COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Diagnosis / Prognosis - Rapid on-site evaluation (ROSE)
Diagnosis / Prognosis - Histologic evaluation

Active Comparator: EUS-FNB with ROSE - Intervention: Rapid on-site evaluation (ROSE) In the EUS-FNB with ROSE arm, the material obtained with the first pass will be processed for ROSE using the touch imprint technique. The biopsy specimen is carefully pressed onto the slide, allowing the superficial cells to adhere, and then gently lifted with forceps thereby creating a touch imprint of the specimen on the slide. In case of inadequate sample, a second pass will be done and the touch imprint technique will be repeated up to a maximum of 3 passes. In case of adequate ROSE at the first or the second pass, the additional passes will be performed as EUS-FNB and the material obtained placed directly into formalin or other fixative for subsequent histopathological evaluation.

Active Comparator: EUS-FNB without ROSE - Intervention: histologic evaluation In the FNB alone arm, 3 needle passes will be performed and the samples obtained will be placed directly in a vial containing formalin (or other fixative according to the local individual protocol). Macroscopic on-site evaluation (MOSE) of acquired sample will be then performed by the endoscopist.

Diagnosis / Prognosis: Rapid on-site evaluation (ROSE)
On-site evaluation of the acquired samples will be performed by pathologist

Diagnosis / Prognosis: Histologic evaluation
Samples collected in the EUS-FNB without ROSE will be processed as histologic samples

Samples blood contamination - Blood contamination will be evaluated by attributing a score from zero to 3 (3 represents the better outcome), according to the following score system:
0=Only blood. 1=Much blood contamination, surface area > 50 % of the slide. 2=Medium blood contamination, surface area 25-50 % of the slide. 3=Little blood contamination, surface area < 25 % of slide.

Brief summary
Rationale: Rapid on-Site Evaluation (ROSE) of cytologic specimens acquired with EUS-guided
fine needle aspiration (EUS-FNA) represents the most accurate available technique to reach a
definitive diagnosis in patients with pancreatic solid masses. Cytologic interpretation,
however, requires a high degree of expertise rarely found outside high volume centers and
ROSE is not available in many countries. This has created a barrier to the widespread
dissemination of EUS in the community and throughout the world, because the lack of cytologic
expertise has resulted in a low diagnostic accuracy and, therefore, in a limited perceived
utility of EUS. A device that is able to: (i) acquire histologic core biopsy samples usually
easier to be interpreted; (ii) be used by most of the endosonographers and not only by the
experts; (iii) have a performance at least not inferior to ROSE, will represent a major
breakthrough in the field of EUS tissue acquisition. The availability of such needles will
determine a shift from cytology to histology that will overcome some of the limitations of
cytology and ROSE, thus strongly contributing to the diffusion of EUS throughout the world
and in the community.

Objectives: To compare the performance and the diagnostic accuracy of EUS-guided fine needle
biopsy (EUS-FNB) coupled with ROSE with that of EUS-FNB alone using an FNB needle.

Study design: International randomized multicenter trial. Study population: Patients =18
years old, referred for EUS-guided tissue sampling of a solid pancreatic mass.

Intervention: EUS-guided tissue acquisition by means of either EUS-FNB with ROSE or EUS-FNB
alone, using one of the following FNB needles: Procore 20-gauge, SharkCore 22-gauge or
Acquire 22-gauge.

Main study parameters/endpoints: The main endpoint is the diagnostic accuracy, measured
against the gold standard diagnosis that will be surgical resection specimen or in
non-operated patients the results of other diagnostic work-up (other tissue sampling
techniques and imaging studies) or the clinical course of the disease. Secondary endpoints
include: i) safety; ii) presence of tissue core; iii) feasibility to perform additional
immunohistochemical/molecular biology analyses; iv) time of the sampling procedure.
