Description of intervention(s) / exposure
This study will benchmark the performance of the CleoDX Pre-Surgical triage Test against the use of CA125&transvaginal ultrasound to predict risk of malignancy prior to surgery in patients with an adnexal mass. Patients provide a single serum sample prior to surgical referral, in addition to that provided for standard-of-care tests. There is no patient follow-up required.

The CleoDX Pre-Surgical Test measures a combination of 5 biomarkers in serum (CA125, HE4, IL6, active CXCL10 and total CXCL10) from patients, and combines the result into a single score (from 1-10) as an indicator of malignancy risk. It is used to assist in the pre-surgical determination of likelihood that an adnexal mass may be malignant, and ensure triage to an appropriate surgical expertise for further evaluation.

The test will be indicated for use in patients in whom the presence of an adnexal mass requires surgical intervention, but who have not yet been seen by an oncologist. Typically these patients will have received ultrasound imaging and CA125 test, and the results of the test indicate referral to a surgeon for secondary evaluation is warranted.

Comparator / control treatment
As per standard of care, patients with a suspected adnexal mass undergo (i) transvaginal ultrasound and (ii) CA125 serum testing. These two standard tests are used to assist in determining the risk of malignancy, and refer patients to an appropriate secondary evaluation for surgical intervention. This testing occurs in a general clinical setting for every patient prior to referral.

This trial will access a single serum sample from patients who have already received standard of care testing, and are being referred for surgical evaluation. The serum sample will be accessed from a single blood draw provided at the time of referral, processed through a standard pathology provider network and then stored until sufficient numbers for batch analysis are obtained.

The result of serum testing using the CleoDX test will be retrospectively correlated with pathology findings, and its ability to pre-surgically differentiate benign from malignant masses compared to the initial indication obtained using standard-of-care CA125 and transvaginal ultrasound.

There is no intervention arising as a result of the test findings. The study is purely observational.

Summary
Brief summary
This study will evaluate a diagnostic test for cancer risk before surgery women with an ovarian mass

Who is it for?
You may be eligible to join this study if you are aged 18 years and above and have an ovarian cyst or adnexal mass (simple, complex, or solid ovarian/pelvic mass) identified through imaging examination that requires surgery. You will already have had a CA125 test and a transvaginal ultrasound, and your doctor will have made a decision to send you to a specialist for further examination.

Study details
Cleo Diagnostics Ltd has developed a novel Ovarian Cancer Adnexal Mass Assessment Score test system.

Participants in this study will have a single blood sample taken prior to surgery for testing using the novel Ovarian Cancer Adnexal Mass Assessment Score test system. This test measures five analytes in serum, and combines their values into a single score. This score indicates the likelihood that a mass might be malignant, before surgery is undertaken to determine the nature of the mass.

In this trial the risk score will be compared to pathology findings after surgery, to retrospectively assess its accuracy to predict malignancy.

It is hoped that the test will enhance clinical decision-making and assist in patient referral for further surgical exploration.
