Prehabilitation is the Gateway to Better Functional Outcomes for Individuals with Cancer.

Prehabilitation is a clinical model that introduces components of rehabilitation to patients prior to undergoing intensive medical interventions, such as surgery, in order to optimize function and improve tolerability to the intervention. Cancer care introduces a continuum of sequential or concurrent intensive anti-neoplastic medical interventions that are known to be detrimental to a patient's function. Prehabilitation evidence has grown across several areas of oncology care delivery demonstrating that a multi-modal rehabilitative intervention, delivered prior to oncology-direct therapies, leads to better functional outcomes and improves important endpoints associated with surgery and cancer treatment. This commentary article provides a brief history of the emergence of prehabilitation in cancer care delivery, reviews the current evidence base and guidelines for prehabilitation, and offers insights for future implementation of this model as a standard in oncology care. A prehabilitation program is an optimal starting point for most patients undergoing anti-neoplastic therapy as it serves as a gateway to improving functional outcomes throughout the cancer continuum. Future research in prehabilitation should aim to reach beyond measuring functional outcomes and to explore the impact of this model on important disease treatment endpoints such as tumor response to oncology-directed treatment, impact on treatment-related toxicities, and disease progression.
