The purpose of this phase 2 research study is to determine whether a combination of chemotherapy drugs plus radiation therapy, given before surgery in resectable pancreactic cancer, can help to increase the chances of surgeons achieving and R0 resection. The chemotherapy drugs used are gemcitabine and nab-paclitaxel. These drugs are both approved by the FDA for use in treating adults with pancreatic adenocarcinoma. The investigational portion of this study is providing the chemotherapy drugs and radiation therapy before surgery. Primary Endpoint, R) resection rate ≥70%. Secondary Endpoints, Disease free survival, Overall survival , Perioperative mortality and morbidity.


Primary Endpoint: R0 resection rate ≥ 70%

Secondary Endpoints: Disease free survival, Overall survival, Perioperative mortality and morbidity

Treatment should start within 28 days of registration. Pre-operative Chemotherapy Patients will receive a combination of the agents (gemcitabine and nab-paclitaxel) prior to surgery for a maximum of four cycles.

Gemcitabine 1000 mg-m2 IV on days 1, 8, 15 Nab-paclitaxel 125 mg-m2 IV on days 1, 8, 15 28 day cycles

Post-operative Chemotherapy Treatment should start within 5-10 weeks of surgery. Patients will receive a combination of the agents (gemcitabine and nab-paclitaxel) after surgery for maximum of two cycles.

Gemcitabine 1000 mg-m2 IV on days 1, 8, 15 Nab-paclitaxel 125 mg-m2 IV on days 1, 8, 15 28 day cycles

Radiation Therapy Immobilization and Treatment Planning CT Scan All patients will be immobilized in a full body immobilization device in the supine position.

A 4D-CT scan from T5 to L5-S1 with intravenous and oral contrast will be performed.

Radiation Toxicity All acute toxicities will be scored according to the NCI Common Toxicity Criteria v4.0. Late toxicity will be scored per RTOG guidelines.

Surgery, Pre-operative Re-staging Pre-operative evaluation should occur within 2-4 weeks prior to the planned surgery date. Based on the results of the pre-operative evaluation, the corresponding action below should be taken.

Radiological responding or stable disease: Patients should proceed to surgery per protocol.

Surgery Pancreatic resection should occur within 4-10 weeks after the last dose of preoperative chemotherapy or SBRT. Staging laparoscopy may be performed at the time of planned laparotomy but is not required.

Post-operative Restaging Evaluation should occur within 2 weeks prior to initiation of postoperative chemotherapy.

Tumor Response Evaluation (Adapted From RECIST 1.1) Assessment of overall tumor burden and measurable disease To assess objective response or future progression, it is necessary to estimate the overall tumor burden at baseline and use this as a comparator for subsequent measurements. Only patients with measurable disease at baseline should be included in protocols where objective tumor response is the primary endpoint. Measurable disease is defined by the presence of at least one measurable. In studies where the primary endpoint is tumor progression (either time to progression or proportion with progression at a fixed date), the protocol must specify if entry is restricted to those with measurable disease or whether patients having non-measurable disease only are also eligible.
