Active clinical trials for "Liver Neoplasms"

Hepatocellular carcinoma (HCC) is the fifth most common cancer and the second leading cause of cancer-related deaths in the world. Hepatitis C virus (HCV) is the most common underlying cause of cirrhosis and HCC in the western world. The staging of the disease is done by combining blood tests and imaging tests. Ultrasound scanning, computed tomograph (CT) and magnetic resonance imaging (MRI) scans are methods based on identifying or significant change in the liver. Those changes are sometimes difficult to identify, especially when there are changes in liver structure resulting from disease, such as cirrhosis of the liver. In many cases it is also difficult to detect secondary scattering in anatomical tests, such as identifying a disease in normal size lymph nodes or early skeletal dissociation. Functional imaging is not based on structural changes, but on the ability to detect changes in the function and properties of the tissue, such as a change in the cell's metabolic consumption or the presence of proteins that characterize the tumor tissue.PET scans can show tumor cell activity (the cancer cells are more aggressive, get more sugar and therefore see more absorption in PET), detect small tumors and metastases outside the liver (because they do a whole body test). To complete this test, a CT scan is also performed on the same device (PET-CT scanner). There is a new material called prostate-specific mRNA that is marked with gallium isotope (Ga-68-PSMA). It is the substance that is absorbed into the cells of the blood vessels of the tumor. The Ga-68-PSMA is now widely used in the diagnosis of prostate cancer. The new researches also found the possibility of using Ga-68-PSMA in primary liver cancer in patients because of the over-expression of the antigen in the blood vessels. Therefore, the tests with Ga-68-PSMA and F-18-FDG will complement each other and will give a complete picture of the extent of the disease. Each patient has individual characteristics of the tumor, and according to the results it will be possible to adapt the test to the patient with the appropriate material for the disease and this will be effective for the decision to treat and follow up. At the end of the study it will be possible to offer the study participant the appropriate functional imaging test.

In this retrospective study, the investigators assessed the application of radiofrequency-assisted liver resection in intractable liver cancer resection, and plan to analysis the different factors.

Postoperative delirium（POD）is a common complication that can directly affect important clinical outcomes, and exert an enormous burden on patients, their families, hospitals, and public resources. In order to evaluate whether an intraoperative administration of low-dose neuroleptanalgesia reduces postoperative delirium, droperidol 1.25 mg and fentanyl 0.025 mg or normal saline is used by intravenous injection 30 minutes before the end of the operation, in elderly patients with non-cardiac major surgery under general anesthesia. The efficiency and safety of neuroleptanalgesia on the incidence of POD would be evaluated in elderly patients.

Liver metastasis may not be detected by CT and MRI due to their small size while they can be detected by EUS. Also, EUS-FNA has a great impact in improving the diagnostic accuracy of EUS. Objectives: To assess the feasibility of EUS in the detection of occult small hepatic focal lesions at the time of primary tumor staging, not seen by CT or MRI.

Major hepatectomies are generally selected for tumors involving the hepatic vein (HV) at the caval confluence (CC). As alternative, HV reconstruction has been proposed. The present study aimed to evaluate the feasibility and safety of a HV-sparing policy guided by intraoperative ultrasonography (IOUS) in a cohort of patients having at least one colorectal liver metastasis (CLM) in contact with a HV at CC. HV section can be avoided in the large majority of cases thanking to CLMs detachment or to HV partial resection or reconstruction: this policy seems feasible, safe, reduces the need of major hepatectomies, and oncologically provides an adequate local control.

This is a prospective, monocentric, non-randomized, phase I-II study. The goal is to assess the faisability and the capabilities of fluorescence imaging in hepatic surgery, and specially to help the surgeon while performing liver surgery. This study will be performed on patient intended to undergo a liver cancer surgery.It will contain three steps, assessing the following items: Step 1: to assess the faisability of the use of the Fluobeam, in actual clinical surgical conditions and validate the data obtained in the preclinical phase, Step 2: to assess the ability of the combination of ICG and Fluobeam to mark hepatic lesions, Step 3: to assess the ability of the combination of ICG and Fluobeam to help in guiding per-hepatectomy. 3 to 6 patients will be enrolled in the first step, 20 in the second step and 20 in the third step. Patients will be followed during 4 weeks after the surgery.

Recurrence and metastasis are the main factors affecting the prognosis of liver cancer after curative resection. Establishing an effective prognostic evaluation method is able to not only assess patients' prognosis but also guide the treatment. At the same time, it helps us to gain knowledge of the mechanism underlying recurrence and metastasis of liver cancer and to provide the basis for the search for new effective intervention method. In order to establish an effective prognostic evaluation method, we select liver cancer patients undergoing curative resection in our hospital. We plan to employ various technologies such as gene chip, methylation chip and flow cytometry to carry out comprehensive researches on liver cancer cell genetics, epigenetics, stem cells and tumor microenvironment changes. By analyzing clinical information including pathological features, patients' response to treatment, relapse, metastasis and survival, we aim to obtain the important factors affecting liver cancer prognosis, survival, recurrence and metastasis in order to be able to find and establish the effective prognostic evaluation method.

This study is designed for patients diagnosed with Liver cancer to collect information about the relationship between types of liver cancer, methods of treatment and outcomes over time.

The purpose of this study is to prospectively compare the physiologic response of patients who receive either intravenous gadoxetic acid (Eovist) or intravenous gadobenate dimeglumine (MultiHance).

RATIONALE: Gathering health information about patients with liver cancer over time may help doctors learn more about the disease and may help the study of cancer in the future. PURPOSE: This clinical trial is developing a national registry and blood bank of patients with liver cancer.
