Active clinical trials for "Carcinoma, Hepatocellular"

The aim of this study is to establish a selection criteria of hepatectomy for patients with multiple hepatocellular carcinomas based on the NDR Scoring System

This multicenter prospective nonrandomized study is to evaluate the efficacy of TACE combined with sorafenib compared with TACE monotherapy in term of overall survival in intermediate-stage HCC.

Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third most frequent cause of cancer death worldwide. Hepatic resection (HR) is the conventional ''curative'' treatment for HCC. In both the European and the United States Proposed Guidelines for HCC, HR is recommended only for patients with preserved liver function and with early stage HCC. Unfortunately, because of tumor multifocality, portal vein invasion, and underlying advanced cirrhosis, only 10% to 30% of HCCs are amenable to such a ''curative'' treatment at the time of diagnosis. Transarterialchemoembolization (TACE) has become the most popular palliative treatment for patients with unresectable HCC, and it is no longer considered as a contraindication to HCC with portal vein tumor thrombus (PVTT). Unfortunately, the long-term outcomes are generally poor for HCC treated with TACE, especially for HCC with PVTT. To improve on the results of treatment of HCC with PVTT, attempts have been made to perform HR for these patients. HCC with PVTT remains a contraindication to liver transplantation because of the high rate of tumor recurrence, and because of the severe shortage of donor organs. HR remains the only therapeutic option that may still offer a chance of cure. With advances in surgical techniques, it has become feasible to remove all gross tumors, including PVTT, which has extended to the main portal vein, safely by surgery. More HCC with PVTT, which previously were considered as unresectable, have become resectable.Recent studies have even shown favorable long-term survival outcomes of HR in well-selected cases of HCC with PVTT. However, the recurrence rate after HR for PVTT is still high and the prognosis for patients with HCC with PVTT is very poor. Systemic chemotherapy is considered to be one of the main treatments for malignant tumors. HCC is known to be highly refractory to conventional systemic chemotherapy because of its heterogeneity and multiple etiologies. Before the advent of the molecular-targeted agent sorafenib, which has subsequently become the standard of care, no standard systemic drug or treatment regimen had shown an obvious survival benefit in HCC. Nowadays, there is no systemic chemotherapy regimen had been definitively recommended as the standard for treating HCC. Clinical activity of several regimens containing oxaliplatin (OXA) in advanced HCC had been demonstrated in phase II studies. In a phase II study of the FOLFOX4 (infusional fluorouracil [FU], leucovorin[LV], and OXA) regimen in Chinese patients with HCC, median overall survival (OS) was 12.4 months, mean time to progression was 2.0 months, and the response rate (RR) was 18.2%. The safety profile was acceptable. Recently, the results of a phase Ⅲ randomize study showed that FOLFOX4 served as palliative chemotherapy can induce higher overall survival, progression-free survival and response rate comparing to doxorubicin in patients with advanced hepatocellular carcinoma from Asia. The safety data was also acceptable.So the investigators' hypothesis is that post-surgery FOLFOX4 can reduce high recurrence rate after HR for HCC with PVTT. The aim of this open-label, single prospective study is to evaluate the efficacy and safety of HR combined with FOLFOX4 systemic chemotherapy for patients with HCC with PVTT.

The purpose of this study is to evaluate the efficacy of Dendritic and Cytokine-induced Killer Cells (DC-CIK) for hepatocellular carcinoma (HCC).

In India, majority of our patients have advanced hepatocellular carcinoma (HCC) at presentation and hence are unsuitable for the available curative treatment options. In such patients the treatment options are mainly palliative. Transarterial chemoembolization (TACE), transarterial chemotherapy (TAC) and various forms of oral chemotherapy are the only available options currently. Many patients have more advanced disease with the involvement of branches of portal vein. This further limits the therapeutic options. According to Barcelona Clinic Liver Cancer (BCLC) staging, involvement of portal vein precludes any standard form of therapy. TAC and oral chemotherapy has been tried in this group of patients by few researchers. Which treatment (TAC or oral chemotherapy) would be better suitable for advanced stage (BCLC C) needs to be explored. However, there are no randomized controlled trials (RCT's) available. TAC is the procedure for treating patients of HCC with portal vein invasion where only the chemotherapeutic drugs are injected into the feeding vessels of the tumor with no subsequent embolization of the feeding vessels. In order to select a modality which would produce better outcomes in advanced HCC patients (BCLC C), this study was planned.

Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world. Partial hepatectomy and liver transplantation are considered to be standard curative therapies for HCC. When surgery is not possible, percutaneous ablation is usually considered to be alternative treatments for HCC. Recurrence is the most frequent serious adverse event observed during the follow-up of HCC patients treated for cure. Repeat hepatectomy is an effective treatment for HCC recurrence, with a 5-year survival rate of 19.4 to 56%. Unfortunately, repeat hepatectomy can be performed only in a small proportion of patients with HCC recurrence (10.4 to 31%), either because of the poor functional liver reserve or because of widespread recurrence. Radiofrequency ablation has been considered to be one of the most effective percutaneous ablations for early-stage HCC in patients with or without surgical prospects. Studies using RFA to treat HCC recurrence after hepatectomy have reported a 3-year survival rate of 62% to 68%, which is comparable to those achieved by surgery. RFA is particularly suitable to treat HCC recurrence after hepatectomy because these tumors are usually detected when they are small, and because RFA causes the least deterioration of liver function in the patients. However, according to our previous study, investigators found the recurrent rate after RFA was higher than 60%. Systemic chemotherapy is considered to be one of the main treatments for malignant tumors. HCC is known to be highly refractory to conventional systemic chemotherapy because of its heterogeneity and multiple etiologies. Before the advent of the molecular-targeted agent sorafenib, which has subsequently become the standard of care, no standard systemic drug or treatment regimen had shown an obvious survival benefit in HCC. Nowadays, there is no systemic chemotherapy regimen had been definitively recommended as the standard for treating HCC. Clinical activity of several regimens containing oxaliplatin (OXA) in advanced HCC had been demonstrated in phase II studies. In a phase II study of the FOLFOX4 (infusional fluorouracil [FU], leucovorin[LV], and OXA) regimen in Chinese patients with HCC, median overall survival (OS) was 12.4 months, mean time to progression was 2.0 months, and the response rate (RR) was 18.2%. The safety profile was acceptable. Recently, the results of a phase Ⅲ randomize study showed that FOLFOX4 served as palliative chemotherapy can induce higher overall survival, progression-free survival and response rate comparing to doxorubicin in patients with advanced hepatocellular carcinoma from Asia. The safety data was also acceptable. Therefore, investigators considered RFA to be an effective treatment for HCC recurrence after curative treatment. So our hypothesis is that RFA combined with FOLFOX4 can reduce high recurrence rate after RFA for recurrent HCC after hepatectomy. The aim of this open-lable, single prospective study is to evaluate the efficacy and safety of RFA combined with FOLFOX4 systemic chemotherapy for recurrent HCC after partial hepatectomy.

Currently，the "ALPPS" (associating liver partition with portal vein ligation for staged hepatectomy) procedure which enables the rapid growth of the future liver remnant and extends surgical indication to patients with mid-advanced stage hepatocellular carcinoma becomes a research hot spot. However, the procedure has a high morbidity and mortality rate.Using radio-frequency ablation instead of in-situ split of liver to avoid forming a coagulation band in stage I will reduce the incidence of complications（bile leakage, abdominal infection,hemorrhage e.t.) The investigators named this technique as Radio-frequency Assisted Liver Partition with Portal vein ligation for staged hepatectomy （RALPPS）.Investigators hypothesized that the RALPPS might result in lower morbidity and mortality rate than ALPPS in the treatment of hepatocellular carcinoma . This Prospective Randomized Controlled Trial is on the Safety and Efficacy of radio-frequency assisted liver partition with portal vein ligation for staged hepatectomy for hepatocellular carcinoma.

The purpose of this study is to determine whether combined radiofrequency ablation and transcatheter chemoembolization (TACE) result in better survival outcomes than TACE alone in patients with HCC and portal vein tumor thrombus.

Hepatocellular carcinoma (HCC) is one of the most commonly malignant tumors around the world and causes death of about 600000~1000000 people each year. Since 1990s, hepatic carcinoma has become the second carcinoma killer in China. Surgical resection or liver transplantation is the only method possibly able to cure hepatic carcinoma. However, due to multiple tumors or poor hepatic function reserve in cirrhosis, surgical treatment is suitable for only a small portion of patients (11.9%-30.1%). Therefore, in clinical practice, transarterial chemoembolization (TACE) or transarterial embolization (TAE) is a preferential and standard treatment of unresectable advanced hepatic carcinoma and has notable advantages in controlling local tumors of the liver. Hepatic arterial infusion of oxaliplatin after TACE can significantly increase the local doses of chemotherapeutic agents in the liver, kill micrometastases and residual foci after embolization and demonstrate outstanding efficacy for treating concomitant portal and hepatic vein tumor thrombi. S-1 is a chemotherapeutic agent with convenient use and definite efficacy and, when used concomitantly with TACE, theoretically can not only effectively control intrahepatic foci but also prevent and control extrahepatic metastatic foci. However, this hasn't been verified in clinical application. This study is intended to investigate efficacy and safety of the combination treatment so as to provide a more effective and safety way for treating patients with advanced hepatic carcinoma (Barcelona stage-C patients with concomitant portal vein tumor thrombi or extrahepatic metastasis).

The purpose of the study is to determine whether transarterial chemoembolization containing arsenic trioxide is safe and effective in the treatment of intermediate-stage hepatocellular carcinoma.
