Active clinical trials for "Liver Neoplasms"

The purpose of this study is to prospectively analyze the value of 3D ultrasound perfusion imaging for treatment planning, the prediction of therapy success, and to monitor the treatment response in patients with a primary or metastatic liver tumor undergoing radiation treatment.

The purpose of this study is to draw blood from vessels near the liver in patients undergoing liver surgery. This will be performed in both patients with cancer in order to learn more about circulating tumor cells, proteins and DNA mutations in the blood. The blood in patients with colorectal cancer with liver metastases will be compared to blood taken from patients that do not have cancer that do not have cancer. Inclusion of patients with benign pathology will allow for the establishment of "normal" values which currently do not exist. We will then study whether tumor mutations can be used to predict recurrence and survival patterns.

In this study, the investigators assessed whether intraoperative Intraportal infusion of 5-FU and oxaliplatin is able to prevent liver metastasis in patients receiving curative colorectal cancer resection.

The purpose of this study is to verify the superiority of NIK-333 (Peretinoin) to placebo in inhibiting the recurrence of HCV-positive HCC in patients showing complete cure of the disease, with the recurrence-free survival as the primary endpoint, in a multi-center, randomized, double-blind, placebo-controlled, parallel-group comparison study.

FORCE project aims to measure actives forces of malignant tumor by magnetic resonance force (FRM). Two main forces are considered as key indicators of therapeutic response and metastatic potential: interstitial force and traction force at the interface cell/tumor. Biomarkers of these forces will be developped using direct images of magnetic resonance force (FRM). Efficiency of these non-invasive biomarkers will be evaluated through their capacity to predict tumoral environment invasion, notably micro-vascular invasion, and therapeutical results in Hepatocellular Cancer (HCC). Principal criteria will be micro-vascular invasion assessed by pathological examination of surgical pieces (gold standard). interstitial force and traction force at the cell/tumor interface assessed by FRM. Population of patients will be divided in three groups. A first group will be constituted of 20 volunteer patients coming for abdominal MRI with no known hepatic disease, in order to determine the feasibility of FRM. A second group will be constituted of 60 patients with resectable HCC eligible for surgery. This group will enable to evaluate the tumoral environment invasion. Third group will be constituted of 50 patients with HCC eligible for transplant with transcatheter arterial chemoembolization (TACE) treatment as pending treatment before transplant. This groups will enable to evaluate the efficiency of TACE through the necrosis percentage in treated HCC. Inclusion of patients will occur during 24 months for a total study duration of 36 months. All patients will have MRI as usual care. FRM is performed during MRI with the use of a specific medical device and therefore corresponds to an additional procedure of the research. Moreover, patients in group 2 and 3 will be asked to participate to an ancillary study consisting in circulating tumoral cells (CTC) measurement. If they accept, a blood sample will be collected just before the MRI in order to evaluate the correlation between CTC and micro-vascular invasion.

The purpose of this study is to collect and store normal and malignant tissue from patients with gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer, an estimated 50 to 100 of each tumor type. To collect and store blood samples from patients with gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer. To create a database for the collected tissue and allow access to relevant clinical information for current and future protocols. To create tissue microarrays for each gastrointestinal cancer subtype, namely, gastric cancer, GIST, esophageal cancer, pancreas cancer, hepatocellular cancer, biliary cancer, neuroendocrine, peritoneal mesothelioma, anal cancer and colorectal cancer, to facilitate future molecular studies. To grant access to Dr Kindler, Dr. Salgia, and Dr. Catenacci to this database (as it is being acquired) of the coupled patient tissue samples (normal and malignant) and relevant clinical information for the investigation of tyrosine kinases, such as Met and Ron, receptor tyrosine kinase family members, STATs, paxillin, focal adhesion proteins, cell motility/migration proteins, tyrosine/serine/threonine kinase family members, related molecules, and downstream targets implicated in the pathogenesis of GI cancers. Examples of molecular testing include evaluation of DNA mutation, alternative splice variants, protein expression and phosphorylation, and immunohistochemistry on samples. These studies will be correlated with clinical information as stated above.

The purpose of the investigators study is to prospectively evaluate whether radiotherapy as an adjuvant therapy after RFA will improve the outcome of radiofrequency ablation for hepatocellular carcinoma (HCC) or not.

The purpose of this study is to test a new and possibly more accurate method of positioning patients with liver tumors in preparation for radiation treatment. The positioning of patients with liver cancer is important because the tumor moves a bit when you breathe and makes it hard to determine the right position of the tumor at the time of treatment. Also, depending upon what is in your stomach at the time of treatment, it may change the shape of the liver and make it difficult to plan the radiation treatment. As part of this study, we will take a new type of image of your liver in addition to the standard portal images. This new type of image is called a cone-beam image. It shows a much more detailed picture of the liver tumors than the standard portal images. Normally, marker seeds need to be placed near the liver metastasis for radiation treatment. If the results of this study show that the tumor can be positioned as accurately with the new images as with the old images, then future patients with liver tumors would not have to have marker seeds placed into their liver. The use of cone beam imaging for the setup of patients with liver tumors is new.

A few studies have documented that some patients can be down-staged from an initially inoperable state to a potentially resectable state. Five-year survival in initially inoperable patients that ultimately come to a complete resection appears to be similar to patients who are resected at first presentation. The investigators goal is to assess the rate of conversion to complete resection in patients with initially inoperable liver-only metastases due to colorectal cancer after treatment with HAI of oxaliplatin with FOLFIRI and bevacuzimab systemic treatment.

This is a pilot study that uses a standard of care technique, Stereotactic Body Radiation Therapy (SBRT), in combination with Dynamic Contrast Enhanced Computed Tomography (DCE-CT) to determine if perfusion changes from SBRT of liver cancer may be used for outcome assessment and prediction of prognosis.
