Review of frailty in geriatric surgical oncology.

Frailty is a common phenomenon in older adult population and associated with an elevated risk of adverse health outcomes. Recent studies have demonstrated that patients with frailty undergoing surgery had a significantly higher morbidity and mortality compared to those without frailty. This is particularly important in patients with cancer because the prevalence of frailty is persistently high across a spectrum of primary cancers. Identifying frailty in oncological patients undergoing surgery may provide an important preoperative intervention opportunity to mitigate operative risks. In this review, we provide an overview of frailty and its association with other geriatric syndromes. We will also review the impact of frailty on postoperative outcomes focusing on the field of surgical oncology. We then describe currently available tools to objectively measure frailty to provide clinicians with various practical tools that may be adopted in their clinical practice. Finally, we will describe potential interventional programs, including the recently introduced Geriatric Surgery Verification program by the American College of Surgeons, that may be institutionally adopted to mitigate postoperative complications and improve meeting patient-centered goals in the frail patient population.
