Impact of feeding tubes on prospective functional outcomes in patients with locally advanced head and neck cancer undergoing radiation therapy

Abstract

PurposeThe optimal timing of enteral feeding tube (FT) insertion during radiation therapy for head and neck cancer remains controversial. This study compares prospectively collected functional outcomes for prophylactic versus reactive insertion. Methods and materialsPatients undergoing primary radiation therapy for stage III-IV head and neck cancer between 2004 and 2009 underwent functional outcome assessment at baseline and 3, 6, 12, 24, and 36 months posttreatment. Instruments included the Royal Brisbane Hospital Outcome Measure for Swallowing, Performance Status Scale for Head and Neck Cancer Patients, and modified Edmonton Symptom Assessment Scale. Multivariable regression analysis was conducted to determine the impact of FT use on functional outcomes. ResultsA total of 178 patients were assessed with a median follow-up of 36.4 months. Use of an FT was prophylactic in 92 and reactive in 24; no tube was used in 62 patients. Compared with prophylactic placement, reactive FT use was not associated with worse function for Performance Status Scale for Head and Neck Cancer Patients Normalcy of Diet for soft foods (adjusted odds ratio [AOR] 1.16, P = .85) or Eating in Public (AOR 1.87, P = .31). Similarly, there were no differences in the Royal Brisbane Hospital Outcome Measure for Swallowing for modified diet (AOR 1.27, P = .7) or FT dependence (AOR 3.01, P = .2). ConclusionsThere were no significant differences in long-term swallowing function between patients who received a prophylactic versus reactive FT.
