Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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

Description of intervention(s) / exposure
Evaluation of fine needle biopsy (FNB) for endoscopic ultrasound (EUS) guided tissue acquisition of pancreatic masses to negate the need for rapid on-site evaluation: a multi-centre randomized control trial
Eligible patients will be invited to participate in the trial and provided with the Patient Information Sheet and encouraged to ask questions. Once the patient has agreed to go ahead with the study they will be asked sign the consent form. Consenting patients will be randomized to either group A or group B. The randomization sequence will be determined using a central computerized randomizing program. In both groups, the procedure will be performed at the Department of Gastroenterology, Royal Adelaide Hospital, under deep sedation (Propofol, as determined by patient weight), administered by qualified anaesthetists. After the lesion is evaluated by EUS, the endoscopist will perform the tissue sampling using the most appropriate pathway deemed at the time.
Group A will undergo EUS fine needle aspiration (FNA) with the 22G EchoTip needle. Each pass will undergo rapid on-site evaluation (ROSE) by a trained cytopathologist or cytotechnician (ROSE slides prepared in the endoscopy suite with Papanicolaou stain and the remaining sample to be placed into Hanks solution in order to develop a paraffin embedded cell block). The degree of suction will be determined by the endoscopist and the degree of “bloodiness” of the specimen. The endoscopist will perform passes until the cytopathologist or cytotechnician satisfies the quality of specimen that allow determination of the diagnosis, to a maximum of 7 passes.
Group B will undergo EUS FNB with the 22G ProCore needle without the presence of ROSE. A total of 4 passes will be done per lesion using suction via a 10ml syringe (with the fanning technique done when possible). All aspirated material will be placed in formalin to undergo direct histological processing (filtered through a microcassette, immersed in Ponceau S tinted neutral buffered formalin and processed as standard histological blocks).
All patients will be observed in recovery for a minimum 2 hours following the procedure for any complications.
Trained cytologists and pathologists will assess the final processed samples from each group in order to determine the diagnosis. The diagnostic reports will be stratified into the following categories:
1. Positive for malignancy
2. Suspicious for malignancy
3. Atypia
4. Negative for malignancy

Outcomes
Primary outcome [1] 302723 0
To compare the differences in the diagnostic yield between the groups.

This will be determined via 2 methods:
1. Definite histological diagnoses from surgically resected specimens.
2.In the absence of surgical resection, a minimum 24 weeks follow-up will be done. Lesions that resolve spontaneously or do not progress (as seen on imaging) will be considered benign. If lesions progress (enlarge or metastasize) then those lesions will be considered malignant.
Timepoint [1] 302723 0
2 days post procedure diagnoses are made. Differences between groups to be compared once a sufficient patients have been diagnosed, approximately 1 year within commencement of study.
In the absence of surgical resection, a minimum 24 weeks follow-up will be done, and a maximum 48 weeks.
Secondary outcome [1] 336827 0
To compare the differences between tissue characteristics between the needles.

Assessed by trained cytologists and pathologists, the final processed samples from each group in order to determine the diagnosis. The diagnostic reports will be stratified into the following categories:
1. Positive for malignancy
2. Suspicious for malignancy
3. Atypia
4. Negative for malignancy
Timepoint [1] 336827 0
2 days post procedure diagnoses are made. Differences between groups to be compared once a sufficient patients have been diagnosed, approximately 1 year within commencement of study.
Secondary outcome [2] 336828 0
To compare the differences between complication rates in the groups.

Assessed via medical records, monitoring primarily for bleeding, perforation and pancreatitis
Timepoint [2] 336828 0
This outcome is assessed 7 days post procedure via medical records. In the absence of surgical resection, a minimum 24 weeks follow-up will be done, and a maximum 48 weeks.
Secondary outcome [3] 336829 0
To compare the differences between groups for the need to repeat procedure.

Assessed via medical records and with communication with the cytologists and pathologists.
Timepoint [3] 336829 0
Within 2 days post procedure the need for repeat procedure is usually determined. In the absence of surgical resection, a minimum 24 weeks follow-up will be done, and a maximum 48 weeks.
Secondary outcome [4] 336860 0
To compare the procedural time required for both procedures. This outcome is assessed by monitoring and recording time taken during the procedure.
Timepoint [4] 336860 0
Procedure time determined during the procedure. Differences between groups to be compared once sufficient patients have been diagnosed, approximately 1 year within commencement of study.
Secondary outcome [5] 336861 0
To compare time required for specimen processing for both procedures. This outcome is assessed by monitoring and recording time taken during specimen processing.
Timepoint [5] 336861 0
Specimen processing time is determined within 2 days of procedure. Differences between groups to be compared once sufficient patients have been diagnosed, approximately 1 year within commencement of study.
Secondary outcome [6] 336862 0
To compare the time required for diagnosis from both procedures. This outcome is assessed by monitoring and recording time taken to receive diagnosis of patient’s results.
Timepoint [6] 336862 0
Diagnosis time is determined within 2 days of procedure. Differences between groups to be compared once sufficient patients have been diagnosed, approximately 1 year within commencement of study. In the absence of surgical resection, a minimum 24 weeks follow-up will be done.
Lesions that resolve spontaneously or do not progress (as seen on imaging) will be considered benign. If lesions progress (enlarge or metastasize) then those lesions will be considered malignant.
