The purpose of this study is
- to determine whether the perfusion parameters in the normal pancreas and the pancreas cancer (adenocarcinoma or neuroendocrine tumor) are different on perfusion CT
- to determine whether initial perfusion parameters as well as perfusion parameter change in pancreas adenocarcinoma before and after chemotherapy are different between chemotherapy response group (CR, PR according to RECIST 1.1) and non response group (SD, PD according to RECIST 1.1).
|Condition or disease||Intervention/treatment|
|Adenocarcinoma, Pancreas Neuroendocrine Carcinoma of Pancreas||Drug: iopromide Procedure: CT|
- Performance of preoperative perfusion CT for preoperative staging is assessed by comparing with operative finding and histologic disease staging
- Estimation of initial or change of pancreas cancer perfusion parameters and whether those can provide cut-off value for predicting response of chemotherapy in patients with pancreas adenocarcinoma
|Study Type :||Observational|
|Actual Enrollment :||48 participants|

Resectable pancreas cancer
patients with resectable pancreas adenocarcinoma or neuroendocrine tumor underwent perfusion CT after intravenous iopromide administration
Other Name: Ultravist® (370mgI/mL)
Locally advanced Pancreas cancer
Patients with locally advanced pancreas cancer underwent perfusion CT after intravenous iopromide administration before and after chemotherapy.
Other Name: Ultravist® (370mgI/mL)
- Evaluation of the correlation between the initial perfusion parameters of the tumor and response of the chemotherapy [ Time Frame: after 6 cycles of the planned chemotherapy ]Initial perfusion parameters (blood volume, blood flow and permeability) are compared between CTx-responder and non-responders after 6 cycle of the scheduled chemotherapy, using RECIST 1.1 criteria.
- Correlation between change of perfusion parameters and the chemotherapy response [ Time Frame: after 6 cycles of the chemotherapy ]Perfusion parameters (blood volume, blood flow, and permeability) change between initial perfusion CT and second perfusion CT (which is taken after 2 cycle of the CTx) are compared between CTx-responder and non-responder after finishing 6 cycles of CTx according to RECIST 1.1 criteria.
- Perfusion parameters among different pancreas tumors [ Time Frame: within 2 months after finishing enrollment ]Perfusion parameters (blood volume, blood flow and permeability) are compared among the different types of the pancreas tumors to investigate perfusion parameters can help characterization of the tumors.
- comparison of perfusion parameters among the pancreas tumors and parenchyma [ Time Frame: within three weeks before pancreas tumor surgery ]blood volume, blood flow and permeability are compared between the tumor and the pancreas parenchyma.
