Ryser MD, et al. - Using the Surveillance, Epidemiology and End Results registry, researchers focused on the recent trends in ductal carcinoma in situ (DCIS) incidence (from 2000 to 2014) in the US. They also compared the observed patterns against trends in mammography use. Findings revealed a stable overall DCIS incidence between 2000 and 2014. Per year, an increase by 1.3% and 0.6% in DCIS incidence has been seen among age groups 20-44 years and 45-55 years, respectively. By 1.6% and 1.0% per year increase in DCIS incidence was evident among black women and women of other races, respectively, while a stable incidence was reported among white women. A good correlation of mammography uptake with DCIS incidence was observed, except for women aged 40-49 years and black women as these women had an increase in DCIS incidence despite stagnating and decreasing mammography uptake, respectively.
