Active clinical trials for "Liver Neoplasms"

Detect plasma Hsp90α concentration of liver cancer patients, healthy volunteers, benign liver diseases.

Colorectal cancer is a major cause of mortality worldwide. Most patients develop colorectal liver metastases (CLM), and for such patients hepatectomy combined with chemotherapy may be curative. Nevertheless, in the era of precision medicine there is a critical need of prognostic markers to cope with the heterogeneity of CLM patients. Tumor-associated macrophages (TAMs) pave the way to tissue invasion and intravasation providing a nurturing microenvironment formetastases. The quantification of immune landscape of tumors has provided novel prognostic indicators of cancer progression, and the quantification of TAMs might explain the heterogeneity of CLM patients. Here, we will investigate the development of a new diagnostic tool based on TAMs with the aim to define the causative role of TAMs in CLM patients. This will open new clinical scenarios both for the diagnosis, therapy and prognosis, leading to the refinement of the therapeutic output in a personalized medicine perspective.

Medical records are reviewed to obtain information about the use of a MRI diagnostic imaging agent (contrast agent) called Primovist/Eovist in children older than 2 months and less than 18 years. Data that has been recorded in the child's medical records relating to the injection of Primovist/Eovist will be collected. Information will be collected from up to 2 weeks before the child received Primovist/Eovist until 12 months after the child received Primovist/Eovist. Copy of the child's MR images that were taken right before and after the child received Primovist/Eovist and all other reports (laboratory reports, other imaging reports, etc) that are part of the child's medical records during that time period will be collected.

The objective of this study is to evaluate for the first time not only the impact of neoadjuvant chemotherapy on clinical outcome, but also on liver regeneration after liver resection.

The purpose of the study is to determine whether anticoagulant use (i.e. salicylates, clopidogrel, low-molecular weight heparin, or coumarin derivates) is able to prevent the development of the sinusoidal obstruction syndrome secondary to oxaliplatin-based neoadjuvant chemotherapy in patients suffering from colorectal liver metastases.

Estimation of functional liver reserve in patients with hepatocellular carcinoma (HCC) in cirrhosis is of paramount importance to properly select candidates for surgical resection. Together with the value of bilirubin, the presence/absence of ascites and esophageal varices, and the rate of residual liver volume, which are our current parameters to measure functional liver reserve, the investigators sought to investigate the value of preoperative cholinesterases (CHE) in predict postoperative adverse outcome after hepatic resection for HCC.

This comparison study is performed to show equivalence of CEUS with CECT or CEMR to diagnose noninvasively focal liver masses. This is a multi-center prospective cohort study of 250 subjects, which will be performed at four institutions in Canada. Subjects with a focal liver mass, measuring at least 2.5 centimeters in maximal diameter, will undergo a conventional baseline sonogram followed by a contrast enhanced ultrasound (CEUS). CEUS will be performed on standard ultrasound scanners with contrast specific imaging capability. The contrast agent used is Definity (Lantheus Medical Imaging, Billerica,MA) All subjects will have either a dedicated hepatic contrast enhanced CT or MR scan within 60 days of the CEUS as per the standard of care in the institution. Anonymized image files from all imaging will be shown independently to two readers, blinded to all clinical and demographic data, who will predict malignancy and diagnosis.

RATIONALE: Internal radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Using radiolabeled glass beads to kill tumor cells may be effective treatment for liver cancer that cannot be removed by surgery. PURPOSE: To provide expanded access and study the side effects of yttrium Y 90 glass microspheres in treating patients with liver cancer that cannot be removed by surgery.

To develop a real-time diagnostic technique with e- Ab sensor for specific LECT2 detection in clinical specimens of Hepatocellular carcinoma (HCC) patients, the investigators conduct a prospective clinical study. In comparison with results from direct sequencing of LECT2, the investigators evaluate the performance of e- Ab sensor, including reproducibility, sensitivity, specificity, and cross-reaction. With such technique, the investigators can obtain LECT2 information of HCC patients in cost-saving and time-saving way and can offer more individualized treatment for our patients.

Microwave thermal ablation (MO) is recognized as an alternative to surgery for the local-regional treatment of primary and secondary hepatic and renal tumors and for secondary pulmonary tumors in patients at anesthetic and/or surgical risk. Microwaves have a reputation for not producing reproducible ablation volumes with elliptical deformations and risks of over or under processing. The Covidien manufacturer offers a microwave system that guarantees more spherical and reproducible ablations: Emprint TM ablation system with Thermosphere TM technology (thermal control, field control, wavelength control). The investigators have 2 years of experience and therefore propose to carry out a first retrospective study, on a cohort of about fifty patients, whose objective will be to compare the volume of in vivo ablation one month after thermo-ablative treatment by microwave of a hepatic, renal or pulmonary tumour with the reference volume announced by the Covidien abacus manufacturer. Microwave ablation, which is much less studied, is less used because of the low reproducibility of necrosis volumes. The Covidien manufacturer offers a system that allows ablation volumes that are supposed to be reproducible, which attracted the Nîmes University Hospital during the call for tenders. To the investigator's knowledge, there are no studies that have evaluated the actual volume of ablation by this system.
