This phase I/II trial studies the side effects and how well nivolumab, fluorouracil, and interferon alpha 2b work for the treatment of fibrolamellar cancer (liver cell cancer) that cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Interferon alpha 2b may help stimulate the immune system to fight cancer. Giving nivolumab, fluorouracil, and interferon alpha 2b may work better in treating unresectable fibrolamellar cancer compared to fluorouracil and interferon alpha 2b alone.
Eligibility criteria
Qualifiers
Patients, or their legal guardian, must give written informed consent prior to initiation of therapy, and patients under age 18 must give assent in keeping with the policies of the institution. Patients with a history of major psychiatric illness must be judged able to fully understand the investigational nature of the study and the risks associated with the therapy
Patients with histologically confirmed FLHCC (or with documentation of original biopsy for diagnosis is acceptable if tumor tissue is unavailable). The determination of resectability status will ultimately lie in the clinical judgment of the surgical oncologist and medical oncologist involved in the care of the patient. The definition of resectability is as follows: hepatectomy can achieve a negative margin while preserving more than 30% of the total estimated liver volume, sparing two contiguous hepatic segments, and maintaining vascular inflow, vascular outflow, and biliary drainage. Patients with extrahepatic disease are defined as having unresectable disease
Patient must have measurable disease defined as a lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) and measures >= 15 mm with conventional techniques or >= 10 mm with more sensitive techniques such as magnetic resonance imaging (MRI) or spiral computed tomography (CT) scan
Eastern Cooperative Oncology Group performance status (ECOG PS =< 1), or for patients under age 18 Karnofsky performance status of >= 70
Disqualifiers
Any other malignancy from which the patient has been disease-free for less than 2 years, except for non-melanoma skin cancer, or in situ carcinoma of any site
Patients who have organ allografts
Patients who have had a major surgical procedure, open biopsy, or significant traumatic injury with poorly healed wound within 6 weeks prior to first dose of study drug; or have an anticipated need for major surgical procedure during the course of the study (other than defined by protocol). NOTE: Patients will be allowed to start cycle 1 day 1 therapy after 24 hours from pre-treatment biopsy
Autoimmune disease: patients with a history of inflammatory bowel disease (including Crohn's disease and ulcerative colitis) are excluded from this study as are patients with a history of autoimmune disease (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune vasculitis [e.g., Wegener's granulomatosis])
