The experimental 18F-FLT-PET/CT is required to be completed before initiation of chemotherapy. Labs and correlative radiology, as directed per clinical care, are required within 30 days prior to 18F-FLT-PET/CT; and 18F-FDG-PET/CT is required within 30 days before the 18F-FLT-PET/CT. Follow-up will comprise 24 months of standard practice treatment and follow up. Visit 1: Patients will have at least one visit with investigator (or investigator designee) prior to the study to review clinical history and prior treatment of pancreatic adenocarcinoma, and to explain the study. Correlative radiology studies including CT, MRI and 18F FDG-PET/CT as per institutional routine clinical care, and any clinically-directed laboratory tests performed as part of staging must be performed within 30 days of the 18F FLT-PET/CT Visit 2 (Optional): The 18F-FDG-PET/CT may be done as a research scan, if the patient is unable to obtain a clinically-directed 18F-FDG-PET/CT as part of their clinical care or within 30 days of 18F FLT-PET/CT. The research 18F-FDG-PET/CT, in this instance, will be identical in procedure to the institution's clinical 18F-FDG-PET/CT. The blood glucose level will be < 200 mg/dl, before 18F-FDG injection, which is institutional standard clinical protocol. The following additional patient data will be obtained: histological diagnosis of primary and/or metastatic disease, date of diagnosis of primary and metastatic disease, gender, height, weight (for BMI), ECOG score and confirmation of absence of prior treatment. Visit 3: Day of 18F-FLT-PET/CT: The patient will have an intravenous line placed in the hand or arm, 18F-FLT-PET/CT will be given by 1-2 minute IV push, and the dose administered will be approximately 5 mCi (+/- 20% dose). After approximately 60 +/- 10 minutes of uptake time, the patient will be positioned supine in the PET/CT scanner for standard whole body PET/CT scan from the skull base to mid-thigh. This scan will take approximately 20-30 min. The window from FLT PET/CT baseline study to initiation of chemotherapy should be no more than 30 days. Visit 4: Day of Interim 18F-FLT-PET/CT: The interim 18F FLT-PET/CT will be performed after the 2nd cycle of chemotherapy regimen, but before the commencement of 3rd cycle. The second 18F-FLT-PET/CT study must be performed on the same scanner as the first 18F FLT-PET/CT and the imaging protocol described in Visit 3 should be closely followed. Study duration: Clinical Follow Up: Standard of care clinical follow-up data will be collected up to 2 years following the end of chemotherapy. .
