Active clinical trials for "Liver Neoplasms"

The purpose of this study is to evaluate the effectiveness and safety of relatlimab in combination with nivolumab in participants with advanced liver cancer who have never been treated with immuno-oncology therapy, after prior treatment with tyrosine kinase inhibitor therapy.

This randomized phase III trial studies sorafenib tosylate and stereotactic body radiation therapy to see how well they work compared to sorafenib tosylate alone in treating patients with liver cancer. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Stereotactic body radiation therapy may be able to send the radiation dose directly to the tumor and cause less damage to normal tissue. Giving sorafenib tosylate together with stereotactic body radiation therapy may kill more tumor cells.

The purpose of this study is to determine if Magnetic Resonance guided High Intensity Focused Ultrasound ablative therapy is safe and feasible for children, adolescents, and young adults with refractory or relapsed solid tumors.

This trial is a single arm, non-randomized prospective trial. The objective of this trial is to evaluate the efficacy and safety of the HistoSonics System for the treatment of primary or metastatic tumors located in the liver.

The purpose of the study is to find out the effects of using nivolumab with Drug Eluting Bead Transarterial Chemoembolization (deb-TACE) in the treatment of liver cancer.

This first time in human study is intended for men and women between 18 and 75 years of age who have advanced liver cancer which has grown or returned after being treated or another AFP expressing tumor. Those who did not tolerate or refused other therapies may also participate. The purpose of this study is to test the safety of genetically changed T cells that target alpha-fetoprotein (AFP) and find out what effects, if any, they have in subjects with liver cancer or other AFP expressing tumor types. This study is for subjects who have a blood test positive for appropriate HLA-A*02 P Group and have adequate AFP protein in blood or tumor, and whose noncancerous liver tissue has very little AFP protein (Liver only). The study will take the subject's T cells, which are a natural type of immune cell in the blood, and send them to a laboratory to be modified. The changed T cells used in this study will be the subject's own T cells that have been genetically changed with the aim of attacking and destroying cancer cells. The manufacturing of T cells takes about 1 month to complete. The T cells will be given back to the subject through an intravenous infusion after 3 days of chemotherapy. The study will evaluate three different cell dose levels in order to find out the target cell dose. Once the target cell dose is determined, additional subjects will be enrolled to further test the safety and effects at this cell dose. Subjects will be hospitalized for at least 1 week after receiving their T cells back and then seen frequently by the Study Physician for the next 6 months. After that, subjects will be seen every three months. If subjects have disease progression or withdraw from the study, they will then be entered into a long-term follow up for safety monitoring. In long-term follow up, subjects will be seen every 6 months by their Study Physician for the first 5 years after the T cell infusion and annually for the next 10 years.

We are performing a pilot and feasibility randomized controlled trial (RCT) of HCC screening by US + AFP every 6 months (n=100), the current standard-of-care, versus aMRI + AFP every 6 months (n=100) for 12 months (i.e. at time 0, 6 and 12 months) among AI/AN patients with cirrhosis or HBV.

To explore the utility of personalized 3D printed liver models in planning and navigating laparoscopic resections.

Liver cancer is the sixth most commonly diagnosed cancer and the fourth leading cause of cancer death worldwide. It is the 3rd most common cause of cancer death in Hong Kong. The five-year survival rates of liver cancer differ greatly with disease staging, ranging from 91.5% in early-stage to 11% in late-stage. The early and accurate diagnosis of liver cancer is paramount in improving cancer survival. Liver cancer is diagnosed radiologically via cross sectional imaging, e.g. computed tomography (CT), without the routine use of liver biopsy. However, with current internationally-recommended radiological reporting methods, up to 49% of liver lesions may be inconclusive, resulting in repeated scans and a delay in diagnosis and treatment. An artificial intelligence (AI) algorithm that that can accurately diagnosed liver cancer has been developed. Based on an interim analysis, the algorithm achieved a high diagnostic accuracy. The AI algorithm is now ready for implementation. This study aims to prospective validate this AI algorithm in comparison with the current standard of radiological reporting in a randomized manner in the at-risk population undergoing triphasic contrast CT. This research project is totally independent and separated from the actual clinical reporting of the CT scan by the duty radiologist. The primary study outcome is the diagnostic accuracy of liver cancer, which will be unbiasedly based on a composite clinical reference standard.

Background and aim: FLLs are common findings in abdominal ultrasound and differential diagnosis between benign and malignant lesions is often challenging, especially in patients with chronic liver diseases. The diagnostic role of CEUS has already been defined by international guidelines when lesions show a typical pattern for hepatocellular carcinoma whereas in case of non-typical contrast enhanced patterns radiologic imaging or liver biopsy are still needed. However, these techniques are more invasive and expensive than ultrasound. Therefore, the aim of this study is to identify D-CEUS and SWE quantitative parameters useful for characterizing FLLs. Study design: Prospective, observational, single-center study Methods: 50 consecutive adult patients with focal liver lesions detectable with B-mode ultrasound will be enrolled in the Unit of Internal Medicine and Gastroenterology of the Policlinico Gemelli. Exclusion criteria will be liver failure, hearth failure, previous locoregional or systemic treatments for FLLs (e.g. ablation, chemoembolization, alcoholization, chemotherapy), known allergy to ultrasound contrast agents. After obtaining informed consent and identifying the target lesion in B-mode ultrasound, patients will undergo CEUS and SWE and, subsequently, to computed tomography/magnetic resonance/biopsy according to international guidelines and current clinical practice. The average, maximum, minimum and standard deviation value of lesion elasticity in KPa will be calculated using SWE. Three consecutive SWE acquisitions will be performed both for the lesion and for the liver parenchyma and the average value of the three measurements will be considered. The CEUS will allow the construction of signal intensity curves as a function of time in a specific area of interest drawn manually. From these curves a series of quantitative parameters related to the flow and volume of blood will be extrapolated and in particular: peak intensity, PI (in Arbitrary Units, AU); time to peak, TP ( in seconds); area under the time curve, AUC (in AU); slope of the wash-in curve, Pw (in AU per second); average transit time, MTT (in seconds). In addition, the personal, clinical and laboratory data necessary to determine the hepatological scores of disease severity such as MELD and Child-Pugh will be collected. The study has an expected duration of one year.
