Filter by: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.
The aim of this study is the safety and efficacy of cryosurgery plus natural killer(NK) immunotherapy to tumors in transplanted liver.
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.
This is a phase 1b/2, multicenter, open-label, basket trial to evaluate the safety of talimogene laherparepvec injected intrahepatically into liver tumors alone and in combination with systemic intravenous (IV) administration of pembrolizumab, in subjects with non-hepatocellular carcinoma (HCC) liver metastases from breast adenocarcinoma (BC), colorectal adenocarcinoma (CRC), gastroesophageal cancer (GEC), melanoma, non-small cell lung cancer (NSCLC), clear cell renal cell carcinoma (RCC) in Part 1 Group A, and subjects with HCC with and without viral hepatitis in Part 1 Group B (viral hepatitis is only applicable in combination setting), and to evaluate the efficacy and safety of intratumoral talimogene laherparepvec in combination with systemic pembrolizumab in subjects with advanced triple negative breast cancer (TNBC), hormone receptor positive breast cancer, CRC, cutaneous squamous cell carcinoma (CSCC), and basal cell carcinoma (BCC) in Part 2 Group A and subjects with HCC with and without viral hepatitis in Part 2 Group B. The objective of Part 1 is to evaluate the safety of intrahepatic injection of talimogene laherparepvec into liver tumors alone and in combination with systemically administered pembrolizumab for the non-HCC (Group A) and HCC (Group B) cohorts separately. Part 2 consists of 2-stage design to evaluate the efficacy and safety of talimogene laherparepvec in combination with systemic pembrolizumab. Efficacy and safety will be evaluated in each of the five non-HCC tumor types from Group A separately. Similarly, the efficacy and safety of the combination treatment will be determined for Group B HCC subjects. As of Protocol Amendment 6 (dated 26 October 2021), intrahepatic injections of talimogene laherparepvec and liver biopsies are no longer performed in this study. Enrollment for this study has stopped.
The purpose of this study is to prospectively analyze the value of 3D ultrasound perfusion imaging for treatment planning, the prediction of therapy success, and to monitor the treatment response in patients with a primary or metastatic liver tumor undergoing radiation treatment.
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).
The purpose of this research is evaluate the results with laparoscopic ALPPS procedure in a single center. The validity, feasibility and limitations were assessed objectively through our clinical prospective study.The investigators expect laparoscopic ALPPS is safe, effective and feasible.
One of the limiting factors in the execution of a liver resection, in particular an extended liver resection, it's represented by the future remnant liver (FRL) after hepatic surgery. In cases of normal organ function an FRL of 25% is considered sufficient. In case of impaired hepatic function or a history of chemotherapy, it is considered safe if at least of 40%. Many strategies have been developed and proposed to increase the resectability in patients undergoing major liver resections. One of these is a new two-stage technique proposed recently by a group of German surgeons. This approach consists in the ligation of the right portal vein associated with resection of the liver along the falciform ligament (step 1). Step 2, after a period of 9 days (median - 5-25 days), after a volumetric CT to ensure an adeguate hypertrophy of the left lateral lobe due to the combination of right portal occlusion and segment 4 devascularization, the patient undergo a right trisectionectomy. The hypertrophy of the left lateral lobe is shown to be of 74%, higher than any other techniques of ligation or portal embolizatiol proposed in the literature. On the basis of the clinical experiences reported the investigators designed a new protocol of two-stage hepatic resection for the treatment of primary or secondary tumors of the right lobe. Step1: laparoscopic radio frequency / microwave ablation of the future transection plane between segment 4 and left lateral lobe and surgical ligation or embolization of the right portal vein. The ablation has the purpose to devascularize the segment 4 and has the same significance of the resection of the liver along the falciform ligament described by the Regensburg group. Step2: After a period of time of 9 ± 2 days, following a volumetric CT showing an adequate liver volume gain (ratio FRL / patient body weight> 0.5), the patient undergo the second-stage surgery: laparoscopic/ laparotomic right trisectionectomy.
This proof of concept study proposes targeted delivery of a broad-spectrum cytotoxic agent (doxorubicin), via a specially formulated LTSL (ThermoDox®) activated by mild hyperthermia, by using focused ultrasound (FUS), to achieve enhanced intra-tumoural doxorubicin concentrations for the same systemic dose. Adult patients with incurable confirmed hepatic primary or secondary tumours received a single cycle of LTLD, followed by ultrasound-mediated hyperthermia to a single target liver tumour. The primary endpoint relates to evidencing enhanced delivery of doxorubicin from LTLD at the target tumour site, by comparing intratumoural concentrations of the drug before and after focused ultrasound (FUS) exposure.
The purpose of this study is to test the feasibility (ability to be done) of experimental technologies to determine a tumor's molecular makeup. This technology includes a genomic report based on DNA exomes and RNA sequencing that will be used to discover new ways to understand cancers and potentially predict the best treatments for patients with cancer in the future.
