Analysis of Circulating Epithelial Tumor Cells in Peripheral Blood in Patients With Primary Non-metastatic Breast Cancer Under Adjuvant Radiotherapy

In cooperation with the Women's Hospital of the Friedrich Schiller University in Jena, a total of 161 patients with clinically proven, primarily non-metastatic breast cancer were sampled and examined before and after radiotherapy over a period from 09/2002 to 09/2012. The MAINTRAC method was used to quantitatively determine the amount of CETC in the blood and to observe its peritherapeutic course.
