Combination Chemotherapy With or Without Hypofractionated Radiation Therapy Before Surgery in Treating Patients With Pancreatic Cancer
This randomized phase II trial studies how well combination chemotherapy (mFOLFIRINOX) with or without hypofractionated radiation therapy before surgery works in patients with pancreatic cancer that can be removed by surgery. Drugs used in combination chemotherapy, such as oxaliplatin, leucovorin calcium, fluorouracil, and irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. It is not yet known if combination chemotherapy is more effective with or without hypofractionated radiation therapy before surgery in treating patients with pancreatic cancer.
PRIMARY OBJECTIVES: I. To evaluate and estimate 18 months overall survival (OS) rate of patients with borderline resectable pancreatic ductal adenocarcinoma (PDAC) receiving neoadjuvant therapy. SECONDARY OBJECTIVES: I. To evaluate and estimate the R0 resection rates in patients receiving each of the two multimodality treatment regimens. II. To evaluate and estimate the event-free survival in patients receiving each of the two multimodality treatment regimens. III. To evaluate and estimate the pathologic compete response (pCR) rates in patients receiving each of the two multimodality treatment regimens. IV. To assess the adverse events (AE) profile and safety of each treatment arm. TERTIARY OBJECTIVES: I. To test the effect of the rs2853564 vitamin D receptor (VDR) variant on OS rate and discover novel candidate genes associated with OS and severe toxicity of chemotherapy by using genome-wide genotyping approaches. II. To evaluate risk classification previously developed by Koay et al using normalized area under the enhancement curve (NAUC). III. To access prognostic value of NAUC ratio defined as post-neoadjuvant NAUC divided by pre-neoadjuvant therapy NAUC. IV. To evaluate risk classification previously developed by Koay et al using delta measure. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM A: Patients receive oxaliplatin intravenously (IV) over 2 hours, irinotecan IV over 90 minutes, and leucovorin calcium IV over 2 hours on day 1. Patients also receive fluorouracil IV continuously over 46-48 hours on days 1-2. Treatment repeats every 14 days for 8 courses in the absence of disease progression or unacceptable toxicity. ARM B: Patients receive oxaliplatin intravenously (IV) over 2 hours, irinotecan IV over 90 minutes, and leucovorin calcium IV over 2 hours on day 1. Patients also receive fluorouracil IV continuously over 46-48 hours on days 1-2. Treatment repeats every 14 days for 7 courses in the absence of disease progression or unacceptable toxicity. Patients receive either stereotactic body radiation therapy (SBRT) or hypofractionated image guided radiation therapy (HIGRT) on days 1-5 of course 8. SURGERY Within 4 to 8 weeks after the last dose of chemotherapy (arm A) or of radiation (arm B), patients considered surgical candidates for resection (after central review) will undergo surgery at the registering institution. ADJUVANT CHEMOTHERAPY Within 4-12 weeks from the date of surgery, patients will receive oxaliplatin IV over 2 hours and leucovorin IV over 2 hours on day 1. Patients also receive fluorouracil IV continuously over 46-48 hours on days 1-2. Treatment repeats every 14 days for 4 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 16 weeks for 2 years, then every 6 months for 5 years.

| Primary Outcome Measures | Measure Description | Time Frame |
|---|---|---|
| Overall Survival (OS) Rate | Defined as the percentage of patients who are alive at 18 months after randomization divided by the total number of evaluable patients in each arm. An evaluable patient is defined as any patient who signed informed consent, deemed eligible by central review and received any protocol-defined treatment. 95% confidence interval will be estimated based on standard method. Chi-squared test (or Fisher's exact test if the data in contingency table is sparse) will be used to compare 18 month OS rates among treatment arms. OS within each arm will be summarized by Kaplan-Meier method. Median, 1-year and 2-year rates will be estimated based on Kaplan-Meier curves. | 18 months |
| Secondary Outcome Measures | Measure Description | Time Frame |
|---|---|---|
| Residual Tumor (R)0 Resection Rate | Defined as the percentage of patients in whom an achieved R0 resection was achieved during surgery. | 24 months |
| Event-free Survival | Defined as time from randomization to the first documentation of event where events considered are 1) disease progression, per RECIST, prior to surgery, 2) surgery with R2 resection, 3) recurrent disease following surgery, or 4) death due to any cause. Will be estimated using the method of Kaplan-Meier in each arm and compared between treatment groups using the log-rank test. The correlation between pathologic complete response (pCR) status and event-free survival time will be assessed by Cox model with landmark approach. | 4 years and 7 months |
| Pathologic Complete Rate (pCR) Rate | Defined as the percentage of patients in whom a pCR was confirmed by histopathologic review of the surgical specimen. Chi-square test (or Fisher's exact test if the data in contingency table is sparse) will be used to compare pCR resection rate between two treatment arms. Sensitivity analysis will be conducted among patients in cohort 1) and cohort 2). The association between pCR rate and OS/progression free survival (PFS) will be assessed by log-rank test and Cox model. | 24 months |
| Incidence of Adverse Events Assessed Per Common Terminology Criteria for Adverse Events (CTCAE) Version 4 and the Patient-Reported Outcomes Version of the CTCAE | Overall adverse event rates will be compared between treatment groups using Chi-square test (or Fisher's exact test if the data in contingency table is sparse). | 1 year |
