Active clinical trials for "Carcinoma, Hepatocellular"

The purpose of the investigators' study is to prospectively evaluate whether low-dose thalidomide adjuvant therapy will improve the outcome of radiofrequency ablation for hepatocellular carcinoma (HCC).

The aim of this study is to assess efficacy of the different adjuvant chemotherapy strategies after hepatectomy and thrombectomy for hepatocellular carcinoma (HCC) and portal vein tumor thrombosis( PVTT).

Chemoembolization (TACE) is used in the majority of advanced hepatocellular carcinomas. Randomized clinical trials indicated that TACE improves overall survival in patients with good liver function (Child-pugh A or B). However, the shortcoming of TACE is obvious: hypoxia induced neoangiogenesis after blockage of blood supply of the tumor; repeat TACE deteriorates liver cirrhosis due to toxicity of chemotherapeutic agent to the parenchyma liver. Thalidomide has been reported to have antiangiogenic and antimetastatic effects. The objectives of adjuvant therapy with thalidomide for chemoembolization is to evaluate overall survival and time to progression.

This study will assess the clinical efficacy and safety of fluorouracil implants regional chemotherapy during the surgical treatment for early-stage hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a consequence of liver cirrhosis. In early tumour stages, tumour resection or liver transplantation are therapeutic options; later tumour stages may be treated with locally ablative treatments such as percutaneous ethanol instillation (PEI), transarterial chemoembolization (TACE) or radio-frequency thermoablation. This randomized study investigates the effect of PEI on survival of patients with HCC. All patients will receive hormonal treatment (long-acting somatostatin intramuscularly [i.m.]) and will be randomized for treatment with PEI or no additional treatment.

To evaluate the safety, tolerability and efficacy of autologous γδT cells in the treatment of advanced hepatitis B-related hepatocellular carcinoma.

The presence of portal vein tumor thrombosis (PVTT) in patients with hepatocellular carcinoma (HCC) is one of the most significant prognostic factors for poor prognosis, without treatment, their survival is less than 3 months. In the HCC patients who combined with PVTT, Radiation therapy (RT) showed 50% of local control and about 10 months survival duration. Despite the standard treatment of the HCC combined with PVTT is sorafenib, but Korean Liver Cancer Study Group (KLCSG) recommend RT as an alternative option in those patients. Investigators previously reported the retrospective study that the scheduled interval Trans-catheter Arterial Chemo-embolization (TACE) followed by RT for HCC combined with PVTT and 60% of the patients showed objective response without significant elevation of complication. However, the prospective outcomes of TACE followed by RT for HCC are scantly reported. Based on those background, we start this prospective study to evaluate the clinical outcomes and adverse event in the RT after TACE in the unresectable HCC patients who combined with PVTT.

Study Phase: multi-institutional Phase II study Primary Objective(s): To determine overall survival for HCC patients treated with CyberKnife SBRT at 2 years. Secondary Objective(s): 1) To determine overall survival for HCC patients treated with CyberKnife SBRT at 1 year 2) To determine local control using RECIST and EASL criteria at 1 and 2 years 3) To assess progression-free survival at 1 and 2 years 4) To assess acute and late toxicities following CyberKnife SBRT. Hypothesis: Overall survival rate of HCC patients at one year after SBRT treatment is not less than 65%. Study Design: Single arm study. Patients will undergo a CT scan with and without contrast and MRI scan for radiation treatment planning and target delineation.SBRT will be delivered on the CyberKnife with Synchrony Respiratory Tracking capabilities. The tumor will be tracked with 3 implanted fiducial seeds for targeting. Treatment will be delivered in 3 fractions within a 7 day window at the discretion of the investigator. Sample size: The sample size required is 93 with a power of 90%, p=0.05, 50% response rate is considered not effective (p0) and 65% overall survival rate at 1 year (p1) is considered effectiveness of the treatment. The estimated drop-out rate is 20%, so the total sample size would be 117. Statistical Considerations: The set of Intention-To-Treat (ITT) will be analyzed. All patients will be censored at their last visit, including the patients lost to follow-up. All patients will be followed and counted in the therapy to which they were assigned, even if they decline that therapy. Only those patients who refuse (in writing) to have their outcomes count in the study's conclusions will not be included in the analyses from that time forward; however, the follow-up data for such patients will be included up until the time they withdraw consent. Such patients will be replaced. Baseline characteristics of patients will be presented with summary statistics. Time-to-event survival rates for OS and DFS will be estimated using the Kaplan-Meier method and presented at one and/or two years. The incidence of acute and late toxicities will be presented in tabular form on both a per-patient and per-event basis.

This study is a prospective non-randomized controlled study. The purpose of this study is to evaluate the validity and safety of sorafenib and transcatheter arterial chemoembolization (TACE) for microvascular invasion (MVI) in hepatocellular carcinoma (HCC) patients after radical surgery.

The aim of this study is to confirmed the role of intraoperative controlled release 5-Fluorouracil therapy in the prevention of recurrence after surgery for HCC patients with high risk of preoperative prediction of microvascular invasion.
