NCT07265544
The purpose of this observational study is to employ single-cell multi-omics and spatial omics technologies to characterize the spatial and immune structures within the livers of patients with fatty liver, hepatic hemangioma, focal nodular hyperplasia, liver fibrosis, cirrhosis, and HBV infection. The primary questions it aims to address are: Investigate the mechanisms of liver degenerative changes during the processes of liver aging, fatty liver, HBV infection, liver fibrosis, and cirrhosis. Characterize the molecular features and cellular networks at different stages of liver degeneration and identify new targets and mechanisms for the cure of the aforementioned diseases. The study will collect peripheral blood and discarded liver tissue from patients with hepatic hemangioma, fatty liver, HBV infection, liver fibrosis, and cirrhosis who are undergoing hepatectomy or liver biopsy.
NCT04083378
This phase II trial studies how well software-aided imaging works in confirming tumor coverage with ablation (the removal or destruction of a body part or tissue or its function) on patients with liver tumors. The current standard for targeting tumor cells and evaluating the outcome of a liver ablation procedure is a visual inspection of the pre- and post-procedure computed tomography (CT) scans. Software-aided imaging systems, such as Morfeus, may help to improve the accuracy and effectiveness of liver ablation.
NCT07225114
This is a 4-arm, single-center study involving 40 participants. Ten healthy volunteers will be enrolled for system imaging optimization, and thirty (30) patients with previously identified lesions in the breast, liver, or kidney-based on prior ultrasound or cross-sectional imaging-will be imaged. Recruitment will be conducted such that ten patients are included from each anatomic region. The fourth arm will consist of 10 healthy volunteers who will be imaged to allow optimization of imaging parameters. Optimization is is required again due to the use of a different ultrasound system employing a new imaging technique. Parameters such as frame rate, power, depth of imaging, and linear translation rate will be adjusted during this process. The primary objectives of the study are to assess the sensitivity and specificity of Contrast Enhanced Super-Resolution (CESR) imaging in evaluating known lesions in the breast, liver, and kidney. These results will be compared with pathological findings. The secondary objectives are to compare the sensitivity and specificity of CESR imaging with those of traditional B-mode ultrasound in differentiating malignant from benign lesions in these same organs.

NCT06050200
Liver resection is the treatment of choice in patients with malignant liver lesions. Unfortunately, the surgery is not always an option, as in same patients the future remnant liver (FRL) is too small to supply all the functions. Therefore, some additional methods have been proposed to increase the size of the FRL. The aim of this study is to compare the efficacy and safety of three methods of increasing the future remnant liver - Portal Vein Embolization (PVE) - embolization of one of the portal branches; Liver Vein Deprivation (LVD) - embolization both of the portal branch as well as the hepatic vein; and partial ALPPS (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) - ligation of portal vein branch with partial liver transection. The efficacy of those three methods will be assessed both by analyzing the volumetric increase (by computer tomography scans) and by functional increase (by 99mTc-mebrofenin scintigraphy). Functional assessment of the liver hypertrophy seems to be of crucial importance, as some of the previous studies suggest that there might be a significant discrepancy in the increase of size comparing to the increase of function. This is a prospective, interventional randomized study. The study group (154 patients) will consist of patients being considered as candidates for major hepatic resection, after inducing hypertrophy of the future remnant liver. The primary study hypothesis is greater efficacy of ALPPS in preparing patients for large hepatic resection by inducing hypertrophy of the future remnant liver, as compared both to PVE and LVD. In case of unsuccessful induction of hypertrophy by the embolization techniques, patients may be qualified to rescue ALPPS procedure. Primary end-point: Percentage of patients with successful resection (patients, who gained sufficient increase of the FRL to proceed to the liver resection) with no post-surgical 90-day mortality. Secondary end-points: 1. the rate and degree of volume increase in different groups 2. the rate and degree of functional increase in different groups 3. CCI index and complication rate \>=3 degree according to the Clavien-Dindo classification after the first stage of treatment 4. CCI index and complication rate \>=3 degree according to the Clavien-Dindo classification after the second stage of treatment 5. overall duration of hospital stay Patient will be randomly assigned to the three study groups. All patients will undergo an abdominal contrast enhanced computed tomography and 99mTc-mebrofenin scintigraphy prior to the first stage of treatment. During the first stage of treatment, patients will undergo, according to their group: 1. Embolization of portal vein branch (PVE, portal vein embolization) 2. Embolization of both portal vein branch and hepatic vein (LVD, liver venous deprivation) 3. Partial ALPPS (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) - ligation of portal vein branch with partial liver transection, preferentially by laparoscopic technique Computed tomography scans and scintigraphy will be repeated at day 7, 14 and 21 after the first stage of treatment. The second stage of treatment, the liver resection, will be performed after achievement of sufficient mebrofenin clearance rate (\>=2,69%/min/m2). In case of failure to reach the desired clearance rate, the measurements will be continued every 7 days up to day 42. In case of uncertainty and discrepancy between the volumetric assessment in the computed tomography scan and the mebrofenin scintigraphy, it will be allowed to proceed to stage two (partial hepatectomy) after joint consultation of at least 3 hepatobiliary surgeons, 1 radiologist and 1 nuclear medicine specialist. Routine blood tests will be performed according to the standard procedure in the Department, depending on the patient clinical status. An additional blood sample will be collected from patients (after receiving and additional informed consent from the patient) and will be stored in the biobank. All patients will be monitored for surgical and 90-day complications. The volume increase after first stage of treatment, the functional increase after first stage of treatment, percentage of patients successfully proceeding to the second stage of treatment and complication rate will be calculated. The percentage of patients with complications \>= 3 degree in Clavien-Dindo classification and CCI index for each patient will be calculated. Furthermore, the blood test results will be assessed to search for associations with patients' outcomes. Any possible differences in terms of baseline patients characteristics between groups will be addressed. Statistical analysis will be performed using U Mann-Whitney test, exact Fisher's test, logistic regression, general linear models, Kaplan-Meier method and log-rank test. All three groups will be assessed in terms of occurrence of primary and secondary end-points.

NCT04518852
Hepatocellular carcinoma (HCC) is the fourth most common cause of cancer-related death that ranks sixth in terms of incident cases, with an overall 5 years survival of 18%. Despite a significant improvement in treatment strategy, the overall survival of HCC remains low due to high recurrence, progressive liver dysfunction and the high fatality of the disease. Surgical resection has been applied in a number of patients; however, surgery has been associated with a high incidence of recurrence (approximately 70% within 5 years). TACE is generally applied on intermediate-stage HCC. However, TACE is not satisfied with improving overall survival. Therefore, there is an urgent need for effective treatment for these patients. At present, the overall objective response rate (ORR) of single or sequential therapy is not satisfied, and the over survival (OS) improvement is not ideal. Therefore, combined therapy maybe the good choice for patients with advanced HCC. This study focuses on the in-operable, BCLC-B/C HCC patients. Through the combination of local therapy (TACE), anti-angiogenic therapy (Sorafenib), and immunotherapy (PD-1 monoclonal antibody), it is expected to change the tumor microenvironment, restore the immune response, strengthen the anti-tumor effect of various treatments, and improve the therapeutic efficacy in patients with BCLC-B/C HCC.

NCT04682847
There is a high prevalence of hepatic cirrhosis in patients with hepatocellular carcinomas (HCC), or chemotherapy-induced hepatic atrophy or hepatosteatosis in patients with liver metastases associated with high risk of radiation-induced liver disease (RILD) after stereotactic body radiotherapy (SBRT). MRI-SPION radiotherapy planning will facilitate detection and maximize avoidance of residual functionally active hepatic parenchyma from over-the-threshold irradiation thus increasing safety of liver SBRT in patients with pre-existing liver conditions. The investigators have previously demonstrated that liver SBRT with SPECT/CT functional treatment planning utilizing 99mTc sulfur colloid in transplant eligible patients associated with minimal hepatotoxicity and without hastening of advanced hepatic cirrhosis progression while patients await liver transplant. Switching from nuclear medicine to an MR-Linac-SPION based quantitative treatment-planning platform will substantially improve diagnostic accuracy in defining safe volumes of residual functional hepatic parenchyma for liver SBRT planning on MR-Linac.
NCT02571946
The standard treatment of advanced hepatocellular carcinoma (HCC) is sorafenib. Though the agent showed clear survival benefit in two randomized phase III trials, the benefit was modest and response rate was just a few percent. Therefore, other loco-regional modalities, like trans-arterial chemo-embolization (TACE), hepatic arterial infusion chemotherapy (HAIC), and radiotherapy (RT) were continuously tried, especially in locally advanced HCC including portal vein tumor thrombosis (PVTT). With the advancement of conformal RT techniques, RT was actively applied in HCC, especially in PVTT combined HCC. Many researchers reported that there is a relationship between RT dose and tumor response rate. RT dose, however, is frequently limited because the complications (like radiation induced liver disease (RILD), radiation induced gastro-duodenal toxicity, etc.) are also closely related with higher exposed RT dose. Proton beam has characteristic depth-dose distribution contrast to photon, the "Bragg peak". The advantage of this dose distribution could be more highlighted in HCC management, because of the weakness and maintenance importance of liver function itself in HCC patients. In fact, the superior results of proton beam therapy in HCC were constantly reported in several groups as prospectively as well as retrospectively. In those background, the investigators planned the present study to evaluate the efficacy and safety of proton beam therapy in HCC patients combined with PVTT.

NCT05495529
This study aims to analyse retrospectively the feasibility, the safety, and the efficiency, of biliary or digestive protection with room air interposition for thermal ablation of central liver tumors with high iatrogenic risk. Thermal ablation is a mini-invasive and curative treatement of liver tumors. However, it requires to be carefull about surrunding organs, such as digestive structures or central biliary tree, which can be injured if not insulated. The technique of gas interposition to protect adjacent gut is already known and validated with carbonic gas. Nevertheless, resorption of this gas is very fast, making its use tricky to keep a correct insulation during the whole thermal ablation process. Room air interposition is easy to use and can offer a slow resorption speed. Furthermore no datas are available concerning the use of room air whatever the organ protected, and the protection of central biliary tree whatever the gas used.
