Implementation of large-scale HPV self-testing for cervical cancer screening
The goal of this project is to determine the best strategy for integrating a home-testing option for cervical cancer screening. The most sensitive screening test for cervical cancer and precancer is a PCR-based test for human papilloma virus (HPV), which…
Standardized ultrasound-based risk stratification for detection of ovarian cancer
This project, initiated in 2014, led to the development and large-scale implementation of a system for risk stratifying ovarian abnormalities seen on ultrasound to ensure that similar abnormalities are described in a similar way by radiologists. The system also allows…
Evaluating screening participation, follow-up and outcomes for breast, cervical and colorectal cancer in the PROSPR consortium
Cancer screening is a complex process encompassing risk assessment, the initial screening examination, diagnostic evaluation, and treatment of cancer precursors or early cancers. Metrics that enable comparisons across different screening targets are needed. We present population-based screening metrics for breast,…

Automated Cervical Screening and Triage, Based on HPV Testing and Computer-Interpreted Cytology
State-of-the-art cervical cancer prevention includes human papillomavirus (HPV) vaccination among adolescents and screening/treatment of cervical precancer (CIN3/AIS and, less strictly, CIN2) among adults. HPV testing provides sensitive detection of precancer but, to reduce overtreatment, secondary "triage" is needed to predict…
Validation of an HPV DNA cervical screening test that provides expanded HPV typing
Background/Purpose As cervical cancer screening shifts from cytology to human papillomavirus (HPV) testing, a major question is the clinical value of identifying individual HPV types. We aimed to validate Onclarity™ (Becton Dickinson Diagnostics, Sparks MD), a nine-channel HPV test recently…
Human Papillomavirus DNA methylation as a biomarker for cervical precancer: Consistency across 12 genotypes and potential impact on management of HPV-positive women
Human papillomavirus (HPV) DNA methylation testing is a promising triage option for women testing HPV-positive during cervical cancer screening. However, the extent to which methylation indicates precancer for all 12 carcinogenic HPV types has not been evaluated. In this nested…
Effect of Time to Diagnostic Testing for Breast, Cervical, and Colorectal Cancer Screening Abnormalities on Screening Efficacy: A Modeling Study
Background: Patients who receive an abnormal cancer screening result require follow-up for diagnostic testing, but the time to follow-up varies across patients and practices.Methods: We used a simulation study to estimate the change in lifetime screening benefits when time to…
The Women’s Health Initiative (WHI) Life and Longevity After Cancer (LILAC) Study: Description and Baseline Characteristics of Participants
Background: The Women's Health Initiative (WHI) Life and Longevity After Cancer (LILAC) study offers an important opportunity to advance cancer research by extending the original WHI studies to examine survivorship in women diagnosed with cancer during their participation in WHI.Methods:…
Human Immunodeficiency Virus (HIV)- and Non-HIV-Associated Immunosuppression and Risk of Cervical Neoplasia
To estimate the risk of cervical intraepithelial neoplasia grade 2, 2-3, 3, adenocarcinoma in situ, or cancer (CIN 2 or worse) among women with human immunodeficiency virus (HIV)- and non-HIV-associated immunosuppression. We performed a case-control study of 20,146 women with…
Adjuvant gemcitabine-docetaxel chemotherapy for stage I uterine leiomyosarcoma: Trends and survival outcomes
To assess recent trends of administering adjuvant gemcitabine-docetaxel (GD) chemotherapy for Stage I uterine leiomyosarcoma, and to compare disease-free and overall survival between women who received and did not receive adjuvant GD chemotherapy. All patients diagnosed with Stage I uterine…
HPV16 E7 Genetic Conservation Is Critical to Carcinogenesis
Although most cervical human papillomavirus type�16 (HPV16) infections become undetectable within 1-2 years, persistent HPV16 causes half of all cervical cancers. We used a novel HPV whole-genome sequencing technique to evaluate an exceptionally large collection of 5,570 HPV16-infected�case-control samples to…
Impact of body mass index on ovarian cancer survival varies by stage
Research on the effect of body mass index (BMI) on ovarian cancer survival is inconsistent, but previous studies did not consider the possible impact of ascites, bowel obstruction, or cachexia, which commonly occur in late-stage disease. We evaluated the association…
Human papillomavirus vaccination and subsequent cervical cancer screening in a large integrated healthcare system
Human papillomavirus vaccination may result in lowered intention to be screened for cervical cancer, potentially leading to gaps in screening coverage and avoidable cervical cancer diagnoses. The purpose of this study was to examine the association between human papillomavirus vaccination…

Five-year risks of CIN 3+ and cervical cancer among women with HPV testing of ASC-US Pap results
New screening guidelines recommend that human papillomavirus (HPV)-negative/atypical squamous cells of undetermined significance (ASC-US) results be considered as equivalent to HPV-negative/Pap-negative results, leading to rescreening in 5 years. However, despite ample data, the routine clinical performance of HPV testing of…
