Validation of Ovarian Adnexal Mass Assessment Score Test System

Interventions

CleoDX ovarian cancer test

Conditions

Ovarian Neoplasms

Eligibility

Age Range

18 Years+

Sex

FEMALE

Inclusion Criteria:

* female patients =\> 18 years of age at the time of consent
* Can provide written informed consent
* Have an ovarian cyst or adnexal mass (simple, complex, or solid ovarian/pelvic mass) identified through imaging examination (e.g. transvaginal ultrasound - TVU) that requires surgery, but have not yet undergone this surgery

Exclusion Criteria:

* Any prior confirmed diagnosis of, or treatment for, ovarian cancer
* Any prior surgery resulting in removal of both ovaries
* Prior history of gynecological malignancy (within last 2 years)
* Prior history of melanoma (within last 2 years)
* Prior treatment (within 12 months of sample collection) with chemotherapy, radiotherapy or immunotherapy
* Immune-compromised. Definition: those whose weakened immune system may render them more susceptible to infection, illness, or complications. These may include patients with immune-suppressive conditions (e.g. HIV/AIDS), patients undergoing immuno-, chemo- or radio-therapy (within the last 12 months) for any reason, receiving immune suppressive therapies (e.g. transplant recipients, individuals with known autoimmune disease), or with a primary immunodeficiency disorder (e.g. Lupus).
* Pregnant currently or within the last 3 months based on participant self-report

Outcome Measures

Primary Outcomes

Calculation of the CleoDX adnexal mass score

Determine the Cleo Diagnostics (CleoDX) adnexal mass score in patients identified with an adnexal mass requiring surgery, but who have not yet undergone this surgery.

Time frame: Outcomes will be assessed during an analysis phase, which will commence after completion of patient recruitment and continue for up to 12 months or the end of the study period is reached (August 2026), whichever occurs first.

Secondary Outcomes

Compare CleoDX adnexal mass score with pre- and post-surgical clinicopathologic information

Correlate post-surgical pathology findings with the CleoDX adnexal mass score, and evaluate the performance metrics (including sensitivity, specificity, Negative Predictive Value and Positive Predictive Value) of the CleoDX adnexal mass assessment scoring system.

Time frame: Outcomes will be assessed during an analysis phase, which will commence after completion of patient recruitment and continue for up to 12 months or the end of the study period is reached (August 2026), whichever occurs first.

Determine performance and accuracy of the CleoDX test against post-surgical pathology findings

Correlate post-surgical pathology findings with the CleoDX adnexal mass score, and evaluate the performance metrics (including sensitivity, specificity, Negative Predictive Value and Positive Predictive Value) of the CleoDX adnexal mass assessment scoring system.

Time frame: Outcomes will be assessed during an analysis phase, which will commence after completion of patient recruitment and continue for up to 12 months or the end of the study period is reached (August 2026), whichever occurs first.

Identify rate of accurately predicted diagnoses by CleoDX compared to that of standard clinical workflow

Demonstrate superiority of the CleoDX adnexal mass scoring system compared to standard clinical workflows including CA125 and Risk of Malignancy Index (RMI) measurements.

Time frame: Outcomes will be assessed during an analysis phase, which will commence after completion of patient recruitment and continue for up to 12 months or the end of the study period is reached (August 2026), whichever occurs first.
