Current projects: Emergency presentation of cancer survey The UK Acute Oncology Society (UKAOS) Malignancy of unknown origin (MUO) subgroup are scoping how patients with MUO start their clinical journey from acute presentation to definitive management. We know that:
Final report - pending Board approval in April 2026. Working Group - MUO diagnosis standards Following the MUO survery a working group has been establised to work on a UKAOS standard for care document for MUO. Standard of Care (SoC) for Malignancy of Undefined Origin (MUO) 1. Purpose and context The Standard of Care document outlines the minimum requirements for identifying, investigating, managing, and following up patients with Malignancy of Undefined Origin (MUO). It aims to ensure timely diagnosis, appropriate escalation, clear clinical ownership, and equitable access to specialist services. Recognising that there is existing guidance, this SoC has been constructed by a range of experts to provide best practice clinical guidance. It builds on existing national guidelines but incorporates the lived experience of those involved in managing these patients. The intent is to supplement rather than replace existing local or national documents. Once this document has been finalised and approved it will be added here. This group also hope to work on suite of resouces for teams working with MUO pathways this will include patient information.
