Development and proof-of-concept of a multicenter, patient-centered cancer registry for breast cancer patients with metastatic disease-the Breast cancer care for patients with metastatic disease (BRE-4-MED) registry

BackgroundPatients with metastatic breast cancer (MBC) are treated with a palliative approach with focus on controlling for disease symptoms and maintaining high quality of life. Information on individual needs of patients and their relatives as well as on treatment patterns in clinical routine care for this specific patient group are lacking or are not routinely documented in established Cancer Registries. Thus, we developed a registry concept specifically adapted for these incurable patients comprising primary and secondary data as well as mobile-health (m-health) data.MethodsThe concept for patient-centered Breast cancer care for patients with metastatic disease (BRE-4-MED) registry was developed and piloted exemplarily in the region of Main-Franconia, a mainly rural region in Germany comprising about 1.3M inhabitants. The registry concept includes data on diagnosis, therapy, progression, patient-reported outcome measures (PROMs), and needs of family members from several sources of information including routine data from established Cancer Registries in different federal states, treating physicians in hospital as well as in outpatient settings, patients with metastatic breast cancer and their family members. Linkage with routine cancer registry data was performed to collect secondary data on diagnosis, therapy, and progression. Paper and online-based questionnaires were used to assess PROMs. A dedicated mobile application software (APP) was developed to monitor needs, progression, and therapy change of individual patients. Patient's acceptance and feasibility of data collection in clinical routine was assessed within a proof-of-concept study.ResultsThe concept for the BRE-4-MED registry was developed and piloted between September 2017 and May 2018. In total n = 31 patients were included in the pilot study, n = 22 patients were followed up after 1 month. Record linkage with the Cancer Registries of Bavaria and Baden-Wurttemberg demonstrated to be feasible. The voluntary APP/online questionnaire was used by n = 7 participants. The feasibility of the registry concept in clinical routine was positively evaluated by the participating hospitals.ConclusionThe concept of the BRE-4-MED registry provides evidence that combinatorial evaluation of PROMs, needs of family members, and raising clinical parameters from primary and secondary data sources as well as m-health applications are feasible and accepted in an incurable cancer collective.
