Description of intervention(s) / exposure
Suspected pancreatic cancer patients listed for multidisciplinary meeting (MDM) discussion will have their abdominal CT scans assessed prior to the MDM by radiologist. The radiologist will use a structured (synoptic) reporting tool to describe in detail the anatomical nature of their disease and document this.
The synoptic report collects around 60 discrete fields of data that describe in detail the pancreatic cancer mass characteristics, blood vessel involvement and determines the extent of any disease spread (metastases). It includes an inherent diagnostic algorithm from the international consensus guidelines that helps define clearly resectable (CR), borderline resectable (BR) or locally advanced (LA) pancreatic ductal adenocarcinoma. The synoptic reporting template has been developed through close consultation with pancreatic surgeons and specialist radiologists, and it has been piloted in two hospitals in Melbourne and shown to increase the accuracy of reporting. This new RCT is to investigate whether the introduction of the structured synoptic report across Australian institutions involved in the management of pancreatic cancer provides greater accuracy of staging and diagnosis of the disease.

Radiologists will be provided individual login details to access and complete the reporting tool built on the REDCap platform. The median time needed to complete a synoptic report for a patient by a radiologist during the pilot of this synoptic report was 4 minutes, so it is assumed the time will be similar for this study. Radiologists will undergo a brief training program in the implementation of the synoptic template report. No additional skills or training is required to actually report these CT scans (which is within the usual scope of practice of the radiologists) – it simply requires the completion of the synoptic template report. The brief training will be provided by a project data manager and an experienced radiologist who had previously used the tool. The training session will be delivered online and it will take about 30 minutes to complete.
To monitor adherence to the synoptic reporting, the data manager in central project team will ensure data completeness and accuracy, quality assurance checks and audits (quality control), as well as providing ongoing training and support to participating radiologists.
This trial has a batched stepped wedge cluster-randomised study design. Hospitals will start the study in 3 batches; data collection in each batch starting up to 2 months after the start of the previous batch. In each batch, 2-3 hospitals will be randomised to the sequences of the stepped wedge design. All hospitals will continue to use their current radiology reporting processes for an initial period of at least six months. Within each batch, after each six-month period, a group of 2-3 hospitals will be randomised and commence using the new synoptic template report, until all hospitals are using the new report.
Note: The pilot study was NOT registered with the ANZCTR or any other trial registry.

Diagnosis / Prognosis
Comparator / control treatment
The comparator for this study is continued use of the baseline standard radiology reporting process at each of the participating sites (prior to randomisation to synoptic reporting).

Baseline standard radiology reporting varies, the level of detail and the style of the report being radiologist dependent. The report is dictated by radiologists reviewing scans and usually written as a narrative of varying lengths and complexity, finishing with a conclusion (this is the core work of a radiologist, i.e., reporting CT scans).

Outcomes
Primary outcome [1] 332656 0
Patient diagnosed with BR pancreatic ductal adenocarcinoma (PDAC) (yes/no). The primary objective of this trial is to determine the change in the proportion of patients diagnosed with BR PDAC before and after introduction of the synoptic report.
The definition of BR-PDAC is radiological derived from the international consensus document. No further tests or tools are required to assign a radiological allocation of BR-PDAC other than the index CT scan.

Borderline resectability of each patient will be determined at the time of each patient’s assessment.

Cumulative data will be assessed at the conclusion of the study to determine the changes in the proportion of patients diagnosed with the specific type of PDAC.
Secondary outcome [4] 414276 0
Patients planned to receive neoadjuvant chemotherapy (yes/no). To determine the change in the proportion of patients with CR PDAC planned to have neoadjuvant chemotherapy.
The multidisciplinary team (MDT) Discussion outcome document will clarify what the treatment plan is for each individual patient. If this plan documents ‘plan to receive neoadjuvant chemotherapy’ then that is a ‘yes’ to ‘plan to receive neoadjuvant therapy’. The proportion of patients who have this plan before and after the synoptic report is introduced for CR will be therefore calculated. In short, the primary source document (MDT discussion outcome) will provide the answer.

Intervention assignment
Other
Other design features
Stepped wedge cluster randomised trial with sites randomised to the time at which they will commence use of the synoptic report.
This will be done on periods of length of 6 months.
Participating sites will start the study in 3 batches (about 12 hospitals in each batch); data collection in each batch starting up to 3 months after the start of the previous batch. In each batch, hospitals will be randomised to the sequences of the stepped wedge design. Initially all hospitals in the same batch will continue to use their current standard radiology reporting (the comparator); after each six-month period, a group of hospitals (depending on the sequence) will commence using the synoptic report template (the intervention), until all hospitals are using the synoptic report.

Statistical methods / analysis
Results will be reported according to the CONSORT extension for stepped wedge trials [19]. Baseline data will be presented in a tabular form with mean and standard deviation or median with lowest and highest values, or percentages and counts as appropriate, by treatment sequence and time period.
Results will be compared between standard reporting and synoptic reporting phases. All available primary and secondary outcomes will be analysed at the patient level using mixed-effects regression models with random intercepts for each cluster in each period, assuming a discrete time decay within-cluster correlation structure and a fixed effect for the intervention. Separate fixed effects for period for each batch will be included in the models, following the recommendation in a published research paper on batched stepped wedge design by Kasza et al in 2022 (Reference: DOI: 10.1002/sim.9438). For binary outcomes, log-binomial models will initially be fitted; should these fail to converge, mixed-effects Poisson regression models will be fitted, with robust variance estimation. Results will be presented as relative risks with 95% confidence intervals, and as risk differences with 95% confidence intervals. The sensitivity of results to the assumed within-cluster correlation structure will be assessed by fitting models with random effects for each cluster only. Estimated intracluster correlations will be reported. The survival outcome will be analysed using a Cox proportional hazards model including shared frailty terms for cluster. All tests will be two-sided with statistical significance defined as p < 0.05. Analyses will be conducted in Stata v 17 or later or in R version 4.2.1 or later as appropriate.
A statistical analysis plan will be prepared and finalised prior to the dataset being released to the statistician.
