ANGLE has developed the Parsortix™ Cell Separation System (Parsortix), an automated system capable of harvesting rare circulating cells for analysis from a sample of peripheral blood based on cellular size and deformability. In a small pilot study, scientists at the Medical University of Vienna demonstrated that measurement of a combination of mRNA markers extracted from CTCs captured using the Parsortix system could be used to identify women with ovarian cancer. This study is designed to provide specimens for optimization of an assay using clinical and biomarker information (i.e. demographics, imaging results and/or serum tumor markers) in combination with mRNA extracted from rare cells in the blood of women presenting with a pelvic mass for the detection of malignancy.
Primary Objective: Optimization of an assay for the differentiation of women with benign pelvic masses from those with malignant pelvic masses using mRNA markers extracted from CTCs isolated from whole blood. Multiple serum tumor markers and mRNA markers will be measured, and the results will be compared to the actual clinical diagnosis made for each patient through other recognized methods (e.g. histopathology). The blood samples collected in the course of this study will be used to finalize the selection of mRNA and/or serum tumor markers to be evaluated in future prospective studies.
Exploratory Objective: Use statistical modeling to determine the need for and/or preliminary design of a mathematical algorithm to combine the multiple serum tumor and/or mRNA markers for estimation of the risk of ovarian cancer.

Women with a pelvic mass
Women diagnosed with a pelvic mass (defined as a simple, complex or a solid ovarian cyst / pelvic mass) who are scheduled for a laparotomy or laparoscopy for removal of the pelvic mass. Must have a pelvic imaging study performed within 60 days prior to surgery and a research blood draw within 60 days prior to surgery.
Procedure: Pelvic imaging
Within 60 days prior to the pelvic mass evaluation procedure, each subject must have a pelvic imaging study (e.g. ultrasound, CT scan, MRI, etc.) conducted and read to visualize the pelvic mass according to the current standard of care. Results of the pelvic imaging study(ies) will be recorded.
Procedure: Blood draw
Within 60 days prior to, or on the day of the pelvic mass surgery, collect up to 35mL of whole blood into one 5mL SST tube, which must be drawn first, followed by three separate 10mL EDTA tubes.
Other Name: phlebotomy
Procedure: laparotomy or laparoscopy
A laparotomy or laparoscopic procedure will be performed by a qualified individual for excision of the pelvic mass. Representative tissue samples will be taken from the excised pelvic mass and evaluated in pathology departments within each institution according to institutional guidelines. Results from the histopathological evaluation will be recorded, including the final diagnosis along with histological sub-type, and if available, stage and grade of cancer where disease is identified.
- Histopathological diagnosis [ Time Frame: Within 30 days after biopsy or surgical procedure to evaluate pelvic mass ]Tissue samples taken from the pelvic mass will be evaluated in the local institutional pathology department according to institutional guidelines. Results from the histopathological evaluation, including the final diagnosis (i.e. benign, malignant, etc.), histopathology description, and, if malignant, clinical or surgical staging and tumor subtype, will be recorded.
- Presence or absence of circulating tumor cells [ Time Frame: Up to 60 days prior to surgical procedure to evaluate pelvic mass ]Blood from EDTA tubes will be pooled and processed on the Parsortix System to capture and harvest rare cells. The captured rare cells will be eluted (harvested) and lysed, and total RNA will be extracted from the cell lysate for evaluation of multiple gene targets using quantitative PCR (qPCR).
- Serum protein markers [ Time Frame: Up to 60 days prior to surgical procedure to evaluate pelvic mass ]Serum from SST tube will be used for protein biomarker testing.
