Active clinical trials for "Liver Neoplasms"

Retrospective analysis of a prospectively collected database of 170 patients between 2004 and 2020, who underwent liver resections for CRLM (colorectal liver metastases) at The Queen Elizabeth Hospital trying to determine rates and patterns of recurrence following liver resections for CRLM and concurrently, characterise clinical, pathological and treatment-related factors that could function as predictors of recurrence or survival, particularly neoadjuvant chemotherapy and tumour clearance.

To evaluate the diagnostic performance of two-dimensional shear-wave elastography (SWE) for staging hepatic fibrosis in the background liver parenchyma in patients with liver tumors before hepatic resection, using resected tissue pathology as a reference standard.

A single-centre, industry sponsored, proof-of-concept pilot study to assess the feasibility of Electromagnetic Acoustic Imaging (EMA) as an imaging platform in the visualization of hepatic tumours.

Aim of this prospective national multicenter study is to improve standardization of contrast-enhanced ultrasound (CEUS) in the non-invasive diagnosis of hepatocellular carcinoma (HCC) in high-risk patients. The study is funded by the German Society for Ultrasound in Medicine (DEGUM).

The performance of multiple minor hepatectomies (MMH) instead of major hepatectomies (MH) in patients with colorectal liver metastases (CLM) is object of debate. We build a study, using the propensity score matched analysis, to compare the short- and long-term outcome of the tow groups of patients.

This research trial is studying biomarkers in tissue samples from young patients with liver cancer. Studying samples of 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.

The collection of data regarding patient outcomes after surgical intervention creates imperative knowledge to include surgeon performance, cost analysis, base for surgical research and publication, which in turn assist surgeons to improve the standard of care utilizing evidence-based practice.

Objective: To evaluate the role of regional lymphadenectomy in patients with colorectal cancer liver metastasis. Background: Lymph node status is 1 of the most important prognostic factors in oncologic surgery; however, the role of lymph node dissection remains unclear for colorectal cancer liver metastasis.

This study was designed to confirm that the surgeon is able to perform surface registration of standard liver features used as landmarks during a scheduled laparoscopic liver procedure. Additionally, registrations will be obtained with full insufflation pressure and with half insufflation pressure during the laparoscopic procedure. Under the presence of both insufflation pressures, the surface of the liver will be manually swabbed with the study tracked laparoscopic probe with landmarks noted during data collection. After registration of the liver is obtained, the registration points obtained during this procedure will be evaluated by the surgeon by moving the tracked laparoscopic probe over the liver surface and evaluating the location of the tracked laparoscopic probe displayed on the guidance system 3D image. The surgeon will accept or reject the registration accuracy. Upon completion of the scheduled laparoscopic procedure, the subject will then undergo the open procedure scheduled for the surgical case. An open liver registration will be obtained with manual swabbing of the liver using the study tracked probe and will be accepted or rejected by the surgeon using the process described in the laparoscopic procedure. In the event that the disease is determined to be too great for surgical repair during the laparoscopic staging procedure, only minimally invasive liver surface data will be acquired and the patient will not be included in the overall study population.

Imaging with CT (Computed Tomography) or MRI (Magnetic Resonance Imaging) is normally used to see how tumors respond to treatment. If tumors shrink after therapy, doctors continue with the same treatment. On the other hand, growing tumors in a patient can bring about a change in therapy. Unfortunately, it often takes three to six months, or even longer before the investigators see tumors shrink or grow on scans. Doctors are looking for new imaging tools that can look at how tumors respond early on during treatment. This study will help us decide if such an MRI technology called DWI (Diffusion Weighted Imaging) can be used as a helpful imaging tool.
