Proton Therapy and Bevacizumab for Primary Liver Tumors
- To evaluate the safety of the treatment of patients with technically or medically inoperable hepatocellular carcinoma and cholangiocarcinoma with proton therapy and concurrent bevacizumab biotherapy.
- To identify the maximum tolerated dose (MTD) using this combination.
- To evaluate local control rate within the radiation field, hepatic control rate outside the treatment field, time to radiographic progression and 2 year survival rate.
- To analyze dose-volume characteristics that influence the development of radiation induced liver disease (RILD) and GI bleeds that may occur.
- To assess quality of life during and after chemoradiation therapy.

3 Gy dose/fraction x 20 fractions.
Proton beams are designed to deliver a high dose of radiation to the abnormal tissues while sparing surrounding normal tissues. Bevacizumab is a biotherapy that is designed to prevent or slow down the growth of cancer cells by blocking the growth of blood vessels.
Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have a complete physical exam. Blood (about 2 tablespoons) and urine will be collected for routine tests. You will have chest x-rays and a computed tomography (CT) scan of your abdomen (stomach area) and pelvis. Women who are able to have a children must have a negative urine pregnancy test.
You will then have a radiation treatment planning session called a simulation. You will get a CT scan of your abdomen, and marks will be placed on your skin to help guide the radiation treatments when you return for the actual treatments. At around the same time, you will receive your first dose of bevacizumab through a needle in your vein. The infusion will at first last 90 minutes. If there are no allergic reactions, fevers, or chills, the infusion will be shortened to 60 minutes and then 30 minutes for later infusions. Your second dose of bevacizumab will be given with the start of radiation therapy treatments. Your final dose of bevacizumab will be given 2 weeks later. You will receive radiation therapy once a day, for 5 days in a row (Monday-Friday) for 4 weeks (total of 20 treatments).
During this study, you will have physical exams weekly during treatment, 1 month after the last proton beam therapy visit and then every 3 months thereafter. Every week, while receiving proton beam therapy, blood (about 2 teaspoons) will be drawn to check for any side effects. You will be asked about any side effects you may be experiencing.
You may remain on study for as long as you are benefitting. You will be taken off study if the disease gets worse or intolerable side effects occur.
After participation in this study is over, you will have follow-up evaluation every 3 months for 2 years. During these visits, you will have a physical exam. You will have CT scans. Blood (about 2 teaspoons) will be drawn for routine tests.
This is an investigational study. Bevacizumab is FDA approved and commercially available for the treatment of metastatic colon cancer. The use of bevacizumab with proton beam therapy is investigational. Up to 30 patients will take part in this study. All will be enrolled at M. D. Anderson.
