Active clinical trials for "Liver Neoplasms"

Radioopaque fiducial markers or electro-magnetic transponders will be implanted into or in close proximity of the tumor. During a radiotherapy treatment session image and/or signal acquisition will be performed by ultrasound, computed tomography, magnetic resonance imaging or by specialized signal detectors The data will help to characterize tumor and organ motion during one treatment session which may in fact have impact on dose distribution

The results of this study may or may not establish useful baseline data, which will help us understand how bone marrow derived adult liver stem cells behave in normal healthy adults/volunteers (the control group), and in patients undergoing liver surgery. The bone marrow is located within your bones and is the organ which is responsible to produce blood cells and stem cells. Bone marrow derived adult liver stem cells are normal cells in your bone marrow. These liver stem cells have the capacity to regenerate or in other words to rebuild the liver after liver surgery, a process called liver regeneration. These cells are very important for the liver to regrow its tissue after liver surgery. These cells are thought to be activated in times of need by the liver. Situations like liver surgery are one of these occasions when the liver will need the "extra help" from these stem cells. The results of this study will establish the baseline data necessary for the understanding of how to harness the ability of these stem cells in times of liver surgery. Improvements in the ability of the liver to regrow after surgery is thought to decrease complications related to liver surgery. Harnessing this unique ability of stem cells may be utilized in the future to enhance the regrowing process of liver tissue after liver surgery, called liver regeneration.

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This laboratory study is looking at biomarkers in stored tumor samples from younger patients with liver cancer.

Background: Fibrolamellar Hepatocellular Carcinoma (FL-HCC) is a rare liver cancer. It usually occurs in young people who have no history of liver disease. Currently the only effective treatment option is surgery that removes the tumor and part of the liver. Researchers want to study the course of the disease to learn more about it. Objective: To collect samples from people with FL-HCC to learn more about the disease and help develop new treatments. Eligibility: People any age with FL-HCC Design: Participants must be enrolled on another NIH protocol. Participants will have at least 1 study visit. They will have: A medical and cancer history A physical exam A review of their symptoms and their ability to do normal activities Tests to produce images of the body. They may have a scan (CT) that uses a small amount of radiation. Or they may have a scan (MRI) that uses a magnetic field. These will examine the chest, abdomen, and pelvis. Blood tests Researchers will study previous tumor samples if they are available. If participants come to NIH for visits on other studies, data will be collected about their disease, tests, treatments, and responses. Tumor tissue will be collected if participants are having it taken for a procedure. All other participants will be contacted to collect this data. They will be contacted once a month for 1 year and 2 times a year after that. Participants will be asked to contact researchers when their health changes. They may come in for more tests.

The purpose of this protocol is to pathologically evaluate the destruction by microwave ablation of primary and metastatic liver tumors. The primary aim is to measure tissue destruction with the MedWaves Microwave Ablation/ Coagulation Ablation System.

This is a large-scale study in China to provide evidence and insights in the role of gender in LT for HCC by analyzing the data of 3769 recipients with HCC registered in the China Liver Transplant Registry.

This is a multi-center study in China to investigate the role of PIVKA-II in HCC recipient selection and prognostic stratification by analyzing the data of 522 recipients with HCC registered in the China Liver Transplant Registry.

Circulating tumor cells (CTCs) have the potential to provide a surrogate for'real-time biopsy' of tumor biological activity. Enumeration and molecular characterization of CTCs in liver cancer could play an important role in diagnosis, predicting the risk for tumor recurrence, and providing novel target therapy biomarkers. In view of these facts, the investigators wanted to demonstrate the value of multiparameter flow cytometry in detecting human tumor cells of liver cancer in normal peripheral blood after cryosurgery with or without dendritic cell(DC)-cytokine-induced killers(CIK) treatment, and the investigators also compared the specificity with reverse transcriptase polymerase chain reaction (RT-PCR) method.

The purpose of this study is to estimate the clinical value of contrast-enhanced ultrasound in percutaneous biopsy for liver occupied lesion.
