Fusion Guided Thermal Ablation Combined With External Beam Radiation for Hepatic Neoplasms

Phase 1TerminatedNCT01862718

National Institutes of Health Clinical Center (CC)5 enrolled

Overview

Background: Pilot study to assess feasibility for combining treatment modalities that should be synergistic (radiation and thermal ablation). Thermal ablation with Radiofrequency Ablation (RFA) and microwave ablation (MWA) are standard treatments for focal neoplasms in the liver. High volume or scattered locations of tumor burden results in inability to successfully use this technology for a large proportion of patients with hepatic neoplasms. Methods to enhance treatment volumes could be advantageous in potentially increasing the indications for thermal ablation or the number of patients benefitting from local ablation. Primary objective: To determine the safety of combining 2 standard therapies (thermal ablation and external beam radiation therapy) for liver neoplasms up to 10 cm diameter. Eligibility: Patients greater than 18 years of age with pathologically proven unresectable primary or metastatic hepatic neoplasms Patients whose extent of hepatic metastases represents approximately less than 60% of total liver volume AND whose extrahepatic metastatic disease is determined to be minimal ECOG performance status of less than or equal to 2 and a life expectancy of more than 3 months Patients with a history of chemotherapy, radiation therapy, or biological therapy for at least 4 weeks prior to starting study treatments, and 4 weeks after treatments Patients must not have an acute, critical illness If clinical or imaging evidence for cirrhosis present, then Bilirubin must be less than 3 mg/dl and Child-Pugh Classification A, (Class B \& C are excluded) Design: Patients will undergo external beam radiation as well as thermal ablation according to standard operating procedures of the NCI and NIH CC. Patients will be monitored using the standard imaging studies when clinically warranted. Patients may be treated with a second (or more) thermal ablation procedure ALONE if it is deemed beneficial for the patient by the investigator. The sample size will be 10 evaluable patients

* INCLUSION CRITERIA: Patients with hepatic-dominant neoplasms where the life limiting component of the disease is hepatic neoplasms Patients hepatic lesions must be considered technically unresectable or that their overall health makes surgery inadvisable Have 5 or fewer lesions and with no single lesion greater than 10 cm in maximum diameter Patients with extrahepatic neoplasms or an unresected primary lesion will be considered eligible if the extrahepatic disease is minimal and stable Serum Creatinine less than or equal to 2.0 mg/dl unless the measured creatinine clearance is greater than 60 ml/min. Absolute neutrophil count (ANC) greater than or equal to1500/m3 without help of Filgastim, hemoglobin greater than 8 g/dL, and platelet count greater than or equal to 75,000 m3 Bilirubin less than 3 mg/dl, and AST and ALT less than 5 X upper limit of normal except in the presence of obstructive liver neoplasms where ALT/AST may be up to 10 X the upper limit of normal. Prothrombin Time (PT) within 2 seconds of the upper limit normal (INR less than or equal to 1.5) Patient on oral, SQ or IV anticoagulants will be expected to have an abnormal PT and will be considered eligible if they can safely dicontinue the anticoagulant before ablation. A repeat PT will be obtained at least 24 hours prior to the radiofrequency ablation (only) and should be within practice safety guidelines of an INR less than 1.5 or if greater than 1.5 have clinical reversal agent as appropriate to the anticoagulant administered. Extent of hepatic neoplasms is approximately less than 60% of total hepatic volume Patients must have pathology proof of neoplasm. If proof of pathology is unavailable, histopathological confirmation of liver neoplasm may not be requisite in the setting of clinical or radiological characteristics that are highly suggestive of a neoplastic diagnosis, with such designation determined by PI and a medical or surgical oncologist, with the NCI multidisciplinary gastrointestinal tumor board review, in the event of absence of such consensus. Patients referred for ablation or radiation of liver neoplasm ECOG performance status less than or equal to 2 Life expectancy greater than 3 months At least 18 years of age Age less than 85 years Patients must have had no chemotherapy, radiotherapy, or biologic therapy for their malignancy for at least 28 days prior to treatment and must have recovered from all clinically significant side effects of therapeutic and diagnostic interventions. EXCLUSION CRITERIA: Portal Vein Occlusion or other contraindications to thermal ablation or radiation Prior selective internal radiation therapy (SIRT) with Yttrium-90 or prior radiation to the liver Prior biliary diversion surgery Patients with active bacterial infections with systemic manifestations (malaise, fever, leukocytosis) are not eligible until completion of appropriate therapy. Any exclusion criteria for radiation or for ablation, such as ataxia telangiectasia, active connective tissue disease, or inflammatory bowel disease, or other known conditions which predispose to radiation toxicities Patients with an acute, critical illness Pregnant women are excluded from the study. Patients are excluded from pregnancy testing if they are above the childbearing age of 55 years old, or if they have documented history of infertility or acquired or congenital disorders incompatible with pregnancy or if the patient has had a hysterectomy or bilateral oophorectomy. Patients are also excluded from pregnancy testing if they are at least 50 years of age AND have not menstruated for at least 12 months OR have a documented Follicle Stimulating Hormone (FSH) level of greater than 40 mIU/mL.
