Longitudinal Assessment of Frailty and Quality of Life in Patients Undergoing Head and Neck Surgery.

Objective: To understand changes in frailty and quality of life (QOL) in frail versus non-frail patients undergoing surgery for head and neck cancer (HNC).

Methods: Prospective cohort study of patients (median age 67 (50, 88)) with HNC undergoing surgery from December 2011 to April 2014. Fried's Frailty Index, Vulnerable Elders Survey (VES-13), and comprehensive QOL assessments (EORTC QLQ-C30 and HN35) were completed at baseline and 3, 6, and 12-month post-operative visits. Change in frailty and QOL over time was compared between frailty groups (non-frail (score 0), pre-frail (score 1-2), and frail (score 3-5)) using a mixed effects model. Predictors of long-term elevated frailty (12 months > baseline) were analyzed using logistic regression.

Results: The study had 108 patients classified as non-frail (47%), 104 pre-frail (mean (SD) 1.3 (0.4), 45%), and 17 frail (3.4 (0.6); 7%). Frailty score decreased significantly for frail patients 3 months post-operatively (2.1 (1.0); P = .002) and remained significantly lower than baseline at 6 and 12 months (2.1 (1.4); P = .0008 and 2.2 (1.5); P = .005, respectively) while frailty score increased for non-frail patients at 3 months (1.1 (1.0); P < .001) and then decreased. Forty-eight patients (21%) had long-term elevated frailty, with baseline frailty and marital status identified as predictors on univariate analysis. The frail population had significantly worse QOL scores at baseline, which persisted 12 months post-operatively.

Conclusions: Frail patients demonstrate a decrease in frailty score following surgical treatment of HNC. Frail patients have significantly worse QOL scores on longitudinal assessment and would benefit from supportive services throughout their care.
