Features of breast cancer screening strategies in older women
Article describes current features of early breast cancer diagnosis in older women. Authors put their attention on main problems and controversies of breast cancer (BC) mammographic screening in older women. Aim was to define relationship between BC incidence in different age groups. Material and methods. Authors analyzed data from Moscow Cancer Registry in 2013-2015. BC incidence in patients 40-74 old and older than 75 years was compared. We used Mann-Whitney U-test for estimation of differences between these groups. Results. BC incidence in women 75 years old or older was in 1.65 times higher than in women 40-74 years old. U-test analysis revealed that there were no differences in amount of firstly diagnosed BC between age groups 40-74 old and older than 75 years (p > 0,05). Also amounts of new BC cases in different age groups were no significant differences (p > 0,05). Age of BC diagnosis dependence on patient age was weaker in patients with late stages of BC. Conclusion. BC mammographic screening should be performed in women 75 years or older. In the absence of sufficient evidences of effectiveness of breast cancer mammographic screening final decision needs to accept individually.
