Inclusion criteria
Inclusion criteria: pancreatic juice cytology for patients with highly suspected small pancreatic cancer without visible mass by endoscopic ultrasound from May 2015 to April 2023.
Exclusion criteria
Exclusion criteria: First, PJC for the diagnosis of suspected intraductal papillary mucinous neoplasm (IPMN) with high-grade dysplasia/carcinoma derive from IPMN was excluded because of the different nature of tumor. PJC for suspected PDAC with visible mass by EUS due to the failure diagnosis of EUS-FNAB was also excluded. Patients with PJC positive results who underwent imaging follow-up less than one year without surgical resection and patients with PJC negative results who underwent imaging follow-up less than five years without surgical resection were excluded as undiagnosed cases, considering the progress nature/period of HG-PanIN and invasive PDAC.
