Characterisation and outcomes of patients referred to a regional cancer of unknown primary team: a 10-year analysis.

Background: In the United Kingdom, national guidance published in 2010 recommended the establishment of specialist teams to improve clinical pathways for patients presenting with malignancies of undefined primary origin (MUO) and cancer of unknown primary (CUP). This study sought to define outcomes of patients referred to a regional MUO/CUP service.

Methods: Data were collected prospectively on all patients (n = 1225) referred to a regional CUP team over a 10-year period.
