The standard therapy of breast cancer has been changed, new therapies brought new side effects and different impacts on quality of life are not sufficiently covered by EORTC QLQ BR-23.
Phases 1 and 2 are completed, the Breast Cancer Module Update has been translated into 11 languages, patient recruitment for phase 3 is finished and data has been evaluated. The manuscript is in progress.

Patient recruitment and data collection for phase 4.
BR-23 is the standard instrument for measuring the quality of life (QoL) in patients with breast cancer. It was developed in 1996. But since this time, changes in treatment have occurred, making an update of the questionnaire necessary. We updated QLQ BR 23. The new QLQ BR 45 contains 45 items. Now we will start with the phase IV of the study, a large scale field study.
