Metastatic breast cancer (MBC) patient outcomes may vary according to distinct health care payers and different countries. We compared 291 Alberta (AB), Canada and 9429 US patients < 65 with de novo MBC diagnosed from 2010 through 2014. Data were extracted from the provincial Breast Data Mart and from the National Cancer Institute’s SEER program. US patients were divided by insurance status (US privately insured, US Medicaid or US uninsured). Kaplan-Meier and log-rank analyses were used to assess differences in OS and hazard ratios (HR) were estimated using Cox models. Multivariate models were adjusted for age, surgical status, and biomarker profile. No difference in OS was noted between AB and US patients (HR = 0.92 (0.77–1.10), p = 0.365). Median OS was not reached for the US privately insured and AB groups, and was 11 months and 8 months for the US Medicaid and US uninsured groups, respectively. The 3-year OS rates were comparable between US privately insured and AB groups (53.28% (51.95–54.59) and 55.54% (49.49–61.16), respectively). Both groups had improved survival (p < 0.001) relative to the US Medicaid and US uninsured groups [39.32% (37.25–41.37) and 40.53% (36.20–44.81)]. Our study suggests that a universal health care system is not inferior to a private insurance-based model for de novo MBC.

Breast cancer is the most frequently diagnosed cancer in the United States and ranks second as the most common cause of cancer-related death among women (Siegel et al., 2020). According to American Cancer Society (ACS) estimates, approximately 276,480 new cases of breast cancer would have been diagnosed in 2020, and greater than 42,000 deaths would be attributed to breast cancer (ACS, 2020). Although only 7% of all cancer-related deaths are from breast cancer every year, it is the leading cause of death among women between the ages of 40 and 49 years (Siegel et al., 2020). The death rate associated with breast cancer, however, has decreased by 1.3% annually from 2013 to 2017.
