Brief summary: This study is evaluating stereotactic radiosurgery (CyberKnife) plus chemotherapy for the treatment of potentially resectable adenocarcinoma of the pancreas

Detailed description: This study is evaluating the role of neoadjuvant chemotherapy and CyberKnife therapy in increasing the number of patients who are able to successfully undergo definitive surgical management of their pancreatic carcinoma. In addition, we will evaluate the associated therapeutic toxicities and gather data regarding the quality of life indicators at similar time intervals for an improved overall assessment of the effects of this course of treatment on our patients.

Surgery is deemed the only curative technique for pancreatic cancer. Unfortunately, more than 80% of patients who present with the disease cannot be cured by resection.

The literature reports median survival for resectable patients on the order of 19 months, with a 20% 5 year survival rate. For patients unable to undergo surgical resection, the median survival in the literature is approximately 11 months. In the absence of the proposed protocol, this patient population would be treated as per the standard of care for locally advanced non-metastatic surgically unresectable pancreatic malignancies, which would include a combination of chemotherapy and radiation therapy. The anticipated Grade 4 and above toxicity would be approximately 3-5% from this regimen. The rate of G 4 and above toxicity is not known with the use of this neoadjuvant regimen, and, therefore, this constitutes the major risk associated with this protocol therapy. The associated benefit, however, is the anticipated improvement in median survival that these patients may derive from the ability to successfully undergo surgical resection. A secondary proposed benefit is the potential for reduction in the treatment associated toxicity with this altered multimodality schedule when compared to traditional multimodality care or non-surgical care of locally advanced pancreatic malignancy.

Eligibility criteria: Inclusion Criteria:

* Pathologically confirmed adenocarcinoma of the pancreas
* Resectable or potentially resectable disease based on the following imaging criteria performed \< 4 weeks from study entry and as determined by local review (Cooper radiologist)

* Life expectancy \> 3 months
* Ability to understand and the willingness to sign a written informed consent.

Exclusion Criteria:

* Inability to undergo MRI with contrast for treatment planning
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
* Patients may not be receiving any other investigational nor commercial agents with therapeutic intent to treat pancreatic cancer while on this trial.
* unresectable pancreatic cancer based on the following imaging criteria performed \< 4 weeks from study entry and as determined by local review (Cooper radiologist)
