SECONDARY outcome

Timeframe: up to 2 years

Population: 3 patients excluded from analysis population in 19G Flex Arm due to histology diagnosis of neuroendocrine tumor (1), EUS diagnosis of neuroendocrine tumor (1), and solid cystic papillary neoplasm (1). 2 patients excluded from analysis population in 22G Arm due to missing EUS diagnosis (1) and EUS diagnosis of SPEN (1). 4 patients excluded from analysis population in 19G Arm due to missing EUS diagnosis (1) and EUS diagnosis of neuroendocrine tumor (3).

In order to assess the accuracy of EUS-FNA-based standard assays (cytology and CEA) as a diagnostic measure of disease state, the Disease State per EUS-FNA measure was compared to a reference diagnosis. The reference diagnostic standard was diagnosis from a surgical specimen histology, the true gold standard for cases that evolved to surgical resection within the follow-up of the study. For cases that did not progress to surgery within the follow-up period, the reference diagnostic standard was a composite diagnosis by a consensus board. The consensus board consisted of 3 experts who were blinded to the type of needle used. The consensus board diagnoses of disease state were based on baseline medical history, EUS and cross sectional imaging of the cyst, and aspirate characteristics (i.e. aspirate color and viscosity). If the EUS-FNA diagnosis matches with the histopathology or consensus board diagnosis, then the participant will be counted as having accurate diagnosis.

In the case of inability to access the pancreatic cystic lesion or to attain complete cyst aspiration, salvage aspiration procedure should be performed. Patients randomized to 19G Flex should undergo a salvage procedure with 22G or 19G needle (needle choice at discretion of physician); patients randomized to 22G or 19G should undergo salvage procedure with 19G Flex needle.
