Association of Deficits Identified by Geriatric Assessment with Deterioration of Health-Related Quality of Life in Patients Treated for Head and Neck Cancer

Abstract

Importance: Accumulation of geriatric deficits, leading to an increased frailty state, makes patients susceptible for decline in health-related quality of life (HRQOL) after treatment for head and neck cancer (HNC). Objective: To assess the association of single and accumulated geriatric deficits with HRQOL decline in patients after treatment for HNC. Design, Setting, and Participants: Between October 2014 and May 2016, patients at a tertiary referral center were included in the Oncological Life Study (OncoLifeS), a prospective data biobank, and followed up for 2 years. A consecutive series of 369 patients with HNC underwent geriatric assessment at baseline; a cohort of 283 patients remained eligible for analysis, and after 2 years, 189 patients remained in the study. Analysis was performed between March and November 2020. Interventions or Exposures: Geriatric assessment included scoring of the Adult Comorbidity Evaluation 27, polypharmacy, Malnutrition Universal Screening Tool, Activities of Daily Living, Instrumental Activities of Daily Living (IADL), Timed Up & Go, Mini-Mental State Examination, 15-item Geriatric Depression Scale, marital status, and living situation. Main Outcomes and Measures: The primary outcome measure was the Global Health Status/Quality of Life (GHS/QOL) scale of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. Differences between patients were evaluated using linear mixed models at 3 months after treatment (main effects, ß [95% CI]) and declining course per year during follow-up (interaction × time, ß [95% CI]), adjusted for baseline GHS/QOL scores, and age, sex, stage, and treatment modality. Results: Among the 283 patients eligible for analysis, the mean (SD) age was 68.3 (10.9) years, and 193 (68.2%) were male. Severe comorbidity (ß = -7.00 [-12.43 to 1.56]), risk of malnutrition (ß = -6.18 [-11.55 to -0.81]), and IADL restrictions (ß = -10.48 [-16.39 to -4.57]) were associated with increased GHS/QOL decline at 3 months after treatment. Severe comorbidity (ß = -4.90 [-9.70 to -0.10]), IADL restrictions (ß = -5.36 [-10.50 to -0.22]), restricted mobility (ß = -6.78 [-12.81 to -0.75]), signs of depression (ß = -7.08 [-13.10 to -1.06]), and living with assistance or in a nursing home (ß = -8.74 [-15.75 to -1.73]) were associated with further GHS/QOL decline during follow-up. Accumulation of domains with geriatric deficits was a major significant factor for GHS/QOL decline at 3 months after treatment (per deficient domain ß = -3.17 [-5.04 to -1.30]) and deterioration during follow-up (per domain per year ß = -2.74 [-4.28 to -1.20]). Conclusions and Relevance: In this prospective cohort study, geriatric deficits were significantly associated with HRQOL decline after treatment for HNC. Therefore, geriatric assessment may aid decision-making, indicate interventions, and reduce loss of HRQOL. Trial Registration: trialregister.nl Identifier: NL7839.
