title: Adjuvant Systemic Therapy in Older Breast Cancer Women: Can We Optimize the Level of Care?
abstract: Defining optimal adjuvant treatment for older women with breast cancer is challenged by the lack of level-1 clinical evidence and the heterogeneity of the older population. Nevertheless, recommendations based on reviews of available evidence mainly from retrospective subgroup analyses and extrapolation of study results from younger patients, and expert opinions, may be useful to guide treatment decisions in fit patients. But how can we properly define a "fit" older patient? In clinical practice, age by itself and clinical impression generally drive treatment decision, although the appropriateness of this judgment is under-documented. Such an approach risks overtreatment or, more frequently, undertreatment. A geriatric assessment can be valuable in oncology practice to address this issue. In this review article, we will focus only on systemic treatment and will discuss "standard" adjuvant systemic treatment strategies for fit older breast cancer patients and the role of "personalized" systemic therapy in unfit patients. The concepts conveyed in this review cannot be extrapolated to locoregional therapy.
