Overview
This study is a multi-center, observational study aiming at developing a machine learning-based early detection model using prospectively collected liquid biopsy samples from newly diagnosed ovarian cancer.
Description
Peripheral blood samples from ovarian cancer (OC) patients will be prospectively collected to identify cancer-specific circulating signals by analyzing cell free DNA. Based on the comprehensive molecular profiling, a machine learning-driven noninvasive test will be trained and validated through a two-stage approach in clinically annotated individuals. Approximately 168 stage I-II OC patients will be enrolled in this study. Age-matched female controls included in model development were recruited in another study, which are volunteers without a cancer diagnosis after routine medical screening.
Eligibility
Inclusion Criteria:
- 40-75 years old
- Clinically and/or pathologically diagnosed ovarian cancer

- Able to provide a written informed consent and willing to comply with all part of the protocol procedures
Exclusion Criteria:
- Pregnancy or lactating women
- Known prior or current diagnosis of other types of malignancies comorbidities
- Severe acute infection (e.g. severe or critical COVID-19, sepsis, etc.) or febrile illness (body temperature of ≥ 38.0 °C) within 14 days prior to blood draw
- Recipients of organ transplant or prior bone marrow transplant or stem cell transplant
- Recipients of blood transfusion within 30 days prior to study blood draw
- Recipients of therapy in past 14 days prior to blood draw, including oral or IV antibiotics, glucocorticoid, azacitidine, decitabine, procainamine, hydrazine, arsenic trioxide
- Other conditions that the investigators considered are not suitable for the enrollment
