Brief summary
Pancreatic ductal adenocarcinoma (PDAC) is diagnosed at an advanced, incurable stage in more than 80% of cases in Switzerland. Certain warning signs - new-onset diabetes, unexplained weight loss, or a family history of pancreatic cancer - may indicate elevated risk, but are not systematically assessed in primary care. PANCATCH-Pilot tests whether a structured case-finding pathway in Swiss general practices is feasible. Adults aged 60 years or older with one or more of these risk factors are invited to undergo an MRI/MRCP examination of the pancreas and a blood draw for a blinded biomarker test (PancreaSure, Immunovia Inc.). Findings are reviewed by a multidisciplinary tumour board. The goal is not treatment, but to assess whether such a pathway works in the Swiss primary care context - as preparation for a larger national study. The study enrolls 50 trigger-positive participants over 24 months through two parallel recruitment pathways: GP referral and self-presentation via a study website. Feasibility is assessed using six combined endpoints covering recruitment, process quality, safety, and equity.
Interventions
Single-visit structured pathway comprising: (1) standardised clinical risk assessment; (2) MRI/MRCP with macrocyclic gadolinium contrast agent (Dotarem) per PRECEDE consensus protocol; (3) blood draw for blinded PancreaSure serum biomarker assay (Immunovia Inc.) and study biobank; (4) multidisciplinary tumour board review. No therapeutic intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Composite Feasibility Score | 24 months | Feasibility assessed by dual-criterion approach (Roychoudhury et al. 2018) across 6 combined endpoints: (1) GP recruitment rate ≥60%; (2) trigger documentation rate ≥70%; (3) T0-T4 time window median ≤21 days; (4) data completeness ≥85%; (5) harm indicator (invasive follow-up procedures) ≤25%; (6) equity index (Spread Quotient ≤4 and Representation Index 0.7-1.3). Study success criterion: ≥5 of 6 endpoints meet both target value and acceptance threshold. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| PancreaSure Biomarker Performance | Through study completion, an average of 3 years | Blinded exploratory characterisation of PancreaSure serum biomarker assay performance in a Swiss primary care population. Hypothesis-generating only; no inferential statistics planned. |
| Multidisciplinary Tumour Board Process Characterisation | 24 months | Descriptive characterisation of the MDT tumour board process including case volume, time from MRI to board discussion, and board composition. |
| GP Experience with Study Pathway | 24 months | Semi-structured questionnaire assessing GP experience with the case-finding pathway, including perceived burden, clarity of trigger criteria, and willingness to participate in a national main trial. |
| Participant Experience with Study Pathway | 12 months | Structured assessment of participant-reported experience with the study pathway including perceived burden, satisfaction with communication, and willingness to recommend participation. |
