RESUMEN
PURPOSE: Little is known about the epidemiology of breast cancer in developing countries, and Haiti has perhaps the least data of any country in the Western Hemisphere. METHODS: We conducted a retrospective review of all patients enrolled in an ongoing breast cancer treatment program in Port-au-Prince, Haiti, from July 1, 2013, through June 30, 2017. Data were drawn from each patient's electronic medical record, paper chart, and biopsy results. RESULTS: The records of 525 women with breast cancer were reviewed for this study. The median age at presentation was 49 years (n = 507). The risk factors observed were as follows: postmenopausal, 50.8% (n = 354); nulliparity, 15.7% (n = 338); hormonal contraception use, 35.0% (n = 309); never breastfed, 20.6% (n = 316); family history of any cancer, 22.0% (n = 295); overweight, 51.5% (n = 332); and smoking, 5.0% (n = 338). Of all those staged, 83.9% (n = 447) of the patients presented with stage III/IV disease and more than half delayed care for > 12 months after first noticing a breast mass. For the subset of tumors for which estrogen receptor (ER; n = 245) and human epidermal growth factor receptor 2 (HER2; n = 179) status was available, the prevalence of ER-positive tumors was 51.8%, of HER2-positive tumors was 19.6%, and of triple-negative tumors was 38.5%. The 12-month mortality rate (n = 425) was 18.4% overall and 27.5% for those who presented with stage IV disease. Median survival was not reached. CONCLUSION: Breast cancer in Haiti presents at an early age and advanced stage. Triple-negative, ER-negative, and high-grade tumors are common. Delays in seeking care and incomplete treatment likely contribute to the high mortality rate; however, as in black women in the United States, the distribution of tumor types may contribute to disparate outcomes.

PURPOSE: The nonprofit Project Medishare launched a breast cancer treatment program in Port-au-Prince in July 2013 to address the demand for breast cancer care in Haiti. We outline the development of the program, highlight specific challenges, and discuss key considerations for others working in global oncology. METHODS: We reflected on our experiences in the key areas of developing partnerships, building laboratory capacity, conducting medical training, using treatment algorithms, and ensuring access to safe, low-cost chemotherapy drugs. We also critically reviewed our costs and quality measures. RESULTS: The program has treated a total of 139 patients with breast cancer with strong adherence to treatment regimens in 85% of patients. In 273 chemotherapy administrations, no serious exposure or adverse safety events were reported by staff. The mortality rate for 94 patients for whom we have complete data was 24% with a median survival time of 53 months. Our outcome data were likely influenced by stage at presentation, with more than half of patients presenting more than 12 months after first noticing a tumor. Future efforts will therefore focus on continuing to improve the level of care, while working with local partners to spread awareness, increase screening, and get more women into care earlier in the course of their disease. CONCLUSION: Our experiences may inform others working to implement protocol-based cancer treatment programs in resource-poor settings and can provide valuable lessons learned for future global oncology efforts.
