Intervention/exposure

Description of intervention(s) / exposure
primovist MRI
patients will undergo primovist MRI as part of their work up for presentation with locally resectable pancreatic cancer

An MRI is a scan, which does not expose the patient to any ionizing radiation. A contrast agent is injected through a cannula, usually in the arm. Patients are then required to lay flat on their back for the duration of the scan, which is usually about 35 minutes. The contrast injected in this situation would be Primovist.
Primovist is a liver specific contrast, which helps characterize liver lesions in MRI more accurately. It has been available since 2005 and is used with increasing confidence in many liver centres. It is TGA approved but not yet available on Medicare.

the primovist MRI will be in addition to the multiphase CT as this is the usual test to assess the liver but also the pancreas cancer and its relationship to vessels and the chest for disease.
most patients will undergo one MRI but may undergo a second if they are given neoadjuvant chemotherapy as they will then need restaging for possible surgery.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The participant will be enrolled into the study after the informed consent process has been completed and the participant has met all the inclusion criteria and none of the exclusion criteria. The patient details will be forwarded to the central office, which will allocate randomisation, record and track the study progress.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Given the nature of the study it will not be possible to blind the patients or the physicians involved the study. We will use blocked randomization to ensure a 2 to 1 randomization. We will use the randomization tool RANDI2, available at http://dschrimpf.github.io/randi3/.

At the beginning of the study we will produce a set of 24 of numbered and sealed envelopes with the sequence of group allocation, according to the randomization. The envelopes will be kept at the project headquarters and for each new patient entering the study an envelope will be opened to define his/hers trial arm.

Statistical methods / analysis


Pilot study of 24 patients to test the planned methods and procedures, including the feasibility of recruiting from this patient group and also to support an application for further funding to extend the study. We aim to establish preliminary estimates of 3 phase CT and Primovist MRI detection rates of liver metastases and 12-month recurrence risk.

The largest number of patients we can expect to recruit in this time, over the listed sites is about 24. It is our intention to complete recruitment to the pilot close to the time we expect to commence the larger study so that we do not lose the familiarity and momentum developed amongst the local clinicians before we start recruitment to the larger study.

Also it may give us some realistic appreciation of the differences between 3 phase CT and Primovist MRI detection rates, which would complement our existing information and assumptions for the sample size calculations for the larger study.



The sample is underpowered to test differences between the two groups. However, this is a pilot study. Twenty-four patients provide 60% power to detect a reduction from 70% to 25%, for a significance level of 0.05.



Patient’s characteristics will be summarised by study arm to assess the comparability of the groups. The main analysis will be the estimation of the risk of recurrence at 12 months in the two arms. Exact 95% confidence intervals will be provided for the risk estimates. Additionally, we will use Fisher’s exact test to compare the two risks.

Summary
Brief summary
This study aims to determine whether the use of Primovist magnetic resonance imaging (MRI) in assessment of pancreatic cancer liver metastases would result in changes in clinical decision-making for these patients and more appropriate treatment decisions. Who is it for? You may be eligible to join this study if you are aged 18 to 85 years old, and have a confirmed diagnosis of locally operable pancreatic adenocarcinoma with no liver metastases on CT staging. Study details Participants in this study will be randomly (by chance) allocated to one of two groups. Participants in one group undergo primovist MRI in addition to standard multiphase CT of the abdomen and CT of the chest as part of their preoperative assessment for pancreatic resection. This involves an MRI, which is a scan, which does not expose the patient to any ionizing radiation. A contrast agent is injected through a cannula, usually in the arm. Patients are then required to lay flat on their back for the duration of the scan, which is usually about 35 minutes. The contrast injected in this situation would be Primovist.
Primovist is a liver specific contrast, which helps characterize liver lesions in MRI more accurately. It has been available since 2005 and is used with increasing confidence in many liver centres. It is TGA approved but not yet available on Medicare, and usually takes about 30 minutes. Participants in the other group will undergo standard preoperative assessment which consists of a multiphase CT of abdomen and contrast CT of chest . A CT scan is the current standard scan used to assess pancreas cancer. A cannula for the intravenous contrast is required. There can be discomfort related to its insertion and possible bruising at the site. Although there is exposure to radiation with the CT scan, which is the standard assessment, performed in pancreatic cancer liver assessments there is no additional ionizing radiation from the MRI. All participants will be re-assessed with three monthly CT scans of chest, abdomen and pelvis and tumour markers. Just using CT scans will allow assessment of recurrence, using current standards.
The information from follow up scans will allow us to evaluate recurrence rate at 12 months following surgery and the existence of liver metastases. It is hoped that Primovist MRI will be found to be superior to the standard CT tests in the detection of liver metastases in pancreatic cancer, and that this leads to more relevant and appropriate treatment options for patients with pancreatic adenocarcinoma.
