Abstract
Purpose/Objective(s): Many patients will require parenteral nutrition due to dysphagia during definitive radiation therapy for locally advanced head and neck cancer. However, the optimal timing of feeding tube (FT) insertion (prophylactic versus reactive) remains controversial. This study describes prospectively collected functional outcomes comparing prophylactic versus reactive FTs. Materials/Methods: Patients undergoing definitive radiation therapy for stage III and IV head and neck cancer between 2004 and 2009 prospectively underwent functional outcome assessment at baseline and 3, 6, 12, 24, and 36 months post-treatment. The use of FT and timing of insertion was at the discretion of the attending oncologist. Instruments included the Royal Brisbane Hospital Outcome Measure for Swallowing (RBHOMS), the Performance Status Scale for Head and Neck Cancer Patients (PSSHN), and the Edmonton Symptom Assessment Scale. Multivariable analysis was conducted to determine the significance of FT status while controlling for potential confounding variables including age, gender, tumor stage, chemotherapy use, and primary site of disease. Results: A total of 178 patients were assessed with a median follow-up of 36.4 months. FTs were inserted prophylactically in 92 (51.7%), reactively in 23 (12.9%), and no tube in 63 (35.4%) patients. Compared to patients who received a prophylactic FT, those who had a reactive FT did not have a statistically significant difference in worse swallowing functional outcomes for PSS-HN subscales of eating in public (adjusted odds ratio [AOR] 1.65, p Z 0.42), understandability of speech (AOR 0.73, p Z 0.58), and normalcy of diet (AOR 1.39, pZ 0.66). Similarly, there were no differences in the RBHOMS levels for modified diet (AOR 1.00, pZ 0.99) and FT dependence (AOR 1.78, p Z 0.37). Patients who completed treatment without a FT had statistically significantly improved functional outcomes in PSS-HN and RBHOMS scores compared to both FT groups. Conclusions: Patients who received a reactive FT did not have a statistically significant difference in long-term functional outcomes compared to those with a prophylactically inserted FT. These findings warrant confirmation in a larger cohort of patients and should be considered when comparing the risks and benefits of different strategies for FT placement. Author Disclosure: H.C.
