Study Overview
Brief Summary
This research protocol will evaluate the feasibility of administering neoadjuvant gemcitabine and nab-paclitaxel with hypofractionated, image guided, intensity modulated radiotherapy (HIGRT) in resectable and borderline resectable pancreatic cancer
Detailed Description
Pancreatic cancer is the fourth leading cause of cancer-related death in the United States and accounts for roughly 40,000 deaths each year. Despite the use of neoadjuvant and adjuvant therapies, little progress has been made in the the last three decades, and the search for more efficacious treatment continues.In patients with a good performance status the combination of effective systemic therapy with gemcitabine/nab-paclitaxel and high dose local radiotherapy may improve disease outcomes. This is a prospective, single arm study in patients in newly diagnosed, previously untreated pancreatic cancer who are planned to undergo surgical resection The primary objective of this study is to evaluate the toxicity of a neoadjuvant approach incorporating gemcitabine/nab-paclitaxel and Hypofractionated image guided intensity-modulated radiotherapy (HIGRT) prior to surgical resection. Eligible subjects will recieve standard neoadjuvant gemcitabine and nab-paclitaxel dosing is as follows:Nab-Paclitaxel (125mg/m2) days 1,8,15 every 28 days for 2 cycles Gemcitabine (1000mg/m2) days 1,8,15 every 28 days for 2 cycles followed by HIGRT and surgical resection.
Adjuvant chemotherapy may be given post surgery at the discretion of the treating medical oncologist.

Arms & Interventions
Chemotherapy/radiation/surgery
This is a single arm prospective study. All eligible subjects will recieve 2 cycles of neoadjuvant Gemcitabine/nab-Paclitaxel, followed by hypofractionated radiation therapy followed by surgical resection. Subjects may receive adjuvant chemotherapy post surgical resection at the clinical discretion of the medical oncologist.
Intervention: Gemcitabine/nab-Paclitaxel (Drug)
Chemotherapy/radiation/surgery
This is a single arm prospective study. All eligible subjects will recieve 2 cycles of neoadjuvant Gemcitabine/nab-Paclitaxel, followed by hypofractionated radiation therapy followed by surgical resection. Subjects may receive adjuvant chemotherapy post surgical resection at the clinical discretion of the medical oncologist.
Intervention: Radiation therapy (Radiation)

Subjects may receive adjuvant chemotherapy post surgical resection at the clinical discretion of the medical oncologist.
Intervention: Sugical resection (Other)

Outcomes
Primary Outcomes
Feasibility as Measured by Number of Participants Who Complete the Neoadjuvant Gemcitabine/Nab-paclitaxel and HIGRT Regimen
Time Frame: approximately 6 months
The neoadjuvant regimen will be considered feasible if (a) the trial can accrue 25 patients in no more than 3 years and (b) if at least 17 of the 25 patients adhere to the neoadjuvant regimen and c) the acute grade 3+ non-hematologic acute toxicity is less than 50% (exclusing fatigue and alopecia).
Secondary Outcomes
- Number of Participants Experiencing Grade >/=2 Acute Toxicity(60 days post surgery)
- Number of Participants Who Underwent Surgical Resection(14-30 days post surgery)
- Number of Participants Who Received an R0 Resection(14-30 days post surgery)
