Sensitivity and Specificity of Cytological Samples for Fallopian Tube Involvement

Evaluate the sensitivity and specificity of the cytological samples collected from the fallopian tube in determining the presence or absence of malignancy for fallopian tube involvement as compared to the surgical histology results. Fallopian tube involvement was defined as: 1. Malignant cells that originated in the fallopian tube, detected by the surgical histology results from the fallopian tube. 2. Malignant cells that have migrated to the fallopian tube, detected by surgical histology results of the ovaries or fallopian tube.

Time frame: At the time of the scheduled salpingectomy or salpingo-oophorectomy

Population: The number of Cytuity cell samples, not participants, was used for these endpoint analyses.
