Abstract
PURPOSE: To evaluate the association between functional status based on a geriatric assessment (GA) and outcomes of tolerance to treatment in patients with lung or head and neck cancer receiving radiation therapy (RT) or chemoradiation (CRT).
METHODS AND MATERIALS: A prospective cohort study was conducted in patients aged ≥65 years with head and neck cancer or lung cancer undergoing curative intent RT or CRT. Pretreatment GA, health-related quality of life (HRQoL), and patient-reported outcomes (PRO) were obtained. Questionnaires were repeated biweekly during RT and at 6 weeks after treatment. Dysfunction was defined as scores <14 on the Instrumental Activities of Daily Living scale. Poor tolerance to treatment was defined by hospitalization, >3-day treatment delay, change in RT or CRT regimen, or death. Associations of dysfunction with tolerance to radiation therapy, HRQoL changes, and PRO ratings were evaluated.
RESULTS: Of the 50 patients accrued, 46 had evaluable data. Mean age was 72.5 years (range, 65-92 years). At baseline, 37% had dysfunction. Poor tolerance to RT or CRT occurred in 39%. There was no association between dysfunction and tolerance. Patients with dysfunction had lower baseline HRQoL scores. From baseline to end of RT, those with baseline dysfunction had less of a decline in Role Functioning (P=.01) and Global Health Score (P=.04) domains. However, from end of RT to 6-week follow-up, those with dysfunction were more likely to continue to drop in the Physical, Role Functioning, and Social domains (all P<.01). Dysfunction at baseline was also associated with higher severity of certain PROs.
CONCLUSIONS: Pretreatment dysfunction was associated with continued decline and lack of recovery of HRQoL in this patient population. Larger studies could further elucidate the GA's predictive value.
