Brief Summary:
This is a research study in which bio-specimens (whole blood, plasma and serum from peripheral circulation and portal vein) will be collected from patients with pancreatic adenocarcinoma for translational research. These samples will be used for (but not limited to) identification and characterisation of blood-borne biomarkers at the genomic and protein expression level. Examples of such biomarkers are circulating tumour cells (CTCs), CTC clusters and circulating DNA (which can be tumour derived, or from unaffected/normal cells). CTC-enriched blood samples may also be used to generate CTC-derived tumour explant (CDX) models in immunocompromised mice in order to produce suitable disease models in which to test novel therapies and identify new molecular targets. In addition, permission will be sought from study participants for the research team to access clinical information from medical notes to aid in determining the clinical relevance of biomarkers identified during the course of this study. Validated biomarkers are anticipated to be used in designing future biomarker-directed clinical trials in these disease groups.

Arm Intervention/treatment
Single Arm
Observational study of CTC microemboli in portal vein blood samples.
Diagnostic Test: Portal vein sampling
During Endoscopic UltraSound guided-Fine Needle Aspitation (EUS-FNA) a curvilinear echoendoscope is advanced to the distal stomach or duodenal bulb to provide a window of access to a branch of the PV. After verifying venous flow by Doppler signal, a 19-gauge EUS-FNA needle is advanced transhepatically into the portal vein branch. With the needle in the portal vein, the stylet is removed and negative-pressure suction is applied to aspirate blood. A transhepatic approach for portal vein branch access is an absolute requirement of this technique in order to minimize the risk of bleeding. The puncture site is monitored under EUS for complications.

Primary Outcome Measures :
  1. Blood-borne biomarker analysis for PDAC [ Time Frame: 12 months ]
    To prospectively collect paired peripheral and portal vein serum, plasma and whole blood samples for translational research at various time points. To investigate the presence of Circulating Tumour Cells and Circulating Tumour Microemboli and their biological significance. To investigate potential prognostic and predictive blood-borne genetic, protein and/or messenger ribonucleic acid biomarkers using the collected specimens.

Secondary Outcome Measures :
  1. Correlation of identified biomarkers with progression free and overall survival [ Time Frame: 24 months ]
    To prospectively collect progression free and overall survival data so that correlation between biomarker parameters and clinical parameters can be examined.

  2. Investigation germline genetic biomarkers [ Time Frame: 12-24 months ]
    Investigation of potential predictive blood germline genetic biomarkers using the collected specimens.

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: No
Plan Description: Identifiable personal data (IPD) will be reviewed by the investigators listed on the trial delegation log at the stage of reviewing the medical records during the hepatopancreatobiliary (HPB) MultiDisciplinary Team (MDT) meeting at Manchester University Foundation Trust where the recruitment process will start. The medical notes will also be reviewed to correlate biomarker research with clinical outcomes.
