De (kosten)effectiviteit van het personaliseren van de nacontrole en nazorg voor patiënten NA BORrstkanker: De NABOR-studie

Summary: After curative treatment for non-metastatic breast cancer, patients receive surveillance (detection of possible recurrence of breast cancer in the breast area) and aftercare (support for possible consequences of the disease and/or treatment). Until now, all patients received an annual mammogram for five years, regardless of their risk of recurrence. Within the NABOR study, surveillance plans are personalized in shared decision-making using Breast Cancer Surveillance decision aid, in which the individual risk of recurrence is calculated using the validated INFLUENCE prediction model. Personal aftercare plans are supported by the Breast Cancer Aftercare decision aid. The aim of the study is to determine the (cost-)effectiveness of personalized surveillance and aftercare on patient-reported concerns about cancer recurrence and quality of life. The design is a multiple interrupted time series, in which hospitals switch to using both decision aids via a transition phase. The study aims to include in 10 hospitals 1,040 patients who will be followed for two years.
