Thieme E-Journals - Geburtshilfe und Frauenheilkunde / Abstract (thieme-connect.com)

Die Patientin erhielt eine Afterloading-Therapie mit 5 × 5 Gy Einzeldosis tumorumschließend

The patient was given brachytherapy (single dosis of 5 Gy, covering the tumour, total dose 25 Gy)

In the linked article it's been translated as covering the tumour.

"In HDR brachytherapy, an applicator is placed in proximity to the tumour and a single sealed radioactive source attached to a guide wire is electromechanically moved to different positions within the applicator to create a dose distribution covering the tumour. The position of the source within the applicator and the dwell time at each position are varied to create the desired dose distribution covering the tumour."
