatocellular carcinoma (HCC) in the setting of cirrhosis. We reviewed data of 14 patients who survived for at least 5 years after performance of liver resection (n = 1), transarterial chemoembolization (TACE, n = 3), or liver transplantation (OLT, n = 19). Eight patients were within the Milan criteria, whereas the remaining 6 were beyond the criteria. Tumor stages according to the UICC were I (n = 8), II (n = 5), and IIIA (n = 1). Vascular invasion was not detected in any patient. The HCCs recurred in 2 patients, at 81 and 48 months' posttransplant. Sites of recurrence were the intrathoracic lymph nodes in the first case, and lungs in the second case. Treatment of recurrence included chemotherapy in the first case and local resection in the second case. Both patients died at 98 and 64 months postoperation (ie, 17 and 16 months, respectively, after the diagnosis of the recurrence). A third patient died of nontumor-related causes at 69 months after his first TACE. Currently, 11 patients are alive with a median survival of 70 months (range, 63-144 months). The alpha-fetoprotein level was demonstrated to be prognostic of recurrence by discriminant function analysis. In conclusion, OLT provided the best long-term results as monotherapy for HCC in the setting of cirrhosis.

Hepatocellular carcinoma (HCC) is a malignant tumor which is becoming more prevalent worldwide. Patients at high risk of developing HCC, namely hepatitis B- and C-related liver cirrhosis patients, should be entered into surveillance programs, which should be performed using both ultrasonography and 3 tumor markers (AFP, PIVKA-II, AFP-L3). The surveillance interval needs to be shortened for patients at higher risk of HCC. Therefore, super-high-risk patients should be screened at 3- to 4-month intervals based on their risk of developing HCC. Sonazoid-enhanced US is extremely useful to characterize hepatic tumors when compared with multidetector-row computed tomography (MDCT). Moreover, Sonazoid-enhanced US with defect reperfusion imaging is a breakthrough approach in the treatment of HCC. This technique will markedly change the therapeutic strategy for liver cancer. Furthermore, diagnostic capability using the new imaging technique Gd-EOB-DTPA MRI is promising. A reduced uptake (low intensity) in the hepatobiliary phase of Gd-EOB-DTPA MRI strongly suggests HCC (including early-stage HCC) or a high-grade dysplastic nodule with high malignant potential. Empirically, intrahepatic arterial infusion chemotherapy using implanted reservoir port is known to be effective for advanced HCC with vascular invasion; however, no randomized study exists to prove its efficacy. Further controlled study is necessary to establish this treatment option as a standard of care in a treatment algorithm for HCC. In contrast, sorafenib was established as the first choice of treatment as a standard of care in advanced HCC patients with preserved liver function and vascular invasion/extrahepatic spread. Furthermore, global clinical trials are now ongoing using sorafenib as an adjuvant setting after resection, ablation or TACE. Efficacy of combined use of sorafenib with TACE or intra-arterial infusion chemotherapy is not clear. In order to clarify this issue a randomized clinical trial for intermediate and advanced HCC comparing sorafenib alone versus sorafenib combined with maintenance TACE/intra-arterial infusion chemotherapy and/or intra-arterial infusion chemotherapy is scheduled to be initiated in Japan in 2009. If positive results are obtained by these trials, its impact on treatment strategy for HCC will be drastically changed.
