A Diagnostic Test to Evaluate Cancer Risk Before Surgery in Women with an Ovarian Mass

Официальное название

Validation of Ovarian Adnexal Mass Assessment Score Test System

Обзор

Ovarian cancer is a serious health risk with the highest death rate among gynecological cancers. Unfortunately, it's only possible to definitively diagnose ovarian cancer after surgery, as there are no reliable tests to determine if an ovarian abnormality is cancerous or benign before surgery. Cleo Diagnostics have developed a new test that uses five biomarkers in the blood to better differentiate between benign and malignant ovarian conditions. In initial studies, this test outperformed the current standard test, CA125, in identifying cancer. This study aims to evaluate the effectiveness of the Cleo Diagnostics (CleoDX) Ovarian Adnexal Mass Score Test System. This test measures five analytes in the blood and provides a score indicating the likelihood of cancer in patients with an adnexal mass requiring surgery. The test is designed to assist doctors in making better-informed decisions about surgery and patient care by providing a more accurate pre-surgical assessment of cancer risk. By doing so, it aims to improve patient outcomes and ensure that those with malignant conditions receive the appropriate specialist care.

Вмешательства

• Диагностический тест CleoDX ovarian cancer test
  A diagnostic test to assist in predicting risk of malignancy prior to surgery for patients with an adnexal mass.

Первичные конечные точки

• Calculation of the CleoDX adnexal mass score [Срок оценки: 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.]

Вторичные конечные точки (3)

• Compare CleoDX adnexal mass score with pre- and post-surgical clinicopathologic information [Срок оценки: 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 [Срок оценки: 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 [Срок оценки: 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.]

Критерии участия

Критерии включения

• 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

Критерии исключения

• 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
