Groundbreaking research reveals dramatic disparities in breast cancer outcomes between Haitian women living in Haiti versus those who have immigrated to Miami.
In the world of modern medicine, where breakthroughs in cancer treatment make headlines regularly, it's easy to assume that quality care is equally accessible to all. Yet for women of Haitian descent, where they live significantly impacts whether they'll survive breast cancer. Groundbreaking research reveals a disturbing disparity: Haitian women living in Haiti experience dramatically worse breast cancer outcomes compared to those who have immigrated to Miami, even when we might expect them to share similar genetic backgrounds and risk profiles.
Higher risk of death for women in Haiti
Median delay in seeking care in Haiti
Advanced stage diagnosis in Haiti
This isn't just about statistics—it's about real women whose survival depends on complex factors including geographic access to care, socioeconomic resources, and healthcare infrastructure. A retrospective cohort study comparing these two populations uncovers a troubling gap that highlights the profound impact of our environment and healthcare systems on something as deeply personal as cancer survival 1 .
The research compared 102 Haitian immigrants presenting at the University of Miami/Jackson Memorial Hospital with 94 residents in Haiti presenting at the Innovating Health International Women's Cancer Center in Port-au-Prince 1 . The findings paint a stark picture of healthcare disparity.

These disparities translated into life-or-death consequences. The percentage of women who died was nearly double in Haiti (31.9% vs. 17.6%), and the risk of death was three times higher for women in Haiti after adjusting for other factors 1 .
To understand how researchers uncovered these disparities, let's examine the study design that made these comparisons possible.
This retrospective cohort study compared two distinct groups of Haitian women with newly diagnosed breast cancer 1 :
Identified through the University of Miami/Jackson Memorial Hospital breast cancer clinic roster between 2008-2014
Identified through the Innovating Health International Women's Cancer Center database between 2013-2015
All patients were confirmed through detailed chart review, with ethical approvals obtained from both Haitian and U.S. review boards
Researchers tracked several key metrics to compare the experiences and outcomes of these two groups 1 :
Time from diagnosis to death from any cause
Time from diagnosis to relapse, disease progression, or death
Stage at diagnosis, estrogen receptor status, HER2 status
Types and timing of interventions received
The statistical analysis employed sophisticated methods including Kaplan-Meier survival curves and Cox regression models to compare survival between the groups while accounting for other variables that might influence outcomes.
The most compelling findings emerged in the survival analysis 1 :
| Survival Metric | Women in Haiti | Haitian Immigrants in Miami |
|---|---|---|
| Median Survival Time | 53.7 months | Not reached during study period |
| Mortality Rate | 31.9% | 17.6% |
| Adjusted Death Risk | 3.09 times higher | Reference group |
Note: The "not reached" median survival indicates more than half of Miami patients were still alive at the end of data collection 1 .
The adjusted hazard ratio of 3.09 indicates that, even after accounting for other factors, women in Haiti faced three times the risk of death compared to their counterparts in Miami 1 . This striking difference underscores that where a woman receives care can be as important as the biological characteristics of her cancer.
What drives these dramatic disparities? The answer lies in a complex interplay of structural, biological, and resource-based factors that go far beyond simple explanations.
The 20-month median delay from symptom onset to medical evaluation in Haiti represents perhaps the most modifiable factor in this disparity. Several elements contribute to this dangerous delay 1 :
Limited access to screening programs compared to the more established screening infrastructure in Miami
Financial barriers to seeking care, including direct costs and lost wages
Geographic barriers with limited transportation options to specialized cancer centers
Cultural and educational factors that may affect when and how women seek medical attention
Interestingly, the study revealed biological differences that can't be explained by access to care alone. Haitian women had significantly higher rates of estrogen receptor-negative tumors (44.9% vs. 26.5%), which tend to be more aggressive and less responsive to standard hormonal therapies 1 . The reasons for this biological difference remain unexplained and warrant further investigation.
Even after diagnosis, women in Haiti faced significant limitations in available treatments 1 :
Only about half of biopsies from Haiti had estrogen receptor status tested
HER2 testing was rarely performed since trastuzumab (Herceptin) was unavailable
Fewer options for breast-conserving surgery and radiation therapy
These resource constraints created a cascade effect where limited diagnostics led to limited treatment options, which in turn compromised outcomes.
This research provides not just a stark comparison but also a roadmap for addressing global cancer disparities. The promising outcomes for Haitian immigrants in Miami demonstrate that improved survival is achievable with appropriate healthcare infrastructure and access.
Strengthening primary care and screening systems in underserved regions
Implementing patient navigation programs to guide women through complex healthcare systems
Developing adapted treatment guidelines for resource-limited settings
Fostering international collaborations to build sustainable cancer care capacity
The story of Haitian women with breast cancer on both sides of the Caribbean Sea reveals a troubling truth: in the 21st century, your survival from a common cancer still depends heavily on where you live. The three-fold difference in mortality risk between Haitian immigrants in Miami and residents in Haiti represents not just a statistical finding but a collective failure in global health equity.
Yet within this sobering reality lies hope—the demonstrated success of Haitian immigrants in Miami shows that with appropriate resources and timely care, outcomes can significantly improve. Addressing these disparities requires acknowledging that biology alone doesn't determine survival; our healthcare systems, social structures, and commitment to equity play equally important roles.
As we continue to advance our technical capabilities in cancer treatment, studies like this remind us that the most profound breakthroughs may not come from new drugs alone, but from ensuring that the treatments we already have reach everyone who needs them, regardless of nationality or geography.
