Design outcomes

Primary

Measure	Time frame
Frequency of needle tract seeding (NTS) and time to NTS recurrence in pancreatic resection neoplasms after EUS-FNA for pancreatic mass, examined separately for overall, pancreatic cancer, and pancreatic malignant neoplasm other than pancreatic cancer.	—

Secondary

Measure	Time frame
Frequency of needle tract seeding (NTS) and time to NTS recurrence in unresectable pancreatic neoplasmsafter EUS-FNA for pancreatic mass, examined separately for overall, pancreatic cancer, and pancreatic malignant neoplasm other than pancreatic cancer. Frequency of NTS detected by EGD/EUS Frequency of non-NTS lesions detected on EGD/EUS Frequency of complications in EGD/EUS examinations Image Characteristics of NTS and their associated factors Prognosis of NTS cases and their associated factors Non-NTS recurrence sites and their frequency	—
