The Primary and Secondary are listed below.
Primary Objective:
\- To evaluate progression free survival after modified FOLFIRINOX and SBRT in borderline resectable and locally advanced pancreatic cancer.
Secondary Objective:
* To evaluate the radiographic response to FOLFIRINOX and SBRT by comparing IV contrast CT scans before and after therapy.
* To determine rates of recurrence (local only, systemic only, and both local and systemic), and overall survival.
* To determine rates of grade 3 or greater gastrointestinal toxicity, including acute toxicities occurring within 3 months of treatment, and late toxicities occurring over 3 months after completion of radiation.
