Mainz, Germany). Instead, an increase in the incidence of lower stages has been observed. One reason for this increase is the change of the staging system from Evans (more stage-3 patients) to INSS (more stage-1 patients). A second reason is the screening program that was introduced in Germany from 1995-2000.
