Summary
RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as gemcitabine, oxaliplatin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving bevacizumab together with combination chemotherapy and radiation therapy may kill more tumor cells. PURPOSE: The phase II trial is studying the side effects and how well giving bevacizumab together with gemcitabine, oxaliplatin, fluorouracil, and radiation therapy works in treating patients undergoing surgery for locally advanced pancreatic cancer.

Criteria
DISEASE CHARACTERISTICS:

- Histologically confirmed adenocarcinoma of the pancreas

- Resectable, marginally resectable, or unresectable disease determined by one of
the following:

- Contrast-enhanced helical-CT scan

- Endoscopic ultrasound with biopsy (in patients who do not have metastatic or
grossly unresectable disease)

- Dedicated pancreatic MRI

- Tumor must be locally advanced or potentially resectable, as determined by one of
the following:

- Abutment of the portal or superior mesenteric veins, hepatic or superior
mesenteric artery

- Extension to the origin of gastroduodenal artery

- Occlusion of the superior mesenteric vein for < 2 cm

- Measurable disease, defined as ≥ 1 lesion that can be accurately measured in ≥ 1
dimension (longest diameter to be recorded) as ≥ 20 mm by conventional techniques or ≥
10 mm by spiral CT

- Marker elevation alone not allowed as justification for study entry

- Formalin-fixed, paraffin-embedded tumor tissue specimens from prior biopsy or surgical
resection allowed for correlative studies

- No known brain metastases or tumor metastatic to the peritoneum, liver, or other
organs

PATIENT CHARACTERISTICS:

- ECOG performance status 0-1

- ANC ≥1,500/mm³

- Platelet count ≥ 100,000/mm³

- AST and ALT ≤ 2.5 times upper limit of normal (ULN)

- Creatinine < 1.5 times ULN

- Bilirubin < 2.0 mg/dL (≤ 10 mg/dL for patients with biliary obstruction by tumor)

- A biliary stent ≥ 9F or biliary bypass is required before treatment if there is
biliary obstruction by tumor

- Urine protein:creatinine ratio ≤ 1.0

- Not pregnant or nursing

- Negative pregnancy test

- Fertile patients must use effective contraception

- No significant traumatic injury within the past 28 days

- No serious non-healing wounds, ulcers, or bone fractures

- No abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within
the past 6 months

- No myocardial infarction, unstable angina, or cerebrovascular accident within the past
6 months

- No NYHA class II-IV congestive heart failure

- Class II defined as symptoms of fatigue, dyspnea or other symptoms with ordinary
physical activity

- No clinically significant peripheral vascular disease

- Pre-existing hypertension allowed, provided that the patient is receiving a stable
antihypertensive regimen and has a blood pressure ≤ 150/100 mm Hg at the time of
enrollment

- Must have adequate oral intake of > 1500 calories/day and be able to maintain
hydration OR have access for supplemental enteral feeding (nasoenteral tube, feeding
jejunostomy, or percutaneous endoscopic gastrostomy tube)

PRIOR CONCURRENT THERAPY:

- No prior chemotherapy or radiotherapy for pancreatic cancer

- More than 28 days since prior and no anticipated need for concurrent major surgical
procedures

- More than 7 days since prior minor surgical procedures such as laparoscopy, fine
needle aspirations, or core biopsies

- No treatment plan requiring treatment of > 50% of the liver at a dose > 30 Gy or > 50%
of the total kidney volume at a dose > 18 Gy

- No concurrent combination antiretroviral therapy for HIV-positive patients

- No other concurrent investigational agents

- No oral or parenteral anticoagulation unless patients is receiving a stable dose of
anticoagulant
