LC Bead LUMI Radio-Opaque Embolic Beads to Detect and Characterize the Vascularity of Hepatic Tumors During Treatment With Transarterial Embolization (TAE) Alone or Combined With Thermal Ablation

Study Overview
=================
Brief Summary
-----------------
Background: Liver cancer begins in the cells of the liver. It can be treated with chemotherapy, radiation, or even a liver transplant. A less invasive treatment may be able to help some people with liver cancer. It is called percutaneous transarterial embolization (TAE). For TAE, a material is injected into blood vessels to block the blood flow that is feeding the tumor. Researchers want to test a new material for TAE that may shrink tumors and can be seen on x-ray and CT images. The embolization may sometimes be combined with thermal ablation, or cooking tumors with needles that deliver heat by electricity or microwave. Objective: To test an embolization material called an LC LUMI beads. To see if it can block blood vessels that provide blood to cancerous tumors and to see how the beads look on x-ray and CT images. Eligibility: Adults 18 85 years old who have been diagnosed with liver cancer Design: Participants will have routine blood tests, physical exams, and x-rays. Participants will be screened with blood tests, physical exam, and medical history. They will have a computed tomography (CT) scan of the abdomen and pelvis. This will include a contrast drink and a contrast (dye) injected in the veins. Participants will be admitted to the clinic. They will repeat the screening tests. Participants may have other tests. These may include x-rays, other scans, or ultrasound. Participants will be evaluated for general anesthesia. They will get counseling about the procedure. Participants will get anesthesia. The LC LUMI beads will be injected into blood vessels. The beads contain iodine, which makes them visible by x-ray and by a CT scan machine. Participants will have follow-up visits for 12 months. They will have CT scans and/or other radiologic tests.

Detailed Description
-----------------
Background: Hepatocellular Carcinoma (HCC) is the 3rd most common cause of cancer globally with an increasing incidence worldwide. Management of hepatic malignancies from primary Hepatocellular Carcinoma (HCC) or metastatic disease involves a multidisciplinary approach of surgery and chemotherapy and in the case of HCC, transplant, anti-VEGF sorafenib, or local or regional image guided therapies. Thermal ablation (RFA or MWA) and transarterial embolization (TAE) are minimally invasive image guided local or regional therapies that have been extensively studied for decades, and more recently and to a lesser extent have been studied together as a combination therapy. LC Bead LUM^TM, a radiopaque embolic bead product (company code BTG 13-002), is an imageable spherical embolic product that can be visualised by X-ray based imaging (e.g., fluoroscopy and CT). The beads are non-resorbable microspheres with calibrated size ranges that occlude arteries for the purpose of blocking the blood flow to a target tissue. LC Bead LUMITM are intended to be used for the embolization of hypervascular tumors and arteriovenous malformations (AVMs). Objectives: To determine the imaging characteristics of radiopaque beads including qualitatively comparing virtual and actual bead perfusion in the treatment of hepatic tumors using bead embolization. Eligibility: Treatment eligibility for TAE requires agreement between the Interventional Radiologist reviewing imaging and feasibility of TAE and the patient's NIH primary treatment team who will evaluate the patient's clinical parameters to undergo anesthesia and the TAE and or ablation procedure. At least >=18 years of age Patients with pathologically proven, hepatic-dominant neoplasm. The extent of hepatic metastases is <50% of total hepatic volume. Past treatment with Y90 must be 6 months from TAE treatment and liver function within NIH institutional limits ECOG performance status <=2 Patients must have normal organ and marrow function per laboratory parameters Patients with minor allergies to iodine will also be excluded. Design: Number of Participants: 30 Recruitment Time Frame: approximately 2 years Type of Study: Feasibility study This is a pilot study to assess the characteristics of radio-opaque bland beads during TAE in the treatment of hepatic malignancies. Patients may also receive thermal ablation treatment in conjunction with TAE if clinically indicated, although comparison of bead treatment with or without thermal ablation is not part of the study s aim. To compare virtual and actual perfusion characteristics of the LUMI radiopaque beads with CBCT and/or CT. Patients scans will be obtained per TAE standard of care schedule. Other imaging evaluation of this therapy may be performed at regular intervals following completion of treatment, and will be governed by standard conventional imaging regimen post treatment. The choice of which combination of imaging (CT, Cone beam CT (CBCT), or fluoroscopy) and when to image, will be made by the clinical care team for the patient, based upon multidisciplinary recommendations and NIH Clinical Center customary use and standard of care, and will be purely clinical decisions (not research-related). The participants will have a diagnosed hepatic malignancy, and be eligible to undergo transarterial embolization and thermal ablation under general anesthesia. The LC LUMI bead will be used in the transarterial embolization procedure. Follow up will continue for 12 months from the time of initial treatment. Patients will be evaluated in multidisciplinary GI medical oncology clinic and up to 30 patients will be enrolled to accrue 20 evaluable patients.

Eligibility Criteria
-----------------
INCLUSION CRITERIA: Patients who are determined to be eligible for TAE by an interventional radiologist and the primary/referring team will be eligible for the study. Patients with pathologically proven hepatic-dominant neoplasm that might otherwise be candidates for standard clinical TAE. Extent of hepatic metastases is <50% of total hepatic volume. At least >=18 years of age: Because it is exceeding rare for someone under the age of 18 to develop hepatocellular carcinoma, we will exclude patients <18 years of age, children are excluded from this study, but will be eligible for future pediatric trials. ECOG performance status 0-2 Six months since last treatment with Y90 Patients must have normal or adequate organ and marrow function as defined below: Hematology/Absolute Neutrophil Count/ > 1500 / mm3 without help of Filgrastim or other stimulating growth factors Hematology/Platelet Count Patient eligible if platelet count is correctable to >=50,000/mm3 Hematology/Hemoglobin Patient eligible if hemoglobin count is correctable to >= 8.0 g/dl Serum Chemistry/ALT/AST <= 5 times the upper limit of normal; except in the presence of obstructive liver metastases where ALT/AST may be up to 10 times the upper limit of normal Serum Chemistry/Creatinine <1.5x institution upper limit of normal OR creatinine clearance >= 45mL/min/1.73 m2 for patients with creatinine levels above institutional normal. Serum Chemistry/Total Bilirubin <=3 mg/dl Serum Chemistry/Prothrombin Time within 2 seconds of the upper limit of normal (INR<=1.8) Ability of subject to understand and the willingness to sign a written informed consent document. Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. EXCLUSION CRITERIA: No contraindications to receive iodine products. Main Portal Vein Occlusion or other contraindications to chemoembolization Patients taking immunosuppressive drugs or unable to come off of ongoing chronic anticoagulation will not be eligible. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection with systemic manifestations, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. Pregnant women and nursing mothers are excluded from this study because of the potential for teratogenic or abortifacient effects of required multiple imaging and associated radiation doses, anesthesia and risks during thermal ablation to the fetus. Enrolled patients must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately.
