The purpose of this study is determine the safety of bevacizumab, oxaliplatin, 5-FU, and gemcitabine in combination with external beam radiation therapy(Phase I portion) as well as to begin to collect information about whether this combination treatment is effective in treating patients with locally advanced pancreatic cancer (Phase II portion).
- The combination of all three drugs and radiation treatment has never been given to people before, therefore, we are going to add just one additional drug at a time for safety reasons.
- The first group of participants (3-4) who enroll on the study will receive 5-FU, radiation therapy with the added drug oxaliplatin, this is called Regimen level 1. If these participants have few or easily manageable side effects, then another group of participants will be enrolled and will receive 5-FU, radiation, oxaliplatin with the addition of bevacizumab this is called Regimen level 2.
- The combination of study drugs and radiation will last about 6 weeks, this 6 week period is called a cycle 1.
- Regimen Level 1 will receive the following: oxaliplatin intravenously on days 1, 8, 15, 22, 29, and 36; 5-FU infused by a continuous infusion on days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-38; radiation therapy Monday-Friday to complete on day 38.
- Regimen Level 2 will receive the following; bevacizumab intravenously on days 1, 15, and 29; oxaliplatin intravenously on days 1, 8, 15, 22, 29 and 36; 5-FU infused by continuous infusion days 1-5, 8-12, 15-19, 22-26, 29-33, and 36-38; radiation therapy Monday-Friday to complete on day day 38.
- The following are tests and procedures that will be performed during cycle 1: physical examination; blood work, urine sample. perfusion CT scan on day 12 (for those participants enrolled at Massachusetts General Hospital).
- At the end of cycle 1, CT scans will be performed to evaluate the participants disease status before they receive combination gemcitabine and bevacizumab. If the scans show the tumor has reduced in size and can be surgically removed, then surgery will be scheduled and the patient will receive gemcitabine and bevacizumab about 4 weeks after the surgery. If the scans show the tumor can not be removed, the patient will receive the gemcitabine/bevacizumab combination about 4 weeks after completing cycle 1.
- Cycles 2-5 consist of: gemcitabine given intravenously on days 1, 8, and 15 every 28 days; bevacizumab given intravenously on days 1 and 15 every 28 days. During cycles 2-5 the following tests and procedures will be performed: physical examination including vital signs on day 1 and 15 of each cycle; blood work on days 1, 8 and 15 of each cycle; a urine sample on day 1 of each cycle; CT scans will be done every 2 cycles.
- It will take about 7 months to complete the study treatment (longer for those who have surgery after Cycle 1).

To assess progression-free survival of patients with locally advanced pancreatic cancer who are treated with concurrent gemcitabine, 5-FU, cetuximab and external beam radiation therapy.
RATIONALE: Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and he...

To evaluate the effectiveness of low dose external beam radiation therapy to halt progression of localized periocular light chain (AL) amyloidosis, a clonal plasma cell disorder.
We analyzed factors associated with rectal toxicity after iodine-125 prostate brachytherapy (BT) with or without external beam radiation therapy (EBRT).

Hyperammonemia is a rare adverse effect of 5-fluorouracil (5-FU) therapy, but can be very serious, even fatal. Physicians must be aware that hyperammonemic encephalopathy sometimes develops as an adve...
The use of an external beam of PROTONS as radiotherapy.
An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
