The goal of this clinical trial is to measure hand grip strength in adults with pancreatic ductal adenocarcinoma (PDAC). The main questions it aims to answer are:
* Is it feasible to measure hand grip strength as part of a clinic visit?
* Are changes in hand grip strength related to changes in body composition?
* Is hand grip strength related to a person's well-being?
* Is hand grip strength related to how a tumour responds to treatment?
Participants will squeeze a device with their hand to measure their hand grip strength and complete questionnaires about their well-being when they are seen in clinic for their regular medical care for PDAC.
