Immigrant women face barriers navigating the healthcare system, but impact of immigration status on delivery of adjuvant RT for BC has not been studied.<\/p>\n<p><strong>Methods<\/strong> \u2014 A population-level study using provincial databases was conducted including women with Stage I-III breast cancer diagnosed between 2010\u20132016 in Ontario, Canada undergoing breast conserving surgery (BCS). Co-variates including age, co-morbidity, socioeconomic factors, stage, receptor status and treatment facility factors were collected. Primary outcome was the proportion of women undergoing RT and secondary outcome was time from surgery to RT.<\/p>\n<p><strong>Results<\/strong> \u2014 Of 30,712 women, 4,293 (14 %) were immigrants. Immigrants were younger (54.6 vs. 62.5 years) and less often had Stage I (49.4 % vs. 57.0 %) disease. Odds of receiving RT after BCS was 0.81 (95 %CI 0.74\u20130.89p &lt; 0.0001) for immigrant vs. non-immigrant women. When stratified by age, immigrant women &lt; 70 were less likely to receive RT when compared to non-immigrants, while no differences were observed for those \u2265 70. There was a small, though significant difference in mean wait-time from surgery to RT in patients who did not receive chemotherapy [immigrant vs non-immigrant 72.7 days (28.8 SD) vs. 77.7 days (31.0 SD), p &lt; 0.0001].<\/p>\n<p><strong>Conclusion<\/strong> \u2014 Our study demonstrates a lower proportion of immigrant women receiving RT after BCS compared to non-immigrant women. There was a small difference in wait-time to radiation. Further research is needed to explore system, provider, and patient factors driving this difference.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction \u2014 Radiation therapy (RT) is an essential component of treatment for breast cancer (BC), and while indications and delivery techniques evolve, inequities in access remain.
