Abstract
Despite the fact that the US population is aging and the numbers of older patients with breast cancer are increasing, many questions remain on how to optimally treat this patient population. Accrual of older cancer patients to clinical trials has been stagnant, and consequently, evidence-based recommendations are often limited by a lack of prospective data to inform decisions. Increasingly, one’s functional status has been recognized as a critical factor in predicting for treatment toxicity, and tools such as the geriatric assessment will likely become a routine part of clinical practice over time. Here, adjuvant treatment considerations for older patients will be reviewed, including what is known about treatment efficacy, utilization patterns, and toxicity for older breast cancer patients. Improving enrollment of older patients onto clinical trials should be a national priority; it is only through prospective assessment that we can improve our approaches to treating our older patients with cancer.
