The primary objective of this study is to develop and validate simultaneous free-breathing 4D fat and water quantification and quantitative dynamic contrast enhanced perfusion in the liver. Secondary aims include developing and validating free breathing quantification of relaxation parameters T1 and T2, and developing and validating a minimal breath-hold (< 8 s) high quality diffusion exam using highly accelerated steady state diffusion imaging sequences. Investigators aim to scan 100 subjects receiving liver biopsies as a part of their standard care and another 70 subjects with known benign lesions. The study is greater than minimal risk.
The purpose of the study is to evaluate the efficacy and safety of PEG-BCT-100 as the second-line therapy following sorafenib in advanced HCC patients. Another objective of the study is to explore whether the expression of OTC and ASS are predictive biomarkers for drug response and prognosis.
The propose of the study is to evaluate the maximum tolerated dose (MTD) of Oxaliplatin in combination with pegylated recombinant human arginase 1 (PEG-BCT-100) and Capecitabine and efficacy of this combination regimen (PACOX)in patients with advanced liver cancer.
Patient with advanced liver cancer (cancer that has spread to other parts of the body) continues to receive the study drug (G-202) even though patient no longer meets the criteria to be a part of the main treatment study. Patient's cancer responded well to receiving G-202 in the main study and will receive G-202 at the same dose given in the main study.
Liver cancer is a major cause of death among patients of east or southeast asian descent, as well as other population groups, notably in central and west Africa. Diagnosis of liver cancer requires a combination of several imaging techniques and biopsies. Despite this, diagnosis can remain inconclusive or difficult to establish in patients at risk for liver cancer. The purpose of this multi-center trial is to evaluate novel imaging methods developed to diagnose the most common form of liver cancer, hepatocellular carcinoma. We propose to use novel imaging probes that have been reported to bind to liver cancers but not benign liver lesions that can be confused with liver cancer. Two such imaging probes will be evaluated. 2-[18F]-fluoro-2-deoxy-D-glucose, called [18F]FDG, is a radioactive sugar that is widely used for cancer imaging with a device called positron emission tomography, or PET scans. We already know that [18F]FDG cannot detect some liver cancers that are slow growing. [18F]Fluorocholine ([18F]FCH), another molecule, has been recently reported to be highly effective at detecting liver cancer. In 2010, a French researcher reported 80-90% detection rate by using [18F]FCH alone or in combination with [18F]FDG. We will compare [18F]FCH and [18F]FDG in evaluating 150 patients over a period of two years. The results will be correlated with those of biopsies and clinical follow-up. This study will provide valuable data on whether these imaging agents can successfully differentiate malignant liver lesions from benign ones. It will also provide information about whether these imaging agents can successfully assess whether the cancer has spread outside the liver. It will provide data that will allow physicians to determine the optimal imaging protocol to properly diagnose liver cancer.
Hepatocellular carcinoma (HCC) is the 6th most common cancer worldwide and the third most frequent cause of death of cancer.Although with the development of medical science, more and more patients diagnose HCC at early stage, a lot of patients with HCC still continue to present with multiple tumors or port vein thrombosis. According to AASLD guidelines, these patients could received transcatheter arterial chemoembolization (TACE) or new agents as initial treatment. However, the intermediate group comprises a wide spectrum in terms of liver function and extent of tumour, and this may explain the large differences in survival reported for individual series. A simple, pragmatic and reliable prognostic index based on objective measures would be of value in providing information to patients, for stratifying patients entering clinical trials and in making meaningful comparisons between series reported in the literature.The aims of our study were (i) to identify predictors of survival in a cohort of patients undergoing TACE or TAE for unresectable HCC, (ii) to develop and validate a simple scoring system and (iii) to compare the new scoring system with the most frequently used prognostic systems for its ability to separate high- and low-risk patients.
HCC is classified as keratin (K) 19 positive or K19 negative. K19 is a biliary/hepatic progenitor cell (HPC) marker only expressed in a subset of HCC with poor prognosis and high risk of early recurrence after treatment; particularly in radio-frequency ablation (RFA). These patients consequently show worse survival compared to patients with K19 negative HCC. A recent publication has shown the value of pretreatment biopsy with K19 staining and suggests that the role of routine biopsies in potentially curable HCC should be reconsidered. However, currently, pretreatment biopsies are rarely performed in the diagnosis of HCC due to the excellent performance of magnetic resonance imaging (MRI) in detection, diagnosis and staging of cirrhotic livers. Previous publications have indicated imaging patterns that may be associated with worse prognostic tumoral parameters. If MRI determined imaging parameters could indeed provide a surrogate marker for presence of K19 and/or microvascular invasion as potential important prognostic factors in RFA of HCC, these imaging parameters may thus hold prognostic information towards RFA treatment and possibly predict treatment outcome. . The purpose of the retrospective study is thus to evaluate MRI determined imaging parameters at pretreatment MRI for their predictive value towards outcome (disease free survival) of radio-frequency ablation for hepatocellular carcinoma. If successful, pretreatment MRI parameters may be used for selecting patient with high risk of unfavorable outcome after RFA and select the patients for more aggressive treatment such as surgical resection or upfront transplantation.
The aim was to investigate the efficacy of radiofrequency ablation (RFA) with a multiple-electrode switching system (MESS) in the treatment of early hepatocellular carcinoma (HCC) and to evaluate the patterns and risk factors of intrahepatic recurrence of HCC after RFA.
Circulating free cell DNA (cfDNA) is extracellular fragmentation of nucleic acids that occurs both in plasma and serum. This kind of DNA which derived from the apoptotic/necrotic cells or the lysis of circulating tumor cells (CTCs) can be detectedin the patients with a variety of diseases. Emerging evidence suggests that cfDNA from patients exhibits characteristicchanges of tumors, suchas mutations, insertions/deletions, methylations,microsatellite aberrations, and copy number variations, etc. All of these reveal a visible difference between the benign conditions, and thus may be useful in the diagnosis of cancer, identification of targeted therapy, monitor responses to treatments, and early detection of relapse. The purpose for this study is to explore these characteristic changes in the patients withhepatocellular carcinoma (HCC) and expect to guide targeted therapy and identify non-invasive biomarkers of cancer diagnosis and prognosis which can be easily isolated from the circulation.
