| Scientific title | Utility of biomarkers for ovarian cancer risk assessment in primary care: a pilot study |
| Study objectives | Primary objective: To determine the specificity of HE4 and CA125 in a symptomatic primary care population. Secondary objectives: To estimate the sensitivities of HE4 and CA125 in a symptomatic primary care population. The trialists hypothesize that HE4 will add to the diagnostic accuracy of CA125 in a symptomatic primary care population. They aim to determine the specificity and sensitivity of HE4 as a diagnostic biomarker for ovarian cancer. They will look at its independent performance and its performance in conjunction with CA125. |

| Health condition(s) or problem(s) studied | Ovarian cancer |
| Intervention | Study setting: Central Manchester University Hospitals NHS Foundation Trust (CMFT). This centre receives around 900 CA125 samples from primary care each year. Study duration: Total: 20 months Phase 1: 16 months Phase 2: 20 months Methods overview The study consists of 2 overlapping phases: Phase 1: HE4 testing GP requested CA125 samples sent to MFT for processing over a 16 month period will undergo additional testing for HE4. The study will not interfere with laboratory testing of CA125 and CA125 results will be available to GPs as normal. Following standard CA125 testing by the laboratory team, samples will be scavenged by a member of the MFT laboratory team and stored at -40 degrees in the MFT laboratory. Samples will be tested in batches on a weekly basis by a lab biochemist using Fujirebio HE4 ELISA kits. Following testing, samples will then be retested on the same day for HE4 on the Fujirebio Lumipulse G600 II machine. Samples will then be disposed of in compliance with MFT laboratory protocols. If CA125 is within the normal range and HE4 is elevated on the ELISA kit, a letter will be sent by one of the Gynaecological Oncology Medical Secretaries to the patient and their GP, informing them of the result and providing information on the HE4 test. GPs will be asked to discuss the result with the patient and to offer an appointment with Dr Emma Crosbie at St Mary’s for further discussion of the result. Pseudo-anonymised CA125 and HE4 results will be passed to the research team (only the lab and secretarial team will be able to identify patients from this data) as will unlinked hospital trust specific ‘district numbers’, to allow screening in phase 2. Phase 2: Determination of outcomes For the 16 months of phase 1 and for an additional 4 months, gynaecology referral lists, clinic lists and MDT records at MFT will be monitored to identify patients, by district number, who underwent CA125 and HE4 testing in phase 1 and who were referred by their GP to gynaecology. Patients with elevated HE4 and normal CA125 who were referred to Dr Emma Crosbie’s clinic in phase 1 will be included. These patients will be approached, wherever possible during clinic appointments or inpatient stays, and consent sought for the study team to perform a search of patient hospital notes. In the event that the patient has been identified in Phase 1 as having a raised CA125 or HE4 but is either being managed in the community or referred to an alternate speciality or hospital, the patient will be contacted by telephone and/or by letter, asking for permission to use their data for research. A consent form and participant information sheet will be sent to the patient with a stamped and addressed envelope to return. This will provide us with consent to search their notes to identify outcome data. Hospital notes will be hand searched to identify predetermined information including presenting symptoms, investigations, surgical outcomes and pathology reports, final diagnosis and cancer stage where applicable. These data will be utilised in biomarker evaluation. Patients who are seen at MFT in phase 2 will be asked to provide another blood sample for research purposes. |

| IPD sharing plan summary | Available on request |
| Publication and dissemination plan | The trialists aim to publish their findings in a peer reviewed academic journal. They will also disseminate the results of this study through patient forums, charitable foundations, including Wellbeing of Women, who have funded this study, and through social media. They will present this work at local, national and international academic meetings, depending on the findings, and it will form part of the research thesis of a higher degree at the University of Manchester. |
| IPD sharing plan | The trialists will make anonymised individual patient data available upon reasonable request for other ethically approved research studies once they have reported their study findings in an academic publication. |
