Prehabilitation for Older Adults Undergoing Lung Cancer Surgery: A Literature Review and Needs Assessment

Abstract

Early-stage lung cancer patients are increasingly considered for preoperative systemic therapy. Older adults in particular are among the most vulnerable patients, with little known on how preoperative therapies affect the risk-benefit of surgery. We sought to summarize the current literature and elucidate existing evidence gaps on the effects of prehabilitation interventions relative to age-related functional impairments and the unique needs of older patients undergoing lung cancer surgery. A literature review was performed using PubMed and Google Scholar databases, of all scientific articles published through April 2022 which report on the effects of prehabilitation on patients undergoing lung cancer surgery. We extracted current prehabilitation protocols and their impact on physical functioning, resilience, and patient-reported outcomes of older patients. Emerging evidence suggests that prehabilitation may enhance functional capacity and minimize the untoward effects of surgery for patients following lung resection similar to, or potentially even better than, traditional postoperative rehabilitation. The impact of preoperative interventions on surgical risk due to frailty remains ill-defined. Most studies evaluating prehabilitation include older patients, but few studies report on activities of daily living, self-care, mobility activities, and psychological resilience in older individuals. Preliminary data suggest the feasibility of physical therapy and resilience interventions in older individuals concurrent with systemic therapy. Future research is needed to determine best prehabilitation strategies for older lung cancer patients aimed to optimize age-related impairments and minimize surgical risk.
