Extension of Liver Transplantation Opportunity to Patients Suffering From Milan-out, Up-to-7-in, Hepatocellular Carcinoma: a Prospective Belgian Study of the Value of Negative 18FDG PET/CT

Hepatocellular carcinoma (HCC) is a rising public health concern with few curative options but liver transplantion (LT) in highly selected cases. LT could save many other HCC patients but organ shortage has lead to the necessity of selection of patients with the best survival chances, namely the Milan criteria. Hepatocellular carcinoma (HCC) is the fifth most common cancer, and the third cause of cancer related-death worldwide. HCC incidence is rising in Western countries including Belgium. There are more than 1,000 new HCC diagnoses in Belgium every year, but only 90 to 100 patients suffering from HCC are listed for liver transplantation (LT). In fact, the scarcity of organ donors has forced the development of strict criteria to limit LT to patients who are likely to have excellent outcomes. The universally accepted LT criteria for HCC are the Milan criteria (1 HCC nodule ≤5 cm or 3 nodules ≤3cm) that lead to a low rate of post-LT recurrence (>80% of disease free recurrence at 5 years). The majority of patients suffering from HCC outside the Milan criteria at the time of diagnosis is not eligible for LT and is therefore limited to palliative care. It is however considered that some of these patients with HCC outside the Milan criteria may benefit from LT with an acceptable risk of recurrence and chances of long-term disease-free survival (DFS). This fact has led to the extension of LT criteria for HCC in some centres in different countries, as for example the University of California San Francisco (UCSF) criteria, the up-to-seven criteria or the Asan criteria.

Optimizing Outcomes of Patients With Advanced HCC Undergoing Immunotherapy Through Novel 68Ga PSMA PET Imaging

This phase II trial tests whether 68-Gallium prostate specific membrane antigen (68Ga-PSMA) positron emission tomography (PET) imaging can improve the diagnosis and management of liver cancer that has spread to other parts of the body (advanced). PSMA is a protein that appears in large amounts on the surface of liver cancer cells. The radioactive chemical compound (68Ga-PSMA) has been designed to circulate through the body and attach itself to the PSMA protein on liver cancer cells. A PET scan is then used to detect the location of the tumor cells. 68Ga-PSMA PET may improve upon the diagnosis and management of liver cancer.

NCT06123676

Introduction to the Clinical Workflow of Y90-PET-CT Post-therapy Scans to Patients Undergoing Y90-microspheres Radioembolisation Therapy

Yttrium-90, attached to microspheres, usually referred to as 90Y-microspheres or Y-90 radioembolisation, can be used in some cases to treat patients with liver tumours or liver metastasis. The treatment aim is to infuse the 90Ymicrospheres into the patient's liver. The microspheres get trapped in the lesions of micro-blood vessels while the yttrium-90, a radioactive compound, delivers radiation doses locally at these sites and damages the diseased cells. Therapy is performed in such a way the 90Y-microspheres are localised in the tumour areas minimising damage to the healthy liver tissue. This treatment requires many steps involving professionals from different medical disciplines. Patients are scanned in the nuclear Medicine Department on a gamma camera the day after the treatment. This scan is referred as Y-90 bremsstrahlung-SPECT. This posttherapy scan provides a 3-dimensional (3D) image of the distribution of the therapeutic agent in the patient's abdomen so an assessment of how much of the therapeutic agent has gone to the sites of disease can be performed. In this research project, the investigators would like to evaluate an alternative post-therapy scan to the one routinely performed on the gamma camera. The alternative scan is done on a PET-CT scanner and is referred to as Y90-PET-CT. This type of scan has been reported to provide improved quality images, providing more accurate information on the distribution of the patients therapeutic dose. For this research project, the investigators will invite a small number of patients undergoing this therapy to be scanned twice after treatment: with the current post-therapy scan on a gamma camera; and with the newly proposed scan method, Y90-PET-CT. Depending on the outcomes of this project, assessed by an expert panel of radiologists and medical physicists, the investigators will determine whether we will introduce this new scanning method into clinical practice in the future.

NCT06327269

Innovative Diagnosis and Therapy in LDLT Patients With High-risk Hepatocellular Carcinoma

The challenge of LDLT to HCC is that tumors with a high risk of recurrence have a high rate of recurrence after liver transplantation, and there is no appropriate treatment to prevent HCC recurrence after transplantation in these patients. Using the advance proton therapy or yttrium 90 as a more aggressive down-staging therapy may contribute to change tumor behavior. It can be used to get a better treatment response and tumor necrosis before LDLT. As a result, it will improve recurrence-free survival and overall survival rate, especially in high-risk groups. In addition, lenvatinib is approved for using in patients with advanced liver cancer because its overall survival rate is not less than sorafenib in clinical trials. A new generation of targeted therapies will be applied to adjuvant therapy after LDLT.

NCT03457948

A Pilot Study of Pembrolizumab and Liver-Directed Therapy or Peptide Receptor Radionuclide Therapy for Patients With Well-Differentiated Neuroendocrine Tumors and Symptomatic and/or Progressive Metastases

This pilot phase II trial studies how effective pembrolizumab and liver-directed therapy or peptide receptor radionuclide therapy are at treating patients with well-differentiated neuroendocrine tumors and symptomatic and/or progressive tumors that have spread to the liver (liver metastases). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Liver-directed therapies such as radiofrequency ablation, transarterial embolization, yttrium-90 microsphere radioembolization, and cryoablation may help activate the immune system in order to shrink tumors that are not being directly targeted. Peptide receptor radionuclide therapy is a form of targeted treatment that is performed by the use of a small molecule, which carries a radioactive component attached to a peptide. Once injected into the body, this small molecule binds to some specific sites on tumor cells called receptors and emit medium energy radiation that can destroy cells. Because this radionuclide is attached to the peptide, which binds receptors on tumor lesions, the radiation can preferably be targeted to the tumor cells in order to destroy them. Giving pembrolizumab in combination with liver-directed therapy or peptide receptor radionuclide therapy may work better than pembrolizumab alone.

NCT04762888

Early Detection, Accurate Staging, and Biologic Characterization of HCC With Hybrid 68Ga-PSMA-Dual -Contrast PET/MRI and PET/CT Using Cyclotron-Produced 68Ga

This phase II trial studies how well 68Ga-PSMA PET/MRI or PET/CT works in early detection of liver cancer. 68Gallium-PSMA is a radioactive tracer designed to circulate through the body and attach itself to the prostate- specific membrane antigen (PSMA) protein on liver cancer cells. Magnetic resonance imaging (MRI) is a scan that uses magnetic and radio waves to produce detailed structural information of the organs, tissues, and structures within the body. Positron emission tomography (PET) is an imaging test that helps to measure the information about functions of tissues and organs within the body. A PET scan uses a radioactive drug (tracer) to show this activity. Computed tomography (CT) scan uses X-rays to create images of the bones and internal organs within your body. Combining a PET scan with an MRI or CT scan may help make the images easier to interpret. This trial may help determine if 68Ga- PSMA PET/MRI or PET/CT can improve upon the diagnosis and management of liver cancer in the future.

PET Imaging of Tumors in Pancreas, Bile Ducts, Stomach and Ovaries by a Novel Tracer, 68Ga-FAPI-46 = Fibroblast Activation Protein Inhibitor

Cancers of the pancreas, bile ducts, stomach and ovaries are dismal diseases with most patients being diagnosed in advanced stages leading to a bad prognosis. These cancers can be difficult to diagnose and sometimes impossible to differentiate from underlying benign conditions. Establishing the correct diagnosis of primary cancer lesions and possible spread to other organs in time is pivotal for choosing the right therapy. Routinely applied staging procedures are however not always reliable. The main aim in this study is to evaluate the diagnostic accuracy of PET/CT with a novel radiotracer, FAPI, in the primary diagnosis of cancers in the pancreas, stomach and bile ducts as well as in patients with primary and recurrent epithelial ovarian cancer (EOC).

NCT04459273

PET Biodistribution Study of 68Ga-FAPI-46 in Patients With Different Malignancies: An Exploratory Biodistribution Study With Histopathology Validation

This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.

NCT04792801

Evaluation of PET TDM FDG-Choline as a Decision-making Tool for Routine Care on Inclusion on the Liver Transplant List for Hepatocellular Carcinoma

HCC is the most common malignant liver tumor for which liver transplantation is one of the pivotal curative treatments. The best possible selection of patients who are candidates for transplantation is essential in the current context of a shortage of transplants. Performing a PET CT scan is not currently recommended in the pre-liver transplant workup for HCC. However, PET CT using in a complementary manner the FDG and Choline tracers appears promising in the management of HCC in view of its wide use in oncology and its major diagnostic and prognostic contribution compared to conventional imaging. In order to address this issue, a prospective cohort study including patients from the University Hospital of Rouen and Lille with hepatocellular carcinoma meeting the criteria for indication of liver transplantation validated in SPC will be set up, the main objective of which will be to assess the decision-making contribution of PET TDM FDG and Choline in addition to conventional imaging in the pre-transplant assessment.
