RESUMEN
OBJECTIVE: There is variation in practice in the treatment of older women with breast cancer. International guidelines highlight the importance of patient autonomy in treatment decision-making. The aim of this study is to identify factors which influence decision-making in older women with operable breast cancer, which will enable us to further understand how to support these patients. METHODS: Systematic review in accordance with the PRISMA guidelines was performed to identify factors which influence treatment decision-making in older women with operable breast cancer. Medline, Web of Science and SCOPUS were searched. RESULTS: The search yielded 5840 results; 13 articles met the inclusion criteria and reported on a total of 1118 women. Thematic analysis identified three key themes in which decision-making factors could be categorised. These were healthcare-related factors, patient-related factors and impact of treatment. Healthcare-related factors included communication with clinicians and provision of information. Patient-related factors were age, pre-existing knowledge, preconceptions of breast cancer and treatment, decision-making style and co-morbidities. The impact of treatment considerations included body image and effect on quality of life. Decision-making style was frequently reported; older women did not demonstrate one preferred style. CONCLUSIONS: The findings have highlighted the complex interplay of factors which influence how older women make breast cancer treatment-decisions. Clinicians should have an awareness of the factors highlighted to maximise their ability to provide support and personalised care to older women with breast cancer whilst treatment decisions are made.
