Worse Breast Cancer Outcomes for Southern Nevadans, Filipina and Black Women.

Breast cancer is the second deadliest cancer for women in the demographically unique mountainous west state of Nevada. This study aims to accurately characterize breast cancer survival among the diverse women of the flourishing Silver State. Nevada Central Cancer Registry data was linked with the National Death Index and the Social Security Administration Masterfile. Overall 5-year age-adjusted cause-specific survival, survival stratified by race/ethnicity, and stage-specific survival stratified by region of Nevada were calculated. Adjusted hazard ratios were computed with Cox proportional hazards regression. 11,111 cases of breast cancer were diagnosed from 2003 to 2010. Overall 5-year breast cancer survival in Nevada was 84.4 %, significantly lower than the US, at 89.2 %. Black and Filipina women had a higher risk of death than white women. Poor survival in the racially and ethnically diverse Las Vegas metropolitan area, with a large foreign-born population, drives Nevada's low overall survival. System-wide changes are recommended to reduce the racial/ethnic disparities seen for black and Filipina women and improve outcomes for all.
