Active clinical trials for "Carcinoma, Hepatocellular"

350 new cases of hepatocellular carcinoma (HCC) are diagnosed in Denmark each year, but the overall prognosis is poor with a 1-year survival rate of less than 40% and a 5-year survival rate of 10% for the entire patient group. This national phase II non-randomized single-arm study of proton therapy in HCC is conducted with the aim to offer a safe and efficient radiation treatment to fragile patients with reduced dose to the normal liver compared to conventional photon-based radiotherapy.

In this project, the preoperative anatomical location of micro hepatocellular carcinoma under the guidance of CT can provide guidance for accurate surgical resection. It may also shorten the operation time and reduce intraoperative bleeding.

The treatment of HBV related hepatocellular carcinoma has always been a worldwide problem. The aim of this study is to alleviate the progression of hepatitis B related hepatocellular carcinoma by the Chinese medicine "Fu Zheng Jie Du Hua Yu" Principle.

To compare the clinical outcomes of Lenvatinib treatment alone or Lenvatinib + ADI-PEG20 combination treatment in advanced HCC patients with BCLC stage C.

The purpose of this study is to prospectively compare the clinical outcomes (local tumor progression rate, technical success rate, complication rate) of no touch radiofrequency ablation (RFA) technique for Hepatocellular carcinoma (HCC) to those of conventional tumor puncture RFA technique.

To determine the Maximum Tolerated Dose (MTD), and the recommended Phase 2 dose of HIA Ipilimumab in combination with IV Nivolumab by monitoring the Dose Limiting Toxicity (DLT) within 1 month after IA Ipilimumab administration in dose-escalation phase.

The study comprises a main study of pembro-treated HCC patients and a sub-study of untreated HCC patients. In the main study, patients will be treated with pembrolizumab as neoadjuvant treatment approximately 4 weeks prior scheduled surgery. Adjuvant treatment with pembrolizumab with commence at approximately 4 weeks post-surgery for up to 12 months. Subjects will be followed up for a further 12 months after end of treatment for recurrence and survival. The sub-study is a tumour sample collection study which will provide pre-treatment immune microenvironment data from up to 15 pairs of HCC/adjuvant liver tissue samples. Translational analyses performed for liver tissue samples in the sub-study will be harmonized with the analyses on liver tissue samples collected in the main study.

Background: Removal of part of the liver (resection) is performed as a treatment for some cancers in the liver. To achieve the best possible outcomes, it is important that the cancer is removed completely (R0 resection) (1). Up to 30-50% patients develop recurrence within 2 years of surgery which could be due to incomplete removal of the cancer (2). Various techniques are used by the surgeons to identify the cancer tissue from the normal liver during the surgery so that it can be removed completely. These include examining with the naked eye, having a feel of the tumour, and performing an ultrasound scan. Even with these techniques it is difficult to identify the exact extent of the cancer. Also, the interpretation of the ultrasound scan can be subjective (3). A robust, objective, real-time navigation technique is required which can differentiate cancer from normal tissue. Indocyanine green (ICG) is a dye which when given through the veins, is taken up and retained by cancer cells in the liver and they appear as fluorescent areas as compared to normal liver which appears dark. This principle can be used to identify the cancerous tissue accurately during the surgery and remove it completely (Indocyanine green Fluorescence Image-Guided Surgery: I-FIGS). It can also potentially detect additional tumours which were not identified before the surgery or during the surgery with standard techniques (4,5). However, there is a lack of good quality evidence on the usefulness of I-FIGS in liver surgery, so this needs to be tested in a large group of patients having liver surgery before any recommendations can be made. Research Aim: This initial study aims to assess whether a larger trial evaluating the role of I-FIGS in complete removal of the cancer tissue is feasible. Investigators will assess if patients are willing to take part in the study and whether they can gather relevant clinical outcome data from them all. Investigators will also gather patients' views about this novel technique and participating in the study. Design and methods: This study will involve 40 patients having planned liver surgery for liver tumour/s recruited from University Hospitals, Plymouth. Patients will be randomly allocated to have I-FIGS plus standard surgery or standard liver surgery alone. Patients in the I-FIGS group will have ICG injection 2-4 hrs prior to surgery (0.03-0.05mg/kg dose) on the day of surgery. The surgical planning will be carried out as per the standard approach using the naked eye and intra-operative ultrasound examination. Once this is all recorded, ICG cameras will be switched on, and the additional findings and change to surgical plan will be noted. Focus groups will explore participants experiences of being in the study. This will inform the design of the future larger trial. Patient public involvement: Investigators have involved patients who have had or are having liver surgery in the development of the study. Their views on the technique, trial procedures and outcome measures have been incorporated. They will continue to be involved and advise on the study. Dissemination: Results will be available via research journals and conferences.

To evaluate local tumor progression rate at 12 months after no-touch percutaneous radiofrequency ablation using combined energy delivery mode and triple cooled electrodes

To validate the tumor response rate: in the previous study, the investigators showed that TILA-TACE achieved 100% tumor response rate. However, as the study sample size was 40, the investigators need to validate the tumor response rate using a larger sample size; To validate the overall survival: in the previous study, the investigators showed that TILA-TACE significantly prolonged the overall survival of the patients with large and massive tumor. Again, the sample size was small, the investigators need to validate the data using a large sample size.
