Evaluation of Sarcopenia in Older Patients Undergoing Head and Neck Cancer Surgery.

Abstract

OBJECTIVES/HYPOTHESIS\nSarcopenia is a hallmark of aging and its identification may help predict adverse postoperative events in patients undergoing head and neck surgery. The study objective was to assess the relationship between sarcopenia and postoperative complications and length of stay in patients undergoing major head and neck cancer surgery.\n\n\nSTUDY DESIGN\nProspective cohort study.\n\n\nMETHODS\nA prospective cohort study was performed of patients 50\u2009years and older undergoing major head and neck surgery. Sarcopenia was defined as low muscle mass (determined by neck muscle cross-sectional imaging) with either low muscle strength (grip strength) or low muscle performance (timed walk test). Logistic regression was applied on binary outcomes, and linear regression was used for log-transformed length of hospital stay (LOS). Univariate and multivariate analyses were performed.\n\n\nRESULTS\nOf the 251 patients enrolled, pre-sarcopenia was present in 34.9% (n\xa0=\xa087) and sarcopenia in 15.6% (n\xa0=\xa039) of patients. Patients with sarcopenia were more likely to be older (P\xa0=\u2009.001), female (P\xa0=\u2009.001), have a lower body mass index (P\xa0=\u2009.001), and lower preoperative hemoglobin (P\u2009<\u2009.001). On univariate analysis, the presence and severity of sarcopenia was associated with the development of medical complications (P\xa0=\xa0.029), higher grade of complications (P\xa0=\xa0.032), LOS (P\xa0=\xa0.015), and overall survival (P\xa0=\xa0.001). On multivariate analysis, sarcopenia was associated with a longer LOS (β\xa0=\xa00.32 [95% CI: 0.19-0.45], P\u2009<\u2009.001) and worse overall survival (HR\xa0=\xa02.21 [95% CI: 1.01-4.23], P\xa0=\xa0.017).\n\n\nCONCLUSIONS\nSarcopenia may aid in the prediction of prolonged hospital stay and death in patients who are candidates for major head and neck surgery.\n\n\nLEVEL OF EVIDENCE\n3 Laryngoscope, 2021.
