Eligibility Criteria
-----------------
Inclusion Criteria: ≥ 18 years old at the time of informed consent Able to provide written informed consent and HIPAA authorization ECOG performance status of 0 or 1 Patient must be eligible for abdominal surgery Histologically confirmed adenocarcinoma of the pancreas that has been documented to be resectable by standardized radiographic criteria by a pancreatic surgeon Patients must to have tumor tissue collected prior to enrolling on this trial. Up to 10 patients will be accepted with no pre-treatment research tissue collection or tissue collection from an outside institution. a.If the tissue is from an outside institution, it must be reviewed at Indiana University Health Pathology Department if a biopsy was performed outside of this institution. Women of childbearing potential definition (WOCBP) must have a negative serum or urine pregnancy test performed within 14 days prior to initiation of FOLFIRINOX. Any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) is classified as WOCBP if she meets the following criteria: Has not undergone a hysterectomy or bilateral oophorectomy; or Has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months). WOCBP and men must agree to use adequate contraception prior, to study entry, for the duration of study participation, and 8 weeks after the end of treatment. Patients must have adequate organ function as defined by the following laboratory values at study entry: Hemoglobin ≥ 9 g/dL (transfusions are acceptable) ANC ≥ 1.5 x 109/L Platelets ≥ 100 x 109/L Creatinine ≤ 1.5 x ULN, or creatinine clearance ≥ 50 mL/min (estimated by Cockcroft-Gault or measured) Total bilirubin ≤ 1.5 x ULN AST/ALT ≤ 3 x ULN Exclusion Criteria: Prior therapy for pancreatic adenocarcinoma Other malignancies within the past 3 years except for the following: adequately treated cervical or vulvar carcinoma in situ, treated basal cell or squamous carcinoma of the skin, superficial bladder tumors (Ta, Tis & T1), ductal carcinoma in situ (DCIS) of the breast and low grade prostate cancer. Any cancer curatively treated >3 years prior to entry with no clinical evidence of recurrence is permitted. Hypersensitivity to 5FU, oxaliplatin (or other platinum agents), irinotecan (or to their excipients). Participation in any investigational drug study within 4 weeks preceding the start of study treatment. Patients are not permitted to participate in another investigational drug study while being treated on this protocol. Inability to receive a port or PICC line. History of or suspected Gilbert's Disease (testing not required if presence is not suspected). Baseline peripheral neuropathy/paresthesia grade ≥ 1. Active hepatitis B, unless patient has been on antiviral agents for at least 2 months (baseline testing not required). Active clinically serious infections (> grade 2). Major surgery or significant traumatic injury within 8 weeks of first study drug. A core pancreatic or liver biopsy does not preclude the patient from the study. Unable or unwilling to discontinue use of ketoconazole or St John's wort. Use of phenytoin, carbamazepine, phenobarbital, rifampin and rifabutin is discouraged, but not contraindicated. If patients require phenytoin, carbamazepine or phenobarbital monitoring of drug levels is suggested during the study. Pregnant or lactating women. Psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Patients With Pathologic Complete Response | Pathologic complete response was evaluated using MRI or CT and Evan's criteria for pathologic response following neoadjuvant therapy: I: <10% to no tumor cells destroyed IIa: 10-50% of tumor cells destroyed IIb: 50-90% of tumor cells destroyed III: >90% of tumor cells destroyed IIIM: sizable pools of cellular mucin IV: No viable tumor cells (complete pathologic response) IVM: Acellular pools of mucin | Up to 4 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Patients With Treatment-Related Adverse Events Grade 3 or Above | Number of unique patients who had a treatment-related (possible, probable, or definite) adverse event with grade 3 or greater using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. | Every 15 days for approximately 6 months | 
| Percentage of Patients Who Successfully Underwent Surgery After Neoadjuvant FOLFIRINOX | The percentage of patients who successfully underwent surgery after neoadjuvant FOLFIRINOX and its 95% confidence interval will be provided. | Up to 4 months | 
| Rate of R0 Resection | The percentage of patients with a final margin status of R0 after resection of their primary tumor and its 95% confidence interval will be provided. R0 resection indicates a microscopically margin-negative resection, in which no cancer cells seen microscopically at the primary tumor site. | Up to 4 months | 
| Disease Free Survival | Disease free survival is defined as the time from on study date to evidence of tumor recurrence or death from any cause. Patients who remained alive and disease free were censored at their date of last disease evaluation. | Up to 3 years | 
| Overall Survival | Overall survival was defined as the time from on study date to death due to any cause. Patients who remained alive were censored at their last known alive date. The Kaplan-Meier method was used to determine the median and 95% confidence interval. | Up to 4 years | 
| Objective Response Rate (Percentage of Patients With Complete Response or Partial Response) | Measured by RECIST v1.1 Complete response: Disappearance of all target lesions Partial response: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter The percentage of patients with objective response and its 95% confidence interval will be provided. | Up to 4 months | 
| Disease Control Rate (Percentage of Patients With Complete Response, Partial Response, or Stable Disease) | Measured by RECIST v1.1 Complete response: Disappearance of all target lesions Partial response: At least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter Stable disease: Neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum longest diameter since the treatment started The percentage of patients with objective response and its 95% confidence interval will be provided. | Up to 4 months |
