Abstract
Identifying, understanding, and curing disease is a lifelong endeavor for any medical practitioner. Equally as important is to be cognizant of the impact a disease has on the individual suffering from it, as well as on their family. Ovarian cancer is the leading cause of death from gynecologic malignancies. Symptoms are vague, and the disease is generally at an advanced stage at diagnosis. Efforts have been made to develop methods to identify ovarian cancer at earlier stages, thus improving overall mortality. Transvaginal ultrasound (TVUS), with and without laboratory tests, can be used to screen for ovarian cancer. For over thirty years, the University of Kentucky Markey Cancer Center Ovarian Cancer Screening Program has been studying the efficacy of TVUS for detecting early stage ovarian cancer. After 285,000+ TVUS examinations provided to over 45,000 women, the program has demonstrated that regular TVUS examinations can detect ovarian cancer at early stages, and that survival is increased in those women whose ovarian cancer was detected with screening and who undergo standard treatment. These results demonstrate the utility of TVUS as an efficacious method of ovarian cancer screening.Entities:

Statistical terms and definitions used in ovarian cancer screening [51].
| Term | Screening Result | Findings |
|---|---|---|
| True Positive (TP) | Positive | Histologically-proven ovarian cancer |
| False Positive (FP) | Positive | Benign ovarian histology |
| True Negative (TN) | Negative | No evidence of ovarian cancer 12 months after a negative screen |
| False Negative (FN) | Negative | Ovarian cancer diagnosed within 12 months of a negative screen |
Sensitivity = TP/(TP + FN); Specificity = TN/(TN + FP); Positive Predictive Value = TP/(TP + FP); Negative Predictive Value = TN/(TN + FN). Reproduced from [51] with permission from publisher.
