A Prospective Translational Tissue Collection Study in Early and Advanced Pancreatic Ductal Adenocarcinoma and Pancreatic Neuroendocrine Tumours to Enable Further Disease Characterisation and the Development of Potential Predictive and Prognostic Biomarkers

Study Overview
=================
Brief Summary
-----------------
There are several types of early pre-cancerous lesions found in the pancreas which have the potential to develop into pancreatic cancer. Although different patients' pancreatic cancers or pre-cancerous pancreatic lesions have many similarities we believe that subtle differences can affect how they behave and therefore influence individual patient outcomes. Many factors may account for the differences seen in pancreatic lesion behaviour, for example molecular and genetic differences (the DNA and RNA present which control how a cell grows and divides), differences in how the immune system responds to the lesion, differences in the environment immediately around the lesion in the pancreas, known as the tumour microenvironment and differences in the micro-organisms which colonize a particular patient, known as their microbiota . This project studies the molecular makeup of pancreatic lesions and their microenvironment at various stages (from pre-cancerous lesions all the way through to more advanced disease) to see if we can use this information to divide patients into different groups whose lesions may behave in similar ways. We will be trying to find out if there are molecular reasons why some patients respond to particular treatments when others do not, why some patients experience more toxicity with particular treatments and why some patients' disease behaves particularly aggressively when other patients' disease does not. We will also be investigating the particular micro-organisms colonizing individual patients to see if these impact a patient's outcome. Understanding what makes one person's pancreatic lesion behave differently to another's could lead to better treatment, where a personalized therapeutic strategy could be applied for every single patient.

Detailed Description
-----------------
The main objective is to describe the incidence and distribution of tumour biomarkers, and to identify molecular subgroups from a multicentre series of patients who are investigated for and subsequently diagnosed with a pancreatic adenocarcinoma (PDAC) or a precursor lesion or a pancreatic neuroendocrine tumour. The secondary objective is to determine disease control rate (CR, PR and SD >24 weeks), duration of response, progression free survival (PFS) and overall survival (OS) in locally advanced / metastatic patients or relapse free survival (RFS) and overall survival (OS) in early stage curative / pre-cursor lesion patients, associated with the identified molecular subtypes of PDAC pancreatic cancer and relevant anti-cancer therapies. To identify molecular predictors of response or toxicity to standard of care anti-cancer therapies in PDAC/PanNET. The study also has a number of exploratory objectives listed below: Depending on the number of patients assessable for each biomarker of interest and the prevalence of biomarker expression in the study population, exploratory endpoints of this study include: Evaluation of the predictive value of biomarker expression (i.e. the ability of a biomarker to predict responsiveness or resistance to a specific anti-cancer treatment). Evaluation of the prognostic value of biomarker expression (i.e. the ability of a biomarker to predict outcome regardless of a specific anti-cancer treatment). Comparison of biomarker expression among IPMN, MCN, and pancreatic adenocarcinoma and evaluation of their prognostic value.
