About

The overarching objective of this project is to develop a pan-gynecologic cancer detection test using gynecologic (unique endometrial, cervical, and ovarian cancer) cancer-specific methylated DNA markers and high-risk human papilloma virus (HR-HPV) detected in vaginal fluid and/or plasma.

This proposal defines Phase II MDM-based cancer detection studies in endometrial cancer (EC) and endometrial hyperplasia with atypia (AEH) in vaginal fluid and 2) ovarian cancer (OC) in plasma and vaginal fluid. Additionally, it defines necessary Phase I MDM-based cancer detection and exploratory aims to test novel cervical cancer (CC) MDMs and test the specificity of cancer-specific MDMs among various common benign gynecologic pathologies.er detection and exploratory aims to test novel cervical cancer MDMs and test the specificity of cancer-specific MDMs among various common benign gynecologic pathologies.

Full description

Detection of endometrial, ovarian, and cervical cancers at an early stage vastly increases the chances of cure and may also avert morbidity secondary to surgical staging, radiation, and/or chemotherapy. Despite the great successes of cervical cancer screening, comparable early detection methods for other gynecologic cancers and their precursors are not available. While nearly 1.5 million women per year in the United States are evaluated for abnormal uterine bleeding (AUB) or postmenopausal bleeding (PMB), the most common symptom of endometrial cancer, most undergo an invasive diagnostic biopsy with the finding of benign etiology.

Vaginal bleeding is often the only presenting symptom of women ultimately diagnosed with endometrial cancer (EC) or its precursor lesion, endometrial hyperplasia(EH). More than 90% of women with EC present with vaginal bleeding. Cervical cancer and cervical dysplasia can present as intermenstrual bleeding, post-coital bleeding, or other abnormal vaginal bleeding. However, most women who present with AUB or PMB have a benign etiology.

There are approximately 70 million women ≥45 years of age in the United States based on the most recent census data. Between 4-11% of women will be worked up for perimenopausal AUB or PMB in their lifetime. As only 5-10% of those women will have an EC or EH, there is a great clinical need for a less invasive clinical diagnostic test that can reliably distinguish between benign uterine bleeding and bleeding associated with an underlying endometrial cancer, cervical cancer, or a precursor lesion.
