Background
A standardized method for predicting unresectability in pancreatic cancer has not been defined. We propose a system using CT and endoscopic ultrasound (EUS) to assess patients for unresectable pancreatic cancers.
Methods
Radiologic and surgical data from 101 patients who underwent exploration/resection for pancreatic cancer were reviewed. Chi-squares were used to identify five factors significantly correlated with unresectability, which were incorporated into a scoring system (one point for each factor).
Results
The resectability rates were 84, 56, and 10% for patients with scores of 0, 1, and 2, respectively. All four patients with three risk factors for unresectability had unresectable tumors. The most accurate results were achieved in patients evaluated with both CT and EUS.
Discussion
This scoring system stratifies pancreatic cancer patients into three groups: (1) patients with a score of zero (likely to undergo successful resection), (2) patients with a score of one (likely to benefit from laparoscopic staging prior to attempting resection), and (3) patients with a score of two or higher (low probability of successful resection, who may be better served by neoadjuvant therapy).
