DCE-MRI for Neoadjuvant Treatment Assessment in Patients With Borderline Resectable Pancreatic Cancer

Официальное название

DCE-MRI-Informed Neoadjuvant Chemotherapy for Borderline Resectable Pancreatic Cancer

Обзор

This clinical trial tests how well dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) with standard clinical evaluation works to assess treatment response for patients with pancreatic cancer that may be able to be removed by surgery (borderline resectable). Borderline resectable pancreatic cancer (BRPC) is a certain type of pancreatic cancer that involves the arteries or veins near the pancreas. With the right treatment before surgery, it can be removed (resected) successfully. An MRI (magnetic resonance imaging) scan creates clear images of the structures inside the body using a large magnet, radio waves, and a computer. DCE-MRI can be used to calculate the blood perfusion. Blood perfusion can show disease status. Using DCE-MRI as part of standard clinical evaluation may provide a more accurate treatment response assessment for patients with BRPC.

Подробное описание

PRIMARY OBJECTIVE:

I. To evaluate the association between the availability of DCE-MRI-derived information and R0 resection rates in patients with BRPC, compared to standard-of-care management.

SECONDARY OBJECTIVE:

I. To assess the association between DCE-MRI parameters and tumor microenvironment features measured by digital histopathology.

OUTLINE:

Within two weeks prior to therapy initiation, patients receive gadolinium based contrast intravenously (IV) and undergo DCE-MRI. Patients then undergo standard of care treatment with gemcitabine and nab paclitaxel or fluorouracil, oxaliplatin, irinotecan and leucovorin, per the treating gastroenterology oncologist. Approximately 6 weeks after therapy initiation and again within 1 week prior to surgery, patients receive gadolinium based contrast IV and undergo DCE-MRI again. Patients undergo computed tomography (CT) scan and blood sample collection throughout the study.
