Study of Gemcitabine and Oxaliplatin With Radiation Therapy in Patients With Pancreatic Cancer

This study will examine a sequence of treatments including pre-operative chemotherapy and
radiation, surgery and post-operative chemotherapy for resectable pancreatic cancer. This
research treatment will evaluate the combination of two chemotherapy agents, oxaliplatin and
gemcitabine with radiation therapy. The researchers have already done studies using
oxaliplatin, gemcitabine and radiation therapy together for pancreatic cancer. They want to
build on the information they have from this previous research and do the research at
multiple sites. They will use this study to determine how well people do who are treated
with gemcitabine, oxaliplatin, and radiation therapy prior to having surgery for their
pancreatic cancer. The researchers will also gather more information about what type of side
effects occur with this treatment.

Inclusion Criteria:

- Patients must have cytologic or histologic confirmation of carcinoma arising in the
pancreas.

- Patients must be deemed resectable or borderline resectable based on criteria in
section 4.2 prior to registration.

- Patients must have an expected life expectancy of at least 12 weeks and a Zubrod
performance status of < 2.

count of > 1500/mm3, platelets > 100,000/mm3, serum Cr < 1.5 mg/dl, total bilirubin <
3.0 mg/dl with relief of biliary obstruction if present (PTC tube or endobiliary
stent).

- Patients must be free of other active systemic malignancy, ongoing infection,
including HIV infection, or any other serious uncontrolled, concomitant systemic
disorders or psychiatric condition that would interfere with the safe delivery of
protocol therapy.

- Patients must be aware of the investigational nature of the therapy and provide
written informed consent.
