Conditions
Summary
Prospective multicenter study in which all patients with borderline or locally advanced pancreatic adenocarcioma undergoing neoadjuvant chemotherapy and surgical exploration with curative intent will be included for one year. Preoperative images by traditional CT and 3D-MSP technology will be evaluated, comparing the accuracy variables (sensitivity, specificity, predictive values, area under the curve, concordance index) of both techniques with the gold standard (results of surgery and histopathological analysis).
Eligibility
Inclusion Criteria1
- \- Patients with a diagnosis of borderline or locally advanced PAC of the head of the pancreas, as defined by the National Comprehensive Cancer Network (NCCN), who have received neoadjuvant treatment and who undergo surgical exploration with resective intent.
Exclusion Criteria5
- Patients younger than 18 years of age.
- Patients under 18 years of age.
- Disease progression during neoadjuvant treatment.
- No preoperative CT scan.
- Refusal to participate in the study.

Interventions
The processing of the CT images obtained in each center for the creation of the 3D model will be performed centrally by the team of radiologists and computer scientists of the company Cella Medical Solutions. This team will be blinded to the reports of the CT scans.For each patient 4 NCCN check-lists will be filled in without knowing the result of the surgery or the AP study: 2 based on the conventional CT and two based on the 3D-MSP study.
A multiphase CT (venous phase and pancreatographic phase) with 1mm thick slices and series of images in coronal, axial and sagittal reconstructions will be performed. This CT model will be performed at disease diagnosis and after completion of neoadjuvant chemotherapy treatment. Both CT scans will be independently reported by a radiologist from the hospital of origin. The preoperative CT scan will also be evaluated a posteriori by a radiologist from the sponsoring center with expertise in PAC. Both reports (the one from the radiologist of the center and the one from the radiologist of the sponsoring center) will be used to fill out the imaging study variables sheet based on the latest version of the NCCN 2022 guidelines. The radiologists will not know the outcome of the surgery or the anatomic pathology study at the time of the completion of the report.
