The absolute reduction in the risk of relapse following adjuvant radiotherapy in early breast cancer can vary in patients according to prognostic factors. In this situation it is key that health care professionals are able to communicate information about benefits and risks in a balanced way. Shared decision making (SDM) using a patient decision aid (PDA) intends to help the patient to make a decision whether or not to receive radiotherapy. The aim of this study is to test whether a PDA can facilitate the involvement of patients and doctors in SDM.

Materials and methods

We are planning a multicenter study, where the doctors are randomized to use or not to use the developed PDA informing the patients about benefits and risks receiving adjuvant radiotherapy. The study is planned to include 300 patients offered adjuvant radiotherapy after breast‐conserving surgery for T1‐2, N0‐N1mi, M0 disease. The PDA is developed in collaboration with participating radiotherapy centres, patient representatives and Centre for Shared Decision Making.


The primary endpoint testing the involvement of patients in the decision process about their own radiotherapy will be evaluated using the 9‐item SDM Questionnaire (SDM‐Q‐9). Furthermore, we will test how the developed PDA will affect the fear of recurrence using FCRI‐SF as well as the overall satisfaction with the decision using the decisional conflict scale and the Decisional regret scale before and at 6 month after inclusion.


The study will be conducted on behalf of the Danish Breast Cancer Cooperative Group Radiotherapy Committee and planned to start ultimo 2018. In the start‐up phase of the study, courses in SDM will be arranged several places in the country in collaboration with Centre for Shared Decision Making. These courses are supported by a grant from the Danish Comprehensive Cancer Center, to develop a group focusing on SDM in radiotherapy of breast cancer.
