Objectives

Narrative objectives1

Pancreatic cancer may be accompanied by occult peritoneal dissemination that cannot be detected by imaging, regardless of resectability status or the presence of other distant metastases. This risk is considered to be higher in patients with elevated tumor markers.

This study targets patients with pancreatic cancer who have no apparent peritoneal dissemination on imaging. In these patients, peritoneal lavage cytology using EUS-FNA will be performed to determine the positivity rate of occult peritoneal dissemination, with the aim of contributing to more accurate staging and the selection of optimal treatment strategies for individual patients.
