Neighborhood Social Vulnerability Linked to Worse Ovarian Cancer Survival, with Disproportionate Impact on Black Women
核心洞察
Women in socially vulnerable neighborhoods face a 20% higher risk of death after an ovarian cancer diagnosis compared to those in less vulnerable areas, according to a Pitt-led study published in JAMA Network Open.
Black women experience a 45% higher risk of death than white women, and the combination of Black race and high neighborhood vulnerability carries a greater risk than either factor alone.
The study analyzed data from 2,544 women (509 Black, 2,035 white) treated at the O'Neal Comprehensive Cancer Center (搜索) at the University of Alabama at Birmingham, linking residential census tracts to the CDC's Social Vulnerability Index.
Women living in socially vulnerable neighborhoods face a 20% higher risk of death after an ovarian cancer diagnosis compared with women in less vulnerable communities, according to a new study led by researchers at the University of Pittsburgh. Published August 10, 2026, in JAMA Network Open, the study also found that Black women face a 45% higher risk of death than white women — and the interaction between race and residential environment may be driving persistent disparities in ovarian cancer survival.
The research, conducted in collaboration with the University of Alabama at Birmingham, the University of South Carolina, the University of Kentucky, and the Ri.MED Foundation, analyzed data from 2,544 women diagnosed with epithelial ovarian cancer (搜索) and treated at the O'Neal Comprehensive Cancer Center (搜索) at the University of Alabama at Birmingham. The cohort included 509 Black women and 2,035 white women.
"We expected residential context to influence outcomes, but what surprised us was how much stronger the impact was for Black women," said Francesmary Modugno, Ph.D., M.S., MPH, professor in the Department of Obstetrics, Gynecology and Reproductive Sciences at Pitt and senior author of the study. "Our findings suggest that it's not simply where someone lives. The interaction between a woman's lived experience and her residential environment may be helping drive these persistent disparities."
The Deadliest Gynecologic Cancer
Epithelial ovarian cancer (搜索) is the deadliest gynecologic cancer, with only about half of patients surviving five years after diagnosis. Survival is even lower among Black women, with fewer than 40% alive five years later. While differences in factors such as age at diagnosis, cancer stage, and tumor type explain some of that disparity, a substantial survival gap remains unexplained.
Researchers hypothesized that factors beyond biology and clinical care may influence survival and sought to determine whether social determinants of health reflected in the communities where patients live could explain the remaining difference in outcomes.
Linking Neighborhood Vulnerability to Survival
The study linked each patient's residential census tract to the Centers for Disease Control and Prevention's Social Vulnerability Index, a measure that incorporates neighborhood-level factors such as poverty, housing conditions, transportation access, educational attainment, and other socioeconomic challenges.
Further analyses showed that Black women were more likely to live in highly vulnerable neighborhoods. Yet residential context alone did not fully explain the survival disparity. Black women experienced worse survival than white women even when living in similarly advantaged communities, and the combination of being Black and living in a highly vulnerable neighborhood was associated with a greater risk of death than would be expected from either factor alone.
Opportunities for Health Systems
The findings point to opportunities for health systems and cancer programs to identify patients at increased risk and provide additional support services. Examples include patient navigation programs, transportation assistance, childcare support, survivorship resources, and other interventions that can help patients complete treatment and manage the challenges associated with cancer care.
"Our findings reinforce that we must better understand and address the barriers patients face in their communities and ensure that every woman has equitable access to high-quality care," said Rebecca Arend, M.D., MSPH, associate professor of gynecology oncology in the Department of Obstetrics and Gynecology at the University of Alabama at Birmingham and associate director of clinical research at the O'Neal Comprehensive Cancer Center (搜索).
"Translating research into meaningful improvements in cancer outcomes is only possible through strong collaborations among academic medical centers, researchers and community partners," Arend added.
Building on Prior Research
The study builds on previous research published in 2025 led by Modugno and Pitt colleagues using data from UPMC Hillman Cancer Center (搜索) in western Pennsylvania, which found that social vulnerability was associated with ovarian cancer survival. The new study expands on those findings by including a substantially larger population of Black women and examining how residential context may contribute to racial disparities in outcomes.
The findings will need to be replicated in other regions of the United States and among additional racial and ethnic groups to determine how broadly they apply. Future studies will also explore other social and environmental factors that may influence ovarian cancer survival, including neighborhood pollution, food access, and community resources.
Ultimately, the researchers hope their findings will lead health systems to develop more targeted approaches to support patients at greatest risk of poor outcomes. By incorporating neighborhood-level measures such as the Social Vulnerability Index into cancer care planning, health systems may be able to better identify patients facing barriers to care and connect them with supportive resources during treatment.
