Secretin-enhanced Magnetic Resonance Imaging (S-MRI) for Pancreatic Cancer Detection

Pancreatic Cancer Clinical Trial

Official title: MRI With Secretin Enhancement to Increase Conspicuity of Pancreatic Cancer

Status Withdrawn

Clinical Trial Summary

The aim of the study is to evaluate the utility of secretin-enhanced MRI (S-MRI) in detecting and measuring pancreatic lesions in patients with known adenocarcinoma or Intraductal papillary mucinous neoplasm (IPMN) lesions. The hypothesis is that S-MRI is superior to MRI without secretin enhancement (N-MRI) in increasing tumor conspicuity, allowing for improved identification and more accurate measurement of lesions or precursor lesions in the pancreas.

Clinical Trial Description

Pancreatic cancer remains the fourth leading cause of cancer-related death in the United States and is marked by advanced stage at diagnosis and a high mortality rate. Intraductal papillary mucinous neoplasm (IPMN) is a cystic lesion that can be potentially cancerous, leading to pancreatic adenocarcinoma. Currently, there is no existing imaging modality that is both sensitive and cost-effective enough in accurately measuring or detecting adenocarcinoma and IPMN. Improving the methods used in identification and localization of this disease is critical.

Secretin, a hormone produced by duodenal mucosal cells increases blood-flow to the pancreas. The investigators' hypothesis is that as secretin increases blood flow to the pancreas, there will be increased conspicuity in areas of dysplasia/cancer where there is minimal blood-flow, enhancing tumor detection. The investigators are conducting a prospective, randomized-control pilot study of thirty subjects with IPMN or pancreatic cancer who are undergoing surgical resection at Columbia University's Pancreas Center. Fifteen subjects will be randomly selected to undergo S-MRI prior to surgery and fifteen subjects will be selected as controls, undergoing MRI without secretin-enhancement and matched for age, sex, race and tumor-type. The investigators will first evaluate if secretin allows for increased tumor conspicuity, enhanced visualization of the lesion, by comparing the calculated tumor conspicuity of S-MRI to N-MRI groups.

The investigators will then assess if S-MRI imaging allows for increased accuracy in lesion measurements by looking at the concordance in measurements between S-MRI and tumor specimens post-resection as compared to the concordance in measurements between N-MRI and tumor specimens post-resection. ;
