The Czech population has high burden of malignant tumors, and screening programs are therefore an essential part of cancer control policy. At the beginning of 2014 personalized invitation of Czech citizens for cancer screening programs was launched to promote higher coverage by screening. The aim of the paper is to present the up-to-date results of the personalized invitation. The data from health insurance companies were used to evaluate the volume of invitations for cancer screening programs and the participation rate after invitation in 2014-2017. During the first four years of the project, over 6 million invitations were sent (approximately 3 million individuals were invited). Participation rates after the first invitation in the breast, colorectal and cervical screening were 22.3%, 21.7% and 15.5%. However, the effect of personalized invitations decreases with repeated invitations to participate. Personalized invitation contributed to screening in hundreds of thousands citizens, but a large proportion of invited people still do not participate. It is necessary to encourage personalized invitation and discuss other strategies to motivate the public to participate in screening programs.
