- Workstream 1 is looking at all the information currently available from general practice (demographics, symptoms, clinical findings, blood test results) as well as data from hospitals to develop a risk prediction model for UGI cancers. This has previously been done for single cancer sites but our new approach is for a number of cancers which can give similar symptoms and are difficult to diagnose. We will also focus on how health inequalities influence the timely detection and treatment of UGI cancers.
