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.

Early Detection / Screening
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.

Calculation of a CleoDX Pre-Surgical Triage Test malignancy risk score
Timepoint [1] 338631 0
Scores will be determined retrospectively on completion of study enrollment (anticipated maximum 1 year following surgery).
Secondary outcome [1] 437159 0
Diagnostic sensitivity of CleoDX Pre-Surgical Triage Test malignancy risk score to identify cancer patients
Timepoint [1] 437159 0
Blood samples will be collected at enrollment prior to surgery.. Ultrasound reports and CA125 serum titre will be collected as they become available, which may occur before or after surgery. Any pathology findings will be collected after surgery and histopathological examination of any tissue removed.
Secondary outcome [2] 437684 0
Diagnostic specificity of CleoDX Pre-Surgical Triage Test malignancy risk score to identify cancer patients
Timepoint [2] 437684 0
Blood samples will be collected at enrollment prior to surgery.. Ultrasound reports and CA125 serum titre will be collected as they become available, which may occur before or after surgery. Any pathology findings will be collected after surgery and histopathological examination of any tissue removed.

Can healthy volunteers participate?
No
Key exclusion criteria
1. Pregnant currently / within the last 3 months
2. Current or previous ovarian cancer
3. Prior bilateral oophorectomy or otherwise in surgical menopause
4. Diagnosed with any gynecological malignancy within last 2 years
5. Diagnosed with melanoma within last 2 years
6. Current or prior (previous 12 months) treatment with chemotherapy, radiotherapy or immunotherapy
