BACKGROUND Overall, cervical cancer survival in the United States has been reported to be among the highest in the world, despite slight decreases over the last decade. Objective of the current study was to describe cervical cancer survival trends among US women and examine differences by race and stage. METHODS This study used data from the CONCORD‐2 study to compare survival among women (aged 15‐99 years) diagnosed in 37 states covering 80% of the US population. Survival was adjusted for background mortality (net survival) with state‐ and race‐specific life tables and was age‐standardized with the International Cancer Survival Standard weights. Five‐year survival was compared by race (all races, blacks, and whites). Two time periods, 2001‐2003 and 2004‐2009, were considered because of changes in how the staging variable was collected. RESULTS From 2001 to 2009, 90,620 women were diagnosed with invasive cervical cancer. The proportion of cancers diagnosed at a regional or distant stage increased over time in most states. Overall, the 5‐year survival was 63.5% in 2001‐2003 and 62.8% in 2004‐2009. The survival was lower for black women versus white women in both calendar periods and in most states; black women had a higher proportion of distant‐stage cancers. CONCLUSIONS The stability of the overall survival over time and the persistent differences in survival between white and black women in all US states suggest that there is a need for targeted interventions and improved access to screening, timely treatment, and follow‐up care, especially among black women.
